I had this problem trying save a dictionary to NSUserDefaults. It turns out it wouldn't save because it contained NSNull values. So I just copied the dictionary into a mutable dictionary removed the nulls then saved to NSUserDefaults

NSMutableDictionary* dictionary = [NSMutableDictionary dictionaryWithDictionary:dictionary_trying_to_save];
[dictionary removeObjectForKey:@"NullKey"];
[[NSUserDefaults standardUserDefaults] setObject:dictionary forKey:@"key"];

In this case I knew which keys might be NSNull values.

-(void)saveToUserDefaults:(NSString*)string_to_store keys:(NSString *)key_for_the_String
{
    NSUserDefaults *standardUserDefaults = [NSUserDefaults standardUserDefaults];

    if (standardUserDefaults) {
        [standardUserDefaults setObject:string_to_store forKey:key_for_the_String];
        [standardUserDefaults synchronize];
    }
}

And call it by:

[self saveToUserDefaults:@"string_to_store" : @"key_for_the_string"];

Retrieve the string by using:

NSString * stored_string = [[NSUserDefaults standardUserDefaults] stringforkey:key_for_the_String]

Swift 3 / 4:

Here is a simple extension for Int/Double/Float/Bool key-value types that mimic the Optional-return behavior of the other types accessed through UserDefaults.

(Edit Aug 30 2018: Updated with more efficient syntax from Leo's suggestion.)

extension UserDefaults {
    /// Convenience method to wrap the built-in .integer(forKey:) method in an optional returning nil if the key doesn't exist.
    func integerOptional(forKey: String) -> Int? {
        return self.object(forKey: forKey) as? Int
    }
    /// Convenience method to wrap the built-in .double(forKey:) method in an optional returning nil if the key doesn't exist.
    func doubleOptional(forKey: String) -> Double? {
        return self.object(forKey: forKey) as? Double
    }
    /// Convenience method to wrap the built-in .float(forKey:) method in an optional returning nil if the key doesn't exist.
    func floatOptional(forKey: String) -> Float? {
        return self.object(forKey: forKey) as? Float
    }
    /// Convenience method to wrap the built-in .bool(forKey:) method in an optional returning nil if the key doesn't exist.
    func boolOptional(forKey: String) -> Bool? {
        return self.object(forKey: forKey) as? Bool
    }
}

They are now more consistent alongside the other built-in get methods (string, data, etc.). Just use the get methods in place of the old ones.

let AppDefaults = UserDefaults.standard

// assuming the key "Test" does not exist...

// old:
print(AppDefaults.integer(forKey: "Test")) // == 0
// new:
print(AppDefaults.integerOptional(forKey: "Test")) // == nil

UserDefault+Helper.swift

import UIKit

private enum Defaults: String {
   case countryCode = "countryCode"
   case userloginId   = "userloginid"
}

final class UserDefaultHelper {

static var countryCode: String? {
    set{
        _set(value: newValue, key: .countryCode)
    } get {
        return _get(valueForKay: .countryCode) as? String ?? ""
    }
}

static var userloginId: String? {
    set{
        _set(value: newValue, key: .userloginId)
    } get {
        return _get(valueForKay: .userloginId) as? String ?? ""
    }
}

private static func _set(value: Any?, key: Defaults) {
    UserDefaults.standard.set(value, forKey: key.rawValue)
}

private static func _get(valueForKay key: Defaults)-> Any? {
    return UserDefaults.standard.value(forKey: key.rawValue)
}

static func deleteCountryCode() {
    UserDefaults.standard.removeObject(forKey: Defaults.countryCode.rawValue)
 }

static func deleteUserLoginId() {
    UserDefaults.standard.removeObject(forKey: Defaults.userloginId.rawValue)
 }
}

Usage:

Save Value:

UserDefaultHelper.userloginId = data["user_id"] as? String

Fetch Value:

let userloginid = UserDefaultHelper.userloginId

Delete Value:

UserDefaultHelper.deleteUserLoginId()

If you are working with Swift 5+ you have to use UserDefaults.standard.setValue(value, forKey: key) and to get saved data you have to use UserDefaults.standard.dictionary(forKey: key).

Okey so thanks to @bploat and the link to http://www.codingexplorer.com/nsuserdefaults-a-swift-introduction/

I've found that the answer is quite simple for some basic string storage.

let defaults = NSUserDefaults.standardUserDefaults()

// Store
defaults.setObject("theGreatestName", forKey: "username")

// Receive
if let name = defaults.stringForKey("username")
{
    print(name)
    // Will output "theGreatestName"
}

I've summarized it here http://ridewing.se/blog/save-local-data-in-swift/

If you need an ARC version of the wrapper here is the link https://gist.github.com/1170641 Thanks to

NSDictionary *defaultsDictionary = [[NSUserDefaults standardUserDefaults] dictionaryRepresentation];
for (NSString *key in [defaultsDictionary allKeys]) {
                    [[NSUserDefaults standardUserDefaults] removeObjectForKey:key];
}

If anybody is looking for a swift version:

1) Create a custom class for your data

class customData: NSObject, NSCoding {
let name : String
let url : String
let desc : String

init(tuple : (String,String,String)){
    self.name = tuple.0
    self.url = tuple.1
    self.desc = tuple.2
}
func getName() -> String {
    return name
}
func getURL() -> String{
    return url
}
func getDescription() -> String {
    return desc
}
func getTuple() -> (String,String,String) {
    return (self.name,self.url,self.desc)
}

required init(coder aDecoder: NSCoder) {
    self.name = aDecoder.decodeObjectForKey("name") as! String
    self.url = aDecoder.decodeObjectForKey("url") as! String
    self.desc = aDecoder.decodeObjectForKey("desc") as! String
}

func encodeWithCoder(aCoder: NSCoder) {
    aCoder.encodeObject(self.name, forKey: "name")
    aCoder.encodeObject(self.url, forKey: "url")
    aCoder.encodeObject(self.desc, forKey: "desc")
} 
}

2) To save data use following function:

func saveData()
    {
        let data  = NSKeyedArchiver.archivedDataWithRootObject(custom)
        let defaults = NSUserDefaults.standardUserDefaults()
        defaults.setObject(data, forKey:"customArray" )
    }

3) To retrieve:

if let data = NSUserDefaults.standardUserDefaults().objectForKey("customArray") as? NSData
        {
             custom = NSKeyedUnarchiver.unarchiveObjectWithData(data) as! [customData]
        }

Note: Here I am saving and retrieving an array of the custom class objects.

Best solution for me, detecting if a device is mobile or not:

@media (pointer:none), (pointer:coarse) {
}

Try this:

<marquee behavior="" Height="200px"  direction="up" scroll onmouseover="this.setAttribute('scrollamount', 0, 0);this.stop();" onmouseout="this.setAttribute('scrollamount', 3, 0);this.start();" scrollamount="3" valign="center">

    <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
    </marquee>

Sounds like the instance was launched in VPC and while doing so, the check-box for Automatically assign a public IP address to your instances was not checked. Hence the instance does not have a public IP

You can assign an Elastic IP to this instance and then log in using that IP.

Thank you guys for this answers. But I think the accepted answer needs more clarity, As i found difficulty in getting the solution.

1. We may set the environment variable as mentioned in the answer by w0rldart .

   In this case(after seting envmnt var) we may run the phpFile by opening start >> CMD and typing commands like,

   php.exe <path to file location>

   or

   php <path to file location>

   example:

   php.exe C:\xampp\htdocs\test.php
   

2. you can open Start >> CMD as administrator and write like

   <path to php.exe in xampp's php folder> <path to file location>

   example:

   C:\xampp\php\php.exe C:\xampp\htdocs\test.php
   

   or

   C:\xampp\php\php C:\xampp\htdocs\test.php
   

Hopes this will help somebody.

what about using aggregate framework:

db.collection.aggregate({ $group : { _id: null, max: { $max : "$age" }}});

Use PowerMockito on top of Mockito.

Example code:

@RunWith(PowerMockRunner.class)
@PrepareForTest(DriverManager.class)
public class Mocker {

    @Test
    public void shouldVerifyParameters() throws Exception {

        //given
        PowerMockito.mockStatic(DriverManager.class);
        BDDMockito.given(DriverManager.getConnection(...)).willReturn(...);

        //when
        sut.execute(); // System Under Test (sut)

        //then
        PowerMockito.verifyStatic();
        DriverManager.getConnection(...);

    }

Like others have mentioned, create your modal with display:block

<div class="modal in" tabindex="-1" role="dialog" style="display:block">
...

Place the backdrop anywhere on your page, it does not necesarily need to be at the bottom of the page

<div class="modal-backdrop fade show"></div> 

Then, to be able to close the dialog again, add this

<script>
    $("button[data-dismiss=modal]").click(function () {
        $(".modal.in").removeClass("in").addClass("fade").hide();
        $(".modal-backdrop").remove();
    });
</script>

Hope this helps

In addition to registering a ByteArrayHttpMessageConverter, you may want to use a ResponseEntity instead of @ResponseBody. The following code works for me :

@RequestMapping("/photo2")
public ResponseEntity<byte[]> testphoto() throws IOException {
    InputStream in = servletContext.getResourceAsStream("/images/no_image.jpg");

    final HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.IMAGE_PNG);

    return new ResponseEntity<byte[]>(IOUtils.toByteArray(in), headers, HttpStatus.CREATED);
}

You can try this:

func tableView(tableView: UITableView!, canEditRowAtIndexPath indexPath: NSIndexPath!) -> Bool {
    return true
}

func tableView(tableView: UITableView!, commitEditingStyle editingStyle:   UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath!) {
    if (editingStyle == UITableViewCellEditingStyle.Delete) {
        NamesTable.beginUpdates()
        Names.removeAtIndex(indexPath!.row)
        NamesTable.deleteRowsAtIndexPaths([indexPath], withRowAnimation: nil)
        NamesTable.endUpdates()

    }
}

Add this option:

"bInfo": false

I found that skipping the quotation marks "" around the file and location name displayed the image... I am doing this on MacBook....

CPMSifDlg::EncodeAndSend() method is declared as non-static and thus it must be called using an object of CPMSifDlg. e.g.

CPMSifDlg obj;
return obj.EncodeAndSend(firstName, lastName, roomNumber, userId, userFirstName, userLastName);

If EncodeAndSend doesn't use/relate any specifics of an object (i.e. this) but general for the class CPMSifDlg then declare it as static:

class CPMSifDlg {
...
  static int EncodeAndSend(...);
  ^^^^^^
};

java.time

Using the java.time framework built into Java 8 and later. See Tutorial.

import java.time.LocalTime;
import java.time.LocalDateTime;

LocalDateTime now = LocalDateTime.now(); # 2015-11-19T19:42:19.224
# start of a day
now.with(LocalTime.MIN); # 2015-11-19T00:00
now.with(LocalTime.MIDNIGHT); # 2015-11-19T00:00

If you do not need time-of-day (hour, minute, second etc. parts) consider using LocalDate class.

LocalDate.now(); # 2015-11-19

you can measure how long your program works. The following functions help measure the CPU time since the start of the program:

• C++ (double)clock() / CLOCKS PER SEC with ctime included.
• python time.clock() returns floating-point value in seconds.
• Java System.nanoTime() returns long value in nanoseconds.

my reference: Algorithms toolbox week 1 course part of data structures and algorithms specialization by University of California San Diego & National Research University Higher School of Economics

so you can add this line of code after your algorithm

cout << (double)clock() / CLOCKS_PER_SEC ;

Expected Output: the output representing the number of clock ticks per second

When you are using JVM in 32-bit mode, the maximum heap size that can be allocated is 1280 MB. So, if you want to go beyond that, you need to invoke JVM in 64-mode.

You can use following:

$ java -d64 -Xms512m -Xmx4g HelloWorld

where,

• -d64: Will enable 64-bit JVM
• -Xms512m: Will set initial heap size as 512 MB
• -Xmx4g: Will set maximum heap size as 4 GB

You can tune in -Xms and -Xmx as per you requirements (YMMV)

A very good resource on JVM performance tuning, which might want to look into: http://java.sun.com/javase/technologies/hotspot/gc/gc_tuning_6.html

Try this: If your collection was 'example'

db.example.update({}, {$unset: {words:1}}, false, true);

Refer this:

http://www.mongodb.org/display/DOCS/Updating#Updating-%24unset

UPDATE:

The above link no longer covers '$unset'ing. Be sure to add {multi: true} if you want to remove this field from all of the documents in the collection; otherwise, it will only remove it from the first document it finds that matches. See this for updated documentation:

https://docs.mongodb.com/manual/reference/operator/update/unset/

Example:

db.example.update({}, {$unset: {words:1}} , {multi: true});

You can use Enumerable.Except to get distinct items from lines3 which is not in lines2:

lines2.AddRange(lines3.Except(lines2));

If lines2 contains all items from lines3 then nothing will be added. BTW internally Except uses Set<string> to get distinct items from second sequence and to verify those items present in first sequence. So, it's pretty fast.

Try this:

jQuery('#myInput').keypress(function(e) {
    code = e.keyCode ? e.keyCode : e.which;
    if(code.toString() == 13) {
        alert('You pressed enter!');
    }
});

The scripts in this page helped me come up with the script below, which I think is more complete and universal. Basically it will validate any number of radio buttons in a form, meaning that it will make sure that a radio option has been selected for each one of the different radio groups within the form. e.g in the test form below:

   <form id="FormID">

    Yes <input type="radio" name="test1" value="Yes">
    No <input type="radio" name="test1" value="No">

    <br><br>

    Yes <input type="radio" name="test2" value="Yes">
    No <input type="radio" name="test2" value="No">

   <input type="submit" onclick="return RadioValidator();">

The RadioValidator script will make sure that an answer has been given for both 'test1' and 'test2' before it submits. You can have as many radio groups in the form, and it will ignore any other form elements. All missing radio answers will show inside a single alert popup. Here it goes, I hope it helps people. Any bug fixings or helpful modifications welcome :)

<SCRIPT LANGUAGE="JAVASCRIPT">
function RadioValidator()
{
    var ShowAlert = '';
    var AllFormElements = window.document.getElementById("FormID").elements;
    for (i = 0; i < AllFormElements.length; i++) 
    {
        if (AllFormElements[i].type == 'radio') 
        {
            var ThisRadio = AllFormElements[i].name;
            var ThisChecked = 'No';
            var AllRadioOptions = document.getElementsByName(ThisRadio);
            for (x = 0; x < AllRadioOptions.length; x++)
            {
                 if (AllRadioOptions[x].checked && ThisChecked == 'No')

While these answers are correct, they are more mathematically intense than necessary. Assume map coordinates, where the most north point is the highest point on the map. Find the most north point, and if 2 points tie, it is the most north then the most east (this is the point that lhf uses in his answer). In your points,

point[0] = (5,0)

point[1] = (6,4)

point[2] = (4,5)

point[3] = (1,5)

point[4] = (1,0)

If we assume that P2 is the most north then east point either the previous or next point determine clockwise, CW, or CCW. Since the most north point is on the north face, if the P1 (previous) to P2 moves east the direction is CW. In this case, it moves west, so the direction is CCW as the accepted answer says. If the previous point has no horizontal movement, then the same system applies to the next point, P3. If P3 is west of P2, it is, then the movement is CCW. If the P2 to P3 movement is east, it's west in this case, the movement is CW. Assume that nte, P2 in your data, is the most north then east point and the prv is the previous point, P1 in your data, and nxt is the next point, P3 in your data, and [0] is horizontal or east/west where west is less than east, and [1] is vertical.

if (nte[0] >= prv[0] && nxt[0] >= nte[0]) return(CW);
if (nte[0] <= prv[0] && nxt[0] <= nte[0]) return(CCW);
// Okay, it's not easy-peasy, so now, do the math
if (nte[0] * nxt[1] - nte[1] * nxt[0] - prv[0] * (nxt[1] - crt[1]) + prv[1] * (nxt[0] - nte[0]) >= 0) return(CCW); // For quadrant 3 return(CW)
return(CW) // For quadrant 3 return (CCW)

I would recommend using Glazed Lists for this. It makes it very easy to map a data structure to a table model.

To react to the mouseclick on the JTable, use an ActionListener: ActionListener on JLabel or JTable cell

Except struct you can also use array module

import array
values = array.array('l') # array of long integers
values.read(fin, 1) # read 1 integer
file_size  = values[0]

I have same issue with IIS, i uninstalled IIS. Type in run services.msc, I see "wampapache64" service was not running, when I start it using right click it give me error.

I just used these steps.

1. Click on WAMP icon select Apache -> Service -> Remove Service

2. Click on Wamp icon select Apache -> Service -> Install Service

Got green Wamp icon :(

One can also do this with a compact version of @TomAugspurger's answer, like so:

df = df1.merge(df2, how='left', on=['Year', 'Week', 'Colour']).merge(df3[['Week', 'Colour', 'Val3']], how='left', on=['Week', 'Colour'])

You can set an ENV if you want your Time.now and DateTime.now to respond in UTC time.

require 'date'
Time.now #=> 2015-11-30 11:37:14 -0800
DateTime.now.to_s #=> "2015-11-30T11:37:25-08:00"
ENV['TZ'] = 'UTC'
Time.now #=> 2015-11-30 19:37:38 +0000
DateTime.now.to_s #=> "2015-11-30T19:37:36+00:00"

It's possible with const qualifier for State:

virtual const ULONG Write(const ULONG &State = 0, bool sequence = true);

Can't install RMagick 2.13.2. in ubuntu 17.10

My decision

 - sudo apt-get purge imagemagick libmagickcore-dev libmagickwand-dev
 - sudo apt-get autoremove
 - sudo rm /usr/bin/Magick-config

 - sudo apt-get install imagemagick libmagickwand-dev

Version is required to correctly specify the path to the configuration

• cd /usr/lib/x86_64-linux-gnu
• View version ImageMagick, my version ImageMagick - 6.9.7.
• cd ImageMagick-6.9.7/
• ls
• look at the name of the directory bin-q16 or bin-Q16

Creating a link to the config

sudo ln -s /usr/lib/x86_64-linux-gnu/ImageMagick-version/bin-directory/Magick-config /usr/bin/Magick-config

Creating for my version ImageMagick

 - sudo ln -s /usr/lib/x86_64-linux-gnu/ImageMagick-6.9.7/bin-q16/Magick-config /usr/bin/Magick-config
 - bundle

This worked for me:

#!/bin/bash

#Variables
FILELOCAL=/var/www/folder/$(date +'%Y%m%d_%H-%M-%S').csv    
SFTPHOSTNAME="myHost.com"
SFTPUSERNAME="myUser"
SFTPPASSWORD="myPass"
FOLDER="myFolderIfNeeded"
FILEREMOTE="fileNameRemote"

#SFTP CONNECTION
sshpass -p $SFTPPASSWORD sftp $SFTPUSERNAME@$SFTPHOSTNAME << !
    cd $FOLDER
    get $FILEREMOTE $FILELOCAL
    ls
   bye
!

Probably you have to install sshpass:

sudo apt-get install sshpass

I ran into a similar situation trying to convert a table with several 100k rows with a C++ program (MFC/ODBC).

Since this operation took a very long time, I figured bundling multiple inserts into one (up to 1000 due to MSSQL limitations). My guess that a lot of single insert statements would create an overhead similar to what is described here.

However, it turns out that the conversion took actually quite a bit longer:

        Method 1       Method 2     Method 3 
        Single Insert  Multi Insert Joined Inserts
Rows    1000           1000         1000
Insert  390 ms         765 ms       270 ms
per Row 0.390 ms       0.765 ms     0.27 ms

So, 1000 single calls to CDatabase::ExecuteSql each with a single INSERT statement (method 1) are roughly twice as fast as a single call to CDatabase::ExecuteSql with a multi-line INSERT statement with 1000 value tuples (method 2).

Update: So, the next thing I tried was to bundle 1000 separate INSERT statements into a single string and have the server execute that (method 3). It turns out this is even a bit faster than method 1.

Edit: I am using Microsoft SQL Server Express Edition (64-bit) v10.0.2531.0

Since the problem is the non-trivial destructor so if the destructor is removed from the std::string, it's possible to define a constexpr instance of that type. Like this

struct constexpr_str {
    char const* str;
    std::size_t size;

    // can only construct from a char[] literal
    template <std::size_t N>
    constexpr constexpr_str(char const (&s)[N])
        : str(s)
        , size(N - 1) // not count the trailing nul
    {}
};

int main()
{
    constexpr constexpr_str s("constString");

    // its .size is a constexpr
    std::array<int, s.size> a;
    return 0;
}

Figured it out. Used this instead.

$('.div_class').load('http://en.wikipedia.org/wiki/Cross-origin_resource_sharing #toctitle');

This worked for me to solve jpeg and zlib error :

In JavasSript there are 5 primitive data types String , Number , Boolean , null and undefined. I will try to explain with some simple example

lets say we have a simple function

 function test(a) {

     if(a == null){
        alert("a is null");
     } else {
        alert("The value of a is " + a);
     }
  }

also in above function if(a == null) is same as if(!a)

now when we call this function without passing the parameter a

   test(); it will alert "a is null";
   test(4); it will alert "The value of a is " + 4;

also

var a;
alert(typeof a); 

this will give undefined; we have declared a variable but we have not asigned any value to this variable; but if we write

var a = null;
alert(typeof a); will give alert as object

so null is an object. in a way we have assigned a value null to 'a'

char word[length];
char *rtnPtr = word;
...
return rtnPtr;

This is not good. You are returning a pointer to an automatic (scoped) variable, which will be destroyed when the function returns. The pointer will be left pointing at a destroyed variable, which will almost certainly produce "strange" results (undefined behaviour).

You should be allocating the string with malloc (e.g. char *rtnPtr = malloc(length)), then freeing it later in main.

jQuery .live() has been removed in version 1.9 onwards.

That means if you are upgrading from version 1.8 and earlier, you will notice things breaking if you do not follow the migration guide below. You must not simply replace .live() with .on()!

Read before you start doing a search and replace:

For quick/hot fixes on a live site, do not just replace the keyword live with on,
as the parameters are different!

.live(events, function)

should map to:

.on(eventType, selector, function)

The (child) selector is very important! If you do not need to use this for any reason, set it to null.

Migration Example 1:

before:

$('#mainmenu a').live('click', function)

after, you move the child element (a) to the .on() selector:

$('#mainmenu').on('click', 'a', function)

Migration Example 2:

before:

$('.myButton').live('click', function)

after, you move the element (.myButton) to the .on() selector, and find the nearest parent element (preferably with an ID):

$('#parentElement').on('click', '.myButton', function)

If you do not know what to put as the parent, body always works:

$('body').on('click', '.myButton', function)

SQL injection should not be prevented by trying to validate your input; instead, that input should be properly escaped before being passed to the database.

How to escape input totally depends on what technology you are using to interface with the database. In most cases and unless you are writing bare SQL (which you should avoid as hard as you can) it will be taken care of automatically by the framework so you get bulletproof protection for free.

You should explore this question further after you have decided exactly what your interfacing technology will be.

A lazy way that works for me,

$ brew install coreutils
$ ln -s /usr/local/bin/greadlink /usr/local/bin/readlink
$ which readlink
/usr/local/bin/readlink
/usr/bin/readlink

On OSX Mavericks I created a bash script named vscode (adapted from the .bashrc in VSCode Setup) in ~/bin:

#!/bin/bash

if [[ $# = 0 ]]
then
    open -a "Visual Studio Code"
else
    [[ $1 = /* ]] && F="$1" || F="$PWD/${1#./}"
    open -a "Visual Studio Code" --args "$F"
fi

vscode <file or directory> now works as expected.

If you want to prevent your script failing and collect the return code:

command () {
    return 1  # or 0 for success
}

set -e

command && returncode=$? || returncode=$?
echo $returncode

returncode is collected no matter whether command succeeds or fails.

Probably the simplest way to achieve this is with git archive. If you really need just the expanded tree you can do something like this.

git archive master | tar -x -C /somewhere/else

Most of the time that I need to 'export' something from git, I want a compressed archive in any case so I do something like this.

git archive master | bzip2 >source-tree.tar.bz2

ZIP archive:

git archive --format zip --output /full/path/to/zipfile.zip master 

git help archive for more details, it's quite flexible.

Be aware that even though the archive will not contain the .git directory, it will, however, contain other hidden git-specific files like .gitignore, .gitattributes, etc. If you don't want them in the archive, make sure you use the export-ignore attribute in a .gitattributes file and commit this before doing your archive. Read more...

Note: If you are interested in exporting the index, the command is

git checkout-index -a -f --prefix=/destination/path/

(See Greg's answer for more details)

In newer version of windows the Certuil has [CertificateStoreName] where we can give the store name. In earlier version windows this was not possible.

Installing *.pfx certificate: certutil -f -p "" -enterprise -importpfx root ""

For more details below command can be executed in windows cmd. C:>certutil -importpfx -? Usage: CertUtil [Options] -importPFX [CertificateStoreName] PFXFile [Modifiers]

For sake of completeness, here is a script which actually could be a one-liner to get a backup from a database, excluding (ignoring) all the views. The db name is assumed to be employees:

ignore=$(mysql --login-path=root1 INFORMATION_SCHEMA \
    --skip-column-names --batch \
    -e "select 
          group_concat(
            concat('--ignore-table=', table_schema, '.', table_name) SEPARATOR ' '
          ) 
        from tables 
        where table_type = 'VIEW' and table_schema = 'employees'")

mysqldump --login-path=root1 --column-statistics=0 --no-data employees $ignore > "./backups/som_file.sql"   

You can update the logic of the query. In general using group_concat and concat you can generate almost any desired string or shell command.

Shorter version:

db.row_factory = lambda c, r: dict([(col[0], r[idx]) for idx, col in enumerate(c.description)])

Okay, after testing, here is a better, cleaner solution.

$('#FirstName').bind('keyup', function () {

    // Get the current value of the contents within the text box
    var val = $('#FirstName').val().toUpperCase();

    // Reset the current value to the Upper Case Value
    $('#FirstName').val(val);

});

Sort of. As Bobby says:

svn co file:///.../trunk/foo file:///.../trunk/bar file:///.../trunk/hum

will get the folders, but you will get separate folders from a subversion perspective. You will have to go separate commits and updates on each subfolder.

I don't believe you can checkout a partial tree and then work with the partial tree as a single entity.

awk '{ sum += $2; n++ } END { if (n > 0) print sum / n; }'

Add the numbers in $2 (second column) in sum (variables are auto-initialized to zero by awk) and increment the number of rows (which could also be handled via built-in variable NR). At the end, if there was at least one value read, print the average.

awk '{ sum += $2 } END { if (NR > 0) print sum / NR }'

If you want to use the shebang notation, you could write:

#!/bin/awk

{ sum += $2 }
END { if (NR > 0) print sum / NR }

You can also control the format of the average with printf() and a suitable format ("%13.6e\n", for example).

You can also generalize the code to average the Nth column (with N=2 in this sample) using:

awk -v N=2 '{ sum += $N } END { if (NR > 0) print sum / NR }'

$data = DB::table('borrowers')
        ->join('loans', 'borrowers.id', '=', 'loans.borrower_id')
        ->select('borrowers.*', 'loans.*')   
        ->where('loan_officers', 'like', '%' . $officerId . '%')
        ->where('loans.maturity_date', '<', date("Y-m-d"))
        ->get();

You need to first run initdb. It will create the database cluster and the initial setup

See How to configure postgresql for the first time? and http://www.postgresql.org/docs/8.4/static/app-initdb.html

Following up on @Bruno Bronosky and @mrteatime, I offer the suggestion that you just write your boolean return "backwards". This is what I mean:

foo()
{
    if [ "$1" == "bar" ]; then
        true; return
    else
        false; return
    fi;
}

That eliminates the ugly two line requirement for every return statement.

If you want to do this in a single line, try:

Object.keys(a).map(function(key){return a[key]})

I figured it out. The problem was that there were still some pages in the project that hadn't been converted to use "namespaces" as needed in a web application project. I guess I thought that it wouldn't compile if there were still any of those pages around, but if the page didn't reference anything from outside itself it didn't appear to squawk. So when it was saying that it didn't inherit from "System.Web.UI.Page" that was because it couldn't actually find the class "BasePage" at run time because the page itself was not in the WebApplication namespace. I went through all my pages one by one and made sure that they were properly added to the WebApplication namespace and now it not only compiles without issue, it also displays normally. yay!

what a trial converting from website to web application project can be!

You may need a plugin to do this. You can try the command line cc.ddl(delete duplicate lines) of ConyEdit. It is a cross-editor plugin for the text editors, including Notepad++.

With ConyEdit running in background, follow the steps below:

1. enter the command line cc.ddl at the end of the text.
2. copy the text and the command line.
3. paste, then you will see what you want.

Example

Based on the answer I linked to in my comment above, this should work:

delete from
(
select pf.* From PRODUCTFILTERS pf 
where pf.id>=200 
And pf.rowid in 
  (
     Select rowid from PRODUCTFILTERS 
     inner join PRODUCTS on PRODUCTFILTERS.PRODUCTID = PRODUCTS.ID 
     And PRODUCTS.NAME= 'Mark'
  )
); 

or

delete from PRODUCTFILTERS where rowid in
(
select pf.rowid From PRODUCTFILTERS pf 
where pf.id>=200 
And pf.rowid in 
  (
     Select PRODUCTFILTERS.rowid from PRODUCTFILTERS 
     inner join PRODUCTS on PRODUCTFILTERS.PRODUCTID = PRODUCTS.ID 
     And PRODUCTS.NAME= 'Mark'
  )
); 

Use:

<a href="wantedText{/*/properties/property[@name='report']/@value)}"></a>

Yes Fiddler is an option for me:

1. Open Fiddler menu > Rules > Customize Rules (this effectively edits CustomRules.js).
2. Find the function OnBeforeResponse

3. Add the following lines:

   oSession.oResponse.headers.Remove("X-Frame-Options");
   oSession.oResponse.headers.Add("Access-Control-Allow-Origin", "*");
   

4. Remember to save the script!

I had the same problem. I installed "XCode: development tools" from the app store and it fixed the problem for me.

I think this link will help: https://itunes.apple.com/us/app/xcode/id497799835?mt=12&ls=1

Credit to Yann Ramin for his advice. I think there is a better solution with links, but this was easy and fast.

Good luck!

Run query is sql tab

SHOW CREATE TABLE tableName

Click on

+Options -> Choose Full texts -> Click on Go

Copy Create Table query and paste where you want to create new table.

People hate on tables for non-tabular data, but what you're asking for is exactly what tables are good at. <table width="100%">

public void Method()
{
    if(something)
    {
        //some code
        if(!something2)
        {
            return;
        }
    }
    // The code i want to go if the second if is true
}

Change visible="false" to style="visibility:hidden" on your tags..

or better use a class to show/hide the labels..

.hidden{
   visibility:hidden;
}

then on your labels add class="hidden"

and with your script remove the class

document.getElementById("endTimeLabel").className = 'hidden'; // to hide

and

document.getElementById("endTimeLabel").className = ''; // to show

For splitting an InputStream in two, while avoiding to load all data in memory, and then process them independently:

1. Create a couple of OutputStream, precisely: PipedOutputStream
2. Connect each PipedOutputStream with a PipedInputStream, these PipedInputStream are the returned InputStream.
3. Connect the sourcing InputStream with just created OutputStream. So, everything read it from the sourcing InputStream, would be written in both OutputStream. There is not need to implement that, because it is done already in TeeInputStream (commons.io).

4. Within a separated thread read the whole sourcing inputStream, and implicitly the input data is transferred to the target inputStreams.

   public static final List<InputStream> splitInputStream(InputStream input) 
       throws IOException 
   { 
       Objects.requireNonNull(input);      
   
       PipedOutputStream pipedOut01 = new PipedOutputStream();
       PipedOutputStream pipedOut02 = new PipedOutputStream();
   
       List<InputStream> inputStreamList = new ArrayList<>();
       inputStreamList.add(new PipedInputStream(pipedOut01));
       inputStreamList.add(new PipedInputStream(pipedOut02));
   
       TeeOutputStream tout = new TeeOutputStream(pipedOut01, pipedOut02);
   
       TeeInputStream tin = new TeeInputStream(input, tout, true);
   
       Executors.newSingleThreadExecutor().submit(tin::readAllBytes);  
   
       return Collections.unmodifiableList(inputStreamList);
   }
   

Be aware to close the inputStreams after being consumed, and close the thread that runs: TeeInputStream.readAllBytes()

In case, you need to split it into multiple InputStream, instead of just two. Replace in the previous fragment of code the class TeeOutputStream for your own implementation, which would encapsulate a List<OutputStream> and override the OutputStream interface:

public final class TeeListOutputStream extends OutputStream {
    private final List<? extends OutputStream> branchList;

    public TeeListOutputStream(final List<? extends OutputStream> branchList) {
        Objects.requireNonNull(branchList);
        this.branchList = branchList;
    }

    @Override
    public synchronized void write(final int b) throws IOException {
        for (OutputStream branch : branchList) {
            branch.write(b);
        }
    }

    @Override
    public void flush() throws IOException {
        for (OutputStream branch : branchList) {
            branch.flush();
        }
    }

    @Override
    public void close() throws IOException {
        for (OutputStream branch : branchList) {
            branch.close();
        }
    }
}

del array[0]

where 0 is the index of the object in the list (there is no array in python)

If you mean that you wanna attach this to your panel (Window that you are working with).

then you have to create an inner class that extend from IKeyListener interface and then add that method in to the class.

Then, attach that class to you panel by: this.addKeyListener(new subclass());

The params object is included in $stateParams, but won't be part of the url.

1) In the route configuration:

$stateProvider.state('edit_user', {
    url: '/users/:user_id/edit',
    templateUrl: 'views/editUser.html',
    controller: 'editUserCtrl',
    params: {
        paramOne: { objectProperty: "defaultValueOne" },  //default value
        paramTwo: "defaultValueTwo"
    }
});

2) In the controller:

.controller('editUserCtrl', function ($stateParams, $scope) {       
    $scope.paramOne = $stateParams.paramOne;
    $scope.paramTwo = $stateParams.paramTwo;
});

3A) Changing the State from a controller

$state.go("edit_user", {
    user_id: 1,                
    paramOne: { objectProperty: "test_not_default1" },
    paramTwo: "from controller"
});

3B) Changing the State in html

<div ui-sref="edit_user({ user_id: 3, paramOne: { objectProperty: 'from_html1' }, paramTwo: 'fromhtml2' })"></div>

Example Plunker

You use dependency injection when you exactly know what type of objects you require at this point of time. While in case of factory pattern, you just delegate the process of creating objects to factory as you are unclear of what exact type of objects you require.

If you just want to run a function for testing purposes, you can use the Immediate Window in Access.

Press Ctrl + G in the VBA editor to open it.

Then you can run your functions like this:

• ?YourFunction("parameter")
  (for functions with a return value - the return value is displayed in the Immediate Window)
• YourSub "parameter"
  (for subs without a return value, or for functions when you don't care about the return value)
• ?variable
  (to display the value of a variable)

cmsjr had the right solution. I just wanted to point out a couple of things for your future trigger development. If you are using the values statement in an insert in a trigger, there is a stong possibility that you are doing the wrong thing. Triggers fire once for each batch of records inserted, deleted, or updated. So if ten records were inserted in one batch, then the trigger fires once. If you are refering to the data in the inserted or deleted and using variables and the values clause then you are only going to get the data for one of those records. This causes data integrity problems. You can fix this by using a set-based insert as cmsjr shows above or by using a cursor. Don't ever choose the cursor path. A cursor in a trigger is a problem waiting to happen as they are slow and may well lock up your table for hours. I removed a cursor from a trigger once and improved an import process from 40 minutes to 45 seconds.

You may think nobody is ever going to add multiple records, but it happens more frequently than most non-database people realize. Don't write a trigger that will not work under all the possible insert, update, delete conditions. Nobody is going to use the one record at a time method when they have to import 1,000,000 sales target records from a new customer or update all the prices by 10% or delete all the records from a vendor whose products you don't sell anymore.

Here is another script that does what all the other scripts do. In fact, it provides a function for your shell.

Its contribution is that it pulls some colours from your Git configuration (or uses defaults).

# Git Branch by Date
# Usage: gbd [ -r ]
gbd() {
    local reset_color=`tput sgr0`
    local subject_color=`tput setaf 4 ; tput bold`
    local author_color=`tput setaf 6`

    local target=refs/heads
    local branch_color=`git config --get-color color.branch.local white`

    if [ "$1" = -r ]
    then
        target=refs/remotes/origin
        branch_color=`git config --get-color color.branch.remote red`
    fi

    git for-each-ref --sort=committerdate $target --format="${branch_color}%(refname:short)${reset_color} ${subject_color}%(subject)${reset_color} ${author_color}- %(authorname) (%(committerdate:relative))${reset_color}"
}

1) To redirect to the login page / from the login page, don't use the Redirect() methods. Use FormsAuthentication.RedirectToLoginPage() and FormsAuthentication.RedirectFromLoginPage() !

2) You should just use RedirectToAction("action", "controller") in regular scenarios.. You want to redirect in side the Initialize method? Why? I don't see why would you ever want to do this, and in most cases you should review your approach imo.. If you want to do this for authentication this is DEFINITELY the wrong way (with very little chances foe an exception) Use the [Authorize] attribute on your controller or method instead :)

UPD: if you have some security checks in the Initialise method, and the user doesn't have access to this method, you can do a couple of things: a)

Response.StatusCode = 403;
Response.End();

This will send the user back to the login page. If you want to send him to a custom location, you can do something like this (cautios: pseudocode)

Response.Redirect(Url.Action("action", "controller"));

No need to specify the full url. This should be enough. If you completely insist on the full url:

Response.Redirect(new Uri(Request.Url, Url.Action("action", "controller")).ToString());

Try this

{{ Request::segment(1) }}

You could create a list of Object like List<Object> list = new ArrayList<Object>(). As all classes implementation extends implicit or explicit from java.lang.Object class, this list can hold any object, including instances of Employee, Integer, String etc.

When you retrieve an element from this list, you will be retrieving an Object and no longer an Employee, meaning you need to perform a explicit cast in this case as follows:

List<Object> list = new ArrayList<Object>();
list.add("String");
list.add(Integer.valueOf(1));
list.add(new Employee());

Object retrievedObject = list.get(2);
Employee employee = (Employee)list.get(2); // explicit cast

Dev C++ is also a nice IDE. It's not so user friendly, but it's usefull.

As far as I remember, in the current JDBC, Resultsets and statements implement the AutoCloseable interface. That means they are closed automatically upon being destroyed or going out of scope.

Use Ctrl + / for single line comment and
Ctrl + Alt + / for block or multiline comments.

I had the same problem and I fixed it just by setting this: <item name="android:windowIsFloating">false</item> in styles.xml

An alternative would be to place the persons in a map using the name as a key:

persons.collect(Collectors.toMap(Person::getName, p -> p, (p, q) -> p)).values();

Note that the Person that is kept, in case of a duplicate name, will be the first encontered.

Adding to @jondavidjohn's answer, we can also set it as a bookmark with URL as the javascript code.

Name: Include Jquery

Url:

javascript:var jq = document.createElement('script');jq.src = "//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js";document.getElementsByTagName('head')[0].appendChild(jq); setTimeout(function() {jQuery.noConflict(); console.log('jQuery loaded'); }, 1000);void(0);

and then add it to the toolbar of Chrome or Firefox so that instead of pasting the script again and again, we can just click on the bookmarklet.

In your ASP.NET page:

<asp:Label ID="UserNameLabel" runat="server" />

In your code behind (assuming you're using C#):

function Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
       UserNameLabel.Text = "User Name";
    }
}

I don't know why this has not been included yet, but I had to do the research and find this out for myself, so hopefully someone will find this answer and be saved the trouble. This was for a WPF app. It worked fine on my Dev box, but did not work on the computer where I was copying it and got the Unable to load DLL 'SQLite.Interop.dll' error. I ported over all of its associated directories and files, directly from my "Debug" folder to this other computer when I got the same error as the OP when I ran it. My "bin" folder that contained my DLLs had been copied to "Debug\bin" and all were included, along with my application files when I did my copying to the other computer using this path, so it was not missing any files.

Things I saw said in other answers that did not apply:

• I did not use the NuGet package or need to create x86 or x64 folders that it seems that NuGet package creates. My DLLs (System.Data.SQLite and SQLite.Interop.dll, along with System.Data.SQLite.config) are in the "bin" folder in my project and were copied in manually (create "bin" folder in Solution Explorer in VS, paste DLLs into this folder in Windows Explorer, use Add > Existing Item to bring files into VS folder/project). Then I reference them as Referenced Assemblies in my project using that location ("References" > "Add Reference", and browse to one, rinse, repeat for the rest). This ensures my project knows exactly where they are.
• I did not need to reference any SQLite DLL file in my app.config or even touch my MyProject.csproj file.
• I did not even need to specify a particular processor! My project's build is for "Any CPU", even though I have only mixed or 64-bit DLLs and will only be running on Windows 7+, which are 64-bit OSes. (no x86-only/32-bit solely DLLs)
• I was already specifying them as "Content" and "copy if newer" for these DLLs when I experienced the OP's error.

What I found was this, from https://system.data.sqlite.org/index.html/doc/trunk/www/faq.wiki#q20 :

(11) Why do I get a DllNotFoundException (for "sqlite3.dll" or "SQLite.Interop.dll") when trying to run my application?

Either the named dynamic link library (DLL) cannot be located or it cannot be loaded due to missing dependencies. Make sure the named dynamic link library is located in the application directory or a directory along the system PATH and try again. Also, be sure the necessary Visual C++ runtime redistributable has been installed unless you are using a dynamic link library that was built statically linked to it.

Emphasis mine on that bolded part inside the paragraph. The target computer was fresh and had no programs loaded except .NET 4.0. Once I installed C++, it was able to complete the commands to SQLite. This should have been one of the first FAQs and part of the pre-requisities, but it was buried at #11. My development computer already had it loaded because it came with Visual Studio, so that's why it worked, there.

Use a for loop and set each one in turn.

Notes:

• xiaobai's answer is simpler (git1.7.6+): git status --ignored
  (as detailed in "Is there a way to tell git-status to ignore the effects of .gitignore files?")
• MattDiPasquale's answer (to be upvoted) git clean -ndX works on older gits, displaying a preview of what ignored files could be removed (without removing anything)

Also interesting (mentioned in qwertymk's answer), you can also use the git check-ignore -v command, at least on Unix (doesn't work in a CMD Windows session)

git check-ignore *
git check-ignore -v *

The second one displays the actual rule of the .gitignore which makes a file to be ignored in your git repo.
On Unix, using "What expands to all files in current directory recursively?" and a bash4+:

git check-ignore **/*

(or a find -exec command)

Note: https://stackoverflow.com/users/351947/Rafi B. suggests in the comments to avoid the (risky) globstar:

git check-ignore -v $(find . -type f -print)

Make sure to exclude the files from the .git/ subfolder though.

Original answer 42009)

git ls-files -i

should work, except its source code indicates:

if (show_ignored && !exc_given) {
                fprintf(stderr, "%s: --ignored needs some exclude pattern\n",
                        argv[0]);

exc_given ?

It turns out it need one more parameter after the -i to actually list anything:

Try:

git ls-files -i --exclude-from=[Path_To_Your_Global].gitignore

(but that would only list your cached (non-ignored) object, with a filter, so that is not quite what you want)

Example:

$ cat .git/ignore
# ignore objects and archives, anywhere in the tree.

$ cat Documentation/.gitignore
# ignore generated html files,

# except foo.html which is maintained by hand
!foo.html
$ git ls-files --ignored \
    --exclude='Documentation/*.[0-9]' \
    --exclude-from=.git/ignore \
    --exclude-per-directory=.gitignore

Actually, in my 'gitignore' file (called 'exclude'), I find a command line that could help you:

F:\prog\git\test\.git\info>type exclude
# git ls-files --others --exclude-from=.git/info/exclude
# Lines that start with '#' are comments.
# For a project mostly in C, the following would be a good set of
# exclude patterns (uncomment them if you want to use them):
# *.[oa]
# *~

So....

git ls-files --ignored --exclude-from=.git/info/exclude
git ls-files -i --exclude-from=.git/info/exclude

git ls-files --others --ignored --exclude-standard
git ls-files -o -i --exclude-standard

should do the trick.

(Thanks to honzajde pointing out in the comments that git ls-files -o -i --exclude-from... does not include cached files: only git ls-files -i --exclude-from... (without -o) does.)

As mentioned in the ls-files man page, --others is the important part, in order to show you non-cached, non-committed, normally-ignored files.

--exclude_standard is not just a shortcut, but a way to include all standard "ignored patterns" settings.

exclude-standard
Add the standard git exclusions: .git/info/exclude, .gitignore in each directory, and the user's global exclusion file.

To change the editor in Landscape and Vertical mode, follow the steps below.

1. For example, open two files that you have in your left or right side bar, depending on where you are placed. By default it is always on the left.

2. Now that you have both windows open, you have to use the key combination for PC (Alt + Shift + 1) for (Windows and Linux Operating Systems) or for MAC (Cmd + Option + 1), as commented here v-andrew.

I'm not sure it's possible "out of the box". And, unfortunately, I don't know an appropriate plugin either. To solve the problem you suggested you could use regular expressions.

1. Cmd + F (Find)
2. Regexp: [^ ]+ (or \d+, or whatever you prefer)
3. Option + F (Find All)
4. Edit it

Hotkeys may vary depending on you OS and personal preferences (mine are for OS X).

The error you gave is due to the fact that in python, dictionary keys must be immutable types (if key can change, there will be problems), and list is a mutable type.

Your error says that you try to use a list as dictionary key, you'll have to change your list into tuples if you want to put them as keys in your dictionary.

According to the python doc :

The only types of values not acceptable as keys are values containing lists or dictionaries or other mutable types that are compared by value rather than by object identity, the reason being that the efficient implementation of dictionaries requires a key’s hash value to remain constant

The previous posters made a little mistake. The accept attribute is only a display filter. It will not validate your entry before submitting.

This attribute forces the file dialog to display the required mime type only. But the user can override that filter. He can choose . and see all the files in the current directory. By doing so, he can select any file with any extension, and submit the form.

So, to answer to the original poster, NO. You cannot restrict the input file to one particular extension by using HTML.

But you can use javascript to test the filename that has been chosen, just before submitting. Just insert an onclick attribute on your submit button and call the code that will test the input file value. If the extension is forbidden, you'll have to return false to invalidate the form. You may even use a jQuery custom validator and so on, to validate the form.

Finally, you'll have to test the extension on the server side too. Same problem about the maximum allowed file size.

Access requires parentheses in the FROM clause for queries which include more than one join. Try it this way ...

FROM
    ((tbl_employee
    INNER JOIN tbl_netpay
    ON tbl_employee.emp_id = tbl_netpay.emp_id)
    INNER JOIN tbl_gross
    ON tbl_employee.emp_id = tbl_gross.emp_ID)
    INNER JOIN tbl_tax
    ON tbl_employee.emp_id = tbl_tax.emp_ID;

If possible, use the Access query designer to set up your joins. The designer will add parentheses as required to keep the db engine happy.

I apologize for resurecting this old thread, but I just wanted to let everyone know there is a very close Bootstrap like CSS framework specifically created for email styling, here is the link: http://zurb.com/ink/

Hope it helps someone.

Ninja edit: It has since been renamed to Foundation for Emails and the new link is: https://foundation.zurb.com/emails.html

Silent but deadly edit: New link https://get.foundation/emails.html

The general idea behind creating "optional arguments" is to first define an intermediate command that scans ahead to detect what characters are coming up next in the token stream and then inserts the relevant macros to process the argument(s) coming up as appropriate. This can be quite tedious (although not difficult) using generic TeX programming. LaTeX's \@ifnextchar is quite useful for such things.

The best answer for your question is to use the new xparse package. It is part of the LaTeX3 programming suite and contains extensive features for defining commands with quite arbitrary optional arguments.

In your example you have a \sec macro that either takes one or two braced arguments. This would be implemented using xparse with the following:

\documentclass{article}
\usepackage{xparse}
\begin{document}
\DeclareDocumentCommand\sec{ m g }{%
    {#1%
        \IfNoValueF {#2} { and #2}%
    }%
}
(\sec{Hello})
(\sec{Hello}{Hi})
\end{document}

The argument { m g } defines the arguments of \sec; m means "mandatory argument" and g is "optional braced argument". \IfNoValue(T)(F) can then be used to check whether the second argument was indeed present or not. See the documentation for the other types of optional arguments that are allowed.

I found a solution for how to set a global variable in a mailinglist posting via assign:

a <- "old"
test <- function () {
   assign("a", "new", envir = .GlobalEnv)
}
test()
a  # display the new value

upgrade numpy to the latest version

pip install numpy --upgrade

You have to look how this is called:

someObject.equals(someOtherObj); 

This invokes the equals method on the instance of someObject. Now, inside that method:

public boolean equals(Object obj) {   if (obj == this) { //is someObject equal to obj, which in this case is someOtherObj?     return true;//If so, these are the same objects, and return true   } 

You can see that this is referring to the instance of the object that equals is called on. Note that equals() is non-static, and so must be called only on objects that have been instantiated.

Note that == is only checking to see if there is referential equality; that is, the reference of this and obj are pointing to the same place in memory. Such references are naturally equal:

Object a = new Object(); Object b = a; //sets the reference to b to point to the same place as a Object c = a; //same with c b.equals(c);//true, because everything is pointing to the same place 

Further note that equals() is generally used to also determine value equality. Thus, even if the object references are pointing to different places, it will check the internals to determine if those objects are the same:

FancyNumber a = new FancyNumber(2);//Internally, I set a field to 2 FancyNumber b = new FancyNumber(2);//Internally, I set a field to 2 a.equals(b);//true, because we define two FancyNumber objects to be equal if their internal field is set to the same thing.

java_home environment variable should point to the location of the proper version of java installation directory, so that tomcat starts with the right version. for example it you built the project with java 1.7 , then make sure that JAVA_HOME environment variable points to the jdk 1.7 installation directory in your machine.

I had same problem , when i deploy the war in tomcat and run, the link throws the error. But pointing the variable - JAVA_HOME to jdk 1.7 resolved the issue, as my war file was built in java 1.7 environment.

There are at least three places where you may find shared_ptr:

1. If your C++ implementation supports C++11 (or at least the C++11 shared_ptr), then std::shared_ptr will be defined in <memory>.

2. If your C++ implementation supports the C++ TR1 library extensions, then std::tr1::shared_ptr will likely be in <memory> (Microsoft Visual C++) or <tr1/memory> (g++'s libstdc++). Boost also provides a TR1 implementation that you can use.

3. Otherwise, you can obtain the Boost libraries and use boost::shared_ptr, which can be found in <boost/shared_ptr.hpp>.

In my case, I ran git status, and I saw that I had a few untracked files in my working directory.

To make the rebase work, I just had to clean them (since I didn't need them).

To add that using Jquery:

$('#commentForm').submit(function(){ //listen for submit event
    $.each(params, function(i,param){
        $('<input />').attr('type', 'hidden')
            .attr('name', param.name)
            .attr('value', param.value)
            .appendTo('#commentForm');
    });

    return true;
}); 

Yes. Empty or incomplete headers or response body typically caused by broken connections or server side crash can cause 502 errors if accessed via a gateway or proxy.

For any object array with header and data.jsfiddle

https://jsfiddle.net/AmrendraKumar/9ac75Lg0/2/

<table id="myTable" border='1|1'></table>

<script>
  const userObjectArray = [{
    name: "Ajay",
    age: 27,
    height: 5.10,
    address: "Bangalore"
  }, {
    name: "Vijay",

  const headers = Object.keys(userObjectArray[0]);
  var tr1 = document.createElement('tr');
  var htmlHeaderStr = '';
  for (let i = 0; i < headers.length; i++) {
    htmlHeaderStr += "<th>" + headers[i] + "</th>"

Cast your TabPage to a Control, then set the Enabled property to false.

((Control)this.tabPage).Enabled = false;

Therefore, the tabpage's header will still be enabled but its contents will be disabled.

If you have a Replicated table, you can have an Identity=1000 in localDatabase and Identity=2000 in the clientDatabase, so if you catch the last ID you may find always the last from client, not the last from the current connected database. So the best method which returns the last connected database is:

SELECT IDENT_CURRENT('tablename')

On Windows 8.1 I had to run cmd.exe as administrator (even though I was logged in as admin). Otherwise I got an error when trying to execute: httpd.exe -k uninstall

Error: C:\Program Files\Apache\bin>(OS 5)Access is denied. : AH00373: Apache2.4: OpenS ervice failed

Follow below steps:

1. Open the file .bashrc which is found in location C:\Users\USERNAME\.bashrc

   If file .bashrc not exist then create it using below steps:
   

   1. Open Command Prompt and goto C:\Users\USERNAME\.
   2. Type command notepad ~/.bashrc
      It generates the .bashrc file.

2. Add below sample commands of WP CLI, Git, Grunt & PHPCS etc.

# ----------------------
# Git Command Aliases
# ----------------------
alias ga='git add'
alias gaa='git add .'
alias gaaa='git add --all'

# ----------------------
# WP CLI
# ----------------------
alias wpthl='wp theme list'
alias wppll='wp plugin list'

Now you can use the commands:

• ga instead of git add .
• wpthl instead of wp theme list

Eg. I have used wpthl for the WP CLI command wp theme list.

Yum@M MINGW64 /c/xampp/htdocs/dev.test
$ wpthl
+------------------------+----------+-----------+----------+
| name                   | status   | update    | version  |

| twentyfifteen          | inactive | none      | 2.0      |
| twentyfourteen         | inactive | none      | 2.2      |
| twentyseventeen        | inactive | available | 1.6      |
| twentysixteen          | inactive | none      | 1.5      |
| twentyten              | inactive | none      | 2.5      |

use as below:

<div id="getSessionStorage"></div>

For this to append anything use below code for reference:

$(document).ready(function () {
        var storageVal = sessionStorage.getItem("UserName");
        alert(storageVal);
        $("#getSessionStorage").append(storageVal);
     });

This will appear as below in html (assuming storageVal="Rishabh")

<div id="getSessionStorage">Rishabh</div>

The simplest (Non Win32) way is to add a UserForm to your VBA project (if you don't already have one) or alternatively add a reference to Microsoft Forms 2 Object Library, then from a sheet/module you can simply:

With New MSForms.DataObject
    .SetText "http://zombo.com"
    .PutInClipboard
End With

When you want to move objects between containers, you can use list::splice.

For example, a graph partitioning algorithm may have a constant number of objects recursively divided among an increasing number of containers. The objects should be initialized once and always remain at the same locations in memory. It's much faster to rearrange them by relinking than by reallocating.

Edit: as libraries prepare to implement C++0x, the general case of splicing a subsequence into a list is becoming linear complexity with the length of the sequence. This is because splice (now) needs to iterate over the sequence to count the number of elements in it. (Because the list needs to record its size.) Simply counting and re-linking the list is still faster than any alternative, and splicing an entire list or a single element are special cases with constant complexity. But, if you have long sequences to splice, you might have to dig around for a better, old-fashioned, non-compliant container.

Google recommends to use hreflang, read more info

Examples:

<link rel="alternate" href="http://example.com/en-ie" hreflang="en-ie" />
<link rel="alternate" href="http://example.com/en-ca" hreflang="en-ca" />
<link rel="alternate" href="http://example.com/en-au" hreflang="en-au" />
<link rel="alternate" href="http://example.com/en" hreflang="en" />

The answer shared by @mockinterface is correct. Although I would like to add my 2 cents to it.

If someone is using frameworks like scrapy the you will have to use /html/body//a[contains(@href,'com')][2]/@href along with get() like this:

response.xpath('//a[contains(@href,'com')][2]/@href').get()

You can do it with a sub-query:

SELECT * FROM (
    SELECT * FROM table ORDER BY id DESC LIMIT 50
) sub
ORDER BY id ASC

This will select the last 50 rows from table, and then order them in ascending order.

From the WooCommerce page:

// WooCommerce – display category image on category archive

add_action( 'woocommerce_archive_description', 'woocommerce_category_image', 2 );
function woocommerce_category_image() {
    if ( is_product_category() ){
      global $wp_query;
      $cat = $wp_query->get_queried_object();
      $thumbnail_id = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true );
      $image = wp_get_attachment_url( $thumbnail_id );
      if ( $image ) {
          echo '<img src="' . $image . '" alt="" />';
      }
  }
}

Here is example with only CSS for that. In example I'm using SASS and SLIM.

Cookies are Client-side and cannot be tested properly using PHP. That's the baseline and every solution is a wrap-around for this problem.

Meaning if you are looking a solution for your cookie problem, you are on the wrong way. Don'y use PHP, use a client language like Javascript.

Can you use cookies using PHP? Yes, but you have to reload to make the settings to PHP 'visible'.

For instance: Is a test possible to see if the browser can set Cookies with plain PHP'. The only correct answer is 'NO'.

Can you read an already set Cookie: 'YES' use the predefined $_COOKIE (A copy of the settings before you started PHP-App).

Just a supplement here.

The following question is that what if I want more subplots in the figure?

As mentioned in the Doc, we can use fig = plt.subplots(nrows=2, ncols=2) to set a group of subplots with grid(2,2) in one figure object.

Then as we know, the fig, ax = plt.subplots() returns a tuple, let's try fig, ax1, ax2, ax3, ax4 = plt.subplots(nrows=2, ncols=2) firstly.

ValueError: not enough values to unpack (expected 4, got 2)

It raises a error, but no worry, because we now see that plt.subplots() actually returns a tuple with two elements. The 1st one must be a figure object, and the other one should be a group of subplots objects.

So let's try this again:

fig, [[ax1, ax2], [ax3, ax4]] = plt.subplots(nrows=2, ncols=2)

and check the type:

type(fig) #<class 'matplotlib.figure.Figure'>
type(ax1) #<class 'matplotlib.axes._subplots.AxesSubplot'>

Of course, if you use parameters as (nrows=1, ncols=4), then the format should be:

fig, [ax1, ax2, ax3, ax4] = plt.subplots(nrows=1, ncols=4)

So just remember to keep the construction of the list as the same as the subplots grid we set in the figure.

Hope this would be helpful for you.

NOTICE: pay attention to the url, it's optional and it can be nil. You can wrap your url in the quote to convert it to a string. You can test it in the playground.
Update for Swift 5, Xcode 11:

import Foundation

let urlString = "http://ifconfig.me"
// string to url
let url = URL(string: urlString)
//url to string
let string = "\(url)"
// if you want the path without `file` schema
// let string = "\(url.path)"

try: #python3
    from urllib.request import urlopen
except: #python2
    from urllib2 import urlopen

When you read() the file, you may get a newline character '\n' in your string. Try either

if UserInput.strip() == 'List contents': 

or

if 'List contents' in UserInput: 

Also note that your second file open could also use with:

with open('/Users/.../USER_INPUT.txt', 'w+') as UserInputFile:     if UserInput.strip() == 'List contents': # or if s in f:         UserInputFile.write("ls")     else:         print "Didn't work" 

function invertSign($value)
{
    return -$value;
}

You need to use:

await client.PostAsync(uri, content);

Something like that:

var comment = "hello world";
var questionId = 1;

var formContent = new FormUrlEncodedContent(new[]
{
    new KeyValuePair<string, string>("comment", comment), 
    new KeyValuePair<string, string>("questionId", questionId) 
});

var myHttpClient = new HttpClient();
var response = await myHttpClient.PostAsync(uri.ToString(), formContent);

And if you need to get the response after post, you should use:

var stringContent = await response.Content.ReadAsStringAsync();

Hope it helps ;)

What about this:

<set name="fieldName" cascade="all"> 
   <key column="id" not-null="true" />
   <one-to-many class="com.yourClass"/>
</set>

I hope it helps you.

Rename the id of your ListView like this,

<ListView android:id="@android:id/list"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

Since you are using ListActivity your xml file must specify the keyword android while mentioning to a ID.

If you need a custom ListView then instead of Extending a ListActivity, you have to simply extend an Activity and should have the same id without the keyword android.

There is a package random_word could implement this request very conveniently:

 $ pip install random-word

from random_word import RandomWords
r = RandomWords()

# Return a single random word
r.get_random_word()
# Return list of Random words
r.get_random_words()
# Return Word of the day
r.word_of_the_day()

You need to use a hashbang. Add it to the first line of your python script.

#! <full path of python interpreter>

Then change the file permissions, and add the executing permission.

chmod +x <filename>

And finally execute it using

./<filename>

If its in the current directory,

The Mike R's solution works for me. This is the full set of commands:

Xvfb :99 -ac -screen 0 1280x1024x24 &
export DISPLAY=:99
nice -n 10 x11vnc 2>&1 &

Later you can run google-chrome:

google-chrome --no-sandbox &

Or start google chrome via selenium driver (for example):

ng e2e --serve true --port 4200 --watch true

Protractor.conf file:

capabilities: {
    'browserName': 'chrome',
    'chromeOptions': {
        'args': ['no-sandbox']
    }
},

You can use the below code to submit the form using JavaScript:

document.getElementById('FormID').submit();

jQuery

$(function() {
    $("td[colspan=3]").find("div").hide();
    $("tr").click(function(event) {
        var $target = $(event.target);
        $target.closest("tr").next().find("div").slideToggle();                
    });
});

                </div>
            </td>
        </tr>
    </tbody>
</table>

This is much like a previous example above. I found when trying to implement that example that if the table row to be expanded was clicked while it was not expanded it would disappear, and it would no longer be expandable

To fix that I simply removed the ability to click the expandable element for slide up and made it so that you can only toggle using the above table row.

I also made some minor changes to HTML and corresponding jQuery.

NOTE: I would have just made a comment but am not allowed to yet therefore the long post. Just wanted to post this as it took me a bit to figure out what was happening to the disappearing table row.

Here are some examples of how to use Shell in VBA.
Open stackoverflow in Chrome.

Call Shell("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" & _
 " -url" & " " & "www.stackoverflow.com",vbMaximizedFocus)

Open some text file.

Call Shell ("notepad C:\Users\user\Desktop\temp\TEST.txt")

Open some application.

Call Shell("C:\Temp\TestApplication.exe",vbNormalFocus)

Hope this helps!

Size of array cannot be modified. If you have to use an array, you can use:

System.arraycopy(src, srcpos, dest, destpos, length); 

In regards to deleting the symbolic links, I found this to be useful.

find /usr/local/bin -lname '../../../Library/Frameworks/Python.framework/Versions/2.7/*' -delete

I had the same problem with three projects in one solution and all of the suggestions didn't work until I made a reference in the reference file of the web site project to the project where the edmx file sits.

You can use Drawable instead of Uri.

   ImageView iv=(ImageView)findViewById(R.id.imageView1);
   String pathName = "/external/images/media/470939"; 
   Drawable image = Drawable.createFromPath(pathName);
   iv.setImageDrawable(image);

This would work.

Easiest way my friends, is to open the server explorer tab on visual studio 2019 (in my case), and then try to create the connection to the database. After creating a succesful connection just right click on it and go to propierties. There you will find a string connection field with the correct syntax!...This worked for me because I knew my server's name before hand....just couldn't figure out the correct syntax to run my ef scaffold...

After a long nightmare of fiddling with Google and trying out the wrong code in Stack Overflow I discovered changing ([FromBody] string model) to ([FromBody] object model) does wonders please not i am using .NET 4.0 yes yes i know it s old but ...

Go Playground http://play.golang.org/p/DN5Py5MxaB

package main

import (
    "fmt"
    "time"
)

func main() {
    t := time.Now()
    // The Time type implements the Stringer interface -- it
    // has a String() method which gets called automatically by
    // functions like Printf().
    fmt.Printf("%s\n", t)

    // See the Constants section for more formats
    // http://golang.org/pkg/time/#Time.Format
    formatedTime := t.Format(time.RFC1123)
    fmt.Println(formatedTime)
}

Use readline.get_current_history_length() to get the length, and readline.get_history_item() to view each.

For functional components try useEffect with props.location.

import React, {useEffect} from 'react';

const SampleComponent = (props) => {

      useEffect(() => {
        console.log(props.location);
      }, [props.location]);

}

export default SampleComponent;

You do not need any external command at all, just use Parameter Expansion in bash:

hostname=aaa0.bbb.ccc
echo ${hostname%%.*}

Array to stdClass can be done in php this way. (stdClass is already PHP's generic empty class)

$a = stdClass:: __set_state(array());

Actually calling stdClass::__set_state() in PHP 5 will produce a fatal error. thanks @Ozzy for pointing out

This is an example of how you can use __set_state() with a stdClass object in PHP5

class stdClassHelper{

    public static function __set_state(array $array){
        $stdClass = new stdClass();
        foreach ($array as $key => $value){
           $stdClass->$key = $value;
        }
        return $stdClass;
    }
}

$newstd = stdClassHelper::__set_state(array());

Or a nicer way.

$a = (object) array();

Swift 3

All you have to do is enable these two functions:

func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {

    return true

}

func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {

    if editingStyle == UITableViewCellEditingStyle.delete {
        tableView.reloadData()
    }

}

You're thinking too DOM, it's a hard as hell habit to break. Vue recommends you approach it data first.

It's kind of hard to tell in your exact situation but I'd probably use a v-for and make an array of finds to push to as I need more.

Here's how I'd set up my instance:

new Vue({
  el: '#app',
  data: {
    finds: []
  },
  methods: {
    addFind: function () {
      this.finds.push({ value: '' });
    }
  }
});

And here's how I'd set up my template:

<div id="app">
  <h1>Finds</h1>
  <div v-for="(find, index) in finds">
    <input v-model="find.value" :key="index">
  </div>
  <button @click="addFind">
    New Find
  </button>
</div>

Although, I'd try to use something besides an index for the key.

Here's a demo of the above: https://jsfiddle.net/crswll/24txy506/9/

Try indexing (so you want a generic solution not only for this, so index order can be just what you want):

l=[0,2,1] # index order
frame=frame[[frame.columns[i] for i in l]]

Now:

print(frame)

Is:

   one thing second thing  other thing
0          1           0.1           a
1          2           0.2           e
2          3           1.0           i
3          4           2.0           o

Another solution (but it requires jQueryUI as pointed out by Richard Neil Ilagan in comments) :-

addClass, removeClass and toggleClass also accepts a second argument; the time duration to go from one state to the other.

$(this).addClass('abc',1000);

See jsfiddle:- http://jsfiddle.net/6hvZT/1/

See the docs for to_dict. You can use it like this:

df.set_index('id').to_dict()

And if you have only one column, to avoid the column name is also a level in the dict (actually, in this case you use the Series.to_dict()):

df.set_index('id')['value'].to_dict()

To put it simply:

> var a = 1
undefined
> a.__proto__
[Number: 0]
> Number.prototype
[Number: 0]
> Number.prototype === a.__proto__
true

This allows you to attach properties to X.prototype AFTER objects of type X has been instantiated, and they will still get access to those new properties through the __proto__ reference which the Javascript-engine uses to walk up the prototype chain.

Try this,

IFS=''
while read line
do
    echo $line
done < file.txt

EDIT:

From man bash

IFS - The Internal Field Separator that is used for word
splitting after expansion and to split lines into words
with  the  read  builtin  command. The default value is
``<space><tab><newline>''

1. User.destroy

User.destroy(1) will delete user with id == 1 and :before_destroy and :after_destroy callbacks occur. For example if you have associated records

has_many :addresses, :dependent => :destroy

After user is destroyed his addresses will be destroyed too. If you use delete action instead, callbacks will not occur.

2. User.destroy, User.delete

3. User.destroy_all(<conditions>) or User.delete_all(<conditions>)

Notice: User is a class and user is an instance object

public boolean checkForEmail() {
        Context c;
        EditText mEtEmail=(EditText)findViewById(R.id.etEmail);
        String mStrEmail = mEtEmail.getText().toString();
        if (android.util.Patterns.EMAIL_ADDRESS.matcher(mStrEmail).matches()) {
            return true;
        }
        Toast.makeText(this,"Email is not valid", Toast.LENGTH_LONG).show();
        return false;
    }


    public boolean checkForMobile() {
        Context c;
        EditText mEtMobile=(EditText)findViewById(R.id.etMobile);
        String mStrMobile = mEtMobile.getText().toString();
        if (android.util.Patterns.PHONE.matcher(mStrMobile).matches()) {
            return true;
        }
        Toast.makeText(this,"Phone No is not valid", Toast.LENGTH_LONG).show();
        return false;
    }

A previous answer using LPAD() is optimal. However, in the event you want to do special or advanced processing, here is a method that allows more iterative control over the padding. Also serves as an example using other constructs to achieve the same thing.

UPDATE
    mytable
SET
    mycolumn = CONCAT(
        REPEAT(
            "0",
            8 - LENGTH(mycolumn)
        ),
        mycolumn
    )
WHERE
    LENGTH(mycolumn) < 8;

On my Ubuntu machine, I can see the output at /var/log/syslog.

On a RHEL/CentOS machine, the output is found in /var/log/messages.

This is controlled by the rsyslog service, so if this is disabled for some reason you may need to start it with systemctl start rsyslog.

As noted by others, your syslog() output would be logged by the /var/log/syslog file.
You can see system, user, and other logs at /var/log.

In HTML body try:

<table>
    <tr>
        <td>
            <div style="word-wrap: break-word; width: 800px">
                Hello world, how are you? More text here to see if it wraps after a long while of writing and it does on Firefox but I have not tested it on Chrome yet. It also works wonders if you have a medium to long paragraph. Just avoid writing in the CSS file that the words have to break-all, that's a small tip.
            </div>
        </td>
    </tr>
</table>

In CSS body try:

table-layout: fixed;

Use the same file.sh

Build the image using the existing Dockerfile:

docker build -t test .

Run the image with arguments abc or xyz or something else.

docker run -ti --rm test /file.sh abc

docker run -ti --rm test /file.sh xyz

The default solution is to install KB2999226 of Microsoft.

Yes, you can detect if the session is already running by checking isset($_SESSION). However the best answer is simply not to call session_start() more than once.

It should be called very early in your script, possibly even the first line, and then not called again.

If you have it in more than one place in your code then you're asking to get this kind of bug. Cut it down so it's only in one place and can only be called once.

If your code can sensibly be written as a case statement, this is pretty decent:

case mybool
when TrueClass, FalseClass
  puts "It's a bool!"
else
  puts "It's something else!"
end

Wrap your floating <div>s in a container <div> that uses this cross-browser min-width hack:

.minwidth { min-width:100px; width: auto !important; width: 100px; }

You may also need to set "overflow" but probably not.

This works because:

• The !important declaration, combined with min-width cause everything to stay on the same line in IE7+
• IE6 does not implement min-width, but it has a bug such that width: 100px overrides the !important declaration, causing the container width to be 100px.

On Ubuntu after installing lxc-docker you need to add your user to the docker user group:

sudo usermod -a -G docker myusername

This is because of the socket file permissions:

srw-rw---- 1 root docker 0 Mar 20 07:43 /var/run/docker.sock

DO NOT RUN usermod WITHOUT "-a" as suggested in one of the other comments or it will wipe your additional groups setting and will just leave the "docker" group

This is what will happen:

?  ~  id pawel
uid=1000(pawel) gid=1000(pawel) groups=1000(pawel),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),108(lpadmin),124(sambashare),998(docker)
?  ~  usermod -G docker pawel
?  ~  id pawel               
uid=1000(pawel) gid=1000(pawel) groups=1000(pawel),998(docker)

you can set this in catalina.sh as CATALINA_OPTS=-Xms512m -Xmx512m

Open your tomcat-dir/bin/catalina.sh file and add following line anywhere -

CATALINA_OPTS="$CATALINA_OPTS -Xms1024m -Xmx3024m"

and restart your tomcat

when I try to run it, I get NoClassDefFoundError

Run it how? You're probably trying to run it with eclipse without having correctly imported your maven classpath. See the m2eclipse plugin for integrating maven with eclipse for that.

To verify that your maven config is correct, you could run your app with the exec plugin using:

mvn exec:java -D exec.mainClass=<your main class>

Update: First, regarding your error when running exec:java, your main class is tr.edu.hacettepe.cs.b21127113.bil138_4.App. When talking about class names, they're (almost) always dot-separated. The simple class name is just the last part: App in your case. The fully-qualified name is the full package plus the simple class name, and that's what you give to maven or java when you want to run something. What you were trying to use was a file system path to a source file. That's an entirely different beast. A class name generally translates directly to a class file that's found in the class path, as compared to a source file in the file system. In your specific case, the class file in question would probably be at target/classes/tr/edu/hacettepe/cs/b21127113/bil138_4/App.class because maven compiles to target/classes, and java traditionally creates a directory for each level of packaging.

Your original problem is simply that you haven't put the Jackson jars on your class path. When you run a java program from the command line, you have to set the class path to let it know where it can load classes from. You've added your own jar, but not the other required ones. Your comment makes me think you don't understand how to manually build a class path. In short, the class path can have two things: directories containing class files and jars containing class files. Directories containing jars won't work. For more details on building a class path, see "Setting the class path" and the java and javac tool documentation.

Your class path would need to be at least, and without the line feeds:

target/bil138_4-0.0.1-SNAPSHOT.jar:
/home/utdemir/.m2/repository/org/codehaus/jackson/jackson-core-asl/1.9.6/jackson-core-asl-1.9.6.jar:
/home/utdemir/.m2/repository/org/codehaus/jackson/jackson-mapper-asl/1.9.6/jackson-mapper-asl-1.9.6.jar

Note that the separator on Windows is a semicolon (;).

I apologize for not noticing it sooner. The problem was sitting there in your original post, but I missed it.

In Oracle DB:

create table temp_test1 (id number, value number, description varchar2(20));

insert into temp_test1 values(1, 22, 'qq');
insert into temp_test1 values(2, 22, 'qq');
insert into temp_test1 values(3, 22, 'qq');
insert into temp_test1 values(4, 23, 'qq1');
insert into temp_test1 values(5, 23, 'qq1');
insert into temp_test1 values(6, 23, 'qq1');

SELECT MAX(id), value, description FROM temp_test1 GROUP BY value, description;

Result:
    MAX(ID) VALUE DESCRIPTION
    -------------------------
    6         23    qq1
    3         22    qq

the proper way is:

.attr({target:'nw', title:'Opens in a new window'})

use User::get(['id', 'name', 'email']), it will return you a collection with the specified columns and if you want to make it an array, just use toArray() after the get() method like so:

User::get(['id', 'name', 'email'])->toArray()

Most of the times, you won't need to convert the collection to an array because collections are actually arrays on steroids and you have easy-to-use methods to manipulate the collection.

for i in arr1:
    if i in arr2:
        return 1
    return  0
arr1=[1,2,5]
arr2=[2,4,15]
q=checkarrayequalornot(arr1,arr2)
print(q)
>>0

Add a class:

.com_box:after {
     content: '';
    position: absolute;
    left: 18px;
    top: 50px;
    width: 0;
    height: 0;
    border-left: 20px solid transparent;
    border-right: 20px solid transparent;
    border-top: 20px solid #000;
    clear: both;

}

tl;dr Use image specified at https://docs.travis-ci.com/user/common-build-problems/#troubleshooting-locally-in-a-docker-image in combination with https://github.com/travis-ci/travis-build#use-as-addon-for-travis-cli.

#troubleshooting-locally-in-a-docker-image section was replaced by #running-builds-in-debug-mode which also describes how to SSH to the job running in the debug mode.

EDIT 2019-07-26

#troubleshooting-locally-in-a-docker-image section is no longer part of the docs; here's why

• https://github.com/travis-ci/docs-travis-ci-com/issues/2342
  • https://blog.travis-ci.com/2018-10-04-combining-linux-infrastructures
  • https://blog.travis-ci.com/2018-11-30-announcing-xenial-build-environment-for-enterprise

Though, it's still in git history: https://github.com/travis-ci/docs-travis-ci-com/pull/2193.

Look for (quite old, couldn't find newer) image versions at: https://travis-ci.org/travis-ci/docs-travis-ci-com/builds/230889063#L661.

I wanted to inspect why one of the tests in my build failed with an error I din't get locally.

Worked.

What actually worked was using the image specified at Troubleshooting Locally in a Docker Image docs page. In my case it was travisci/ci-garnet:packer-1512502276-986baf0.

I was able to add travise compile following steps described at https://github.com/travis-ci/travis-build#use-as-addon-for-travis-cli.

I might have a solution for the video as background, stretched to the browser-width or height, (but the video will still preserve the aspect ratio, couldnt find a solution for that yet.):

Put the video right after the body-tag with style="width:100%;". Right afterwords, put a "bodydummy"-tag:

<body>
<video id="bgVideo" autoplay poster="videos/poster.png">
    <source src="videos/test-h264-640x368-highqual-winff.mp4" type="video/mp4"/>
    <source src="videos/test-640x368-webmvp8-miro.webm" type="video/webm"/>
    <source src="videos/test-640x368-theora-miro.ogv" type="video/ogg"/>    
</video>

<img id="bgImg" src="videos/poster.png" />

<!-- This image stretches exactly to the browser width/height and lies behind the video-->

<div id="bodyDummy">

Put all your content inside the bodydummy-div and put the z-indexes correctly in CSS like this:

#bgImg{ 
    position: absolute;
    top: 0;
    left: 0;
    border: 0;
    z-index: 1;
    width: 100%;
    height: 100%;
}

#bgVideo{ 
    position: absolute;
    top: 0;
    left: 0;
    border: 0;
    z-index: 2;
    width: 100%;
    height: 100%;
}

#bodyDummy{ 
    position: absolute;
    top: 0;
    left: 0;
    z-index: 3;
    overflow: auto;
    width: 100%;
    height: 100%;
}

Hope I could help. Let me know when you could find a solution that the video does not maintain the aspect ratio, so it could fill the whole browser window so we do not have to put a bgimage.

val file = scala.io.Source.fromFile(s"src/main/resources/app.config").getLines().mkString

Here is what the JSF javadocs have to say about the commandButton action attribute:

MethodExpression representing the application action to invoke when this component is activated by the user. The expression must evaluate to a public method that takes no parameters, and returns an Object (the toString() of which is called to derive the logical outcome) which is passed to the NavigationHandler for this application.

It would be illuminating to me if anyone can explain what that has to do with any of the answers on this page. It seems pretty clear that action refers to some page's filename and not a method.

You can use Object.keys(), "which returns an array of a given object's own enumerable property names, in the same order as we get with a normal loop."

You can use any object in place of stats:

var stats = {_x000D_
  a: 3,_x000D_
  b: 6,_x000D_
  d: 7,_x000D_
  erijgolekngo: 35_x000D_
}_x000D_
/*  this is the answer here  */_x000D_
for (var key in Object.keys(stats)) {_x000D_
  var t = Object.keys(stats)[key];_x000D_
  console.log(t + " value =: " + stats[t]);_x000D_
}

A better way is using decorator instead of writing wrapper function by hand. Especially when you have a lot of functions to map, decorator will save your time by avoiding writing wrapper for every function. Usually a decorated function is not picklable, however we may use functools to get around it. More disscusions can be found here.

Here the example

def unpack_args(func):
    from functools import wraps
    @wraps(func)
    def wrapper(args):
        if isinstance(args, dict):
            return func(**args)
        else:
            return func(*args)
    return wrapper

@unpack_args
def func(x, y):
    return x + y

Then you may map it with zipped arguments

np, xlist, ylist = 2, range(10), range(10)
pool = Pool(np)
res = pool.map(func, zip(xlist, ylist))
pool.close()
pool.join()

Of course, you may always use Pool.starmap in Python 3 (>=3.3) as mentioned in other answers.

Maybe you should not have been making an AutoPostBack.
If your code doesn't make a PostBack, you can get this error.

Range("A10") is the answer cell

Range("A1", "A9") is the range to calculate

Qt has a method for copying files:

#include <QFile>
QFile::copy("originalFile.example","copiedFile.example");

Note that to use this you have to install Qt (instructions here) and include it in your project (if you're using Windows and you're not an administrator, you can download Qt here instead). Also see this answer.

None of the other answers were satisfying, largely because the UI still looks bad. I found this, which looks good and is very close to being perfect as well as customizable.

A full list of examples and options and such can be found here, but here's a basic demo:

$('#editable-select').editableSelect();

You Can Now Delete App.

On October 4, 2018, Apple released a new update of the appstoreconnect (previously iTunesConnect).

It's now easier to manage apps you no longer need in App Store Connect by removing them from your main view in My Apps, even if they haven't been submitted for approval. You must have the Legal or Admin role to remove apps.

From the homepage, click My Apps, then choose the app you want to remove. Scroll to the Additional Information section, then click Remove App. In the dialog that appears, click Remove. You can restore a removed app at any time, as long as the app name is not currently in use by another developer.

From the homepage, click My Apps. In the upper right-hand corner, click the arrow next to All Statuses. From the drop-down menu, choose Removed Apps. Choose the app you want to restore. Scroll to the Additional Information section, then click Restore App.

You can show the removed app by clicking on all Statuses on the top right of the screen and then select Removed Apps. Thank you @Daniel for the tips.

Please note:

you can only remove apps if all versions of that app are in one of the following states: Prepare for Submission, Invalid Binary, Developer Rejected, Rejected, Metadata Rejected, Developer, Removed from Sale.

As an alternative to rendering a raster image, you can embed a SVG file:

<a><img src="http://dump.thecybershadow.net/6c736bfd11ded8cdc5e2bda009a6694a/colortext.svg"/></a>

You can then add color text to the SVG file as usual:

<?xml version="1.0" encoding="utf-8"?>
<svg version="1.1" 
     xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink"
     width="100" height="50"
>
  <text font-size="16" x="10" y="20">
    <tspan fill="red">Hello</tspan>,
    <tspan fill="green">world</tspan>!
  </text>
</svg>

Unfortunately, even though you can select and copy text when you open the .svg file, the text is not selectable when the SVG image is embedded.

In objectMapper we have writeValueAsString() which accepts object as parameter. We can pass object list as parameter get the string back.

List<Apartment> aptList =  new ArrayList<Apartment>();
    Apartment aptmt = null;
    for(int i=0;i<5;i++){
         aptmt= new Apartment();
         aptmt.setAptName("Apartment Name : ArrowHead Ranch");
         aptmt.setAptNum("3153"+i);
         aptmt.setPhase((i+1));
         aptmt.setFloorLevel(i+2);
         aptList.add(aptmt);
    }
mapper.writeValueAsString(aptList)

The syntax for index hints is documented here:
http://dev.mysql.com/doc/refman/5.6/en/index-hints.html

FORCE INDEX goes right after the table reference:

SELECT * FROM (
    SELECT owner_id,
           product_id,
           start_time,
           price,
           currency,
           name,
           closed,
           active,
           approved,
           deleted,
           creation_in_progress
    FROM db_products FORCE INDEX (products_start_time)
    ORDER BY start_time DESC
) as resultstable
WHERE resultstable.closed = 0
      AND resultstable.active = 1
      AND resultstable.approved = 1
      AND resultstable.deleted = 0
      AND resultstable.creation_in_progress = 0
GROUP BY resultstable.owner_id
ORDER BY start_time DESC

WARNING:

If you're using ORDER BY before GROUP BY to get the latest entry per owner_id, you're using a nonstandard and undocumented behavior of MySQL to do that.

There's no guarantee that it'll continue to work in future versions of MySQL, and the query is likely to be an error in any other RDBMS.

Search the greatest-n-per-group tag for many explanations of better solutions for this type of query.

By configuring that the IDE projects are setup to use a Java 6 JRE or above sometimes does not remove the eclipse error. For me a restart of the Eclipe IDE helped.

for group headers/footers:

=iif(RunningValue(*group on field*,CountDistinct,"*parent group name*") Mod 2,"White","AliceBlue")

You can also use this to “reset” the row color count within each group. I wanted the first detail row in each sub group to start with White and this solution (when used on the detail row) allowed that to happen:

=IIF(RunningValue(Fields![Name].Value, CountDistinct, "NameOfPartnetGroup") Mod 2, "White", "Wheat")

Use execute_script, here's a python example:

from selenium import webdriver
driver = webdriver.Firefox()
driver.get("http://stackoverflow.com/questions/7794087/running-javascript-in-selenium-using-python") 
driver.execute_script("document.getElementsByClassName('comment-user')[0].click()")

I've had better luck with calling the gotoDate in the viewRender callback:

$('#calendar').fullCalendar({
  firstDay: 0,
  defaultView: 'basicWeek',
  header: {
    left: '',
    center: 'basicDay,basicWeek,month',
    right:  'today prev,next'
  },
  viewRender: function(view, element) {
    $('#calendar').fullCalendar( 'gotoDate', 2014, 4, 24 );
  }
});

Calling gotoDate outside of the callback didn't have the expected results due to a race condition.

C# supports two forms of string literals: regular string literals and verbatim string literals.

A regular string literal consists of zero or more characters enclosed in double quotes, as in "hello", and may include both simple escape sequences (such as \t for the tab character) and hexadecimal and Unicode escape sequences.

A verbatim string literal consists of an @ character followed by a double-quote character, zero or more characters, and a closing double-quote character. A simple example is @"hello". In a verbatim string literal, the characters between the delimiters are interpreted verbatim, the only exception being a quote-escape-sequence. In particular, simple escape sequences and hexadecimal and Unicode escape sequences are not processed in verbatim string literals. A verbatim string literal may span multiple lines.

parseInt always rounds down soo.....

console.log(parseInt(5.8)+1);

do parseInt()+1

Just re-posting answer by oleynikd because it's simple and neat

Bundle bundle = ActivityOptionsCompat.makeCustomAnimation(getContext(),
    android.R.anim.fade_in, android.R.anim.fade_out).toBundle(); 
startActivity(intent, bundle);

Put this code to your view controller in which you hide status bar:

- (BOOL)prefersStatusBarHidden {return YES;}

O(1) - most cooking procedures are O(1), that is, it takes a constant amount of time even if there are more people to cook for (to a degree, because you could run out of space in your pot/pans and need to split up the cooking)

O(logn) - finding something in your telephone book. Think binary search.

O(n) - reading a book, where n is the number of pages. It is the minimum amount of time it takes to read a book.

O(nlogn) - cant immediately think of something one might do everyday that is nlogn...unless you sort cards by doing merge or quick sort!

The difference between pointers and references is quite simple: a pointer can be null, a reference can not.

Examine your API, if it makes sense for null to be able to be returned, possibly to indicate an error, use a pointer, otherwise use a reference. If you do use a pointer, you should add checks to see if it's null (and such checks may slow down your code).

Here it looks like references are more appropriate.

public static void main(String[] args) throws InterruptedException {
  //type code


  short z=1000;
  Thread.sleep(z);/*will provide 1 second delay. alter data type of z or value of z for longer delays required */

  //type code
}

eg:-

class TypeCasting {

  public static void main(String[] args) throws InterruptedException {
    short f = 1;
    int a = 123687889;
    short b = 2;
    long c = 4567;
    long d=45;
    short z=1000;
    System.out.println("Value of a,b and c are\n" + a + "\n" + b + "\n" + c + "respectively");
    c = a;
    b = (short) c;
    System.out.println("Typecasting...........");
    Thread.sleep(z);
    System.out.println("Value of B after Typecasting" + b);
    System.out.println("Value of A is" + a);


  }
}

I had this problem on Windows 8, but I solved the problem by updating all of Android Studio's plugins with the SDK Manager, then restarting the computer.

It's a language abstraction - some languages have both, some one, some neither.

In the case of C++, the code is not run in either the stack or the heap. You can test what happens if you run out of heap memory by repeatingly calling new to allocate memory in a loop without calling delete to free it it. But make a system backup before doing this.

for each project in your solution make sure that
