fopen() is a C library function and so you won't see any syscall instructions in your code, just a regular function call. At some point, it does call open(2), but it does that via a trampoline. There is simply a jump to the VDSO page, which is provided by the kernel to every process. The VDSO then provides code to make the system call. On modern processors, the SYSCALL or SYSENTER instructions will be used, but you can also use INT 80h on x86 processors.

ht editor can disassemble binaries in many formats. It is similar to Hiew, but open source.

To disassemble, open a binary, then press F6 and then select elf/image.

I have created a tool that combines dex2jar, jd-core and apktool: https://github.com/dirkvranckaert/AndroidDecompiler Just checkout the project locally and run the script as documented and you'll get all the resources and sources decompiled.

alias_method can be redefined if need be. (it's defined in the Module class.)

alias's behavior changes depending on its scope and can be quite unpredictable at times.

Verdict: Use alias_method - it gives you a ton more flexibility.

Usage:

def foo
  "foo"
end

alias_method :baz, :foo

The way I load static images and fonts:

module: {
    rules: [
      ....

      {
        test: /\.(jpe?g|png|gif|svg)$/i,
        /* Exclude fonts while working with images, e.g. .svg can be both image or font. */
        exclude: path.resolve(__dirname, '../src/assets/fonts'),
        use: [{
          loader: 'file-loader',
          options: {
            name: '[name].[ext]',
            outputPath: 'images/'
          }
        }]
      },
      {
        test: /\.(woff(2)?|ttf|eot|svg|otf)(\?v=\d+\.\d+\.\d+)?$/,
        /* Exclude images while working with fonts, e.g. .svg can be both image or font. */
        exclude: path.resolve(__dirname, '../src/assets/images'),
        use: [{
          loader: 'file-loader',
          options: {
            name: '[name].[ext]',
            outputPath: 'fonts/'
          },
        }
    ]
}

Don't forget to install file-loader to have that working.

By default Mysql store and return ‘date’ data type values in “YYYY/MM/DD” format. So if we want to display date in different format then we have to format date values as per our requirement in scripting language

And by the way what is the column data type and in which format you are storing the value.

Haven't used Python in several years, but I would say that it has more to do with it being a dynamically typed language than anything else. For a simple example, in Java, if I wanted to test that something wrote to standard out appropriately I could use DI and pass in any PrintStream to capture the text being written and verify it. When I'm working in Ruby, however, I can dynamically replace the 'puts' method on STDOUT to do the verify, leaving DI completely out of the picture. If the only reason I'm creating an abstraction is to test the class that's using it (think File system operations or the clock in Java) then DI/IoC creates unnecessary complexity in the solution.

May this help to someone if they have the same requirement.

This will read a file that contains the Jenkins Job name and run them iteratively from one single job.

Please change below code accordingly in your Jenkins.

   agent any

   stages {
      stage('Hello') {
         steps {
             script{
            git branch: 'Your Branch name', credentialsId: 'Your crendiatails', url: ' Your BitBucket Repo URL '

##To read file from workspace which will contain the Jenkins Job Name ###
           
     def filePath = readFile "${WORKSPACE}/ Your File Location"                   

##To read file line by line ###
 
     def lines = filePath.readLines() 
      
##To iterate and run Jenkins Jobs one by one ####

                    for (line in lines) {                                            
                      build(job: "$line/branchName",
                        parameters:
                        [string(name: 'vertical', value: "${params.vert}"),
                        string(name: 'environment', value: "${params.env}"),
                        string(name: 'branch', value: "${params.branch}"),
                        string(name: 'project', value: "${params.project}")
                        ]
                    )
                        }  
                                       }
                    
         }
         }
      }
   }

Just use ajax.abort() for example you could abort any pending ajax request before sending another one like this

//check for existing ajax request
if(ajax){ 
 ajax.abort();
 }
//then you make another ajax request
$.ajax(
 //your code here
  );

Here's what I've been doing to cope with the situation.

I use global imports on a new test class.

import static org.junit.Assert.*;
import static org.mockito.Mockito.*;
import static org.mockito.Matchers.*;

When you are finished writing your test and need to commit, you just CTRL+SHIFT+O to organize the packages. For example, you may just be left with:

import static org.mockito.Mockito.doThrow;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;
import static org.mockito.Matchers.anyString;

This allows you to code away without getting 'stuck' trying to find the correct package to import.

I too faced this issue in Hibernate 5:

@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = SEQUENCE)
@SequenceGenerator(name = SEQUENCE, sequenceName = SEQUENCE)
private Long titId;

Got a warning like this below:

Found use of deprecated [org.hibernate.id.SequenceHiLoGenerator] sequence-based id generator; use org.hibernate.id.enhanced.SequenceStyleGenerator instead. See Hibernate Domain Model Mapping Guide for details.

Then changed my code to SequenceStyleGenerator:

@Id
@GenericGenerator(name="cmrSeq", strategy = "org.hibernate.id.enhanced.SequenceStyleGenerator",
        parameters = {
                @Parameter(name = "sequence_name", value = "SEQUENCE")}
)
@GeneratedValue(generator = "sequence_name")
private Long titId;

This solved my two issues:

1. The deprecated warning is fixed
2. Now the id is generated as per the oracle sequence.

html, body {
    min-height: 100%;
}

Will do the trick.

By default, even html and body are only as big as the content they hold, but never more than the width/height of the windows. This can often lead to quite strange results.

You might also want to read http://css-tricks.com/perfect-full-page-background-image/

There are some great ways do achieve a very good and scalable full background image.

Try this:

import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import javax.swing.JFrame;
import javax.swing.JTextField;

public class Main {

    public static void main(String[] argv) throws Exception {

    JTextField textField = new JTextField();

    textField.addKeyListener(new Keychecker());

    JFrame jframe = new JFrame();

    jframe.add(textField);

    jframe.setSize(400, 350);

    jframe.setVisible(true);

}

class Keychecker extends KeyAdapter {

    @Override
    public void keyPressed(KeyEvent event) {

        char ch = event.getKeyChar();

        System.out.println(event.getKeyChar());

    }

}

Google have restricted write access to the external sdcard. From API 19 there is a framework called Storage Access Framework which allows you the set up "contracts" to allow write access.

A couple of answers already mention that moment-timezone is the way to go with named timezone. I just want to clarify something about this library that was pretty confusing to me. There is a difference between these two statements:

moment.tz(date, format, timezone)

moment(date, format).tz(timezone)

Assuming that a timezone is not specified in the date passed in:

The first code takes in the date and assumes the timezone is the one passed in. The second one will take date, assume the timezone from the browser and then change the time and timezone according to the timezone passed in.

Example:

moment.tz('2018-07-17 19:00:00', 'YYYY-MM-DD HH:mm:ss', 'UTC').format() // "2018-07-17T19:00:00Z"

moment('2018-07-17 19:00:00', 'YYYY-MM-DD HH:mm:ss').tz('UTC').format() // "2018-07-18T00:00:00Z"

My timezone is +5 from utc. So in the first case it does not change and it sets the date and time to have utc timezone.

In the second case, it assumes the date passed in is in -5, then turns it into UTC, and that's why it spits out the date "2018-07-18T00:00:00Z"

NOTE: The format parameter is really important. If omitted moment might fall back to the Date class which can unpredictable behaviors

Assuming the timezone is specified in the date passed in:

In this case they both behave equally

Even though now I understand why it works that way, I thought this was a pretty confusing feature and worth explaining.

If the command should work with both tabs and spaces as the delimiter I would use awk:

awk '{print $100,$101,$102,$103,$104,$105}' myfile > outfile

As long as you just need to specify 5 fields it is imo ok to just type them, for longer ranges you can use a for loop:

awk '{for(i=100;i<=105;i++)print $i}' myfile > outfile

If you want to use cut, you need to use the -f option:

cut -f100-105 myfile > outfile

If the field delimiter is different from TAB you need to specify it using -d:

cut -d' ' -f100-105 myfile > outfile

Check the man page for more info on the cut command.

I received the exact same error message. Except that my error message said "Could not load file or assembly 'EntityFramework, Version=6.0.0.0...", because I installed EF 6.1.1. Here's what I did to resolve the problem.

1) I started NuGet Manager Console by clicking on Tools > NuGet Package Manager > Package Manager Console 2) I uninstalled the installed EntityFramework 6.1.1 by typing the following command:

Uninstall-package EntityFramework

3) Once I received confirmation that the package has been uninstalled successfully, I installed the 5.0.0 version by typing the following command:

Install-Package EntityFramework -version 5.0.0

The problem is resolved.

Use the gcc compiler. This assumes that you have the developer tools installed.

To have a cron executed on Sunday you can use either of these:

5 8 * * 0
5 8 * * 7
5 8 * * Sun

Where 5 8 stands for the time of the day when this will happen: 8:05.

In general, if you want to execute something on Sunday, just make sure the 5th column contains either of 0, 7 or Sun. You had 6, so it was running on Saturday.

The format for cronjobs is:

 +---------------- minute (0 - 59)
 |  +------------- hour (0 - 23)
 |  |  +---------- day of month (1 - 31)
 |  |  |  +------- month (1 - 12)
 |  |  |  |  +---- day of week (0 - 6) (Sunday=0 or 7)
 |  |  |  |  |
 *  *  *  *  *  command to be executed

You can always use crontab.guru as a editor to check your cron expressions.

The window['variableName'] method ONLY works if the variable is defined in the global scope. The correct answer is "Refactor". If you can provide an "Object" context then a possible general solution exists, but there are some variables which no global function could resolve based on the scope of the variable.

(function(){
    var findMe = 'no way';
})();

Try this code, it works perfectly.

var IDLE_TIMEOUT = 10; //seconds
var _idleSecondsCounter = 0;

document.onclick = function () {
    _idleSecondsCounter = 0;
};

document.onmousemove = function () {
    _idleSecondsCounter = 0;
};

document.onkeypress = function () {
    _idleSecondsCounter = 0;
};

window.setInterval(CheckIdleTime, 1000);

function CheckIdleTime() {
    _idleSecondsCounter++;
    var oPanel = document.getElementById("SecondsUntilExpire");
    if (oPanel)
        oPanel.innerHTML = (IDLE_TIMEOUT - _idleSecondsCounter) + "";
    if (_idleSecondsCounter >= IDLE_TIMEOUT) {
        alert("Time expired!");
        document.location.href = "SessionExpired.aspx";
    }
}

You're running the code before the DOM is loaded.

Try this:

Live example:

http://jsfiddle.net/FvMYz/

$(function() {    // Makes sure the code contained doesn't run until
                  //     all the DOM elements have loaded

    $('#colorselector').change(function(){
        $('.colors').hide();
        $('#' + $(this).val()).show();
    });

});

To create a new object you can either use placement new, as mentioned above, or have your class implement a clone() method that creates a copy of the object. You can then call this clone method using a member function pointer as explained above to create new instances of the object. The advantage of clone is that sometimes you may be working with a pointer to a base class where you don't know the type of the object. In this case a clone() method can be easier to use. Also, clone() will let you copy the state of the object if that is what you want.

var keyCode = evt.keyCode;
if (keyCode==8)
alert('you pressed backspace');

if(keyCode==116)
alert('you pressed f5 to reload page')

(N-1) + (N-2) +...+ 2 + 1 is a sum of N-1 items. Now reorder the items so, that after the first comes the last, then the second, then the second to last, i.e. (N-1) + 1 + (N-2) + 2 +... The way the items are ordered now you can see that each of those pairs is equal to N (N-1+1 is N, N-2+2 is N). Since there are N-1 items, there are (N-1)/2 such pairs. So you're adding N (N-1)/2 times, so the total value is N*(N-1)/2.

Yes, this is confusing...

According to this blog post, it looks like this is an omission from WPF.

To make it work you need to use a style:

    <Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
        <Border.Style>
            <Style>
                <Setter Property="Border.Background" Value="Blue"/>
                <Style.Triggers>
                    <Trigger Property="Border.IsMouseOver" Value="True">
                        <Setter Property="Border.Background" Value="Green" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </Border.Style>
        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
    </Border>

I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.

What the code does, is that the number 8000 is counting up from 0 to 8000. The problem is, that it is placed at the middle of quite long page, and once user scroll down and actually see the number, the animation is already dine. I would like to trigger the counter, once it appears in the viewport.

JS:

$('.count').each(function () {
                $(this).prop('Counter',0).animate({
                        Counter: $(this).text()
                }, {
                        duration: 4000,
                        easing: 'swing',
                        step: function (now) {
                                $(this).text(Math.ceil(now));
                        }
                });
            });

And HTML:

 <span class="count">8000</span>

Apparently, all we need to do is:

1. Set all constraints to Scroll View (i.e. fix scroll view first)

2. Then set distance-from-scrollView constraint to the bottom most item to scroll view (which is the super view).

Note: Step 2 will tell storyboard where the last piece of content lies within Scroll view.

Only checked and checked="checked" are valid. Your other options depend on error recovery in browsers.

checked="yes" and checked="true" are particularly bad as they imply that checked="no" and checked="false" will set the default state to be unchecked … which they will not.

That URL will points to your own server-side file upload action. The documentation doesn't go into much detail, but fortunately Don Jones fills in some of the blanks here:

How can you integrate a custom file browser/uploader with CKEditor?

See also:

http://zerokspot.com/weblog/2009/09/09/custom-filebrowser-callbacks-ckeditor/

Since I needed this as well, I'll go into more detail on how to do this.

Note: I assume you used the standard template form for generating your UIPageViewController structure - which has both the modelViewController and dataViewController created when you invoke it. If you don't understand what I wrote - go back and create a new project that uses the UIPageViewController as it's basis. You'll understand then.

So, needing to flip to a particular page involves setting up the various pieces of the method listed above. For this exercise, I'm assuming that it's a landscape view with two views showing. Also, I implemented this as an IBAction so that it could be done from a button press or what not - it's just as easy to make it selector call and pass in the items needed.

So, for this example you need the two view controllers that will be displayed - and optionally, whether you're going forward in the book or backwards.

Note that I merely hard-coded where to go to pages 4 & 5 and use a forward slip. From here you can see that all you need to do is pass in the variables that will help you get these items...

-(IBAction) flipToPage:(id)sender {

    // Grab the viewControllers at position 4 & 5 - note, your model is responsible for providing these.  
    // Technically, you could have them pre-made and passed in as an array containing the two items...

    DataViewController *firstViewController = [self.modelController viewControllerAtIndex:4 storyboard:self.storyboard];
    DataViewController *secondViewController = [self.modelController viewControllerAtIndex:5 storyboard:self.storyboard];

    //  Set up the array that holds these guys...

    NSArray *viewControllers = nil;

    viewControllers = [NSArray arrayWithObjects:firstViewController, secondViewController, nil];

    //  Now, tell the pageViewContoller to accept these guys and do the forward turn of the page.
    //  Again, forward is subjective - you could go backward.  Animation is optional but it's 
    //  a nice effect for your audience.

      [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];

    //  Voila' - c'est fin!  

}

You need to open the file in binary b mode to take care of blank lines in Python 2. This isn't required in Python 3.

So, change open('test.csv', 'w') to open('test.csv', 'wb').

I had the same problem here... I tried to use destroy() and clear() method, but without success.

I resolved it the next way:

HTML:

<div id="pieChartContent">
    <canvas id="pieChart" width="300" height="300"></canvas>
</div>

Javascript:

var pieChartContent = document.getElementById('pieChartContent');
pieChartContent.innerHTML = ' ';
$('#pieChartContent').append('<canvas id="pieChart" width="300" height="300"><canvas>');

ctx = $("#pieChart").get(0).getContext("2d");        
var myPieChart = new Chart(ctx).Pie(data, options);

It works perfect to me... I hope that It helps.

You need to roll your own method to eliminate the files you don't want.

This isn't easy with the built in tools, but you could use RegExKit Lite to assist with finding the elements in the returned array you are interested in. According to the release notes this should work in both Cocoa and Cocoa-Touch applications.

Here's the demo code I wrote up in about 10 minutes. I changed the < and > to " because they weren't showing up inside the pre block, but it still works with the quotes. Maybe somebody who knows more about formatting code here on StackOverflow will correct this (Chris?).

This is a "Foundation Tool" Command Line Utility template project. If I get my git daemon up and running on my home server I'll edit this post to add the URL for the project.

#import "Foundation/Foundation.h"
#import "RegexKit/RegexKit.h"

@interface MTFileMatcher : NSObject 
{
}
- (void)getFilesMatchingRegEx:(NSString*)inRegex forPath:(NSString*)inPath;
@end

int main (int argc, const char * argv[])
{
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

    // insert code here...
    MTFileMatcher* matcher = [[[MTFileMatcher alloc] init] autorelease];
    [matcher getFilesMatchingRegEx:@"^.+\\.[Jj][Pp][Ee]?[Gg]$" forPath:[@"~/Pictures" stringByExpandingTildeInPath]];

    [pool drain];
    return 0;
}

@implementation MTFileMatcher
- (void)getFilesMatchingRegEx:(NSString*)inRegex forPath:(NSString*)inPath;
{
    NSArray* filesAtPath = [[[NSFileManager defaultManager] directoryContentsAtPath:inPath] arrayByMatchingObjectsWithRegex:inRegex];
    NSEnumerator* itr = [filesAtPath objectEnumerator];
    NSString* obj;
    while (obj = [itr nextObject])
    {
        NSLog(obj);
    }
}
@end

This approach works for me in Node.js, Is there any problem with this one?

try Parsing and Formatting

Take an example Parsing

String input = ...;
try {
    DateTimeFormatter formatter =
                      DateTimeFormatter.ofPattern("MMM d yyyy");
    LocalDate date = LocalDate.parse(input, formatter);
    System.out.printf("%s%n", date);
}
catch (DateTimeParseException exc) {
    System.out.printf("%s is not parsable!%n", input);
    throw exc;      // Rethrow the exception.
}

Formatting

ZoneId leavingZone = ...;
ZonedDateTime departure = ...;

try {
    DateTimeFormatter format = DateTimeFormatter.ofPattern("MMM d yyyy  hh:mm a");
    String out = departure.format(format);
    System.out.printf("LEAVING:  %s (%s)%n", out, leavingZone);
}
catch (DateTimeException exc) {
    System.out.printf("%s can't be formatted!%n", departure);
    throw exc;
}

The output for this example, which prints both the arrival and departure time, is as follows:

LEAVING:  Jul 20 2013  07:30 PM (America/Los_Angeles)
ARRIVING: Jul 21 2013  10:20 PM (Asia/Tokyo)

Please note there's also git reset --soft HEAD^. It's similar to git reset (which defaults to --mixed) but it retains the index contents. So that if you've added/removed files, you have them in the index already.

Turns out to be very useful in case of giant commits.

The Facebook "Graph API Rate Limiting" docs says that an error with code #4 is an app level rate limit, which is different than user level rate limits. Although it doesn't give any exact numbers, it describes their app level rate-limit as:

This rate limiting is applied globally at the app level. Ads api calls are excluded.

• Rate limiting happens real time on sliding window for past one hour.
• Stats is collected for number of calls and queries made, cpu time spent, memory used for each app.
• There is a limit for each resource multiplied by monthly active users of a given app.
• When the app uses more than its allowed resources the error is thrown.
• Error, Code: 4, Message: Application request limit reached

The docs also give recommendations for avoiding the rate limits. For app level limits, they are:

Recommendations:

• Verify the error code (4) to confirm the throttling type.
• Do not make burst of calls, spread out the calls throughout the day.
• Do smart fetching of data (important data, non duplicated data, etc).
  • Real-time insights, make sure API calls are structured in a way that you can read insights for as many as Page posts as possible, with minimum number of requests.
  • Don't fetch users feed twice (in the case that two App users have a specific friend in common)
  • Don't fetch all user's friends feed in a row if the number of friends is more than 250. Separate the fetches over different days. As an option, fetch first the app user's news feed (me/home) in order to detect which friends are more important to the App user. Then, fetch those friends feeds first.
• Consider to limit/filter the requests by using the following parameters: "since", "until", "limit"
• For page related calls use realtime updates to subscribe to changes in data.
• Field expansion allows ton "join" multiple graph queries into a single call.
• Etags to check if the data querying has changed since the last check.
• For page management developers who does not have massive user base, have the admins of the page to accept the app to increase the number of users.

Finally, the docs give the following informational tips:

• Batching calls will not reduce the number of api calls.
• Making parallel calls will not reduce the number of api calls.

Just to add to the conversation, I have found a more elegant way to change the color of the box plot by iterating over the dictionary of the object itself

import numpy as np
import matplotlib.pyplot as plt

def color_box(bp, color):

    # Define the elements to color. You can also add medians, fliers and means
    elements = ['boxes','caps','whiskers']

    # Iterate over each of the elements changing the color
    for elem in elements:
        [plt.setp(bp[elem][idx], color=color) for idx in xrange(len(bp[elem]))]
    return

a = np.random.uniform(0,10,[100,5])    

bp = plt.boxplot(a)
color_box(bp, 'red')

Cheers!

I don't think you can tell with the std::string class. However, if you really need this information, you could always derive a class from std::string and give the derived class the ability to tell if it had been changed since construction (or some other arbitrary time). Or better yet, just write a new class that wraps std::string since deriving from std::string may not be a good idea given the lack of a base class virtual destructor. That's probably more work, but more work tends to be needed for an optimal solution.

Of course, you can always just assume if it contains something other than "" then it has been "set", this won't detect it manually getting set to "" though.

$('.launchConfirm').on('click', function (e) {
    $('#confirm')
        .modal({ backdrop: 'static', keyboard: false })
        .one('click', '#delete', function (e) {
            //delete function
        });
});

FIDDLE

For your button:

<button class='btn btn-danger btn-xs launchConfirm' type="button" name="remove_levels"><span class="fa fa-times"></span> delete</button></td>

I used almost all of the answers posted here but not comfortable with that so i dig one step furter and found easy solution that fits my need and feel worth sharing with you guys.
Instead of iteration all over the options or using JQuery you can do using core JS in simple steps:

Example

<select id="org_list">
  <option value="23">IBM</option>
  <option value="33">DELL</option>
  <option value="25">SONY</option>
  <option value="29">HP</option>
</select>

So you must know the value of the option to select.

function selectOrganization(id){
    org_list=document.getElementById('org_list');
    org_list.selectedIndex=org_list.querySelector('option[value="'+id+'"]').index;
}

How to Use?

selectOrganization(25); //this will select SONY from option List

When I found that there was no process using port 80 by using commands

netstat -abno | find ":80"

there was not a problem of any process using port 80.

Then I ran command (in cmd)

C:\xampp\apache\bin\httpd.exe

it showed some error in the virtual hosts configuration in httpd-vhosts.conf file which was recently edited by me for installation in a WordPress PHP environment in the Eclipse IDE. So I deleted those lines and Apache started perfectly.

You could also invoke the new command feature of Terminal by pressing the Shift + ? + N key combination. The command you put into the box will be run in a new Terminal window.

You can use int casting which allows the base specification.

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

You can use eclipse to generate a runnable Jar : Export/Runable Jar file

You can use display: table-cell in order to render the div as a table cell and then use vertical-align like you would do in a normal table cell.

#AlertDiv {
    display: table-cell;
    vertical-align: middle;
    text-align: center;
}

You can try it here: http://jsfiddle.net/KaXY5/424/

It's not really a cheat-sheet, but for me I setup a 'java' search keyword in Google Chrome to search over the javadoc, using site:<javadoc_domain_here>.

You could do the same but also add the domain for the Sun Java Tutorial and for several Java FAQ sites and you'd be OK.

Otherwise, StackOverflow is a pretty good cheat-sheet :)

Try a case statement

WHERE
CASE WHEN @zipCode IS NULL THEN 1
ELSE @zipCode
END

If you'd like to do this in ggplot, an API change was made to geom_histogram() that leads to an error: https://github.com/hadley/ggplot2/issues/1465

To get around this, use geom_bar():

animals <- c("cat", "dog",  "dog", "dog", "dog", "dog", "dog", "dog", "cat", "cat", "bird")

library(ggplot2)
# counts
ggplot(data.frame(animals), aes(x=animals)) +
  geom_bar()

Try this, create drawable in your resource...

<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="@color/white"/>
    <size android:height="20dp"
        android:width="20dp"/>
</shape>

then use...

 Drawable mDrawable = getActivity().getResources().getDrawable(R.drawable.bg_rectangle_multicolor);
mDrawable.setColorFilter(Color.parseColor(color), PorterDuff.Mode.SRC_IN);
mView1.setBackground(mDrawable);

with color... "#FFFFFF"

if the color is transparent use... setAlpha

mView1.setAlpha(x); with x float 0-1 Ej (0.9f)

Good Luck

You can close a figure by calling matplotlib.pyplot.close, for example:

from numpy import *
import matplotlib.pyplot as plt
from scipy import *

t = linspace(0, 0.1,1000)
w = 60*2*pi


fig = plt.figure()
plt.plot(t,cos(w*t))
plt.plot(t,cos(w*t-2*pi/3))
plt.plot(t,cos(w*t-4*pi/3))
plt.show()
plt.close(fig)

You can also close all open figures by calling matplotlib.pyplot.close("all")

Use the command dir to list all the directories and files in a directory; ls is a unix command.

Just as alternative you may consider using execs... (I wouldn't recommend it though)

exec { 'this will output stuff':
  path      => '/bin',
  command   => 'echo Hello World!',
  logoutput => true,
}

So when you run puppet you should find some output like so:

notice: /Stage[main]//Exec[this will output stuff]/returns: Hello World!
notice: /Stage[main]//Exec[this will output stuff]/returns: executed successfully
notice: Finished catalog run in 0.08 seconds

The first line being logged output.

Works for me too, here is a better solution::

fiddle demo

<form id="myForm">
  <input type="radio" name="radioName" value="1" />one<br />
  <input type="radio" name="radioName" value="2" />two 
</form>

<script>
$('#myForm input[type=radio]').change(function() {       
    alert(this.value);
});
</script>

You must make sure that you initialized jquery above all other imports and javascript functions. Because $ is a jquery function. Even

$(function(){
 <code>
}); 

will not check jquery initialised or not. It will ensure that <code> will run only after all the javascripts are initialized.

$cart = array();
$cart[] = 11;
$cart[] = 15;

// etc

//Above is correct. but below one is for further understanding

$cart = array();
for($i = 0; $i <= 5; $i++){
          $cart[] = $i;  

//if you write $cart = [$i]; you will only take last $i value as first element in array.

}
echo "<pre>";
print_r($cart);
echo "</pre>";

As noted in the answer provided by Tim Cooper, java.awt.Desktop has provided this capability since Java version 6 (1.6), but with the following caveat:

Use the isDesktopSupported() method to determine whether the Desktop API is available. On the Solaris Operating System and the Linux platform, this API is dependent on Gnome libraries. If those libraries are unavailable, this method will return false.

For platforms which do not support or provide java.awt.Desktop, look into the BrowserLauncher2 project. It is derived and somewhat updated from the BrowserLauncher class originally written and released by Eric Albert. I used the original BrowserLauncher class successfully in a multi-platform Java application which ran locally with a web browser interface in the early 2000s.

Note that BrowserLauncher2 is licensed under the GNU Lesser General Public License. If that license is unacceptable, look for a copy of the original BrowserLauncher which has a very liberal license:

In programming terms, it's the larger surrounding part which can have any influence on the behaviour of the current unit of work. E.g. the running environment used, the environment variables, instance variables, local variables, state of other classes, state of the current environment, etcetera.

In some API's you see this name back in an interface/class, e.g. Servlet's ServletContext, JSF's FacesContext, Spring's ApplicationContext, Android's Context, JNDI's InitialContext, etc. They all often follow the Facade Pattern which abstracts the environmental details the enduser doesn't need to know about away in a single interface/class.

In my case when I use something like result.class.name I got something like Module1::class_name. But if we only want class_name, use

result.class.table_name.singularize

I just experienced this with the line:

$('<div id="editor" />').dialogelfinder({

I got the error "dialogelfinder is not a function" because another component was inserting a call to load an older version of JQuery (1.7.2) after the newer version was loaded.

As soon as I commented out the second load, the error went away.

What you call "Two-Way SSL" is usually called TLS/SSL with client certificate authentication.

In a "normal" TLS connection to example.com only the client verifies that it is indeed communicating with the server for example.com. The server doesn't know who the client is. If the server wants to authenticate the client the usual thing is to use passwords, so a client needs to send a user name and password to the server, but this happens inside the TLS connection as part of an inner protocol (e.g. HTTP) it's not part of the TLS protocol itself. The disadvantage is that you need a separate password for every site because you send the password to the server. So if you use the same password on for example PayPal and MyPonyForum then every time you log into MyPonyForum you send this password to the server of MyPonyForum so the operator of this server could intercept it and try it on PayPal and can issue payments in your name.

Client certificate authentication offers another way to authenticate the client in a TLS connection. In contrast to password login, client certificate authentication is specified as part of the TLS protocol. It works analogous to the way the client authenticates the server: The client generates a public private key pair and submits the public key to a trusted CA for signing. The CA returns a client certificate that can be used to authenticate the client. The client can now use the same certificate to authenticate to different servers (i.e. you could use the same certificate for PayPal and MyPonyForum without risking that it can be abused). The way it works is that after the server has sent its certificate it asks the client to provide a certificate too. Then some public key magic happens (if you want to know the details read RFC 5246) and now the client knows it communicates with the right server, the server knows it communicates with the right client and both have some common key material to encrypt and verify the connection.

Why use an external lib, when google play services (since version 7.8.0) includes a barcode decoder.

You should do something like that:

<LinearLayout
    android:id="@+id/widget34"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:layout_below="@+id/tv_scanning_for"
    android:layout_centerHorizontal="true">

    <ListView
        android:id="@+id/lv_events"
        android:textSize="18sp"         
        android:cacheColorHint="#00000000"
        android:layout_height="1"
        android:layout_width="fill_parent"
        android:layout_weight="0dp"
        android:layout_below="@+id/tv_scanning_for"
        android:layout_centerHorizontal="true"
        />

</LinearLayout>

Also use dp instead px or read about it here.

I wrote an alternative solution how to make any element focusable and "blurable".

It's based on making an element as contentEditable and hiding visually it and disabling edit mode itself:

el.addEventListener("keydown", function(e) {
  e.preventDefault();
  e.stopPropagation();
});

el.addEventListener("blur", cbBlur);
el.contentEditable = true;

DEMO

Note: Tested in Chrome, Firefox, and Safari (OS X). Not sure about IE.

Related: I was searching for a solution for VueJs, so for those who interested/curious how to implement such functionality using Vue Focusable directive, please take a look.

More correct create DTO for API queries, for example entityDTO:

1. Default response OK with list of entities:

@GetMapping(produces=MediaType.APPLICATION_JSON_VALUE)
@ResponseStatus(HttpStatus.OK)
public List<EntityDto> getAll() {
    return entityService.getAllEntities();
}

But if you need return different Map parameters you can use next two examples
2. For return one parameter like map:

@GetMapping(produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> getOneParameterMap() {
    return ResponseEntity.status(HttpStatus.CREATED).body(
            Collections.singletonMap("key", "value"));
}

3. And if you need return map of some parameters(since Java 9):

@GetMapping(produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Object> getSomeParameters() {
    return ResponseEntity.status(HttpStatus.OK).body(Map.of(
            "key-1", "value-1",
            "key-2", "value-2",
            "key-3", "value-3"));
}

For a select like this

<select class="btn btn-info pull-right" id="list-name" style="width: auto;">
   <option id="0">CHOOSE AN OPTION</option>
   <option id="127">John Doe</option>
   <option id="129" selected>Jane Doe</option>

... you can get the id this way:

$('#list-name option:selected').attr('id');

Or you can use value instead, and get it the easy way...

<select class="btn btn-info pull-right" id="list-name" style="width: auto;">
   <option value="0">CHOOSE AN OPTION</option>
   <option value="127">John Doe</option>
   <option value="129" selected>Jane Doe</option>

like this:

$('#list-name').val();

You can use except! from the facets gem:

>> require 'facets' # or require 'facets/hash/except'
=> true
>> {:a => 1, :b => 2}.except(:a)
=> {:b=>2}

The original hash does not change.

EDIT: as Russel says, facets has some hidden issues and is not completely API-compatible with ActiveSupport. On the other side ActiveSupport is not as complete as facets. In the end, I'd use AS and let the edge cases in your code.

SVG scaling and PNG rendering

Using pycairo and librsvg I was able to achieve SVG scaling and rendering to a bitmap. Assuming your SVG is not exactly 256x256 pixels, the desired output, you can read in the SVG to a Cairo context using rsvg and then scale it and write to a PNG.

main.py

import cairo
import rsvg

width = 256
height = 256

svg = rsvg.Handle('cool.svg')
unscaled_width = svg.props.width
unscaled_height = svg.props.height

svg_surface = cairo.SVGSurface(None, width, height)
svg_context = cairo.Context(svg_surface)
svg_context.save()
svg_context.scale(width/unscaled_width, height/unscaled_height)
svg.render_cairo(svg_context)
svg_context.restore()

svg_surface.write_to_png('cool.png')

RSVG C binding

From the Cario website with some minor modification. Also a good example of how to call a C-library from Python

from ctypes import CDLL, POINTER, Structure, byref, util
from ctypes import c_bool, c_byte, c_void_p, c_int, c_double, c_uint32, c_char_p


class _PycairoContext(Structure):
    _fields_ = [("PyObject_HEAD", c_byte * object.__basicsize__),
                ("ctx", c_void_p),
                ("base", c_void_p)]


class _RsvgProps(Structure):
    _fields_ = [("width", c_int), ("height", c_int),
                ("em", c_double), ("ex", c_double)]


class _GError(Structure):
    _fields_ = [("domain", c_uint32), ("code", c_int), ("message", c_char_p)]


def _load_rsvg(rsvg_lib_path=None, gobject_lib_path=None):
    if rsvg_lib_path is None:
        rsvg_lib_path = util.find_library('rsvg-2')
    if gobject_lib_path is None:
        gobject_lib_path = util.find_library('gobject-2.0')
    l = CDLL(rsvg_lib_path)
    g = CDLL(gobject_lib_path)
    g.g_type_init()

    l.rsvg_handle_new_from_file.argtypes = [c_char_p, POINTER(POINTER(_GError))]
    l.rsvg_handle_new_from_file.restype = c_void_p
    l.rsvg_handle_render_cairo.argtypes = [c_void_p, c_void_p]
    l.rsvg_handle_render_cairo.restype = c_bool
    l.rsvg_handle_get_dimensions.argtypes = [c_void_p, POINTER(_RsvgProps)]

    return l


_librsvg = _load_rsvg()


class Handle(object):
    def __init__(self, path):
        lib = _librsvg
        err = POINTER(_GError)()
        self.handle = lib.rsvg_handle_new_from_file(path.encode(), byref(err))
        if self.handle is None:
            gerr = err.contents
            raise Exception(gerr.message)
        self.props = _RsvgProps()
        lib.rsvg_handle_get_dimensions(self.handle, byref(self.props))

    def get_dimension_data(self):
        svgDim = self.RsvgDimensionData()
        _librsvg.rsvg_handle_get_dimensions(self.handle, byref(svgDim))
        return (svgDim.width, svgDim.height)

    def render_cairo(self, ctx):
        """Returns True is drawing succeeded."""
        z = _PycairoContext.from_address(id(ctx))
        return _librsvg.rsvg_handle_render_cairo(self.handle, z.ctx)

Piggybacking on what the other answers say, since you don't know how to do them at all, here's an example of how you might do it in JavaScript:

var charactersOnly = "This contains only characters";
var nonCharacters = "This has _@#*($()*@#$(*@%^_(#@!$ non-characters";

if (charactersOnly.search(/[^a-zA-Z]+/) === -1) {
  alert("Only characters");
}

if (nonCharacters.search(/[^a-zA-Z]+/)) {
  alert("There are non characters.");
}

The / starting and ending the regular expression signify that it's a regular expression. The search function takes both strings and regexes, so the / are necessary to specify a regex.

From the MDN Docs, the function returns -1 if there is no match.

Also note: that this works for only a-z, A-Z. If there are spaces, it will fail.

Following @Sampson's answer, I approached it this way -

HTML:

1. I have a div with content class in each page, which holds the contents of that page. Header and Footer are separated.
2. I have added a unique class for each page with content. For example, if I am creating a CONTACT US page, I will put the contents of the page inside <section class="content contact-us"></section>.
3. By this, it makes it easier for me to write page specific CSS in a single style.css.

<body>
    <header>
        <div class="nav-menu">
            <ul class="parent-nav">
                <li><a href="#">Home</a></li>
                <li><a href="#">Contact us</a></li>
                ...
            </ul>
        </div>
    </header>

    <section class="content contact-us">
        Content for contact us page goes here
    </section>

    <footer> ... </footer>

</body>

CSS:

1. I have defined a single active class, which holds the styling for an active menu.

.active {
    color: red;
    text-decoration: none;
}

<body>
    <header>
        <div class="nav-menu">
            <ul class="parent-nav">
                <li><a href="#">Home</a></li>
                <li><a href="#">Contact us</a></li>
                ...
            </ul>
        </div>
    </header>

    <section class="content contact-us">
        Content for contact us page goes here
    </section>

    <footer> ... </footer>

</body>

JavaScript:

1. Now in JavaScript, I aim to compare the menu link text with the unique class name defined in HTML. I am using jQuery.
2. First I have taken all the menu texts, and performed some string functions to make the texts lowercase and replace spaces with hyphens so it matches the class name.
3. Now, if the content class have the same class as menu text (lowercase and without spaces), add active class to the menu item.

var $allMenu = $('.nav-menu > .parent-nav > li > a');
var $currentContent = $('.content');
$allMenu.each(function() {
  $singleMenuTitle = $(this).text().replace(/\s+/g, '-').toLowerCase();
  if ($currentContent.hasClass($singleMenuTitle)) {
    $(this).addClass('active');
  }
});

.active {
  color: red;
  text-decoration: none;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<body>
  <header>
    <div class="nav-menu">
      <ul class="parent-nav">
        <li><a href="#">Home</a></li>
        <li><a href="#">Contact us</a></li>
        ...
      </ul>
    </div>
  </header>

  <section class="content contact-us">
    Content for contact us page goes here
  </section>

  <footer> ... </footer>

</body>

Why I Approached This?

1. @Sampson's answer worked very well for me, but I noticed that I had to add new code every time I want to add new page.
2. Also in my project, the body tag is in header.php file which means I cannot write unique class name for every page.

No, there isn't. The border will always be as tall as the element.

You can achieve the same effect by wrapping the contents of the cell in a <span>, and applying height/border styles to that. Or by drawing a short vertical line in an 1 pixel wide PNG which is the correct height, and applying it as a background to the cell:

background:url(line.png) bottom right no-repeat;

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

I tried lots of different solutions, the only one that worked for me was based on the solution by Chris G on this page (but with a slight modification).

I have turned it into a jQuery plugin for future use for anyone that needs it

(function($){
    $.fn.setCursorToTextEnd = function() {
        var $initialVal = this.val();
        this.val($initialVal);
    };
})(jQuery);

example of usage:

$('#myTextbox').setCursorToTextEnd();

By illustration:

pip --version
  pip 19.0.3 from /usr/lib/python3.7/site-packages/pip (python 3.7)

pip3 --version
  pip 19.0.3 from /usr/lib/python3.7/site-packages/pip (python 3.7)

python --version
  Python 3.7.3

which python
  /usr/bin/python

ls -l '/usr/bin/python'
  lrwxrwxrwx 1 root root 7 Mar 26 14:43 /usr/bin/python -> python3

which python3
  /usr/bin/python3

ls -l /usr/bin/python3
  lrwxrwxrwx 1 root root 9 Mar 26 14:43 /usr/bin/python3 -> python3.7

ls -l /usr/bin/python3.7
  -rwxr-xr-x 2 root root 14120 Mar 26 14:43 /usr/bin/python3.7

Thus, my in my default system python (Python 3.7.3), pip is pip3.

You're looking for the /Y switch.

According to the Android Studio download page, the SDK comes bundled with Android Studio. It has its own copy when you install Android Studio.

ADT is a plugin for Eclipse. Try reading through that webpage to see if there is something that got missed when installing.

Here is the wording from the site, regarding ADT:

Similar to Eclipse with the ADT Plugin, Android Studio provides integrated Android developer tools for development and debugging.

The way I see it, the only place for a nested query would be in the WHERE clause, so e.g.

SELECT country.name, country.headofstate
FROM country 
WHERE country.headofstate LIKE 'A%' AND 
country.id in (SELECT country_id FROM city WHERE population > 100000)

Apart from that, I have to agree with Adrian on: why the heck should you use nested queries?

in other way, you can do it with javascript , in Jquery you can use something like:

$('div:visible').last()

"argument is of length zero" is a very specific problem that comes from one of my least-liked elements of R. Let me demonstrate the problem:

> FALSE == "turnip"
[1] FALSE
> TRUE == "turnip"
[1] FALSE
> NA == "turnip"
[1] NA
> NULL == "turnip"
logical(0)

As you can see, comparisons to a NULL not only don't produce a boolean value, they don't produce a value at all - and control flows tend to expect that a check will produce some kind of output. When they produce a zero-length output... "argument is of length zero".

(I have a very long rant about why this infuriates me so much. It can wait.)

So, my question; what's the output of sum(is.null(data[[k]]))? If it's not 0, you have NULL values embedded in your dataset and will need to either remove the relevant rows, or change the check to

if(!is.null(data[[k]][[k2]]) & temp > data[[k]][[k2]]){
    #do stuff
}

Hopefully that helps; it's hard to tell without the entire dataset. If it doesn't help, and the problem is not a NULL value getting in somewhere, I'm afraid I have no idea.

On Kotlin you can set width and height of any view directly using their virtual properties:

someView.layoutParams.width = 100
someView.layoutParams.height = 200

Using the sapply

 patterns <- c("A1", "A9", "A6")
         df <- data.frame(name=c("A","Ale","Al","lex","x"),Letters=c("A1","A2","A9","A1","A9"))



   name Letters
1    A      A1
2  Ale      A2
3   Al      A9
4  lex      A1
5    x      A9


 df[unlist(sapply(patterns, grep, df$Letters, USE.NAMES = F)), ]
  name Letters
1    A      A1
4  lex      A1
3   Al      A9
5    x      A9

Here's an example of how you would accomplish such a task:

#import <Foundation/Foundation.h>
typedef int (^IntBlock)();

@interface myobj : NSObject
{
    IntBlock compare;
}

@property(readwrite, copy) IntBlock compare;

@end

@implementation myobj

@synthesize compare;

- (void)dealloc 
{
   // need to release the block since the property was declared copy. (for heap
   // allocated blocks this prevents a potential leak, for compiler-optimized 
   // stack blocks it is a no-op)
   // Note that for ARC, this is unnecessary, as with all properties, the memory management is handled for you.
   [compare release];
   [super dealloc];
}
@end

int main () {
    @autoreleasepool {
        myobj *ob = [[myobj alloc] init];
        ob.compare = ^
        {
            return rand();
        };
        NSLog(@"%i", ob.compare());
        // if not ARC
        [ob release];
    }

    return 0;
}

Now, the only thing that would need to change if you needed to change the type of compare would be the typedef int (^IntBlock)(). If you need to pass two objects to it, change it to this: typedef int (^IntBlock)(id, id), and change your block to:

^ (id obj1, id obj2)
{
    return rand();
};

I hope this helps.

EDIT March 12, 2012:

For ARC, there are no specific changes required, as ARC will manage the blocks for you as long as they are defined as copy. You do not need to set the property to nil in your destructor, either.

Try this code. It works for me:

unzip(zipfile="<directory and filename>",
      exdir="<directory where the content will be extracted>")

Example:

unzip(zipfile="./data/Data.zip",exdir="./data")

Here is an example using jQuery...

 <head>
   <title>Test</title>
   <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
   <script type="text/javascript" src="http://www.json.org/json2.js"></script>
   <script type="text/javascript">
     $(function() {
       var frm = $(document.myform);
       var dat = JSON.stringify(frm.serializeArray());

       alert("I am about to POST this:\n\n" + dat);

       $.post(
         frm.attr("action"),
         dat,
         function(data) {
           alert("Response: " + data);
         }
       );
     });
   </script>
</head>

The jQuery serializeArray function creates a Javascript object with the form values. Then you can use JSON.stringify to convert that into a string, if needed. And you can remove your body onload, too.

Here is a simple example :

Create or alter PROCEDURE getPersonCountByLastName (
@lastName varchar(20),
@count int OUTPUT
)
As
Begin
select @count = count(personSid) from Person where lastName like @lastName
End;

Execute below statements in one batch (by selecting all)

1. Declare @count int
2. Exec getPersonCountByLastName kumar, @count output
3. Select @count

When i tried to execute statements 1,2,3 individually, I had the same error. But when executed them all at one time, it worked fine.

The reason is that SQL executes declare, exec statements in different sessions.

Open to further corrections.

Owl Carousel version matters a lot, as of now (2nd Aug 2020) the version is 2.3.4 and the right options for autoplay are:

$(".owl-carousel").owlCarousel({
    autoplay : true,
    autoplayTimeout: 3000,//Autoplay interval timeout.
    loop:true,//Infinity loop. Duplicate last and first items to get loop illusion.
    items:1 //The number of items you want to see on the screen.
});

Try a regex with re.sub. You can search for all whitespace and replace with an empty string.

\s in your pattern will match whitespace characters - and not just a space (tabs, newlines, etc). You can read more about it in the manual.

rsubmit;
options missing=0;
ods listing close;
ods csv file='\\FILE_PATH_and_Name_of_report.csv';

proc sql;
SELECT *
FROM `YOUR_FINAL_TABLE_NAME';
quit;
ods csv close;

endrsubmit;

Try this to redirect cout to file.

#include <iostream>
#include <fstream>

int main()
{
    /** backup cout buffer and redirect to out.txt **/
    std::ofstream out("out.txt");

    auto *coutbuf = std::cout.rdbuf();
    std::cout.rdbuf(out.rdbuf());

    std::cout << "This will be redirected to file out.txt" << std::endl;

    /** reset cout buffer **/
    std::cout.rdbuf(coutbuf);

    std::cout << "This will be printed on console" << std::endl;

    return 0;
}

Not sure how it compares for performance, but this works.

var today = new Date();
var day = today.getDay() || 7; // Get current day number, converting Sun. to 7
if( day !== 1 )                // Only manipulate the date if it isn't Mon.
    today.setHours(-24 * (day - 1));   // Set the hours to day number minus 1
                                         //   multiplied by negative 24
alert(today); // will be Monday

Or as a function:

# modifies _date_
function setToMonday( date ) {
    var day = date.getDay() || 7;  
    if( day !== 1 ) 
        date.setHours(-24 * (day - 1)); 
    return date;
}

setToMonday(new Date());

You need to use <> operator:

while (<>) {
    print $_; # or simply "print;"
}

Which can be compacted to:

print while (<>);

Arbitrary file:

open F, "<file.txt" or die $!;
while (<F>) {
    print $_;
}
close F;

I, too, have this problem on an older Mac that I upgraded to Lion.

Before reading the terminfo tip, I was able to get vi and less working by doing "export TERM=xterm".

After reading the tip, I grabbed /usr/share/terminfo from a newer Mac that has fresh install of Lion and does not exhibit this problem.

Now, even though echo $TERM still yields xterm-256color, vi and less now work fine.

I've a same problem. After move machine from restore of Time Machine, on another host. There problem it's that ssh key for vagrant it's not your key, it's a key on Homestead directory.

Solution for me:

• Use vagrant / vagrant for access ti VM of Homestead
• vagrant ssh-config for see config of ssh

run on terminal

vagrant ssh-config
Host default
HostName 127.0.0.1
User vagrant
Port 2222
UserKnownHostsFile /dev/null
StrictHostKeyChecking no
PasswordAuthentication no
IdentityFile "/Users/MYUSER/.vagrant.d/insecure_private_key"
IdentitiesOnly yes
LogLevel FATAL
ForwardAgent yes

Create a new pair of SSH keys

ssh-keygen -f /Users/MYUSER/.vagrant.d/insecure_private_key

Copy content of public key

cat /Users/MYUSER/.vagrant.d/insecure_private_key.pub

On other shell in Homestead VM Machine copy into authorized_keys

vagrant@homestad:~$ echo 'CONTENT_PASTE_OF_PRIVATE_KEY' >> ~/.ssh/authorized_keys

Now can access with vagrant ssh

For Swift:

self.tableView.tableFooterView = UIView(frame: CGRectZero)

For newest Swift:

self.tableView.tableFooterView = UIView(frame: CGRect.zero)

The character is a backslash \

From the bash manual:

The backslash character ‘\’ may be used to remove any special meaning for the next character read and for line continuation.

Nice topic. Well, I have done so. In XML file:

<EditText
    ...
    android:editable="false"
    android:inputType="none" />

In Java-code:

txtDay.setOnClickListener(onOnClickEvent);
txtDay.setOnFocusChangeListener(onFocusChangeEvent);

private View.OnClickListener onOnClickEvent = new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        dpDialog.show();
    }
};
private View.OnFocusChangeListener onFocusChangeEvent = new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if (hasFocus)
            dpDialog.show();
    }
};

Array elements in Java are initialized to default values when created. For numbers this means they are initialized to 0, for references they are null and for booleans they are false.

To fill the array with something else you can use Arrays.fill() or as part of the declaration

int[] a = new int[] {0, 0, 0, 0};

There are no shortcuts in Java to fill arrays with arithmetic series as in some scripting languages.

If you need an algorithm, try this: Convert the color from RGB space to HSV space (Hue, Saturation, Value). If your UI framework can't do it, check this article: http://en.wikipedia.org/wiki/HSL_and_HSV#Conversion_from_RGB_to_HSL_or_HSV

Hue is in [0,360). To find the "opposite" color (think colorwheel), just add 180 degrees:

h = (h + 180) % 360;

For saturation and value, invert them:

l = 1.0 - l;
v = 1.0 - v;

Convert back to RGB. This should always give you a high contrast even though most combinations will look ugly.

If you want to avoid the "ugly" part, build a table with several "good" combinations, find the one with the least difference

def q(x):
    return x*x
def diff(col1, col2):
    return math.sqrt(q(col1.r-col2.r) + q(col1.g-col2.g) + q(col1.b-col2.b))

and use that.

I had the same issue and thought it can be simply solved by a cron job calling unattended-upgrade daily.

My intention is to have this as an automatic and quick solution to ensure that production container is secure and updated because it can take me sometime to update my images and deploy a new docker image with the latest security updates.

It is also possible to automate the image build and deployment with Github hooks

I've created a basic docker image with that automatically checks and installs security updates daily (can run directly by docker run itech/docker-unattended-upgrade ).

I also came across another different approach to check if the container needs an update.

My complete implementation:

Dockerfile

FROM ubuntu:14.04   

RUN apt-get update \
&& apt-get install -y supervisor unattended-upgrades \
&& rm -rf /var/lib/apt/lists/*

COPY install /install
RUN chmod 755 install
RUN /install

COPY start /start
RUN chmod 755 /start

Helper scripts

install

#!/bin/bash
set -e

cat > /etc/supervisor/conf.d/cron.conf <<EOF
[program:cron]
priority=20
directory=/tmp
command=/usr/sbin/cron -f
user=root
autostart=true
autorestart=true
stdout_logfile=/var/log/supervisor/%(program_name)s.log
stderr_logfile=/var/log/supervisor/%(program_name)s.log
EOF

rm -rf /var/lib/apt/lists/*

ENTRYPOINT ["/start"]

start

#!/bin/bash

set -e

echo "Adding crontab for unattended-upgrade ..."
echo "0 0 * * * root /usr/bin/unattended-upgrade" >> /etc/crontab

# can also use @daily syntax or use /etc/cron.daily

echo "Starting supervisord ..."
exec /usr/bin/supervisord -n -c /etc/supervisor/supervisord.conf

Edit

I developed a small tool docker-run that runs as docker container and can be used to update packages inside all or selected running containers, it can also be used to run any arbitrary commands.

Can be easily tested with the following command:

docker run --rm -v /var/run/docker.sock:/tmp/docker.sock itech/docker-run exec

which by default will execute date command in all running containers and display the results. If you pass update instead of exec it will execute apt-get update followed by apt-get upgrade -y in all running containers

It feels like that HEAD is just a tag for the last commit that you checked out.

This can be the tip of a specific branch (such as "master") or some in-between commit of a branch ("detached head")

I had the same issue.

During the 1st development I used a .csv file (comma as separator) that I've modified a bit before saving it. After saving the commas became semicolon.

On Windows it is dependent on the "Regional and Language Options" customize screen where you find a List separator. This is the char Windows applications expect to be the CSV separator.

When testing from a brand new file I encountered that issue.

I've removed the 'sep' argument in read_csv method before:

df1 = pd.read_csv('myfile.csv', sep=',');

after:

df1 = pd.read_csv('myfile.csv');

That way, the issue disappeared.

I am just beginning to dig deeper into git, so not sure if I understand correctly, but I think the correct answer to the OP's question is that you can run git log --all with a format specification like this: git log --all --pretty=format:'%h: %s %d'. This marks the current checked out version as (HEAD) and you can just grab the next one from the list.

BTW, add an alias like this to your .gitconfig with a slightly better format and you can run git hist --all:

  hist = log --pretty=format:\"%h %ai | %s%d [%an]\" --graph

Regarding the relative versions, I found this post, but it only talks about older versions, there is probably nothing to refer to the newer versions.

Working Method from HONEYCOMB (API 11) to Oreo(API 27)

static WebView mWebView;
private ValueCallback<Uri> mUploadMessage;
public ValueCallback<Uri[]> uploadMessage;
public static final int REQUEST_SELECT_FILE = 100;
private final static int FILECHOOSER_RESULTCODE = 1;

Modified onActivityResult()

@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent)
{
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
    {
        if (requestCode == REQUEST_SELECT_FILE)
        {
            if (uploadMessage == null)
                return;

Now in onCreate() or onCreateView() paste the following code

    }
});

This works for me

v.getBackground().setTint(Color.parseColor("#212121"));

That way only changes the color of the background without change the background itself. This is usefull for example if you have a background with rounded corners.

Try setting a Windows System Environment variable called _JAVA_OPTIONS with the heap size you want. Java should be able to find it and act accordingly.

The BASE acronym was defined by Eric Brewer, who is also known for formulating the CAP theorem.

The CAP theorem states that a distributed computer system cannot guarantee all of the following three properties at the same time:

• Consistency
• Availability
• Partition tolerance

A BASE system gives up on consistency.

• Basically available indicates that the system does guarantee availability, in terms of the CAP theorem.
• Soft state indicates that the state of the system may change over time, even without input. This is because of the eventual consistency model.
• Eventual consistency indicates that the system will become consistent over time, given that the system doesn't receive input during that time.

Brewer does admit that the acronym is contrived:

I came up with [the BASE] acronym with my students in their office earlier that year. I agree it is contrived a bit, but so is "ACID" -- much more than people realize, so we figured it was good enough.

As per you said your both files are in same directory. 1. index.html and 2. style.css

I have copied your code and run it in my local machine its working fine there is no issues.

According to me your browser is not refreshing the file so you can refresh/reload the entire page by pressing CTRL + F5 in windows for mac CMD + R.

Try it if still getting problem then you can test it by using firebug tool for firefox.

For IE8 and Google Chrome you can check it by pressing F12 your developer tool will pop-up and you can see the Html and css.

Still you have any problem please comment so we can help you.

Sure you just need to setup a local web server. Check out XAMPP: http://www.apachefriends.org/en/xampp.html

That will get you up and running in about 10 minutes.

There is now a way to run php locally without installing a server: https://stackoverflow.com/a/21872484/672229

Yes but the files need to be processed. For example you can install test servers like mamp / lamp / wamp depending on your plateform.

Basically you need apache / php running.

cmake's ExternalProject_Add indeed can used, but what I did not like about it - is that it performs something during build, continuous poll, etc... I would prefer to build project during build phase, nothing else. I have tried to override ExternalProject_Add in several attempts, unfortunately without success.

Then I have tried also to add git submodule, but that drags whole git repository, while in certain cases I need only subset of whole git repository. What I have checked - it's indeed possible to perform sparse git checkout, but that require separate function, which I wrote below.

#-----------------------------------------------------------------------------
#
# Performs sparse (partial) git checkout
#
#   into ${checkoutDir} from ${url} of ${branch}
#
# List of folders and files to pull can be specified after that.
#-----------------------------------------------------------------------------
function (SparseGitCheckout checkoutDir url branch)
    if(EXISTS ${checkoutDir})
        return()
    endif()

    message("-------------------------------------------------------------------")
    message("sparse git checkout to ${checkoutDir}...")
    message("-------------------------------------------------------------------")

    file(MAKE_DIRECTORY ${checkoutDir})

    set(cmds "git init")
    set(cmds ${cmds} "git remote add -f origin --no-tags -t master ${url}")
    set(cmds ${cmds} "git config core.sparseCheckout true")

    # This command is executed via file WRITE
    # echo <file or folder> >> .git/info/sparse-checkout")

    set(cmds ${cmds} "git pull --depth=1 origin ${branch}")

    # message("In directory: ${checkoutDir}")

    foreach( cmd ${cmds})
        message("- ${cmd}")
        string(REPLACE " " ";" cmdList ${cmd})

        #message("Outfile: ${outFile}")
        #message("Final command: ${cmdList}")

        if(pull IN_LIST cmdList)
            string (REPLACE ";" "\n" FILES "${ARGN}")
            file(WRITE ${checkoutDir}/.git/info/sparse-checkout ${FILES} )
        endif()

        execute_process(
            COMMAND ${cmdList}
            WORKING_DIRECTORY ${checkoutDir}
            RESULT_VARIABLE ret

        if(NOT ret EQUAL "0")
            message("error: previous command failed, see explanation above")
            file(REMOVE_RECURSE ${checkoutDir})
            break()
        endif()
    endforeach()

endfunction()


SparseGitCheckout(${CMAKE_BINARY_DIR}/catch_197 https://github.com/catchorg/Catch2.git v1.9.7 single_include)
SparseGitCheckout(${CMAKE_BINARY_DIR}/catch_master https://github.com/catchorg/Catch2.git master single_include)

I have added two function calls below just to illustrate how to use the function.

Someone might not like to checkout master / trunk, as that one might be broken - then it's always possible to specify specific tag.

Checkout will be performed only once, until you clear the cache folder.

This is just additional information for this answer.

If you are using nginx, you would add proxy_set_header X-Real-IP $remote_addr; to the location block for the site. /etc/nginx/sites-available/www.example.com for example. Here is a example server block.

server {
    listen 80;
    listen [::]:80;

    server_name example.com www.example.com;

    location / {
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_pass http://127.0.1.1:3080;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

After restarting nginx, you will be able to access the ip in your node/express application routes with req.headers['x-real-ip'] || req.connection.remoteAddress;

Use event.key and modern JS!

$(document).keypress(function(event) {
    if (event.key === "Enter") {
        // Do something
    }
});

or without jQuery:

I'm not entirely sure if I understood your question, but it seems that you're trying to set value for an input type Date.

If you want to set a value for an input type 'Date', then it has to be formatted as "yyyy-MM-dd" (Note: capital MM for Month, lower case mm for minutes). Otherwise, it will clear the value and leave the datepicker empty.

Let's say you have a button called "DateChanger" and you want to set your datepicker to "22 Dec 2012" when you click it.

<script>
    $(document).ready(function () {
        $('#DateChanger').click(function() {
             $('#dtFrom').val("2012-12-22");
        });
    });
</script>
<input type="date" id="dtFrom" name="dtFrom" />
<button id="DateChanger">Click</button>

Remember to include JQuery reference.

Extract Day, Month and Year

The highest voted function and the accepted one do NOT work locale-independently since the DATE command is subject to localization too. For example (the accepted one): In English you have YYYY for year and in Holland it is JJJJ. So this is a no-go. The following script takes the users' localization from the registry, which is locale-independent.

@echo off

::: Begin set date
setlocal EnableExtensions EnableDelayedExpansion

:: Determine short date format (independent from localization) from registry
for /f "skip=1 tokens=3-5 delims=- " %%L in ( '2^>nul reg query "HKCU\Control Panel\International" /v "sShortDate"' ) do ( 

    :: Since we can have multiple (short) date formats we only use the first char from the format in a new variable
    set "_L=%%L" && set "_L=!_L:~0,1!" && set "_M=%%M" && set "_M=!_M:~0,1!" && set "_N=%%N" && set "_N=!_N:~0,1!"

    :: Now assign the date values to the new vars
    for /f "tokens=2-4 delims=/-. " %%D in ( "%date%" ) do ( set "!_L!=%%D" && set "!_M!=%%E" && set "!_N!=%%F" )
)


:: Print the values as is
echo.
echo This is the original date string --^> %date%
echo These are the splitted values    --^> Day: %d%, Month:%m%, Year: %y%.
echo.

endlocal

Extract only the Year

For a script I wrote I wanted only to extract the year (locale-independent) so I came up with this oneliner as I couldn't find any solution. It uses the 'DATE' var, multiple delimiters and checks for a number greater than 31. That then will be the current year. It's low on resources in contrast to some of the other solutions.

@echo off

setlocal EnableExtensions

for /f " tokens=2-4 delims=-./ " %%D in ( "%date%" ) do ( if %%D gtr 31 ( set "_YEAR=%%D" ) else ( if %%E gtr 31 ( set "_YEAR=%%E" ) else ( if %%F gtr 31 ( set "_YEAR=%%F" ) ) ) )

echo And the year is... %_YEAR%.
echo.

endlocal

Try this:

num_days = later_date - earlier_date

Use -qscale:v to control quality

Use -qscale:v (or the alias -q:v) as an output option.

• Normal range for JPEG is 2-31 with 31 being the worst quality.
• The scale is linear with double the qscale being roughly half the bitrate.
• Recommend trying values of 2-5.
• You can use a value of 1 but you must add the -qmin 1 output option (because the default is -qmin 2).

To output a series of images:

ffmpeg -i input.mp4 -qscale:v 2 output_%03d.jpg

See the image muxer documentation for more options involving image outputs.

To output a single image at ~60 seconds duration:

ffmpeg -ss 60 -i input.mp4 -qscale:v 4 -frames:v 1 output.jpg

Taking @Ants Aasmas answer one step further, you can create a wrapper that takes any method call and forwards it to all elements of a given list:

class AllOf:
    def __init__(self, elements):
        self.elements = elements
    def __getattr__(self, attr):
        def on_all(*args, **kwargs):
            for obj in self.elements:
                getattr(obj, attr)(*args, **kwargs)
        return on_all

That class can then be used like this:

class Foo:
    def __init__(self, val="quux!"):
        self.val = val
    def foo(self):
        print "foo: " + self.val

a = [ Foo("foo"), Foo("bar"), Foo()]
AllOf(a).foo()

Which produces the following output:

foo: foo
foo: bar
foo: quux!

With some work and ingenuity it could probably be enhanced to handle attributes as well (returning a list of attribute values).

ax.set_title() should set the titles for separate subplots:

import matplotlib.pyplot as plt

if __name__ == "__main__":
    data = [1, 2, 3, 4, 5]

    fig = plt.figure()
    fig.suptitle("Title for whole figure", fontsize=16)
    ax = plt.subplot("211")
    ax.set_title("Title for first plot")
    ax.plot(data)

    ax = plt.subplot("212")
    ax.set_title("Title for second plot")
    ax.plot(data)

    plt.show()

Can you check if this code works for you? Maybe something overwrites them later?

SELECT REVERSE(ROUND(REVERSE(2.5500),1))

prints:

2.55

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

Example of a basic OptionMenu:

from Tkinter import *

master = Tk()

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

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

mainloop()

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

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

from tkinter import *

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

master = Tk()

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

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

mainloop()

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

from tkinter import *

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

master = Tk()

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

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

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

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

mainloop()

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

This error comes when you append this line os.path.join(os.path.dirname(__file__)) in python interactive shell.

Python Shell doesn't detect current file path in __file__ and it's related to your filepath in which you added this line

So you should write this line os.path.join(os.path.dirname(__file__)) in file.py. and then run python file.py, It works because it takes your filepath.

Add these two file in your app.module.ts

import { FileTransfer } from '@ionic-native/file-transfer';
import { File } from '@ionic-native/file';

after that declare these to in provider..

providers: [
    Api,
    Items,
    User,
    Camera,
    File,
    FileTransfer];

This is work for me.

skip.header.line.count will skip the header line.

However, if you have some external tool accessing accessing the table, it will still see that actual data without skipping those lines

Just had the same problem myself.

What happens is, that even if you drop the database, innodb will still not release disk space. I had to export, stop mysql, remove the files manually, start mysql, create database and users, and then import. Thank god I only had 200MB worth of rows, but it spared 250GB of innodb file.

Fail by design.

Similar to tight_layout matplotlib now (as of version 2.2) provides constrained_layout. In contrast to tight_layout, which may be called any time in the code for a single optimized layout, constrained_layout is a property, which may be active and will optimze the layout before every drawing step.

Hence it needs to be activated before or during subplot creation, such as figure(constrained_layout=True) or subplots(constrained_layout=True).

Example:

import matplotlib.pyplot as plt

fig, axes = plt.subplots(4,4, constrained_layout=True)

plt.show()

constrained_layout may as well be set via rcParams

plt.rcParams['figure.constrained_layout.use'] = True

See the what's new entry and the Constrained Layout Guide

probably the onclick handler should read onclick='hello();' instead of onclick=hello();

If You want to import settings on PuTTY Portable You can use the putty.reg file.

Just put it to this path [path_to_Your_portable_apps]PuTTYPortable\Data\settings\putty.reg. Program will import it

Generally, I do this command "adb shell ps" in prompt (allows to see processes running) and it's possible to discover aplication's pid. With this pid in hands, go to Eclipse and write pid:XXXX (XXXX is the application pid) then logs output is filtered by this application.

Or, in a easier way... in logcat view on Eclipse, search for any word related with your desired application, discover the pid, and then do a filter by pid "pid:XXXX".

You can query sqlite_master

SELECT sql FROM sqlite_master WHERE name='foo';

which will return a create table SQL statement, for example:

$ sqlite3 mydb.sqlite
sqlite> create table foo (id int primary key, name varchar(10));
sqlite> select sql from sqlite_master where name='foo';
CREATE TABLE foo (id int primary key, name varchar(10))

sqlite> .schema foo
CREATE TABLE foo (id int primary key, name varchar(10));

sqlite> pragma table_info(foo)
0|id|int|0||1
1|name|varchar(10)|0||0

It seems like sometime during the second half of 2018 many php packages such as php-mysql and phpmyadmin were removed or changed. I faced that same problem too. So you'll have to download it from another source or find out the new packages

De esta forma Jquery obtiene solo el elemento checked

$('input[name="radioInline"]:checked').val()

I believe this is the most simple in all aspects unless you call the validate function be other means. With no/null/empty value to your first option is easier to validate. You could also eliminate the first option and start with the most popular card type.

<form name="myForm">
<select id="cardtype" name="cards">
<option value="">--- Please select ---</option>
<option value="mastercard" selected="selected">Mastercard</option>
<option value="maestro">Maestro</option>
<option value="solo">Solo (UK only)</option>
<option value="visaelectron">Visa Electron</option>
<option value="visadebit">Visa Debit</option>
</select><br />

<input type="submit" name="submit" class="button" value="SUBMIT" onmouseover="validate()"></form>

<script>
function validate() {
 if (document.myform.cards.value == "") {
    alert("Please select a card type");
    document.myForm.cards.focus();
}
</script>

If we look at the implementation of the equalsIgnoreCase method, we find this part:

if (string == null || count != string.count) {
    return false;
}

So it will always return false if the argument is null. And this is obviously right, because the only case where it should return true is when equalsIgnoreCase was invoked on a null String, but

String nullString = null;
nullString.equalsIgnoreCase(null);

will definitely result in a NullPointerException.

So equals methods are not designed to test whether an object is null, just because you can't invoke them on null.

Checkboxes are a control type designed for one purpose: to ensure valid entry of Boolean values.

In Access, there are two types:

1. 2-state -- can be checked or unchecked, but not Null. Values are True (checked) or False (unchecked). In Access and VBA, the value of True is -1 and the value of False is 0. For portability with environments that use 1 for True, you can always test for False or Not False, since False is the value 0 for all environments I know of.

2. 3-state -- like the 2-state, but can be Null. Clicking it cycles through True/False/Null. This is for binding to an integer field that allows Nulls. It is of no use with a Boolean field, since it can never be Null.

Minor quibble with the answers:

There is almost never a need to use the .Value property of an Access control, as it's the default property. These two are equivalent:

  ?Me!MyCheckBox.Value
  ?Me!MyCheckBox

The only gotcha here is that it's important to be careful that you don't create implicit references when testing the value of a checkbox. Instead of this:

  If Me!MyCheckBox Then

...write one of these options:

  If (Me!MyCheckBox) Then  ' forces evaluation of the control

  If Me!MyCheckBox = True Then

  If (Me!MyCheckBox = True) Then

  If (Me!MyCheckBox = Not False) Then

Likewise, when writing subroutines or functions that get values from a Boolean control, always declare your Boolean parameters as ByVal unless you actually want to manipulate the control. In that case, your parameter's data type should be an Access control and not a Boolean value. Anything else runs the risk of implicit references.

Last of all, if you set the value of a checkbox in code, you can actually set it to any number, not just 0 and -1, but any number other than 0 is treated as True (because it's Not False). While you might use that kind of thing in an HTML form, it's not proper UI design for an Access app, as there's no way for the user to be able to see what value is actually be stored in the control, which defeats the purpose of choosing it for editing your data.

Let's start out with some definitions first:

Interface n. The set of all signatures defined by an object's operations is called the interface to the object

Type n. A particular interface

A simple example of an interface as defined above would be all the PDO object methods such as query(), commit(), close() etc., as a whole, not separately. These methods, i.e. its interface define the complete set of messages, requests that can be sent to the object.

A type as defined above is a particular interface. I will use the made-up shape interface to demonstrate: draw(), getArea(), getPerimeter() etc..

If an object is of the Database type we mean that it accepts messages/requests of the database interface, query(), commit() etc.. Objects can be of many types. You can have a database object be of the shape type as long as it implements its interface, in which case this would be sub-typing.

Many objects can be of many different interfaces/types and implement that interface differently. This allows us to substitute objects, letting us choose which one to use. Also known as polymorphism.

The client will only be aware of the interface and not the implementation.

So in essence programming to an interface would involve making some type of abstract class such as Shape with the interface only specified i.e. draw(), getCoordinates(), getArea() etc.. And then have different concrete classes implement those interfaces such as a Circle class, Square class, Triangle class. Hence program to an interface not an implementation.

You need to tell scp where to send the file. In your command that is not working:

scp C:\Users\Admin\Desktop\WMU\5260\A2.c ~

You have not mentioned a remote server. scp uses : to delimit the host and path, so it thinks you have asked it to download a file at the path \Users\Admin\Desktop\WMU\5260\A2.c from the host C to your local home directory.

The correct upload command, based on your comments, should be something like:

C:\> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:

If you are running the command from your home directory, you can use a relative path:

C:\Users\Admin> pscp Desktop\WMU\5260\A2.c [email protected]:

You can also mention the directory where you want to this folder to be downloaded to at the remote server. i.e by just adding a path to the folder as below:

C:/> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:/home/path_to_the_folder/

Try:

sudo apt-get install python-tk python3-tk tk-dev

If you're using python3, then Python3 virtual environment(venv) is also required. Use:

sudo apt install python3-venv

For a <input type='text'> element:

input { font-size: 18px; }

or for a <textarea>:

textarea { font-size: 18px; }

or for a <select>:

select { font-size: 18px; }

you get the drift.

To solve the issue of customisation and appearance of the ticks, see the Tick Locators guide on the matplotlib website

ax.xaxis.set_major_locator(plt.MaxNLocator(3))

Would set the total number of ticks in the x-axis to 3, and evenly distribute it across the axis.

There is also a nice tutorial about this

If you use OmniFaces you can also use it's EL functions like of:formatDate() to format Date objects. You would use it like this:

<h:outputText value="#{of:formatDate(someBean.dateField, 'dd.MM.yyyy HH:mm')}" />

This way you can not only use it for output but also to pass it on to other JSF components.

Hold everything. When's the last time you programed your calculator to play tetris? Did you actually think you could write anything you want in those 128k of RAM? Likely not. MATLAB is not for programming unless you're dealing with huge matrices. It's the graphing calculator you whip out when you've got Megabytes to Gigabytes of data to crunch and/or plot. Learn just basic stuff, but also don't kill yourself trying to make Python be a graphing calculator.

You'll quickly get a feel for when you want to crunch, plot or explore in MATLAB and when you want to have all that Python offers. Lots of engineers turn to pre and post processing in Python or Perl. Occasionally even just calling out to MATLAB for the hard bits.

They are such completely different tools that you should learn their basic strengths first without trying to replace one with the other. Granted for saving money I'd either use Octave or skimp on ease and learn to work with sparse matrices in Perl or Python.

If your exe takes arguments,

Which version of bootstrap are you using? The early versions of Bootstrap 3 (3.0, 3.0.1) didn't work with this functionality.

col-md-offset-0 should be working as seen in this bootstrap example found here (http://getbootstrap.com/css/#grid-responsive-resets):

<div class="row">
   <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
   <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

Background

You can use the base64 CLI tool to generate the base64 encoded version of your username + password like this:

$ echo -n "joeuser:secretpass" | base64
am9ldXNlcjpzZWNyZXRwYXNz

-or-

$ base64 <<<"joeuser:secretpass"
am9ldXNlcjpzZWNyZXRwYXNzCg==

Base64 is reversible so you can also decode it to confirm like this:

$ echo -n "joeuser:secretpass" | base64 | base64 -D
joeuser:secretpass

-or-

$ base64 <<<"joeuser:secretpass" | base64 -D
joeuser:secretpass

NOTE: username = joeuser, password = secretpass

Example #1 - using -H

You can put this together into curl like this:

$ curl -H "Authorization: Basic $(base64 <<<"joeuser:secretpass")" http://example.com

Example #2 - using -u

Most will likely agree that if you're going to bother doing this, then you might as well just use curl's -u option.

$ curl --help |grep -- "--user "
 -u, --user USER[:PASSWORD]  Server user and password

For example:

$ curl -u someuser:secretpass http://example.com

But you can do this in a semi-safer manner if you keep your credentials in a encrypted vault service such as LastPass or Pass.

For example, here I'm using the LastPass' CLI tool, lpass, to retrieve my credentials:

$ curl -u $(lpass show --username example.com):$(lpass show --password example.com) \
     http://example.com

Example #3 - using curl config

There's an even safer way to hand your credentials off to curl though. This method makes use of the -K switch.

$ curl -X GET -K \
    <(cat <<<"user = \"$(lpass show --username example.com):$(lpass show --password example.com)\"") \
    http://example.com

When used, your details remain hidden, since they're passed to curl via a temporary file descriptor, for example:

+ curl -skK /dev/fd/63 -XGET -H 'Content-Type: application/json' https://es-data-01a.example.com:9200/_cat/health
++ cat
+++ lpass show --username example.com
+++ lpass show --password example.com

NOTE: Above I'm communicating with one of our Elasticsearch nodes, inquiring about the cluster's health.

This method is dynamically creating a file with the contents user = "<username>:<password>" and giving that to curl.

HTTP Basic Authorization

The methods shown above are facilitating a feature known as Basic Authorization that's part of the HTTP standard.

When the user agent wants to send authentication credentials to the server, it may use the Authorization field.

The Authorization field is constructed as follows:

1. The username and password are combined with a single colon (:). This means that the username itself cannot contain a colon.
2. The resulting string is encoded into an octet sequence. The character set to use for this encoding is by default unspecified, as long as it is compatible with US-ASCII, but the server may suggest use of UTF-8 by sending the charset parameter.
3. The resulting string is encoded using a variant of Base64.
4. The authorization method and a space (e.g. "Basic ") is then prepended to the encoded string.

For example, if the browser uses Aladdin as the username and OpenSesame as the password, then the field's value is the base64-encoding of Aladdin:OpenSesame, or QWxhZGRpbjpPcGVuU2VzYW1l. Then the Authorization header will appear as:

Authorization: Basic QWxhZGRpbjpPcGVuU2VzYW1l

Source: Basic access authentication

This is a way to determine it for all css properties including visibility:

html:

<div id="element">div content</div>

css:

#element
{
visibility:hidden;
}

javascript:

var element = document.getElementById('element');
 if(element.style.visibility == 'hidden'){
alert('hidden');
}
else
{
alert('visible');
}

It works for any css property and is very versatile and reliable.

use the .size() method or .length attribute

The problem is that undefined compared to null using == gives true. The common check for undefined is therefore done like this:

typeof x == "undefined"

this ensures the type of the variable is really undefined.

You need to find out the actual reason for this common error code: 1004. Edit your function/VBA code and run your program in debug mode to identify the line which is causing it. And then, add below piece of code to see the error,

On Error Resume Next
//Your Line here which causes 1004 error
If Err.Number > 0 Then
  Debug.Print Err.Number & ":" & Err.Description
End If

Note: Debug shortcut keys i use in PC: Step Into (F8), Step Over (Shift + F8), Step Out (Ctrl + Shift + F8)

//Element[@attribute1="abc" and @attribute2="xyz" and .="Data"]

The reason why I add this answer is that I want to explain the relationship of . and text() .

The first thing is when using [], there are only two types of data:

1. [number] to select a node from node-set
2. [bool] to filter a node-set from node-set

In this case, the value is evaluated to boolean by function boolean(), and there is a rule:

Filters are always evaluated with respect to a context.

When you need to compare text() or . with a string "Data", it first uses string() function to transform those to string type, than gets a boolean result.

There are two important rule about string():

1. The string() function converts a node-set to a string by returning the string value of the first node in the node-set, which in some instances may yield unexpected results.

   text() is relative path that return a node-set contains all the text node of current node(context node), like ["Data"]. When it is evaluated by string(["Data"]), it will return the first node of node-set, so you get "Data" only when there is only one text node in the node-set.

2. If you want the string() function to concatenate all child text, you must then pass a single node instead of a node-set.

   For example, we get a node-set ['a', 'b'], you can pass there parent node to string(parent), this will return 'ab', and of cause string(.) in you case will return an concatenated string "Data".

Both way will get same result only when there is a text node.

Use the -s or --strategy option combined with the -X option. In your specific question, you want to keep all of the remote files and replace the local files of the same name.

Replace conflicts with the remote version

git merge -s recursive -Xtheirs upstream/master  

will use the remote repo version of all conflicting files.

Replace conflicts with the local version

git merge -s recursive -Xours upstream/master

will use the local repo version of all conflicting files.

How about?

function callHttpService(url, params){
  // Assume params contains key/value request params
  let queryStrings = '';

  for(let key in params){
      queryStrings += `${key}=${params[key]}&`
    } 
 const fullUrl = `${url}?queryStrings`

  //make http request with fullUrl
}

An Error usually shouldn't be caught, as it indicates an abnormal condition that should never occur.

From the Java API Specification for the Error class:

An Error is a subclass of Throwable that indicates serious problems that a reasonable application should not try to catch. Most such errors are abnormal conditions. [...]

A method is not required to declare in its throws clause any subclasses of Error that might be thrown during the execution of the method but not caught, since these errors are abnormal conditions that should never occur.

As the specification mentions, an Error is only thrown in circumstances that are Chances are, when an Error occurs, there is very little the application can do, and in some circumstances, the Java Virtual Machine itself may be in an unstable state (such as VirtualMachineError)

Although an Error is a subclass of Throwable which means that it can be caught by a try-catch clause, but it probably isn't really needed, as the application will be in an abnormal state when an Error is thrown by the JVM.

There's also a short section on this topic in Section 11.5 The Exception Hierarchy of the Java Language Specification, 2nd Edition.

First, HTML and PDF are not related although they were created around the same time. HTML is intended to convey higher level information such as paragraphs and tables. Although there are methods to control it, it is ultimately up to the browser to draw these higher level concepts. PDF is intended to convey documents and the documents must "look" the same wherever they are rendered.

In an HTML document you might have a paragraph that's 100% wide and depending on the width of your monitor it might take 2 lines or 10 lines and when you print it it might be 7 lines and when you look at it on your phone it might take 20 lines. A PDF file, however, must be independent of the rendering device, so regardless of your screen size it must always render exactly the same.

Because of the musts above, PDF doesn't support abstract things like "tables" or "paragraphs". There are three basic things that PDF supports: text, lines/shapes and images. (There are other things like annotations and movies but I'm trying to keep it simple here.) In a PDF you don't say "here's a paragraph, browser do your thing!". Instead you say, "draw this text at this exact X,Y location using this exact font and don't worry, I've previously calculated the width of the text so I know it will all fit on this line". You also don't say "here's a table" but instead you say "draw this text at this exact location and then draw a rectangle at this other exact location that I've previously calculated so I know it will appear to be around the text".

Second, iText and iTextSharp parse HTML and CSS. That's it. ASP.Net, MVC, Razor, Struts, Spring, etc, are all HTML frameworks but iText/iTextSharp is 100% unaware of them. Same with DataGridViews, Repeaters, Templates, Views, etc. which are all framework-specific abstractions. It is your responsibility to get the HTML from your choice of framework, iText won't help you. If you get an exception saying The document has no pages or you think that "iText isn't parsing my HTML" it is almost definite that you don't actually have HTML, you only think you do.

Third, the built-in class that's been around for years is the HTMLWorker however this has been replaced with XMLWorker (Java / .Net). Zero work is being done on HTMLWorker which doesn't support CSS files and has only limited support for the most basic CSS properties and actually breaks on certain tags. If you do not see the HTML attribute or CSS property and value in this file then it probably isn't supported by HTMLWorker. XMLWorker can be more complicated sometimes but those complications also make it more extensible.

Below is C# code that shows how to parse HTML tags into iText abstractions that get automatically added to the document that you are working on. C# and Java are very similar so it should be relatively easy to convert this. Example #1 uses the built-in HTMLWorker to parse the HTML string. Since only inline styles are supported the class="headline" gets ignored but everything else should actually work. Example #2 is the same as the first except it uses XMLWorker instead. Example #3 also parses the simple CSS example.

2017's update

There are good news for HTML-to-PDF demands. As this answer showed, the W3C standard css-break-3 will solve the problem... It is a Candidate Recommendation with plan to turn into definitive Recommendation this year, after tests.

As not-so-standard there are solutions, with plugins for C#, as showed by print-css.rocks.

For those who didn't know already, you would have to put the declare statement outside your class just like this:

declare var Chart: any;

@Component({
  selector: 'my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.scss']
})

export class MyComponent {
    //you can use Chart now and compiler wont complain
    private color = Chart.color;
}

In TypeScript the declare keyword is used where you want to define a variable that may not have originated from a TypeScript file.

It is like you tell the compiler that, I know this variable will have a value at runtime, so don't throw a compilation error.

There are a few different ways to accomplish this, I'll outline my favourites.

Use a ToggleButton and apply a custom style to it. I suggest this because your required control is "like a toggle button" but just looks different from the default toggle button styling.

My preferred method is to define a graphic for the button in css:

.toggle-button {
  -fx-graphic: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Pizza-icon.png');
}

.toggle-button:selected {
  -fx-graphic: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Piece-of-cake-icon.png');
}

OR use the attached css to define a background image.

// file imagetogglebutton.css deployed in the same package as ToggleButtonImage.class
.toggle-button {
  -fx-background-image: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Pizza-icon.png');
  -fx-background-repeat: no-repeat;
  -fx-background-position: center;
}

.toggle-button:selected {
  -fx-background-image: url('http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Piece-of-cake-icon.png');
}

I prefer the -fx-graphic specification over the -fx-background-* specifications as the rules for styling background images are tricky and setting the background does not automatically size the button to the image, whereas setting the graphic does.

And some sample code:

import javafx.application.Application;
import javafx.scene.*;
import javafx.scene.control.ToggleButton;
import javafx.scene.layout.StackPaneBuilder;
import javafx.stage.Stage;

public class ToggleButtonImage extends Application {
  public static void main(String[] args) throws Exception { launch(args); }
  @Override public void start(final Stage stage) throws Exception {
    final ToggleButton toggle = new ToggleButton();
    toggle.getStylesheets().add(this.getClass().getResource(
      "imagetogglebutton.css"
    ).toExternalForm());
    toggle.setMinSize(148, 148); toggle.setMaxSize(148, 148);
    stage.setScene(new Scene(
      StackPaneBuilder.create()
        .children(toggle)
        .style("-fx-padding:10; -fx-background-color: cornsilk;")
        .build()
    ));
    stage.show();
  }
}

Some advantages of doing this are:

1. You get the default toggle button behavior and don't have to re-implement it yourself by adding your own focus styling, mouse and key handlers etc.
2. If your app gets ported to different platform such as a mobile device, it will work out of the box responding to touch events rather than mouse events, etc.
3. Your styling is separated from your application logic so it is easier to restyle your application.

An alternate is to not use css and still use a ToggleButton, but set the image graphic in code:

import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.scene.*;
import javafx.scene.control.ToggleButton;
import javafx.scene.image.*;
import javafx.scene.layout.StackPaneBuilder;
import javafx.stage.Stage;

public class ToggleButtonImageViaGraphic extends Application {
  public static void main(String[] args) throws Exception { launch(args); }
  @Override public void start(final Stage stage) throws Exception {
    final ToggleButton toggle      = new ToggleButton();
    final Image        unselected  = new Image(
      "http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Pizza-icon.png"
    );
    final Image        selected    = new Image(
      "http://icons.iconarchive.com/icons/aha-soft/desktop-buffet/128/Piece-of-cake-icon.png"
    );
    final ImageView    toggleImage = new ImageView();
    toggle.setGraphic(toggleImage);
    toggleImage.imageProperty().bind(Bindings
      .when(toggle.selectedProperty())
        .then(selected)
        .otherwise(unselected)
    );

    stage.setScene(new Scene(
      StackPaneBuilder.create()
        .children(toggle)
        .style("-fx-padding:10; -fx-background-color: cornsilk;")
        .build()
    ));
    stage.show();
  }
}

The code based approach has the advantage that you don't have to use css if you are unfamilar with it.

For best performance and ease of porting to unsigned applet and webstart sandboxes, bundle the images with your app and reference them by relative path urls rather than downloading them off the net.

I guess this may be an issue about limited contexts, e.g. WYIWYG editors on a web system used by not-programmers users, that limits the possibilities of follow the standards. Sometimes (like TinyMCE), it's a lib that puts your content/code inside a textarea tag, that is rendered by the editor as a big div tag. And sometimes, it may be an old version of these editors.

I'm supposing that:

1. these not-programmers users don't have an open channel with the system admins (or institution's webdevs), to ask for including some CSS rules at the system's stylesheets. Actually, it would be impractical for the admins (or webdevs), considering the number of requests in that sense that they would have.
2. this system is legacy and still doesn't support newer versions of HTML.

In some cases, without use style rules, it may be a very poor design experience. So, yes, these users need customization. Okay, but what would be the solutions, in this scenario? Considering the different ways to insert CSS in a html page, I suppose these solutions:

1st option: ask your sysadm

Ask to your system adm for including some CSS rules at the system's stylesheets. This will be an external or internal CSS solution. As already said, it might be not possible.

2nd option: <link> on <body>

Use external style sheet on the body tag, i.e., use of the link tag inside the area you have access (that will be, on the site, inside the body tag and not in the head tag). Some sources says this is okay, but "not a good practice", like MDN:

A <link> element can occur either in the <head> or <body> element, depending on whether it has a link type that is body-ok. For example, the stylesheet link type is body-ok, and therefore <link rel="stylesheet"> is permitted in the body. However, this isn't a good practice to follow; it makes more sense to separate your <link> elements from your body content, putting them in the <head>.

Some others, restrict it to the <head> section, like w3schools:

Note: This element goes only in the head section, but it can appear any number of times.

Testing

I tested it here (desktop environment, on a browser) and it works for me. Create a file foo.html:

<!DOCTYPE html>
<html>
<head></head>
<body>
    <link href="bar.css" type="text/css" rel="stylesheet">
    <h1 class="test1">Hello</h1>
    <h1 class="test2">World</h1>
</body>
</html>

And then a CSS file, at the same directory, called bar.css:

.test1 { 
    color: green;
};

Well, this will just looks possible if you have how upload an CSS file somewhere at the institution system. Maybe this would be the case.

3rd option: <style> on <body>

Use internet style sheet on the body tag, i.e., use of the style tag inside the area you have access (that will be, on the site, inside the body tag and not in the head tag). This is what Charles Salvia's and Sz's answers here are about. Choosing this option, consider their concerns.

4th, 5th and 6th options: JS ways

Alert These ones are related to modifying the <head> element of the page. Maybe this will not be allowed by the institution's system administrators. So, it's recommended to ask them permission first.

Okay, supposing permission granted, the strategy is access the <head>. How? JavaScript methods.

4th option: new <link> on <head>

This is another version of the 2nd option. Use external style sheet on the <head> tag, i.e., use of the <link> element outside the area you have access (that will be, on the site, not inside the body tag and yes inside the head tag). This solution complies with the recommendations of MDN and w3schools, as cited above, on 2nd option solution. A new Link object will be created.

To solve the matter through JS, there are many ways but at the following codelines I demonstrate one simple.

Testing

I tested it here (desktop environment, on a browser) and it works for me. Create a file f.html:

<!DOCTYPE html>
<html>
<head></head>
<body>
    <h1 class="test1">Hello</h1>
    <h1 class="test2">World</h1>
    <script>
        // JS code here
    </script>
</body>
</html>

Inside the script tag:

var newLink = document.createElement("link");
newLink.href = "bar.css";
newLink.rel = "stylesheet";
newLink.type = "text/css";
document.getElementsByTagName("head")[0].appendChild(newLink);

And then at the CSS file, at the same directory, called bar.css (as at the 2nd option):

.test1 { 
    color: green;
};

As I already said: this will just looks possible if you have how upload an CSS file somewhere at the institution system.

5th option: new <style> on <head>

Use new internal style sheet on the <head> tag, i.e., use of a new <style> element outside the area you have access (that will be, on the site, not inside the body tag and yes inside the head tag). A new Style object will be created.

This is solved through JS. One simple way is demonstrated following.

Testing

I tested it here (desktop environment, on a browser) and it works for me. Create a file foobar.html:

<!DOCTYPE html>
<html>
<head></head>
<body>
    <h1 class="test1">Hello</h1>
    <h1 class="test2">World</h1>
    <script>
        // JS code here
    </script>
</body>
</html>

Inside the script tag:

var newStyle = document.createElement("style");
newStyle.innerHTML = 
    "h1.test1 {"+
        "color: green;"+
    "}";
document.getElementsByTagName("head")[0].appendChild(newStyle);

6th option: using an existing <style> on <head>

Use an existing internal style sheet on the <head> tag, i.e., use of a <style> element outside the area you have access (that will be, on the site, not inside the body tag and yes inside the head tag), if some exists. A new Style object will be created or a CSSStyleSheet object will be used (in the code of the solution adopted here).

This is at some point of view risky. First, because it may not exists some <style> object. Depending of the way you implement this solution, you may get undefined return (the system may use external style sheet). Second, because you will be editing the system design author's work (authorship issues). Third, because it may not be allowed at your institution's IT politics of safety. So, do ask permission to do this (as at in other JS solutions).

Supposing, again, permission was granted:

You will need to consider some restrictions of the method available to this way: insertRule(). The solution proposed uses the default scenario, and a operation at the first stylesheet, if some exists.

Testing

I tested it here (desktop environment, on a browser) and it works for me. Create a file foo_bar.html:

<!DOCTYPE html>
<html>
  <head></head>
  <body>
    <h1 class="test1">Hello</h1>
    <h1 class="test2">World</h1>
    <script>
      // JS code here
    </script>
  </body>
</html>

Inside the script tag:

function demoLoop(){ // remove this line
    var elmnt = document.getElementsByTagName("style");
    if (elmnt.length === 0) {
        // there isn't style objects, so it's more interesting create one
        var newStyle = document.createElement("style");
        newStyle.innerHTML =
            "h1.test1 {" +
                "color: green;" +
            "}";
        document.getElementsByTagName("head")[0].appendChild(newStyle);
    } else {
        // Using CSSStyleSheet interface
        var firstCSS = document.styleSheets[0];
        firstCSS.insertRule("h1.test2{color:blue;}"); // at this way (without index specified), will be like an Array unshift() method
    }
} // remove this too
demoLoop(); // remove this too
demoLoop(); // remove this too

Another approach to this solution it's using CSSStyleDeclaration object (docs at w3schools and MDN). But it may not be interesting, considering the risk to override existing rules on the system's CSS.

7th option: inline CSS

Use inline CSS. This solve the problem, although depending of the page size (in code lines), the maintenance (by the author itself or other assigned person) of code can be very difficult.

But depending of the context of your role at the institution, or its web system security policies, this might be the unique available solution to you.

Testing

Create a file _foobar.html:

<!DOCTYPE html>
<html>
  <head></head>
  <body>
    <h1 style="color: green;">Hello</h1>
    <h1 style="color: blue;">World</h1>    
  </body>
</html>

Answering strictly the question asked by Gagan

How is a browser supposed to render css which is non contiguous?

1. Is it supposed to generate some data structure using all the css styles on a page and use that for rendering?
2. Or does it render using style information in the order it sees?

(quote adapted)

For a more accurate answer, I suggest Google these articles:

• How Browsers Work: Behind the scenes of modern web browsers
• Render-tree Construction, Layout, and Paint
• What Does It Mean To “Render” a Webpage?
• How browser rendering works — behind the scenes
• Rendering - HTML Standard
• 10 Rendering — HTML5

Basic rule says that :

For Entities with generated identifier :

save() : It returns an entity's identifier immediately in addition to making the object persistent. So an insert query is fired immediately.

persist() : It returns the persistent object. It does not have any compulsion of returning the identifier immediately so it does not guarantee that insert will be fired immediately. It may fire an insert immediately but it is not guaranteed. In some cases, the query may be fired immediately while in others it may be fired at session flush time.

For Entities with assigned identifier :

save(): It returns an entity's identifier immediately. Since the identifier is already assigned to entity before calling save, so insert is not fired immediately. It is fired at session flush time.

persist() : same as save. It also fire insert at flush time.

Suppose we have an entity which uses a generated identifier as follows :

@Entity
@Table(name="USER_DETAILS")
public class UserDetails {
    @Id
    @Column(name = "USER_ID")
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int userId;

    @Column(name = "USER_NAME")
    private String userName;

    public int getUserId() {
        return userId;
    }
    public void setUserId(int userId) {
        this.userId = userId;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
}

save() :

    Session session = sessionFactory.openSession();
    session.beginTransaction();
    UserDetails user = new UserDetails();
    user.setUserName("Gaurav");
    session.save(user); // Query is fired immediately as this statement is executed.
    session.getTransaction().commit();
    session.close();

persist() :

    Session session = sessionFactory.openSession();
    session.beginTransaction();
    UserDetails user = new UserDetails();
    user.setUserName("Gaurav");
    session.persist(user); // Query is not guaranteed to be fired immediately. It may get fired here.
    session.getTransaction().commit(); // If it not executed in last statement then It is fired here.
    session.close();

Now suppose we have the same entity defined as follows without the id field having generated annotation i.e. ID will be assigned manually.

@Entity
@Table(name="USER_DETAILS")
public class UserDetails {
    @Id
    @Column(name = "USER_ID")
    private int userId;

    @Column(name = "USER_NAME")
    private String userName;

    public int getUserId() {
        return userId;
    }
    public void setUserId(int userId) {
        this.userId = userId;
    }
    public String getUserName() {
        return userName;
    }
    public void setUserName(String userName) {
        this.userName = userName;
    }
}

for save() :

Session session = sessionFactory.openSession();
session.beginTransaction();
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("Gaurav");
session.save(user); // Query is not fired here since id for object being referred by user is already available. No query need to be fired to find it. Data for user now available in first level cache but not in db.
session.getTransaction().commit();// Query will be fired at this point and data for user will now also be available in DB
session.close();

for persist() :

Session session = sessionFactory.openSession();
session.beginTransaction();
UserDetails user = new UserDetails();
user.setUserId(1);
user.setUserName("Gaurav");
session.persist(user); // Query is not fired here.Object is made persistent. Data for user now available in first level cache but not in db.
session.getTransaction().commit();// Query will be fired at this point and data for user will now also be available in DB
session.close();

The above cases were true when the save or persist were called from within a transaction.

The other points of difference between save and persist are :

1. save() can be called outside a transaction. If assigned identifier is used then since id is already available, so no insert query is immediately fired. The query is only fired when the session is flushed.

2. If generated identifier is used , then since id need to generated, insert is immediately fired. But it only saves the primary entity. If the entity has some cascaded entities then those will not be saved in db at this point. They will be saved when the session is flushed.

3. If persist() is outside a transaction then insert is fired only when session is flushed no matter what kind of identifier (generated or assigned) is used.

4. If save is called over a persistent object, then the entity is saved using update query.

To pass the function as parameter, simply remove the brackets!

function ToBeCalled(){
  alert("I was called");
}

function iNeedParameter( paramFunc) {
   //it is a good idea to check if the parameter is actually not null
   //and that it is a function
   if (paramFunc && (typeof paramFunc == "function")) {
      paramFunc();   
   }
}

//this calls iNeedParameter and sends the other function to it
iNeedParameter(ToBeCalled); 

The idea behind this is that a function is quite similar to a variable. Instead of writing

function ToBeCalled() { /* something */ }

you might as well write

var ToBeCalledVariable = function () { /* something */ }

There are minor differences between the two, but anyway - both of them are valid ways to define a function. Now, if you define a function and explicitly assign it to a variable, it seems quite logical, that you can pass it as parameter to another function, and you don't need brackets:

anotherFunction(ToBeCalledVariable);

Look at module fnmatch. That will do what you're trying to do.

import fnmatch
import os

for file in os.listdir('.'):
    if fnmatch.fnmatch(file, '*.txt'):
        print file

It also happens if you're trying to access an instance when you have a pointer, and vice versa:

struct foo
{
  int x, y, z;
};

struct foo a, *b = &a;

b.x = 12;  /* This will generate the error, should be b->x or (*b).x */

As pointed out in a comment, this can be made excruciating if someone goes and typedefs a pointer, i.e. includes the * in a typedef, like so:

typedef struct foo* Foo;

Because then you get code that looks like it's dealing with instances, when in fact it's dealing with pointers:

Foo a_foo = get_a_brand_new_foo();
a_foo->field = FANTASTIC_VALUE;

Note how the above looks as if it should be written a_foo.field, but that would fail since Foo is a pointer to struct. I strongly recommend against typedef:ed pointers in C. Pointers are important, don't hide your asterisks. Let them shine.

It depends on which version of Oracle? Older versions require exp (export), newer versions use expdp (data pump); exp was deprecated but still works most of the time.

Before starting, note that Data Pump exports to the server-side Oracle "directory", which is an Oracle symbolic location mapped in the database to a physical location. There may be a default directory (DATA_PUMP_DIR), check by querying DBA_DIRECTORIES:

  SQL> select * from dba_directories;

... and if not, create one

  SQL> create directory DATA_PUMP_DIR as '/oracle/dumps';
  SQL> grant all on directory DATA_PUMP_DIR to myuser;    -- DBAs dont need this grant

Assuming you can connect as the SYSTEM user, or another DBA, you can export any schema like so, to the default directory:

 $ expdp system/manager schemas=user1 dumpfile=user1.dpdmp

Or specifying a specific directory, add directory=<directory name>:

 C:\> expdp system/manager schemas=user1 dumpfile=user1.dpdmp directory=DUMPDIR

With older export utility, you can export to your working directory, and even on a client machine that is remote from the server, using:

 $ exp system/manager owner=user1 file=user1.dmp

Make sure the export is done in the correct charset. If you haven't setup your environment, the Oracle client charset may not match the DB charset, and Oracle will do charset conversion, which may not be what you want. You'll see a warning, if so, then you'll want to repeat the export after setting NLS_LANG environment variable so the client charset matches the database charset. This will cause Oracle to skip charset conversion.

Example for American UTF8 (UNIX):

 $ export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

Windows uses SET, example using Japanese UTF8:

 C:\> set NLS_LANG=Japanese_Japan.AL32UTF8

I needed something that I could use to search all my servers using CMS and search by server, DB, schema or table. This is what I found (originally posted by Michael Sorens here: How do I list all tables in all databases in SQL Server in a single result set? ).

You need to start by understanding that the target of a symlink is a pathname. And it can be absolute or relative to the directory which contains the symlink

Assuming you have foo.conf in sites-available

Try

cd sites-enabled
sudo ln -s ../sites-available/foo.conf .
ls -l

Now you will have a symlink in sites-enabled called foo.conf which has a target ../sites-available/foo.conf

Just to be clear, the normal configuration for Apache is that the config files for potential sites live in sites-available and the symlinks for the enabled sites live in sites-enabled, pointing at targets in sites-available. That doesn't quite seem to be the case the way you describe your setup, but that is not your primary problem.

If you want a symlink to ALWAYS point at the same file, regardless of the where the symlink is located, then the target should be the full path.

ln -s /etc/apache2/sites-available/foo.conf mysimlink-whatever.conf

Here is (line 1 of) the output of my ls -l /etc/apache2/sites-enabled:

lrwxrwxrwx 1 root root  26 Jun 24 21:06 000-default -> ../sites-available/default

See how the target of the symlink is relative to the directory that contains the symlink (it starts with ".." meaning go up one directory).

Hardlinks are totally different because the target of a hardlink is not a directory entry but a filing system Inode.

Just note to anyone trying the REGEXP to use "LIKE IN" functionality.

IN allows you to do:

field IN (
'val1',
'val2',
'val3'
)

In REGEXP this won't work

REGEXP '
val1$|
val2$|
val3$
'

It has to be in one line like this:

REGEXP 'val1$|val2$|val3$'

As mentioned by other folks, the variable length of the string is the issue.

Rather than reinventing the wheel, Apache Commons has a nice, clean solution for this in StringUtils.

StringUtils.rightPad("String to extend",100); //100 is the length you want to pad out to.

Had the same problem. Solution: Context menu -> Maven -> Enable dependency management

Do not know why that was lost, when checking out.

There is a specific method to do this:

$objPHPExcel->getActiveSheet()->mergeCells('A1:C1');

You can also use:

$objPHPExcel->setActiveSheetIndex(0)->mergeCells('A1:C1');

That should do the trick.

Download MSBuild with the link from @Nicodemeus answer was OK, yet the installation was broken until I've added these keys into a register:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\MSBuild\ToolsVersions\12.0]
"VCTargetsPath11"="$([MSBuild]::ValueOrDefault('$(VCTargetsPath11)','$(MSBuildExtensionsPath32)\\Microsoft.Cpp\\v4.0\\V110\\'))"
"VCTargetsPath"="$([MSBuild]::ValueOrDefault('$(VCTargetsPath)','$(MSBuildExtensionsPath32)\\Microsoft.Cpp\\v4.0\\V110\\'))" 

Make the left and right margins of your UL auto and assign it a width:

#headermenu ul {
    margin: 0 auto;
    width: 620px;
}

Edit: As kleinfreund has suggested, you can also center align the container and give the ul an inline-block display, but you then also have to give the LIs either a left float or an inline display.

#headermenu { 
    text-align: center;
}
#headermenu ul { 
    display: inline-block;
}
#headermenu ul li {
    float: left; /* or display: inline; */
}

dataGridView1.AutoResizeColumns();

The following seems pretty natural to me, using Haskell. Iterate recursively over levels of the tree (here I collect names into a big ordered string to show the path through the tree):

data Node = Node {name :: String, children :: [Node]}
aTree = Node "r" [Node "c1" [Node "gc1" [Node "ggc1" []], Node "gc2" []] , Node "c2" [Node "gc3" []], Node "c3" [] ]
breadthFirstOrder x = levelRecurser [x]
    where levelRecurser level = if length level == 0
                                then ""
                                else concat [name node ++ " " | node <- level] ++ levelRecurser (concat [children node | node <- level])

Go to the file C:\wamp\apps\phpmyadmin3.2.0.1\config.inc.php

Find the line $cfg['Servers'][$i]['password']='' and change it to

$cfg['Servers'][$i]['password']='root'

where root is the name of the password you had set in this instance

Hope this helps somebody.

hope it's worked for you:

File yourFile = new File(Environment.getExternalStorageDirectory(), "textarabics.txt");

This will give u sdcard path:

File path = Environment.getExternalStorageDirectory();

Try this:

String pathName = "/mnt/";

or try this:

String pathName = "/storage/";

This could help if you wish to get directory contents as an array, ignoring hidden files and directories.

function dir_tree($dir_path)
{
    $rdi = new \RecursiveDirectoryIterator($dir_path);

    $rii = new \RecursiveIteratorIterator($rdi);

    $tree = [];

    foreach ($rii as $splFileInfo) {
        $file_name = $splFileInfo->getFilename();

        // Skip hidden files and directories.
        if ($file_name[0] === '.') {
            continue;
        }

        $path = $splFileInfo->isDir() ? array($file_name => array()) : array($file_name);

        for ($depth = $rii->getDepth() - 1; $depth >= 0; $depth--) {
            $path = array($rii->getSubIterator($depth)->current()->getFilename() => $path);
        }

        $tree = array_merge_recursive($tree, $path);
    }

    return $tree;
}

The result would be something like;

dir_tree(__DIR__.'/public');

[
    'css' => [
        'style.css',
        'style.min.css',
    ],
    'js' => [
        'script.js',
        'script.min.js',
    ],
    'favicon.ico',
]

Do you need the cursor to be a "wait" cursor only when it's over that particular page/usercontrol? If not, I'd suggest using Mouse.OverrideCursor:

Mouse.OverrideCursor = Cursors.Wait;
try
{
    // do stuff
}
finally
{
    Mouse.OverrideCursor = null;
}

This overrides the cursor for your application rather than just for a part of its UI, so the problem you're describing goes away.

Here is the official FAQ on installing Python Modules: http://docs.python.org/install/index.html

There are some tips which might help you.

As of Python 3.4, the hashlib module in the standard library contains key derivation functions which are "designed for secure password hashing".

So use one of those, like hashlib.pbkdf2_hmac, with a salt generated using os.urandom:

from typing import Tuple
import os
import hashlib
import hmac

def hash_new_password(password: str) -> Tuple[bytes, bytes]:
    """
    Hash the provided password with a randomly-generated salt and return the
    salt and hash to store in the database.
    """
    salt = os.urandom(16)
    pw_hash = hashlib.pbkdf2_hmac('sha256', password.encode(), salt, 100000)
    return salt, pw_hash

def is_correct_password(salt: bytes, pw_hash: bytes, password: str) -> bool:
    """
    Given a previously-stored salt and hash, and a password provided by a user
    trying to log in, check whether the password is correct.
    """
    return hmac.compare_digest(
        pw_hash,
        hashlib.pbkdf2_hmac('sha256', password.encode(), salt, 100000)
    )

# Example usage:
salt, pw_hash = hash_new_password('correct horse battery staple')
assert is_correct_password(salt, pw_hash, 'correct horse battery staple')
assert not is_correct_password(salt, pw_hash, 'Tr0ub4dor&3')
assert not is_correct_password(salt, pw_hash, 'rosebud')

Note that:

• The use of a 16-byte salt and 100000 iterations of PBKDF2 match the minimum numbers recommended in the Python docs. Further increasing the number of iterations will make your hashes slower to compute, and therefore more secure.
• os.urandom always uses a cryptographically secure source of randomness
• hmac.compare_digest, used in is_correct_password, is basically just the == operator for strings but without the ability to short-circuit, which makes it immune to timing attacks. That probably doesn't really provide any extra security value, but it doesn't hurt, either, so I've gone ahead and used it.

For theory on what makes a good password hash and a list of other functions appropriate for hashing passwords with, see https://security.stackexchange.com/q/211/29805.

No, there is no such possibility. Allthough, one could imagine:

public static boolean contains(String s, Collection<String>c) {
    for (String ss : c) {
       if (s.equalsIgnoreCase(ss)) return true;
    }
    return false;
}

You will need to melt your dataframe to get it into the so-called long format:

require(reshape2)
sample.data.M <- melt(sample.data)

Now your field values are represented by their own rows and identified through the variable column. This can now be leveraged within the ggplot aesthetics:

require(ggplot2)
c <- ggplot(sample.data.M, aes(x = Rank, y = value, fill = variable))
c + geom_bar(stat = "identity")

Instead of stacking you may also be interested in showing multiple plots using facets:

c <- ggplot(sample.data.M, aes(x = Rank, y = value))
c + facet_wrap(~ variable) + geom_bar(stat = "identity")

Well for a cache you will generally be looking up some piece of data via a proxy object, (a URL, String....) so interface-wise you are going to want a map. but to kick things out you want a queue like structure. Internally I would maintain two data structures, a Priority-Queue and a HashMap. heres an implementation that should be able to do everything in O(1) time.

Here's a class I whipped up pretty quick:

import java.util.HashMap;
import java.util.Map;
public class LRUCache<K, V>
{
    int maxSize;
    int currentSize = 0;

    Map<K, ValueHolder<K, V>> map;
    LinkedList<K> queue;

    public LRUCache(int maxSize)
    {
        this.maxSize = maxSize;
        map = new HashMap<K, ValueHolder<K, V>>();
        queue = new LinkedList<K>();
    }

    private void freeSpace()
    {
        K k = queue.remove();
        map.remove(k);
        currentSize--;
    }

    public void put(K key, V val)
    {
        while(currentSize >= maxSize)
        {
            freeSpace();
        }
        if(map.containsKey(key))
        {//just heat up that item
            get(key);
            return;
        }
        ListNode<K> ln = queue.add(key);
        ValueHolder<K, V> rv = new ValueHolder<K, V>(val, ln);
        map.put(key, rv);       
        currentSize++;
    }

    public V get(K key)
    {
        ValueHolder<K, V> rv = map.get(key);
        if(rv == null) return null;
        queue.remove(rv.queueLocation);
        rv.queueLocation = queue.add(key);//this ensures that each item has only one copy of the key in the queue
        return rv.value;
    }
}

class ListNode<K>
{
    ListNode<K> prev;
    ListNode<K> next;
    K value;
    public ListNode(K v)
    {
        value = v;
        prev = null;
        next = null;
    }
}

class ValueHolder<K,V>
{
    V value;
    ListNode<K> queueLocation;
    public ValueHolder(V value, ListNode<K> ql)
    {
        this.value = value;
        this.queueLocation = ql;
    }
}

class LinkedList<K>
{
    ListNode<K> head = null;
    ListNode<K> tail = null;

    public ListNode<K> add(K v)
    {
        if(head == null)
        {
            assert(tail == null);
            head = tail = new ListNode<K>(v);
        }
        else
        {
            tail.next = new ListNode<K>(v);
            tail.next.prev = tail;
            tail = tail.next;
            if(tail.prev == null)
            {
                tail.prev = head;
                head.next = tail;
            }
        }
        return tail;
    }

    public K remove()
    {
        if(head == null)
            return null;
        K val = head.value;
        if(head.next == null)
        {
            head = null;
            tail = null;
        }
        else
        {
            head = head.next;
            head.prev = null;
        }
        return val;
    }

    public void remove(ListNode<K> ln)
    {
        ListNode<K> prev = ln.prev;
        ListNode<K> next = ln.next;
        if(prev == null)
        {
            head = next;
        }
        else
        {
            prev.next = next;
        }
        if(next == null)
        {
            tail = prev;
        }
        else
        {
            next.prev = prev;
        }       
    }
}

Here's how it works. Keys are stored in a linked list with the oldest keys in the front of the list (new keys go to the back) so when you need to 'eject' something you just pop it off the front of the queue and then use the key to remove the value from the map. When an item gets referenced you grab the ValueHolder from the map and then use the queuelocation variable to remove the key from its current location in the queue and then put it at the back of the queue (its now the most recently used). Adding things is pretty much the same.

I'm sure theres a ton of errors here and I haven't implemented any synchronization. but this class will provide O(1) adding to the cache, O(1) removal of old items, and O(1) retrieval of cache items. Even a trivial synchronization (just synchronize every public method) would still have little lock contention due to the run time. If anyone has any clever synchronization tricks I would be very interested. Also, I'm sure there are some additional optimizations that you could implement using the maxsize variable with respect to the map.

hack but works - (tested on chrome and mobile)

just add no break spaces   till it breaks - you might have to limit the tooltip size depending on the amount of content but for small text messages this works:

   etc

Tried everything above and this is the only thing that worked for me -

What about a little trickery like NgModel does with NgForm? You have to register your parent as a provider, then load your parent in the constructor of the child.

That way, you don't have to put [sharedList] on all your children.

// Parent.ts
export var parentProvider = {
    provide: Parent,
    useExisting: forwardRef(function () { return Parent; })
};

@Component({
    moduleId: module.id,
    selector: 'parent',
    template: '<div><ng-content></ng-content></div>',
    providers: [parentProvider]
})
export class Parent {
    @Input()
    public sharedList = [];
}

// Child.ts
@Component({
    moduleId: module.id,
    selector: 'child',
    template: '<div>child</div>'
})
export class Child {
    constructor(private parent: Parent) {
        parent.sharedList.push('Me.');
    }
}

Then your HTML

<parent [sharedList]="myArray">
    <child></child>
    <child></child>
</parent>

I'm developing cordova apps for 2 years and I spent weeks to solve related problems (eg: webview scrolls when keyboard open). Here's a tested and proven solution for both ios and android

P.S.: I'm using iScroll for scrolling content

1. Never use viewport-fit=cover at index.html's meta tag, leave the app stay out of statusbar. iOS will handle proper area for all iPhone variants.
2. In XCode uncheck hide status bar and requires full screen and don't forget to select Launch Screen File as CDVLaunchScreen
3. In config.xml set fullscreen as false
4. Finally, (thanks to Eddy Verbruggen for great plugins) add his plugin cordova-plugin-webviewcolor to set statusbar and bottom area background color. This plugin will allow you to set any color you want.

5. Add below to config.xml (first ff after x is opacity)

   <preference name="BackgroundColor" value="0xff088c90" />
   

6. Handle your scroll position yourself by adding focus events to input elements

   iscrollObj.scrollToElement(elm, transitionduration ... etc)
   

For android, do the same but instead of cordova-plugin-webviewcolor, install cordova-plugin-statusbar and cordova-plugin-navigationbar-color

Here's a javascript code using those plugins to work on both ios and android:

function setStatusColor(colorCode) {
    //colorCode is smtg like '#427309';
    if (cordova.platformId == 'android') {
        StatusBar.backgroundColorByHexString(colorCode);
        NavigationBar.backgroundColorByHexString(colorCode);
    } else if (cordova.platformId == 'ios') {
        window.plugins.webviewcolor.change(colorCode);
    }
}

Microsoft has a tool just for this purpose: Microsoft Expression Web. There's a free version with a bunch of FrontPage/Dreamweaver-like garbage that nobody wants. What's important is that it has a great browser testing feature. I'm running Windows 8.1 Pro (final release, not preview) with Internet Explorer 11. I get these local browsers:

• Internet Explorer 6
• Internet Explorer 7
• Internet Explorer 11 /!\ Unsupported Version (can't use it; big whoop, I have the browser)

Then I get a Remote Browsers (Beta) option. I'm supposed to sign up with a valid e-mail, but there's an error communicating with the server. Oh well.

Firefox used to be supported, but I don't see it now. Might be hiding.

I can compare side-by-side between browser versions. I can also compare with an image, or apparently, a PSD file (no idea how well that works). InDesign would be nice, but that's probably asking for too much.

I have the full version of Expression partially installed as well due to Visual Studio Ultimate being on the same computer, so I'd appreciate someone confirming in a comment that my free installation isn't automatically upgrading.

Update: Looks like the online service was discontinued, but local browsers are still supported. You can also download just SuperPreview, without the editor garbage. If you want the full IDE, the latest version is Microsoft Expression Web 4 (Free Version). Here's the official list of supported browsers. IE6 seems to give an error on Windows 8.1, but IE7 works.

Update 2014-12-09: Microsoft has pretty much given up on this. Don't expect it to work well.

#include <string>
#include <locale>

std::string str = "Hello World!";
auto & f = std::use_facet<std::ctype<char>>(std::locale());
f.toupper(str.data(), str.data() + str.size());

This will perform better than all the answers that use the global toupper function, and is presumably what boost::to_upper is doing underneath.

This is because ::toupper has to look up the locale - because it might've been changed by a different thread - for every invocation, whereas here only the call to locale() has this penalty. And looking up the locale generally involves taking a lock.

This also works with C++98 after you replace the auto, use of the new non-const str.data(), and add a space to break the template closing (">>" to "> >") like this:

std::use_facet<std::ctype<char> > & f = 
    std::use_facet<std::ctype<char> >(std::locale());
f.toupper(const_cast<char *>(str.data()), str.data() + str.size());

If you are using gridview and not bind gridview at pageload inside !ispostback then this error occur when you click on edit and delete row in gridview .

 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
        bindGridview();
        }
