An example for a sample "GET" request is given below.

let urlString = "YOUR_GET_URL"
let yourURL = URL(string: urlstring)
let dataTask = URLSession.shared.dataTask(with: yourURL) { (data, response, error) in
do {
    let json = try JSONSerialization.jsonObject(with: data!, options: .mutableContainers)
    print("json --- \(json)")
    }catch let err {
    print("err---\(err.localizedDescription)")
    }
   }
dataTask.resume()

A more complete link to the list of differences is on the Octave's FAQ. In theory, all code that runs in Matlab should run in Octave and Octave developers treat incompatibility with Matlab as bugs. So the answer to your first question is yes in theory. Of course, all software has bugs, neither Octave or Matlab (yes, Matlab too) are safe from them. You can report them and someone will try to fix them

Octave also has extra features, most of them are extra syntax which in my opinion make the code more readable and more sense, specially if you are used to other programming languagues.

But there's more to Octave than just the monetary cost. Octave is free also in the sense of freedom, it's libre, but I don't think this is the place to rant about software freedom.

I do image processing in Octave only and find that the image package suits my needs. I don't know, however, what will be yours. So my answer to if it's worth the cost is no, but certainly others will disagree.

Even once you fixed the mis-cased if and improper indentation in your code, it wouldn't work as you probably expected. To check a string against a set of strings, use in. Here's how you'd do it (and note that if is all lowercase and that the code within the if block is indented one level).

One approach:

if answer in ['y', 'Y', 'yes', 'Yes', 'YES']:
    print("this will do the calculation")

Another:

if answer.lower() in ['y', 'yes']:
    print("this will do the calculation")

Since iOS 11, you can use the native framework called PDFKit for displaying and manipulating PDFs.

After importing PDFKit, you should initialize a PDFView with a local or a remote URL and display it in your view.

if let url = Bundle.main.url(forResource: "example", withExtension: "pdf") {
    let pdfView = PDFView(frame: view.frame)
    pdfView.document = PDFDocument(url: url)
    view.addSubview(pdfView)
}

Read more about PDFKit in the Apple Developer documentation.

yes, I know, I'm too late (as always). Here is my piece of code (based on the reply of mk2). Maybe this helps someone:

std::vector<std::string> find_serial_ports()
{
 std::vector<std::string> ports;
    std::filesystem::path kdr_path{"/proc/tty/drivers"};
    if (std::filesystem::exists(kdr_path))
    {
        std::ifstream ifile(kdr_path.generic_string());
        std::string line;
        std::vector<std::string> prefixes;
        while (std::getline(ifile, line))
        {
            std::vector<std::string> items;
            auto it = line.find_first_not_of(' ');
            while (it != std::string::npos)
            {

                auto it2 = line.substr(it).find_first_of(' ');
                if (it2 == std::string::npos)
                {
                    items.push_back(line.substr(it));
                    break;
                }
                it2 += it;
                items.push_back(line.substr(it, it2 - it));
                it = it2 + line.substr(it2).find_first_not_of(' ');
            }
            if (items.size() >= 5)
            {
                if (items[4] == "serial" && items[0].find("serial") != std::string::npos)
                {
                    prefixes.emplace_back(items[1]);
                }
            }
        }
        ifile.close();
        for (auto& p: std::filesystem::directory_iterator("/dev"))
        {
            for (const auto& pf : prefixes)
            {
                auto dev_path = p.path().generic_string();
                if (dev_path.size() >= pf.size() && std::equal(dev_path.begin(), dev_path.begin() + pf.size(), pf.begin()))
                {
                    ports.emplace_back(dev_path);
                }
            }
        }
    }
    return ports;
}

At the beginning with the usepackage definitions include:

\usepackage{placeins}

And before and after add:

\FloatBarrier
\begin{table}[h]
    \begin{tabular}{llll}
      .... 
    \end{tabular}
\end{table}
\FloatBarrier

This places the table exactly where you want in the text.

The listings package is quite nice and very flexible (e.g. different sizes for comments and code).

One way is to make the classes use a static initializers... I don't think these are inherited (it won't work if they are):

public class Dog extends Animal{

static
{
   Animal a = new Dog();
   //add a to the List
}

It requires you to add this code to all of the classes involved. But it avoids having a big ugly loop somewhere, testing every class searching for children of Animal.

You could also just call to_a after each_byte or even better String#bytes

=> 'hello world'.each_byte.to_a
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

=> 'hello world'.bytes
=> [104, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

For Java, I highly recommend Core Java. It's a large tome (or two large tomes), but I've found it to be one of the best references on Java I've read.

Project Euler has a number of interesting mathematics problems that could provide great material for a beginning programmer to cut her teeth on. The problems begin easy and increase in difficulty and the web is full of sample solutions in various programming languages.

You can use the .tostring() method with datetime format specifiers to format to whatever you need:

The following tables are store WooCommerce products database :

• wp_posts -

  The core of the WordPress data is the posts. It is stored a post_type like product or variable_product.

• wp_postmeta-

  Each post features information called the meta data and it is stored in the wp_postmeta. Some plugins may add their own information to this table like WooCommerce plugin store product_id of product in wp_postmeta table.

Product categories, subcategories stored in this table :

• wp_terms
• wp_termmeta
• wp_term_taxonomy
• wp_term_relationships
• wp_woocommerce_termmeta

following Query Return a list of product categories

SELECT wp_terms.* 
    FROM wp_terms 
    LEFT JOIN wp_term_taxonomy ON wp_terms.term_id = wp_term_taxonomy.term_id
    WHERE wp_term_taxonomy.taxonomy = 'product_cat';

I was getting similar error while creating web-app in eclipse and resolved the problem just by cleaning (deleting all files from) and rebuilding the maven repository

if($(".myClass")[0] != undefined){
  // it exists
}else{
  // does not exist
}

I know its late to post, but I use the site for my own reference and so I wanted to put an answer here for myself to reference in the future too. I hope you (and others) find it helpful.

Lets pretend a bunch of super Einstein experts designed our database. Our super perfect database has 3 tables, and the following relationships defined between them:

TblA 1:M TblB
TblB 1:M TblC

Notice there is no relationship between TblA and TblC

In most scenarios such a simple database is easy to navigate but in commercial databases it is usually impossible to be able to tell at the design stage all the possible uses and combination of uses for data, tables, and even whole databases, especially as systems get built upon and other systems get integrated or switched around or out. This simple fact has spawned a whole industry built on top of databases called Business Intelligence. But I digress...

In the above case, the structure is so simple to understand that its easy to see you can join from TblA, through to B, and through to C and vice versa to get at what you need. It also very vaguely highlights some of the problems with doing it. Now expand this simple chain to 10 or 20 or 50 relationships long. Now all of a sudden you start to envision a need for exactly your scenario. In simple terms, a join from A to C or vice versa or A to F or B to Z or whatever as our system grows.

There are many ways this can indeed be done. The one mentioned above being the most popular, that is driving through all the links. The major problem is that its very slow. And gets progressively slower the more tables you add to the chain, the more those tables grow, and the further you want to go through it.

Solution 1: Look for a common link. It must be there if you taught of a reason to join A to C. If it is not obvious, create a relationship and then join on it. i.e. To join A through B through C there must be some commonality or your join would either produce zero results or a massive number or results (Cartesian product). If you know this commonality, simply add the needed columns to A and C and link them directly.

The rule for relationships is that they simply must have a reason to exist. Nothing more. If you can find a good reason to link from A to C then do it. But you must ensure your reason is not redundant (i.e. its already handled in some other way).

Now a word of warning. There are some pitfalls. But I don't do a good job of explaining them so I will refer you to my source instead of talking about it here. But remember, this is getting into some heavy stuff, so this video about fan and chasm traps is really only a starting point. You can join without relationships. But I advise watching this video first as this goes beyond what most people learn in college and well into the territory of the BI and SAP guys. These guys, while they can program, their day job is to specialise in exactly this kind of thing. How to get massive amounts of data to talk to each other and make sense.

This video is one of the better videos I have come across on the subject. And it's worth looking over some of his other videos. I learned a lot from him.

Or simply:

PRINT SUBSTRING(@SQL_InsertQuery, 1, 8000)
PRINT SUBSTRING(@SQL_InsertQuery, 8001, 16000)

Using function in typescript

openWindow(){
    //you may choose to deduct some value from current screen size
    let height = window.screen.availHeight-100;
    let width = window.screen.availWidth-150;
    window.open("http://your_url",`width=${width},height=${height}`);
}

EDIT: previous answer was backwards of what you wanted. Use str_replace. replace <br> with \n

echo str_replace('<br>', "\n", $var1);

<?php

function takes_array($input)

{

    echo "$input[0] + $input[1] = ", $input[0]+$input[1];

}

?>

This will replace all the characters except alphanumeric

replaceAll("[^A-Za-z0-9]","");

There some issues with pow method:

1. We can replace (y & 1) == 0; with y % 2 == 0
   bitwise operations always are faster.

Your code always decrements y and performs extra multiplication, including the cases when y is even. It's better to put this part into else clause.

public static long pow(long x, int y) {
        long result = 1;
        while (y > 0) {
            if ((y & 1) == 0) {
                x *= x;
                y >>>= 1;
            } else {
                result *= x;
                y--;
            }
        }
        return result;
    }

Fastest method?

There are three ways. For the speed seekers I recommend 'Method 2'

Method 1

Given by this answer

text = 'abcdefg'
new = list(text)
new[6] = 'W'
''.join(new)

Which is pretty slow compared to 'Method 2'

timeit.timeit("text = 'abcdefg'; s = list(text); s[6] = 'W'; ''.join(s)", number=1000000)
1.0411581993103027

Method 2 (FAST METHOD)

Given by this answer

text = 'abcdefg'
text = text[:1] + 'Z' + text[2:]

Which is much faster:

timeit.timeit("text = 'abcdefg'; text = text[:1] + 'Z' + text[2:]", number=1000000)
0.34651994705200195

Method 3:

Byte array:

timeit.timeit("text = 'abcdefg'; s = bytearray(text); s[1] = 'Z'; str(s)", number=1000000)
1.0387420654296875

I would create an object like this:

var options = { 
    size: ["S", "M", "L", "XL", "XXL"],
    color: ["Red", "Blue", "Green", "White", "Black"]
};


alert(Object.keys(options));

To access the keys individualy:

for (var key in options) {
    alert(key);
}

P.S.: when you create a new array object do not use new Array use [] instead.

 import java.util.Scanner;
    public class Print {
        public static void main(String[] args) {
            int row,temp,c,n;
            Scanner s=new Scanner(System.in);
            n=s.nextInt();
            temp = n;
            for ( row = 1 ; row <= n ; row++ )
               {
                  for ( c = 1 ; c < temp ; c++ )
                    System.out.print(" ");

                  temp--;

                  for ( c = 1 ; c <= 2*row - 1 ; c++ )
                      System.out.print("*");

                  System.out.println("");
               }
        }

    }

I wasn't able to reproduce your problem in Google Chrome 4.0, IE8, or Firefox 3.5 using that code. The label and radio button stayed on the same line.

Try putting them both inside a <p> tag, or set the radio button to be inline like The Elite Gentleman suggested.

Here's the quick fix:

If you're using capistrano do this add this to your deploy.rb:

after 'deploy:update_code' do
  run "cd #{release_path}; RAILS_ENV=production rake assets:precompile"
end

cap deploy

Goto:

Registry-> HKEY_LOCAL??_MACHINE-> System-> Cur??rentControlSet-> Servi??ces.

Find the concerned service & delete it. Close regedit. Reboot the PC & Re-install the concerned service. Now the error should be gone.

The recommended way to do this from the current v4 docs is:

$font-size-base: 0.8rem;
$line-height-base: 1;

Be sure to define the variables above the bootstrap css include and they will override the bootstrap.

No need for anything else and this is the cleanest way

It's described quite clearly in the docs https://getbootstrap.com/docs/4.1/content/typography/#global-settings

                  new List<SelectListItem> {

                       new SelectListItem { Value = "1" , Text = "Option B" },
                       new SelectListItem { Value = "2" , Text = "Option C" }
                    },
                  new { @class="myselect"})

I hope it helps Somebody. Thanks

The only real way is to have a container around your image and use overflow:hidden:

HTML

<div class="container"><img src="ckk.jpg" /></div>

CSS

.container {
    width: 300px;
    height: 200px;
    display: block;
    position: relative;
    overflow: hidden;
}

.container img {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
}

It's a pain in CSS to do what you want and center the image, there is a quick fix in jquery such as:

var conHeight = $(".container").height();
var imgHeight = $(".container img").height();
var gap = (imgHeight - conHeight) / 2;
$(".container img").css("margin-top", -gap);

I generally install Apache + PHP + MySQL by-hand, not using any package like those you're talking about.

It's a bit more work, yes; but knowing how to install and configure your environment is great -- and useful.

The first time, you'll need maybe half a day or a day to configure those. But, at least, you'll know how to do so.

And the next times, things will be far more easy, and you'll need less time.

Else, you might want to take a look at Zend Server -- which is another package that bundles Apache + PHP + MySQL.

Or, as an alternative, don't use Windows.

If your production servers are running Linux, why not run Linux on your development machine?

And if you don't want to (or cannot) install Linux on your computer, use a Virtual Machine.

(first post - so it may not be clean)

This is my fix for OS X 11.6, Maven-based Netbeans 8.2 program. Up to now my app is 100% Netbeans - no tweaking (just a few shell escapes for the impossible!).

Having tried most all of the answers here and elsewhere to no avail, I returned to the art of "use what works".

The top answer here (olivier-refalo thanx) looked like the right place to start but didn't help.

Looking at other projects which did work, I noticed some minor differences in the manifest lines:

1. addClasspath, classpathPrefix were absent (deleted them)
2. mainClass was missing the "com." (used the NB -> Project Properties->Run->Main Class->Browse to specify)

Not sure why (I am only 3 months into java) or how, but can only say this worked.

Here is just the modified manifest block used:

    <manifest>
        <mainClass>mypackage.MyClass</mainClass>
    </manifest>

You can have a datetime picker when using matInput with type datetime-local like so:

  <mat-form-field>
    <input matInput type="datetime-local" placeholder="start date">
  </mat-form-field>

You can click on each part of the placeholder to set the day, month, year, hours,minutes and whether its AM or PM.

Sometime this error also occur when you change the order of Component Function while passing to connect.

Incorrect Order:

export default connect(mapDispatchToProps, mapStateToProps)(TodoList);

Correct Order:

export default connect(mapStateToProps,mapDispatchToProps)(TodoList);

Another option is to run the two inserts separately, leaving the FK column null, then running an update to poulate it correctly.

If there is nothing natural stored within the two tables that match from one record to another (likely) then create a temporary GUID column and populate this in your data and insert to both fields. Then you can update with the proper FK and null out the GUIDs.

E.g.:

CREATE TABLE [dbo].[table1] ( 
    [id] [int] IDENTITY(1,1) NOT NULL, 
    [data] [varchar](255) NOT NULL, 
    CONSTRAINT [PK_table1] PRIMARY KEY CLUSTERED ([id] ASC),
    JoinGuid UniqueIdentifier NULL
) 

CREATE TABLE [dbo].[table2] ( 
    [id] [int] IDENTITY(1,1) NOT NULL, 
    [table1_id] [int] NULL, 
    [data] [varchar](255) NOT NULL, 
    CONSTRAINT [PK_table2] PRIMARY KEY CLUSTERED ([id] ASC),
    JoinGuid UniqueIdentifier NULL
) 


INSERT INTO Table1....

INSERT INTO Table2....

UPDATE b
SET table1_id = a.id
FROM Table1 a
JOIN Table2 b on a.JoinGuid = b.JoinGuid
WHERE b.table1_id IS NULL

UPDATE Table1 SET JoinGuid = NULL
UPDATE Table2 SET JoinGuid = NULL

• Install Node js - https://nodejs.org/en/

• go to folder where you have html file:

  • In CMD, run the command to install http server- npm install http-server -g
  • To load file in the browser run - http-server

• If you have specific html file. Run following command in CMD.- http-server fileName

• by default port is 8080

• Go to your browser and type localhost:8080. Your Application should run there.

• If you want to run on different port: http-server fileName -p 9000

Note : To run your .js file run: node fileName.js

If in your HTML you have an input element with a name or id with a _ like e.g. first_name or more than one _ like e.g. student_first_name and you also have the Javascript code at the bottom of your Web Page and you are sure you are doing everything else right, then those dashes could be what is messing you up.

Having id or name for your input elements resembling the below

<input type="text" id="first_name" name="first_name">

or

<input type="text" id="student_first_name" name="student_first_name">

Then you try make a call like this below in your JavaScript code

var first_name = document.getElementById("first_name").value;

or

var student_first_name = document.getElementById("student_first_name").value;

You are certainly going to have an error like Uncaught TypeError: Cannot read property 'value' of null in Google Chrome and on Internet Explorer too. I did not get to test that with Firefox.

In my case I removed the dashes, in first_name and renamed it to firstname and from student_first_name to studentfirstname

At the end, I was able to resolve that error with my code now looking as follows for HTML and JavaScript.

HTML

<input type="text" id="firstname" name="firstname">

or

<input type="text" id="studentfirstname" name="studentfirstname">

Javascript

var firstname = document.getElementById("firstname").value;

or

var studentfirstname = document.getElementById("studentfirstname").value;

So if it is within your means to rename the HTML and JavaScript code with those dashes, it may help if that is what is ailing your piece of code. In my case that was what was bugging me.

Hope this helps someone stop pulling their hair like I was.

For me, what solved the problem was to do a git clone of my project and run (as usual):

npm install

This guide explains in detail how to deploy Spring Boot app on Tomcat:
http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#howto-create-a-deployable-war-file

Essentially I needed to add following class:

public class WebInitializer extends SpringBootServletInitializer {   
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(App.class);
    }    
}

Also I added following property to POM:

<properties>        
    <start-class>mypackage.App</start-class>
</properties>

Many answer above are correct but same time convoluted with other aspects of authN/authZ. What actually resolves the exception in question is this line:

services.AddScheme<YourAuthenticationOptions, YourAuthenticationHandler>(YourAuthenticationSchemeName, options =>
    {
        options.YourProperty = yourValue;
    })

I wish that I could just comment on yojimbo87's answer to post this, but I don't have enough reputation to comment yet. It was pointed out that this relative path only works from the root:

        window.location.href = "/{controller}/{action}/{params}";

Just wanted to confirm that you can use @Url.Content to provide the absolute path:

function DeleteJob() {
    if (confirm("Do you really want to delete selected job/s?"))
        window.location.href = '@Url.Content("~/{controller}/{action}/{params}")';
    else
        return false;
}

I came up with dead-simple bash script. Thanks to jq's author.

#!/bin/bash
set -e

curl -L -s "$PACKAGE_JSON_URL" | jq  -r '.releases | keys | .[]' | sort -V

Update:

• Add sorting by version number.
• Add -L to follow redirects.

Here is an undocumented way to get an Application (which is a Context) from anywhere in the UI thread. It relies on the hidden static method ActivityThread.currentApplication(). It should work at least on Android 4.x.

try {
    final Class<?> activityThreadClass =
            Class.forName("android.app.ActivityThread");
    final Method method = activityThreadClass.getMethod("currentApplication");
    return (Application) method.invoke(null, (Object[]) null);
} catch (final ClassNotFoundException e) {
    // handle exception
} catch (final NoSuchMethodException e) {
    // handle exception
} catch (final IllegalArgumentException e) {
    // handle exception
} catch (final IllegalAccessException e) {
    // handle exception
} catch (final InvocationTargetException e) {
    // handle exception
}

Note that it is possible for this method to return null, e.g. when you call the method outside of the UI thread, or the application is not bound to the thread.

It is still better to use @RohitGhatol's solution if you can change the Application code.

Date, SimpleDateFormat and whatever classes are required on the I/O side of things (there are many possibilities).

Simply call jQuery's toggleClass() on the i element contained within your a element(s) to toggle either the plus and minus icons:

...click(function() {
    $(this).find('i').toggleClass('fa-minus-circle fa-plus-circle');
});

Note that this assumes that a class of fa-plus-circle is added to your i element by default.

JSFiddle demo.

What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles

By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.

You should try changing the value of -Xmx and -Xms.

I was having the same problem, the mysql service was starting but not the apache service, the main problem about that is one of your virtual hosts isn't config. correctly, all i did was deleted the virtual host that i created "D:\wamp\bin\apache\apache2.4.23\conf\extra\httpd-vhosts, restarted all services apache service started working correctly and so i just went to localhost and added a virtual host automatically and so it worked!!

You can use negative integers with the slicing operator for that. Here's an example using the python CLI interpreter:

>>> a = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
>>> a[-9:]
[4, 5, 6, 7, 8, 9, 10, 11, 12]

the important line is a[-9:]

Adding to @StriplingWarrior's answer about bit flags in enums, there's an easy convention you can use in hexadecimal for counting upwards through the bit shifts. Use the sequence 1-2-4-8, move one column to the left, and repeat.

[Flags]
enum Scenery
{
  Trees   = 0x001, // 000000000001
  Grass   = 0x002, // 000000000010
  Flowers = 0x004, // 000000000100
  Cactus  = 0x008, // 000000001000
  Birds   = 0x010, // 000000010000
  Bushes  = 0x020, // 000000100000
  Shrubs  = 0x040, // 000001000000
  Trails  = 0x080, // 000010000000
  Ferns   = 0x100, // 000100000000
  Rocks   = 0x200, // 001000000000
  Animals = 0x400, // 010000000000
  Moss    = 0x800, // 100000000000
}

Scan down starting with the right column and notice the pattern 1-2-4-8 (shift) 1-2-4-8 (shift) ...

To answer the original question, I second @Sahuagin's suggestion to use hexadecimal literals. If you're working with binary numbers often enough for this to be a concern, it's worth your while to get the hang of hexadecimal.

If you need to see binary numbers in source code, I suggest adding comments with binary literals like I have above.

You can set it as a no title bar theme in the activity's xml in the AndroidManifest

    <activity 
        android:name=".AnActivity"
        android:label="@string/a_string"
        android:theme="@android:style/Theme.NoTitleBar">
    </activity>

If you're using bash version > 4.0, you can exploit shopt -s globstar to make short work of this:

shopt -s globstar; tar -czvf deploy.tar.gz **/Alice*.yml **/Bob*.json

this will add all .yml files that starts with Alice from any sub-directory and add all .json files that starts with Bob from any sub-directory.

If the html content overflow a single viewport, this worked for me using only javascript:

document.getElementsByTagName('body')[0].scrollTop = 0;

Regards,

I recommend adding the following line after the export to PDF:

ThisWorkbook.Sheets("Sheet1").Select

(where eg. Sheet1 is the single sheet you want to be active afterwards)

Leaving multiple sheets in a selected state may cause problems executing some code. (eg. unprotect doesn't function properly when multiple sheets are actively selected.)

Was following the documentations - Apache Log4j2 Configuratoin and Apache Log4j2 Maven in configuring log4j2 with yaml. As per the documentation, the following maven dependencies are required:

  <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.8.1</version>
  </dependency>
  <dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.8.1</version>
  </dependency>

and

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-yaml</artifactId>
    <version>2.8.6</version>
</dependency>

Just adding these didn't pick the configuration and always gave error. The way of debugging configuration by adding -Dorg.apache.logging.log4j.simplelog.StatusLogger.level=TRACE helped in seeing the logs. Later had to download the source using Maven and debugging helped in understanding the depended classes of log4j2. They are listed in org.apache.logging.log4j.core.config.yaml.YamlConfigurationFactory:

com.fasterxml.jackson.databind.ObjectMapper
com.fasterxml.jackson.databind.JsonNode
com.fasterxml.jackson.core.JsonParser
com.fasterxml.jackson.dataformat.yaml.YAMLFactory

Adding dependency mapping for jackson-dataformat-yaml will not have the first two classes. Hence, add the jackson-databind dependency to get yaml configuration working:

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.8.6</version>
</dependency>

You may add the version by referring to the Test Dependencies section of log4j-api version item from MVN Repository. E.g. for 2.8.1 version of log4j-api, refer this link and locate the jackson-databind version.

Moreover, you can use the below Java code to check if the classes are available in the classpath:

System.out.println(ClassLoader.getSystemResource("log4j2.yml")); //Check if file is available in CP
ClassLoader cl = Thread.currentThread().getContextClassLoader(); //Code as in log4j2 API. Version: 2.8.1
 String [] classes = {"com.fasterxml.jackson.databind.ObjectMapper",
 "com.fasterxml.jackson.databind.JsonNode",
 "com.fasterxml.jackson.core.JsonParser",
 "com.fasterxml.jackson.dataformat.yaml.YAMLFactory"};

 for(String className : classes) {
     cl.loadClass(className);
 }

Your regex won't match anything, as it is. You definitely need to remove the quotes -- the "/" characters are sufficient.

/^\s+$/ is checking whether the string is ALL whitespace:

• ^ matches the start of the string.
• \s+ means at least 1, possibly more, spaces.
• $ matches the end of the string.

Try replacing the regex with /\s/ (and no quotes)

Try the following:

df[df['Col2'].isnull()]

CSS relates to visual styling and not behaviour, so the answer is no really.

You could however either use javascript to modify the behaviour or change the styling of the span in question so that it doesn't have the pointy finger, underline, etc. Styling it like that will still leave it clickable.

Even better, change your markup so that it reflects what you want it to do.

This is so called file local variables, that are understood by Emacs and set correspondingly. See corresponding section in Emacs manual - you can define them either in header or in footer of file

You can use Drawable instead of Uri.

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

This would work.

Seems like having "Build Automatically" under the Project menu ought to take care of all of this. It does for Java.

More clear query, targeting Studio sql queries is :

SELECT text  FROM sys.dm_exec_sessions es
  INNER JOIN sys.dm_exec_connections ec
      ON es.session_id = ec.session_id
  CROSS APPLY sys.dm_exec_sql_text(ec.most_recent_sql_handle) 
  where program_name like '%Query'

ModelName::find($id, ['name', 'surname']);

You want a parameter source:

Set<Integer> ids = ...;

MapSqlParameterSource parameters = new MapSqlParameterSource();
parameters.addValue("ids", ids);

List<Foo> foo = getJdbcTemplate().query("SELECT * FROM foo WHERE a IN (:ids)",
     parameters, getRowMapper());

This only works if getJdbcTemplate() returns an instance of type NamedParameterJdbcTemplate

Although this is an old question, it seems like many still encounter it - we spent days on end tracking this down ourselves.

In the OAuth2 spec, "invalid_grant" is sort of a catch-all for all errors related to invalid/expired/revoked tokens (auth grant or refresh token).

For us, the problem was two-fold:

1. User has actively revoked access to our app
   Makes sense, but get this: 12 hours after revocation, Google stops sending the error message in their response: “error_description” : “Token has been revoked.”
   It's rather misleading because you'll assume that the error message is there at all times which is not the case. You can check whether your app still has access at the apps permission page.

2. User has reset/recovered their Google password
   In December 2015, Google changed their default behaviour so that password resets for non-Google Apps users would automatically revoke all the user's apps refresh tokens. On revocation, the error message follows the same rule as the case before, so you'll only get the "error_description" in the first 12 hours. There doesn't seem to be any way of knowing whether the user manually revoked access (intentful) or it happened because of a password reset (side-effect).

Apart from those, there's a myriad of other potential causes that could trigger the error:

3. Server clock/time is out of sync
4. Not authorized for offline access
5. Throttled by Google
6. Using expired refresh tokens
7. User has been inactive for 6 months
8. Use service worker email instead of client ID
9. Too many access tokens in short time
10. Client SDK might be outdated
11. Incorrect/incomplete refresh token

I've written a short article summarizing each item with some debugging guidance to help find the culprit. Hope it helps.

 SELECT * FROM ALL_source WHERE UPPER(text) LIKE '%BLAH%'

EDIT Adding additional info:

 SELECT * FROM DBA_source WHERE UPPER(text) LIKE '%BLAH%'

The difference is dba_source will have the text of all stored objects. All_source will have the text of all stored objects accessible by the user performing the query. Oracle Database Reference 11g Release 2 (11.2)

Another difference is that you may not have access to dba_source.

Please read this official blog entry on Google developer blog: http://android-developers.blogspot.be/2011/03/identifying-app-installations.html

Conclusion For the vast majority of applications, the requirement is to identify a particular installation, not a physical device. Fortunately, doing so is straightforward.

There are many good reasons for avoiding the attempt to identify a particular device. For those who want to try, the best approach is probably the use of ANDROID_ID on anything reasonably modern, with some fallback heuristics for legacy devices

You're very close. What you need to remember is when you're calling a method from another class you need to tell the compiler where to find that method.

So, instead of simply calling addWord("someWord"), you will need to initialise an instance of the WordList class (e.g. WordList list = new WordList();), and then call the method using that (i.e. list.addWord("someWord");.

However, your code at the moment will still throw an error there, because that would be trying to call a non-static method from a static one. So, you could either make addWord() static, or change the methods in the Words class so that they're not static.

My bad with the above paragraph - however you might want to reconsider ProcessInput() being a static method - does it really need to be?

This is achieved through URL rewriting, not through URL obfuscating, which can't be done.

Another way to do this, as has been mentioned is by changing the hashtag, with

window.location.hash = "/2131/"

@Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)

Given annotation worked for me. Can have a try

For Example :-

     public class Parent{
            @Id
            @GeneratedValue(strategy=GenerationType.AUTO)
            @Column(name="cct_id")
            private Integer cct_id;
            @OneToMany(cascade=CascadeType.REMOVE, fetch=FetchType.EAGER,mappedBy="clinicalCareTeam", orphanRemoval=true)
            @Cascade(org.hibernate.annotations.CascadeType.DELETE_ORPHAN)
            private List<Child> childs;
        }
            public class Child{
            @ManyToOne(fetch=FetchType.EAGER)
            @JoinColumn(name="cct_id")
            private Parent parent;
    }

You can use WScript.Arguments to access the arguments passed to your script.

Calling the script:

cscript.exe test.vbs "C:\temp\"

Inside your script:

Set File = FSO.OpenTextFile(WScript.Arguments(0) &"\test.txt", 2, True)

Don't forget to check if there actually has been an argument passed to your script. You can do so by checking the Count property:

if WScript.Arguments.Count = 0 then
    WScript.Echo "Missing parameters"
end if

If your script is over after you close the file then there is no need to set the variables to Nothing. The resources will be cleaned up automatically when the cscript.exe process terminates. Setting a variable to Nothing usually is only necessary if you explicitly want to free resources during the execution of your script. In that case, you would set variables which contain a reference to a COM object to Nothing, which would release the COM object before your script terminates. This is just a short answer to your bonus question, you will find more information in these related questions:

With the new animation API that was introduced in Android 3.0 (Honeycomb) it is very simple to create such animations.

Sliding a View down by a distance:

view.animate().translationY(distance);

You can later slide the View back to its original position like this:

view.animate().translationY(0);

You can also easily combine multiple animations. The following animation will slide a View down by its height and fade it in at the same time:

// Prepare the View for the animation
view.setVisibility(View.VISIBLE);
view.setAlpha(0.0f);

// Start the animation
view.animate()
    .translationY(view.getHeight())
    .alpha(1.0f)
    .setListener(null);

You can then fade the View back out and slide it back to its original position. We also set an AnimatorListener so we can set the visibility of the View back to GONE once the animation is finished:

view.animate()
    .translationY(0)
    .alpha(0.0f)
    .setListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationEnd(Animator animation) {
            super.onAnimationEnd(animation);
            view.setVisibility(View.GONE);
        }
    });

You can simply do this:

.test {
  position: -webkit-sticky; /* Safari */
  position: sticky;
  right: 0;
}

It seems that your project is written in Python < 3. This is because the file() builtin function is removed in Python 3. Try using Python 2to3 tool or edit the erroneous file yourself.

EDIT: BTW, the project page clearly mentions that

Gunicorn requires Python 2.x >= 2.5. Python 3.x support is planned.

your string is NOT a valid json to start with.

a valid json will be,

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

if you do a json_decode, it will yield,

stdClass Object
(
    [area] => Array
        (
            [0] => stdClass Object
                (
                    [area] => kothrud
                )

            [1] => stdClass Object
                (
                    [area] => katraj
                )

        )

)

Update: to use

$string = '

{
    "area": [
        {
            "area": "kothrud"
        },
        {
            "area": "katraj"
        }
    ]
}

';
            $area = json_decode($string, true);

            foreach($area['area'] as $i => $v)
            {
                echo $v['area'].'<br/>';
            }

Output:

kothrud
katraj

I came here because I'm new with python and lazy so I was searching an example to create a list of 2 lists, after a while a realized the topic here could be wrong... this is a code to create a list of lists:

listoflists = []
for i in range(0,2):
    sublist = []
    for j in range(0,10)
        sublist.append((i,j))
    listoflists.append(sublist)
print listoflists

this the output [ [(0, 0), (0, 1), (0, 2), (0, 3), (0, 4), (0, 5), (0, 6), (0, 7), (0, 8), (0, 9)], [(1, 0), (1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (1, 7), (1, 8), (1, 9)] ]

The problem with your code seems to be you are creating a tuple with your list and you get the reference to the list instead of a copy. That I guess should fall under a tuple topic...

Drop the quotes:

List<Object> bugs = JsonPath.read(githubIssues, "$..labels[?(@.name==bug)]");

If you need to loop inside a directory recursively for a particular kind of file, use the below command, which filters all the files of doc file type

$fileNames = Get-ChildItem -Path $scriptPath -Recurse -Include *.doc

If you need to do the filteration on multiple types, use the below command.

$fileNames = Get-ChildItem -Path $scriptPath -Recurse -Include *.doc,*.pdf

Now $fileNames variable act as an array from which you can loop and apply your business logic.

After a lot of time spent trying all these technique in a Dialog, I finally had this idea : attach the theme to the Dialog itself and not to the TextInputLayout.

<style name="AppTheme_Dialog" parent="Theme.AppCompat.Dialog">

    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorWhite</item>
    <item name="colorAccent">@color/colorPrimary</item>

</style>

inside onCreate :

public class myDialog extends Dialog {

private Activity activity;
private someVars;

public PopupFeedBack(Activity activity){
    super(activity, R.style.AppTheme_Dialog);
    setContentView(R.layout.myView);
    ....}}

cheers :)

yield is just like return - it returns whatever you tell it to (as a generator). The difference is that the next time you call the generator, execution starts from the last call to the yield statement. Unlike return, the stack frame is not cleaned up when a yield occurs, however control is transferred back to the caller, so its state will resume the next time the function is called.

In the case of your code, the function get_child_candidates is acting like an iterator so that when you extend your list, it adds one element at a time to the new list.

list.extend calls an iterator until it's exhausted. In the case of the code sample you posted, it would be much clearer to just return a tuple and append that to the list.

    Log.e(TAG, "connectToWifi: Missing network configuration.");
}
return null;

If you have an array that contains objects, you need to make a copy of that array without touching its internal pointer, and you need all the objects to be cloned (so that you're not modifying the originals when you make changes to the copied array), use this.

The trick to not touching the array's internal pointer is to make sure you're working with a copy of the array, and not the original array (or a reference to it), so using a function parameter will get the job done (thus, this is a function that takes in an array).

Note that you will still need to implement __clone() on your objects if you'd like their properties to also be cloned.

This function works for any type of array (including mixed type).

function array_clone($array) {
    return array_map(function($element) {
        return ((is_array($element))
            ? array_clone($element)
            : ((is_object($element))
                ? clone $element
                : $element
            )
        );
    }, $array);
}

Check : git branch -a

If you are getting only one branch. Then do below steps.

• Step 1 : git config --list
• Step 2 : git config --unset remote.origin.fetch
• Step 3 : git config --add remote.origin.fetch +refs/heads/*:refs/remotes/origin/*

DriverManager is a fairly old way of doing things. The better way is to get a DataSource, either by looking one up that your app server container already configured for you:

Context context = new InitialContext();
DataSource dataSource = (DataSource) context.lookup("java:comp/env/jdbc/myDB");

or instantiating and configuring one from your database driver directly:

MysqlDataSource dataSource = new MysqlDataSource();
dataSource.setUser("scott");
dataSource.setPassword("tiger");
dataSource.setServerName("myDBHost.example.org");

and then obtain connections from it, same as above:

Connection conn = dataSource.getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT ID FROM USERS");
...
rs.close();
stmt.close();
conn.close();

You may try this way. just use a function to get your object

def get_object(self, id):
    try:
        return Comment.objects.get(pk=id)
    except Comment.DoesNotExist:
        return False

You can just call

python /path/to/filename.py

To get data types of all columns:

describe table_name

or just a single column:

describe table_name column_name

Assuming the key is contained inside the <appSettings> node:

ConfigurationSettings.AppSettings["theKey"];

As for "writing" - put simply, dont.

The web.config is not designed for that, if you're going to be changing a value constantly, put it in a static helper class.

My favorite way to do is by using behavior subject or event emitter (almost the same) in my service to control all my subcomponent.

Using angular cli, run ng g s to create a new service then use a BehaviorSubject or EventEmitter

export Class myService {
#all the stuff that must exist

myString: string[] = [];
contactChange : BehaviorSubject<string[]> = new BehaviorSubject(this.myString);

   getContacts(newContacts) {
     // get your data from a webservices & when you done simply next the value 
    this.contactChange.next(newContacts);
   }
}

When you do that every component using your service as a provider will be aware of the change. Simply subscribe to the result like you do with eventEmitter ;)

export Class myComp {
#all the stuff that exists like @Component + constructor using (private myService: myService)

this.myService.contactChange.subscribe((contacts) => {
     this.contactList += contacts; //run everytime next is called
  }
}

A really simple way to suppress the warning is to add a property in the .csproj file:

<Project>
    <PropertyGroup>
        ...     
        <!--disable missing comment warning-->
        <NoWarn>$(NoWarn);1591</NoWarn>
    </PropertyGroup>
...

void is a reserved JavaScript keyword. It evaluates the expression and always returns undefined.

Also lazy is useful without cyclic dependencies, as in the following code:

abstract class X {
  val x: String
  println ("x is "+x.length)
}

object Y extends X { val x = "Hello" }
Y

Accessing Y will now throw null pointer exception, because x is not yet initialized. The following, however, works fine:

abstract class X {
  val x: String
  println ("x is "+x.length)
}

object Y extends X { lazy val x = "Hello" }
Y

EDIT: the following will also work:

object Y extends { val x = "Hello" } with X 

This is called an "early initializer". See this SO question for more details.

Set the CSS position: relative; on the box. This causes all absolute positions of objects inside to be relative to the corners of that box. Then set the following CSS on the "Bet 5 days ago" line:

position: absolute;
bottom: 0;
right: 0;

If you need to space the text farther away from the edge, you could change 0 to 2px or similar.

You can just do

print()

to get an empty line.

This is a common problem, so here's a relatively thorough illustration.

For non-unicode strings (i.e. those without u prefix like u'\xc4pple'), one must decode from the native encoding (iso8859-1/latin1, unless modified with the enigmatic sys.setdefaultencoding function) to unicode, then encode to a character set that can display the characters you wish, in this case I'd recommend UTF-8.

First, here is a handy utility function that'll help illuminate the patterns of Python 2.7 string and unicode:

>>> def tell_me_about(s): return (type(s), s)

A plain string

>>> v = "\xC4pple" # iso-8859-1 aka latin1 encoded string

>>> tell_me_about(v)
(<type 'str'>, '\xc4pple')

>>> v
'\xc4pple'        # representation in memory

>>> print v
?pple             # map the iso-8859-1 in-memory to iso-8859-1 chars
                  # note that '\xc4' has no representation in iso-8859-1, 
                  # so is printed as "?".

Decoding a iso8859-1 string - convert plain string to unicode

>>> uv = v.decode("iso-8859-1")
>>> uv
u'\xc4pple'       # decoding iso-8859-1 becomes unicode, in memory

>>> tell_me_about(uv)
(<type 'unicode'>, u'\xc4pple')

>>> print v.decode("iso-8859-1")
Äpple             # convert unicode to the default character set
                  # (utf-8, based on sys.stdout.encoding)

>>> v.decode('iso-8859-1') == u'\xc4pple'
True              # one could have just used a unicode representation 
                  # from the start

A little more illustration — with “Ä”

>>> u"Ä" == u"\xc4"
True              # the native unicode char and escaped versions are the same

>>> "Ä" == u"\xc4"  
False             # the native unicode char is '\xc3\x84' in latin1

>>> "Ä".decode('utf8') == u"\xc4"
True              # one can decode the string to get unicode

>>> "Ä" == "\xc4"
False             # the native character and the escaped string are
                  # of course not equal ('\xc3\x84' != '\xc4').

Encoding to UTF

>>> u8 = v.decode("iso-8859-1").encode("utf-8")
>>> u8
'\xc3\x84pple'    # convert iso-8859-1 to unicode to utf-8

>>> tell_me_about(u8)
(<type 'str'>, '\xc3\x84pple')

>>> u16 = v.decode('iso-8859-1').encode('utf-16')
>>> tell_me_about(u16)
(<type 'str'>, '\xff\xfe\xc4\x00p\x00p\x00l\x00e\x00')

>>> tell_me_about(u8.decode('utf8'))
(<type 'unicode'>, u'\xc4pple')

>>> tell_me_about(u16.decode('utf16'))
(<type 'unicode'>, u'\xc4pple')

Relationship between unicode and UTF and latin1

>>> print u8
Äpple             # printing utf-8 - because of the encoding we now know
                  # how to print the characters

>>> print u8.decode('utf-8') # printing unicode
Äpple

>>> print u16     # printing 'bytes' of u16
???pple

>>> print u16.decode('utf16')
Äpple             # printing unicode

>>> v == u8
False             # v is a iso8859-1 string; u8 is a utf-8 string

>>> v.decode('iso8859-1') == u8
False             # v.decode(...) returns unicode

>>> u8.decode('utf-8') == v.decode('latin1') == u16.decode('utf-16')
True              # all decode to the same unicode memory representation
                  # (latin1 is iso-8859-1)

Unicode Exceptions

 >>> u8.encode('iso8859-1')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0:
  ordinal not in range(128)

>>> u16.encode('iso8859-1')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0:
  ordinal not in range(128)

>>> v.encode('iso8859-1')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc4 in position 0:
  ordinal not in range(128)

One would get around these by converting from the specific encoding (latin-1, utf8, utf16) to unicode e.g. u8.decode('utf8').encode('latin1').

So perhaps one could draw the following principles and generalizations:

• a type str is a set of bytes, which may have one of a number of encodings such as Latin-1, UTF-8, and UTF-16
• a type unicode is a set of bytes that can be converted to any number of encodings, most commonly UTF-8 and latin-1 (iso8859-1)
• the print command has its own logic for encoding, set to sys.stdout.encoding and defaulting to UTF-8
• One must decode a str to unicode before converting to another encoding.

Of course, all of this changes in Python 3.x.

Hope that is illuminating.

INSERT syntax cannot have WHERE but you can use UPDATE.

The syntax is as follows:

UPDATE table_name

SET column1 = value1, column2 = value2, ...

WHERE condition;

Giving access to the IIS AppPool\YourAppPoolName user may be not enough with IIS default configurations.

In my case, I still had the error HTTP Error 401.3 - Unauthorized after adding the AppPool user and it was fixed only after adding permissions to the IUSR user.

This is necessary because, by default, Anonymous access is done using the IUSR. You can set another specific user, the Application Pool or continue using the IUSR, but don't forget to set the appropriate permissions.

Credits to this answer: HTTP Error 401.3 - Unauthorized

If you have context data along with css and js in your html template. Than you have good option to use pdfjs.

In your code you can use like this.

from django.template.loader import get_template
import pdfkit
from django.conf import settings

context={....}
template = get_template('reports/products.html')
html_string = template.render(context)
pdfkit.from_string(html_string, os.path.join(settings.BASE_DIR, "media", 'products_report-%s.pdf'%(id)))

In your HTML you can link extranal or internal css and js, it will generate best quality of pdf.

Normally, I'd suggest trying the ANSI-92 standard meta tables for something like this but I see now that Oracle doesn't support it.

-- this works against most any other database
SELECT
    * 
FROM 
    INFORMATION_SCHEMA.COLUMNS C 
    INNER JOIN 
        INFORMATION_SCHEMA.TABLES T 
        ON T.TABLE_NAME = C.TABLE_NAME 
WHERE 
    C.COLUMN_NAME = 'columnname'
    AND T.TABLE_NAME = 'tablename'

Instead, it looks like you need to do something like

-- Oracle specific table/column query
SELECT
    * 
FROM
    ALL_TAB_COLUMNS 
WHERE
    TABLE_NAME = 'tablename'
    AND COLUMN_NAME = 'columnname'

I do apologize in that I don't have an Oracle instance to verify the above. If it does not work, please let me know and I will delete this post.

You are also able to do some text manipulation inside the braces:

STRING="./folder/subfolder/file.txt"
echo ${STRING} ${STRING%/*/*}

Result:

./folder/subfolder/file.txt ./folder

or

STRING="This is a string"
echo ${STRING// /_}

Result:

This_is_a_string

You are right in "regular variables" are not needed... But it is more helpful for the debugging and to read a script.

Yes, a table have one or many foreign keys and each foreign keys hava a different parent table.

As amaud576875 said, the \r escape sequence signifies a carriage-return, similar to pressing the Enter key. However, I'm not sure how you get "o world"; you should (and I do) get "my first hello world" and then a new line. Depending on what operating system you're using (I'm using Mac) you might want to use a \n instead of a \r.

Easiest way to clear/reset the text field on click is to clear/reset the scope

<input type="text" class="form-control" ng-model="searchAll" ng-click="clearfunction(this)"/>

In Controller

$scope.clearfunction=function(event){
   event.searchAll=null;
}

import subprocess
string="echo Hello world"
result=subprocess.getoutput(string)
print("result::: ",result)

Here is some information about one more source of the JSESSIONID cookie:

I was just debugging some Java code that runs on a tomcat server. I was not calling request.getSession() explicitly anywhere in my code but I noticed that a JSESSIONID cookie was still being set.

I finally took a look at the generated Java code corresponding to a JSP in the work directory under Tomcat.

It appears that, whether you like it or not, if you invoke a JSP from a servlet, JSESSIONID will get created!

Added: I just found that by adding the following JSP directive:

<%@ page session="false" %>

you can disable the setting of JSESSIONID by a JSP.

in my case it was an error in the storyboard source code, follow these steps:

1. first open your story board as source code
2. search for <connections>
3. remove unwanted connections

For example:

<connections>
    <outlet property="mapPostsView" destination="4EV-NK-Bhn" id="ubM-Z6-mwl"/>
    <outlet property="mapView" destination="kx6-TV-oQg" id="4wY-jv-Ih6"/>
    <outlet property="sidebarButton" destination="6UH-BZ-60q" id="8Yz-5G-HpY"/>
</connections>

As you see, these are connections between your code variables' names and the storyboard layout xml tags ;)

If you call methods in your constructor that subclasses override, it means you are less likely to be referencing variables that don’t exist yet if you divide your initialization logically between the constructor and the method.

Have a look on this sample link http://www.javapractices.com/topic/TopicAction.do?Id=215

see if their duplicate jars or dependencies your adding remove it and your error will be gone: Eg: if you add android:supportv4 jar and also dependency you will get the error so remove the jar error will be gone

INSERT OR REPLACE will replace the other fields to default value.

sqlite> CREATE TABLE Book (
  ID     INTEGER PRIMARY KEY AUTOINCREMENT,
  Name   TEXT,
  TypeID INTEGER,
  Level  INTEGER,
  Seen   INTEGER
);

sqlite> INSERT INTO Book VALUES (1001, 'C++', 10, 10, 0);

sqlite> SELECT * FROM Book;
1001|C++|10|10|0

sqlite> INSERT OR REPLACE INTO Book(ID, Name) VALUES(1001, 'SQLite');

sqlite> SELECT * FROM Book;
1001|SQLite|||

If you want to preserve the other field

• Method 1

sqlite> SELECT * FROM Book;
1001|C++|10|10|0

sqlite> INSERT OR IGNORE INTO Book(ID) VALUES(1001);
sqlite> UPDATE Book SET Name='SQLite' WHERE ID=1001;

sqlite> SELECT * FROM Book;
1001|SQLite|10|10|0

• Method 2

Using UPSERT (syntax was added to SQLite with version 3.24.0 (2018-06-04))

INSERT INTO Book (ID, Name)
  VALUES (1001, 'SQLite')
  ON CONFLICT (ID) DO
  UPDATE SET Name=excluded.Name;

The excluded. prefix equal to the value in VALUES ('SQLite').

Due to the stateless nature of the web, sessions are also an extremely useful way of persisting objects across requests by serialising them and storing them in a session.

A perfect use case of this could be if you need to access regular information across your application, to save additional database calls on each request, this data can be stored in an object and unserialised on each request, like so:

Our reusable, serializable object:

[Serializable]
public class UserProfileSessionData
{
    public int UserId { get; set; }

    public string EmailAddress { get; set; }

    public string FullName { get; set; }
}

Use case:

public class LoginController : Controller {

    [HttpPost]
    public ActionResult Login(LoginModel model)
    {
        if (ModelState.IsValid)
        {
            var profileData = new UserProfileSessionData {
                UserId = model.UserId,
                EmailAddress = model.EmailAddress,
                FullName = model.FullName
            }

            this.Session["UserProfile"] = profileData;
        }
    }

    public ActionResult LoggedInStatusMessage()
    {
        var profileData = this.Session["UserProfile"] as UserProfileSessionData;

        /* From here you could output profileData.FullName to a view and
        save yourself unnecessary database calls */
    }

}

Once this object has been serialised, we can use it across all controllers without needing to create it or query the database for the data contained within it again.

Inject your session object using Dependency Injection

In a ideal world you would 'program to an interface, not implementation' and inject your serializable session object into your controller using your Inversion of Control container of choice, like so (this example uses StructureMap as it's the one I'm most familiar with).

public class WebsiteRegistry : Registry
{
    public WebsiteRegistry()
    {
        this.For<IUserProfileSessionData>().HybridHttpOrThreadLocalScoped().Use(() => GetUserProfileFromSession());   
    }

    public static IUserProfileSessionData GetUserProfileFromSession()
    {
        var session = HttpContext.Current.Session;
        if (session["UserProfile"] != null)
        {
            return session["UserProfile"] as IUserProfileSessionData;
        }

        /* Create new empty session object */
        session["UserProfile"] = new UserProfileSessionData();

        return session["UserProfile"] as IUserProfileSessionData;
    }
}

You would then register this in your Global.asax.cs file.

For those that aren't familiar with injecting session objects, you can find a more in-depth blog post about the subject here.

A word of warning:

It's worth noting that sessions should be kept to a minimum, large sessions can start to cause performance issues.

It's also recommended to not store any sensitive data in them (passwords, etc).

In addition to the orbeckst answer one might also want to shift the subplots down. Here's an MWE in OOP style:

import matplotlib.pyplot as plt

fig = plt.figure()
st = fig.suptitle("suptitle", fontsize="x-large")

ax1 = fig.add_subplot(311)
ax1.plot([1,2,3])
ax1.set_title("ax1")

ax2 = fig.add_subplot(312)
ax2.plot([1,2,3])
ax2.set_title("ax2")

ax3 = fig.add_subplot(313)
ax3.plot([1,2,3])
ax3.set_title("ax3")

fig.tight_layout()

# shift subplots down:
st.set_y(0.95)
fig.subplots_adjust(top=0.85)

fig.savefig("test.png")

gives:

just use \xb0 (in a string); python will convert it automatically

using which.min and which.max :

library(dplyr, warn.conflicts = F)
df %>% 
  group_by(id) %>% 
  slice(c(which.min(stopSequence), which.max(stopSequence)))

#> # A tibble: 6 x 3
#> # Groups:   id [3]
#>      id stopId stopSequence
#>   <dbl> <fct>         <dbl>
#> 1     1 a                 1
#> 2     1 c                 3
#> 3     2 b                 1
#> 4     2 c                 4
#> 5     3 b                 1
#> 6     3 a                 3

benchmark

It is also much faster than the current accepted answer because we find the min and max value by group, instead of sorting the whole stopSequence column.

# create a 100k times longer data frame
df2 <- bind_rows(replicate(1e5, df, F)) 
bench::mark(
  mm =df2 %>% 
    group_by(id) %>% 
    slice(c(which.min(stopSequence), which.max(stopSequence))),
  jeremy = df2 %>%
    group_by(id) %>%
    arrange(stopSequence) %>%
    filter(row_number()==1 | row_number()==n()))

.a are static libraries. If you use code stored inside them, it's taken from them and embedded into your own binary. In Visual Studio, these would be .lib files.

.so are dynamic libraries. If you use code stored inside them, it's not taken and embedded into your own binary. Instead it's just referenced, so the binary will depend on them and the code from the so file is added/loaded at runtime. In Visual Studio/Windows these would be .dll files (with small .lib files containing linking information).

I feel so damn silly. In my case, it turns out my Android Studio had two projects, one was for my React Native app root and the other for /android. If I closed the project and opened the /android project, I could access AVD Manager again.

Should do the trick.

I've built a function that deals with plotting FFT of real signals. The extra bonus in my function relative to the previous answers is that you get the actual amplitude of the signal.

Also, because of the assumption of a real signal, the FFT is symmetric, so we can plot only the positive side of the x-axis:

import matplotlib.pyplot as plt
import numpy as np
import warnings


def fftPlot(sig, dt=None, plot=True):
    # Here it's assumes analytic signal (real signal...) - so only half of the axis is required

    if dt is None:
        dt = 1
        t = np.arange(0, sig.shape[-1])
        xLabel = 'samples'
    else:
        t = np.arange(0, sig.shape[-1]) * dt
        xLabel = 'freq [Hz]'

    if sig.shape[0] % 2 != 0:
        warnings.warn("signal preferred to be even in size, autoFixing it...")
        t = t[0:-1]
        sig = sig[0:-1]

    sigFFT = np.fft.fft(sig) / t.shape[0]  # Divided by size t for coherent magnitude

    freq = np.fft.fftfreq(t.shape[0], d=dt)

    # Plot analytic signal - right half of frequence axis needed only...
    firstNegInd = np.argmax(freq < 0)
    freqAxisPos = freq[0:firstNegInd]
    sigFFTPos = 2 * sigFFT[0:firstNegInd]  # *2 because of magnitude of analytic signal

    if plot:
        plt.figure()
        plt.plot(freqAxisPos, np.abs(sigFFTPos))
        plt.xlabel(xLabel)
        plt.ylabel('mag')
        plt.title('Analytic FFT plot')
        plt.show()

    return sigFFTPos, freqAxisPos


if __name__ == "__main__":
    dt = 1 / 1000

    # Build a signal within Nyquist - the result will be the positive FFT with actual magnitude
    f0 = 200  # [Hz]
    t = np.arange(0, 1 + dt, dt)
    sig = 1 * np.sin(2 * np.pi * f0 * t) + \
        10 * np.sin(2 * np.pi * f0 / 2 * t) + \
        3 * np.sin(2 * np.pi * f0 / 4 * t) +\
        7.5 * np.sin(2 * np.pi * f0 / 5 * t)

    # Result in frequencies
    fftPlot(sig, dt=dt)
    # Result in samples (if the frequencies axis is unknown)
    fftPlot(sig)

In my case, the error disappeared after I rebooted my OS and restarted MariaDB-server. Strange.

I think this is an straight forward answer:

public static IEnumerable<string> Split(this string str, int chunkSize)
    {
        if(string.IsNullOrEmpty(str) || chunkSize<1)
            throw new ArgumentException("String can not be null or empty and chunk size should be greater than zero.");
        var chunkCount = str.Length / chunkSize + (str.Length % chunkSize != 0 ? 1 : 0);
        for (var i = 0; i < chunkCount; i++)
        {
            var startIndex = i * chunkSize;
            if (startIndex + chunkSize >= str.Length)
                yield return str.Substring(startIndex);
            else
                yield return str.Substring(startIndex, chunkSize);
        }
    }

And it covers edge cases.

In the Javascript community, lots of people argue that OOP should not be used because the prototype model does not allow to do a strict and robust OOP natively. However, I don't think that OOP is a matter of langage but rather a matter of architecture.

If you want to use a real strong OOP in Javascript/Node, you can have a look at the full-stack open source framework Danf. It provides all needed features for a strong OOP code (classes, interfaces, inheritance, dependency-injection, ...). It also allows you to use the same classes on both the server (node) and client (browser) sides. Moreover, you can code your own danf modules and share them with anybody thanks to Npm.

The problem, as the Traceback says, comes from the line x[i+1] = x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] ). Let's replace it in its context:

• x is an array equal to [x0 * n], so its length is 1
• you're iterating from 0 to n-2 (n doesn't matter here), and i is the index. In the beginning, everything is ok (here there's no beginning apparently... :( ), but as soon as i + 1 >= len(x) <=> i >= 0, the element x[i+1] doesn't exist. Here, this element doesn't exist since the beginning of the for loop.

To solve this, you must replace x[i+1] = x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] ) by x.append(x[i] + ( t[i+1] - t[i] ) * f( x[i], t[i] )).

If $_SERVER['HTTP_REFERER'] variable doesn't seems to work, then you can either use Google Analytics or AddThis Analytics.

DECLARE @BirthDate datetime, @AgeInMonths int
SET @BirthDate = '10/5/1971'
SET @AgeInMonths                              -- Determine the age in "months old":
    = DATEDIFF(MONTH, @BirthDate, GETDATE())  -- .Get the difference in months
    - CASE WHEN DATEPART(DAY,GETDATE())       -- .If today was the 1st to 4th,
              < DATEPART(DAY,@BirthDate)      --   (or before the birth day of month)
           THEN 1 ELSE 0 END                  --   ... don't count the month.
SELECT @AgeInMonths / 12 as AgeYrs            -- Divide by 12 months to get the age in years
      ,@AgeInMonths % 12 as AgeXtraMonths     -- Get the remainder of dividing by 12 months = extra months
      ,DATEDIFF(DAY                           -- For the extra days, find the difference between, 
               ,DATEADD(MONTH, @AgeInMonths   -- 1. Last Monthly Birthday 
                             , @BirthDate)    --     (if birthdays were celebrated monthly)
               ,GETDATE()) as AgeXtraDays     -- 2. Today's date.

The class java.sql.Date is designed to carry only a date without time, so the conversion result you see is correct for this type. You need to use a java.sql.Timestamp to get a full date with time.

java.util.Date newDate = result.getTimestamp("VALUEDATE");

I don't think SQL Server is case-sensitive, at least not by default.

When I'm querying manually via Management Studio, I mess up case all the time and it cheerfully accepts it:

select cOL1, col2 FrOM taBLeName WheRE ...

Through the original question is not exactly about the locale itself all other locale related questions are referencing to this one. That's why I wanted to clarify the issue here. I used this question as a starting point for my own locale switching code and found out that the method is not exactly correct. It works, but only until any configuration change (e.g. screen rotation) and only in that particular Activity. Playing with a code for a while I have ended up with the following approach:

I have extended android.app.Application and added the following code:

public class MyApplication extends Application
{
    private Locale locale = null;

    @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);
        if (locale != null)
        {
            newConfig.locale = locale;
            Locale.setDefault(locale);
            getBaseContext().getResources().updateConfiguration(newConfig, getBaseContext().getResources().getDisplayMetrics());
        }
    }

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

        SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);

        Configuration config = getBaseContext().getResources().getConfiguration();

        String lang = settings.getString(getString(R.string.pref_locale), "");
        if (! "".equals(lang) && ! config.locale.getLanguage().equals(lang))
        {
            locale = new Locale(lang);
            Locale.setDefault(locale);
            config.locale = locale;
            getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
        }
    }
}

This code ensures that every Activity will have custom locale set and it will not be reset on rotation and other events.

I have also spent a lot of time trying to make the preference change to be applied immediately but didn't succeed: the language changed correctly on Activity restart, but number formats and other locale properties were not applied until full application restart.

Changes to AndroidManifest.xml

Don't forget to add android:configChanges="layoutDirection|locale" to every activity at AndroidManifest, as well as the android:name=".MyApplication" to the <application> element.

You could check out JBoss Tools plugin.

I don't think you can do this with CSS. Instead, at regular 'word lengths' along the string, insert an HTML soft-hyphen:

ACTGATCG­AGCTGAAG­CGCAGTGC­GATGCTTC­GATGATGC­TGACGATG

This will display a hyphen at the end of the line, where it wraps, which may or may not be what you want.

Note Safari seems to wrap the long string in a <textarea> anyway, unlike Firefox.

You can't do it because you can't have control on the manner Chrome opens its windows

The label's information is stored in the ViewState input on postback (keep in mind the server knows nothing of the page outside of the form values posted back, which includes your label's text).. you would have to somehow update that on the client side to know what changed in that label, which I'm guessing would not be worth your time.

I'm not entirely sure what problem you're trying to solve here, but this might give you a few ideas of how to go about it:

You could create a hidden field to go along with your label, and anytime you update your label, you'd update that value as well.. then in the code behind set the Text property of the label to be what was in that hidden field.

Interesting if maddening puzzle...but here's the best I could get:

The data seems to repeat every 8 bytes or so.

import struct
import base64

target = \
r'''Q5YACgAAAABDlgAbAAAAAEOWAC0AAAAAQ5YAPwAAAABDlgdNAAAAAEOWB18AAAAAQ5YH 
[snip.]
ZAAAAABExxniAAAAAETH/rQAAAAARMf/MwAAAABEx/+yAAAAAETIADEAAAAA''' 

data = base64.b64decode(target)

cleaned_data = []
struct_format = ">ff"
for i in range(len(data) // 8):
   cleaned_data.append(struct.unpack_from(struct_format, data, 8*i))

That gives output like the following (a sampling of lines from the first 100 or so):

(300.00030517578125, 0.0)
(300.05975341796875, 241.93943786621094)

(328.34432983398438, 280.55218505859375)

That first number does seem to monotonically increase through the entire set. If you plot it:

import matplotlib.pyplot as plt
f, ax = plt.subplots()
ax.plot(*zip(*cleaned_data))

format = 'hhhh' (possibly with various paddings/directions (e.g. '<hhhh', '<xhhhh') also might be worth a look (again, random lines):

One more difference specific to microsoft sql server is with delete you can use output statement to track what records have been deleted, e.g.:

delete from [SomeTable]
output deleted.Id, deleted.Name

You cannot do this with truncate.

I don't know what qualifies as best but zxing has a qr code generator for java, is actively developed, and is liberally licensed.

The difference lies in the fact that ./gradlew indicates you are using a gradle wrapper. The wrapper is generally part of a project and it facilitates installation of gradle. If you were using gradle without the wrapper you would have to manually install it - for example, on a mac brew install gradle and then invoke gradle using the gradle command. In both cases you are using gradle, but the former is more convenient and ensures version consistency across different machines.

Each Wrapper is tied to a specific version of Gradle, so when you first run one of the commands above for a given Gradle version, it will download the corresponding Gradle distribution and use it to execute the build.

Not only does this mean that you don’t have to manually install Gradle yourself, but you are also sure to use the version of Gradle that the build is designed for. This makes your historical builds more reliable

Read more here - https://docs.gradle.org/current/userguide/gradle_wrapper.html

Also, Udacity has a neat, high level video explaining the concept of the gradle wrapper - https://www.youtube.com/watch?v=1aA949H-shk

Run the following from the command prompt: set Path="C:\Program Files\Java\jdk1.7.0_09\bin" or set PATH="C:\Program Files\Java\jdk1.7.0_09\bin"

I have tried this and it works well.

Suggest you add handling to test if any of the sheets to be renamed already exist:

Sub Test()

Dim ws As Worksheet
Dim ws1 As Worksheet
Dim strErr As String

On Error Resume Next
For Each ws In ActiveWorkbook.Sheets
Set ws1 = Sheets(ws.Name & "_v1")
    If ws1 Is Nothing Then
        ws.Name = ws.Name & "_v1"
    Else
         strErr = strErr & ws.Name & "_v1" & vbNewLine
    End If
Set ws1 = Nothing
Next
On Error GoTo 0

If Len(strErr) > 0 Then MsgBox strErr, vbOKOnly, "these sheets already existed"

End Sub

return RedirectToAction("ProductImageManager","Index", new   { id=id   });

Here is an invalid parameters order, should be an action first
AND
ensure your routing table is correct

You can simply use JavaScripts join() function for that. This would simply look like a.value.join(','). The output would be a string though.

You can simply use Python standard library. Make a shallow copy of the original image as follows:

import copy

original_img = cv2.imread("foo.jpg")
clone_img = copy.copy(original_img)

This expression will match all the image urls -

^(?:http(s)?:\/\/)?[\w.-]+(?:\.[\w\.-]+)+[\w\-\._~:/?#[\]@!\$&'\(\)\*\+,;=.]+(?:png|jpg|jpeg|gif|svg)+$

I just placed a short-cut to the XAMPP control panel in my startup folder. That works just fine on Window 7. Start -> All Programs -> Startup. There is also an option to start XAMPP control panel minimized, that is very useful for getting a clean unobstructed view of your desktop at start-up.**

Using regex and find&replace, you can delete all the lines containing #region without leaving empty lines. Because for some reason Ray's method didn't work on my machine I searched for (.*#region.*\n)|(\n.*#region.*) and left the replace box empty.

That regex ensures that the if #region is found on the first line, the ending newline is deleted, and if it is found on the last line the preceding newline is deleted.

Still, Ray's solution is the better one if it works for you.

Simplest way,

Controller:

[HttpGet("empId={empId}&startDate={startDate}&endDate={endDate}")]
 public IEnumerable<Validate> Get(int empId, string startDate, string endDate){}

Postman Request:

{router}/empId=1&startDate=2020-20-20&endDate=2020-20-20

Learning point: Request exact pattern will be accepted by the Controller.

just for modifying certain property from object collection you could directly use forEach with a collection as follows

collection.forEach(c -> c.setXyz(c.getXyz + "a"))

There is one more stacktrace feature offered by Throwable family - the possibility to manipulate stack trace information.

Standard behavior:

package test.stack.trace;

public class SomeClass {

    public void methodA() {
        methodB();
    }

    public void methodB() {
        methodC();
    }

    public void methodC() {
        throw new RuntimeException();
    }

    public static void main(String[] args) {
        new SomeClass().methodA();
    }
}

Stack trace:

Exception in thread "main" java.lang.RuntimeException
    at test.stack.trace.SomeClass.methodC(SomeClass.java:18)
    at test.stack.trace.SomeClass.methodB(SomeClass.java:13)
    at test.stack.trace.SomeClass.methodA(SomeClass.java:9)
    at test.stack.trace.SomeClass.main(SomeClass.java:27)

Manipulated stack trace:

package test.stack.trace;

public class SomeClass {

    ...

    public void methodC() {
        RuntimeException e = new RuntimeException();
        e.setStackTrace(new StackTraceElement[]{
                new StackTraceElement("OtherClass", "methodX", "String.java", 99),
                new StackTraceElement("OtherClass", "methodY", "String.java", 55)
        });
        throw e;
    }

    public static void main(String[] args) {
        new SomeClass().methodA();
    }
}

Stack trace:

Exception in thread "main" java.lang.RuntimeException
    at OtherClass.methodX(String.java:99)
    at OtherClass.methodY(String.java:55)

Update query may have some issues

$query = "UPDATE anstalld SET mandag = '$mandag', tisdag = '$tisdag', onsdag = '$onsdag', torsdag = '$torsdag', fredag = '$fredag' WHERE namn = '$namn' ";
echo $query;

Please make sure that, your variable not having values with qoutes ( ' ), May be the query is breaking somewhere.

echo the query and try to execute in phpmyadmin itself. Then you can find the issues.

For new Mysql 5.7 for some reason bin commands of Mysql not attached to the shell:

1. Restart the Mac after install.

2. Start Mysql:

   System Preferences > Mysql > Start button

3. Go to Mysql install folder in terminal:

   $ cd /usr/local/mysql/bin/

4. Access to Mysql:

   $ ./mysql -u root -p

and enter the initial password given to the installation.

4. In Mysql terminal change password:

   mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPassword';

df.T.iloc[-1]

df.T.tail(1)

pd.Series(df.values[:, -1], name=df.columns[-1])

Inside of your loop, you have the key, which you can use to retrieve the value from the Map:

for (String key: mss1.keySet()) {
    System.out.println(key + ": " + mss1.get(key));
}

as form the configuration xml it is clear that you are going to use spring based transaction. Please make sure that the import which you are using for @Transactional is "org.springframework.transaction.annotation.Transactional"

in your case it might be "javax.transaction.Transactional"

cheers

Chetan Verma

// file Foo.php
class Foo
{
  static function init() { /* ... */ }
}

Foo::init();

This way, the initialization happens when the class file is included. You can make sure this only happens when necessary (and only once) by using autoloading.

Nope IF is the way to go, what is the problem you have with using it?

BTW your example won't ever get to the third block of code as it and the second block are exactly alike.

Yes, you can.

@supports (-webkit-touch-callout: none) {
  /* CSS specific to iOS devices */ 
}

@supports not (-webkit-touch-callout: none) {
  /* CSS for other than iOS devices */ 
}

YMMV.

It works because only Safari Mobile implements -webkit-touch-callout: https://developer.mozilla.org/en-US/docs/Web/CSS/-webkit-touch-callout

Please note that @supports does not work in IE. IE will skip both of the above @support blocks above. To find out more see https://hacks.mozilla.org/2016/08/using-feature-queries-in-css/. It is recommended to not use @supports not because of this.

What about Chrome or Firefox on iOS? The reality is these are just skins over the WebKit rendering engine. Hence the above works everywhere on iOS as long as iOS policy does not change. See 2.5.6 in App Store Review Guidelines.

Warning: iOS may remove support for this in any new iOS release in the coming years. You SHOULD try a bit harder to not need the above CSS. An earlier version of this answer used -webkit-overflow-scrolling but a new iOS version removed it. As a commenter pointed out, there are other options to choose from: Go to Supported CSS Properties and search for "Safari on iOS".

I did some more work on these extensions - You can find the code here

I wrote some extension methods that extend System.Enum that I use often... I'm not claiming that they are bulletproof, but they have helped... Comments removed...

namespace Enum.Extensions {

    public static class EnumerationExtensions {

        public static bool Has<T>(this System.Enum type, T value) {
            try {
                return (((int)(object)type & (int)(object)value) == (int)(object)value);
            } 
            catch {
                return false;
            }
        }

        public static bool Is<T>(this System.Enum type, T value) {
            try {
                return (int)(object)type == (int)(object)value;
            }
            catch {
                return false;
            }    
        }


        public static T Add<T>(this System.Enum type, T value) {
            try {
                return (T)(object)(((int)(object)type | (int)(object)value));
            }
            catch(Exception ex) {
                throw new ArgumentException(
                    string.Format(
                        "Could not append value from enumerated type '{0}'.",
                        typeof(T).Name
                        ), ex);
            }    
        }


        public static T Remove<T>(this System.Enum type, T value) {
            try {
                return (T)(object)(((int)(object)type & ~(int)(object)value));
            }
            catch (Exception ex) {
                throw new ArgumentException(
                    string.Format(
                        "Could not remove value from enumerated type '{0}'.",
                        typeof(T).Name
                        ), ex);
            }  
        }

    }
}

Then they are used like the following

SomeType value = SomeType.Grapes;
bool isGrapes = value.Is(SomeType.Grapes); //true
bool hasGrapes = value.Has(SomeType.Grapes); //true

value = value.Add(SomeType.Oranges);
value = value.Add(SomeType.Apples);
value = value.Remove(SomeType.Grapes);

bool hasOranges = value.Has(SomeType.Oranges); //true
bool isApples = value.Is(SomeType.Apples); //false
bool hasGrapes = value.Has(SomeType.Grapes); //false

Per the TypeScript 2.3 release notes on "New --downlevelIteration":

for..of statements, Array Destructuring, and Spread elements in Array, Call, and New expressions support Symbol.iterator in ES5/E3 if available when using --downlevelIteration

This is not enabled by default! Add "downlevelIteration": true to your tsconfig.json, or pass --downlevelIteration flag to tsc, to get full iterator support.

With this in place, you can write for (let keyval of myMap) {...} and keyval's type will be automatically inferred.

Why is this turned off by default? According to TypeScript contributor @aluanhaddad,

It is optional because it has a very significant impact on the size of generated code, and potentially on performance, for all uses of iterables (including arrays).

If you can target ES2015 ("target": "es2015" in tsconfig.json or tsc --target ES2015) or later, enabling downlevelIteration is a no-brainer, but if you're targeting ES5/ES3, you might benchmark to ensure iterator support doesn't impact performance (if it does, you might be better off with Array.from conversion or forEach or some other workaround).

You can filter all 'invalid' chars with a custom FilterReader class:

public class InvalidXmlCharacterFilter extends FilterReader {

    protected InvalidXmlCharacterFilter(Reader in) {
        super(in);
    }

    @Override
    public int read(char[] cbuf, int off, int len) throws IOException {
        int read = super.read(cbuf, off, len);
        if (read == -1) return read;

        for (int i = off; i < off + read; i++) {
            if (!XMLChar.isValid(cbuf[i])) cbuf[i] = '?';
        }
        return read;
    }
}

And run it like this:

InputStream fileStream = new FileInputStream(xmlFile);
Reader reader = new BufferedReader(new InputStreamReader(fileStream, charset));
InvalidXmlCharacterFilter filter = new InvalidXmlCharacterFilter(reader);
InputSource is = new InputSource(filter);
xmlReader.parse(is);

Formally, True is a Python built-in constant of bool type.

You can use Boolean operations on bool types (at the interactive python prompt for example) and convert numbers into bool types:

>>> print not True
False
>>> print not False
True
>>> print True or False
True
>>> print True and False
False
>>> a=bool(9)
>>> print a
True
>>> b=bool(0)
>>> print b
False
>>> b=bool(0.000000000000000000000000000000000001)
>>> print b
True

And there are "gotcha's" potentially with what you see and what the Python compiler sees:

>>> n=0
>>> print bool(n)
False
>>> n='0'
>>> print bool(n)
True
>>> n=0.0
>>> print bool(n)
False
>>> n="0.0"
>>> print bool(n)
True

As a hint of how Python stores bool types internally, you can cast bool types to integers and True will come out to be 1 and False 0:

>>> print True+0
1
>>> print True+1
2
>>> print False+0
0
>>> print False+1
1

In fact, Python bool type is a subclass of Python's int type:

>>> type(True)
<type 'bool'>
>>> isinstance(True, int)
True

The more important part of your question is "What is while True?" is 'what is True', and an important corollary: What is false?

First, for every language you are learning, learn what the language considers 'truthy' and 'falsey'. Python considers Truth slightly differently than Perl Truth for example. Other languages have slightly different concepts of true / false. Know what your language considers to be True and False for different operations and flow control to avoid many headaches later!

There are many algorithms where you want to process something until you find what you are looking for. Hence the infinite loop or indefinite loop. Each language tend to have its own idiom for these constructs. Here are common C infinite loops, which also work for Perl:

for(;;) { /* loop until break */ }

/* or */

while (1) {
   return if (function(arg) > 3);
}

The while True: form is common in Python for indefinite loops with some way of breaking out of the loop. Learn Python flow control to understand how you break out of while True loops. Unlike most languages, for example, Python can have an else clause on a loop. There is an example in the last link.

your first try is using declarative pipelines, and the second working one is using scripted pipelines. you need to enclose steps in a steps declaration, and you can't use if as a top-level step in declarative, so you need to wrap it in a script step. here's a working declarative version:

pipeline {
    agent any

    stages {
        stage('test') {
            steps {
                sh 'echo hello'
            }
        }
        stage('test1') {
            steps {
                sh 'echo $TEST'
            }
        }
        stage('test3') {
            steps {
                script {
                    if (env.BRANCH_NAME == 'master') {
                        echo 'I only execute on the master branch'
                    } else {
                        echo 'I execute elsewhere'
                    }
                }
            }
        }
    }
}

you can simplify this and potentially avoid the if statement (as long as you don't need the else) by using "when". See "when directive" at https://jenkins.io/doc/book/pipeline/syntax/. you can also validate jenkinsfiles using the jenkins rest api. it's super sweet. have fun with declarative pipelines in jenkins!

In your "hostname".err file inside the data folder MySQL works on, try to look for a string that starts with:

"A temporary password is generated for roor@localhost "

you can use

less /mysql/data/dir/hostname.err 

then slash command followed by the string you wish to look for

/"A temporary password"

Then press n, to go to the Next result.

In Windows 7, the command is

fsutil hardlink create new-file existing-file

PowerShell finds it without the full path (c:\Windows\system32) or extension (.exe).

Handling database versions is very important part of application development. I assume that you already have class AppDbHelper extending SQLiteOpenHelper. When you extend it you will need to implement onCreate and onUpgrade method.

1. When onCreate and onUpgrade methods called

   • onCreate called when app newly installed.
   • onUpgrade called when app updated.

2. Organizing Database versions I manage versions in a class methods. Create implementation of interface Migration. E.g. For first version create MigrationV1 class, second version create MigrationV1ToV2 (these are my naming convention)

    public interface Migration {
        void run(SQLiteDatabase db);//create tables, alter tables
    }

Example migration:

public class MigrationV1ToV2 implements Migration{
      public void run(SQLiteDatabase db){
        //create new tables
        //alter existing tables(add column, add/remove constraint)
        //etc.
     }
   }

3. Using Migration classes

onCreate: Since onCreate will be called when application freshly installed, we also need to execute all migrations(database version updates). So onCreate will looks like this:

public void onCreate(SQLiteDatabase db){
        Migration mV1=new MigrationV1();
       //put your first database schema in this class
        mV1.run(db);
        Migration mV1ToV2=new MigrationV1ToV2();
        mV1ToV2.run(db);
        //other migration if any
  }

onUpgrade: This method will be called when application is already installed and it is updated to new application version. If application contains any database changes then put all database changes in new Migration class and increment database version.

For example, lets say user has installed application which has database version 1, and now database version is updated to 2(all schema updates kept in MigrationV1ToV2). Now when application upgraded, we need to upgrade database by applying database schema changes in MigrationV1ToV2 like this:

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    if (oldVersion < 2) {
        //means old version is 1
        Migration migration = new MigrationV1ToV2();
        migration.run(db);
    }
    if (oldVersion < 3) {
        //means old version is 2
    }
}

Note: All upgrades (mentioned in onUpgrade) in to database schema should be executed in onCreate

I wanted to expand on the answer that Brian contributed to make this easily usable in other places.

/// <summary>
/// This will add an array of parameters to a SqlCommand. This is used for an IN statement.
/// Use the returned value for the IN part of your SQL call. (i.e. SELECT * FROM table WHERE field IN (returnValue))
/// </summary>
/// <param name="sqlCommand">The SqlCommand object to add parameters to.</param>
/// <param name="array">The array of strings that need to be added as parameters.</param>
/// <param name="paramName">What the parameter should be named.</param>
protected string AddArrayParameters(SqlCommand sqlCommand, string[] array, string paramName)
{
    /* An array cannot be simply added as a parameter to a SqlCommand so we need to loop through things and add it manually. 
     * Each item in the array will end up being it's own SqlParameter so the return value for this must be used as part of the
     * IN statement in the CommandText.
     */
    var parameters = new string[array.Length];
    for (int i = 0; i < array.Length; i++)
    {
        parameters[i] = string.Format("@{0}{1}", paramName, i);
        sqlCommand.Parameters.AddWithValue(parameters[i], array[i]);
    }

    return string.Join(", ", parameters);
}

You can use this new function as follows:

SqlCommand cmd = new SqlCommand();

string ageParameters = AddArrayParameters(cmd, agesArray, "Age");
sql = string.Format("SELECT * FROM TableA WHERE Age IN ({0})", ageParameters);

cmd.CommandText = sql;

public static class Extensions
{
    public static void AddArrayParameters<T>(this SqlCommand cmd, string name, IEnumerable<T> values) 
    { 
        name = name.StartsWith("@") ? name : "@" + name;
        var names = string.Join(", ", values.Select((value, i) => { 
            var paramName = name + i; 
            cmd.Parameters.AddWithValue(paramName, value); 
            return paramName; 
        })); 
        cmd.CommandText = cmd.CommandText.Replace(name, names); 
    }
}

You can then use this extension method as follows:

var ageList = new List<int> { 1, 3, 5, 7, 9, 11 };
var cmd = new SqlCommand();
cmd.CommandText = "SELECT * FROM MyTable WHERE Age IN (@Age)";    
cmd.AddArrayParameters("Age", ageList);

Make sure you set the CommandText before calling AddArrayParameters.

Also make sure your parameter name won't partially match anything else in your statement (i.e. @AgeOfChild)

In our case we are using ToroiseSVN and it seems by default the bin folder is not added to the sourcecontrol. So when updating the website on the production server the bin folder was not added to it, thus resulting in this exception.

To add the bin folder to SVN go to the folder on the hdd and find the bin folder. Right click it and select TortoiseSVN --> Add

Now update the repository to include the newly added files and update the production server next. All should be well now.

Since Java 8 you can use lambdas and achieve shorter code:

File dir = new File(xmlFilesDirectory);
File[] files = dir.listFiles((d, name) -> name.endsWith(".xml"));

MySQL create function syntax:

DELIMITER //

CREATE FUNCTION GETFULLNAME(fname CHAR(250),lname CHAR(250))
    RETURNS CHAR(250)
    BEGIN
        DECLARE fullname CHAR(250);
        SET fullname=CONCAT(fname,' ',lname);
        RETURN fullname;
    END //

DELIMITER ;

Use This Function In Your Query

SELECT a.*,GETFULLNAME(a.fname,a.lname) FROM namedbtbl as a


SELECT GETFULLNAME("Biswarup","Adhikari") as myname;

In Visual Studio 2012 all I had to do was enter:

(localdb)\v11.0

Visual Studio 2015 and Visual Studio 2017 changed to:

(localdb)\MSSQLLocalDB

as the server name when adding a Microsoft SQL Server Data source in:

View/Server Explorer/(Right click) Data Connections/Add Connection

and then the database names were populated. I didn't need to do all the other steps in the accepted answer, although it would be nice if the server name was available automatically in the server name combo box.

You can also browse the LocalDB database names available on your machine using:

View/SQL Server Object Explorer.

There must be more to a Python dictionary than a table lookup on hash(). By brute experimentation I found this hash collision:

>>> hash(1.1)
2040142438
>>> hash(4504.1)
2040142438

Yet it doesn't break the dictionary:

>>> d = { 1.1: 'a', 4504.1: 'b' }
>>> d[1.1]
'a'
>>> d[4504.1]
'b'

Sanity check:

>>> for k,v in d.items(): print(hash(k))
2040142438
2040142438

Possibly there's another lookup level beyond hash() that avoids collisions between dictionary keys. Or maybe dict() uses a different hash.

(By the way, this in Python 2.7.10. Same story in Python 3.4.3 and 3.5.0 with a collision at hash(1.1) == hash(214748749.8).)

Both the Vars() and dict methods will work for the example the OP posted, but they won't work for "loosely" defined objects like:

class foo:
  a = 'foo'
  b = 'bar'

To print all non-callable attributes, you can use the following function:

def printVars(object):
    for i in [v for v in dir(object) if not callable(getattr(object,v))]:
        print '\n%s:' % i
        exec('print object.%s\n\n') % i

Two-stage authentication is not supported with IIS7 Integrated mode. Authentication is now modularized, so rather than IIS performing authentication followed by asp.net performing authentication, it all happens at the same time.

You can either:

1. Change the app domain to be in IIS6 classic mode...
2. Follow this example (old link) of how to fake two-stage authentication with IIS7 integrated mode.
3. Use Helicon Ape and mod_auth to provide basic authentication

Do not define your view globally if u call it from background service.

Like @Maximiliangerhardt said, MiniJson do not have the capability to deserialize properly. I used JsonFx and works like a charm. Works with the []

player[] p = JsonReader.Deserialize<player[]>(serviceData);
Debug.Log(p[0].playerId +" "+ p[0].playerLoc+"--"+ p[1].playerId + " " + p[1].playerLoc+"--"+ p[2].playerId + " " + p[2].playerLoc);

If you plan on using Bootstrap 4 which is required with the angular-ui team's ng-bootstrap that is mentioned in this thread, you'll want to use this instead (NOTE: you don't need to include the JS file):

  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" integrity="sha384-rwoIResjU2yc3z8GV/NPeZWAv56rSmLldC3R/AZzGRnGxQQKnKkoFVhFQhNUwEyJ" crossorigin="anonymous">

You can also reference this locally after running npm install [email protected] --save by pointing to the file in your styles.scss file, assuming you're using SASS:

@import '../../node_modules/bootstrap/dist/css/bootstrap.min.css';

you can do like this :

<?php
    $file = 'your_images.jpg';

    header('Content-Type: image/jpeg');
    header('Content-Length: ' . filesize($file));
    echo file_get_contents($file);
?>

Alternatively, you can also parse a standard markdown document (without code blocks per se) on the fly by the markdownreports package.

You do not need to create data frame from vector of strings, if you want to replace some characters in it. Regular expressions is good choice for it as it has been already mentioned by @Andrie and @Dirk Eddelbuettel.

Pay attention, if you want to replace special characters, like dots, you should employ full regular expression syntax, as shown in example below:

ctr_names <- c("Czech.Republic","New.Zealand","Great.Britain")
gsub("[.]", " ", ctr_names)

this will produce

[1] "Czech Republic" "New Zealand"    "Great Britain" 

You need to create fonts folder under assets folder in your project and put your TTF into it. Then in your Activity onCreate()

TextView myTextView=(TextView)findViewById(R.id.textBox);
Typeface typeFace=Typeface.createFromAsset(getAssets(),"fonts/mytruetypefont.ttf");
myTextView.setTypeface(typeFace);

Please note that not all TTF will work. While I was experimenting, it worked just for a subset (on Windows the ones whose name is written in small caps).

Use:

Response.Redirect(Request.RawUrl, true);

If you can change the order of the elements, floating will work.

section {_x000D_
  position: relative;_x000D_
  width: 50%;_x000D_
  border: 1px solid;_x000D_
}_x000D_
h1 {_x000D_
  display: inline;_x000D_
}_x000D_
div {_x000D_
  float: right;_x000D_
}

<section>_x000D_
  <div>_x000D_
    <button>button</button>_x000D_
  </div>_x000D_
_x000D_
  <h1>some long long long long header, a whole line, 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6</h1>_x000D_
</section>

?By placing the div before the h1 and floating it to the right, you get the desired effect.

Definitely it is a concern. Dockerfiles are commonly checked in to repositories and shared with other people. An alternative is to provide any credentials (usernames, passwords, tokens, anything sensitive) as environment variables at runtime. This is possible via the -e argument (for individual vars on the CLI) or --env-file argument (for multiple variables in a file) to docker run. Read this for using environmental with docker-compose.

Using --env-file is definitely a safer option since this protects against the secrets showing up in ps or in logs if one uses set -x.

However, env vars are not particularly secure either. They are visible via docker inspect, and hence they are available to any user that can run docker commands. (Of course, any user that has access to docker on the host also has root anyway.)

My preferred pattern is to use a wrapper script as the ENTRYPOINT or CMD. The wrapper script can first import secrets from an outside location in to the container at run time, then execute the application, providing the secrets. The exact mechanics of this vary based on your run time environment. In AWS, you can use a combination of IAM roles, the Key Management Service, and S3 to store encrypted secrets in an S3 bucket. Something like HashiCorp Vault or credstash is another option.

AFAIK there is no optimal pattern for using sensitive data as part of the build process. In fact, I have an SO question on this topic. You can use docker-squash to remove layers from an image. But there's no native functionality in Docker for this purpose.

You may find shykes comments on config in containers useful.

In your Case you can write the following jquery code:

$(document).ready(function(){

   $('.staff_on_site').click(function(){

     var rBtnVal = $(this).val();

     if(rBtnVal == "yes"){
         $("#no_of_staff").attr("readonly", false); 
     }
     else{ 
         $("#no_of_staff").attr("readonly", true); 
     }
   });
});

Here is the Fiddle: http://jsfiddle.net/P4QWx/3/

A slightly more efficient version of the bytes2String method is

private static final char[] hex = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};
private static String byteArray2Hex(byte[] bytes) {
    StringBuilder sb = new StringBuilder(bytes.length * 2);
    for (final byte b : bytes) {
        sb.append(hex[(b & 0xF0) >> 4]);
        sb.append(hex[b & 0x0F]);
    }
    return sb.toString();
}

Try with array_merge_recursive

$A = array('a' => 1, 'b' => 2, 'c' => 3);
$B = array('c' => 4, 'd'=> 5);
$c = array_merge_recursive($A,$B);

echo "<pre>";
print_r($c);
echo "</pre>";

will return

Array
(
    [a] => 1
    [b] => 2
    [c] => Array
        (
            [0] => 3
            [1] => 4
        )

    [d] => 5
)

If gives "permission denied" on adb shell -> su...

Some ROMs are running adbd daemon in secure mode (adbd has no root access and su command does not even show permission ask dialog on the device). In this case you will get "permission denied" when you try cmd -> adb shell -> su. The solution I've found is one app from the famous modder Chainfire called Adbd Insecure.

The JDK (JAVA_HOME) used to launch Eclipse is not necessarily the one used to compiled your project.

To see what JRE you can select for your project, check the preferences:

General ? Java Installed JRE

By default, if you have not added any JRE, the only one declared will be the one used to launched Eclipse (which can be defined in your eclipse.ini).

You can add any other JRE you want, including one compatible with your project.

After that, you will need to check in your project properties (or in the general preferences) what JRE is used, with what compliance level:

_{(source: standartux.fr)}

The different use case for setdefault() is when you don't want to overwrite the value of an already set key. defaultdict overwrites, while setdefault() does not. For nested dictionaries it is more often the case that you want to set a default only if the key is not set yet, because you don't want to remove the present sub dictionary. This is when you use setdefault().

Example with defaultdict:

>>> from collection import defaultdict()
>>> foo = defaultdict()
>>> foo['a'] = 4
>>> foo['a'] = 2
>>> print(foo)
defaultdict(None, {'a': 2})

setdefault doesn't overwrite:

>>> bar = dict()
>>> bar.setdefault('a', 4)
>>> bar.setdefault('a', 2)
>>> print(bar)
{'a': 4}

As said in Tatu Ulmanen's answer using the follow script will do the job

$('input:checkbox').removeAttr('checked');

But, as Blakomen's comment said, after version 1.6 it's better to use jQuery.prop() instead

Note that in jQuery v1.6 and higher, you should be using .prop('checked', false) instead for greater cross-browser compatibility

$('input:checkbox').prop('checked', false);

Be careful when using jQuery.each() it may cause performance issues. (also, avoid jQuery.find() in those case. Use each instead)

$('input[type=checkbox]').each(function() 
{ 
    $(this).prop('checked', false); 
});

http://php.net/manual/en/function.explode.php

$array = explode("\n", file_get_contents($filename));

This wont actually read it line by line, but it will get you an array which can be used line by line. There are a number of alternatives.

yes, it was introduced in 1993.

I believe it's:

git checkout master
git checkout -b good_quickfix2
git cherry-pick quickfix2^
git cherry-pick quickfix2

This is the official solution for setting the Java environment from www.java.com - here.

There are solutions for Windows 7, Windows Vista, Windows XP, Linux/Solaris and other shells.

Example

Windows 7

1. Select Computer from the Start menu
2. Choose System Properties from the context menu
3. Click Advanced system settings -> Advanced tab
4. Click on Environment Variables, under System Variables, find PATH, and click on it.
5. In the Edit windows, modify PATH by adding the location of the class to the value for PATH. If you do not have the item PATH, you may select to add a new variable and add PATH as the name and the location of the class as the value.
6. Reopen Command prompt window, and run your Java code.

The JAVA_HOME should point to the JDK home rather than the JRE home if you are going to be compiling stuff, likewise - I would try and install the JDK in a directory that doesn't include a space. Even if this is not your problem now, it can cause problems in the future!

Select 
    p.Name,
    p.SS,
    f.fear
From
    Persons p
left join
        Person_Fear pf
    inner join
        Fears f
    on
        pf.fearID = f.fearID
 on
    p.personID = pf.PersonID

Apache 2 mod_headers

You could also enable Apache 2 mod_headers. On Fedora it's already enabled by default. If you use Ubuntu/Debian, enable it like this:

# First enable headers module for Apache 2,
# and then restart the Apache2 service
a2enmod headers
apache2 -k graceful

On Ubuntu/Debian you can configure headers in the file /etc/apache2/conf-enabled/security.conf

#
# Setting this header will prevent MSIE from interpreting files as something
# else than declared by the content type in the HTTP headers.
# Requires mod_headers to be enabled.
#
#Header set X-Content-Type-Options: "nosniff"

#
# Setting this header will prevent other sites from embedding pages from this
# site as frames. This defends against clickjacking attacks.
# Requires mod_headers to be enabled.
#
Header always set X-Frame-Options: "sameorigin"
Header always set X-Content-Type-Options nosniff
Header always set X-XSS-Protection "1; mode=block"
Header always set X-Permitted-Cross-Domain-Policies "master-only"
Header always set Cache-Control "no-cache, no-store, must-revalidate"
Header always set Pragma "no-cache"
Header always set Expires "-1"
Header always set Content-Security-Policy: "default-src 'none';"
Header always set Content-Security-Policy: "script-src 'self' www.google-analytics.com adserver.example.com www.example.com;"
Header always set Content-Security-Policy: "style-src 'self' www.example.com;"

Note: This is the bottom part of the file. Only the last three entries are CSP settings.

The first parameter is the directive, the second is the sources to be white-listed. I've added Google analytics and an adserver, which you might have. Furthermore, I found that if you have aliases, e.g, www.example.com and example.com configured in Apache 2 you should add them to the white-list as well.

Inline code is considered harmful, and you should avoid it. Copy all the JavaScript code and CSS to separate files and add them to the white-list.

While you're at it you could take a look at the other header settings and install mod_security

Pass the decode pattern to ParseExact

Dim d as string = "201210120956"
Dim dt = DateTime.ParseExact(d, "yyyyMMddhhmm", Nothing)

ParseExact is available only from Net FrameWork 2.0.
If you are still on 1.1 you could use Parse, but you need to provide the IFormatProvider adequate to your string
