If you want the value from cell then you don't have to recreate cell in the didSelectRowAtIndexPath

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
    println(tasks[indexPath.row])
}

Task would be as follows :

let tasks=["Short walk",
    "Audiometry",
    "Finger tapping",
    "Reaction time",
    "Spatial span memory"
]

also you have to check the cellForRowAtIndexPath you have to set identifier.

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("CellIdentifier", forIndexPath: indexPath) as UITableViewCell
    var (testName) = tasks[indexPath.row]
    cell.textLabel?.text=testName
    return cell
}

Hope it helps.

Swift 5 : For evenly distributed spaces between cells with dynamic cell width to make the best of container space you may use the code snippet below by providing a minimumCellWidth value.

private func collectionViewLayout() -> UICollectionViewLayout {
    
    let layout = UICollectionViewFlowLayout()
    layout.sectionHeadersPinToVisibleBounds = true
    // Important: if direction is horizontal use minimumItemSpacing instead. 
    layout.scrollDirection = .vertical
    
    let itemHeight: CGFloat = 240
    let minCellWidth :CGFloat = 130.0
    let minItemSpacing: CGFloat = 10
    let containerWidth: CGFloat = self.view.bounds.width
    let maxCellCountPerRow: CGFloat =  floor((containerWidth - minItemSpacing) / (minCellWidth+minItemSpacing ))
    
    let itemWidth: CGFloat = floor( ((containerWidth - (2 * minItemSpacing) - (maxCellCountPerRow-1) * minItemSpacing) / maxCellCountPerRow  ) )
    // Calculate the remaining space after substracting calculating cellWidth (Divide by 2 because of left and right insets)
    let inset = max(minItemSpacing, floor( (containerWidth - (maxCellCountPerRow*itemWidth) - (maxCellCountPerRow-1)*minItemSpacing) / 2 ) )

    
    layout.itemSize = CGSize(width: itemWidth, height: itemHeight)
    layout.minimumInteritemSpacing = min(minItemSpacing,inset)
    layout.minimumLineSpacing = minItemSpacing
    layout.sectionInset = UIEdgeInsets(top: minItemSpacing, left: inset, bottom: minItemSpacing, right: inset)

    
    return layout
}

Follow bolnad answer up to Step 4.

Then make it simpler by replacing all the other steps with:

func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {

    // Configure your cell
    sizingNibNew.configureCell(data as! CustomCellData, delegate: self)

    // We use the full width minus insets
    let width = collectionView.frame.size.width - collectionView.sectionInset.left - collectionView.sectionInset.right

    // Constrain our cell to this width 
    let height = sizingNibNew.systemLayoutSizeFitting(CGSize(width: width, height: .infinity), withHorizontalFittingPriority: UILayoutPriorityRequired, verticalFittingPriority: UILayoutPriorityFittingSizeLevel).height

    return CGSize(width: width, height: height)
}

Quick fix - make sure all variables which do not get initialized when they are created (eg var num : Int? vs var num = 5) have either a ? or !.

Long answer (reccomended) - read the doc as per mprivat suggests...

You did not register your nib as below:

tableView.registerNib(UINib(nibName: "CustomCell", bundle: nil), forCellReuseIdentifier: "CustomCell")

Nil Coalescing Operator can be used as well.

rowName = rowName != nil ?rowName!.stringFromCamelCase():""

import UIKit

class ViewController: UIViewController {
    private weak var tableView: UITableView?
    override func viewDidLoad() {
        super.viewDidLoad()
        setupTableView()
    }
}

// MARK: - Setup(init) subviews

    private func setupTableView() {
        let tableView = UITableView()
        view.addSubview(tableView)
        self.tableView = tableView

            }
        }
    }
}

Results

You have just to enter:

First a IBOutlet:

@IBOutlet var appsTableView : UITableView

Then in a Action func:

self.appsTableView.reloadData()

func tableView(_ tableView: UITableView, editActionsForRowAt: IndexPath) -> [UITableViewRowAction]? {

  let share = UITableViewRowAction(style: .normal, title: "Share") { action, index in
    //handle like delete button
    print("share button tapped")
  }

  share.backgroundColor = .lightGray

  let delete = UITableViewRowAction(style: .normal, title: "Delete") { action, index in
    self.nameArray.remove(at: editActionsForRowAt.row)
    self.swipeTable.beginUpdates()
    self.swipeTable.deleteRows(at: [editActionsForRowAt], with: .right)
    self.swipeTable.endUpdates()

    print("delete button tapped")
  }

  delete.backgroundColor = .orange
  return [share,delete]
}

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

In this thread, There are so many solutions that work fine if cell takes full screen but they use collection view bounds and midpoints of Visible rect However there is a simple solution to this problem

    DispatchQueue.main.async {
        let visibleCell = self.collImages.visibleCells.first
        print(self.collImages.indexPath(for: visibleCell))
    }

by this, you can get indexPath of the visible cell. I have added DispatchQueue because when you swipe faster and if for a brief moment the next cell is shown then without dispactchQueue you'll get indexPath of briefly shown cell not the cell that is being displayed on the screen.

The headers only remain fixed when the UITableViewStyle property of the table is set to UITableViewStylePlain. If you have it set to UITableViewStyleGrouped, the headers will scroll up with the cells.

You can just pass your URL,

NSURL *url = [NSURL URLWithString:@"http://www.myurl.com/1.png"];
NSURLSessionTask *task = [[NSURLSession sharedSession] dataTaskWithURL:url completionHandler:^(NSData * _Nullable data,    NSURLResponse * _Nullable response, NSError * _Nullable error) {
    if (data) {
        UIImage *image = [UIImage imageWithData:data];
        if (image) {
            dispatch_async(dispatch_get_main_queue(), ^{
                    yourimageview.image = image;
            });
        }
    }
}];
[task resume];

- (void)viewDidLoad {
     [super viewDidLoad];
     arr=[[NSArray alloc]initWithObjects:@"ABC",@"XYZ", nil];
     tableview = [[UITableView alloc]initWithFrame:tableFrame style:UITableViewStylePlain];   
     tableview.delegate = self;
     tableview.dataSource = self;
     [self.view addSubview:tableview];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return arr.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"MyCell"];

    if(cell == nil)
    {
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"MyCell"];
    }

    cell.textLabel.text=[arr objectAtIndex:indexPath.row];

    return cell;
}

In your storyboard you should set the 'Identifier' of your prototype cell to be the same as your CellReuseIdentifier "Cell". Then you won't get that message or need to call that registerClass: function.

SIGABRT is, as stated in other answers, a general uncaught exception. You should definitely learn a little bit more about Objective-C. The problem is probably in your UITableViewDelegate method didSelectRowAtIndexPath.

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

I can't tell you much more until you show us something of the code where you handle the table data source and delegate methods.

Subclass the button to store the required value, maybe create a protocol (ControlWithData or something). Set the value when you add the button to the table view cell. In your touch up event, see if the sender obeys the protocol and extract the data. I normally store a reference to the actual object that is rendered on the table view cell.

I saw a lot of solutions but all was wrong or uncomplet. You can solve all problems with 5 lines in viewDidLoad and autolayout. This for objetive C:

_tableView.delegate = self;
_tableView.dataSource = self;
self.tableView.estimatedRowHeight = 80;//the estimatedRowHeight but if is more this autoincremented with autolayout
self.tableView.rowHeight = UITableViewAutomaticDimension;
[self.tableView setNeedsLayout];
[self.tableView layoutIfNeeded];
self.tableView.contentInset = UIEdgeInsetsMake(20, 0, 0, 0) ;

For swift 2.0:

 self.tableView.estimatedRowHeight = 80
 self.tableView.rowHeight = UITableViewAutomaticDimension      
 self.tableView.setNeedsLayout()
 self.tableView.layoutIfNeeded()
 self.tableView.contentInset = UIEdgeInsetsMake(20, 0, 0, 0)

Now create your cell with xib or into tableview in your Storyboard With this you no need implement nothing more or override. (Don forget number os lines 0) and the bottom label (constrain) downgrade "Content Hugging Priority -- Vertical to 250"

You can donwload the code in the next url: https://github.com/jposes22/exampleTableCellCustomHeight

string_website.py

search string in webpage

    from selenium import webdriver
    from selenium.webdriver.common.keys import Keys

    result = content.find('integrate systems')
    print ("Substring found at index:", result ) 

    if (result != -1): 
    print("Webpage OK")
    else: print("Webpage NOT OK")
    #print(content)
    browser.close()

Somehow I fiddled around and some how I got it to work:

<iframe src="http://www.example.com#inside" width="100%" height="100%" align="center" ></iframe>

I think this is the first time this code has been posted so share it

Following code worked for me

The input box with "onkeypress" event as follows

<input type="text" onkeypress="return isNumberKey(this,event);" />

The function "isNumberKey" is as follows

function isNumberKey(txt, evt) {_x000D_
  var charCode = (evt.which) ? evt.which : evt.keyCode;_x000D_
  if (charCode == 46) {_x000D_
    //Check if the text already contains the . character_x000D_
    if (txt.value.indexOf('.') === -1) {_x000D_
        return true;_x000D_
    } else {_x000D_
        return false;_x000D_
    }_x000D_
  } else {_x000D_
    if (charCode > 31 && (charCode < 48 || charCode > 57))_x000D_
        return false;_x000D_
  }_x000D_
  return true;_x000D_
}

Sometimes the execution runs first time, and when we do maven clean install it doesn't generate after that. The issue was using true for skipMain and skip properties under maven-compiler-plugin of the main pom File. Remove them if they were introduced as a part of any issue or suggestion.

it is a ternary operator and in simple english it states "if row%2 is equal to 1 then return < else return /r"

Hi I think the SimpleXml is very useful . And with it I am using xpath;

$xml = simplexml_load_file("som_xml.xml");

$blocks  = $xml->xpath('//block'); //gets all <block/> tags
$blocks2 = $xml->xpath('//layout/block'); //gets all <block/> which parent are   <layout/>  tags

I use many xml configs and this helps me to parse them really fast. SimpleXml is written on C so it's very fast.

If you want a simple DD/MM/YYYY format, I've just come up with this simple solution, although it doesn't prefix missing zeros.

var d = new Date();_x000D_
document.write( [d.getDate(), d.getMonth()+1, d.getFullYear()].join('/') );

Take a look on this answer to another related question. It shows how to enable, disable and to see the logs on live servers without restarting.

Log all queries in mysql

Here is a summary:

If you don't want or cannot restart the MySQL server you can proceed like this on your running server:

• Create your log tables (see answer)

• Enable Query logging on the database (Note that the string 'table' should be put literally and not substituted by any table name. Thanks Nicholas Pickering)

SET global general_log = 1;
SET global log_output = 'table';

• View the log

select * from mysql.general_log;

• Disable Query logging on the database

SET global general_log = 0;

• Clear query logs without disabling

TRUNCATE mysql.general_log

You want to have a look at FileField and FieldFile in the Django docs, and especially FieldFile.save().

Basically, a field declared as a FileField, when accessed, gives you an instance of class FieldFile, which gives you several methods to interact with the underlying file. So, what you need to do is:

self.license_file.save(new_name, new_contents)

where new_name is the filename you wish assigned and new_contents is the content of the file. Note that new_contents must be an instance of either django.core.files.File or django.core.files.base.ContentFile (see given links to manual for the details).

The two choices boil down to:

from django.core.files.base import ContentFile, File

# Using File
with open('/path/to/file') as f:
    self.license_file.save(new_name, File(f))

# Using ContentFile
self.license_file.save(new_name, ContentFile('A string with the file content'))

"Make browser window blink in task Bar"

via Javascript 

is not possible!!

If a computer can run it, a suitably motivated human can reverse-engineer it.

Assuming you are dealing with a single class per element:

function swapCssClass(a,b) {
    while (document.querySelector('.' + a)) {
        document.querySelector('.' + a).className = b;
    }
}

and then call simply call it with

swapCssClass('x_visible','x_hidden');

You have two possibilities (for an IPv4 address) :

• a varchar(15), if your want to store the IP address as a string
  • 192.128.0.15 for instance
• an integer (4 bytes), if you convert the IP address to an integer
  • 3229614095 for the IP I used before

The second solution will require less space in the database, and is probably a better choice, even if it implies a bit of manipulations when storing and retrieving the data (converting it from/to a string).

About those manipulations, see the ip2long() and long2ip() functions, on the PHP-side, or inet_aton() and inet_ntoa() on the MySQL-side.

This is how I solved the problem:

@{int proID = 123; int nonProID = 456;}

<script type="text/javascript">
var nonID = Number(@nonProID);
var proID = Number(@proID);
</script>

It is self-documenting and it doesn't involve conversion to and from text.

Note: be careful to use the Number() function not create new Number() objects - as the exactly equals operator may behave in a non-obvious way:

var y = new Number(123); // Note incorrect usage of "new"
var x = new Number(123);
alert(y === 123); // displays false
alert(x == y); // displays false

See String Formatting Operations:

%d is the format code for an integer. %f is the format code for a float.

%s prints the str() of an object (What you see when you print(object)).

%r prints the repr() of an object (What you see when you print(repr(object)).

For a float %s, %r and %f all display the same value, but that isn't the case for all objects. The other fields of a format specifier work differently as well:

>>> print('%10.2s' % 1.123) # print as string, truncate to 2 characters in a 10-place field.
        1.
>>> print('%10.2f' % 1.123) # print as float, round to 2 decimal places in a 10-place field.
      1.12

You can try using:

textBox.ReadOnly = true;
textBox.BackColor = System.Drawing.SystemColors.Window;

The last line is only neccessary if you want a non-grey background color.

From Laravel 5.7 and date format i.e.: 12/31/2019

function checkDateFormat(string $date): bool
{
    return preg_match("/^(0[1-9]|1[0-2])\/(0[1-9]|[1-2][0-9]|3[0-1])\/[0-9]{4}$/", $date);
}

Create /res/drawable/button.xml with the following content :

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:padding="10dp">
<!-- you can use any color you want I used here gray color-->
 <solid android:color="#90EE90"/> 
    <corners
     android:bottomRightRadius="3dp"
     android:bottomLeftRadius="3dp"
  android:topLeftRadius="3dp"
  android:topRightRadius="3dp"/>
</shape>

And then you can use the following :

<Button
    android:id="@+id/button_save_prefs"
    android:text="@string/save"
    android:background="@drawable/button"/>

This sometimes can be thrown before the actual log4j2 configuration file found on the web servlet. at least for my case I think so. Cuz I already have in my web.xml

  <context-param>
    <param-name>log4jConfiguration</param-name>
    <param-value>classpath:log4j2-app.xml</param-value>
  </context-param>

and checking the log4j-web source; in class

org.apache.logging.log4j.web.Log4jWebInitializerImpl

there is the line;

String location = this.substitutor
                 .replace(this.servletContext.getInitParameter("log4jConfiguration"));

all those makes me think that this is temporary log before configuration found.

Assume you stored that dictionary in a variable called values. To get id in to a variable, do:

idValue = values['criteria'][0]['id']

If that json is in a file, do the following to load it:

import json
jsonFile = open('your_filename.json', 'r')
values = json.load(jsonFile)
jsonFile.close()

If that json is from a URL, do the following to load it:

import urllib, json
f = urllib.urlopen("http://domain/path/jsonPage")
values = json.load(f)
f.close()

To print ALL of the criteria, you could:

for criteria in values['criteria']:
    for key, value in criteria.iteritems():
        print key, 'is:', value
    print ''

I wrote a jQuery plugin for doing this. By default it checks the current URL (because that's already loaded once from the Web) or you can specify a URL to use as an argument. Always doing a request to Google isn't the best idea because it's blocked in different countries at different times. Also you might be at the mercy of what the connection across a particular ocean/weather front/political climate might be like that day.

The above solutions must work. However you can try this one:

OnClientClick="return SomeMethod();return false;"

and remove return statement from the method.

Ports

The ports section will publish ports on the host. Docker will setup a forward for a specific port from the host network into the container. By default this is implemented with a userspace proxy process (docker-proxy) that listens on the first port, and forwards into the container, which needs to listen on the second point. If the container is not listening on the destination port, you will still see something listening on the host, but get a connection refused if you try to connect to that host port, from the failed forward into your container.

Note, the container must be listening on all network interfaces since this proxy is not running within the container's network namespace and cannot reach 127.0.0.1 inside the container. The IPv4 method for that is to configure your application to listen on 0.0.0.0.

Also note that published ports do not work in the opposite direction. You cannot connect to a service on the host from the container by publishing a port. Instead you'll find docker errors trying to listen to the already-in-use host port.

Expose

Expose is documentation. It sets metadata on the image, and when running, on the container too. Typically you configure this in the Dockerfile with the EXPOSE instruction, and it serves as documentation for the users running your image, for them to know on which ports by default your application will be listening. When configured with a compose file, this metadata is only set on the container. You can see the exposed ports when you run a docker inspect on the image or container.

There are a few tools that rely on exposed ports. In docker, the -P flag will publish all exposed ports onto ephemeral ports on the host. There are also various reverse proxies that will default to using an exposed port when sending traffic to your application if you do not explicitly set the container port.

Other than those external tools, expose has no impact at all on the networking between containers. You only need a common docker network, and connecting to the container port, to access one container from another. If that network is user created (e.g. not the default bridge network named bridge), you can use DNS to connect to the other containers.

Try renaming your 'proguard-rules.txt' file to 'proguard-android.txt' and remove the reference to 'proguard-rules.txt' in your gradle file. The getDefaultProguardFile(...) call references a different default proguard file, one provided by Google and not that in your project. So remove this as well, so that here the gradle file reads:

buildTypes {
    release {
        runProguard true
        proguardFile 'proguard-android.txt'
    }
}

Hibernate queries are case sensitive with property names (because they end up relying on getter/setter methods on the @Entity).

Make sure you refer to the property as fileName in the Criteria query, not filename.

Specifically, Hibernate will call the getter method of the filename property when executing that Criteria query, so it will look for a method called getFilename(). But the property is called FileName and the getter getFileName().

So, change the projection like so:

criteria.setProjection(Projections.property("fileName"));

Both these will give you the first child node:

console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);

If you need the first child that is an element node then use:

console.log(parentElement.children[0]);

Edit

Ah, I see your problem now; parentElement is an array.

If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0] to dearray (yes, I made that word up) the element:

var parentElement = document.getElementsByClassName("uniqueClassName")[0];

If you just want to remove untracked files, do this:

git clean -df

add x to that if you want to also include specifically ignored files. I use git clean -dfx a lot throughout the day.

You can create custom git by just writing a script called git-whatever and having it in your path.

You probably want to pass "a" as the mode argument. See the docs for open().

with open("foo", "a") as f:
    f.write("cool beans...")

There are other permutations of the mode argument for updating (+), truncating (w) and binary (b) mode but starting with just "a" is your best bet.

The code itself is working correctly. The problem is, that the program working path is pointing to other place than you think.

Use this line and see where the path is:

System.out.println(new File(".").getAbsoluteFile());

1. Go to the folder platform-tools in cmd folder platform tools available in the Android folder where you have Android backup files.

2. Type the following

   adb kill-server
   

   and

   adb start-server
   

   then type

   adb devices
   
   adb kill-server
   

You can now see your device.

So there is two ways to pass values from fragment/activity to dialog fragment:-

1. Create dialog fragment object with make setter method and pass value/argument.

2. Pass value/argument through bundle.

Method 1:

// Fragment or Activity 
@Override
public void onClick(View v) {
     DialogFragmentWithSetter dialog = new DialogFragmentWithSetter();
     dialog.setValue(header, body);
     dialog.show(getSupportFragmentManager(), "DialogFragmentWithSetter");         
}


//  your dialog fragment
public class MyDialogFragment extends DialogFragment {
    String header; 
    String body;
    public void setValue(String header, String body) {   
          this.header = header;
          this.body = body;
    }
    // use above variable into your dialog fragment
}

Note:- This is not best way to do

Method 2:

// Fragment or Activity 
@Override
public void onClick(View v) {
     DialogFragmentWithSetter dialog = new DialogFragmentWithSetter();
     
     Bundle bundle = new Bundle();
     bundle.putString("header", "Header");
     bundle.putString("body", "Body");  
     dialog.setArguments(bundle);
     dialog.show(getSupportFragmentManager(), "DialogFragmentWithSetter");         
}


//  your dialog fragment
public class MyDialogFragment extends DialogFragment {
    String header; 
    String body;
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if (getArguments() != null) {
             header = getArguments().getString("header","");
             body = getArguments().getString("body","");
        }
    }
    // use above variable into your dialog fragment
}

Note:- This is the best way to do.

You can use std::nextafter with a fixed factor of the epsilon of a value like the following:

bool isNearlyEqual(double a, double b)
{
  int factor = /* a fixed factor of epsilon */;

  double min_a = a - (a - std::nextafter(a, std::numeric_limits<double>::lowest())) * factor;
  double max_a = a + (std::nextafter(a, std::numeric_limits<double>::max()) - a) * factor;

  return min_a <= b && max_a >= b;
}

The use of line system("PAUSE") will fix that problem and also include the pre processor directory #include<stdlib.h>.

Since you ask for other better ways to handle the problem, here's another way using data.table:

require(data.table) ## 1.9.2+
setDT(df)
df[a %in% c(0,1,3,4) | c == 4, g := 3L]
df[a %in% c(2,5,7) | (a==1 & b==4), g := 2L]

Note the order of conditional statements is reversed to get g correctly. There's no copy of g made, even during the second assignment - it's replaced in-place.

On larger data this would have better performance than using nested if-else, as it can evaluate both 'yes' and 'no' cases, and nesting can get harder to read/maintain IMHO.

Here's a benchmark on relatively bigger data:

# R version 3.1.0
require(data.table) ## 1.9.2
require(dplyr)
DT <- setDT(lapply(1:6, function(x) sample(7, 1e7, TRUE)))
setnames(DT, letters[1:6])
# > dim(DT) 
# [1] 10000000        6
DF <- as.data.frame(DT)

DT_fun <- function(DT) {
    DT[(a %in% c(0,1,3,4) | c == 4), g := 3L]
    DT[a %in% c(2,5,7) | (a==1 & b==4), g := 2L]
}

DPLYR_fun <- function(DF) {
    mutate(DF, g = ifelse(a %in% c(2,5,7) | (a==1 & b==4), 2L, 
            ifelse(a %in% c(0,1,3,4) | c==4, 3L, NA_integer_)))
}

BASE_fun <- function(DF) { # R v3.1.0
    transform(DF, g = ifelse(a %in% c(2,5,7) | (a==1 & b==4), 2L, 
            ifelse(a %in% c(0,1,3,4) | c==4, 3L, NA_integer_)))
}

system.time(ans1 <- DT_fun(DT))
#   user  system elapsed 
#  2.659   0.420   3.107 

system.time(ans2 <- DPLYR_fun(DF))
#   user  system elapsed 
# 11.822   1.075  12.976 

system.time(ans3 <- BASE_fun(DF))
#   user  system elapsed 
# 11.676   1.530  13.319 

identical(as.data.frame(ans1), as.data.frame(ans2))
# [1] TRUE

identical(as.data.frame(ans1), as.data.frame(ans3))
# [1] TRUE

Not sure if this is an alternative you'd asked for, but I hope it helps.

Give the path relative to your project.

Create a folder called resources in your src and put your config file there.

   configuration.configure("/resources/hibernate.cfg.xml");

And If you check your code

Configuration  configuration = new Configuration().configure( "C:\\Users\\Nikolay_Tkachev\\workspace\\hiberTest\\src\\logic\\hibernate.cfg.xml");
return new Configuration().configure().buildSessionFactory();

In two lines you are creating two configuration objects.

That should work(haven't tested) if you write,

Configuration  configuration = new Configuration().configure( "C:\\Users\\Nikolay_Tkachev\\workspace\\hiberTest\\src\\logic\\hibernate.cfg.xml");
return  configuration.buildSessionFactory();

But It fails after you deploy on the server,Since you are using system path than project relative path.

You can add atom beauty package for formatting text in atom..

file --> setting --> Install

then you type atom-beautify in search area.

then click Package button.. select atom beuty and install it.

next you can format your text using (Alt + ctrl + b) or right click and select beautify editor contents

for a pure shell solution without calling external program:

NL=$'\n'    # define a variable to reference 'newline'

testVar=${testVar%$NL}    # removes trailing 'NL' from string

Your code works for me

$date = '15-12-2016';
$nameOfDay = date('D', strtotime($date));
echo $nameOfDay;

Use l instead of D, if you prefer the full textual representation of the name

I wrote the following code to convert an image from sdcard to a Base64 encoded string to send as a JSON object.And it works great:

String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
    fis = new FileInputStream(imagefile);
    } catch (FileNotFoundException e) {
    e.printStackTrace();
}

Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);    
byte[] b = baos.toByteArray(); 
encImage = Base64.encodeToString(b, Base64.DEFAULT);

I think the problem is with the spaces. I had my variable at the System variables but it didn't work. When I changed variable Progra~1 = 'Program Files' everything works fine.

M2_HOME C:\Progra~1\Maven\apache-maven-3.1.1

I also moved my M2_HOME at the end of the PATH(%M2_HOME%\bin) I'm not sure if this has any difference.

As demonstrated by many of the complicated, ugly answers presented, Dates and Times can be a nightmare for programmers using any language. My approach is to convert dates and 'delta t' values into Epoch Time (in ms), perform any arithmetic, then convert back to "human time."

// Given a number of days, return a Date object
//   that many days in the future. 
function getFutureDate( days ) {

    // Convert 'days' to milliseconds
    var millies = 1000 * 60 * 60 * 24 * days;

    // Get the current date/time
    var todaysDate = new Date();

    // Get 'todaysDate' as Epoch Time, then add 'days' number of mSecs to it
    var futureMillies = todaysDate.getTime() + millies;

    // Use the Epoch time of the targeted future date to create
    //   a new Date object, and then return it.
    return new Date( futureMillies );
}

// Use case: get a Date that's 60 days from now.
var twoMonthsOut = getFutureDate( 60 );

This was written for a slightly different use case, but you should be able to easily adapt it for related tasks.

EDIT: Full source here!

I think that the thing you must keep in mind is that your XML is being processed by a machine, not a human, so it only needs to be readable for the machine.

In other words, I think you should use whatever XML schema you need to make parsing/processing the rules as efficient as possible at run time.

As far as your current schema goes, I think that the id attribute should be unique per element, so perhaps you should use a different attribute to capture the relationship among your IF, THEN, and ELSE elements.

The below JavaScript code sends "text" to be spoken/converted to mp3 audio to google cloud text-to-speech API and gets mp3 audio content as response back.

 var text-to-speech = function(state) {
    const url = 'https://texttospeech.googleapis.com/v1beta1/text:synthesize?key=GOOGLE_API_KEY'
    const data = {
      'input':{
         'text':'Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets.'
      },
      'voice':{
         'languageCode':'en-gb',
         'name':'en-GB-Standard-A',
         'ssmlGender':'FEMALE'
      },

        },
        body:JSON.stringify(data),
        method:"POST"
     };
    fetch(url,otherparam)
    .then(data=>{return data.json()})

When calling java use the -Xmx Flag for example -Xmx512m for 512 megs for the heap size. You may also want to consider the -xms flag to start the heap larger if you are going to have it grow right from the start. The default size is 128megs.

What worked for me was to make sure the input 'frame' size is equal to output video's size (in this case, (680, 480) ).

http://answers.opencv.org/question/27902/how-to-record-video-using-opencv-and-python/

Here is my working code (Mac OSX Sierra 10.12.6):

cap = cv2.VideoCapture(0)
cap.set(3,640)
cap.set(4,480)

fourcc = cv2.VideoWriter_fourcc(*'MP4V')
out = cv2.VideoWriter('output.mp4', fourcc, 20.0, (640,480))

while(True):
    ret, frame = cap.read()
    out.write(frame)
    cv2.imshow('frame', frame)
    c = cv2.waitKey(1)
    if c & 0xFF == ord('q'):
        break

cap.release()
out.release()
cv2.destroyAllWindows()

Note: I installed openh264 as suggested by @10SecTom but I'm not sure if that was relevant to the problem.

Just in case:

brew install openh264

TimezoneDb provides a free API: http://timezonedb.com/api

GenoNames also has a RESTful API available to get the current time for a given location: http://www.geonames.org/export/ws-overview.html.

You can use Greenwich, UK if you'd like GMT.

You can use commons-collections4 CollectionUtils

Collection<Integer> collection1 = Arrays.asList(1, 2, 4, 5, 7, 8);
Collection<Integer> collection2 = Arrays.asList(2, 3, 4, 6, 8);

Collection<Integer> intersection = CollectionUtils.intersection(collection1, collection2);
System.out.println(intersection); // [2, 4, 8]

Collection<Integer> union = CollectionUtils.union(collection1, collection2);
System.out.println(union); // [1, 2, 3, 4, 5, 6, 7, 8]

Collection<Integer> subtract = CollectionUtils.subtract(collection1, collection2);
System.out.println(subtract); // [1, 5, 7]

There is no do-while loop in Python.

This is a similar construct, taken from the link above.

 while True:
     do_something()
     if condition():
        break

There's a Windows Explorer extension made by the dude who makes tools for SVN that will at least open a command prompt window.

I haven't tried it yet, so I don't know if it'll do PowerShell, but I wanted to share the love with my Stack Overflow brethren:

http://tools.tortoisesvn.net/StExBar

I faced similar issue. My controller name was documents. It manages uploaded documents. It was working fine and started showing this error after completion of code. The mistake I did is - Created a folder 'Documents' to save the uploaded files. So controller name and folder name were same - which made the issue.

In python 3, you can use:

import locale
locale.setlocale( locale.LC_ALL, 'English_United States.1252' )
locale.currency( 1234.50, grouping = True )

Output

'$1,234.50'

Changes to be made in the Android manifest are:

android:configChanges="keyboardHidden|orientation" 

Additions to be made inside activity are:

public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks the orientation of the screen
    if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
        Toast.makeText(this, "landscape", Toast.LENGTH_SHORT).show();
    } else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
        Toast.makeText(this, "portrait", Toast.LENGTH_SHORT).show();
    }
}

If you want to only trigger validation when the input looses focus you can use onBlur

Trivia: React <17 listens to blur event and >=17 listens to focusout event.

your div looks like this:

<div id="someId">Some Value</div>

With jquery:

   <script type="text/javascript">
     $(function(){
         var text = $('#someId').html(); 
         //or
         var text = $('#someId').text();
       };
  </script> 

I do not work with google android but I think you'll find it's not that hard to get this working. If you read the relevant bit of the java tutorial you'll see that a registered cookiehandler gets callbacks from the HTTP code.

So if there is no default (have you checked if CookieHandler.getDefault() really is null?) then you can simply extend CookieHandler, implement put/get and make it work pretty much automatically. Be sure to consider concurrent access and the like if you go that route.

edit: Obviously you'd have to set an instance of your custom implementation as the default handler through CookieHandler.setDefault() to receive the callbacks. Forgot to mention that.

When using a VM, I use these steps to inspect changes to the registry:

1. Using 7-Zip, open the vdi/vhd/vmdk file and extract the folder C:\Windows\System32\config
2. Run OfflineRegistryView to convert the registry to plaintext
   • Set the 'Config Folder' to the folder you extracted
   • Set the 'Base Key' to HKLM\SYSTEM or HKLM\SOFTWARE
   • Set the 'Subkey Depth' to 'Unlimited'
   • Press the 'Go' button

Now use your favourite diff program to compare the 'before' and 'after' snapshots.

The cursor is the Interface that represents a 2-dimensional table of any database.

When you try to retrieve some data using SELECT statement, then the database will 1st create a CURSOR object and return its reference to you.

The pointer of this returned reference is pointing to the 0th location which is otherwise called as before the first location of the Cursor, so when you want to retrieve data from the cursor, you have to 1st move to the 1st record so we have to use moveToFirst

When you invoke moveToFirst() method on the Cursor, it takes the cursor pointer to the 1st location. Now you can access the data present in the 1st record

The best way to look :

Cursor cursor

for (cursor.moveToFirst(); 
     !cursor.isAfterLast();  
     cursor.moveToNext()) {
                  .........
     }

Normalize.css :Every browser is coming with some default css styles that will, for example, add padding around a paragraph or title.If you add the normalize style sheet all those browser default rules will be reset so for this instance 0px padding on tags.Here is a couple of links for more details: https://necolas.github.io/normalize.css/ http://nicolasgallagher.com/about-normalize-css/

Try this:

<tr ng-repeat="player in players | filter:{id: player_id, name:player_name} | filter:ageFilter">

$scope.ageFilter = function (player) {

}

Solution:

Set the property RetainSameConnection on the Connection Manager to True so that temporary table created in one Control Flow task can be retained in another task.

Here is a sample SSIS package written in SSIS 2008 R2 that illustrates using temporary tables.

Walkthrough:

Create a stored procedure that will create a temporary table named ##tmpStateProvince and populate with few records. The sample SSIS package will first call the stored procedure and then will fetch the temporary table data to populate the records into another database table. The sample package will use the database named Sora Use the below create stored procedure script.

USE Sora;
GO

CREATE PROCEDURE dbo.PopulateTempTable
AS
BEGIN
    
    SET NOCOUNT ON;

    IF OBJECT_ID('TempDB..##tmpStateProvince') IS NOT NULL
        DROP TABLE ##tmpStateProvince;

    CREATE TABLE ##tmpStateProvince
    (
            CountryCode     nvarchar(3)         NOT NULL
        ,   StateCode       nvarchar(3)         NOT NULL
        ,   Name            nvarchar(30)        NOT NULL
    );

    INSERT INTO ##tmpStateProvince 
        (CountryCode, StateCode, Name)
    VALUES
        ('CA', 'AB', 'Alberta'),
        ('US', 'CA', 'California'),
        ('DE', 'HH', 'Hamburg'),
        ('FR', '86', 'Vienne'),
        ('AU', 'SA', 'South Australia'),
        ('VI', 'VI', 'Virgin Islands');
END
GO

Create a table named dbo.StateProvince that will be used as the destination table to populate the records from temporary table. Use the below create table script to create the destination table.

USE Sora;
GO

CREATE TABLE dbo.StateProvince
(
        StateProvinceID int IDENTITY(1,1)   NOT NULL
    ,   CountryCode     nvarchar(3)         NOT NULL
    ,   StateCode       nvarchar(3)         NOT NULL
    ,   Name            nvarchar(30)        NOT NULL
    CONSTRAINT [PK_StateProvinceID] PRIMARY KEY CLUSTERED
        ([StateProvinceID] ASC)
) ON [PRIMARY];
GO

Create an SSIS package using Business Intelligence Development Studio (BIDS). Right-click on the Connection Managers tab at the bottom of the package and click New OLE DB Connection... to create a new connection to access SQL Server 2008 R2 database.

Click New... on Configure OLE DB Connection Manager.

Perform the following actions on the Connection Manager dialog.

• Select Native OLE DB\SQL Server Native Client 10.0 from Provider since the package will connect to SQL Server 2008 R2 database
• Enter the Server name, like MACHINENAME\INSTANCE
• Select Use Windows Authentication from Log on to the server section or whichever you prefer.
• Select the database from Select or enter a database name, the sample uses the database name Sora.
• Click Test Connection
• Click OK on the Test connection succeeded message.
• Click OK on Connection Manager

The newly created data connection will appear on Configure OLE DB Connection Manager. Click OK.

OLE DB connection manager KIWI\SQLSERVER2008R2.Sora will appear under the Connection Manager tab at the bottom of the package. Right-click the connection manager and click Properties

Set the property RetainSameConnection on the connection KIWI\SQLSERVER2008R2.Sora to the value True.

Right-click anywhere inside the package and then click Variables to view the variables pane. Create the following variables.

• A new variable named PopulateTempTable of data type String in the package scope SO_5631010 and set the variable with the value EXEC dbo.PopulateTempTable.

• A new variable named FetchTempData of data type String in the package scope SO_5631010 and set the variable with the value SELECT CountryCode, StateCode, Name FROM ##tmpStateProvince

Drag and drop an Execute SQL Task on to the Control Flow tab. Double-click the Execute SQL Task to view the Execute SQL Task Editor.

On the General page of the Execute SQL Task Editor, perform the following actions.

• Set the Name to Create and populate temp table
• Set the Connection Type to OLE DB
• Set the Connection to KIWI\SQLSERVER2008R2.Sora
• Select Variable from SQLSourceType
• Select User::PopulateTempTable from SourceVariable
• Click OK

Drag and drop a Data Flow Task onto the Control Flow tab. Rename the Data Flow Task as Transfer temp data to database table. Connect the green arrow from the Execute SQL Task to the Data Flow Task.

Double-click the Data Flow Task to switch to Data Flow tab. Drag and drop an OLE DB Source onto the Data Flow tab. Double-click OLE DB Source to view the OLE DB Source Editor.

On the Connection Manager page of the OLE DB Source Editor, perform the following actions.

• Select KIWI\SQLSERVER2008R2.Sora from OLE DB Connection Manager
• Select SQL command from variable from Data access mode
• Select User::FetchTempData from Variable name
• Click Columns page

Clicking Columns page on OLE DB Source Editor will display the following error because the table ##tmpStateProvince specified in the source command variable does not exist and SSIS is unable to read the column definition.

To fix the error, execute the statement EXEC dbo.PopulateTempTable using SQL Server Management Studio (SSMS) on the database Sora so that the stored procedure will create the temporary table. After executing the stored procedure, click Columns page on OLE DB Source Editor, you will see the column information. Click OK.

Drag and drop OLE DB Destination onto the Data Flow tab. Connect the green arrow from OLE DB Source to OLE DB Destination. Double-click OLE DB Destination to open OLE DB Destination Editor.

On the Connection Manager page of the OLE DB Destination Editor, perform the following actions.

• Select KIWI\SQLSERVER2008R2.Sora from OLE DB Connection Manager
• Select Table or view - fast load from Data access mode
• Select [dbo].[StateProvince] from Name of the table or the view
• Click Mappings page

Click Mappings page on the OLE DB Destination Editor would automatically map the columns if the input and output column names are same. Click OK. Column StateProvinceID does not have a matching input column and it is defined as an IDENTITY column in database. Hence, no mapping is required.

Data Flow tab should look something like this after configuring all the components.

Click the OLE DB Source on Data Flow tab and press F4 to view Properties. Set the property ValidateExternalMetadata to False so that SSIS would not try to check for the existence of the temporary table during validation phase of the package execution.

Execute the query select * from dbo.StateProvince in the SQL Server Management Studio (SSMS) to find the number of rows in the table. It should be empty before executing the package.

Execute the package. Control Flow shows successful execution.

In Data Flow tab, you will notice that the package successfully processed 6 rows. The stored procedure created early in this posted inserted 6 rows into the temporary table.

Execute the query select * from dbo.StateProvince in the SQL Server Management Studio (SSMS) to find the 6 rows successfully inserted into the table. The data should match with rows founds in the stored procedure.

The above example illustrated how to create and use temporary table within a package.

This should work

<option *ngFor="let title of titleArray" 
    [value]="title.Value" 
    [attr.selected]="passenger.Title==title.Text ? true : null">
  {{title.Text}}
</option>

I'm not sure the attr. part is necessary.

It is recommended to use autoreconf -fi instead of manually calling aclocal;autoconf;automake; #and whatever else to properly populate aclocal.m4 and so on.

Adding ACLOCAL_AMFLAGS = -I m4 (to the toplevel Makefile.am) and AC_CONFIG_MACRO_DIR([m4]) is currently still optional if you do not use any own m4 files, but of course, doing it will silence the proocess :)

I want to add one Hello, World! example that explains the basics of slices for the very beginners. It helped me a lot.

Let's have a list with six values ['P', 'Y', 'T', 'H', 'O', 'N']:

+---+---+---+---+---+---+
| P | Y | T | H | O | N |
+---+---+---+---+---+---+
  0   1   2   3   4   5

Now the simplest slices of that list are its sublists. The notation is [<index>:<index>] and the key is to read it like this:

[ start cutting before this index : end cutting before this index ]

Now if you make a slice [2:5] of the list above, this will happen:

        |           |
+---+---|---+---+---|---+
| P | Y | T | H | O | N |
+---+---|---+---+---|---+
  0   1 | 2   3   4 | 5

You made a cut before the element with index 2 and another cut before the element with index 5. So the result will be a slice between those two cuts, a list ['T', 'H', 'O'].

This is is the same as a weighted average problem where all the weights are the same, and there are two dimensions.

Find the average of all latitudes for your center latitude and the average of all longitudes for the center longitude.

Caveat Emptor: This is a close distance approximation and the error will become unruly when the deviations from the mean are more than a few miles due to the curvature of the Earth. Remember that latitudes and longitudes are degrees (not really a grid).

another solution for variety sake..

public extension String {
    public var validPhoneNumber:Bool {
        let types:NSTextCheckingType = [.PhoneNumber]
        guard let detector = try? NSDataDetector(types: types.rawValue) else { return false }

        if let match = detector.matchesInString(self, options: [], range: NSMakeRange(0, characters.count)).first?.phoneNumber {
            return match == self
        }else{
            return false
        }
    }
}

//and use like so:
if "16465551212".validPhoneNumber {
    print("valid phone number")
}

This if an Info message that could pop in your LogCat on many situations.

In my case, it happened when I was inflating several views from XML layout files programmatically. The message is harmless by itself, but could be the sign of a later problem that would use all the RAM your App is allowed to use and cause the mega-evil Force Close to happen. I have grown to be the kind of Developer that likes to see his Log WARN/INFO/ERROR Free. ;)

So, this is my own experience:

I got the message:

10-09 01:25:08.373: I/Choreographer(11134): Skipped XXX frames!  The application may be doing too much work on its main thread.

... when I was creating my own custom "super-complex multi-section list" by inflating a view from XML and populating its fields (images, text, etc...) with the data coming from the response of a REST/JSON web service (without paging capabilities) this views would act as rows, sub-section headers and section headers by adding all of them in the correct order to a LinearLayout (with vertical orientation inside a ScrollView). All of that to simulate a listView with clickable elements... but well, that's for another question.

As a responsible Developer you want to make the App really efficient with the system resources, so the best practice for lists (when your lists are not so complex) is to use a ListActivity or ListFragment with a Loader and fill the ListView with an Adapter, this is supposedly more efficient, in fact it is and you should do it all the time, again... if your list is not so complex.

Solution: I implemented paging on my REST/JSON web service to prevent "big response sizes" and I wrapped the code that added the "rows", "section headers" and "sub-section headers" views on an AsyncTask to keep the Main Thread cool.

So... I hope my experience helps someone else that is cracking their heads open with this Info message.

Happy hacking!

If you want to catch the Back Button have a look at this post on the Android Developer Blog. It covers the easier way to do this in Android 2.0 and the best way to do this for an application that runs on 1.x and 2.0.

However, if your Activity is Stopped it still may be killed depending on memory availability on the device. If you want a process to run with no UI you should create a Service. The documentation says the following about Services:

A service doesn't have a visual user interface, but rather runs in the background for an indefinite period of time. For example, a service might play background music as the user attends to other matters, or it might fetch data over the network or calculate something and provide the result to activities that need it.

These seems appropriate for your requirements.

1. First, find your build.gradle in your all modules in project, include app/build.gradle. Find the compileSdkVersion inside android tag, in this case, compile sdk version is 30:

2. Next, open SDK Manager > SDK Platforms, check correct version then install selected platforms. After installed, go to menu File > Sync project with Gradle files....

This issue often appear when project has many modules, each module use different compile SDK version, so app may be able to build but IDE have some issue while processing your resources.

System Preferences -> System Security Privacy -> Allow oracle.xxxx; then reinstalling the virtualBox.

Instance variable on a class:

class Parent
  @things = []
  def self.things
    @things
  end
  def things
    self.class.things
  end
end

class Child < Parent
  @things = []
end

Parent.things << :car
Child.things  << :doll
mom = Parent.new
dad = Parent.new

p Parent.things #=> [:car]
p Child.things  #=> [:doll]
p mom.things    #=> [:car]
p dad.things    #=> [:car]

Class variable:

class Parent
  @@things = []
  def self.things
    @@things
  end
  def things
    @@things
  end
end

class Child < Parent
end

Parent.things << :car
Child.things  << :doll

p Parent.things #=> [:car,:doll]
p Child.things  #=> [:car,:doll]

mom = Parent.new
dad = Parent.new
son1 = Child.new
son2 = Child.new
daughter = Child.new

[ mom, dad, son1, son2, daughter ].each{ |person| p person.things }
#=> [:car, :doll]
#=> [:car, :doll]
#=> [:car, :doll]
#=> [:car, :doll]
#=> [:car, :doll]

With an instance variable on a class (not on an instance of that class) you can store something common to that class without having sub-classes automatically also get them (and vice-versa). With class variables, you have the convenience of not having to write self.class from an instance object, and (when desirable) you also get automatic sharing throughout the class hierarchy.

Merging these together into a single example that also covers instance variables on instances:

class Parent
  @@family_things = []    # Shared between class and subclasses
  @shared_things  = []    # Specific to this class

  def self.family_things
    @@family_things
  end
  def self.shared_things
    @shared_things
  end

  attr_accessor :my_things
  def initialize
    @my_things = []       # Just for me
  end
  def family_things
    self.class.family_things
  end
  def shared_things
    self.class.shared_things
  end
end

class Child < Parent
  @shared_things = []
end

And then in action:

mama = Parent.new
papa = Parent.new
joey = Child.new
suzy = Child.new

Parent.family_things << :house
papa.family_things   << :vacuum
mama.shared_things   << :car
papa.shared_things   << :blender
papa.my_things       << :quadcopter
joey.my_things       << :bike
suzy.my_things       << :doll
joey.shared_things   << :puzzle
suzy.shared_things   << :blocks

p Parent.family_things #=> [:house, :vacuum]
p Child.family_things  #=> [:house, :vacuum]
p papa.family_things   #=> [:house, :vacuum]
p mama.family_things   #=> [:house, :vacuum]
p joey.family_things   #=> [:house, :vacuum]
p suzy.family_things   #=> [:house, :vacuum]

p Parent.shared_things #=> [:car, :blender]
p papa.shared_things   #=> [:car, :blender]
p mama.shared_things   #=> [:car, :blender]
p Child.shared_things  #=> [:puzzle, :blocks]  
p joey.shared_things   #=> [:puzzle, :blocks]
p suzy.shared_things   #=> [:puzzle, :blocks]

p papa.my_things       #=> [:quadcopter]
p mama.my_things       #=> []
p joey.my_things       #=> [:bike]
p suzy.my_things       #=> [:doll] 

With ssh key based authentication enabled, the following script would work.

for x in `ssh user@remotehost 'find /usr/some -type f -name *.class'`; do y=$(echo $x|sed 's/.[^/]*$//'|sed "s/^\/usr//"); mkdir -p /usr/project/backup$y; scp $(echo 'user@remotehost:'$x) /usr/project/backup$y/; done

Make sure Blog has methods equals(Object) and hashCode() defined, and addAll(list) then to a new HashSet(), or new LinkedHashSet() if the order is important.

Better yet, use a Set instead of a List from the start, since you obviously don't want duplicates, it's better that your data model reflects that rather than having to remove them after the fact.

Cocos2d-x within uikit tutorial http://jpsarda.tumblr.com/post/24983791554/mixing-cocos2d-x-uikit

You can use int casting which allows the base specification.

int(b, 2)  # Convert a binary string to a decimal int.

Probably because you can't have part of an iterable. Also, floats are imprecise.

i had this question and found another answer here: copy region of interest

If we consider (0,0) as top left corner of image called im with left-to-right as x direction and top-to-bottom as y direction. and we have (x1,y1) as the top-left vertex and (x2,y2) as the bottom-right vertex of a rectangle region within that image, then:

roi = im[y1:y2, x1:x2]

here is a comprehensive resource on numpy array indexing and slicing which can tell you more about things like cropping a part of an image. images would be stored as a numpy array in opencv2.

:)

For some reason, the accepted answer worked for me only if being used once on the page, but in my case I was trying to save data on many elements on the page and the data was somehow lost on all except the first element.

As an alternative, I ended up writing the data out to the dom and parsing it back in when needed. Perhaps it's less efficient, but worked well for my purpose because I'm really prototyping data and not writing this for production.

To save the data I used:

$('#myElement').attr('data-key', JSON.stringify(jsonObject));

To then read the data back is the same as the accepted answer, namely:

var getBackMyJSON = $('#myElement').data('key');

Doing it this way also made the data appear in the dom if I were to inspect the element with Chrome's debugger.

You need to declare disconnectFunc as a function pointer, not a void pointer. You also need to call it as a function (with parentheses), and no "*" is needed.

Here is a util class for marshaling and unmarshaling objects. In my case it was a nested class, so I made it static JAXBUtils.

import javax.xml.bind.JAXB;
import java.io.StringReader;
import java.io.StringWriter;

public class JAXBUtils
{
    /**
     * Unmarshal an XML string
     * @param xml     The XML string
     * @param type    The JAXB class type.
     * @return The unmarshalled object.
     */
    public <T> T unmarshal(String xml, Class<T> type)
    {
        StringReader reader = new StringReader(xml);
        return javax.xml.bind.JAXB.unmarshal(reader, type);
    }

    /**
     * Marshal an Object to XML.
     * @param object    The object to marshal.
     * @return The XML string representation of the object.
     */
    public String marshal(Object object)
    {
        StringWriter stringWriter = new StringWriter();
        JAXB.marshal(object, stringWriter);
        return stringWriter.toString();
    }
}

You can use NSValue for this. An NSValue object is a simple container for a single C or Objective-C data item. It can hold any of the scalar types such as int, float, and char, as well as pointers, structures, and object ids.

Example:

  CGPoint cgPoint = CGPointMake(10,30);
    NSLog(@"%@",[NSValue valueWithCGPoint:cgPoint]);

OUTPUT : NSPoint: {10, 30}

Hope it helps you.

As Matt J wrote, there is itoa, but it's not standard. Your code will be more portable if you use snprintf.

Need to frequently read a large file from last position reading ?

I have created a script used to cut an Apache access.log file several times a day. So I needed to set a position cursor on last line parsed during last execution. To this end, I used file.seek() and file.seek() methods which allows the storage of the cursor in file.

My code :

ENCODING = "utf8"
CURRENT_FILE_DIR = os.path.dirname(os.path.abspath(__file__))

# This file is used to store the last cursor position
cursor_position = os.path.join(CURRENT_FILE_DIR, "access_cursor_position.log")

# Log file with new lines
log_file_to_cut = os.path.join(CURRENT_FILE_DIR, "access.log")
cut_file = os.path.join(CURRENT_FILE_DIR, "cut_access", "cut.log")

# Set in from_line 
from_position = 0
try:
    with open(cursor_position, "r", encoding=ENCODING) as f:
        from_position = int(f.read())
except Exception as e:
    pass

# We read log_file_to_cut to put new lines in cut_file
with open(log_file_to_cut, "r", encoding=ENCODING) as f:
    with open(cut_file, "w", encoding=ENCODING) as fw:
        # We set cursor to the last position used (during last run of script)
        f.seek(from_position)
        for line in f:
            fw.write("%s" % (line))

    # We save the last position of cursor for next usage
    with open(cursor_position, "w", encoding=ENCODING) as fw:
        fw.write(str(f.tell()))

In Get:

public IActionResult Create()
{
    ViewData["Tags"] = new SelectList(_context.Tags, "Id", "Name");
    return View();
}

In Post:

var selectedIds= Request.Form["Tags"];

In View :

<label>Tags</label>
<select  asp-for="Tags"  id="Tags" name="Tags" class="form-control" asp-items="ViewBag.Tags" multiple></select>

For me changing the Emulated Performance setting to "Store a snapshot for faster startup" and unchecking "Use Host GPU" fixed the problem.

The following illustrates the solution, assign your string to a variable pointer to a constant array of char (a string is a constant pointer to a constant array of char - plus length info):

#include <iostream>

void Swap(const char * & left, const char * & right) {
    const char *const temp = left;
    left = right;
    right = temp;
}

int main() {
    const char * x = "Hello"; // These works because you are making a variable
    const char * y = "World"; // pointer to a constant string
    std::cout << "x = " << x << ", y = " << y << '\n';
    Swap(x, y);
    std::cout << "x = " << x << ", y = " << y << '\n';
}

Note that in general, IDE's like Visual Studio will markup a comment in the context of the current language, by selecting the text you wish to turn into a comment, and then using the Ctrl+K Ctrl+C shortcut, or if you are using Resharper / Intelli-J style shortcuts, then Ctrl+/.

Server side Comments:

Razor .cshtml

Like so:

@* Comment goes here *@

.aspx
For those looking for the older .aspx view (and Asp.Net WebForms) server side comment syntax:

<%-- Comment goes here --%>

Client Side Comments

HTML Comment

<!-- Comment goes here -->

Javascript Comment

// One line Comment goes Here
/* Multiline comment
   goes here */

As OP mentions, although not displayed on the browser, client side comments will still be generated for the page / script file on the server and downloaded by the page over HTTP, which unless removed (e.g. minification), will waste I/O, and, since the comment can be viewed by the user by viewing the page source or intercepting the traffic with the browser's Dev Tools or a tool like Fiddler or Wireshark, can also pose a security risk, hence the preference to use server side comments on server generated code (like MVC views or .aspx pages).

The line $('#myTextBox').focus() alone won't put the cursor in the text box, instead use:

$('#myTextBox:text:visible:first').focus();

Works for all browsers and all versions:

JS

jQuery(document).ready(function () {    
    var widthOfSelect = $("#first").width();
    widthOfSelect = widthOfSelect - 13;
    //alert(widthOfSelect);
    jQuery('#first').wrap("<div id='sss' style='width: "+widthOfSelect+"px; overflow: hidden; border-right: #000 1px solid;' width=20></div>");
});

HTML

<select class="first" id="first">
  <option>option1</option>
  <option>option2</option>
  <option>option3</option>
</select>

I believe that

nzd$date <- as.Date(nzd$date, format = "%d/%m/%Y")

is sufficient.

Since Python is a strongly typed language, concatenating a string and an integer as you may do in Perl makes no sense, because there's no defined way to "add" strings and numbers to each other.

Explicit is better than implicit.

...says "The Zen of Python", so you have to concatenate two string objects. You can do this by creating a string from the integer using the built-in str() function:

>>> "abc" + str(9)
'abc9'

Alternatively use Python's string formatting operations:

>>> 'abc%d' % 9
'abc9'

Perhaps better still, use str.format():

>>> 'abc{0}'.format(9)
'abc9'

The Zen also says:

There should be one-- and preferably only one --obvious way to do it.

Which is why I've given three options. It goes on to say...

Although that way may not be obvious at first unless you're Dutch.

Try swapping your colon : for a bar |. that should do it

<a href="file://C|/path/to/file/file.html">Link Anchor</a>

using (FileStream fs = File.OpenRead(binarySourceFile.Path))
    using (BinaryReader reader = new BinaryReader(fs))
    {              
        // Read in all pairs.
        while (reader.BaseStream.Position != reader.BaseStream.Length)
        {
            Item item = new Item();
            item.UniqueId = reader.ReadString();
            item.StringUnique = reader.ReadString();
            result.Add(item);
        }
    }
    return result;  

SerialPort (RS-232 Serial COM Port) in C# .NET
This article explains how to use the SerialPort class in .NET to read and write data, determine what serial ports are available on your machine, and how to send files. It even covers the pin assignments on the port itself.

Example Code:

using System;
using System.IO.Ports;
using System.Windows.Forms;

namespace SerialPortExample
{
  class SerialPortProgram
  {
    // Create the serial port with basic settings
    private SerialPort port = new SerialPort("COM1",
      9600, Parity.None, 8, StopBits.One);

    [STAThread]
    static void Main(string[] args)
    { 
      // Instatiate this class
      new SerialPortProgram();
    }

    private SerialPortProgram()
    {
      Console.WriteLine("Incoming Data:");

      // Attach a method to be called when there
      // is data waiting in the port's buffer
      port.DataReceived += new 
        SerialDataReceivedEventHandler(port_DataReceived);

      // Begin communications
      port.Open();

      // Enter an application loop to keep this thread alive
      Application.Run();
    }

    private void port_DataReceived(object sender,
      SerialDataReceivedEventArgs e)
    {
      // Show all the incoming data in the port's buffer
      Console.WriteLine(port.ReadExisting());
    }
  }
}

what about the retrying library on pypi? I have been using it for a while and it does exactly what I want and more (retry on error, retry when None, retry with timeout). Below is example from their website:

import random
from retrying import retry

@retry
def do_something_unreliable():
    if random.randint(0, 10) > 1:
        raise IOError("Broken sauce, everything is hosed!!!111one")
    else:
        return "Awesome sauce!"

print do_something_unreliable()

You could try defining a new DecimalFormat and using it as a Double result to a new double variable.

Example given to make you understand what I just said.

double decimalnumber = 100.2397;
DecimalFormat dnf = new DecimalFormat( "#,###,###,##0.00" );
double roundednumber = new Double(dnf.format(decimalnumber)).doubleValue();

Here is a snippet that does not need ajQuery and will enable alerts in a disabled iframe (like on codepen)

for (var i = 0; i < document.getElementsByTagName('iframe').length; i++) {
    document.getElementsByTagName('iframe')[i].setAttribute('sandbox','allow-modals');
}

Here is a codepen demo working with an alert() after this fix as well: http://codepen.io/nicholasabrams/pen/vNpoBr?editors=001

Some of the other answers mention that Python 3 eliminated 2.x's range and renamed 2.x's xrange to range. However, unless you're using 3.0 or 3.1 (which nobody should be), it's actually a somewhat different type.

As the 3.1 docs say:

Range objects have very little behavior: they only support indexing, iteration, and the len function.

However, in 3.2+, range is a full sequence—it supports extended slices, and all of the methods of collections.abc.Sequence with the same semantics as a list.^*

And, at least in CPython and PyPy (the only two 3.2+ implementations that currently exist), it also has constant-time implementations of the index and count methods and the in operator (as long as you only pass it integers). This means writing 123456 in r is reasonable in 3.2+, while in 2.7 or 3.1 it would be a horrible idea.

_{* The fact that issubclass(xrange, collections.Sequence) returns True in 2.6-2.7 and 3.0-3.1 is a bug that was fixed in 3.2 and not backported.}

I have created a service to use with Angular 5 or higher, it uses the angular.copy() the base of angularjs, it works well for me. Additionally, there are other functions like isUndefined, etc. I hope it helps. Like any optimization, it would be nice to know. regards

One more thing to watch out for is if the second value was another Integer object instead of a literal '0', the '==' operator compares the object pointers and will not auto-unbox.

ie:

Integer a = new Integer(0);   
Integer b = new Integer(0);   
int c = 0;

boolean isSame_EqOperator = (a==b); //false!
boolean isSame_EqMethod = (a.equals(b)); //true
boolean isSame_EqAutoUnbox = ((a==c) && (a.equals(c)); //also true, because of auto-unbox

//Note: for initializing a and b, the Integer constructor 
// is called explicitly to avoid integer object caching 
// for the purpose of the example.

It depends on the specific use case.

If your table is static and only has a short list of values (and there is just a small chance that this would change during a lifetime of DB), I would recommend this construction:

CREATE TABLE Foo 
(
    FooCode VARCHAR(16), -- short code or shortcut, but with some meaning.
    Name NVARCHAR(128), -- full name of entity, can be used as fallback in case when your localization for some language doesn't exist
    LocalizationCode AS ('Foo.' + FooCode) -- This could be a code for your localization table... 
)

Of course, when your table is not static at all, using INT as primary key is the best solution.

I presume that this question is a continuation of this one.

What are you trying to do? Do you really want to dynamically change the text in your TextView objects when the user clicks a button? You can certainly do that, if you have a reason, but, if the text is static, it is usually set in the main.xml file, like this:

<TextView  
android:id="@+id/rate"
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="@string/rate"
/>

The string "@string/rate" refers to an entry in your strings.xml file that looks like this:

<string name="rate">Rate</string>

If you really want to change this text later, you can do so by using Nikolay's example - you'd get a reference to the TextView by utilizing the id defined for it within main.xml, like this:

final TextView textViewToChange = (TextView) findViewById(R.id.rate);
textViewToChange.setText(
    "The new text that I'd like to display now that the user has pushed a button.");

You need to publish the exposed ports by using the following options:

-P (upper case) or --publish-all that will tell Docker to use random ports from your host and map them to the exposed container's ports.

-p (lower case) or --publish=[] that will tell Docker to use ports you manually set and map them to the exposed container's ports.

The second option is preferred because you already know which ports are mapped. If you use the first option then you will need to call docker inspect demo and check which random ports are being used from your host at the Ports section.

Just run the following command:

docker run -it -p 8080:8080 demo

After that your url will work.

One way to do it :

FileStream stream = File.Open(@"c:\working\test.xls", FileMode.Open, FileAccess.Read);

IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);

excelReader.IsFirstRowAsColumnNames = true;

DataSet result = excelReader.AsDataSet();

The result.Tables contains the sheets and the result.tables[0].Rows contains the cell rows.

A late answer, but here is an alternative to the SCOPE_IDENTITY() answers that we ended up using: OUTPUT INSERTED

Return only ID of inserted object:

It allows you to get all or some attributes of the inserted row:

string insertUserSql = @"INSERT INTO dbo.[User](Username, Phone, Email)
                        OUTPUT INSERTED.[Id]
                        VALUES(@Username, @Phone, @Email);";

int newUserId = conn.QuerySingle<int>(
                                insertUserSql,
                                new
                                {
                                    Username = "lorem ipsum",
                                    Phone = "555-123",
                                    Email = "lorem ipsum"
                                },
                                tran);

Return inserted object with ID:

If you wanted you could get Phone and Email or even the whole inserted row:

string insertUserSql = @"INSERT INTO dbo.[User](Username, Phone, Email)
                        OUTPUT INSERTED.*
                        VALUES(@Username, @Phone, @Email);";

User newUser = conn.QuerySingle<User>(
                                insertUserSql,
                                new
                                {
                                    Username = "lorem ipsum",
                                    Phone = "555-123",
                                    Email = "lorem ipsum"
                                },
                                tran);

Also, with this you can return data of deleted or updated rows. Just be careful if you are using triggers because (from link mentioned before):

Columns returned from OUTPUT reflect the data as it is after the INSERT, UPDATE, or DELETE statement has completed but before triggers are executed.

For INSTEAD OF triggers, the returned results are generated as if the INSERT, UPDATE, or DELETE had actually occurred, even if no modifications take place as the result of the trigger operation. If a statement that includes an OUTPUT clause is used inside the body of a trigger, table aliases must be used to reference the trigger inserted and deleted tables to avoid duplicating column references with the INSERTED and DELETED tables associated with OUTPUT.

I originally wrote this answer when TypeScript was still hot-off-the-presses. Five years later, this is an OK overview, but look at Lodewijk's answer below for more depth

1000ft view...

TypeScript is a superset of JavaScript which primarily provides optional static typing, classes and interfaces. One of the big benefits is to enable IDEs to provide a richer environment for spotting common errors as you type the code.

To get an idea of what I mean, watch Microsoft's introductory video on the language.

For a large JavaScript project, adopting TypeScript might result in more robust software, while still being deployable where a regular JavaScript application would run.

It is open source, but you only get the clever Intellisense as you type if you use a supported IDE. Initially, this was only Microsoft's Visual Studio (also noted in blog post from Miguel de Icaza). These days, other IDEs offer TypeScript support too.

Are there other technologies like it?

There's CoffeeScript, but that really serves a different purpose. IMHO, CoffeeScript provides readability for humans, but TypeScript also provides deep readability for tools through its optional static typing (see this recent blog post for a little more critique). There's also Dart but that's a full on replacement for JavaScript (though it can produce JavaScript code)

Example

As an example, here's some TypeScript (you can play with this in the TypeScript Playground)

class Greeter {
    greeting: string;
    constructor (message: string) {
        this.greeting = message;
    }
    greet() {
        return "Hello, " + this.greeting;
    }
}  

And here's the JavaScript it would produce

var Greeter = (function () {
    function Greeter(message) {
        this.greeting = message;
    }
    Greeter.prototype.greet = function () {
        return "Hello, " + this.greeting;
    };
    return Greeter;
})();

Notice how the TypeScript defines the type of member variables and class method parameters. This is removed when translating to JavaScript, but used by the IDE and compiler to spot errors, like passing a numeric type to the constructor.

It's also capable of inferring types which aren't explicitly declared, for example, it would determine the greet() method returns a string.

Debugging TypeScript

Many browsers and IDEs offer direct debugging support through sourcemaps. See this Stack Overflow question for more details: Debugging TypeScript code with Visual Studio

I originally wrote this answer when TypeScript was still hot-off-the-presses. Check out Lodewijk's answer to this question for some more current detail.

I did it like this.

$(document).ready(function(){
    $("#yourid").click(function(){
        $(this).load('@Url.Action("Details")');
    });
});

Details Method:

public IActionResult Details()
        {

            return PartialView("Your Partial View");
        }

public class SubSubClass extends SubClass {

    @Override
    public void print() {
        super.superPrint();
    }

    public static void main(String[] args) {
        new SubSubClass().print();
    }
}

class SuperClass {

    public void print() {
        System.out.println("Printed in the GrandDad");
    }
}

class SubClass extends SuperClass {

    public void superPrint() {
        super.print();
    }
}

Output: Printed in the GrandDad

Right click on "Command prompt" or "PowerShell", in menu click "Run as Administrator" (on Windows XP you can just run it as usual).

As Rick Vanover mentions in See what process is using a TCP port in Windows Server 2008

The following command will show what network traffic is in use at the port level:

Netstat -a -n -o

or

Netstat -a -n -o >%USERPROFILE%\ports.txt

(to open the port and process list in a text editor, where you can search for information you want)

Then,

with the PIDs listed in the netstat output, you can follow up with the Windows Task Manager (taskmgr.exe) or run a script with a specific PID that is using a port from the previous step. You can then use the "tasklist" command with the specific PID that corresponds to a port in question.

Example:

tasklist /svc /FI "PID eq 1348"

As has been noted, parsing the date and time is only useful if you know the format being used by the current user (for example, MM/dd/yy or dd-MM-yyyy just to name two). This could be determined, but by the time you do all the stressing and parsing, you will still end up with some situation where there is an unexpected format used, and more tweaks will be be necessary.

You can also use some external program that will return a date slug in your preferred format, but that has disadvantages of needing to distribute the utility program with your script/batch.

There are also batch tricks using the CMOS clock in a pretty raw way, but that is tooo close to bare wires for most people, and also not always the preferred place to retrieve the date/time.

Below is a solution that avoids the above problems. Yes, it introduces some other issues, but for my purposes I found this to be the easiest, clearest, most portable solution for creating a datestamp in .bat files for modern Windows systems. This is just an example, but I think you will see how to modify for other date and/or time formats, etc.

reg copy "HKCU\Control Panel\International" "HKCU\Control Panel\International-Temp" /f
reg add "HKCU\Control Panel\International" /v sShortDate /d "yyMMdd" /f
@REM reg query "HKCU\Control Panel\International" /v sShortDate
set LogDate=%date%
reg copy "HKCU\Control Panel\International-Temp" "HKCU\Control Panel\International" /f

Assuming that you're only using the array for lookup, you can use a Set (introduced in ES6), which allows you to find an element in O(1), meaning that lookup is sublinear. With the traditional methods of .includes() and .indexOf(), you still may need to look at all 500 (ie: N) elements in your array if the item specified doesn't exist in the array (or is the last item). This can be inefficient, however, with the help of a Set, you don't need to look at all elements, and instead, instantly check if the element is within your set:

const blockedTile = new Set(["118", "67", "190", "43", "135", "520"]);

if(blockedTile.has("118")) {
  // 118 is in your Set
  console.log("Found 118");
}

If for some reason you need to convert your set back into an array, you can do so through the use of Array.from() or the spread syntax (...), however, this will iterate through the entire set's contents (which will be O(N)). Sets also don't keep duplicates, meaning that your array won't contain duplicate items.

Use this one :

 onSelect: function(dateText) {
                 $("input#DateTo").datepicker('option', 'minDate', dateText);
            }

This may be useful : http://jsfiddle.net/injulkarnilesh/xNeTe/

As of this date, the correct way according to the dynamic routing docs is:

this.$route.params.yourProperty

instead of

this.$route.query.yourProperty

No, this will cause the exception to have a different stack trace. Only using a throw without any exception object in the catch handler will leave the stack trace unchanged.

You may want to return a boolean from HandleException whether the exception shall be rethrown or not.

A lot of the answers on here use regexes, this is fine but it doesn't handle new additions to the language too well (like arrow functions and classes). Also of note is that if you use any of these functions on minified code it's going to go . It will use whatever the minified name is. Angular gets around this by allowing you to pass in an ordered array of strings that matches the order of the arguments when registering them with the DI container. So on with the solution:

var esprima = require('esprima');
var _ = require('lodash');

const parseFunctionArguments = (func) => {
    // allows us to access properties that may or may not exist without throwing 
    // TypeError: Cannot set property 'x' of undefined
    const maybe = (x) => (x || {});

    // handle conversion to string and then to JSON AST
    const functionAsString = func.toString();
    const tree = esprima.parse(functionAsString);
    console.log(JSON.stringify(tree, null, 4))
    // We need to figure out where the main params are. Stupid arrow functions 
    const isArrowExpression = (maybe(_.first(tree.body)).type == 'ExpressionStatement');
    const params = isArrowExpression ? maybe(maybe(_.first(tree.body)).expression).params 
                                     : maybe(_.first(tree.body)).params;

    // extract out the param names from the JSON AST
    return _.map(params, 'name');
};

This handles the original parse issue and a few more function types (e.g. arrow functions). Here's an idea of what it can and can't handle as is:

// I usually use mocha as the test runner and chai as the assertion library
describe('Extracts argument names from function signature. ', () => {
    const test = (func) => {
        const expectation = ['it', 'parses', 'me'];
        const result = parseFunctionArguments(toBeParsed);
        result.should.equal(expectation);
    } 

    it('Parses a function declaration.', () => {
        function toBeParsed(it, parses, me){};
        test(toBeParsed);
    });

    it('Parses a functional expression.', () => {
        const toBeParsed = function(it, parses, me){};
        test(toBeParsed);
    });

    it('Parses an arrow function', () => {
        const toBeParsed = (it, parses, me) => {};
        test(toBeParsed);
    });

    // ================= cases not currently handled ========================

    // It blows up on this type of messing. TBH if you do this it deserves to 
    // fail  On a tech note the params are pulled down in the function similar 
    // to how destructuring is handled by the ast.
    it('Parses complex default params', () => {
        function toBeParsed(it=4*(5/3), parses, me) {}
        test(toBeParsed);
    });

    // This passes back ['_ref'] as the params of the function. The _ref is a 
    // pointer to an VariableDeclarator where the ? happens.
    it('Parses object destructuring param definitions.' () => {
        function toBeParsed ({it, parses, me}){}
        test(toBeParsed);
    });

    it('Parses object destructuring param definitions.' () => {
        function toBeParsed ([it, parses, me]){}
        test(toBeParsed);
    });

    // Classes while similar from an end result point of view to function
    // declarations are handled completely differently in the JS AST. 
    it('Parses a class constructor when passed through', () => {
        class ToBeParsed {
            constructor(it, parses, me) {}
        }
        test(ToBeParsed);
    });
});

Depending on what you want to use it for ES6 Proxies and destructuring may be your best bet. For example if you wanted to use it for dependency injection (using the names of the params) then you can do it as follows:

class GuiceJs {
    constructor() {
        this.modules = {}
    }
    resolve(name) {
        return this.getInjector()(this.modules[name]);
    }
    addModule(name, module) {
        this.modules[name] = module;
    }
    getInjector() {
        var container = this;

        return (klass) => {
            console.log(klass);
            var paramParser = new Proxy({}, {
                // The `get` handler is invoked whenever a get-call for
                // `injector.*` is made. We make a call to an external service
                // to actually hand back in the configured service. The proxy
                // allows us to bypass parsing the function params using
                // taditional regex or even the newer parser.
                get: (target, name) => container.resolve(name),

                // You shouldn't be able to set values on the injector.
                set: (target, name, value) => {
                    throw new Error(`Don't try to set ${name}! `);
                }
            })
            return new klass(paramParser);
        }
    }
}

It's not the most advanced resolver out there but it gives an idea of how you can use a Proxy to handle it if you want to use args parser for simple DI. There is however one slight caveat in this approach. We need to use destructuring assignments instead of normal params. When we pass in the injector proxy the destructuring is the same as calling the getter on the object.

class App {
   constructor({tweeter, timeline}) {
        this.tweeter = tweeter;
        this.timeline = timeline;
    }
}

class HttpClient {}

class TwitterApi {
    constructor({client}) {
        this.client = client;
    }
}

class Timeline {
    constructor({api}) {
        this.api = api;
    }
}

class Tweeter {
    constructor({api}) {
        this.api = api;
    }
}

// Ok so now for the business end of the injector!
const di = new GuiceJs();

di.addModule('client', HttpClient);
di.addModule('api', TwitterApi);
di.addModule('tweeter', Tweeter);
di.addModule('timeline', Timeline);
di.addModule('app', App);

var app = di.resolve('app');
console.log(JSON.stringify(app, null, 4));

This outputs the following:

{
    "tweeter": {
        "api": {
            "client": {}
        }
    },
    "timeline": {
        "api": {
            "client": {}
        }
    }
}

Its wired up the entire application. The best bit is that the app is easy to test (you can just instantiate each class and pass in mocks/stubs/etc). Also if you need to swap out implementations, you can do that from a single place. All this is possible because of JS Proxy objects.

Note: There is a lot of work that would need to be done to this before it would be ready for production use but it does give an idea of what it would look like.

It's a bit late in the answer but it may help others who are thinking of the same thing.

JSON_UNESCAPED_UNICODE was added in PHP 5.4 so it looks like you need upgrade your version of PHP to take advantage of it. 5.4 is not released yet though! :(

There is a 5.4 alpha release candidate on QA though if you want to play on your development machine.

Essentially:

history.pushState('data', '', 'http://your-domain/path');

You can manipulate the history object to make this work.

It only works on the same domain, but since you're satisfied with using the hash tag approach, that shouldn't matter.

Obviously would need to be cross-browser tested, but since that was posted on the Opera forum I'm safe to assume it would work in Opera, and I just tested it in Chrome and it worked fine.

I imagine this forum posting, which I quote fully below, should answer the question.

Inside a procedure, function, or trigger definition, or in a dynamic SQL statement (embedded in a host program):

BEGIN ATOMIC
 DECLARE example VARCHAR(15) ;
 SET example = 'welcome' ;
 SELECT *
 FROM   tablename
 WHERE  column1 = example ;
END

or (in any environment):

WITH t(example) AS (VALUES('welcome'))
SELECT *
FROM   tablename, t
WHERE  column1 = example

or (although this is probably not what you want, since the variable needs to be created just once, but can be used thereafter by everybody although its content will be private on a per-user basis):

CREATE VARIABLE example VARCHAR(15) ;
SET example = 'welcome' ;
SELECT *
FROM   tablename
WHERE  column1 = example ;

Try this Method

dataGridView1.DataSource = dt;
dt.Rows.Clear();

Another interesting way when you use ES6 arrow function syntax:

x = ['a', 'a', 'a', 'a']
!x.filter(e=>e!==x[0])[0]  // true

x = ['a', 'a', 'b', 'a']
!x.filter(e=>e!==x[0])[0] // false

x = []
!x.filter(e=>e!==x[0])[0]  // true

And when you don't want to reuse the variable for array (x):

!['a', 'a', 'a', 'a'].filter((e,i,a)=>e!==a[0])[0]    // true

IMO previous poster who used array.every(...) has the cleanest solution.

I'm expecting, as Rohit Vats mentioned in his Comment too, that you have a wrong structure in your DataTable.

Try something like this:

  var t = new DataTable();

  // create column header
  foreach ( string s in identifiders ) {
    t.Columns.Add(new DataColumn(s)); // <<=== i'm expecting you don't have defined any DataColumns, haven't you?
  }

  // Add data to DataTable
  for ( int lineNumber = identifierLineNumber; lineNumber < lineCount; lineNumber++ ) {
    DataRow newRow = t.NewRow();
    for ( int column = 0; column < identifierCount; column++ ) {
      newRow[column] = fileContent.ElementAt(lineNumber)[column];
    }
    t.Rows.Add(newRow);
  }

  return t.DefaultView;

I have used this DataTable in a ValueConverter and it works like a charm with the following binding.

xaml:

 <DataGrid AutoGenerateColumns="True" ItemsSource="{Binding Path=FileContent, Converter={StaticResource dataGridConverter}}" />

So what it does, the ValueConverter transforms my bounded data (what ever it is, in my case it's a List<string[]>) into a DataTable, as the code above shows, and passes this DataTable to the DataGrid. With specified data columns the data grid can generate the needed columns and visualize them.

To say it in a nutshell, in my case the binding to a DataTable works like a charm.

Easy way to parse the xml is to use the LINQ to XML

For reading this file, you can use the following code:

public void Read(string  fileName)
{
    XDocument doc = XDocument.Load(fileName);

    foreach (XElement el in doc.Root.Elements())
    {
        Console.WriteLine("{0} {1}", el.Name, el.Attribute("id").Value);
        Console.WriteLine("  Attributes:");
        foreach (XAttribute attr in el.Attributes())
            Console.WriteLine("    {0}", attr);
        Console.WriteLine("  Elements:");

        foreach (XElement element in el.Elements())
            Console.WriteLine("    {0}: {1}", element.Name, element.Value);
    }
}

json = " { \"success\" : false, \"errors\": { \"text\" : \"??????!\" } }";            
return new MemoryStream(Encoding.UTF8.GetBytes(json));

Here are conversion method for both ways. this = instance of your class

public string ToXML()
    {
        using(var stringwriter = new System.IO.StringWriter())
        { 
            var serializer = new XmlSerializer(this.GetType());
            serializer.Serialize(stringwriter, this);
            return stringwriter.ToString();
        }
    }

 public static YourClass LoadFromXMLString(string xmlText)
    {
        using(var stringReader = new System.IO.StringReader(xmlText))
        {
            var serializer = new XmlSerializer(typeof(YourClass ));
            return serializer.Deserialize(stringReader) as YourClass ;
        }
    }

This is really more of a serverfault-type question, but you can use netstat.

something like:

 # netstat -lpnt | grep 6000 | grep ssh

This will tell you if there's an ssh process listening on the specified port. it will also tell you the PID of the process.

If you really want to double-check that the ssh process was started with the right options, you can then look up the process by PID in something like

# ps aux | grep PID

The latest dwr (http://directwebremoting.org/dwr/index.html) has ajax file uploads, complete with examples and nice stuff for users (like progress indicators and such).

It looks pretty nifty and dwr is fairly easy to use in general so this will be pretty good as well.

A simple way using std::next_permutation:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
    int n, r;
    std::cin >> n;
    std::cin >> r;

    std::vector<bool> v(n);
    std::fill(v.end() - r, v.end(), true);

    do {
        for (int i = 0; i < n; ++i) {
            if (v[i]) {
                std::cout << (i + 1) << " ";
            }
        }
        std::cout << "\n";
    } while (std::next_permutation(v.begin(), v.end()));
    return 0;
}

or a slight variation that outputs the results in an easier to follow order:

#include <iostream>
#include <algorithm>
#include <vector>

int main() {
   int n, r;
   std::cin >> n;
   std::cin >> r;

   std::vector<bool> v(n);
   std::fill(v.begin(), v.begin() + r, true);

   do {
       for (int i = 0; i < n; ++i) {
           if (v[i]) {
               std::cout << (i + 1) << " ";
           }
       }
       std::cout << "\n";
   } while (std::prev_permutation(v.begin(), v.end()));
   return 0;
}

A bit of explanation:

It works by creating a "selection array" (v), where we place r selectors, then we create all permutations of these selectors, and print the corresponding set member if it is selected in in the current permutation of v.

You can implement it if you note that for each level r you select a number from 1 to n.

In C++, we need to 'manually' keep the state between calls that produces results (a combination): so, we build a class that on construction initialize the state, and has a member that on each call returns the combination while there are solutions: for instance

#include <iostream>
#include <iterator>
#include <vector>
#include <cstdlib>

using namespace std;

struct combinations
{
    typedef vector<int> combination_t;

    // initialize status
   combinations(int N, int R) :
       completed(N < 1 || R > N),
       generated(0),
       N(N), R(R)
   {
       for (int c = 1; c <= R; ++c)
           curr.push_back(c);
   }

   // true while there are more solutions
   bool completed;

   // count how many generated
   int generated;

   // get current and compute next combination
   combination_t next()
   {
       combination_t ret = curr;

       // find what to increment
       completed = true;
       for (int i = R - 1; i >= 0; --i)
           if (curr[i] < N - R + i + 1)
           {
               int j = curr[i] + 1;
               while (i <= R-1)
                   curr[i++] = j++;
               completed = false;
               ++generated;
               break;
           }

       return ret;
   }

private:

   int N, R;
   combination_t curr;
};

int main(int argc, char **argv)
{
    int N = argc >= 2 ? atoi(argv[1]) : 5;
    int R = argc >= 3 ? atoi(argv[2]) : 2;
    combinations cs(N, R);
    while (!cs.completed)
    {
        combinations::combination_t c = cs.next();
        copy(c.begin(), c.end(), ostream_iterator<int>(cout, ","));
        cout << endl;
    }
    return cs.generated;
}

The purrr package has a lot of handy functions for working on lists. The flatten command can clean up unwanted nesting.

resultsa <- list(1,2,3,4,5)
resultsb <- list(6,7,8,9,10)
resultsc <- list(11,12,13,14,15)

nested_outlist <- list(resultsa, resultsb, resultsc)
outlist <- purrr::flatten(nested_outlist)

Overview

Why do we need the copy-and-swap idiom?

Any class that manages a resource (a wrapper, like a smart pointer) needs to implement The Big Three. While the goals and implementation of the copy-constructor and destructor are straightforward, the copy-assignment operator is arguably the most nuanced and difficult. How should it be done? What pitfalls need to be avoided?

The copy-and-swap idiom is the solution, and elegantly assists the assignment operator in achieving two things: avoiding code duplication, and providing a strong exception guarantee.

How does it work?

Conceptually, it works by using the copy-constructor's functionality to create a local copy of the data, then takes the copied data with a swap function, swapping the old data with the new data. The temporary copy then destructs, taking the old data with it. We are left with a copy of the new data.

In order to use the copy-and-swap idiom, we need three things: a working copy-constructor, a working destructor (both are the basis of any wrapper, so should be complete anyway), and a swap function.

A swap function is a non-throwing function that swaps two objects of a class, member for member. We might be tempted to use std::swap instead of providing our own, but this would be impossible; std::swap uses the copy-constructor and copy-assignment operator within its implementation, and we'd ultimately be trying to define the assignment operator in terms of itself!

(Not only that, but unqualified calls to swap will use our custom swap operator, skipping over the unnecessary construction and destruction of our class that std::swap would entail.)

An in-depth explanation

The goal

Let's consider a concrete case. We want to manage, in an otherwise useless class, a dynamic array. We start with a working constructor, copy-constructor, and destructor:

#include <algorithm> // std::copy
#include <cstddef> // std::size_t

class dumb_array
{
public:
    // (default) constructor
    dumb_array(std::size_t size = 0)
        : mSize(size),
          mArray(mSize ? new int[mSize]() : nullptr)
    {
    }

    // copy-constructor
    dumb_array(const dumb_array& other)
        : mSize(other.mSize),
          mArray(mSize ? new int[mSize] : nullptr),
    {
        // note that this is non-throwing, because of the data
        // types being used; more attention to detail with regards
        // to exceptions must be given in a more general case, however
        std::copy(other.mArray, other.mArray + mSize, mArray);
    }

    // destructor
    ~dumb_array()
    {
        delete [] mArray;
    }

private:
    std::size_t mSize;
    int* mArray;
};

This class almost manages the array successfully, but it needs operator= to work correctly.

A failed solution

Here's how a naive implementation might look:

// the hard part
dumb_array& operator=(const dumb_array& other)
{
    if (this != &other) // (1)
    {
        // get rid of the old data...
        delete [] mArray; // (2)
        mArray = nullptr; // (2) *(see footnote for rationale)

        // ...and put in the new
        mSize = other.mSize; // (3)
        mArray = mSize ? new int[mSize] : nullptr; // (3)
        std::copy(other.mArray, other.mArray + mSize, mArray); // (3)
    }

    return *this;
}

And we say we're finished; this now manages an array, without leaks. However, it suffers from three problems, marked sequentially in the code as (n).

1. The first is the self-assignment test. This check serves two purposes: it's an easy way to prevent us from running needless code on self-assignment, and it protects us from subtle bugs (such as deleting the array only to try and copy it). But in all other cases it merely serves to slow the program down, and act as noise in the code; self-assignment rarely occurs, so most of the time this check is a waste. It would be better if the operator could work properly without it.

2. The second is that it only provides a basic exception guarantee. If new int[mSize] fails, *this will have been modified. (Namely, the size is wrong and the data is gone!) For a strong exception guarantee, it would need to be something akin to:

   dumb_array& operator=(const dumb_array& other)
   {
       if (this != &other) // (1)
       {
           // get the new data ready before we replace the old
           std::size_t newSize = other.mSize;
           int* newArray = newSize ? new int[newSize]() : nullptr; // (3)
           std::copy(other.mArray, other.mArray + newSize, newArray); // (3)
   
           // replace the old data (all are non-throwing)
           delete [] mArray;
           mSize = newSize;
           mArray = newArray;
       }
   
       return *this;
   }
   

3. The code has expanded! Which leads us to the third problem: code duplication. Our assignment operator effectively duplicates all the code we've already written elsewhere, and that's a terrible thing.

In our case, the core of it is only two lines (the allocation and the copy), but with more complex resources this code bloat can be quite a hassle. We should strive to never repeat ourselves.

(One might wonder: if this much code is needed to manage one resource correctly, what if my class manages more than one? While this may seem to be a valid concern, and indeed it requires non-trivial try/catch clauses, this is a non-issue. That's because a class should manage one resource only!)

A successful solution

As mentioned, the copy-and-swap idiom will fix all these issues. But right now, we have all the requirements except one: a swap function. While The Rule of Three successfully entails the existence of our copy-constructor, assignment operator, and destructor, it should really be called "The Big Three and A Half": any time your class manages a resource it also makes sense to provide a swap function.

We need to add swap functionality to our class, and we do that as follows†:

class dumb_array
{
public:
    // ...

    friend void swap(dumb_array& first, dumb_array& second) // nothrow
    {
        // enable ADL (not necessary in our case, but good practice)
        using std::swap;

        // by swapping the members of two objects,
        // the two objects are effectively swapped
        swap(first.mSize, second.mSize);
        swap(first.mArray, second.mArray);
    }

    // ...
};

(Here is the explanation why public friend swap.) Now not only can we swap our dumb_array's, but swaps in general can be more efficient; it merely swaps pointers and sizes, rather than allocating and copying entire arrays. Aside from this bonus in functionality and efficiency, we are now ready to implement the copy-and-swap idiom.

Without further ado, our assignment operator is:

dumb_array& operator=(dumb_array other) // (1)
{
    swap(*this, other); // (2)

    return *this;
}

And that's it! With one fell swoop, all three problems are elegantly tackled at once.

Why does it work?

We first notice an important choice: the parameter argument is taken by-value. While one could just as easily do the following (and indeed, many naive implementations of the idiom do):

dumb_array& operator=(const dumb_array& other)
{
    dumb_array temp(other);
    swap(*this, temp);

    return *this;
}

We lose an important optimization opportunity. Not only that, but this choice is critical in C++11, which is discussed later. (On a general note, a remarkably useful guideline is as follows: if you're going to make a copy of something in a function, let the compiler do it in the parameter list.‡)

Either way, this method of obtaining our resource is the key to eliminating code duplication: we get to use the code from the copy-constructor to make the copy, and never need to repeat any bit of it. Now that the copy is made, we are ready to swap.

Observe that upon entering the function that all the new data is already allocated, copied, and ready to be used. This is what gives us a strong exception guarantee for free: we won't even enter the function if construction of the copy fails, and it's therefore not possible to alter the state of *this. (What we did manually before for a strong exception guarantee, the compiler is doing for us now; how kind.)

At this point we are home-free, because swap is non-throwing. We swap our current data with the copied data, safely altering our state, and the old data gets put into the temporary. The old data is then released when the function returns. (Where upon the parameter's scope ends and its destructor is called.)

Because the idiom repeats no code, we cannot introduce bugs within the operator. Note that this means we are rid of the need for a self-assignment check, allowing a single uniform implementation of operator=. (Additionally, we no longer have a performance penalty on non-self-assignments.)

And that is the copy-and-swap idiom.

What about C++11?

The next version of C++, C++11, makes one very important change to how we manage resources: the Rule of Three is now The Rule of Four (and a half). Why? Because not only do we need to be able to copy-construct our resource, we need to move-construct it as well.

Luckily for us, this is easy:

class dumb_array
{
public:
    // ...

    // move constructor
    dumb_array(dumb_array&& other) noexcept ††
        : dumb_array() // initialize via default constructor, C++11 only
    {
        swap(*this, other);
    }

    // ...
};

What's going on here? Recall the goal of move-construction: to take the resources from another instance of the class, leaving it in a state guaranteed to be assignable and destructible.

So what we've done is simple: initialize via the default constructor (a C++11 feature), then swap with other; we know a default constructed instance of our class can safely be assigned and destructed, so we know other will be able to do the same, after swapping.

(Note that some compilers do not support constructor delegation; in this case, we have to manually default construct the class. This is an unfortunate but luckily trivial task.)

Why does that work?

That is the only change we need to make to our class, so why does it work? Remember the ever-important decision we made to make the parameter a value and not a reference:

dumb_array& operator=(dumb_array other); // (1)

Now, if other is being initialized with an rvalue, it will be move-constructed. Perfect. In the same way C++03 let us re-use our copy-constructor functionality by taking the argument by-value, C++11 will automatically pick the move-constructor when appropriate as well. (And, of course, as mentioned in previously linked article, the copying/moving of the value may simply be elided altogether.)

And so concludes the copy-and-swap idiom.

Footnotes

*Why do we set mArray to null? Because if any further code in the operator throws, the destructor of dumb_array might be called; and if that happens without setting it to null, we attempt to delete memory that's already been deleted! We avoid this by setting it to null, as deleting null is a no-operation.

†There are other claims that we should specialize std::swap for our type, provide an in-class swap along-side a free-function swap, etc. But this is all unnecessary: any proper use of swap will be through an unqualified call, and our function will be found through ADL. One function will do.

‡The reason is simple: once you have the resource to yourself, you may swap and/or move it (C++11) anywhere it needs to be. And by making the copy in the parameter list, you maximize optimization.

††The move constructor should generally be noexcept, otherwise some code (e.g. std::vector resizing logic) will use the copy constructor even when a move would make sense. Of course, only mark it noexcept if the code inside doesn't throw exceptions.

Probably the shortest version:

[System.Collections.ArrayList]$someArray

It is also faster because it does not call relatively expensive New-Object.

/* (opener) */ (closer)

for example,

<html>
 /*<p>Commented P Tag </p>*/
<html>

On Mac it's PyCharm => Preferences... => Tools => Terminal => Activate virtualenv, which should be enabled by default.

I had the same issue using an older version of Fancybox. Upgrading to v3 will solve your problem OR you can just add:

html, body {
    -webkit-overflow-scrolling : touch !important;
    overflow: auto !important;
    height: 100% !important;
}

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

To repeat 7 times, try to use a an array with length=7, then track it by $index:

<span ng-repeat="a in (((b=[]).length=7)&&b) track by $index" ng-bind="$index + 1 + ', '"></span>

b=[] create an empty Array «b»,
.length=7 set it's size to «7»,
&&b let the new Array «b» be available to ng-repeat,
track by $index where «$index» is the position of iteration.
ng-bind="$index + 1" display starting at 1.

To repeat X times:
just replace 7 by X.

A String is an immutable character array.

A StringBuffer is a mutable character array. Often converted back to String when done mutating.

Since both are an array, the maximum size for both is equal to the maximum size of an integer, which is 2^31-1 (see JavaDoc, also check out the JavaDoc for both String and StringBuffer).This is because the .length argument of an array is a primitive int. (See Arrays).

It's a linker error. ld is the linker, so if you get an error message ending with "ld returned 1 exit status", that tells you that it's a linker error.

The error message tells you that none of the object files you're linking against contains a definition for avergecolumns. The reason for that is that the function you've defined is called averagecolumns (in other words: you misspelled the function name when calling the function (and presumably in the header file as well - otherwise you'd have gotten a different error at compile time)).

Check out this snippet:

Private Sub openDialog()
    Dim fd As Office.FileDialog

    Set fd = Application.FileDialog(msoFileDialogFilePicker)

   With fd

      .AllowMultiSelect = False

      ' Set the title of the dialog box.
      .Title = "Please select the file."

      ' Clear out the current filters, and add our own.
      .Filters.Clear
      .Filters.Add "Excel 2003", "*.xls"
      .Filters.Add "All Files", "*.*"

      ' Show the dialog box. If the .Show method returns True, the
      ' user picked at least one file. If the .Show method returns
      ' False, the user clicked Cancel.
      If .Show = True Then
        txtFileName = .SelectedItems(1) 'replace txtFileName with your textbox

      End If
   End With
End Sub

I think this is what you are asking for.

This answer simply extends @Andy Hayden's, making it resilient to when numeric fields are nan, and wrapping it up into a function.

import pandas as pd
import numpy as np


def diff_pd(df1, df2):
    """Identify differences between two pandas DataFrames"""
    assert (df1.columns == df2.columns).all(), \
        "DataFrame column names are different"
    if any(df1.dtypes != df2.dtypes):
        "Data Types are different, trying to convert"
        df2 = df2.astype(df1.dtypes)
    if df1.equals(df2):
        return None
    else:
        # need to account for np.nan != np.nan returning True
        diff_mask = (df1 != df2) & ~(df1.isnull() & df2.isnull())
        ne_stacked = diff_mask.stack()
        changed = ne_stacked[ne_stacked]
        changed.index.names = ['id', 'col']
        difference_locations = np.where(diff_mask)
        changed_from = df1.values[difference_locations]
        changed_to = df2.values[difference_locations]
        return pd.DataFrame({'from': changed_from, 'to': changed_to},
                            index=changed.index)

So with your data (slightly edited to have a NaN in the score column):

df1 = pd.read_table(DF1, sep='\s+', index_col='id')
df2 = pd.read_table(DF2, sep='\s+', index_col='id')
diff_pd(df1, df2)

Output:

A simpler implementation using Kotlin

fun PackageManager.isAppInstalled(packageName: String): Boolean =
        getInstalledApplications(PackageManager.GET_META_DATA)
                .firstOrNull { it.packageName == packageName } != null

And call it like this (seeking for Spotify app):

packageManager.isAppInstalled("com.spotify.music")

Pass it as an argument to Date():

var st = "date in some format"
var dt = new Date(st);

You can access the date, month, year using, for example: dt.getMonth().

As it was mentioned @PropertySource doesn't load yaml file. As a workaround load the file on your own and add loaded properties to Environment.

Implemement ApplicationContextInitializer:

public class YamlFileApplicationContextInitializer implements ApplicationContextInitializer<ConfigurableApplicationContext> {
  @Override
  public void initialize(ConfigurableApplicationContext applicationContext) {
    try {
        Resource resource = applicationContext.getResource("classpath:file.yml");
        YamlPropertySourceLoader sourceLoader = new YamlPropertySourceLoader();
        PropertySource<?> yamlTestProperties = sourceLoader.load("yamlTestProperties", resource, null);
        applicationContext.getEnvironment().getPropertySources().addFirst(yamlTestProperties);
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
  }
}

Add your initializer to your test:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class, initializers = YamlFileApplicationContextInitializer.class)
public class SimpleTest {
  @Test
  public test(){
    // test your properties
  }
}

I did it this way and it worked for me like a charm.

var data = [{ id: 0, text: 'enhancement' }, { id: 1, text: 'bug' }, { id: 2, 

    text: 'duplicate' }, { id: 3, text: 'invalid' }, { id: 4, text: 'wontfix' }];

    $(".js-example-data-array").select2({
      data: data
    })

We will consider first List type is String and want to convert it to Integer type of List.

List<String> origList = new ArrayList<>(); // assume populated

Add values in the original List.

origList.add("1");
origList.add("2");
    origList.add("3");
    origList.add("4");
    origList.add("8");

Create target List of Integer Type

List<Integer> targetLambdaList = new ArrayList<Integer>();
targetLambdaList=origList.stream().map(Integer::valueOf).collect(Collectors.toList());

Print List values using forEach:

    targetLambdaList.forEach(System.out::println);

(I think the id attribute needs to start with a letter. Could be wrong.)

You could go for event delegation...

<div onClick="reply_click()">
    <button id="1"></button>
    <button id="2"></button>
    <button id="3"></button>
</div>

function reply_click(e) {
    e = e || window.event;
    e = e.target || e.srcElement;
    if (e.nodeName === 'BUTTON') {
        alert(e.id);
    }
}

...but that requires you to be relatively comfortable with the wacky event model.

Works with jQuery, tested on Ipad v.5.1.1

$('video').get(0).play();

You have to append/remove the video element from the page.

This website has some nice examples for using spring's RestTemplate. Here is a code example of how it can work to get a simple object:

private static void getEmployees()
{
    final String uri = "http://localhost:8080/springrestexample/employees.xml";

    RestTemplate restTemplate = new RestTemplate();
    String result = restTemplate.getForObject(uri, String.class);

    System.out.println(result);
}

I think the Wikipedia-article on Deprecation answers this one pretty well:

In the process of authoring computer software, its standards or documentation, deprecation is a status applied to software features to indicate that they should be avoided, typically because they have been superseded. Although deprecated features remain in the software, their use may raise warning messages recommending alternative practices, and deprecation may indicate that the feature will be removed in the future. Features are deprecated—rather than immediately removed—in order to provide backward compatibility, and give programmers who have used the feature time to bring their code into compliance with the new standard.

The quoting rules are painful. I think you want:

SELECT nextval('foo."SQ_ID"');

to prevent case-folding of SQ_ID.

If you tried to "make install" in your project directory with this error you can try it:

rm -rf ./node_modules
npm cache clear
npm remove sails

then you can try to "make install"

If you have the "npm ERR! enoent ENOENT: no such file or directory, chmod '.../djam-backend/node_modules/js-beautify/js/bin/css-beautify.js'" then you can try to install some previous version of the js-beautify, more comments: https://github.com/beautify-web/js-beautify/issues/1247

"dependencies": {
  ...
  "js-beautify": "1.6.14"
  ...
}

and the run "make install". It seem works in case if you have not other dependencies that requires higher version (1.7.0) in this case you must downgrade this packages also in the packages.json.

or

In ES6 you can do this:

let cake = '';

let pan = {
  [cake]: '',
};

// Output -> { '': '' }

Old Way

let cake = '';
let pan = {};
pan[cake] = '';

// Output -> { '': '' }

FYI, if you want to create an Installer package in VS2010, unfortunately it only targets .NET 4. To work around this, you have to add NET 4.5 as a launch condition.

Add the following in to the Launch Conditions of the installer (Right click, View, Launch Conditions).

In "Search Target Machine", right click and select "Add Registry Search".

Property: REGISTRYVALUE1
RegKey: Software\Microsoft\NET Framework Setup\NDP\v4\Full
Root: vsdrrHKLM
Value: Release

Add new "Launch Condition":

Condition: REGISTRYVALUE1>="#378389"
InstallUrl: http://www.microsoft.com/en-gb/download/details.aspx?id=30653
Message: Setup requires .NET Framework 4.5 to be installed.

Where:

378389 = .NET Framework 4.5

378675 = .NET Framework 4.5.1 installed with Windows 8.1

378758 = .NET Framework 4.5.1 installed on Windows 8, Windows 7 SP1, or Windows Vista SP2

379893 = .NET Framework 4.5.2

Launch condition reference: http://msdn.microsoft.com/en-us/library/vstudio/xxyh2e6a(v=vs.100).aspx

If your main concern is the memory usage of your Firefox extension, I suggest checking with Mozilla developers.

Mozilla provides on its wiki a list of tools to analyze memory leaks.

This works for me:

pip install numpy --upgrade

All the technical talking is overcomplicating the concept.

If you put GC into C++ for all the memory automatically then consider something like a web browser. The web browser must load a full web document AND run web scripts. You can store web script variables in the document tree. In a BIG document in a browser with lots of tabs open, it means that every time the GC must do a full collection it must also scan all the document elements.

On most computers this means that PAGE FAULTS will occur. So the main reason, to answer the question is that PAGE FAULTS will occur. You will know this as when your PC starts making lots of disk access. This is because the GC must touch lots of memory in order to prove invalid pointers. When you have a bona fide application using lots of memory, having to scan all objects every collection is havoc because of the PAGE FAULTS. A page fault is when virtual memory needs to get read back into RAM from disk.

So the correct solution is to divide an application into the parts that need GC and the parts that do not. In the case of the web browser example above, if the document tree was allocated with malloc, but the javascript ran with GC, then every time the GC kicks in it only scans a small portion of memory and all PAGED OUT elements of the memory for the document tree does not need to get paged back in.

To further understand this problem, look up on virtual memory and how it is implemented in computers. It is all about the fact that 2GB is available to the program when there is not really that much RAM. On modern computers with 2GB RAM for a 32BIt system it is not such a problem provided only one program is running.

As an additional example, consider a full collection that must trace all objects. First you must scan all objects reachable via roots. Second scan all the objects visible in step 1. Then scan waiting destructors. Then go to all the pages again and switch off all invisible objects. This means that many pages might get swapped out and back in multiple times.

So my answer to bring it short is that the number of PAGE FAULTS which occur as a result of touching all the memory causes full GC for all objects in a program to be unfeasible and so the programmer must view GC as an aid for things like scripts and database work, but do normal things with manual memory management.

And the other very important reason of course is global variables. In order for the collector to know that a global variable pointer is in the GC it would require specific keywords, and thus existing C++ code would not work.

In lightsail a virtual machine, SSD-based storage, data transfer, DNS management, and a static IP are all offered as a package. Whereas in normal case you provision an EC2 instance and then setup the rest of these things.Also Bandwidth included in the price, no security groups to set up, no need to worry about EBS volumes sizing.

& and | are bitwise operators that can operate on both integer and Boolean arguments, and && and || are logical operators that can operate only on Boolean arguments. In many languages, if both arguments are Boolean, the key difference is that the logical operators will perform short circuit evaluation and not evaluate the second argument if the first argument is enough to determine the answer (e.g. in the case of &&, if the first argument is false, the second argument is irrelevant).

Why should you learn Python Programming Language?

Python offers a stepping stone into the world of programming. Even though Python Programming Language has been around for 25 years, it is still rising in popularity. Some of the biggest advantage of Python are it's

• Easy to Read & Easy to Learn
• Very productive or small as well as big projects
• Big libraries for many things

What is Python Programming Language used for?

As a general purpose programming language, Python can be used for multiple things. Python can be easily used for small, large, online and offline projects. The best options for utilizing Python are web development, simple scripting and data analysis. Below are a few examples of what Python will let you do:

Web Development:

You can use Python to create web applications on many levels of complexity. There are many excellent Python web frameworks including, Pyramid, Django and Flask, to name a few.

Data Analysis:

Python is the leading language of choice for many data scientists. Python has grown in popularity, within this field, due to its excellent libraries including; NumPy and Pandas and its superb libraries for data visualisation like Matplotlib and Seaborn.

Machine Learning:

What if you could predict customer satisfaction or analyse what factors will affect household pricing or to predict stocks over the next few days, based on previous years data? There are many wonderful libraries implementing machine learning algorithms such as Scikit-Learn, NLTK and TensorFlow.

Computer Vision:

You can do many interesting things such as Face detection, Color detection while using Opencv and Python.

Internet Of Things With Raspberry Pi:

Raspberry Pi is a very tiny and affordable computer which was developed for education and has gained enormous popularity among hobbyists with do-it-yourself hardware and automation. You can even build a robot and automate your entire home. Raspberry Pi can be used as the brain for your robot in order to perform various actions and/or react to the environment. The coding on a Raspberry Pi can be performed using Python. The Possibilities are endless!

Game Development:

Create a video game using module Pygame. Basically, you use Python to write the logic of the game. PyGame applications can run on Android devices.

Web Scraping:

If you need to grab data from a website but the site does not have an API to expose data, use Python to scraping data.

Writing Scripts:

If you're doing something manually and want to automate repetitive stuff, such as emails, it's not difficult to automate once you know the basics of this language.

Browser Automation:

Perform some neat things such as opening a browser and posting a Facebook status, you can do it with Selenium with Python.

GUI Development:

Build a GUI application (desktop app) using Python modules Tkinter, PyQt to support it.

Rapid Prototyping:

Python has libraries for just about everything. Use it to quickly built a (lower-performance, often less powerful) prototype. Python is also great for validating ideas or products for established companies and start-ups alike.

Python can be used in so many different projects. If you're a programmer looking for a new language, you want one that is growing in popularity. As a newcomer to programming, Python is the perfect choice for learning quickly and easily.

If all you need is to clear the screen, this is probably good enough. The problem is there's not even a 100% cross platform way of doing this across linux versions. The problem is the implementations of the terminal all support slightly different things. I'm fairly sure that "clear" will work everywhere. But the more "complete" answer is to use the xterm control characters to move the cursor, but that requires xterm in and of itself.

Without knowing more of your problem, your solution seems good enough.

The openssl documentation says that file supplied as the -in argument must be in PEM format.

Turns out that, contrary to the CA's manual, the certificate returned by the CA which I stored in myCert.cer is not PEM format rather it is PKCS7.

In order to create my .p12, I had to first convert the certificate to PEM:

openssl pkcs7 -in myCert.cer -print_certs -out certs.pem

and then execute

openssl pkcs12 -export -out keyStore.p12 -inkey myKey.pem -in certs.pem

To add one day to a date object:

var date = new Date();

// add a day
date.setDate(date.getDate() + 1);

I often use following command to spin my PHP Laravel framework :

$ php artisan serve --port=8080
or
$ php -S localhost:8080 -t public/

In above command : - Artisan is command-line interface included with Laravel which use serve to call built in php server

To Run with built-in web server.

 php -S <addr>:<port> -T

Here,
-S : Switch to Run with built-in web server.
-T : Switch to specify document root for built-in web server.

Many ways. DON'T use the most obvious one (%s with %) in real code, it's open to attacks.

Here copy-paste'd from pydoc of sqlite3:

# Never do this -- insecure!
symbol = 'RHAT'
c.execute("SELECT * FROM stocks WHERE symbol = '%s'" % symbol)

# Do this instead
t = ('RHAT',)
c.execute('SELECT * FROM stocks WHERE symbol=?', t)
print c.fetchone()

# Larger example that inserts many records at a time
purchases = [('2006-03-28', 'BUY', 'IBM', 1000, 45.00),
             ('2006-04-05', 'BUY', 'MSFT', 1000, 72.00),
             ('2006-04-06', 'SELL', 'IBM', 500, 53.00),
            ]
c.executemany('INSERT INTO stocks VALUES (?,?,?,?,?)', purchases)

More examples if you need:

# Multiple values single statement/execution
c.execute('SELECT * FROM stocks WHERE symbol=? OR symbol=?', ('RHAT', 'MSO'))
print c.fetchall()
c.execute('SELECT * FROM stocks WHERE symbol IN (?, ?)', ('RHAT', 'MSO'))
print c.fetchall()
# This also works, though ones above are better as a habit as it's inline with syntax of executemany().. but your choice.
c.execute('SELECT * FROM stocks WHERE symbol=? OR symbol=?', 'RHAT', 'MSO')
print c.fetchall()
# Insert a single item
c.execute('INSERT INTO stocks VALUES (?,?,?,?,?)', ('2006-03-28', 'BUY', 'IBM', 1000, 45.00))

Additionally, if you set a layout_weight, this supersedes the numStars attribute.

You can use PowerShell.

New-Service -Name "TestService" -BinaryPathName "C:\WINDOWS\System32\svchost.exe -k netsvcs"

find . -type f | 
sed -n "s/\(.*\)factory\.py$/& \1service\.py/p" | 
xargs -p -n 2 mv

eg will rename all files in the cwd with names ending in "factory.py" to be replaced with names ending in "service.py"

explanation:

1) in the sed cmd, the -n flag will suppress normal behavior of echoing input to output after the s/// command is applied, and the p option on s/// will force writing to output if a substitution is made. since a sub will only be made on match, sed will only have output for files ending in "factory.py"

2) in the s/// replacement string, we use "& " to interpolate the entire matching string, followed by a space character, into the replacement. because of this, it's vital that our RE matches the entire filename. after the space char, we use "\1service.py" to interpolate the string we gulped before "factory.py", followed by "service.py", replacing it. So for more complex transformations youll have to change the args to s/// (with an re still matching the entire filename)

example output:

foo_factory.py foo_service.py
bar_factory.py bar_service.py

3) we use xargs with -n 2 to consume the output of sed 2 delimited strings at a time, passing these to mv (i also put the -p option in there so you can feel safe when running this). voila.

Convert an iterable to a list may have a cost. Instead, to get the the first item, you can use:

next(iter(keys))

Or, if you want to iterate over all items, you can use:

items = iter(keys)
while True:
    try:
        item = next(items)
    except StopIteration as e:
        pass # finish

If the option -d works in your system, here's another way to do it. There is a caveat that it wouldn't account for leap years since I've considered 365 days per year.

date1yrs=`date -d "20100209" +%Y`
date1days=`date -d "20100209" +%j`
date2yrs=`date +%Y`
date2days=`date +%j`
diffyr=`expr $date2yrs - $date1yrs`
diffyr2days=`expr $diffyr \* 365`
diffdays=`expr $date2days - $date1days`
echo `expr $diffyr2days + $diffdays`

In some cases you can just use the flex-box property order.

Very simple:

.flex-item {
    order: 2;
}

Code snippet for implementing matching parenthesis using java.util.Stack data structure -

    //map for storing matching parenthesis pairs
    private static final Map<Character, Character> matchingParenMap = new HashMap<>();

    //set for storing opening parenthesis
    private static final Set<Character> openingParenSet = new HashSet<>();

    static {
         matchingParenMap.put(')','(');
         matchingParenMap.put(']','['); 
         matchingParenMap.put('}','{'); 
         openingParenSet.addAll(matchingParenMap.values());  
    }

    //check if parenthesis match
    public static boolean hasMatchingParen(String input) {
      try {
         //stack to store opening parenthesis
         Stack<Character> parenStack = new Stack<>();

         for(int i=0; i< input.length(); i++) {
            char ch = input.charAt(i);

            //if an opening parenthesis then push to the stack
            if(openingParenSet.contains(ch)) {
                 parenStack.push(ch);
            } 

            //for closing parenthesis
            if(matchingParenMap.containsKey(ch)) {
                 Character lastParen = parenStack.pop();
                 if(lastParen != matchingParenMap.get(ch)) {
                    return false;
                 } 
            }
         }

         //returns true if the stack is empty else false
         return parenStack.isEmpty();
       }
         catch(StackOverflowException s) {}
         catch(StackUnderflowException s1) {}
         return false;
    }

I have explained the code snippet and the algorithm used on blog http://hetalrachh.home.blog/2019/12/25/stack-data-structure/

As what I have understand on your question, this is what you want.

%Lf (note the capital L) is the format specifier for long doubles.

For plain doubles, either %e, %E, %f, %g or %G will do.

If you have a constraint to center the Stack View vertically inside the scroll view, just remove it.

Well to solve the problems of master password - the best approach is not to store the password anywhere, the application should encrypt passwords for itself - so that only it can decrypt them. So if I was using a .config file I would do the following, mySettings.config:

encryptTheseKeys=secretKey,anotherSecret

secretKey=unprotectedPasswordThatIputHere

anotherSecret=anotherPass

someKey=unprotectedSettingIdontCareAbout

so I would read in the keys that are mentioned in the encryptTheseKeys, apply the Brodwalls example from above on them and write them back to the file with a marker of some sort (lets say crypt:) to let the application know not to do it again, the output would look like this:

encryptTheseKeys=secretKey,anotherSecret

secretKey=crypt:ii4jfj304fjhfj934fouh938

anotherSecret=crypt:jd48jofh48h

someKey=unprotectedSettingIdontCareAbout

Just make sure to keep the originals in your own secure place...

If you'd like to track only failed logins, you can use the SQL Server Audit feature (available in SQL Server 2008 and above). You will need to add the SQL server instance you want to audit, and check the failed login operation to audit.

Note: tracking failed logins via SQL Server Audit has its disadvantages. For example - it doesn't provide the names of client applications used.

If you want to audit a client application name along with each failed login, you can use an Extended Events session.

To get you started, I recommend reading this article: http://www.sqlshack.com/using-extended-events-review-sql-server-failed-logins/

If the user clicks Cancel, a zero-length string is returned. You can't differentiate this from entering an empty string. You can however make your own custom InputBox class...

EDIT to properly differentiate between empty string and cancel, according to this answer.

Your example

Private Sub test()
    Dim result As String
    result = InputBox("Enter Date MM/DD/YYY", "Date Confirmation", Now)
    If StrPtr(result) = 0 Then
        MsgBox ("User canceled!")
    ElseIf result = vbNullString Then
        MsgBox ("User didn't enter anything!")
    Else
        MsgBox ("User entered " & result)
    End If
End Sub

Would tell the user they canceled when they delete the default string, or they click cancel.

to use parameters in aliases, i use this method:

alias myalias='function __myalias() { echo "Hello $*"; unset -f __myalias; }; __myalias'

its a self-destructive function wrapped in an alias, so it pretty much is the best of both worlds, and doesnt take up an extra line(s) in your definitions... which i hate, oh yeah and if you need that return value, you'll have to store it before calling unset, and then return the value using the "return" keyword in that self destructive function there:

alias myalias='function __myalias() { echo "Hello $*"; myresult=$?; unset -f __myalias; return $myresult; }; __myalias'

so..

you could, if you need to have that variable in there

alias mongodb='function __mongodb() { ./path/to/mongodb/$1; unset -f __mongodb; }; __mongodb'

of course...

alias mongodb='./path/to/mongodb/'

would actually do the same thing without the need for parameters, but like i said, if you wanted or needed them for some reason (for example, you needed $2 instead of $1), you would need to use a wrapper like that. If it is bigger than one line you might consider just writing a function outright since it would become more of an eyesore as it grew larger. Functions are great since you get all the perks that functions give (see completion, traps, bind, etc for the goodies that functions can provide, in the bash manpage).

I hope that helps you out :)

Try this code:

<form id="myform">
  <!-- form elements -->
  <a href="#" onclick="document.getElementById('myform').submit()">Submit</a>
</form>

But users with disabled JavaScript won't be able to submit the form, so you could add the following code:

<noscript>
  <input type="submit" value="Submit form!" />
</noscript>

The pattern \d might not be supported by your sed. Try [0-9] or [[:digit:]] instead.

To only print the actual match (not the entire matching line), use a substitution.

sed -n 's/.*\([0-9][0-9]*G[0-9][0-9]*\).*/\1/p'

std::find().

The map file maps the unminified file to the minified file. If you make changes in the unminified file, the changes will be automatically reflected to the minified version of the file.

Jquery VS javascript, I am completely against the OP in this question. Comparison happens with two similar things, not in such case.

Jquery is Javascript. A javascript library to reduce vague coding, collection commonly used javascript functions which has proven to help in efficient and fast coding.

Javascript is the source, the actual scripts that browser responds to.

As Get-Date returns a DateTime object you are able to compare them directly. An example:

(get-date 2010-01-02) -lt (get-date 2010-01-01)

will return false.

If you are working in Visual studio. You can try this fix

1. Unload your project from visual studio
2. Go to your project home directory and Open "csproj" file.

3. Add TypeScriptExperimentalDecorators to this section as shown in image

   

   4. Reload the project in Visual studio.

see more details at this location.

You can try this code

String[] stringA = new String[stringArrayList.size()];
stringArrayList.toArray(stringA)
System.out.println(stringA[0]);

In my case when I get this message IE suggest me to install add-on from Microsoft. After install problem solved.

My software:

If the to-be-updated component is not inside the same NamingContainer component (ui:repeat, h:form, h:dataTable, etc), then you need to specify the "absolute" client ID. Prefix with : (the default NamingContainer separator character) to start from root.

<p:ajax process="@this" update="count :subTotal"/>

To be sure, check the client ID of the subTotal component in the generated HTML for the actual value. If it's inside for example a h:form as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.

<p:ajax process="@this" update="count :formId:subTotal"/>

Space separation of IDs is more recommended as <f:ajax> doesn't support comma separation and starters would otherwise get confused.

The form's "on submit" handlers are called before the form is submitted. I don't know if there is a handler to be called after the form is submited. In the traditional non-Javascript sense the form submission will reload the page.

If you're writing a Chrome Extension and get this error, then be sure you have added the API's base URL to your manifest.json's permissions block, example:

"permissions": [
    "https://itunes.apple.com/"
]

git add . (add all files in this directory)

git add -all (add all files in all directories)

git add -N can be helpful for for listing which ones for later....

To do POST you'll need to have a form.

<form action="employee.action" method="post">
    <input type="submit" value="Employee1" />
</form>

There are some ways to post data with hyperlinks, but you'll need some javascript, and a form.

Some tricks: Make a link use POST instead of GET and How do you post data with a link

Edit: to load response on a frame you can target your form to your frame:

<form action="employee.action" method="post" target="myFrame">

if you have a given Date string with date and time .

for e.g String givenDateString = pojoModel.getDate()/* Format dd-MMM-yyyy hh:mm:ss */

use the following code to add an event with date and time to the calendar

Calendar cal = Calendar.getInstance();
cal.setTime(new SimpleDateFormat("dd-MMM-yyyy hh:mm:ss").parse(givenDateString));
Intent intent = new Intent(Intent.ACTION_EDIT);
intent.setType("vnd.android.cursor.item/event");
intent.putExtra("beginTime", cal.getTimeInMillis());
intent.putExtra("allDay", false);
intent.putExtra("rrule", "FREQ=YEARLY");
intent.putExtra("endTime",cal.getTimeInMillis() + 60 * 60 * 1000);
intent.putExtra("title", " Test Title");
startActivity(intent);

For enum type, I think this is a suitable way, and the difference between class is how to calculate hash value.

template <typename T>
struct EnumTypeHash {
  std::size_t operator()(const T& type) const {
    return static_cast<std::size_t>(type);
  }
};

enum MyEnum {};
class MyValue {};

std::unordered_map<MyEnum, MyValue, EnumTypeHash<MyEnum>> map_;

Short answer: You have to understand the difference and make choice depending on the code.

Long answer: In general I would rather try to avoid synchronize(this) to reduce contention but private locks add complexity you have to be aware of. So use the right synchronization for the right job. If you are not so experienced with multi-threaded programming I would rather stick to instance locking and read up on this topic. (That said: just using synchronize(this) does not automatically make your class fully thread-safe.) This is a not an easy topic but once you get used to it, the answer whether to use synchronize(this) or not comes naturally.

As it is announced in jQuery 1.11.0/2.1.0 Beta 2 Released the source map comment will be removed so the issue will not appear in newer versions of jQuery.

Here is the official announcement:

One of the changes we’ve made in this beta is to remove the sourcemap comment. Sourcemaps have proven to be a very problematic and puzzling thing to developers, generating scores of confused questions on forums like StackOverflow and causing users to think jQuery itself was broken.

Anyway, if you need to use a source map, it still be available:

We’ll still be generating and distributing sourcemaps, but you will need to add the appropriate sourcemap comment at the end of the minified file if the browser does not support manually associating map files (currently, none do). If you generate your own jQuery file using the custom build process, the sourcemap comment will be present in the minified file and the map is generated; you can either leave it in and use sourcemaps or edit it out and ignore the map file entirely.

Here you can find more details about the changes.

Here you can find confirmation that with the jQuery 1.11.0/2.1.0 Released the source-map comment in the minified file is removed.
