I believe a watermark as mentioned in this post would work well in this case

There's a bit of code needed but you can reuse it for any combobox or textbox (and even passwordboxes) so I prefer this way

In later versions, the plugin has changed name to:

apply plugin: 'com.android.library'

And as already mentioned by some of the other answers, you need the gradle tools in order to use it. Using 3.0.1, you have to use the google repo, not mavenCentral or jcenter:

buildscript {
    repositories {
        ...
        //In IntelliJ or older versions of Android Studio
        //maven {
        //   url 'https://maven.google.com'
        //}
        google()//in newer versions of Android Studio
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
    }
}

One issue is that reindex will fail if there are duplicate values. Say we're working with timestamped data, which we want to index by date:

df = pd.DataFrame({
    'timestamps': pd.to_datetime(
        ['2016-11-15 1:00','2016-11-16 2:00','2016-11-16 3:00','2016-11-18 4:00']),
    'values':['a','b','c','d']})
df.index = pd.DatetimeIndex(df['timestamps']).floor('D')
df

yields

            timestamps             values
2016-11-15  "2016-11-15 01:00:00"  a
2016-11-16  "2016-11-16 02:00:00"  b
2016-11-16  "2016-11-16 03:00:00"  c
2016-11-18  "2016-11-18 04:00:00"  d

Due to the duplicate 2016-11-16 date, an attempt to reindex:

all_days = pd.date_range(df.index.min(), df.index.max(), freq='D')
df.reindex(all_days)

fails with:

...
ValueError: cannot reindex from a duplicate axis

(by this it means the index has duplicates, not that it is itself a dup)

Instead, we can use .loc to look up entries for all dates in range:

df.loc[all_days]

yields

            timestamps             values
2016-11-15  "2016-11-15 01:00:00"  a
2016-11-16  "2016-11-16 02:00:00"  b
2016-11-16  "2016-11-16 03:00:00"  c
2016-11-17  NaN                    NaN
2016-11-18  "2016-11-18 04:00:00"  d

fillna can be used on the column series to fill blanks if needed.

You can create an std::string

#include <string>
#include <vector>
int main(int argc, char *argv[])
{
  // check if there is more than one argument and use the second one
  //  (the first argument is the executable)
  if (argc > 1)
  {
    std::string arg1(argv[1]);
    // do stuff with arg1
  }

  // Or, copy all arguments into a container of strings
  std::vector<std::string> allArgs(argv, argv + argc);
}

Look at the ToLookup and/or ToDictionary extension methods.

I tend to use this method

$errorlevel=error_reporting();
$errorlevel=error_reporting($errorlevel & ~E_DEPRECATED);

In this way I do not turn off accidentally something I need

The pointsize command scales the size of points, but does not affect the size of dots.

In other words, plot ... with points ps 2 will generate points of twice the normal size, but for plot ... with dots ps 2 the "ps 2" part is ignored.

You could use circular points (pt 7), which look just like dots.

No, they are pretty different from each other.

Both are different specializations of @Component annotation (in practice, they're two different implementations of the same interface) so both can be discovered by the classpath scanning (if you declare it in your XML configuration)

@Service annotation is used in your service layer and annotates classes that perform service tasks, often you don't use it but in many case you use this annotation to represent a best practice. For example, you could directly call a DAO class to persist an object to your database but this is horrible. It is pretty good to call a service class that calls a DAO. This is a good thing to perform the separation of concerns pattern.

@Controller annotation is an annotation used in Spring MVC framework (the component of Spring Framework used to implement Web Application). The @Controller annotation indicates that a particular class serves the role of a controller. The @Controller annotation acts as a stereotype for the annotated class, indicating its role. The dispatcher scans such annotated classes for mapped methods and detects @RequestMapping annotations.

So looking at the Spring MVC architecture you have a DispatcherServlet class (that you declare in your XML configuration) that represent a front controller that dispatch all the HTTP Request towards the appropriate controller classes (annotated by @Controller). This class perform the business logic (and can call the services) by its method. These classes (or its methods) are typically annotated also with @RequestMapping annotation that specify what HTTP Request is handled by the controller and by its method.

For example:

@Controller
@RequestMapping("/appointments")
public class AppointmentsController {

    private final AppointmentBook appointmentBook;

    @Autowired
    public AppointmentsController(AppointmentBook appointmentBook) {
        this.appointmentBook = appointmentBook;
    }

    @RequestMapping(method = RequestMethod.GET)
    public Map<String, Appointment> get() {
        return appointmentBook.getAppointmentsForToday();
    }

This class is a controller.

This class handles all the HTTP Request toward "/appointments" "folder" and in particular the get method is the method called to handle all the GET HTTP Request toward the folder "/appointments".

I hope that now it is more clear for you.

This may or may not be helpful but on Windows you can read the console log using Event Tracing for Windows

http://msdn.microsoft.com/en-us/library/ms751538.aspx

Our integration tests are run in .NET so I use this method to add the console log to our test output. I've made a sample console project to demonstrate here: https://github.com/jkells/chrome-trace

--enable-logging --v=1 doesn't seem to work on the latest version of Chrome.

Remember that Constructor of an object is called immediately after the memory is allocated for that object and whereas the destructor is called just before deallocating the memory of that object.

What @JosephSilber said, or pass the $event object into ng-click callback and stop the propagation inside of it:

<div ng-controller="OverlayCtrl" class="overlay" ng-click="hideOverlay()">
  <img src="http://some_src" ng-click="nextImage($event)"/>
</div>

$scope.nextImage = function($event) {
  $event.stopPropagation();
  // Some code to find and display the next image
}

db.users.count()
db.users.remove({})
db.users.count()

To write text to (or read text from) the Windows clipboard use this VBA function:

Function Clipboard$(Optional s$)
    Dim v: v = s  'Cast to variant for 64-bit VBA support
    With CreateObject("htmlfile")
    With .parentWindow.clipboardData
        Select Case True
            Case Len(s): .setData "text", v
            Case Else:   Clipboard = .getData("text")
        End Select
    End With
    End With
End Function

'Three examples of copying text to the clipboard:
Clipboard "Excel Hero was here."
Clipboard var1 & vbLF & var2
Clipboard 123

'To read text from the clipboard:
MsgBox Clipboard

This is a solution that does NOT use MS Forms nor the Win32 API. Instead it uses the Microsoft HTML Object Library which is fast and ubiquitous and NOT deprecated by Microsoft like MS Forms. And this solution respects line feeds. This solution also works from 64-bit Office. Finally, this solution allows both writing to and reading from the Windows clipboard. No other solution on this page has these benefits.

SQL Server(2012) provides another way to generate script for the SQL Server databases with its objects and data. This script can be used to copy the tables’ schema and data from the source database to the destination one in our case.

1. Using the SQL Server Management Studio, right-click on the source database from the object explorer, then from Tasks choose Generate Scripts.
2. In the Choose objects window, choose Select Specific Database Objects to specify the tables that you will generate script for, then choose the tables by ticking beside each one of it. Click Next.
3. In the Set Scripting Options window, specify the path where you will save the generated script file, and click Advanced.
4. From the appeared Advanced Scripting Options window, specify Schema and Data as Types of Data to Script. You can decide from here if you want to script the indexes and keys in your tables. Click OK. Getting back to the Advanced Scripting Options window, click Next.
5. Review the Summary window and click Next.
6. You can monitor the progress from the Save or Publish Scripts window. If there is no error click Finish and you will find the script file in the specified path.

SQL Scripting method is useful to generate one single script for the tables’ schema and data, including the indexes and keys. But again this method doesn’t generate the tables’ creation script in the correct order if there are relations between the tables.

Laravel is not actually that slow. 500-1000ms is absurd; I got it down to 20ms in debug mode.

The problem was Vagrant/VirtualBox + shared folders. I didn't realize they incurred such a performance hit. I guess because Laravel has so many dependencies (loads ~280 files) and each of those file reads is slow, it adds up really quick.

kreeves pointed me in the right direction, this blog post describes a new feature in Vagrant 1.5 that lets you rsync your files into the VM rather than using a shared folder.

There's no native rsync client on Windows, so you'll have to use cygwin. Install it, and make sure to check off Net/rsync. Add C:\cygwin64\bin to your paths. [Or you can install it on Win10/Bash]

Vagrant introduces the new feature. I'm using Puphet, so my Vagrantfile looks a bit funny. I had to tweak it to look like this:

  data['vm']['synced_folder'].each do |i, folder|
    if folder['source'] != '' && folder['target'] != '' && folder['id'] != ''
      config.vm.synced_folder "#{folder['source']}", "#{folder['target']}", 
        id: "#{folder['id']}", 
        type: "rsync",
        rsync__auto: "true",
        rsync__exclude: ".hg/"
    end
  end

Once you're all set up, try vagrant up. If everything goes smoothly your machine should boot up and it should copy all the files over. You'll need to run vagrant rsync-auto in a terminal to keep the files up to date. You'll pay a little bit in latency, but for 30x faster page loads, it's worth it!

If you're using PhpStorm, it's auto-upload feature works even better than rsync. PhpStorm creates a lot of temporary files which can trip up file watchers, but if you let it handle the uploads itself, it works nicely.

One more option is to use lsyncd. I've had great success using this on Ubuntu host -> FreeBSD guest. I haven't tried it on a Windows host yet.

Thanks Pablo, just what I was looking for! However, if I can take the liberty of improving your script slightly, I suggest replacing your ^V macro with the following:

; Use backslash instead of backtick (yes, I am a C++ programmer).
#EscapeChar \

; Paste in command window.
^V::
StringReplace clipboard2, clipboard, \r\n, \n, All
SendInput {Raw}%clipboard2%
return

The advantage of using SendInput is that

• it doesn't rely on the command prompt system menu having an "Alt+Space E P" menu item to do the pasting (works for English and Spanish, but not for all languages).
• it avoids that nasty flicker you get as the menu is created and destroyed.

Note, it's important to include the "{Raw}" in the SendInput command, in case the clipboard happens to contain "!", "+", "^" or "#".

Note, it uses StringReplace to remove excess Windows carriage return characters. Thanks hugov for that suggestion!

I wrote a function to accomplish this, because the others ways weren't working for me.

public string getEndDate (DateTime startDate,decimal monthCount)
{
    int y = startDate.Year;
    int m = startDate.Month;

    for (decimal  i = monthCount; i > 1; i--)
    {
        m++;
        if (m == 12)
        { y++;
            m = 1;
        }
    }
    return string.Format("{0}-{1}-{2}", y.ToString(), m.ToString(), startDate.Day.ToString());
}

In Cygwin:

$cmp -bl <file1> <file2>

diffs binary offsets and values are in decimal and octal respectively.. Vladi.

The way using a Swift Extension to UIImageView (source code here):

Creating Computed Property for Associated UIActivityIndicatorView

import Foundation
import UIKit
import ObjectiveC

private var activityIndicatorAssociationKey: UInt8 = 0

extension UIImageView {
    //Associated Object as Computed Property
    var activityIndicator: UIActivityIndicatorView! {
        get {
            return objc_getAssociatedObject(self, &activityIndicatorAssociationKey) as? UIActivityIndicatorView
        }
        set(newValue) {
            objc_setAssociatedObject(self, &activityIndicatorAssociationKey, newValue, UInt(OBJC_ASSOCIATION_RETAIN))
        }
    }

    private func ensureActivityIndicatorIsAnimating() {
        if (self.activityIndicator == nil) {
            self.activityIndicator = UIActivityIndicatorView(activityIndicatorStyle: UIActivityIndicatorViewStyle.Gray)
            self.activityIndicator.hidesWhenStopped = true
            let size = self.frame.size;
            self.activityIndicator.center = CGPoint(x: size.width/2, y: size.height/2);
            NSOperationQueue.mainQueue().addOperationWithBlock({ () -> Void in
                self.addSubview(self.activityIndicator)
                self.activityIndicator.startAnimating()
            })
        }
    }

Custom Initializer and Setter

    convenience init(URL: NSURL, errorImage: UIImage? = nil) {
        self.init()
        self.setImageFromURL(URL)
    }

    func setImageFromURL(URL: NSURL, errorImage: UIImage? = nil) {
        self.ensureActivityIndicatorIsAnimating()
        let downloadTask = NSURLSession.sharedSession().dataTaskWithURL(URL) {(data, response, error) in
            if (error == nil) {
                NSOperationQueue.mainQueue().addOperationWithBlock({ () -> Void in
                    self.activityIndicator.stopAnimating()
                    self.image = UIImage(data: data)
                })
            }
            else {
                self.image = errorImage
            }
        }
        downloadTask.resume()
    }
}

If you're using Weebly, start by viewing the published site and right-clicking the image to Copy Image Address. Then in Weebly, go to Edit Site, Pages, click the page you wish to use, SEO Settings, under Header Code enter the code from Shef's answer:

<meta property="og:image" content="/uploads/..." />

just replacing /uploads/... with the copied image address. Click Publish to apply the change.

You can skip the part of Shef's answer about namespace, because that's already set by default in Weebly.

You can use chmod with the X mode letter (the capital X) to set the executable flag only for directories.

In the example below the executable flag is cleared and then set for all directories recursively:

~$ mkdir foo
~$ mkdir foo/bar
~$ mkdir foo/baz
~$ touch foo/x
~$ touch foo/y

~$ chmod -R go-X foo 
~$ ls -l foo
total 8
drwxrw-r-- 2 wq wq 4096 Nov 14 15:31 bar
drwxrw-r-- 2 wq wq 4096 Nov 14 15:31 baz
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 x
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 y

~$ chmod -R go+X foo 
~$ ls -l foo
total 8
drwxrwxr-x 2 wq wq 4096 Nov 14 15:31 bar
drwxrwxr-x 2 wq wq 4096 Nov 14 15:31 baz
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 x
-rw-rw-r-- 1 wq wq    0 Nov 14 15:31 y

A bit of explaination:

• chmod -x foo - clear the eXecutable flag for foo
• chmod +x foo - set the eXecutable flag for foo
• chmod go+x foo - same as above, but set the flag only for Group and Other users, don't touch the User (owner) permission
• chmod go+X foo - same as above, but apply only to directories, don't touch files
• chmod -R go+X foo - same as above, but do this Recursively for all subdirectories of foo

You can create a temp table variable and insert the data into it, then insert the data into your actual table by selecting it from the temp table.

 declare @TableVar table 
 (
    firstCol varchar(50) NOT NULL,
    secondCol varchar(50) NOT NULL
 )

BULK INSERT @TableVar FROM 'PathToCSVFile' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')
GO

INSERT INTO dbo.ExistingTable
(
    firstCol,
    secondCol
)
SELECT firstCol,
       secondCol
FROM @TableVar

GO

I was receiving the same error some time back. The issue was that my XLS file contained more than 65531 records(500 thousand to be precise). I was attempting to read a range of cells.

Excel.Range rng = (Excel.Range) myExcelWorkbookObj.UsedRange.Rows[i];

The exception was thrown while trying to read the range of cells when my counter, i.e. 'i', exceeded this limit of 65531 records.

FWIW, I stumbled over this very same problem (and my boss too, so it got more intense).

The instant solution is to delete or fix your Git entries in the Windows Credential Manager. You may have a hard time finding it in your localized Windows version, but luckily you can start it from the good old Windows + R run dialog with control keymgr.dll or control /name Microsoft.CredentialManager (or rundll32.exe keymgr.dll, KRShowKeyMgr if you prefer the classic look). Or put this in a batch file for your colleagues: cmdkey /delete:git:http://your.git.server.company.com.

In Microsoft's Git Credential Manager this is a known issue that may be fixed as soon as early 2019 (so don't hold your breath).

Update (2020-09-30): GCM4W seems to be more or less abandoned (last release more than a year ago, only one commit to master since then named, I kid you not, "Recreate the scalable version of the GCM Logo"). But don't despair, with Microsoft now going Core, there is a shiny new project called GCM Core, which seems to handle password changes correctly. It can be installed standalone (should be activated automatically, otherwise activate e.g. with git config --system credential.helper manager-core) but is also included in the current Git for Windows 2.28.0. For more information about it, see this blog post.

self.class.default_make

This is a very old thread, I had a new finding today. I have created an activity, I put it in another package(by mistake). In the newly created class, eclipse was not able to resolve R.

I tried all the ways mentioned in many places but I failed to notice that I put it in a different package. After struggling for few minutes I noticed that I put it in wrong package.

If you are not keeping your Activity in the activity package, you will get this error.

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

The dot operator . does not need to be escaped inside of a character class [].

You are trying to access the struct statically with a . instead of ::, nor are its members static. Either instantiate ReducedForm:

ReducedForm rf;
rf.iSimplifiedNumerator = 5;

or change the members to static like this:

struct ReducedForm
{
    static int iSimplifiedNumerator;
    static int iSimplifiedDenominator;
};

In the latter case, you must access the members with :: instead of . I highly doubt however that the latter is what you are going for ;)

You're looking for the zip builtin function. From the docs:

>>> x = [1, 2, 3]
>>> y = [4, 5, 6]
>>> zipped = zip(x, y)
>>> zipped
[(1, 4), (2, 5), (3, 6)]

You can just use pip for installing packages, even when you are using anaconda:

pip install -U scikit-learn scipy matplotlib

This should work for installing the package.

And for Python 3.x just use pip3:

pip3 install -U scikit-learn scipy matplotlib

Using Spring Framework , you can add many attachments :

package com.mkyong.common;


import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;

import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.MailParseException;
import org.springframework.mail.SimpleMailMessage;

    private JavaMailSender mailSender;
    private SimpleMailMessage simpleMailMessage;

    public void setSimpleMailMessage(SimpleMailMessage simpleMailMessage) {
        this.simpleMailMessage = simpleMailMessage;
    }

    public void setMailSender(JavaMailSender mailSender) {
        this.mailSender = mailSender;
    }

    public void sendMail(String dear, String content) {

       MimeMessage message = mailSender.createMimeMessage();

       try{
        MimeMessageHelper helper = new MimeMessageHelper(message, true);

        helper.setFrom(simpleMailMessage.getFrom());
        helper.setTo(simpleMailMessage.getTo());
        helper.setSubject(simpleMailMessage.getSubject());
        helper.setText(String.format(
            simpleMailMessage.getText(), dear, content));

        FileSystemResource file = new FileSystemResource("/home/abdennour/Documents/cv.pdf");
        helper.addAttachment(file.getFilename(), file);

         }catch (MessagingException e) {
        throw new MailParseException(e);
         }
         mailSender.send(message);
         }
}

To know how to configure your project to deal with this code , complete reading this tutorial .

You should add namespace if you are not using it:

System.Windows.Forms.MessageBox.Show("Some text", "Some title", 
    System.Windows.Forms.MessageBoxButtons.OK, 
    System.Windows.Forms.MessageBoxIcon.Error);

Alternatively, you can add at the begining of your file:

using System.Windows.Forms

and then use (as stated in previous answers):

MessageBox.Show("Some text", "Some title", 
    MessageBoxButtons.OK, MessageBoxIcon.Error);

The most condensed version:

public String getNameFromURI(Uri uri) {
    Cursor c = getContentResolver().query(uri, null, null, null, null);
    c.moveToFirst();
    return c.getString(c.getColumnIndex(OpenableColumns.DISPLAY_NAME));
}

I'll explain it in a simple way.

Generics defined at Class level are completely separate from the generics defined at the (static) method level.

class Greet<T> {

    public static <T> void sayHello(T obj) {
        System.out.println("Hello " + obj);
    }
}

When you see the above code anywhere, please note that the T defined at the class level has nothing to do with the T defined in the static method. The following code is also completely valid and equivalent to the above code.

class Greet<T> {

    public static <E> void sayHello(E obj) {
        System.out.println("Hello " + obj);
    }
}

Why the static method needs to have its own generics separate from those of the Class?

This is because, the static method can be called without even instantiating the Class. So if the Class is not yet instantiated, we do not yet know what is T. This is the reason why the static methods needs to have its own generics.

So, whenever you are calling the static method,

Greet.sayHello("Bob");
Greet.sayHello(123);

JVM interprets it as the following.

Greet.<String>sayHello("Bob");
Greet.<Integer>sayHello(123);

Both giving the same outputs.

Hello Bob
Hello 123

This code takes advantage of SIMD instructions to improve performance.

public static bool IsPositive(int n)
{
  var v = new Vector<int>(n);
  var result = Vector.GreaterThanAll(v, Vector<int>.Zero);
  return result;
}

In 32 bit virtual address system we can have 2^32 unique address, since the page size given is 4KB = 2^12, we will need (2^32/2^12 = 2^20) entries in the page table, if each entry is 4Bytes then total size of the page table = 4 * 2^20 Bytes = 4MB

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

var foo = Array.from(Array(N), (v, i) => i + 1);

Try the following:

cv::Mat image = ...do some stuff...;

image.at<cv::Vec3b>(y,x); gives you the RGB (it might be ordered as BGR) vector of type cv::Vec3b

image.at<cv::Vec3b>(y,x)[0] = newval[0];
image.at<cv::Vec3b>(y,x)[1] = newval[1];
image.at<cv::Vec3b>(y,x)[2] = newval[2];

Many of these solutions here ignore git version tags which still means you have to track version in multiple places (bad). I approached this with the following goals:

• Derive all python version references from a tag in the git repo
• Automate git tag/push and setup.py upload steps with a single command that takes no inputs.

How it works:

1. From a make release command, the last tagged version in the git repo is found and incremented. The tag is pushed back to origin.

2. The Makefile stores the version in src/_version.py where it will be read by setup.py and also included in the release. Do not check _version.py into source control!

3. setup.py command reads the new version string from package.__version__.

Details:

Makefile

# remove optional 'v' and trailing hash "v1.0-N-HASH" -> "v1.0-N"
git_describe_ver = $(shell git describe --tags | sed -E -e 's/^v//' -e 's/(.*)-.*/\1/')
git_tag_ver      = $(shell git describe --abbrev=0)
next_patch_ver = $(shell python versionbump.py --patch $(call git_tag_ver))
next_minor_ver = $(shell python versionbump.py --minor $(call git_tag_ver))
next_major_ver = $(shell python versionbump.py --major $(call git_tag_ver))

.PHONY: ${MODULE}/_version.py
${MODULE}/_version.py:
    echo '__version__ = "$(call git_describe_ver)"' > $@

.PHONY: release
release: test lint mypy
    git tag -a $(call next_patch_ver)
    $(MAKE) ${MODULE}/_version.py
    python setup.py check sdist upload # (legacy "upload" method)
    # twine upload dist/*  (preferred method)
    git push origin master --tags

The release target always increments the 3rd version digit, but you can use the next_minor_ver or next_major_ver to increment the other digits. The commands rely on the versionbump.py script that is checked into the root of the repo

versionbump.py

"""An auto-increment tool for version strings."""

import sys

    prefix = version[0] if version[0].isalpha() else ''
    digits = version.lower().lstrip('v').split('.')

    if len(digits) > MAX_DIGITS:
        click.secho('ERROR: Too many digits', fg='red', err=True)
        sys.exit(1)

    digits = (digits + ['0'] * MAX_DIGITS)[:MAX_DIGITS]  # Extend total digits to max.
    digits[bump_idx] = str(int(digits[bump_idx]) + 1)  # Increment the desired digit.

    # Zero rightmost digits after bump position.
    for i in range(bump_idx + 1, MAX_DIGITS):
        digits[i] = '0'
    digits = digits[:max(MIN_DIGITS, bump_idx + 1)]  # Trim rightmost digits.
    click.echo(prefix + '.'.join(digits), nl=False)

This does the heavy lifting how to process and increment the version number from git.

__init__.py

The my_module/_version.py file is imported into my_module/__init__.py. Put any static install config here that you want distributed with your module.

from ._version import __version__
__author__ = ''
__email__ = ''

setup.py

The last step is to read the version info from the my_module module.

from setuptools import setup, find_packages

pkg_vars  = {}

with open("{MODULE}/_version.py") as fp:
    exec(fp.read(), pkg_vars)

setup(
    version=pkg_vars['__version__'],
    ...
    ...
)

Of course, for all of this to work you'll have to have at least one version tag in your repo to start.

git tag -a v0.0.1

Recommended as an answer:

Here's a solution using es2015 generators:

function* subsetSum(numbers, target, partial = [], partialSum = 0) {

  if(partialSum === target) yield partial

  if(partialSum >= target) return

  for(let i = 0; i < numbers.length; i++){
    const remaining = numbers.slice(i + 1)
        , n = numbers[i]

    yield* subsetSum(remaining, target, [...partial, n], partialSum + n)
  }

}

Using generators can actually be very useful because it allows you to pause script execution immediately upon finding a valid subset. This is in contrast to solutions without generators (ie lacking state) which have to iterate through every single subset of numbers

I've refined this using an extension method on the ListViewItemsCollection. In my opinion it makes the calling code more concise and also promotes more general reuse.

internal static class ListViewItemCollectionExtender
{
    internal static void AddWithTextAndSubItems(
                                   this ListView.ListViewItemCollection col, 
                                   string text, params string[] subItems)
    {
        var item = new ListViewItem(text);
        foreach (var subItem in subItems)
        {
            item.SubItems.Add(subItem);
        }
        col.Add(item);
    }
}

Calling the AddWithTextAndSubItems looks like this:

// can have many sub items as it's string array
myListViewControl.Items.AddWithTextAndSubItems("Text", "Sub Item 1", "Sub Item 2"); 

Hope this helps!

UsernamePasswordAuthenticationFilter is only used for /login, and latter filters are not?

No, UsernamePasswordAuthenticationFilter extends AbstractAuthenticationProcessingFilter, and this contains a RequestMatcher, that means you can define your own processing url, this filter only handle the RequestMatcher matches the request url, the default processing url is /login.

Later filters can still handle the request, if the UsernamePasswordAuthenticationFilter executes chain.doFilter(request, response);.

More details about core fitlers

Does the form-login namespace element auto-configure these filters?

UsernamePasswordAuthenticationFilter is created by <form-login>, these are Standard Filter Aliases and Ordering

Does every request (authenticated or not) reach FilterSecurityInterceptor for non-login url?

It depends on whether the before fitlers are successful, but FilterSecurityInterceptor is the last fitler normally.

Does configuring two http elements create two springSecurityFitlerChains?

Yes, every fitlerChain has a RequestMatcher, if the RequestMatcher matches the request, the request will be handled by the fitlers in the fitler chain.

The default RequestMatcher matches all request if you don't config the pattern, or you can config the specific url (<http pattern="/rest/**").

If you want to konw more about the fitlers, I think you can check source code in spring security. doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)

See this implementation from PEP318, implementing the singleton pattern with a decorator:

def singleton(cls):
    instances = {}
    def getinstance():
        if cls not in instances:
            instances[cls] = cls()
        return instances[cls]
    return getinstance

@singleton
class MyClass:
    ...

To split your String by comma(,) use str.split(",") and for tab use str.split("\\t")

    try {
        BufferedReader in = new BufferedReader(
                               new FileReader("G:\\RoutePPAdvant2.txt"));
        String str;

        while ((str = in.readLine())!= null) {
            String[] ar=str.split(",");
            ...
        }
        in.close();
    } catch (IOException e) {
        System.out.println("File Read Error");
    }

Just do System.out.println(e.getActionCommand()); inside actionPerformed(ActionEvent e) function. This will tell you which command is just performed.

or

if(e.getActionCommand().equals("Add")){

   System.out.println("Add button pressed");
}

In practical terms, boilerplate code is the stuff you cut-n-paste all over the place. Often it'll be things like a module header, plus some standard/required declarations (every module must declare a logger, every module must declare variables for its name and revision, etc.) On my current project, we're writing message handlers and they all have the same structure (read a message, validate it, process it) and to eliminate dependencies among the handlers we didn't want to have them all inherit from a base class, so we came up with a boilerplate skeleton. It declared all the routine variables, the standard methods, exception handling framework — all a developer had to do was add the code specific to the message being handled. It would have been quick & easy to use, but then we found out we were getting our message definitions in a spreadsheet (which used a boilerplate format), so we wound up just writing a code generator to emit 90% of the code (including the unit tests).

I've created the following script and it worked for me just fine.

#! /bin/sh
cd $(dirname $0)
DB=$1
DBUSER=$2
DBPASSWD=$3
FILE=$DB-$(date +%F).sql
mysqldump --routines "--user=${DBUSER}"  --password=$DBPASSWD $DB > $PWD/$FILE
gzip $FILE
echo Created $PWD/$FILE*

and you call the script using command line arguments.

backupdb.sh my_db dev_user dev_password

I am using jQuery to solve this problem. This is the snippet for BS 3.0.0:

$(window).resize(function () { 
    $('body').css('padding-top', parseInt($('#main-navbar').css("height"))+10);
});

$(window).load(function () { 
    $('body').css('padding-top', parseInt($('#main-navbar').css("height"))+10);        
});

I've not verified that myself but it looks like people managed to include the hidden code into Android again. They seem to be able to emulate a Mifare Classic card (iso-14443). I'll soon test this myself, it looks very interesting.

If you want to do it for a commercial/free app you'll have a hard time, your users won't like to change their kernel to support your app.

Update: There would be a simple trick to make your phone emulate a ticket:
You can get a NFC-sticker and put it in or on the phone. This way you are able to read and write it at all times and other devices can also read and write it.
It's just an idea I had, never seen that used anywhere of course ;)

How about an approach that not only allows multiple domains, but allows dynamic domains.

The use case here is with a Sharepoint app part which loads our site inside of Sharepoint via an iframe. The problem is that sharepoint has dynamic subdomains such as https://yoursite.sharepoint.com. So for IE, we need to specify ALLOW-FROM https://.sharepoint.com

Tricky business, but we can get it done knowing two facts:

1. When an iframe loads, it only validates the X-Frame-Options on the first request. Once the iframe is loaded, you can navigate within the iframe and the header isn't checked on subsequent requests.

2. Also, when an iframe is loaded, the HTTP referer is the parent iframe url.

You can leverage these two facts server side. In ruby, I'm using the following code:

  uri = URI.parse(request.referer)
  if uri.host.match(/\.sharepoint\.com$/)
    url = "https://#{uri.host}"
    response.headers['X-Frame-Options'] = "ALLOW-FROM #{url}"
  end

Here we can dynamically allow domains based upon the parent domain. In this case, we ensure that the host ends in sharepoint.com keeping our site safe from clickjacking.

I'd love to hear feedback on this approach.

The solution you are looking for is in Angular's official tutorial. In this tutorial Phones are loaded from a JSON file using Angulars $http service . In the code below we use $http.get to load a phones.json file saved in the phones directory:

var phonecatApp = angular.module('phonecatApp', []);   
phonecatApp.controller('PhoneListCtrl', function ($scope, $http) {
 $http.get('phones/phones.json').success(function(data) {
$scope.phones = data;
}); 
$scope.orderProp = 'age';
});

We then iterate over the phones:

<table>
  <tbody ng-repeat="i in phones">
    <tr><td>{{i.name}}</td><td>{{$index}}</td></tr>
    <tr ng-repeat="e in i.details">
       <td>{{$index}}</td>
       <td>{{e.foo}}</td>
       <td>{{e.bar}}</td></tr>
  </tbody>
</table>

I am using a function here in my case by which I am updating a label with the normal time format and after that I am storing the selected time's 24hr format to do some another tasks..

Here is my code...

func timeUpdate(sender: NSDate)
{
    let timeSave = NSDateFormatter() //Creating first object to update time label as 12hr format with AM/PM
    timeSave.timeStyle = NSDateFormatterStyle.ShortStyle //Setting the style for the time selection.
    self.TimeShowOutlet.text = timeSave.stringFromDate(sender) // Getting the string from the selected time and updating the label as 1:40 PM
    let timeCheck = NSDateFormatter() //Creating another object to store time in 24hr format.
    timeCheck.dateFormat = "HH:mm:ss" //Setting the format for the time save.
    let time = timeCheck.stringFromDate(sender) //Getting the time string as 13:40:00
    self.timeSelectedForCheckAvailability = time //At last saving the 24hr format time for further task.
}

After writing this function you can call this where you are choosing the time from date/time picker.

Thanks, Hope this helped.

I came up with the following extension that takes care of removing elements from an Array, assuming the elements in the Array implement Equatable:

extension Array where Element: Equatable {
  
  mutating func removeEqualItems(_ item: Element) {
    self = self.filter { (currentItem: Element) -> Bool in
      return currentItem != item
    }
  }

  mutating func removeFirstEqualItem(_ item: Element) {
    guard var currentItem = self.first else { return }
    var index = 0
    while currentItem != item {
      index += 1
      currentItem = self[index]
    }
    self.remove(at: index)
  }
  
}
  

Usage:

var test1 = [1, 2, 1, 2]
test1.removeEqualItems(2) // [1, 1]

var test2 = [1, 2, 1, 2]
test2.removeFirstEqualItem(2) // [1, 1, 2]

check http://jsfiddle.net/Z22NU/12/

function fnselect(){

    alert($("tr.selected td:first" ).html());
}

This is usually caused by your CSV having been saved along with an (unnamed) index (RangeIndex).

(The fix would actually need to be done when saving the DataFrame, but this isn't always an option.)

Workaround: read_csv with index_col=[0] argument

IMO, the simplest solution would be to read the unnamed column as the index. Specify an index_col=[0] argument to pd.read_csv, this reads in the first column as the index. (Note the square brackets).

df = pd.DataFrame('x', index=range(5), columns=list('abc'))
df

   a  b  c
0  x  x  x
1  x  x  x
2  x  x  x
3  x  x  x
4  x  x  x

# Save DataFrame to CSV.
df.to_csv('file.csv')

<!- ->

pd.read_csv('file.csv')

   Unnamed: 0  a  b  c
0           0  x  x  x
1           1  x  x  x
2           2  x  x  x
3           3  x  x  x
4           4  x  x  x

# Now try this again, with the extra argument.
pd.read_csv('file.csv', index_col=[0])

   a  b  c
0  x  x  x
1  x  x  x
2  x  x  x
3  x  x  x
4  x  x  x

Note
You could have avoided this in the first place by using index=False if the output CSV was created in pandas, if your DataFrame does not have an index to begin with:

df.to_csv('file.csv', index=False)

But as mentioned above, this isn't always an option.

Stopgap Solution: Filtering with str.match

If you cannot modify the code to read/write the CSV file, you can just remove the column by filtering with str.match:

df 

   Unnamed: 0  a  b  c
0           0  x  x  x
1           1  x  x  x
2           2  x  x  x
3           3  x  x  x
4           4  x  x  x

df.columns
# Index(['Unnamed: 0', 'a', 'b', 'c'], dtype='object')

df.columns.str.match('Unnamed')
# array([ True, False, False, False])

df.loc[:, ~df.columns.str.match('Unnamed')]
 
   a  b  c
0  x  x  x
1  x  x  x
2  x  x  x
3  x  x  x
4  x  x  x

If your stored procedure uses linked servers or openquery, they may run quickly by themselves but take a long time to render in SSRS. Some general suggestions:

• Retrieve the data directly from the server where the data is stored by using a different data source instead of using the linked server to retrieve the data.
• Load the data from the remote server to a local table prior to executing the report, keeping the report query simple.
• Use a table variable to first retrieve the data from the remote server and then join with your local tables instead of directly returning a join with a linked server.

I see that the question has been answered, I'm just adding this in case someone has this same issue.

Recursion is a very basic programming technique, and it lends itself to so many problems that listing them is like listing all problems that can be solved by using addition of some kind. Just going through my Lisp solutions for Project Euler, I find: a cross total function, a digit matching function, several functions for searching a space, a minimal text parser, a function splitting a number into the list of its decimal digits, a function constructing a graph, and a function traversing an input file.

The problem is that many if not most mainstream programming languages today do not have tail call optimization so that deep recursion is not feasible with them. This inadequacy means that most programmers are forced to unlearn this natural way of thinking and instead rely on other, arguably less elegant looping constructs.

You can split a string in SQL without needing a function:

DECLARE @bla varchar(MAX)
SET @bla = 'BED40DFC-F468-46DD-8017-00EF2FA3E4A4,64B59FC5-3F4D-4B0E-9A48-01F3D4F220B0,A611A108-97CA-42F3-A2E1-057165339719,E72D95EA-578F-45FC-88E5-075F66FD726C'

-- http://stackoverflow.com/questions/14712864/how-to-query-values-from-xml-nodes
SELECT 
    x.XmlCol.value('.', 'varchar(36)') AS val 
FROM 
(
    SELECT 
    CAST('<e>' + REPLACE(@bla, ',', '</e><e>') + '</e>' AS xml) AS RawXml
) AS b 
CROSS APPLY b.RawXml.nodes('e') x(XmlCol);

If you need to support arbitrary strings (with xml special characters)

DECLARE @bla NVARCHAR(MAX)
SET @bla = '<html>unsafe & safe Utf8CharsDon''tGetEncoded ÄöÜ - "Conex"<html>,Barnes & Noble,abc,def,ghi'

-- http://stackoverflow.com/questions/14712864/how-to-query-values-from-xml-nodes

    CAST('<e>' + REPLACE((SELECT @bla FOR XML PATH('')), ',', '</e><e>') + '</e>' AS xml) AS RawXml
) AS b 
CROSS APPLY b.RawXml.nodes('e') x(XmlCol); 

An important thing to note / "Bootstrap" is just a bunch of CSS rules

a fiddle

HTML

<div class="your-centered-div">
    <img src="http://placehold.it/1120x630&text=Pretend Video 560x315" alt="" />
</div>

CSS

/* key stuff */
.your-centered-div {
    width: 560px; /* you have to have a size or this method doesn't work */
    height: 315px; /* think about making these max-width instead - might give you some more responsiveness */

    position: absolute; /* positions out of the flow, but according to the nearest parent */
    top: 0; right: 0; /* confuse it i guess */
    bottom: 0; left: 0;
    margin: auto; /* make em equal */
}

Fully working jsFiddle is here.

EDIT

I mostly use this these days:

straight CSS

.centered-thing {
    position: absolute;
    margin: auto;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}

if your use stylus/mixins ( you should... it's the best )

center-center()
    absolute()
    margin auto
    top 50%
    left 50%
    transform translate(-50%,-50%)

This way... you don't need to know the size of the element - and the translate is based of it's size - So, -50% of itself. Neat.

Assuming that "part within rectangle don't have content color" means that you want different fills within the rectangle; you need to draw a rectangle within your rectangle then with stroke width 0 and the desired fill colour(s).

For example:

DrawView.java

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.view.View;

public class DrawView extends View {
    Paint paint = new Paint();

    public DrawView(Context context) {
        super(context);            
    }

    @Override
    public void onDraw(Canvas canvas) {
        paint.setColor(Color.BLACK);
        paint.setStrokeWidth(3);
        canvas.drawRect(30, 30, 80, 80, paint);
        paint.setStrokeWidth(0);
        paint.setColor(Color.CYAN);
        canvas.drawRect(33, 60, 77, 77, paint );
        paint.setColor(Color.YELLOW);
        canvas.drawRect(33, 33, 77, 60, paint );

    }

}

The activity to start it:

StartDraw.java

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;

public class StartDraw extends Activity {
    DrawView drawView;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        drawView = new DrawView(this);
        drawView.setBackgroundColor(Color.WHITE);
        setContentView(drawView);

    }
}

...will turn out this way:

Access 2007 can lose the CurrentDb: see http://support.microsoft.com/kb/167173, so in the event of getting "Object Invalid or no longer set" with the examples, use:

I took Eugen Rieck's answer and worked with it. My code adds the following:

1. ps ax includes grep, so I excluded it with grep -Eiv 'grep'
2. Added a few ifs and echoes to make it human-readable.

I've created a file, named it killserver, here it goes:

#!/bin/bash
PROCESS_TO_KILL=bin/node
PROCESS_LIST=`ps ax | grep -Ei ${PROCESS_TO_KILL} | grep -Eiv 'grep' | awk ' { print $1;}'`
KILLED=
for KILLPID in $PROCESS_LIST; do
  if [ ! -z $KILLPID ];then
    kill -9 $KILLPID
    echo "Killed PID ${KILLPID}"
    KILLED=yes
  fi
done

if [ -z $KILLED ];then
    echo "Didn't kill anything"
fi

Results

?  myapp git:(master) bash killserver
Killed PID 3358
Killed PID 3382
Killed
?  myapp git:(master) bash killserver
Didn't kill anything

If your slices were of the same size, it would work:

arr := []int{1, 2, 3}
tmp := []int{0, 0, 0}
i := copy(tmp, arr)
fmt.Println(i)
fmt.Println(tmp)
fmt.Println(arr)

Would give:

3
[1 2 3]
[1 2 3]

From "Go Slices: usage and internals":

The copy function supports copying between slices of different lengths (it will copy only up to the smaller number of elements)

The usual example is:

t := make([]byte, len(s), (cap(s)+1)*2)
copy(t, s)
s = t

The reason for that error is that you are trying to copy a folder which requires -r option also to cp Thanks

It is a very simple and effective utility build in jquery to implement pagination on html table http://tablesorter.com/docs/example-pager.html

Download the plugin from http://tablesorter.com/addons/pager/jquery.tablesorter.pager.js

After adding this plugin add following code in head script

$(document).ready(function() { 
    $("table") 
    .tablesorter({widthFixed: true, widgets: ['zebra']}) 
    .tablesorterPager({container: $("#pager")}); 
}); 

There is no config file unless you create one yourself. However, the port is a parameter of the listen() function. For example, to listen on port 8124:

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(8124, "127.0.0.1");
console.log('Server running at http://127.0.0.1:8124/');

If you're having problems finding a port that's open, you can go to the command line and type:

netstat -ano

To see a list of all ports in use per adapter.

If you don't want to use the shutil module you can just use the os module.

from os import listdir, rmdir, remove
for i in listdir(directoryToRemove):
    os.remove(os.path.join(directoryToRemove, i))
rmdir(directoryToRemove) # Now the directory is empty of files

For completeness, guava also has a handy utility for this

ByteStreams.copy(input, output);

I like Consolas a lot. This top-10 list is a good resource for others. It includes examples and descriptions.

1. You need the specify the exact filename, including the file extension, e.g. 10_Random.txt.
2. The file needs to be in the same directory as the executable if you want to refer to it without any kind of explicit path.
3. While we're at it, you need to check for an int before reading an int. It is not safe to check with hasNextLine() and then expect an int with nextInt(). You should use hasNextInt() to check that there actually is an int to grab. How strictly you choose to enforce the one integer per line rule is up to you, of course.

You can add an undecorated JDialog like this:

import java.awt.event.*;

import javax.swing.*;

public class TestSwing {
  public static void main(String[] args) throws Exception {
    JFrame frame = new JFrame("Parent");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(800, 600);
    frame.setVisible(true);

    final JDialog dialog = new JDialog(frame, "Child", true);    
    dialog.setSize(300, 200);
    dialog.setLocationRelativeTo(frame);
    JButton button = new JButton("Button");
    button.addActionListener(new ActionListener() {
      @Override
      public void actionPerformed(ActionEvent e) {
        dialog.dispose();
      }
    });
    dialog.add(button);
    dialog.setUndecorated(true);
    dialog.setVisible(true);
  }
}

Integer value of ARGB color to hexadecimal string:

String hex = Integer.toHexString(color); // example for green color FF00FF00

Hexadecimal string to integer value of ARGB color:

int color = (Integer.parseInt( hex.substring( 0,2 ), 16) << 24) + Integer.parseInt( hex.substring( 2 ), 16);

From man curl:

-x, --proxy <[protocol://][user:password@]proxyhost[:port]>

     Use the specified HTTP proxy. 
     If the port number is not specified, it is assumed at port 1080.

General way:

export http_proxy=http://your.proxy.server:port/

Then you can connect through proxy from (many) application.

And, as per comment below, for https:

export https_proxy=https://your.proxy.server:port/

Both are poles on two different axis:

• strongly typed vs. weakly typed
• statically typed vs. dynamically typed

Strongly typed means, a will not be automatically converted from one type to another. Weakly typed is the opposite: Perl can use a string like "123" in a numeric context, by automatically converting it into the int 123. A strongly typed language like python will not do this.

Statically typed means, the compiler figures out the type of each variable at compile time. Dynamically typed languages only figure out the types of variables at runtime.

The key is the margin: 0 auto; on the inner div. A proof-of-concept example:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<body>
    <div style="background-color: blue; width: 100%;">
        <div style="background-color: yellow; width: 940px; margin: 0 auto;">
            Test
        </div>
    </div>
</body>
</html>

By default, read.csv checks the first few rows of your data to see whether to treat each variable as numeric. If it finds non-numeric values, it assumes the variable is character data, and character variables are converted to factors.

It looks like the PTS and MP variables in your dataset contain non-numerics, which is why you're getting unexpected results. You can force these variables to numeric with

point <- as.numeric(as.character(point))
time <- as.numeric(as.character(time))

But any values that can't be converted will become missing. (The R FAQ gives a slightly different method for factor -> numeric conversion but I can never remember what it is.)

Figured it out.

You'll have to add the following gradle dependency :

compile 'com.android.support:recyclerview-v7:+'

another issue I had compiling was the compileSdkVersion. Apparently you'll have to compile it against android-L

Your build.gradle file should look something like this:

apply plugin: 'android'
android {
    compileSdkVersion 'android-L'
    buildToolsVersion '19.1.0'
    [...]
}
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:recyclerview-v7:+'
}

some problem, but I find the solution, this is :

2 February Feb 28 (29 in leap years)

this is my code

 public string GetCountArchiveByMonth(int iii)
        {
// iii: is number of months, use any number other than (**2**)

            con.Open();

            SqlCommand cmd10 = con.CreateCommand();
            cmd10.CommandType = CommandType.Text;
            cmd10.CommandText = "select count(id_post) from posts where dateadded between CONVERT(VARCHAR, @start, 103) and CONVERT(VARCHAR, @end, 103)";
            cmd10.Parameters.AddWithValue("@start", "" + iii + "/01/2019");
            cmd10.Parameters.AddWithValue("@end", "" + iii + "/30/2019");
            string result = cmd10.ExecuteScalar().ToString();

            con.Close();

            return result;
        }

now for test

 lbl1.Text = GetCountArchiveByMonth(**7**).ToString();  // here use any number other than (**2**)

**

because of check **February** is maxed 28 days,

**

C++ "one-liner":

#include <iostream>
#include <iterator>
#include <numeric>
using namespace std;

int main() {
    cout << accumulate(istream_iterator<int>(cin), istream_iterator<int>(), 0) << endl;
}

There are multiple ways you can do this but I am not sure which one is the best practice. The first approach is you can append an iFrame in the dialog container on the fly with your given link:

$("#dialog").append($("<iframe />").attr("src", "your link")).dialog({dialogoptions});

Another would be to load the content of your external link into the dialog container using ajax.

$("#dialog").load("yourajaxhandleraddress.htm").dialog({dialogoptions});

Both works fine but depends on the external content.

Interfaces just provide a list of things a class will provide, not an actual implementation of those things, which is what your static item is.

If you want statics, use an abstract class and inherit it, otherwise, remove the static.

Hope that helps!

Here's one way:

CString str;
str.Format("%d", 5);

In your case, try _T("%d") or L"%d" rather than "%d"

Please find attached my dynamic solution if you want to increase the size of an array dynamically after clicking on a button (This is how I got to this question).

Allocation of necessary variables:

  array = [1];
  arraySize: number;

Declare the function that adds an element to the array:

increaseArrayElement() {
   this.arraySize = this.array[this.array.length - 1 ];
   this.arraySize += 1;
   this.array.push(this.arraySize);
   console.log(this.arraySize);
}

Invoke the function in html

  <button md-button (click)="increaseArrayElement()" >
      Add element to array
  </button>

Iterate through array with ngFor:

<div *ngFor="let i of array" >
  iterateThroughArray: {{ i }}
</div>

Sending a get request with axios from a webpage, I needed (finally) to enable also Geocoding API.

I also have Places API, Maps Javascript API, and Geolocation API.

Thanks to these guys

1. Open a command prompt as an Administrator.

2. Enter slmgr /upk and wait for this to complete. This will uninstall the current product key from Windows and put it into an unlicensed state.

3. Enter slmgr /cpky and wait for this to complete. This will remove the product key from the registry if it's still there.

4. Enter slmgr /rearm and wait for this to complete. This is to reset the Windows activation timers so the new users will be prompted to activate Windows when they put in the key.

This should put the system back to a pre-key state.

Hope this helps you out!

This part has problems:

Card* cardArray;
void Deck() {
    cardArray = new Card[NUM_TOTAL_CARDS];
    int cardCount = 0;
    for (int i = 0; i > NUM_SUITS; i++) {  //Error
        for (int j = 0; j > NUM_RANKS; j++) { //Error
            cardArray[cardCount] = Card(Card::Rank(i), Card::Suit(j) );
            cardCount++;
         }
    }
 }

1. cardArray is a dynamic array, but not a member of Card class. It is strange if you would like to initialize a dynamic array which is not member of the class
2. void Deck() is not constructor of class Deck since you missed the scope resolution operator. You may be confused with defining the constructor and the function with name Deck and return type void.
3. in your loops, you should use < not > otherwise, loop will never be executed.

HTML 5 allows summary tag, details element. That can be used to view or hide (collapse/expand) a section. Link

Find/search for file "xampp-control.ini" where you installed XAMPP server (e.g., D:\Server or C:\xampp).

Then edit in n the [Autostart] section:

Apache=1
MySQL=1
FileZilla=0
Mercury=0
Tomcat=0

Where 1 = true and 0 = false

That's so simple.

Try this expression...

string-join(//element3/(concat(element4/text(), '.', element5/text())), "
")

Without a class or an id, and with your specific html:

table tr td label {display:none}

Otherwise if you have jQuery

$('label[for="foo"]').css('display', 'none');

Make sure this is not code smell. Is it possible to reverse the logic and be 'inclusive' rather than 'exclusive'?

List<String> names = ....
List<String> reducedNames = ....
for (String name : names) {
   // Do something
   if (conditionToIncludeMet)
       reducedNames.add(name);
}
return reducedNames;

The situation that led me to this page involved old code that looped through a List using indecies to remove elements from the List. I wanted to refactor it to use the foreach style.

It looped through an entire list of elements to verify which ones the user had permission to access, and removed the ones that didn't have permission from the list.

List<Service> services = ...
for (int i=0; i<services.size(); i++) {
    if (!isServicePermitted(user, services.get(i)))
         services.remove(i);
}

To reverse this and not use the remove:

List<Service> services = ...
List<Service> permittedServices = ...
for (Service service:services) {
    if (isServicePermitted(user, service))
         permittedServices.add(service);
}
return permittedServices;

When would "remove" be preferred? One consideration is if gien a large list or expensive "add", combined with only a few removed compared to the list size. It might be more efficient to only do a few removes rather than a great many adds. But in my case the situation did not merit such an optimization.

I think you mean:

unsigned long n;
printf("%lu", n);   // unsigned long

or

long n;
printf("%ld", n);   // signed long

It looks like get-pip.py has been updated to use the environment variables http_proxy and https_proxy.

Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
python get-pip.py

Linux/OS X:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E python get-pip.py

However if this still doesn't work for you, you can always install pip through a proxy using setuptools' easy_install by setting the same environment variables.

Windows:

set http_proxy=http://proxy.myproxy.com
set https_proxy=https://proxy.myproxy.com
easy_install pip

Linux/OS X:

export http_proxy=http://proxy.myproxy.com
export https_proxy=https://proxy.myproxy.com
sudo -E easy_install pip

Then once it's installed, use:

pip install --proxy="user:password@server:port" packagename

From the pip man page:

--proxy
Have pip use a proxy server to access sites. This can be specified using "user:[email protected]:port" notation. If the password is left out, pip will ask for it.

In general we have default-initialization in first case and value-initialization in second case.

For example: in case with int (POD type):

• int* test = new int - we have any initialization and value of *test can be any.

• int* test = new int() - *test will have 0 value.

next behaviour depended from your type Test. We have defferent cases: Test have defult constructor, Test have generated default constructor, Test contain POD member, non POD member...

I have had the same problem and came acrosse this site.

the solution to just set another "filename" in the

... for output as ... command was very simple and useful.

in addition (beyond the Application.GetSaveAsFilename() Dialog)

it is very simple to set a** new filename** just using

the replace command, so you may change the filename/extension

eg. (as from the first post)

sFileName = "C:\filelocation"
iFileNum = FreeFile

Open sFileName For Input As iFileNum
content = (...edit the content) 

Close iFileNum

now just set:

newFilename = replace(sFilename, ".txt", ".csv") to change the extension

or

newFilename = replace(sFilename, ".", "_edit.") for a differrent filename

and then just as before

iFileNum = FreeFile
Open newFileName For Output As iFileNum

Print #iFileNum, content
Close iFileNum 

I surfed over an hour to find out how to rename a txt-file,

with many different solutions, but it could be sooo easy :)

Open up the postgres terminal with the databse you would like:

psql dbname (run this line in a terminal)

then, run this command in the postgres environment

\d

This will describe all tables by name. Basically a list of tables by name ascending.

Then you can try this to describe a table by fields:

\d tablename.

Hope this helps.

Use Environment.NewLine for line breaks.

There aren't a lot of them because they would be in competition with JFreeChart, and it's awesome. You can get documentation and examples by downloading the developer's guide. There are also tons of free online tutorials if you search for them.

Alternatively you can do like this.

RUN addgroup demo && adduser -DH -G demo demo

First command creates group called demo. Second command creates demo user and adds him to previously created demo group.

Flags stands for:

-G Group
-D Don't assign password
-H Don't create home directory

If you want to use it as a IBInspectable property for your views you can add this extension

import UIKit

extension UIView {

    private static var _addShadow:Bool = false

    @IBInspectable var addShadow:Bool {
        get {
            return UIView._addShadow
        }
        set(newValue) {
            if(newValue == true){
                layer.masksToBounds = false
                layer.shadowColor = UIColor.black.cgColor
                layer.shadowOpacity = 0.075
                layer.shadowOffset = CGSize(width: 0, height: -3)
                layer.shadowRadius = 1

                layer.shadowPath = UIBezierPath(rect: bounds).cgPath
                layer.shouldRasterize = true
                layer.rasterizationScale =  UIScreen.main.scale
            }
        }
    }

}

This may also tangentially help, to understand if a logging request (from the code) at a certain level will result in it actually being logged given the effective logging level that a deployment is configured with. Decide what effective level you want to configure you deployment with from the other Answers here, and then refer to this to see if a particular logging request from your code will actually be logged then...

For examples:

• "Will a logging code line that logs at WARN actually get logged on my deployment configured with ERROR?" The table says, NO.
• "Will a logging code line that logs at WARN actually get logged on my deployment configured with DEBUG?" The table says, YES.

from logback documentation:

In a more graphic way, here is how the selection rule works. In the following table, the vertical header shows the level of the logging request, designated by p, while the horizontal header shows effective level of the logger, designated by q. The intersection of the rows (level request) and columns (effective level) is the boolean resulting from the basic selection rule.

So a code line that requests logging will only actually get logged if the effective logging level of its deployment is less than or equal to that code line's requested level of severity.

Christian's answer works well and shows how you can loop through each hash table item using the GetEnumerator method. You can also loop through using the keys property. Here is an example how:

$hash = @{
    a = 1
    b = 2
    c = 3
}
$hash.Keys | % { "key = $_ , value = " + $hash.Item($_) }

Output:

key = c , value = 3
key = a , value = 1
key = b , value = 2

Functional Interfaces: An interface is called a functional interface if it has a single abstract method irrespective of the number of default or static methods. Functional Interface are use for lamda expression. Runnable, Callable, Comparable, Comparator are few examples of Functional Interface.

KeyNotes:

• Annotation @FunctionalInterface is used(Optional).
• It should have only 1 abstract method(irrespective of number of default and static methods).
• Two abstract method gives compilation error(Provider @FunctionalInterface annotation is used).

This thread talks more in detail about what benefit functional Interface gives over anonymous class and how to use them.

What you are looking for is an AMD compliant loader (like require.js).

http://requirejs.org/

http://requirejs.org/docs/whyamd.html

There are many good open source ones if you look it up. Basically this allows you to define a module of code, and if it is dependent on other modules of code, it will wait until those modules have finished downloading before proceeding to run. This way you can load 10 modules asynchronously and there should be no problems even if one depends on a few of the others to run.

Using DirectoryIterator and recursion correctly:

function deleteFilesThenSelf($folder) {
    foreach(new DirectoryIterator($folder) as $f) {
        if($f->isDot()) continue; // skip . and ..
        if ($f->isFile()) {
            unlink($f->getPathname());
        } else if($f->isDir()) {
            deleteFilesThenSelf($f->getPathname());
        }
    }
    rmdir($folder);
}

This should work:

if (!string.IsNullOrWhiteSpace(dateTimeEnd))
    eventCustom.DateTimeEnd = DateTime.Parse(dateTimeEnd);
else
    eventCustom.DateTimeEnd = null;

Note that this will throw an exception if the string is not in the correct format.

To be able to pretty print from the command line and be able to have control over the indentation etc. you can set up an alias similar to this:

alias jsonpp="python -c 'import sys, json; print json.dumps(json.load(sys.stdin), sort_keys=True, indent=2)'"

And then use the alias in one of these ways:

cat myfile.json | jsonpp
jsonpp < myfile.json

For z-index to work, you also need to give it a position:

header {
    width: 100%;
    height: 100px;
    background: url(../img/top.png) repeat-x;
    z-index: 110;
    position: relative;
}

Clearly you aren't sending the data with ObjectOutputStream: you are just writing the bytes.

• If you read with readObject() you must write with writeObject().
• If you read with readUTF() you must write with writeUTF().
• If you read with readXXX() you must write with writeXXX(), for most values of XXX.

Since the accepted answer requires IIS Manager, and IIS Express doesn't have IIS Manager or any UI, here's the solution for you IIS Express users (and should work for everyone else too):

When you open Visual Studio and get the error message, right-click the project Solution Explorer and choose "Edit {ProjectName}.csproj"

In the project file, change the following line:
<UseIIS>True</UseIIS>
to
<UseIIS>False</UseIIS>
Save the file.

Now reload your project.
Done.

You'll then be able to open your project. If at this point, you want to use IIS, simply go to your project properties, click the "Web" tab, and select the option to use IIS. There's the button there to "Create Virtual Directory". It may tell you that you need to run Visual Studio as an administrator to create that directory, so do that if needed.

SQL injection can be a tricky problem but there are ways around it. Your risk is reduced your risk simply by using an ORM like Linq2Entities, Linq2SQL, NHibrenate. However you can have SQL injection problems even with them.

The main thing with SQL injection is user controlled input (as is with XSS). In the most simple example if you have a login form (I hope you never have one that just does this) that takes a username and password.

SELECT * FROM Users WHERE Username = '" + username + "' AND password = '" + password + "'"

If a user were to input the following for the username Admin' -- the SQL Statement would look like this when executing against the database.

SELECT * FROM Users WHERE Username = 'Admin' --' AND password = ''

In this simple case using a paramaterized query (which is what an ORM does) would remove your risk. You also have a the issue of a lesser known SQL injection attack vector and that's with stored procedures. In this case even if you use a paramaterized query or an ORM you would still have a SQL injection problem. Stored procedures can contain execute commands, and those commands themselves may be suceptable to SQL injection attacks.

CREATE PROCEDURE SP_GetLogin @username varchar(100), @password varchar(100) AS
DECLARE @sql nvarchar(4000)
SELECT @sql = ' SELECT * FROM users' +
              ' FROM Product Where username = ''' + @username + ''' AND password = '''+@password+''''

EXECUTE sp_executesql @sql

So this example would have the same SQL injection problem as the previous one even if you use paramaterized queries or an ORM. And although the example seems silly you'd be surprised as to how often something like this is written.

My recommendations would be to use an ORM to immediately reduce your chances of having a SQL injection problem, and then learn to spot code and stored procedures which can have the problem and work to fix them. I don't recommend using ADO.NET (SqlClient, SqlCommand etc...) directly unless you have to, not because it's somehow not safe to use it with parameters but because it's that much easier to get lazy and just start writing a SQL query using strings and just ignoring the parameters. ORMS do a great job of forcing you to use parameters because it's just what they do.

Next Visit the OWASP site on SQL injection https://www.owasp.org/index.php/SQL_Injection and use the SQL injection cheat sheet to make sure you can spot and take out any issues that will arise in your code. https://www.owasp.org/index.php/SQL_Injection_Prevention_Cheat_Sheet finally I would say put in place a good code review between you and other developers at your company where you can review each others code for things like SQL injection and XSS. A lot of times programmers miss this stuff because they're trying to rush out some feature and don't spend too much time on reviewing their code.

i had the same issue, but I just typed export on top and erased the default one on the bottom. Scroll down and check the comments.

import React, { Component } from "react";

export class Counter extends Component { // type this  
export default Counter; // this is eliminated  

Could you please have a look at: http://jsfiddle.net/4Zw3M/1/.

Basically, the data is stored in an Array and the options are added accordingly. I think the code says more than a thousand words.

var data = [ // The data
    ['ten', [
        'eleven','twelve'
    ]],
    ['twenty', [
        'twentyone', 'twentytwo'
    ]]
];

$a = $('#a'); // The dropdowns
$b = $('#b');

for(var i = 0; i < data.length; i++) {
    var first = data[i][0];
    $a.append($("<option>"). // Add options
       attr("value",first).
       data("sel", i).
       text(first));
}

$a.change(function() {
    var index = $(this).children('option:selected').data('sel');
    var second = data[index][1]; // The second-choice data

    $b.html(''); // Clear existing options in second dropdown

    for(var j = 0; j < second.length; j++) {
        $b.append($("<option>"). // Add options
           attr("value",second[j]).
           data("sel", j).
           text(second[j]));
    }
}).change(); // Trigger once to add options at load of first choice

To set a session-timeout that never expires is not desirable because you would be reliable on the user to push the logout-button every time he's finished to prevent your server of too much load (depending on the amount of users and the hardware). Additionaly there are some security issues you might run into you would rather avoid.

The reason why the session gets invalidated while the server is still working on a task is because there is no communication between client-side (users browser) and server-side through e.g. a http-request. Therefore the server can't know about the users state, thinks he's idling and invalidates the session after the time set in your web.xml.

To get around this you have several possibilities:

• You could ping your backend while the task is running to touch the session and prevent it from being expired
• increase the <session-timeout> inside the server but I wouldn't recommend this
• run your task in a dedicated thread which touches (extends) the session while working or notifies the user when the thread has finished

There was a similar question asked, maybe you can adapt parts of this solution in your project. Have a look at this.

Hope this helps, have Fun!

First, I get the high side of the char. After, get the low side. Convert all of things in HexString and put the prefix.

int hs = (int) c  >> 8;
int ls = hs & 0x000F;

String highSide = Integer.toHexString(hs);
String lowSide = Integer.toHexString(ls);
lowSide = Integer.toHexString(hs & 0x00F0);
String hexa = Integer.toHexString( (int) c );

System.out.println(c+" = "+"\\u"+highSide+lowSide+hexa);

Combining several already given answers, I'm shipping on it as well with my implementation:

@implementation UIView (AppNameAdditions)

- (UIViewController *)appName_viewController {
    /// Finds the view's view controller.

    // Take the view controller class object here and avoid sending the same message iteratively unnecessarily.
    Class vcc = [UIViewController class];

    // Traverse responder chain. Return first found view controller, which will be the view's view controller.
    UIResponder *responder = self;
    while ((responder = [responder nextResponder]))
        if ([responder isKindOfClass: vcc])
            return (UIViewController *)responder;

    // If the view controller isn't found, return nil.
    return nil;
}

@end

The category is part of my ARC-enabled static library that I ship on every application I create. It's been tested several times and I didn't find any problems or leaks.

P.S.: You don't need to use a category like I did if the concerned view is a subclass of yours. In the latter case, just put the method in your subclass and you're good to go.

The OData protocol is built on top of the AtomPub protocol. The AtomPub protocol is one of the best examples of REST API design. So, in a sense you are right - the OData is just another REST API and each OData implementation is a REST-ful web service.

The difference is that OData is a specific protocol; REST is architecture style and design pattern.

when you are dealing with popups window.opener plays an important role, because we have to deal with fields of parent page as well as child page, when we have to use values on parent page we can use window.opener or we want some data on the child window or popup window at the time of loading then again we can set the values using window.opener

I hope this will help you

Create table :

create table users (id int,first_name varchar(10),last_name varchar(10));

Insert values into the table :

insert into users (id,first_name,last_name) values(1,'Abhishek','Anand');

For strings of non-numbers, try: except: is actually slower than regular expressions. For strings of valid numbers, regex is slower. So, the appropriate method depends on your input.

If you find that you are in a performance bind, you can use a new third-party module called fastnumbers that provides a function called isfloat. Full disclosure, I am the author. I have included its results in the timings below.

As you can see

• try: except: was fast for numeric input but very slow for an invalid input
• regex is very efficient when the input is invalid
• fastnumbers wins in both cases

The trouble with using dates as x-values, is that if you want a bar chart like in your second picture, they are going to be wrong. You should either use a stacked bar chart (colours on top of each other) or group by date (a "fake" date on the x-axis, basically just grouping the data points).

import numpy as np
import matplotlib.pyplot as plt

N = 3
ind = np.arange(N)  # the x locations for the groups
width = 0.27       # the width of the bars

fig = plt.figure()
ax = fig.add_subplot(111)

yvals = [4, 9, 2]
rects1 = ax.bar(ind, yvals, width, color='r')
zvals = [1,2,3]
rects2 = ax.bar(ind+width, zvals, width, color='g')
kvals = [11,12,13]
rects3 = ax.bar(ind+width*2, kvals, width, color='b')

ax.set_ylabel('Scores')
ax.set_xticks(ind+width)
ax.set_xticklabels( ('2011-Jan-4', '2011-Jan-5', '2011-Jan-6') )
ax.legend( (rects1[0], rects2[0], rects3[0]), ('y', 'z', 'k') )

def autolabel(rects):
    for rect in rects:
        h = rect.get_height()
        ax.text(rect.get_x()+rect.get_width()/2., 1.05*h, '%d'%int(h),
                ha='center', va='bottom')

autolabel(rects1)
autolabel(rects2)
autolabel(rects3)

plt.show()

Since stop is boolean you can change that part to:

//...
if(stop) // Or to: if (stop == true)
{
   sb.append("y");
   getWhoozitYs();
}
return sb.toString();
//...

Having read various versions of this question and searching around I've come up with quite a clean, js-free, solution. It's similar to @allcaps solution but avoids the issue of the input font being changed away from the main document font.

Use the ::input-placeholder attribute to specifically style the placeholder text. This allows you to use your icon font as the placeholder font and your body (or other font) as the actual input text. Currently you need to specify vendor-specific selectors.

This works well as long as you don't need a combination of icon and text in your input element. If you do then you'll need to put up with the placeholder text being default browser font (plain serif on mine) for words.

E.g.
HTML

<p class="wrapper">
    <input class="icon" type="text" placeholder="&#61442;" />
</p>

CSS

.wrapper {
    font-family:'arial', sans-serif;
}
input.icon::-webkit-input-placeholder {
    font-family:'FontAwesome';
}

Fiddle with browser prefixed selectors: http://jsfiddle.net/gA4rx/78/

Note that you need to define each browser-specific selector as a seperate rule. If you combine them the browser will ignore it.

Not enough reputation to comment yet so I'll just put this here:

To expand on Micah's answer - the browser runs your code top to bottom, so if you write:

<div id="chart"></div>
<script>var svg = d3.select("#chart").append("svg:svg");</script>

The browser will create a div with id "chart", and then run your script, which will try to find that div, and, hurray, success.

Otherwise if you write:

<script>var svg = d3.select("#chart").append("svg:svg");</script>
<div id="chart"></div>

The browser runs your script, and tries to find a div with id chart, but it hasn't been created yet so it fails.

THEN the browser creates a div with id "chart".

i resolved this problem after disable ESLint extention.

The term "clone" is ambiguous (though the Java class library includes a Cloneable interface) and can refer to a deep copy or a shallow copy. Deep/shallow copies are not specifically tied to Java but are a general concept relating to making a copy of an object, and refers to how members of an object are also copied.

As an example, let's say you have a person class:

class Person {
    String name;
    List<String> emailAddresses
}

How do you clone objects of this class? If you are performing a shallow copy, you might copy name and put a reference to emailAddresses in the new object. But if you modified the contents of the emailAddresses list, you would be modifying the list in both copies (since that's how object references work).

A deep copy would mean that you recursively copy every member, so you would need to create a new List for the new Person, and then copy the contents from the old to the new object.

Although the above example is trivial, the differences between deep and shallow copies are significant and have a major impact on any application, especially if you are trying to devise a generic clone method in advance, without knowing how someone might use it later. There are times when you need deep or shallow semantics, or some hybrid where you deep copy some members but not others.

I think that most important information is: Elements in xib are automatically in subviews of view. Subviews is NSArray. NSArray owns it's elements. etc have strong pointers on them. So in most cases you don't want to create another strong pointer (IBOutlet)

And with ARC you don't need to do anything in viewDidUnload

Try this, you can create an extension method like this:

    public static string ContentToString(this HttpContent httpContent)
    {
        var readAsStringAsync = httpContent.ReadAsStringAsync();
        return readAsStringAsync.Result;
    }

and then, simple call the extension method:

txtBlock.Text = response.Content.ContentToString();

I hope this help you ;-)

I found a better way of doing it so you can get a input from a txtbox or have something be generated in that text box and be able to click a button to do it.!

import java.awt.datatransfer.*;
import java.awt.Toolkit;

private void /* Action performed when the copy to clipboard button is clicked */ {
    String ctc = txtCommand.getText().toString();
    StringSelection stringSelection = new StringSelection(ctc);
    Clipboard clpbrd = Toolkit.getDefaultToolkit().getSystemClipboard();
    clpbrd.setContents(stringSelection, null);
}

// txtCommand is the variable of a text box

Because I have yet to see an example that works for my use case, here is the most full-proof solution that I was able to realize.

dd {_x000D_
    margin: 0;_x000D_

Strangely enough, it doesn't work with display: inline-block. I suppose that if you need to set the size of any of the dt elements or dd elements, you could set the dl's display as display: flexbox; display: -webkit-flex; display: flex; and the flex shorthand of the dd elements and the dt elements as something like flex: 1 1 50% and display as display: inline-block. But I haven't tested that, so approach with caution.

I solve the problem. This is Layout:

 <android.support.design.widget.TextInputLayout
           android:id="@+id/til_username"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:hint="@string/username"
           >

           <android.support.v7.widget.AppCompatEditText android:id="@+id/et_username"
               android:layout_width="match_parent"
               android:layout_height="wrap_content"
               android:singleLine="true"
               />
       </android.support.design.widget.TextInputLayout>

This is Style:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>
<!-- Application theme. -->


 <style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
        <item name="colorAccent">@color/pink</item>
        <item name="colorControlNormal">@color/purple</item>
        <item name="colorControlActivated">@color/yellow</item>
    </style>

You should use your theme in application:

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
</application>

In Linux it's more likely that extensions to existing editors will be more mature than entirely new ones. Thus, the two stalwarts (vi and emacs) are likely to have packages available.

EDIT: Indeed, here's the vi one:

http://vim-latex.sourceforge.net/

... and here's the emacs one:

http://www.gnu.org/software/auctex/

I have to say, I'm a vi man, but the emacs package looks rather spiffy: it includes the ability to embed preview images of formulas in your emacs buffer.

For smaller files you could use this:

& C:\windows\system32\more +1 oldfile.csv > newfile.csv | out-null

... but it's not very effective at processing my example file of 16MB. It doesn't seem to terminate and release the lock on newfile.csv.

Just wanted to show that there is no performance difference between the 2 main ways of doing it:

df = pd.DataFrame(np.random.randint(0,10,size=(100, 4)), columns=list('ABCD'))

def loc():
    df1.loc[df1["A"] == 2] = 5
%timeit loc
19.9 ns ± 0.0873 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)


def replace():
    df2['A'].replace(
        to_replace=2,
        value=5,
        inplace=True
    )
%timeit replace
19.6 ns ± 0.509 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

Maybe using Where() before First() can help you, as my problem has been solved in this case.

var documentRow = _dsACL.Documents.Where(o => o.ID == id).FirstOrDefault();

in Bootstrap, web inspector says the Headings are set to 'inherit'

all i needed to set my page to the new font was

div, p {font-family: Algerian}

that's in .scss

Another alternative that only affects the current connection:

SET SESSION query_cache_type=0;

If you use GNU find, since version 4.3.3 you can do:

find -newerct "1 Aug 2013" ! -newerct "1 Sep 2013" -ls

It will accept any date string accepted by GNU date -d.

You can change the c in -newerct to any of a, B, c, or m for looking at atime/birth/ctime/mtime.

Another example - list files modified between 17:30 and 22:00 on Nov 6 2017:

find -newermt "2017-11-06 17:30:00" ! -newermt "2017-11-06 22:00:00" -ls

Full details from man find:

   -newerXY reference
          Compares the timestamp of the current file with reference.  The reference argument is normally the name of a file (and one of its timestamps  is  used
          for  the  comparison)  but  it may also be a string describing an absolute time.  X and Y are placeholders for other letters, and these letters select
          which time belonging to how reference is used for the comparison.

          a   The access time of the file reference
          B   The birth time of the file reference
          c   The inode status change time of reference
          m   The modification time of the file reference
          t   reference is interpreted directly as a time

          Some combinations are invalid; for example, it is invalid for X to be t.  Some combinations are not implemented on all systems; for example B  is  not
          supported on all systems.  If an invalid or unsupported combination of XY is specified, a fatal error results.  Time specifications are interpreted as
          for the argument to the -d option of GNU date.  If you try to use the birth time of a reference file, and the birth time cannot be determined, a fatal
          error  message  results.   If  you  specify a test which refers to the birth time of files being examined, this test will fail for any files where the
          birth time is unknown.

The above answers illustrate the reason for this java.net.SocketException: Broken pipe: the other end closed the connection. I would like to share experience what happened when I encountered it:

1. in a client's request, the Content-Type header is mistakenly set larger than request body actually is (in fact there was no body at all)
2. the bottom service in tomcat socket was waiting for that sized body data (http is on TCP which ensures delivery by encapsulating and ...)
3. when 60 seconds expired, tomcat throws time out exception: Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception java.net.SocketTimeoutException: null
4. client receives a response with status code 500 because of the timeout exception.
5. client close connection (because it receives response).
6. tomcat throws java.net.SocketException: Broken pipe because client closed it.

Sometimes, tomcat does not throw broken pip exception, because timeout exception close the connection, why such a difference is confusing me too.

Like sgibb said it was an if problem, it had nothing to do with | or ||.

Here is another way to solve your problem:

for (i in 1:nrow(trip)) {
  if(trip$Ref.y[i]=='G' & trip$Variant.y[i]=='T'|trip$Ref.y[i]=='C' & trip$Variant.y[i]=='A') {
    trip[i, 'mutType'] <- "G:C to T:A"
  }
  else if(trip$Ref.y[i]=='G' & trip$Variant.y[i]=='C'|trip$Ref.y[i]=='C' & trip$Variant.y[i]=='G') {
    trip[i, 'mutType'] <- "G:C to C:G"
  }
  else if(trip$Ref.y[i]=='G' & trip$Variant.y[i]=='A'|trip$Ref.y[i]=='C' & trip$Variant.y[i]=='T') {
    trip[i, 'mutType'] <- "G:C to A:T"
  }
  else if(trip$Ref.y[i]=='A' & trip$Variant.y[i]=='T'|trip$Ref.y[i]=='T' & trip$Variant.y[i]=='A') {
    trip[i, 'mutType'] <- "A:T to T:A"
  }
  else if(trip$Ref.y[i]=='A' & trip$Variant.y[i]=='G'|trip$Ref.y[i]=='T' & trip$Variant.y[i]=='C') {
    trip[i, 'mutType'] <- "A:T to G:C"
  }
  else if(trip$Ref.y[i]=='A' & trip$Variant.y[i]=='C'|trip$Ref.y[i]=='T' & trip$Variant.y[i]=='G') {
    trip[i, 'mutType'] <- "A:T to C:G"
  }
}

You can just use Add-Computer, there is a parameter for "-NewName"

Example: Add-Computer -DomainName MYLAB.Local -ComputerName TARGETCOMPUTER -newname NewTARGETCOMPUTER

You might want to check also the parameter "-OPTIONS"

timedelta accepts minus(-) time values. so it could be simple as below

import datetime

enter = datetime.time(hour=1, minute=30)
exit = datetime.time(hour=2, minute=0)
duration = datetime.timedelta(hours=exit.hour-enter.hour, minutes=exit.minute-enter.minute)

# duration = datetime.timedelta(hours=1, minutes=-30)

result

>>> duration
datetime.timedelta(seconds=1800)

Following Code authenticates from LDAP using pure Java JNDI. The Principle is:-

1. First Lookup the user using a admin or DN user.
2. The user object needs to be passed to LDAP again with the user credential
3. No Exception means - Authenticated Successfully. Else Authentication Failed.

Code Snippet

public static boolean authenticateJndi(String username, String password) throws Exception{
    Properties props = new Properties();
    props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
    props.put(Context.PROVIDER_URL, "ldap://LDAPSERVER:PORT");
    props.put(Context.SECURITY_PRINCIPAL, "uid=adminuser,ou=special users,o=xx.com");//adminuser - User with special priviledge, dn user
    props.put(Context.SECURITY_CREDENTIALS, "adminpassword");//dn user password


    InitialDirContext context = new InitialDirContext(props);

    SearchControls ctrls = new SearchControls();
    ctrls.setReturningAttributes(new String[] { "givenName", "sn","memberOf" });
    ctrls.setSearchScope(SearchControls.SUBTREE_SCOPE);

    NamingEnumeration<javax.naming.directory.SearchResult> answers = context.search("o=xx.com", "(uid=" + username + ")", ctrls);
    javax.naming.directory.SearchResult result = answers.nextElement();

    String user = result.getNameInNamespace();

    try {
        props = new Properties();
        props.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");

        props.put(Context.SECURITY_PRINCIPAL, user);
        props.put(Context.SECURITY_CREDENTIALS, password);

   context = new InitialDirContext(props);

        return false;
    }
    return true;

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

OPcache replaces APC

Because OPcache is designed to replace the APC module, it is not possible to run them in parallel in PHP. This is fine for caching PHP opcode as neither affects how you write code.

However it means that if you are currently using APC to store other data (through the apc_store() function) you will not be able to do that if you decide to use OPCache.

You will need to use another library such as either APCu or Yac which both store data in shared PHP memory, or switch to use something like memcached, which stores data in memory in a separate process to PHP.

Also, OPcache has no equivalent of the upload progress meter present in APC. Instead you should use the Session Upload Progress.

Settings for OPcache

The documentation for OPcache can be found here with all of the configuration options listed here. The recommended settings are:

; Sets how much memory to use
opcache.memory_consumption=128

;Sets how much memory should be used by OPcache for storing internal strings 
;(e.g. classnames and the files they are contained in)
opcache.interned_strings_buffer=8

; The maximum number of files OPcache will cache
opcache.max_accelerated_files=4000

;How often (in seconds) to check file timestamps for changes to the shared
;memory storage allocation.
opcache.revalidate_freq=60

;If enabled, a fast shutdown sequence is used for the accelerated code
;The fast shutdown sequence doesn't free each allocated block, but lets
;the Zend Engine Memory Manager do the work.
opcache.fast_shutdown=1

;Enables the OPcache for the CLI version of PHP.
opcache.enable_cli=1

If you use any library or code that uses code annotations you must enable save comments:

opcache.save_comments=1

If disabled, all PHPDoc comments are dropped from the code to reduce the size of the optimized code. Disabling "Doc Comments" may break some existing applications and frameworks (e.g. Doctrine, ZF2, PHPUnit)

You should be able to use the /quiet or /qn options with msiexec to perform a silent install.

MSI packages export public properties, which you can set with the PROPERTY=value syntax on the end of the msiexec parameters.

For example, this command installs a package with no UI and no reboot, with a log and two properties:

msiexec /i c:\path\to\package.msi /quiet /qn /norestart /log c:\path\to\install.log PROPERTY1=value1 PROPERTY2=value2

You can read the options for msiexec by just running it with no options from Start -> Run.

git reset HEAD <file1> <file2> ...

remove the specified files from the next commit

Fast and quick solution:

lsof -n -i4TCP:8080

PID is the second field. Then, kill that process:

kill -9 PID

Less fast but permanent solution

1. Go to /usr/local/bin/ (Can use command+shift+g in finder)

2. Make a file named stop. Paste the below code in it:

#!/bin/bash
touch temp.text
lsof -n -i4TCP:$1 | awk '{print $2}' > temp.text
pidToStop=`(sed '2q;d' temp.text)`
> temp.text
if [[ -n $pidToStop ]]
then
kill -9 $pidToStop
echo "Congrates!! $1 is stopped."
else
echo "Sorry nothing running on above port"
fi
rm temp.text

3. Save this file.
4. Make the file executable chmod 755 stop
5. Now, go to terminal and write stop 8888 (or any port)

I like to have my music, movie, and picture files named a certain way. When I download files from the internet, they usually don’t follow my naming convention. I found myself manually renaming each file to fit my style. This got old realy fast, so I decided to write a program to do it for me.

This program can convert the filename to all lowercase, replace strings in the filename with whatever you want, and trim any number of characters from the front or back of the filename.

The program's source code is also available.

It's a reserved keyword (like return, filter, function, break).

Reference

Also, as per Section 7.6.4 of Bruce Payette's Powershell in Action:

But what happens when you want a script to exit from within a function defined in that script? ... To make this easier, Powershell has the exit keyword.

Of course, as other have pointed out, it's not hard to do what you want by wrapping exit in a function:

PS C:\> function ex{exit}
PS C:\> new-alias ^D ex

I found the solution for this problem, you don't have to delete the global.asax, as it contains some valuable info for your proyect to run smoothly, instead have a look at your controller's name, in my case, my controller was named something as MyController.cs and in the global.asax it's trying to reference a Home Controller.

Look for this lines in the global asax

routes.MapRoute(
   "Default", // Route name
   "{controller}/{action}/{id}", // URL with parameters
   new { controller = "Home", action = "Index", id = UrlParameter.Optional } 

in my case i had to get like this to work

    new { controller = "My", action = "Index", id = UrlParameter.Optional }

as header

AUTH=$(echo -ne "$BASIC_AUTH_USER:$BASIC_AUTH_PASSWORD" | base64 --wrap 0)

curl \
  --header "Content-Type: application/json" \
  --header "Authorization: Basic $AUTH" \
  --request POST \
  --data  '{"key1":"value1", "key2":"value2"}' \
  https://example.com/

I had buildToolsVersion "27.0.1", upgrading it to 27.0.2 fixed the issue.

Also, my android support deps were at version 27.0.2 so they were not aligned to the buildToolsVersion

Agree with Subir Kumar Sao and Faiz.

This answer on super user I think is a better answer. From https://superuser.com/a/573761/67952

"But since you asked for a way without using Before and After, you can use:

Type=idle

which as man systemd.service explains

Behavior of idle is very similar to simple; however, actual execution of the service program is delayed until all active jobs are dispatched. This may be used to avoid interleaving of output of shell services with the status output on the console. Note that this type is useful only to improve console output, it is not useful as a general unit ordering tool, and the effect of this service type is subject to a 5s time-out, after which the service program is invoked anyway. "

To make sed catch from stdin , instead of from a file, you should use -e.

Like this:

curl -k -u admin:admin https://$HOSTNAME:9070/api/tm/3.8/status/$HOSTNAME/statistics/traffic_ips/trafc_ip/ | sed -e 's/["{}]//g' |sed -e 's/[]]//g' |sed -e 's/[\[]//g' |awk  'BEGIN{FS=":"} {print $4}'

remember password needs to be set further even after restarting mysql as below

SET PASSWORD = PASSWORD('root');

First off, this is one of those things that slaps me in the face with surprise: renaming of a column requires creating an entirely new table and copying the data from the old table to the new table...

The GUI I've landed on to do SQLite operations is Base. It's got a nifty Log window that shows all the commands that have been executed. Doing a rename of a column via Base populates the log window with the necessary commands:

These can then be easily copied and pasted where you might need them. For me, that's into an ActiveAndroid migration file. A nice touch, as well, is that the copied data only includes the SQLite commands, not the timestamps, etc.

Hopefully, that saves some people time.

There are couple of ways to initialize the const members inside the class..

Definition of const member in general, needs initialization of the variable too..

1) Inside the class , if you want to initialize the const the syntax is like this

static const int a = 10; //at declaration

2) Second way can be

class A
{
  static const int a; //declaration
};

const int A::a = 10; //defining the static member outside the class

3) Well if you don't want to initialize at declaration, then the other way is to through constructor, the variable needs to be initialized in the initialization list(not in the body of the constructor). It has to be like this

class A
{
  const int b;
  A(int c) : b(c) {} //const member initialized in initialization list
};

You can try this it will recursively find all key values in a json object and constructs as a map . You can simply get which key you want from the Map .

public static Map<String,String> parse(JSONObject json , Map<String,String> out) throws JSONException{
    Iterator<String> keys = json.keys();
    while(keys.hasNext()){
        String key = keys.next();
        String val = null;
        try{
             JSONObject value = json.getJSONObject(key);
             parse(value,out);
        }catch(Exception e){
            val = json.getString(key);
        }

        if(val != null){
            out.put(key,val);
        }
    }
    return out;
}

 public static void main(String[] args) throws JSONException {

    String json = "{'ipinfo': {'ip_address': '131.208.128.15','ip_type': 'Mapped','Location': {'continent': 'north america','latitude': 30.1,'longitude': -81.714,'CountryData': {'country': 'united states','country_code': 'us'},'region': 'southeast','StateData': {'state': 'florida','state_code': 'fl'},'CityData': {'city': 'fleming island','postal_code': '32003','time_zone': -5}}}}";

    JSONObject object = new JSONObject(json);

    JSONObject info = object.getJSONObject("ipinfo");

    Map<String,String> out = new HashMap<String, String>();

    parse(info,out);

    String latitude = out.get("latitude");
    String longitude = out.get("longitude");
    String city = out.get("city");
    String state = out.get("state");
    String country = out.get("country");
    String postal = out.get("postal_code");

    System.out.println("Latitude : " + latitude + " LongiTude : " + longitude + " City : "+city + " State : "+ state + " Country : "+country+" postal "+postal);

    System.out.println("ALL VALUE " + out);

}

Output:

    Latitude : 30.1 LongiTude : -81.714 City : fleming island State : florida Country : united states postal 32003
ALL VALUE {region=southeast, ip_type=Mapped, state_code=fl, state=florida, country_code=us, city=fleming island, country=united states, time_zone=-5, ip_address=131.208.128.15, postal_code=32003, continent=north america, longitude=-81.714, latitude=30.1}

If you have a loop of buttons like me you can try something like this

var buttonTags:[Int:String]? // can be [Int:Any]
let myArray = [0:"a",1:"b"]
for (index,value) in myArray {

     let button = // Create a button

     buttonTags?[index] = myArray[index]
     button.tag = index
     button.addTarget(self, action: #selector(buttonAction(_:)), for: .touchDown)

}
@objc func buttonAction(_ sender:UIButton) {

    let myString = buttonTags[sender.tag]

}

>>> a = ()
>>> type(a)
<type 'tuple'>
>>> a = []
>>> type(a)
<type 'list'>
>>> a = {}
>>> type(a)
<type 'dict'>
>>> a =  ['Stem', 'constitute', 'Sedge', 'Eflux', 'Whim', 'Intrigue'] 
>>> a.sort()
>>> a
['Eflux', 'Intrigue', 'Sedge', 'Stem', 'Whim', 'constitute']
>>> 

The page at http://www.askapache.com/htaccess/apache-speed-cache-control.html suggests using something like this:

Add Cache-Control Headers

This goes in your root .htaccess file but if you have access to httpd.conf that is better.

This code uses the FilesMatch directive and the Header directive to add Cache-Control Headers to certain files.

# 480 weeks
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$">
Header set Cache-Control "max-age=290304000, public"
</FilesMatch>

Use two periods before /, example:

../style.css

You can also use extremely small numbers for your radius'.

<corners 
  android:bottomRightRadius="0.1dp" android:bottomLeftRadius="2dp" 
 android:topLeftRadius="2dp" android:topRightRadius="0.1dp" />

Try using input arrays:

<form action="try.php" method="post">
    <div id="events_wrapper">
        <div id="sub_events">
            <input type="text" name="firstname[]" />                                       
        </div>
    </div>
    <input type="button" id="add_another_event" name="add_another_event" value="Add Another" />
    <input type="submit" name="submit" value="submit" />
</form>

and add this script and jQuery, using foreach() to retrieve the data being $_POST'ed:

<script>                                                                                    
    $(document).ready(function(){
        $("#add_another_event").click(function(){
        var $address = $('#sub_events');
        var num = $('.clonedAddress').length; // there are 5 children inside each address so the prevCloned address * 5 + original
        var newNum = num + 1;
        var newElem = $address.clone().attr('id', 'address' + newNum).addClass('clonedAddress');

        //set all div id's and the input id's
        newElem.children('div').each (function (i) {
            this.id = 'input' + (newNum*5 + i);
        });

        newElem.find('input').each (function () {
            this.id = this.id + newNum;
            this.name = this.name + newNum;
        });

        if (num > 0) {
            $('.clonedAddress:last').after(newElem);
        } else {
            $address.after(newElem);
        }

        $('#btnDel').removeAttr('disabled');
        });

        $("#remove").click(function(){

        });

    });
</script>

Just in case you are (for whatever reason) unable to use curl nor file_get_contents, you can work around:

$img = imagecreatefrompng('...');
ob_start();
imagepng($img);
$bin = ob_get_clean();
$b64 = base64_encode($bin);

Configuration files in python

There are several ways to do this depending on the file format required.

ConfigParser [.ini format]

I would use the standard configparser approach unless there were compelling reasons to use a different format.

Write a file like so:

# python 2.x
# from ConfigParser import SafeConfigParser
# config = SafeConfigParser()

# python 3.x
from configparser import ConfigParser
config = ConfigParser()

config.read('config.ini')
config.add_section('main')
config.set('main', 'key1', 'value1')
config.set('main', 'key2', 'value2')
config.set('main', 'key3', 'value3')

with open('config.ini', 'w') as f:
    config.write(f)

The file format is very simple with sections marked out in square brackets:

[main]
key1 = value1
key2 = value2
key3 = value3

Values can be extracted from the file like so:

# python 2.x
# from ConfigParser import SafeConfigParser
# config = SafeConfigParser()

# python 3.x
from configparser import ConfigParser
config = ConfigParser()

config.read('config.ini')

print config.get('main', 'key1') # -> "value1"
print config.get('main', 'key2') # -> "value2"
print config.get('main', 'key3') # -> "value3"

# getfloat() raises an exception if the value is not a float
a_float = config.getfloat('main', 'a_float')

# getint() and getboolean() also do this for their respective types
an_int = config.getint('main', 'an_int')

JSON [.json format]

JSON data can be very complex and has the advantage of being highly portable.

Write data to a file:

import json

config = {"key1": "value1", "key2": "value2"}

with open('config1.json', 'w') as f:
    json.dump(config, f)

Read data from a file:

import json

with open('config.json', 'r') as f:
    config = json.load(f)

#edit the data
config['key3'] = 'value3'

#write it back to the file
with open('config.json', 'w') as f:
    json.dump(config, f)

YAML

A basic YAML example is provided in this answer. More details can be found on the pyYAML website.

For ImageButton you can use:

favoriteImageButton.setColorFilter(Color.argb(255, 255, 255, 255)); // White Tint

The function is max. To obtain the first maximum value you should do

[val, idx] = max(a);

val is the maximum value and idx is its index.

If your html link is like this:

<a class ="linkClass" href="https://stackoverflow.com/"> Stack Overflow</a>

Then you can access the href in jquery as given below (there is no need to use "a" in href for this)

$(".linkClass").on("click",accesshref);

function accesshref()
 {
 var url = $(".linkClass").attr("href");
 //OR
 var url = $(this).attr("href");
}

sed expression needs to be quoted

sed -i "s/$oldstring/$newstring/g"

To remove a submodule added using:

git submodule add [email protected]:repos/blah.git lib/blah

Run:

git rm lib/blah

That's it.

For old versions of git (circa ~1.8.5) use:

git submodule deinit lib/blah
git rm lib/blah
git config -f .gitmodules --remove-section submodule.lib/blah

If you know the number of entries ex ante, you should preallocate the space by also providing the index (taking the data example from a different answer):

import pandas as pd
import numpy as np
# we know we're gonna have 5 rows of data
numberOfRows = 5
# create dataframe
df = pd.DataFrame(index=np.arange(0, numberOfRows), columns=('lib', 'qty1', 'qty2') )

# now fill it up row by row
for x in np.arange(0, numberOfRows):
    #loc or iloc both work here since the index is natural numbers
    df.loc[x] = [np.random.randint(-1,1) for n in range(3)]
In[23]: df
Out[23]: 
   lib  qty1  qty2
0   -1    -1    -1
1    0     0     0
2   -1     0    -1
3    0    -1     0
4   -1     0     0

Speed comparison

In[30]: %timeit tryThis() # function wrapper for this answer
In[31]: %timeit tryOther() # function wrapper without index (see, for example, @fred)
1000 loops, best of 3: 1.23 ms per loop
100 loops, best of 3: 2.31 ms per loop

And - as from the comments - with a size of 6000, the speed difference becomes even larger:

Increasing the size of the array (12) and the number of rows (500) makes the speed difference more striking: 313ms vs 2.29s

I struggled with this one for a long time! (Using VB.NET) Basically you get the row index and column index of the selected cell, and then use that to access the value.

Private Sub LineListDataGrid_SelectedCellsChanged(sender As Object, e As SelectedCellsChangedEventArgs) Handles LineListDataGrid.SelectedCellsChanged

    Dim colInd As Integer = LineListDataGrid.CurrentCell.Column.DisplayIndex

    Dim rowInd As Integer = LineListDataGrid.Items.IndexOf(LineListDataGrid.CurrentItem)

    Dim item As String

    Try
        item = LLDB.LineList.Rows(rowInd)(colInd)
    Catch
        Exit Sub
    End Try

End Sub

End Class

So, you want to use bcrypt? Awesome! However, like other areas of cryptography, you shouldn't be doing it yourself. If you need to worry about anything like managing keys, or storing salts or generating random numbers, you're doing it wrong.

The reason is simple: it's so trivially easy to screw up bcrypt. In fact, if you look at almost every piece of code on this page, you'll notice that it's violating at least one of these common problems.

Face It, Cryptography is hard.

Leave it for the experts. Leave it for people whose job it is to maintain these libraries. If you need to make a decision, you're doing it wrong.

Instead, just use a library. Several exist depending on your requirements.

Libraries

Here is a breakdown of some of the more common APIs.

PHP 5.5 API - (Available for 5.3.7+)

Starting in PHP 5.5, a new API for hashing passwords is being introduced. There is also a shim compatibility library maintained (by me) for 5.3.7+. This has the benefit of being a peer-reviewed and simple to use implementation.

function register($username, $password) {
    $hash = password_hash($password, PASSWORD_BCRYPT);
    save($username, $hash);
}

function login($username, $password) {
    $hash = loadHashByUsername($username);
    if (password_verify($password, $hash)) {
        //login
    } else {
        // failure
    }
}

Really, it's aimed to be extremely simple.

Resources:

• Documentation: on PHP.net
• Compatibility Library: on GitHub
• PHP's RFC: on wiki.php.net

Zend\Crypt\Password\Bcrypt (5.3.2+)

This is another API that's similar to the PHP 5.5 one, and does a similar purpose.

function register($username, $password) {
    $bcrypt = new Zend\Crypt\Password\Bcrypt();
    $hash = $bcrypt->create($password);
    save($user, $hash);
}

function login($username, $password) {
    $hash = loadHashByUsername($username);
    $bcrypt = new Zend\Crypt\Password\Bcrypt();
    if ($bcrypt->verify($password, $hash)) {
        //login
    } else {
        // failure
    }
}

Resources:

• Documentation: on Zend
• Blog Post: Password Hashing With Zend Crypt

PasswordLib

This is a slightly different approach to password hashing. Rather than simply supporting bcrypt, PasswordLib supports a large number of hashing algorithms. It's mainly useful in contexts where you need to support compatibility with legacy and disparate systems that may be outside of your control. It supports a large number of hashing algorithms. And is supported 5.3.2+

function register($username, $password) {
    $lib = new PasswordLib\PasswordLib();
    $hash = $lib->createPasswordHash($password, '$2y$', array('cost' => 12));
    save($user, $hash);
}

function login($username, $password) {
    $hash = loadHashByUsername($username);
    $lib = new PasswordLib\PasswordLib();
    if ($lib->verifyPasswordHash($password, $hash)) {
        //login
    } else {
        // failure
    }
}

References:

• Source Code / Documentation: GitHub

PHPASS

This is a layer that does support bcrypt, but also supports a fairly strong algorithm that's useful if you do not have access to PHP >= 5.3.2... It actually supports PHP 3.0+ (although not with bcrypt).

function register($username, $password) {
    $phpass = new PasswordHash(12, false);
    $hash = $phpass->HashPassword($password);
    save($user, $hash);
}

function login($username, $password) {
    $hash = loadHashByUsername($username);
    $phpass = new PasswordHash(12, false);
    if ($phpass->CheckPassword($password, $hash)) {
        //login
    } else {
        // failure
    }
}

About BCrypt

If you notice, every one of these libraries returns a single string. That's because of how BCrypt works internally. And there are a TON of answers about that. Here are a selection that I've written, that I won't copy/paste here, but link to:

• Fundamental Difference Between Hashing And Encryption Algorithms - Explaining the terminology and some basic information about them.
• About reversing hashes without rainbow tables - Basically why we should use bcrypt in the first place...
• Storing bcrypt Hashes - basically why is the salt and algorithm included in the hash result.
• How to update the cost of bcrypt hashes - basically how to choose and then maintain the cost of the bcrypt hash.
• How to hash long passwords with bcrypt - explaining the 72 character password limit of bcrypt.
• How bcrypt uses salts
• Best practices of salting and peppering passwords - Basically, don't use a "pepper"
• Migrating old md5 passwords to bcrypt

Wrap Up

There are many different choices. Which you choose is up to you. However, I would HIGHLY recommend that you use one of the above libraries for handling this for you.

Again, if you're using crypt() directly, you're probably doing something wrong. If your code is using hash() (or md5() or sha1()) directly, you're almost definitely doing something wrong.

Just use a library...

find ./someDir -name "*.php" -o -name "*.html" | tar -cf my_archive -T -

XmlDocument is great for developers who are familiar with the XML DOM object model. It's been around for a while, and more or less corresponds to a W3C standard. It supports manual navigation as well as XPath node selection.

XDocument powers the LINQ to XML feature in .NET 3.5. It makes heavy use of IEnumerable<> and can be easier to work with in straight C#.

Both document models require you to load the entire document into memory (unlike XmlReader for example).

There is no 100% solution to delete browser cookies.

The problem is that cookies are uniquely identified by not just by their key "name" but also their "domain" and "path".

Without knowing the "domain" and "path" of a cookie, you cannot reliably delete it. This information is not available through JavaScript's document.cookie. It's not available through the HTTP Cookie header either!

However, if you know the name, path and domain of a cookie, then you can clear it by setting an empty cookie with an expiry date in the past, for example:

function clearCookie(name, domain, path){
    var domain = domain || document.domain;
    var path = path || "/";
    document.cookie = name + "=; expires=" + +new Date + "; domain=" + domain + "; path=" + path;
};

 let date = new Date();
 let dd = date.getDate();//day of month

 let mm = date.getMonth();// month
 let yyyy = date.getFullYear();//day of week
 if (dd < 10) {//if less then 10 add a leading zero
     dd = "0" + dd;
   }
 if (mm < 10) {
    mm = "0" + mm;//if less then 10 add a leading zero
  }

Just remember set method to POST in options. Here is my code

var options = {
    url: 'http://www.example.com',
    method: 'POST', // Don't forget this line
    headers: {
        'Content-Type': 'application/x-www-form-urlencoded',
        'X-MicrosoftAjax': 'Delta=true', // blah, blah, blah...
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36',
    },
    form: {
        'key-1':'value-1',
        'key-2':'value-2',
        ...
    }
};

//console.log('options:', options);

// Create request to get data
request(options, (err, response, body) => {
    if (err) {
        //console.log(err);
    } else {
        console.log('body:', body);
    }
});

Your tables should have as immediate children just tbody and thead elements, with the rows within*. So, amend the HTML to be:

<table border="1" width="100%" id="test">
  <tbody>
    <tr>
     <td>
      <table border="1" width="100%">
        <tbody>
          <tr>
            <td>table 2</td>
          </tr>
        </tbody>
      </table>
     </td>
    </tr> 
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
    <tr><td>table 1</td></tr>
  </tbody>
</table>

Then amend your selector slightly to this:

#test > tbody > tr:last-child { background:#ff0000; }

See it in action here. That makes use of the child selector, which:

...separates two selectors and matches only those elements matched by the second selector that are direct children of elements matched by the first.

So, you are targeting only direct children of tbody elements that are themselves direct children of your #test table.

Alternative solution

The above is the neatest solution, as you don't need to over-ride any styles. The alternative would be to stick with your current set-up, and over-ride the background style for the inner table, like this:

#test tr:last-child { background:#ff0000; }
#test table tr:last-child { background:transparent; }

* It's not mandatory but most (all?) browsers will add these in, so it's best to make it explicit. As @BoltClock states in the comments:

...it's now set in stone in HTML5, so for a browser to be compliant it basically must behave this way.

Try this method.

public static Type GetType(string typeName)
{
    var type = Type.GetType(typeName);
    if (type != null) return type;
    foreach (var a in AppDomain.CurrentDomain.GetAssemblies())
    {
        type = a.GetType(typeName);
        if (type != null)
            return type;
    }
    return null;
}

From a software tester's perspective

#pragma once is shorter than an include guard, less error prone, supported by most compilers, and some say that it compiles faster (which is not true [any longer]).

But I still suggest you go with standard #ifndef include guards.

Why #ifndef?

Consider a contrived class hierarchy like this where each of the classes A, B, and C lives inside its own file:

a.h

#ifndef A_H
#define A_H

class A {
public:
  // some virtual functions
};

#endif

b.h

#ifndef B_H
#define B_H

#include "a.h"

class B : public A {
public:
  // some functions
};

#endif

c.h

#ifndef C_H
#define C_H

#include "b.h"

class C : public B {
public:
  // some functions
};

#endif

Now let's assume you are writing tests for your classes and you need to simulate the behaviour of the really complex class B. One way to do this would be to write a mock class using for example google mock and put it inside a directory mocks/b.h. Note, that the class name hasn't changed but it's only stored inside a different directory. But what's most important is that the include guard is named exactly the same as in the original file b.h.

mocks/b.h

#ifndef B_H
#define B_H

#include "a.h"
#include "gmock/gmock.h"

class B : public A {
public:
  // some mocks functions
  MOCK_METHOD0(SomeMethod, void());
};

#endif

What's the benefit?

With this approach you can mock the behaviour of class B without touching the original class or telling C about it. All you have to do is put the directory mocks/ in the include path of your complier.

Why can't this be done with #pragma once?

If you would have used #pragma once, you would get a name clash because it cannot protect you from defining the class B twice, once the original one and once the mocked version.

What you have is on the right track.

def dosomething( thelist ):
    for element in thelist:
        print element

dosomething( ['1','2','3'] )
alist = ['red','green','blue']
dosomething( alist )  

Produces the output:

1
2
3
red
green
blue

A couple of things to note given your comment above: unlike in C-family languages, you often don't need to bother with tracking the index while iterating over a list, unless the index itself is important. If you really do need the index, though, you can use enumerate(list) to get index,element pairs, rather than doing the x in range(len(thelist)) dance.

For a massive speed increase, use NumPy's where function.

Setup

Create a two-column DataFrame with 100,000 rows with some zeros.

df = pd.DataFrame(np.random.randint(0,3, (100000,2)), columns=list('ab'))

Fast solution with numpy.where

df['b'] = np.where(df.a.values == 0, np.nan, df.b.values)

Timings

%timeit df['b'] = np.where(df.a.values == 0, np.nan, df.b.values)
685 µs ± 6.4 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

%timeit df.loc[df['a'] == 0, 'b'] = np.nan
3.11 ms ± 17.2 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

Numpy's where is about 4x faster

They are used in the linking stage. .a files are statically linked, and .so files are sort-of linked, so that the library is needed whenever you run the exe.

You can find where they are stored by looking at any of the lib directories... /usr/lib and /lib have most of them, and there is also the LIBRARY_PATH environment variable.

You can use the df.reindex() function in pandas. df is

                      Net  Upper   Lower  Mid  Zsore
Answer option                                      
More than once a day  0%  0.22%  -0.12%    2     65
Once a day            0%  0.32%  -0.19%    3     45
Several times a week  2%  2.45%   1.10%    4     78
Once a week           1%  1.63%  -0.40%    6     65

define an list of column names

cols = df.columns.tolist()
cols
Out[13]: ['Net', 'Upper', 'Lower', 'Mid', 'Zsore']

move the column name to wherever you want

cols.insert(0, cols.pop(cols.index('Mid')))
cols
Out[16]: ['Mid', 'Net', 'Upper', 'Lower', 'Zsore']

then use df.reindex() function to reorder

df = df.reindex(columns= cols)

out put is: df

                      Mid  Upper   Lower Net  Zsore
Answer option                                      
More than once a day    2  0.22%  -0.12%  0%     65
Once a day              3  0.32%  -0.19%  0%     45
Several times a week    4  2.45%   1.10%  2%     78
Once a week             6  1.63%  -0.40%  1%     65

this is a simple code I just wrote to solve this, without removing the header row (first one).

var Tbl = document.getElementById('tblId');
while(Tbl.childNodes.length>2){Tbl.removeChild(Tbl.lastChild);}

Hope it works for you!!.

other solution

$template="-----start-------{Value:This is a test 123}------end-------"
$text="-----start-------Hello World------end-------"

$text | ConvertFrom-String -TemplateContent $template

Note that the variables @fname or @ext can be simply concatenated. This:

forfiles /S /M *.pdf /C "CMD /C REN @path @fname_old.@ext"

renames all PDF files to "filename_old.pdf"

How about sapply (not really necessary for this simple case):

newData<- sapply(data, function(x) x^2)

Yes, it is possible.

try:
   ...
except FirstException:
   handle_first_one()

except SecondException:
   handle_second_one()

except (ThirdException, FourthException, FifthException) as e:
   handle_either_of_3rd_4th_or_5th()

except Exception:
   handle_all_other_exceptions()

See: http://docs.python.org/tutorial/errors.html

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)
