There is a point to only put commands and options in variables.

#! /bin/bash

if [ $# -ne 2 ]
then
    echo "Usage: `basename $0` DIRECTORY BACKUP_DIRECTORY"
    exit 1
fi

. standard_tools    

directory=$1
backup_directory=$2
current_date=$(date +%Y-%m-%dT%H-%M-%S)
backup_file="${backup_directory}/${current_date}.backup"

${tar_create} "${directory}" | ${openssl} | ${split_1024} "$backup_file"

You can relocate the commands to another file you source, so you can reuse the same commands and options across many scripts. This is very handy when you have a lot of scripts and you want to control how they all use tools. So standard_tools would contain:

export tar_create="tar cv"
export openssl="openssl des3 -salt"
export split_1024="split -b 1024m -"

A browser's default styles are defined in its user agent stylesheet, the sources of which you can find here. Unfortunately, the Cascading and Inheritance level 3 spec does not appear to propose a way to reset a style property to its browser default. However there are plans to reintroduce a keyword for this in Cascading and Inheritance level 4 — the working group simply hasn't settled on a name for this keyword yet (the link currently says revert, but it is not final). Information about browser support for revert can be found on caniuse.com.

While the level 3 spec does introduce an initial keyword, setting a property to its initial value resets it to its default value as defined by CSS, not as defined by the browser. The initial value of display is inline; this is specified here. The initial keyword refers to that value, not the browser default. The spec itself makes this note under the all property:

For example, if an author specifies all: initial on an element it will block all inheritance and reset all properties, as if no rules appeared in the author, user, or user-agent levels of the cascade.

This can be useful for the root element of a "widget" included in a page, which does not wish to inherit the styles of the outer page. Note, however, that any "default" style applied to that element (such as, e.g. display: block from the UA style sheet on block elements such as <div>) will also be blown away.

So I guess the only way right now using pure CSS is to look up the browser default value and set it manually to that:

div.foo { display: inline-block; }
div.foo.bar { display: block; }

(An alternative to the above would be div.foo:not(.bar) { display: inline-block; }, but that involves modifying the original selector rather than an override.)

I had to download the source files instead of just the compressed files that it says to use for quick start on the bootstrap website

Um, shouldn't the destructor be calling delete, rather than delete[]?

jQuery's data() method will give you access to data-* attributes, BUT, it clobbers the case of the attribute name. You can either use this:

$('#myButton').data("x10") // note the lower case

Or, you can use the attr() method, which preserves your case:

$('#myButton').attr("data-X10")

Try both methods here: http://jsfiddle.net/q5rbL/

Be aware that these approaches are not completely equivalent. If you will change the data-* attribute of an element, you should use attr(). data() will read the value once initially, then continue to return a cached copy, whereas attr() will re-read the attribute each time.

Note that jQuery will also convert hyphens in the attribute name to camel case (source -- i.e. data-some-data == $(ele).data('someData')). Both of these conversions are in conformance with the HTML specification, which dictates that custom data attributes should contain no uppercase letters, and that hyphens will be camel-cased in the dataset property (source). jQuery's data method is merely mimicking/conforming to this standard behavior.

We will set the directory to be very secure, denying access for all file types. Below is the code you want to insert into the .htaccess file.

Order Allow,Deny 
Deny from all 

Since we have now set the security, we now want to allow access to our desired file types. To do that, add the code below to the .htaccess file under the security code you just inserted.

<FilesMatch "\.(jpg|gif|png|php)$">
Order Deny,Allow
   Allow from all
</FilesMatch>

your final .htaccess file will look like

Order Allow,Deny 
Deny from all 

<FilesMatch "\.(jpg|gif|png|php)$">
Order Deny,Allow
   Allow from all
</FilesMatch>

Summarising @Rasmi Ranjan Nayak and @nogard answers and adding another option:

On the console

You should use the flag --gtest_filter, like

--gtest_filter=Test_Cases1*

(You can also do this in Properties|Configuration Properties|Debugging|Command Arguments)

On the environment

You should set the variable GTEST_FILTER like

export GTEST_FILTER = "Test_Cases1*"

On the code

You should set a flag filter, like

::testing::GTEST_FLAG(filter) = "Test_Cases1*";

such that your main function becomes something like

int main(int argc, char **argv) {
    ::testing::InitGoogleTest(&argc, argv);
    ::testing::GTEST_FLAG(filter) = "Test_Cases1*";
    return RUN_ALL_TESTS();
}

See section Running a Subset of the Tests for more info on the syntax of the string you can use.

Their are two methods you can use to pass an integer. One is as shown below.

A.class

Intent myIntent = new Intent(A.this, B.class);
myIntent.putExtra("intVariableName", intValue);
startActivity(myIntent);

B.class

Intent intent = getIntent();
int intValue = intent.getIntExtra("intVariableName", 0);

The other method converts the integer to a string and uses the following code.

A.class

Intent intent = new Intent(A.this, B.class);
Bundle extras = new Bundle();
extras.putString("StringVariableName", intValue + "");
intent.putExtras(extras);
startActivity(intent);

The code above will pass your integer value as a string to class B. On class B, get the string value and convert again as an integer as shown below.

B.class

   Bundle extras = getIntent().getExtras();
   String stringVariableName = extras.getString("StringVariableName");
   int intVariableName = Integer.parseInt(stringVariableName);

Solution:

var answerInt = [];
var answerString = "1,2,3,4";
answerString.split(',').forEach(function (item) {
   answerInt.push(parseInt(item))
});

Similar to John Wilkey's answer I would run python2 by finding which python, something like using /usr/bin/python and then creating an alias in .bash_profile:

alias python2="/usr/bin/python"

I can now run python3 by calling python and python2 by calling python2.

There are at least two solutions:

1. You need Visual Studio 2010 installed, then from Visual Studio 2010, View -> Solution Explorer -> Right Click on your project -> Choose Properties from the context menu, you'll get the windows "your project name" Property Pages -> Configuration Properties -> General -> Platform toolset, choose "Visual Studio 2010 (v100)".
2. You need the Visual Studio 2012 Update 1 described in Windows XP Targeting with C++ in Visual Studio 2012

How about this? =D

VAL_TO_CHECK="1.00001"
if [ $(awk '{printf($1 >= $2) ? 1 : 0}' <<<" $VAL_TO_CHECK 1 ") -eq 1 ] ; then
    echo "$VAL_TO_CHECK >= 1"
else
    echo "$VAL_TO_CHECK < 1"
fi

The problem here is that you are including commands.c in commands.h before the function prototype. Therefore, the C pre-processor inserts the content of commands.c into commands.h before the function prototype. commands.c contains the function definition. As a result, the function definition ends up before than the function declaration causing the error.

The content of commands.h after the pre-processor phase looks like this:

#ifndef COMMANDS_H_
#define COMMANDS_H_

// function definition
void f123(){

}

// function declaration
void f123();

#endif /* COMMANDS_H_ */

This is an error because you can't declare a function after its definition in C. If you swapped #include "commands.c" and the function declaration the error shouldn't happen because, now, the function prototype comes before the function declaration.

However, including a .c file is a bad practice and should be avoided. A better solution for this problem would be to include commands.h in commands.c and link the compiled version of command to the main file. For example:

commands.h

#ifndef COMMANDS_H_
#define COMMANDS_H_

void f123(); // function declaration

#endif

commands.c

#include "commands.h"

void f123(){} // function definition

Just do

git pull origin [branch]

and then you should be able to push.

If you have commits on your own and didn't push it the branch yet, try

git pull --rebase origin [branch]

and then you should be able to push.

Can also be done this way..

regex=re.compile('^hello')

## THIS WAY YOU CAN CHECK FOR MULTIPLE STRINGS

You may use an html parser (many useful links here: java html parser).

The process is called 'grabbing website content'. Search 'grab website content java' for further invertigation.

For completeness and correct resource management:

        ICursor cursor = null;
        try
        {

            cursor = db.RawQuery("SELECT * FROM " + RECORDS_TABLE + " WHERE " + RECORD_ID + "=?", new String[] { id + "" });

            if (cursor.Count > 0)
            {
                cursor.MoveToFirst();
            }
            return GetRecordFromCursor(cursor); // Copy cursor props to custom obj
        }
        finally // IMPORTANT !!! Ensure cursor is not left hanging around ...
        {
            if(cursor != null)
                cursor.Close();
        }

When using Java8 it would be more easier and a single liner only.

It seems that there is a direct way:

If you really just want to rename branches remotely (without renaming any local branches at the same time) you can do this with a single command like

git push <remote> <remote>/<old_name>:refs/heads/<new_name> :<old_name>

The only workable solution is to restore the .bak file. The contents and the structure of those files are not documented and therefore, there's really no way (other than an awful hack) to get this to work - definitely not worth your time and the effort!

The only tool I'm aware of that can make sense of .bak files without restoring them is Red-Gate SQL Compare Professional (and the accompanying SQL Data Compare) which allow you to compare your database structure against the contents of a .bak file. Red-Gate tools are absolutely marvelous - highly recommended and well worth every penny they cost!

And I just checked their web site - it does seem that you can indeed restore a single table from out of a .bak file with SQL Compare Pro ! :-)

Use the following to evaluate an expression (constant 0 evaluates to false).

#if 0

#endif

This might help. It contains many examples which will be useful in understanding.

You can do this concisely using the toolbelt vg. It's a light layer on top of numpy and it supports single values and stacked vectors.

import numpy as np
import vg

x = np.array([1, 2, 3, 4, 5])
mag1 = np.linalg.norm(x)
mag2 = vg.magnitude(x)
print mag1 == mag2
# True

I created the library at my last startup, where it was motivated by uses like this: simple ideas which are far too verbose in NumPy.

The key issue is that a glyph in a string takes 32 bits (16 bits for a character code) but a byte only has 8 bits to spare. A one-to-one mapping doesn't exist unless you restrict yourself to strings that only contain ASCII characters. System.Text.Encoding has lots of ways to map a string to byte[], you need to pick one that avoids loss of information and that is easy to use by your client when she needs to map the byte[] back to a string.

Utf8 is a popular encoding, it is compact and not lossy.

This answer is based on the title and not the specific case in the original post.

I had an insert procedure that kept throwing this annoying error, and even though the error says, "procedure....has too many arguments specified," the fact is that the procedure did NOT have enough arguments.

The table had an incremental id column, and since it is incremental, I did not bother to add it as a variable/argument to the proc, but it turned out that it is needed, so I added it as @Id and viola like they say...it works.

Use mvn --help and you can see the options list.

There is an option like -nsu,--no-snapshot-updates Suppress SNAPSHOT updates

So use command mvn install -nsu can force compile with local repository.

adding org.apache.derby dependency solved my issue.

<dependency>
            <groupId>org.apache.derby</groupId>

You could name the anonymous delegate :-)

And you can write the second as:

someList.ForEach(s => s.ToUpper())

Which I prefer, and saves a lot of typing.

As Joachim says, parallelism is easier to apply to the second form.

This answer didn't work for me, but I found the answer myself. No one, however, has posted my question. I'm too lazy to ask it and then answer it, so will just put it here.

This is for the following query:

data = Leaderboard.objects.filter(id=custom_user.id).values(
    'value1',
    'value2',
    'value3')

In template:

{% for dictionary in data %}
  {% for key, value in dictionary.items %}
    <p>{{ key }} : {{ value }}</p>
  {% endfor %}
{% endfor %}

You can either pass the parameter in the task constructor or when you call execute:

AsyncTask<Object, Void, MyTaskResult>

The first parameter (Object) is passed in doInBackground. The third parameter (MyTaskResult) is returned by doInBackground. You can change them to the types you want. The three dots mean that zero or more objects (or an array of them) may be passed as the argument(s).

public class MyActivity extends AppCompatActivity {

    TextView textView1;
    TextView textView2;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);    
        textView1 = (TextView) findViewById(R.id.textView1);
        textView2 = (TextView) findViewById(R.id.textView2);

        String input1 = "test";
        boolean input2 = true;
        int input3 = 100;
        long input4 = 100000000;

        new MyTask(input3, input4).execute(input1, input2);
    }

    private class MyTaskResult {
        String text1;
        String text2;
    }

    private class MyTask extends AsyncTask<Object, Void, MyTaskResult> {
        private String val1;
        private boolean val2;
        private int val3;
        private long val4;


        public MyTask(int in3, long in4) {
            this.val3 = in3;
            this.val4 = in4;

            // Do something ...
        }

        protected void onPreExecute() {
            // Do something ...
        }

        @Override
        protected MyTaskResult doInBackground(Object... params) {
            MyTaskResult res = new MyTaskResult();
            val1 = (String) params[0];
            val2 = (boolean) params[1];

            //Do some lengthy operation    
            res.text1 = RunProc1(val1);
            res.text2 = RunProc2(val2);

            return res;
        }

        @Override
        protected void onPostExecute(MyTaskResult res) {
            textView1.setText(res.text1);
            textView2.setText(res.text2);

        }
    }

}

I had the same problem and I prefer not to replace the entire ArrayAdapter with a new instance continuously. Thus I have the AdapterHelper do the heavy lifting somewhere else.

Add this where you would normally (try to) call notify

new AdapterHelper().update((ArrayAdapter)adapter, new ArrayList<Object>(yourArrayList));
adapter.notifyDataSetChanged();

AdapterHelper class

public class AdapterHelper {
    @SuppressWarnings({ "rawtypes", "unchecked" })
    public void update(ArrayAdapter arrayAdapter, ArrayList<Object> listOfObject){
        arrayAdapter.clear();
        for (Object object : listOfObject){
            arrayAdapter.add(object);
        }
    }
}

You can find a list of formatting escapes on this page.

%d is a signed integer, while %u is an unsigned integer. Pointers (when treated as numbers) are usually non-negative.

If you actually want to display a pointer, use the %p format specifier.

Lets say you have Class A as superclass and Class B subclass of A.

public class A {

    public void printFromA(){
        System.out.println("Inside A");
    }
}
public class B extends A {

    public void printFromB(){
        System.out.println("Inside B");
    }

}

public class MainClass {

    public static void main(String []args){

        A a = new B();
        a.printFromA(); //this can be called without typecasting

        ((B)a).printFromB(); //the method printFromB needs to be typecast 
    }
}

Update 2017: I would use an async function if the environment supports it:

async function readFiles(files) {
  for(const file of files) {
    await readFile(file);
  }
};

If you'd like, you can defer reading the files until you need them using an async generator (if your environment supports it):

async function* readFiles(files) {
  for(const file of files) {
    yield await readFile(file);
  }
};

Update: In second thought - I might use a for loop instead:

var readFiles = function(files) {
  var p = Promise.resolve(); // Q() in q

  files.forEach(file =>
      p = p.then(() => readFile(file)); 
  );
  return p;
};

Or more compactly, with reduce:

var readFiles = function(files) {
  return files.reduce((p, file) => {
     return p.then(() => readFile(file));
  }, Promise.resolve()); // initial
};

In other promise libraries (like when and Bluebird) you have utility methods for this.

For example, Bluebird would be:

var Promise = require("bluebird");
var fs = Promise.promisifyAll(require("fs"));

var readAll = Promise.resolve(files).map(fs.readFileAsync,{concurrency: 1 });
// if the order matters, you can use Promise.each instead and omit concurrency param

readAll.then(function(allFileContents){
    // do stuff to read files.
});

Although there is really no reason not to use async await today.

It's a named export vs a default export. export const is a named export that exports a const declaration or declarations.

To emphasize: what matters here is the export keyword as const is used to declare a const declaration or declarations. export may also be applied to other declarations such as class or function declarations.

Default Export (export default)

You can have one default export per file. When you import you have to specify a name and import like so:

import MyDefaultExport from "./MyFileWithADefaultExport";

You can give this any name you like.

Named Export (export)

With named exports, you can have multiple named exports per file. Then import the specific exports you want surrounded in braces:

// ex. importing multiple exports:
import { MyClass, MyOtherClass } from "./MyClass";
// ex. giving a named import a different name by using "as":
import { MyClass2 as MyClass2Alias } from "./MyClass2";

// use MyClass, MyOtherClass, and MyClass2Alias here

Or it's possible to use a default along with named imports in the same statement:

import MyDefaultExport, { MyClass, MyOtherClass} from "./MyClass";

Namespace Import

It's also possible to import everything from the file on an object:

import * as MyClasses from "./MyClass";
// use MyClasses.MyClass, MyClasses.MyOtherClass and MyClasses.default here

Notes

• The syntax favours default exports as slightly more concise because their use case is more common (See the discussion here).

• A default export is actually a named export with the name default so you are able to import it with a named import:

  import { default as MyDefaultExport } from "./MyFileWithADefaultExport";
  

Within your component, you can define an array of number (ES6) as described below:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill(0).map((x,i)=>i);
  }
}

See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.

You can then iterate over this array with ngFor:

@View({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Or shortly:

@View({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Hope it helps you, Thierry

Edit: Fixed the fill statement and template syntax.

Assert by exception message:

    try {
        MyAgent.getNameByNode("d");
    } catch (Exception e) {
        Assert.assertEquals("Failed to fetch data.", e.getMessage());
    }

It is not necessary to have two routes.

Simply add (/*)? at the end of your path string.

For example, app.get('/hello/world(/*)?' /* ... */)

Here is a fully working example, feel free to copy and paste this into a .js file to run with node, and play with it in a browser (or curl):

const app = require('express')()

// will be able to match all of the following
const test1 = 'http://localhost:3000/hello/world'
const test2 = 'http://localhost:3000/hello/world/'
const test3 = 'http://localhost:3000/hello/world/with/more/stuff'

// but fail at this one
const failTest = 'http://localhost:3000/foo/world'

app.get('/hello/world(/*)?', (req, res) => res.send(`
    This will match at example endpoints: <br><br>
    <pre><a href="${test1}">${test1}</a></pre>
    <pre><a href="${test2}">${test2}</a></pre>
    <pre><a href="${test3}">${test3}</a></pre>

    <br><br> Will NOT match at: <pre><a href="${failTest}">${failTest}</a></pre>
`))

app.listen(3000, () => console.log('Check this out in a browser at http://localhost:3000/hello/world!'))

Boom, Google Chrome and anyone else try defeat this then.

I was able to get this implemented today 7th September 2017, but using a FormCollection of random strings that generated in my MVC View.

I would first get a new random key in my index controller of my login page , encrypt and create a new totally unique random string (i actually used a 256 bit cypher to perform this, and a unique cypher and authentication key), i then append plain text 'Username' and 'Password' on the end of each string to later help me identify from the repsonding view controller the username and password. You could also change that plain string to anything as long as you know the pattern and it's unique.

In my view, I then used these variables appropriately and then in the responding controller - searched through a FormCollection and found my matching variables - and then used the Key-Value of that item as the corresponding Username and Password to process appropriately.

The other issue i had which i think is sneaky of Chrome, is that any

Any thoughts ?

<style>
    @@font-face {
      font-family: 'password';
      font-style: normal;
      font-weight: 400;

    }
</style>

<input type="text" name="@Model.UsernameRandomNameString" />
<input style="font-family: 'password'" type="text" name="@Model.PasswordRandomNameString" />

            {
                UsernameRandomNameString = Cryptography.SimpleEncrypt("Username", UniqueGeneratorKey, UniqueGeneratorKey) + "Username",
                PasswordRandomNameString = Cryptography.SimpleEncrypt("Password", UniqueGeneratorKey, UniqueGeneratorKey) + "Password",
            };

I think it a hell of a workaround, but hey it works, and i think it could also be future proof unless google determines the URL of the page has key words in it, then appropriately just adds its stupid extensions on top on any input field - but that's a little drastic.

Just thought i'd share this with anyone who needs more clarity on how to achieve this:

Once upon a time I was looking for something similar - a lightweight yet fully functional HTTP server that I could easily embed and customize. I found two types of potential solutions:

• Full servers that are not all that lightweight or simple (for an extreme definition of lightweight.)
• Truly lightweight servers that aren't quite HTTP servers, but glorified ServerSocket examples that are not even remotely RFC-compliant and don't support commonly needed basic functionality.

So... I set out to write JLHTTP - The Java Lightweight HTTP Server.

You can embed it in any project as a single (if rather long) source file, or as a ~50K jar (~35K stripped) with no dependencies. It strives to be RFC-compliant and includes extensive documentation and many useful features while keeping bloat to a minimum.

Features include: virtual hosts, file serving from disk, mime type mappings via standard mime.types file, directory index generation, welcome files, support for all HTTP methods, conditional ETags and If-* header support, chunked transfer encoding, gzip/deflate compression, basic HTTPS (as provided by the JVM), partial content (download continuation), multipart/form-data handling for file uploads, multiple context handlers via API or annotations, parameter parsing (query string or x-www-form-urlencoded body), etc.

I hope others find it useful :-)

Just as Brian said, you can use remote debugging:

mvn exec:exec -Dexec.executable="java" -Dexec.args="-classpath %classpath -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044 com.mycompany.app.App"

Then in your eclipse, you can use remote debugging and attach the debugger to localhost:1044.

This works for me

$('.someclass').click(function() {
    $varName = $(this).data('fulltext');
    console.log($varName);
});

Just as Daniel said "Git and TFVC are the two source control options in TFS". Fortunately both are supported for now in VS Code.

You need to install the Azure Repos Extension for Visual Studio Code. The process of installing is pretty straight forward.

1. Search for Azure Repos in VS Code and select to install the one by Microsoft
2. Open File -> Preferences -> Settings

3. Add the following lines to your user settings

   If you have VS 2015 installed on your machine, your path to Team Foundation tool (tf.exe) may look like this:

   {
       "tfvc.location": "C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\Common7\\IDE\\tf.exe",
       "tfvc.restrictWorkspace": true
   }

   Or for VS 2017:

   {
       "tfvc.location": "C:\\Program Files (x86)\\Microsoft Visual Studio\\2017\\Enterprise\\Common7\\IDE\\CommonExtensions\\Microsoft\\TeamFoundation\\Team Explorer\\tf.exe",
       "tfvc.restrictWorkspace": true
   }

4. Open a local folder (repository), From View -> Command Pallette ..., type team signin

5. Provide user name --> Enter --> Provide password to connect to TFS.

Please refer to below links for more details:

• Using Visual Studio Code & Team Foundation Version Control (TFVC)
• Team Foundation Version Control (TFVC) Support
• Using Version Control in VS Code

Note that Server Workspaces are not supported:

"TFVC support is limited to Local workspaces":

I have met the same problem. My project is running on the local server. I checked my php code.

$db = mysqli_connect('localhost', 'root', 'root', 'smart');

I use localhost to connect to my local database. That maybe the cause of the problem which you're describing. You can modify your HOSTS file. Add the line

127.0.0.1 localhost.

There are a few different ways to do this but following is a quick sample of one way.

<img src="yourimage.jpg" style="float:right" /><div style="clear:both">Your text here.</div>

I used inline styles for this sample but you can easily place these in a stylesheet and reference the class or id.

2 ways:-

1st one Custom Query

@Modifying
@Query("delete from User where firstName = :firstName")
void deleteUsersByFirstName(@Param("firstName") String firstName);

2nd one JPA Query by method

List<User> deleteByLastname(String lastname);

When you go with query by method (2nd way) it will first do a get call

select * from user where last_name = :firstName

Then it will load it in a List Then it will call delete id one by one

delete from user where id = 18
delete from user where id = 19

First fetch list of object, then for loop to delete id one by one

But, the 1st option (custom query),

It's just a single query It will delete wherever the value exists.

Go through this link too https://www.baeldung.com/spring-data-jpa-deleteby

Something like this might work:

$("body").attr("class", "about");

It uses jQuery's attr() to add the class 'about' to the body.

I want to propose another way, how to solve limitation with IN operator.

For example we have following query

select *
from Users U
WHERE U.ID in (@ids)

We want to pass several IDs to filter users. Unfortunately it is not possible to do with C# in easy way. But I have fount workaround for this by using "string_split" function. We need to rewrite a bit our query to following.

declare @ids nvarchar(max) = '1,2,3'

SELECT *
FROM Users as U
CROSS APPLY string_split(@ids, ',') as UIDS
WHERE U.ID = UIDS.value

Now we can easily pass one parameter enumeration of values separated by comma.

If you are using Carbon (and you should, it's awesome!) with Laravel, you can simply do the following:

->where('created_at', '>=', Carbon::today())

Besides now() and today(), you can also use yesterday() and tomorrow() and then use the following:

• startOfDay()/endOfDay()
• startOfWeek()/endOfWeek()
• startOfMonth()/endOfMonth()
• startOfYear()/endOfYear()
• startOfDecade()/endOfDecade()
• startOfCentury()/endOfCentury()

There is no inherent reason that a simple batch file would run in XP but not Windows 10. It is possible you are referencing a command or a 3rd party utility that no longer exists. To know more about what is actually happening, you will need to do one of the following:

• Add a pause to the batch file so that you can see what is happening before it exits.
  1. Right click on one of the .bat files and select "edit". This will open the file in notepad.
  2. Go to the very end of the file and add a new line by pressing "enter".
  3. type pause.
  4. Save the file.
  5. Run the file again using the same method you did before.

- OR -

• Run the batch file from a static command prompt so the window does not close.
  1. In the folder where the .bat files are located, hold down the "shift" key and right click in the white space.
  2. Select "Open Command Window Here".
  3. You will now see a new command prompt. Type in the name of the batch file and press enter.

Once you have done this, I recommend creating a new question with the output you see after using one of the methods above.

This happened for me when I was trying to plot an imagePath, instead of the image itself. The fix was to load the image, and plotting it.

Python 3.4+

Use html.unescape():

import html
print(html.unescape('£682m'))

FYI html.parser.HTMLParser.unescape is deprecated, and was supposed to be removed in 3.5, although it was left in by mistake. It will be removed from the language soon.

Python 2.6-3.3

You can use HTMLParser.unescape() from the standard library:

• For Python 2.6-2.7 it's in HTMLParser
• For Python 3 it's in html.parser

>>> try:
...     # Python 2.6-2.7 
...     from HTMLParser import HTMLParser
... except ImportError:
...     # Python 3
...     from html.parser import HTMLParser
... 
>>> h = HTMLParser()
>>> print(h.unescape('£682m'))
£682m

You can also use the six compatibility library to simplify the import:

>>> from six.moves.html_parser import HTMLParser
>>> h = HTMLParser()
>>> print(h.unescape('£682m'))
£682m

There is relevant info on a configuration of CSRF with respect to API controllers on api.rubyonrails.org:

?

It's important to remember that XML or JSON requests are also affected and if you're building an API you should change forgery protection method in ApplicationController (by default: :exception):

class ApplicationController < ActionController::Base
  protect_from_forgery unless: -> { request.format.json? }
end

We may want to disable CSRF protection for APIs since they are typically designed to be state-less. That is, the request API client will handle the session for you instead of Rails.

?

You are calling nextInt statically by using Random.nextInt.

Instead, create a variable, Random r = new Random(); and then call r.nextInt(10).

It would be definitely worth while to check out:

• What is the reason behind "non staticmethod cannot be referenced from a static context"?

Update:

You really should replace this line,

Random Random = new Random(); 

with something like this,

Random r = new Random();

If you use variable names as class names you'll run into a boat load of problems. Also as a Java convention, use lowercase names for variables. That might help avoid some confusion.

I have fixed same issue on Amazon Linux AMI 2016.09 (Centos 7) by taking following steps.

Open your www.conf files (Example : sudo nano /etc/php-fpm.d/www.conf) Lastly, find the lines that set the listen.owner and listen.group and change their values from "nobody" to "nginx":

listen.owner = nginx
listen.group = nginx
listen.mode = 0666

Lastly, find the lines that set the user and group and change their values from "apache" to "nginx":

user = nginx
group = nginx

Restart php-fpm (sudo service php-fpm restart)

You can simply use the imutils package to do the rotation. it has two methods

1. rotate: Rotate the image at specified angle. however the drawback is image might get cropped if it is not a square image.
2. Rotate_bound: it overcomes the problem happened with rotate. It adjusts the size of the image accordingly while rotating the image.

more info you can get on this blog: https://www.pyimagesearch.com/2017/01/02/rotate-images-correctly-with-opencv-and-python/

PYTHONPATH is an environment variable those content is added to the sys.path where Python looks for modules. You can set it to whatever you like.

However, do not mess with PYTHONPATH. More often than not, you are doing it wrong and it will only bring you trouble in the long run. For example, virtual environments could do strange things…

I would suggest you learned how to package a Python module properly, maybe using this easy setup. If you are especially lazy, you could use cookiecutter to do all the hard work for you.

A simple solution:

   <a href="#" onmouseover="this.style.color='orange';" onmouseout="this.style.color='';">My Link</a>

Or

<script>
 /** Change the style **/
 function overStyle(object){
    object.style.color = 'orange';
    // Change some other properties ...
 }

 /** Restores the style **/
 function outStyle(object){
    object.style.color = 'orange';
    // Restore the rest ...
 }
</script>

<a href="#" onmouseover="overStyle(this)" onmouseout="outStyle(this)">My Link</a>

To see the full code(query) written in stored procedure/ functions, Use below Command:

sp_helptext procedure/function_name

for function name and procedure name don't add prefix 'dbo.' or 'sys.'.

don't add brackets at the end of procedure or function name and also don't pass the parameters.

use sp_helptext keyword and then just pass the procedure/ function name.

use below command to see full code written for Procedure:

sp_helptext ProcedureName

use below command to see full code written for function:

sp_helptext FunctionName

As an alternative, you could add it as a script parameter for input as part of script execution

 param(
      [Parameter(Mandatory = $True,valueFromPipeline=$true)][String] $value1,
      [Parameter(Mandatory = $True,valueFromPipeline=$true)][String] $value2
      )

Another way to list only the files is to use:
git diff-tree --no-commit-id --name-only -r HEAD^..HEAD
Or you can use any two commit IDs

You have to use the String method .toLowerCase() or .toUpperCase() on both the input and the string you are trying to match it with.

Example:

public static void findPatient() {
    System.out.print("Enter part of the patient name: ");
    String name = sc.nextLine();

    System.out.print(myPatientList.showPatients(name));
}

//the other class
ArrayList<String> patientList;

public void showPatients(String name) {
    boolean match = false;

    for(String matchingname : patientList) {
        if (matchingname.toLowerCase().contains(name.toLowerCase())) {
            match = true;
        }
    }
}

Yes,

You are trying to access an element of the list that does not exist.

MyList = ["item1", "item2"]
print MyList[0] # Will work
print MyList[1] # Will Work
print MyList[2] # Will crash.

Have you got an off-by-one error?

The threading.Timer object (documentation) can count the ten seconds, then get it to set an Event flag indicating that the loop should exit.

The documentation indicates that the timing might not be exact - you'd have to test whether it's accurate enough for your game.

• Kotlin Version

To retain current font in addition to text style:

textView.apply {
    setTypeface(typeface, Typeface.NORMAL)
    // or
    setTypeface(typeface, Typeface.BOLD)
    // or
    setTypeface(typeface, Typeface.ITALIC)
    // or
    setTypeface(typeface, Typeface.BOLD_ITALIC)
}

Select Top 1 can easily resolve it without the need of any sequence/order.

Create Function Test_Range()

Begin

Declare @ID Varchar(10) = ''
Declare @Rows Int, @Row Int = 0
Declare @Num Int, @RangeTo Int

Declare @RangeTable Table (ID Varchar(10), RangeFrom Int, RangeTo Int)
Insert Into @RangeTable Values ('A', 1, 10)
Insert Into @RangeTable Values ('B', 25,30)

Set @Rows = (Select Count(*) From @RangeTable)

While @Row <= @Rows
Begin
    Set @Row = @Row + 1
    Select Top 1 @ID = ID, @Num = RangeFrom, @RangeTo = RangeTo  From @RangeTable
    Where ID > @ID
    While @Num <= @RangeTo
    Begin
        Insert Into @Result Values (@Num)
        Set @Num = @Num + 1
    End
End
Return
End

Make it dataType instead of datatype.

And add below code in php as your ajax request is expecting json and will not accept anything, but json.

header('Content-Type: application/json');

Correct Content type for JSON and JSONP

The response visible in firebug is text data. Check Content-Type of the response header to verify, if the response is json. It should be application/json for dataType:'json' and text/html for dataType:'html'.

Is it as optional functionality.

If you won't provide it when user will try to purchase non-consumable product AppStore will restore old transaction. But your app will think that this is new transaction.

If you will provide restore mechanism then your purchase manager will see restored transaction.

If app should distinguish this options then you should provide functionality for restoring previously purchased products.

This should do the trick:

$($.parseJSON(data.msg)).map(function () {
    return $('<option>').val(this.value).text(this.label);
}).appendTo('#combobox');

Here's the distinction between ajax and getJSON (from the jQuery documentation):

[getJSON] is a shorthand Ajax function, which is equivalent to:

$.ajax({
  url: url,
  dataType: 'json',
  data: data,
  success: callback
});

EDIT: To be clear, part of the problem was that the server's response was returning a json object that looked like this:

{
    "msg": '[{"value":"1","label":"xyz"}, {"value":"2","label":"abc"}]'
}

...So that msg property needed to be parsed manually using $.parseJSON().

This may be what your after:

SELECT Count(Owner_ID), Name
FROM (
    SELECT M.Owner_ID, O.Name, T.Type
    FROM Transport As T, Owner As O, Motorbike As M
    WHERE T.Type = 'Motorbike'
    AND O.Owner_ID = M.Owner_ID
    AND T.Type_ID = M.Motorbike_ID

    UNION ALL

    SELECT C.Owner_ID, O.Name, T.Type
    FROM Transport As T, Owner As O, Car As C
    WHERE T.Type = 'Car'
    AND O.Owner_ID = C.Owner_ID
    AND T.Type_ID = C.Car_ID
)
GROUP BY Owner_ID

I had this problem too and stoping services using port 80 didn't helped. I resolved it by following this procedure (found on a french board):

1. Launch RegEdit
2. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP
3. Change the value of "start" to 4 (disabled)
4. Reboot your computer

Not sure how this affect other services, but it solved permanently the issue and so far I didn't see any issue.

There is no good solution to your problem, so here is an okey solution ;-)

It keeps your efficiency when assertions are disabled and when assertions are enabled it will raise an assertion error when the hash value is wrong.

I suspect that the D programming language could compute the hash value during compile time, thus removing the need to explicitly write down the hash value.

template <std::size_t h>
struct prehash
{
    const your_string_type str;

    static const std::size_t hash_value = h;

    pre_hash(const your_string_type& s) : str(s)
    {
        assert(_myhash(s) == hash_value);
    }
};

/* ... */

std::size_t h = _myhash(mystring);

static prehash<66452> first_label = "label1";

switch (h) {
case first_label.hash_value:
    // ...
    ;
}

By the way, consider removing the initial underscore from the declaration of _ myhash() (sorry but stackoverflow forces me to insert a space between _ and myhash). A C++ implementation is free to implement macros with names starting with underscore and an uppercase letter (Item 36 of "Exceptional C++ Style" by Herb Sutter), so if you get into the habit of giving things names that start underscore, then a beautiful day could come when you give a symbol a name that starts with underscore and an uppercase letter, where the implementation has defined a macro with the same name.

You may use the Range.Find method:

http://msdn.microsoft.com/en-us/library/office/ff839746.aspx

This will get you the first cell which contains the search string. By repeating this with setting the "After" argument to the next cell you will get all other occurrences until you are back at the first occurrence.

This will likely be much faster.

Just add profile to session configuration before client call. boto3.session.Session(profile_name='YOUR_PROFILE_NAME').client('cloudwatch')

Simply just do something like this:

li { 
  cursor: pointer;
}

I apply it on your code to see how it works:

li {_x000D_
  cursor: pointer;_x000D_
}

<ul>_x000D_
  <li>foo</li>_x000D_
  <li>goo</li>_x000D_
</ul>

Note: Also DO not forget you can have any hand cursor with customised cursor, you can create fav hand icon like this one for example:

div {_x000D_
  display: block;_x000D_
  width: 400px;_x000D_
  height: 400px;_x000D_
  background: red;_x000D_
  cursor: url(http://findicons.com/files/icons/1840/free_style/128/hand.png) 4 12, auto;_x000D_
}

<div>_x000D_
</div>

I'm going to approach this as if you have a Users model:

Users.cs

public class Users
{
    [Key]
    public int UserId { get; set; }

    [Required]
    public string UserName { get; set; }

    public int RoleId { get; set; }

    [ForeignKey("RoleId")]
    public virtual DbUserRoles DbUserRoles { get; set; }
}

and a DbUserRoles model that represented a table by that name in the database:

DbUserRoles.cs

public partial class DbUserRoles
{
    [Key]
    public int UserRoleId { get; set; }

    [Required]
    [StringLength(30)]
    public string UserRole { get; set; }
}

Once you had that cleaned up, you should just be able to create and fill a collection of UserRoles, like this, in your Controller:

var userRoleList = GetUserRolesList();
ViewData["userRoles"] = userRolesList;

and have these supporting functions:

private static SelectListItem[] _UserRolesList;

/// <summary>
/// Returns a static category list that is cached
/// </summary>
/// <returns></returns>
public SelectListItem[] GetUserRolesList()
{
    if (_UserRolesList == null)
    {
        var userRoles = repository.GetAllUserRoles().Select(a => new SelectListItem()
         {
             Text = a.UserRole,
             Value = a.UserRoleId.ToString()
         }).ToList();
         userRoles.Insert(0, new SelectListItem() { Value = "0", Text = "-- Please select your user role --" });

        _UserRolesList = userRoles.ToArray();
    }

    // Have to create new instances via projection
    // to avoid ModelBinding updates to affect this
    // globally
    return _UserRolesList
        .Select(d => new SelectListItem()
    {
         Value = d.Value,
         Text = d.Text
    })
     .ToArray();
}

Repository.cs

My Repository function GetAllUserRoles() for the function, above:

public class Repository
{
    Model1 db = new Model1(); // Entity Framework context

    // User Roles
    public IList<DbUserRoles> GetAllUserRoles()
    {
        return db.DbUserRoles.OrderBy(e => e.UserRoleId).ToList();
    }
}

AddNewUser.cshtml

Then do this in your View:

<table>
    <tr>
        <td>
            @Html.EditorFor(model => model.UserName,
                  htmlAttributes: new { @class = "form-control" }
                  )
        </td>
        <td>
            @Html.DropDownListFor(model => model.RoleId,
                  new SelectList( (IEnumerable<SelectListItem>)ViewData["userRoles"], "Value", "Text", model.RoleId),
                  htmlAttributes: new { @class = "form-control" }
                  )
         </td>
     </tr>
 </table>

Using iTextSharp.dll

protected void Page_Load(object sender, EventArgs e)
{
    String[] files = @"C:\ENROLLDOCS\A1.pdf,C:\ENROLLDOCS\A2.pdf".Split(',');
    MergeFiles(@"C:\ENROLLDOCS\New1.pdf", files);
}
public void MergeFiles(string destinationFile, string[] sourceFiles)
{
    if (System.IO.File.Exists(destinationFile))
        System.IO.File.Delete(destinationFile);

    string[] sSrcFile;
    sSrcFile = new string[2];

    string[] arr = new string[2];
    for (int i = 0; i <= sourceFiles.Length - 1; i++)
    {
        if (sourceFiles[i] != null)
        {
            if (sourceFiles[i].Trim() != "")

As first step after any changes, I use ng build, then ng serve. It works without any problems.

and add method

focusNextField(nextField) {
    this.refs[nextField].focus();
}

You can do this with numpy's argsort method if you have numpy available:

>>> import numpy
>>> vals = numpy.array([2,3,1,4,5])
>>> vals
array([2, 3, 1, 4, 5])
>>> sort_index = numpy.argsort(vals)
>>> sort_index
array([2, 0, 1, 3, 4])

If not available, taken from this question, this is the fastest method:

>>> vals = [2,3,1,4,5]
>>> sorted(range(len(vals)), key=vals.__getitem__)
[2, 0, 1, 3, 4]

I had the same problem but also wanted to get the content of the file (after the YAML front-matter).

This is the best solution I have found:

if (md = contents.match(/^(?<metadata>---\s*\n.*?\n?)^(---\s*$\n?)/m))
  self.contents = md.post_match
  self.metadata = YAML.load(md[:metadata])
end

I think you are referring to the problem in C (and C++) that returning an array from a function isn't allowed (or at least won't work as expected) - this is because the array return will (if you write it in the simple form) return a pointer to the actual array on the stack, which is then promptly removed when the function returns.

But in this case, it works, because the std::vector is a class, and classes, like structs, can (and will) be copied to the callers context. [Actually, most compilers will optimise out this particular type of copy using something called "Return Value Optimisation", specifically introduced to avoid copying large objects when they are returned from a function, but that's an optimisation, and from a programmers perspective, it will behave as if the assignment constructor was called for the object]

As long as you don't return a pointer or a reference to something that is within the function returning, you are fine.

On a side note, it would have been much easier to just do this.

You could parse the output from the GPRESULT command.

The sep='\t' can be use in many forms, for example if you want to read tab separated value: Example: I have a dataset tsv = tab separated value NOT comma separated value df = pd.read_csv('gapminder.tsv'). when you try to read this, it will give you an error because you have tab separated value not csv. so you need to give read csv a different parameter called sep='\t'.

Now you can read: df = pd.read_csv('gapminder.tsv, sep='\t'), with this you can read the it.

The Problem to push mostly is because of the size of the files that need to be pushed. I was trying to push some libraries of just size 2 mb, then too the push was giving error of RPC with result 7. The line is of 4 mbps and is working fine. Some subsequent tries to the push got me success. If such error comes, wait for few minutes and keep on trying.

I also found out that there are some RPC failures if the github is down or is getting unstable network at their side.

So keeping up trying after some intervals is the only option!

You can center float div with this little code:

#div {
    width: 200px;
    height: 200px;
    position: absolute;
    left: 50%;
    top: 50%;
    
    margin-top: -100px;
    margin-left: -100px;
}

You have by default the static endpoint for static files. Also Flask application has the following arguments:

static_url_path: can be used to specify a different path for the static files on the web. Defaults to the name of the static_folder folder.

static_folder: the folder with static files that should be served at static_url_path. Defaults to the 'static' folder in the root path of the application.

It means that the filename argument will take a relative path to your file in static_folder and convert it to a relative path combined with static_url_default:

url_for('static', filename='path/to/file')

will convert the file path from static_folder/path/to/file to the url path static_url_default/path/to/file.

So if you want to get files from the static/bootstrap folder you use this code:

<link rel="stylesheet" type="text/css" href="{{ url_for('static', filename='bootstrap/bootstrap.min.css') }}">

Which will be converted to (using default settings):

<link rel="stylesheet" type="text/css" href="static/bootstrap/bootstrap.min.css">

Also look at url_for documentation.

You can't stop a timer function mid-execution. You can only catch it after it completes and prevent it from triggering again.

I believe the intent was to rename System32, but so many applications hard-coded for that path, that it wasn't feasible to remove it.

SysWoW64 wasn't intended for the dlls of 64-bit systems, it's actually something like "Windows on Windows64", meaning the bits you need to run 32bit apps on a 64bit windows.

This article explains a bit:

"Windows x64 has a directory System32 that contains 64-bit DLLs (sic!). Thus native processes with a bitness of 64 find “their” DLLs where they expect them: in the System32 folder. A second directory, SysWOW64, contains the 32-bit DLLs. The file system redirector does the magic of hiding the real System32 directory for 32-bit processes and showing SysWOW64 under the name of System32."

Edit: If you're talking about an installer, you really should not hard-code the path to the system folder. Instead, let Windows take care of it for you based on whether or not your installer is running on the emulation layer.

You can simply convert long string into integer by using FLOAT

$float = (float)$num;

Or if you want integer not floating val then go with

$float = (int)$num;

For ex.

(int)   "1212.3"   = 1212 
(float) "1212.3"   = 1212.3

Windows-> Start -> Turn widows features on and off

Make sure you check required options in

Quite often the issue is a non-breaking space - CHAR(160) - especially from Web text sources -that CLEAN can't remove, so I would go a step further than this and try a formula like this which replaces any non-breaking spaces with a standard one

=TRIM(CLEAN(SUBSTITUTE(A1,CHAR(160)," ")))

Ron de Bruin has an excellent post on tips for cleaning data here

You can also remove the CHAR(160) directly without a workaround formula by

• Edit .... Replace your selected data,
• in Find What hold ALT and type 0160 using the numeric keypad
• Leave Replace With as blank and select Replace All

How to use `while read` (Bash) to read the last line in a file if there’s no newline at the end of the file?

Python sequence slice addresses can be written as a[start:end:step] and any of start, stop or end can be dropped. a[::3] is every third element of the sequence.

Here's a Boolean thing:

if (not suffix == "flac" )  or (not suffix == "cue" ):   # WRONG! FAILS
    print  filename + ' is not a flac or cue file'

but

if not (suffix == "flac"  or suffix == "cue" ):     # CORRECT!
       print  filename + ' is not a flac or cue file'

(not a) or (not b) == not ( a and b ) , is false only if a and b are both true

not (a or b) is true only if a and be are both false.

Just to correct mingos' answer:

If you set the expiration time to 0, the cookie won't be created at all. I've tested this on Google Chrome at least, and when set to 0 that was the result. The cookie, I guess, expires immediately after creation.

To set a cookie so it expires at the end of the browsing session, simply OMIT the expiration parameter altogether.

Example:

Instead of:

document.cookie = "cookie_name=cookie_value; 0; path=/";

Just write:

document.cookie = "cookie_name=cookie_value; path=/";

This may work as well.

No, is not possible to downgrade a database. 10.50.1600 is the SQL Server 2008 R2 version. There is absolutely no way you can restore or attach this database to the SQL Server 2008 instance you are trying to restore on (10.00.1600 is SQL Server 2008). Your only options are:

• upgrade this instance to SQL Server 2008 R2 or
• restore the backup you have on a SQL Server 2008 R2 instance, export all the data and import it on a SQL Server 2008 database.

How to debug Windows Script Host, VBScript, and JScript files

SUMMARY

The purpose of this article is to explain how to debug Windows Script Host (WSH) scripts, which can be written in any ActiveX script language (as long as the proper language engine is installed), but which, by default, are written in VBScript and JScript. There are certain flags in the registry and, depending on the debugger used, certain required procedures to enable debugging.

MORE INFORMATION

To debug WSH scripts in Microsoft Visual InterDev, the Microsoft Script Debugger, or any other debugger, use the following command-line syntax to start the script:

wscript.exe //d <path to WSH file>
           This code informs the user when a runtime error has occurred and gives the user a choice to debug the application. Also, the //x flag

can be used, as follows, to throw an immediate exception, which starts the debugger immediately after the script starts running:

wscript.exe //d //x <path to WSH file>
           After a debug condition exists, the following registry key determines which debugger will be used:

HKEY_CLASSES_ROOT\CLSID\{834128A2-51F4-11D0-8F20-00805F2CD064}\LocalServer32

The script debugger should be Msscrdbg.exe, and the Visual InterDev debugger should be Mdm.exe.

If Visual InterDev is the default debugger, make sure that just-in-time (JIT) functionality is enabled. To do this, follow these steps:

1. Start Visual InterDev.

2. On the Tools menu, click Options.

3. Click Debugger, and then ensure that the Just-In-Time options are selected for both the General and Script categories.

Additionally, if you are trying to debug a .wsf file, make sure that the following registry key is set to 1:

HKEY_CURRENT_USER\Software\Microsoft\Windows Script\Settings\JITDebug

For a normal string you can use:

int number = Integer.parseInt("1234");

For a String builder and String buffer you can use:

Integer.parseInt(myBuilderOrBuffer.toString());

If input datetime object is in UTC:

>>> dt = datetime(2008, 1, 1, 0, 0, 0, 0)
>>> timestamp = (dt - datetime(1970, 1, 1)).total_seconds()
1199145600.0

Note: it returns float i.e., microseconds are represented as fractions of a second.

If input date object is in UTC:

>>> from datetime import date
>>> utc_date = date(2008, 1, 1)
>>> timestamp = (utc_date.toordinal() - date(1970, 1, 1).toordinal()) * 24*60*60
1199145600

See more details at Converting datetime.date to UTC timestamp in Python.

I needed to solve this problem too a while back so that I could act as a client for a RESTful API. I settled on httplib2 because it allowed me to send PUT and DELETE in addition to GET and POST. Httplib2 is not part of the standard library but you can easily get it from the cheese shop.

runAllManagedModulesForAllRequests=true is actually a real bad solution. This increased the load time of my application by 200%. The better solution is to manually remove and add the session object and to avoid the run all managed modules attribute all together.

Received SQLSTATE 01000 in the following error message below:

SQL Agent - Jobs Failed: The SQL Agent Job "LiteSpeed Backup Full" has failed with the message "The job failed. The Job was invoked by User X. The last step to run was step 1 (Step1). NOTE: Failed to notify via email. - Executed as user: X. LiteSpeed(R) for SQL Server Version 6.5.0.1460 Copyright 2011 Quest Software, Inc. [SQLSTATE 01000] (Message 1) LiteSpeed for SQL Server could not open backup file: (N:\BACKUP2\filename.BAK). The previous system message is the reason for the failure. [SQLSTATE 42000] (Error 60405). The step failed."

In my case this was related to permission on drive N following an SQL Server failover on an Active/Passive SQL cluster.

All SQL resources where failed over to the seconary resouce and back to the preferred node following maintenance. When the Quest LiteSpeed job then executed on the preferred node it was clear the previous permissions for SQL server user X had been lost on drive N and SQLSTATE 10100 was reported.

Simply added the permissions again to the backup destination drive and the issue was resolved.

Hope that helps someone.

<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>

That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em' as the measurement, you may want to use other units, like 'px'.

EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:

In your HTML page, containing the <p> tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:

<head>
  <style type="text/css">
    p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>

So above, all <p> elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:

<head>
  <style type="text/css">
    .container p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <div class="container">
    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
  </div>
  <p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>

In the example above, only the <p> element inside the div, whose class name is 'container', will have the styles applied - and not the <p> element outside the container.

In addition to the above, you can collect your styles together and remove the style element from the <head> tag, replacing it with a <link> tag, which points to an external CSS file. This external file is where you'd now put your <p> tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.

The issue could be with the response you are receiving from back-end. If it was working fine on the server then the problem could be with the response headers. Check the Access-Control-Allow-Origin (ACAO) in the response headers. Usually react's fetch API will throw fail to fetch even after receiving response when the response headers' ACAO and the origin of request won't match.

Goto View -> Show Symbol -> Show All Characters. Uncheck it. There you go.!!

You are setting the response headers after writing the contents of the file to the output stream. This is quite late in the response lifecycle to be setting headers. The correct sequence of operations should be to set the headers first, and then write the contents of the file to the servlet's outputstream.

Therefore, your method should be written as follows (this won't compile as it is a mere representation):

response.setContentType("application/force-download");
response.setContentLength((int)f.length());
        //response.setContentLength(-1);
response.setHeader("Content-Transfer-Encoding", "binary");
response.setHeader("Content-Disposition","attachment; filename=\"" + "xxx\"");//fileName);
...
...
File f= new File(fileName);

InputStream in = new FileInputStream(f);
BufferedInputStream bin = new BufferedInputStream(in);
DataInputStream din = new DataInputStream(bin);

while(din.available() > 0){
    out.print(din.readLine());
    out.print("\n");
}

The reason for the failure is that it is possible for the actual headers sent by the servlet would be different from what you are intending to send. After all, if the servlet container does not know what headers (which appear before the body in the HTTP response), then it may set appropriate headers to ensure that the response is valid; setting the headers after the file has been written is therefore futile and redundant as the container might have already set the headers. You could confirm this by looking at the network traffic using Wireshark or a HTTP debugging proxy like Fiddler or WebScarab.

You may also refer to the Java EE API documentation for ServletResponse.setContentType to understand this behavior:

Sets the content type of the response being sent to the client, if the response has not been committed yet. The given content type may include a character encoding specification, for example, text/html;charset=UTF-8. The response's character encoding is only set from the given content type if this method is called before getWriter is called.

This method may be called repeatedly to change content type and character encoding. This method has no effect if called after the response has been committed.

The answer provided by Joe Stefanelli is already correct.

SELECT name FROM (SELECT name FROM agentinformation) as a  

We need to make an alias of the subquery because a query needs a table object which we will get from making an alias for the subquery. Conceptually, the subquery results are substituted into the outer query. As we need a table object in the outer query, we need to make an alias of the inner query.

Statements that include a subquery usually take one of these forms:

• WHERE expression [NOT] IN (subquery)
• WHERE expression comparison_operator [ANY | ALL] (subquery)
• WHERE [NOT] EXISTS (subquery)

Check for more subquery rules and subquery types.

More examples of Nested Subqueries.

1. IN / NOT IN – This operator takes the output of the inner query after the inner query gets executed which can be zero or more values and sends it to the outer query. The outer query then fetches all the matching [IN operator] or non matching [NOT IN operator] rows.

2. ANY – [>ANY or ANY operator takes the list of values produced by the inner query and fetches all the values which are greater than the minimum value of the list. The

e.g. >ANY(100,200,300), the ANY operator will fetch all the values greater than 100.

3. ALL – [>ALL or ALL operator takes the list of values produced by the inner query and fetches all the values which are greater than the maximum of the list. The

e.g. >ALL(100,200,300), the ALL operator will fetch all the values greater than 300.

4. EXISTS – The EXISTS keyword produces a Boolean value [TRUE/FALSE]. This EXISTS checks the existence of the rows returned by the sub query.

ISO compliant dateString

If your dateString is RFC282 and ISO8601 compliant:
pass your string into the Date Constructor:

const dateString = "2020-10-30T12:52:27+05:30"; // ISO8601 compliant dateString
const D = new Date(dateString);                 // {object Date}

from here you can extract the desired values by using Date Getters:

D.getMonth() + 1  // 10 (PS: +1 since Month is 0-based)
D.getDate()       // 30
D.getFullYear()   // 2020

Non-standard date string

If you use a non standard date string:
destructure the string into known parts, and than pass the variables to the Date Constructor:

new Date(year, monthIndex [, day [, hours [, minutes [, seconds [, milliseconds]]]]])

const dateString = "30/10/2020 12:52:27";
const [d, M, y, h, m, s] = dateString.match(/\d+/g);

// PS: M-1 since Month is 0-based
const D = new Date(y, M-1, d, h, m, s);  // {object Date}


D.getMonth() + 1  // 10 (PS: +1 since Month is 0-based)
D.getDate()       // 30
D.getFullYear()   // 2020

I am using bootstrap calender for future date not allow with allow change in months & year only..

        j(function () {
            j(".datepicker").datepicker({ dateFormat: "dd-M-yy" }).val()
        });

        j(function () {
            j(".Futuredatenotallowed").datepicker({
                changeMonth: true,
                maxDate: 0,
                changeYear: true,
                dateFormat: 'dd-M-yy',
                language: "tr"
            }).on('changeDate', function (ev) {
                $(this).blur();
                $(this).datepicker('hide');
            }).val()
        });

The same problem arrised for me when I installed Kaliko CMS Nuget Package. When I removed it, it started working fine again. So, your problem could be because of a recently installed Nuget Package. Uninstall it and your solution will work just fine.

A REST API is an API implementation that adheres to the REST architectural constraints. It acts as an interface. The communication between the client & the server happens over HTTP. A REST API takes advantage of the HTTP methodologies to establish communication between the client and the server. REST also enables servers to cache the response that improves the performance of the application. The communication between the client and the server is a stateless process. And by that, I mean every communication between the client and the server is like a new one.

There is no information or memory carried over from the previous communications. So, every time a client interacts with the backend, it has to send the authentication information to it as well. This enables the backend to figure out that the client is authorized to access the data or not.

With the implementation of a REST API the client gets the backend endpoints to communicate with. This entirely decouples the backend & the client code.

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

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

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

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

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

<div id="bodyDummy">

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

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

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

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

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

For cloning the objects as well I was just going to suggest ECMAScript 6 reduce():

const newArray=myArray.reduce((array, element)=>array.push(Object.assign({}, element)), []);

But frankly I like the answer of @dinodsaurus even better. I'm just putting this version here as another option, but personally I'll be using map() as suggested by @dinodsaurus .

Let eclipse use your java vm directly!

Put these lines at the end of eclipse.ini (located in the directory where eclipse.exe is present):

-vm
<your path to jdk|jre>/bin/javaw.exe

Pay attention that there are two lines. Also make sure that the -vm option is before the -vmargs option (and of course after "openFile").

Useful link Eclispe.ini at wiki.eclipse.org

Just as an alternative:

1. In the folder you are going to search the PATH variable for, create a temporary file with such an unusual name that you would never ever expect any other file on your computer to have.

2. Use the standard batch scripting construct that lets you perform the search for a file by looking up a directory list defined by some environment variable (typically PATH).

3. Check if the result of the search matches the path in question, and display the outcome.

4. Delete the temporary file.

This might look like this:

@ECHO OFF
SET "mypath=D:\the\searched-for\path"
SET unusualname=nowthisissupposedtobesomeveryunusualfilename
ECHO.>"%mypath%\%unusualname%"
FOR %%f IN (%unusualname%) DO SET "foundpath=%%~dp$PATH:f"
ERASE "%mypath%\%unusualname%"
IF "%mypath%" == "%foundpath%" (
  ECHO The dir exists in PATH
) ELSE (
  ECHO The dir DOES NOT exist in PATH
)

Known issues:

1. The method can work only if the directory exists (which isn't always the case).

2. Creating / deleting files in a directory affects its 'modified date/time' attribute (which may be an undesirable effect sometimes).

3. Making up a globally unique file name in one's mind cannot be considered very reliable. Generating such a name is itself not a trivial task.

(I presume that you've concluded that it's an iptables problem by dropping the firewall completely (iptables -P INPUT ACCEPT; iptables -P OUTPUT ACCEPT; iptables -F) and confirmed that you can connect to the MySQL server from your Windows box?)

Some previous rule in the INPUT table is probably rejecting or dropping the packet. You can get around that by inserting the new rule at the top, although you might want to review your existing rules to see whether that's sensible:

iptables -I INPUT 1 -p tcp --dport 3306 -j ACCEPT

Note that iptables-save won't save the new rule persistently (i.e. across reboots) - you'll need to figure out something else for that. My usual route is to store the iptables-save output in a file (/etc/network/iptables.rules or similar) and then load then with a pre-up statement in /etc/network/interfaces).

when you set the density to 96, doesn't it look good?

when i tried it i saw that saving as jpg resulted with better quality, but larger file size

(Alt + Shift + X) , then M to Run Maven Build. You will need to specify the Maven goals you want on Run -> Run Configurations

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

My StreamEx library which enhances the Java 8 streams provides a special operation distinct(atLeast) which can retain only elements appearing at least the specified number of times. So your problem can be solved like this:

List<Integer> repeatingNumbers = StreamEx.of(numbers).distinct(2).toList();

Internally it's similar to @Dave solution, it counts objects, to support other wanted quantities and it's parallel-friendly (it uses ConcurrentHashMap for parallelized stream, but HashMap for sequential). For big amounts of data you can get a speed-up using .parallel().distinct(2).

I sometimes print debugging output to the browser window. Using jQuery, you could send output messages to a display area on your page:

<div id='display'></div>

$('#display').text('array length: ' + myArray.length);

Or if you want to watch JavaScript variables without adding a display area to your page:

function debug(txt) {
    $('body').append("<div style='width:300px;background:orange;padding:3px;font-size:13px'>" + txt + "</div>");
}

I didn't read all the posts but every answer seems to be missing one concept that really helped me "get it"...

If a Model is akin to a database Table, then a ViewModel is akin to a database View - A view typically either returns small amounts of data from one table, or, complex sets of data from multiple tables (joins).

I find myself using ViewModels to pass info into a view/form, and then transfering that data into a valid Model when the form posts back to the controller - also very handy for storing Lists(IEnumerable).

I recently had this same problem. Unfortunately, NotifyIcon is only a Windows.Forms control at the moment, if you want to use it you are going to have to include that part of the framework. I guess that depends how much of a WPF purist you are.

If you want a quick and easy way of getting started check out this WPF NotifyIcon control on the Code Project which does not rely on the WinForms NotifyIcon at all. A more recent version seems to be available on the author's website and as a NuGet package. This seems like the best and cleanest way to me so far.

• Rich ToolTips rather than text
• WPF context menus and popups
• Command support and routed events
• Flexible data binding
• Rich balloon messages rather than the default messages provides by the OS

Check it out. It comes with an amazing sample app too, very easy to use, and you can have great looking Windows Live Messenger style WPF popups, tooltips, and context menus. Perfect for displaying an RSS feed, I am using it for a similar purpose.

create a vbs file and copy all code below. Change directory location to wherever you want.

Dim fso
Dim ObjOutFile

Set fso = CreateObject("Scripting.FileSystemObject")

Set ObjOutFile = fso.CreateTextFile("OutputFiles.csv")

ObjOutFile.WriteLine("Type,File Name,File Path")

GetFiles("YOUR LOCATION")

ObjOutFile.Close

WScript.Echo("Completed")

Function GetFiles(FolderName)
    On Error Resume Next

    Dim ObjFolder
    Dim ObjSubFolders
    Dim ObjSubFolder
    Dim ObjFiles
    Dim ObjFile

    Set ObjFolder = fso.GetFolder(FolderName)
    Set ObjFiles = ObjFolder.Files

    For Each ObjFile In ObjFiles
    ObjOutFile.WriteLine("File," & ObjFile.Name & "," & ObjFile.Path)
    Next

    Set ObjSubFolders = ObjFolder.SubFolders

    For Each ObjFolder In ObjSubFolders

        ObjOutFile.WriteLine("Folder," & ObjFolder.Name & "," & ObjFolder.Path)


        GetFiles(ObjFolder.Path)
    Next

End Function

Save the code as vbs and run it. you will get a list in that directory

As far as I know, there is no general library in this context to be suitable for all types of problems. So, for each problem you should test the existing libraries and select the best one which satisfies your problem’s constraints, but often none of them is appropriate. In these cases you can write your own Encoding Detector! As I have wrote ...

I’ve wrote a meta java tool for detecting charset encoding of HTML Web pages, using IBM ICU4j and Mozilla JCharDet as the built-in components. Here you can find my tool, please read the README section before anything else. Also, you can find some basic concepts of this problem in my paper and in its references.

Bellow I provided some helpful comments which I’ve experienced in my work:

• Charset detection is not a foolproof process, because it is essentially based on statistical data and what actually happens is guessing not detecting
• icu4j is the main tool in this context by IBM, imho
• Both TikaEncodingDetector and Lucene-ICU4j are using icu4j and their accuracy had not a meaningful difference from which the icu4j in my tests (at most %1, as I remember)
• icu4j is much more general than jchardet, icu4j is just a bit biased to IBM family encodings while jchardet is strongly biased to utf-8
• Due to the widespread use of UTF-8 in HTML-world; jchardet is a better choice than icu4j in overall, but is not the best choice!
• icu4j is great for East Asian specific encodings like EUC-KR, EUC-JP, SHIFT_JIS, BIG5 and the GB family encodings
• Both icu4j and jchardet are debacle in dealing with HTML pages with Windows-1251 and Windows-1256 encodings. Windows-1251 aka cp1251 is widely used for Cyrillic-based languages like Russian and Windows-1256 aka cp1256 is widely used for Arabic
• Almost all encoding detection tools are using statistical methods, so the accuracy of output strongly depends on the size and the contents of the input
• Some encodings are essentially the same just with a partial differences, so in some cases the guessed or detected encoding may be false but at the same time be true! As about Windows-1252 and ISO-8859-1. (refer to the last paragraph under the 5.2 section of my paper)

Oskar Persson's answer is the best way to handle it because makes it easier to pass the data to the context and treat it normally from the template as we get the object instances (easily iterable to get props) instead of a plain value list.

After that you can just easily get the wanted prop:

for employee in employees:
    print(employee.eng_name)

Or in the template:

{% for employee in employees %}

    <p>{{ employee.eng_name }}</p>

{% endfor %}

#!/bin/bash
#
# Change the file name from "test" to desired input file 
# (The comments in bash are prefixed with #'s)
for x in $(cat test.txt)
do
    echo $x
done

What is a GUID?

GUID (or UUID) is an acronym for 'Globally Unique Identifier' (or 'Universally Unique Identifier'). It is a 128-bit integer number used to identify resources. The term GUID is generally used by developers working with Microsoft technologies, while UUID is used everywhere else.

How unique is a GUID?

128-bits is big enough and the generation algorithm is unique enough that if 1,000,000,000 GUIDs per second were generated for 1 year the probability of a duplicate would be only 50%. Or if every human on Earth generated 600,000,000 GUIDs there would only be a 50% probability of a duplicate.

Javadocs don't offer any special tools for external links, so you should just use standard html:

See <a href="http://groversmill.com/">Grover's Mill</a> for a history of the
Martian invasion.

or

@see <a href="http://groversmill.com/">Grover's Mill</a> for a history of 
the Martian invasion.

Don't use {@link ...} or {@linkplain ...} because these are for links to the javadocs of other classes and methods.

$('.checkbox').prop('checked',true); 
$('.checkbox').prop('checked',false);

... works perfectly with jquery1.9.1

Just had a look at the DOM (document.scripts[1].attributes) of this page that uses google analytics. I can tell you that google is using async="".

[type="text/javascript", async="", src="http://www.google-analytics.com/ga.js"]

<select name="aa" onchange="report(this.value)"> 
  <option value="">Please select</option>
  <option value="daily">daily</option>
  <option value="monthly">monthly</option>
</select>

using

function report(period) {
  if (period=="") return; // please select - possibly you want something else here

  const report = "script/"+((period == "daily")?"d":"m")+"_report.php";
  loadXMLDoc(report,'responseTag');
  document.getElementById('responseTag').style.visibility='visible';
  document.getElementById('list_report').style.visibility='hidden';
  document.getElementById('formTag').style.visibility='hidden'; 
} 

Unobtrusive version:

<select id="aa" name="aa"> 
  <option value="">Please select</option>
  <option value="daily">daily</option>
  <option value="monthly">monthly</option>
</select>

using

window.addEventListener("load",function() {
  document.getElementById("aa").addEventListener("change",function() {
    const period = this.value;
    if (period=="") return; // please select - possibly you want something else here

    const report = "script/"+((period == "daily")?"d":"m")+"_report.php";
    loadXMLDoc(report,'responseTag');
    document.getElementById('responseTag').style.visibility='visible';
    document.getElementById('list_report').style.visibility='hidden';
    document.getElementById('formTag').style.visibility='hidden'; 
  }); 
});

jQuery version - same select with ID

$(function() {
  $("#aa").on("change",function() {
    const period = this.value;
    if (period=="") return; // please select - possibly you want something else here

    var report = "script/"+((period == "daily")?"d":"m")+"_report.php";
    loadXMLDoc(report,'responseTag');
    $('#responseTag').show();
    $('#list_report').hide();
    $('#formTag').hide(); 
  }); 
});

AppCompat tinting attributs:

First, you should take a look to appCompat lib article there and to different attributs you can set:

colorPrimary: The primary branding color for the app. By default, this is the color applied to the action bar background.

colorPrimaryDark: Dark variant of the primary branding color. By default, this is the color applied to the status bar (via statusBarColor) and navigation bar (via navigationBarColor).

colorAccent: Bright complement to the primary branding color. By default, this is the color applied to framework controls (via colorControlActivated).

colorControlNormal: The color applied to framework controls in their normal state.

colorControlActivated: The color applied to framework controls in their activated (ex. checked, switch on) state.

colorControlHighlight: The color applied to framework control highlights (ex. ripples, list selectors).

colorButtonNormal: The color applied to framework buttons in their normal state.

colorSwitchThumbNormal: The color applied to framework switch thumbs in their normal state. (switch off)

If all custom switches are the same in a single activity:

With previous attributes you can define your own theme for each activity:

<style name="Theme.MyActivityTheme" parent="Theme.AppCompat.Light">
    <!-- colorPrimary is used for the default action bar background -->
    <item name="colorPrimary">@color/my_awesome_color</item>

    <!-- colorPrimaryDark is used for the status bar -->
    <item name="colorPrimaryDark">@color/my_awesome_darker_color</item>

    <!-- colorAccent is used as the default value for colorControlActivated,
         which is used to tint widgets -->
    <item name="colorAccent">@color/accent</item>

    <!-- You can also set colorControlNormal, colorControlActivated
         colorControlHighlight, and colorSwitchThumbNormal. -->

</style>

and :

<manifest>
...
    <activity
        android:name=".MainActivity" 
        android:theme="@style/Theme.MyActivityTheme">
    </activity>
...
</manifest>

If you want to have differents custom switches in a single activity:

As widget tinting in appcompat works by intercepting any layout inflation and inserting a special tint-aware version of the widget in its place (See Chris Banes post about it) you can not apply a custom style to each switch of your layout xml file. You have to set a custom Context that will tint switch with right colors.

--

To do so for pre-5.0 you need to create a Context that overlays global theme with customs attributs and then create your switches programmatically:

ContextThemeWrapper ctw = ContextThemeWrapper(getActivity(), R.style.Color1SwitchStyle); 
SwitchCompat sc = new SwitchCompat(ctw)

As of AppCompat v22.1 you can use the following XML to apply a theme to the switch widget:

<RelativeLayout
    xmlns:app="http://schemas.android.com/apk/res-auto"
    ...>

    <android.support.v7.widget.SwitchCompat
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:theme="@style/Color1SwitchStyle"/>

Your custom switch theme:

<style name="Color1SwitchStyle">
    <item name="colorControlActivated">@color/my_awesome_color</item>
</style>

--

On Android 5.0 it looks like a new view attribut comes to life : android:theme (same as one use for activity declaration in manifest). Based on another Chris Banes post, with the latter you should be able to define a custom theme directly on a view from your layout xml:

<android.support.v7.widget.SwitchCompat
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/Color1SwitchStyle"/>

To change the track color of a SwitchCompat

Thanks to vine'th I complete my answer with a link to SO answer that explains how to specify the Foreground of the Track when Switch is Off, it's there.

Submodule repositories stay in a detached HEAD state pointing to a specific commit. Changing that commit simply involves checking out a different tag or commit then adding the change to the parent repository.

$ cd submodule
$ git checkout v2.0
Previous HEAD position was 5c1277e... bumped version to 2.0.5
HEAD is now at f0a0036... version 2.0

git-status on the parent repository will now report a dirty tree:

# On branch dev [...]
#
#   modified:   submodule (new commits)

Add the submodule directory and commit to store the new pointer.

Yes, it is possible.

try:
   ...
except FirstException:
   handle_first_one()

except SecondException:
   handle_second_one()

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

except Exception:
   handle_all_other_exceptions()

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

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

jQuery is just a set of helpers/libraries written in Javascript. You can still use all Javascript features, so you can call whatever functions, also from inside jQuery callbacks. So both possibilities should be okay.

I had a similar issue recently which turned out to be due to ssl_ciphers that I was using.

From http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/RequestAndResponseBehaviorCustomOrigin.html,

"CloudFront forwards HTTPS requests to the origin server using the SSLv3 or TLSv1 protocols and the AES128-SHA1 or RC4-MD5 ciphers. If your origin server does not support either the AES128-SHA1 or RC4-MD5 ciphers, CloudFront cannot establish an SSL connection to your origin. "

I had to change my nginx confg to add AES128-SHA ( deprecated RC4:HIGH ) to ssl_ciphers to fix the 302 error. I hope this helps. I have pasted the line from my ssl.conf

ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:DH+3DES:RSA+3DES:AES128-SHA:!ADH:!AECDH:!MD5;

Check out this site: http://rubular.com/ Basically the site allows you to enter some example text (what you would be looking for on your site) and then as you build the regular expression it will highlight what is being matched in real time.

A scenario which I sometimes run into:

Assume you have a trunk, from which you created a release branch. After some changes on trunk (in particular creating "some-dir" directory), you create a feature/fix branch which you want later merge into release branch as well (because changes were small enough and the feature/fix is important for release).

trunk -- ... -- create "some-dir" -- ...
     \                                  \-feature/fix branch
      \- release branch

If you then try to merge the feature/fix branch directly into the release branch you will get a tree conflict (even though the directory did not even exist in feature/fix branch):

svn status
!     C some-dir
      >   local missing or deleted or moved away, incoming file edit upon merge

So you need to explicitly merge the commits which were done on trunk before creating feature/fix branch which created the "some-dir" directory before merging the feature/fix branch.

I often forget that as that is not necessary in git.

It works for me:

$('#yourselect').on("change", function(e) { 
   // what you would like to happen
});

The second time you're referring to div2, you're not using the # id selector.

There's no element named div2.

Inner join matches tables on keys, but outer join matches keys just for one side. For example when you use left outer join the query brings the whole left side table and matches the right side to the left table primary key and where there is not matched places null.

Remove the existing precompiled files:

rm -rf  /Users/raghu/Library/Developer/Xcode/DerivedData/Solitare-fdaukpanamlzllacxvdzfbeqcrsg/

And try to build it again.

you can run raw query like this way too.

DB::table('setting_colleges')->first();

This did it for me (the second answer): Why are my PHP files showing as plain text?

Simply adding this, nothing else worked.

apt-get install libapache2-mod-php5

If you want to install ASP.NET MVC 5 and ASP.NET Web API 2 into VS 2012 Ultimage so, you can download MSI installer from
http://www.microsoft.com/en-us/download/details.aspx?id=41532.

I have downloaded and intalled just know. I got MVC 5 and Web API 2
:)

I would do it like this:

$('body').on('hidden.bs.modal', '#myModal', function(){ //this call your method });

The rest has already been written by others. I also recommend reading the documentation:jquery - on method

The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.

If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.

For angular 8 and Firebase 6 you can use the option id field

      getAllDocs() {
           const ref = this.db.collection('items');
           return ref.valueChanges({idField: 'customIdName'});
      }

this adds the Id of the document on the object with a specified key (customIdName)

Answering my own question here... turns out it's a Windows only quirk that happens when reading binary files (in my case a JPEG) that requires an additional flag in the open or File.open function call. I revised it to open("/path/to/file", 'rb') {|io| a = a + io.read} and all was fine.

Step1: open ~/.bash_profile

Now a text editor opens:

Step2: variable name should be in capitals. in this example variable is NODE_ENV

Step3: export NODE_ENV=development

Save it and close.

Restart your system.

Done.

To check env variable: open terminal and type

echo $NODE_ENV 

Not too sure to add opacity via CSS is such a good idea.
Opacity has that funny way to be applied to all content and childs from where you set it, with unexpected results in mixed of colours.
It has no really purpose in that case , for a bg color, in my opinion.
If you'd like to lay it hover the bg image, then you may use multiple backgrounds.
this color transparent could be applyed via an extra png repeated (or not with background-position),
CSS gradient (radial-) linear-gradient with rgba colors (starting and ending with same color) can achieve this as well. They are treated as background-image and can be used as filter.
Idem for text, if you want them a bit transparent, use rgba (okay to put text-shadow together).

I think that today, we can drop funny behavior of CSS opacity.

Here is a mixed of rgba used for opacity if you are curious dabblet.com/gist/5685845

Ken had it right as well.

a css tag:

audio {

}

will get you some results. seems it doesnt want the player any height above or below 25px but the width can be shortened or lengthened to an extent.

this was good enough for me; see this example (warning, audio plays automatically): www.thenewyorkerdeliinc.com

You can set padding to your view by pro grammatically throughout below code -

view.setPadding(0,1,20,3);

And, also there are different type of padding available -

PaddingLeft

PaddingRight

PaddingTop

I'm am very disappointed by the accepted answers in this question. This will not scale. If you read the fine print on cursor.skip( ):

The cursor.skip() method is often expensive because it requires the server to walk from the beginning of the collection or index to get the offset or skip position before beginning to return result. As offset (e.g. pageNumber above) increases, cursor.skip() will become slower and more CPU intensive. With larger collections, cursor.skip() may become IO bound.

To achieve pagination in a scaleable way combine a limit( ) along with at least one filter criterion, a createdOn date suits many purposes.

MyModel.find( { createdOn: { $lte: request.createdOnBefore } } )
.limit( 10 )
.sort( '-createdOn' )

In Python, the 'null' object is the singleton None.

The best way to check things for "Noneness" is to use the identity operator, is:

if foo is None:
    ...

I am aware there are existing answers which solves the problem. For those who are new to git, As of 02/11/2021, The default branch in git is "main" not "master" branch, The command will be

git push -u origin main

Unfortunately the link in the exception text, http://go.microsoft.com/fwlink/?LinkId=70353, is broken. However, it used to lead to http://msdn.microsoft.com/en-us/library/ms733768.aspx which explains how to set the permissions.

It basically informs you to use the following command:

netsh http add urlacl url=http://+:80/MyUri user=DOMAIN\user

You can get more help on the details using the help of netsh

For example: netsh http add ?

Gives help on the http add command.

There's another, very secure method. It's client certificates. Know how servers present an SSL Cert when you contact them on https? Well servers can request a cert from a client so they know the client is who they say they are. Clients generate certs and give them to you over a secure channel (like coming into your office with a USB key - preferably a non-trojaned USB key).

You load the public key of the cert client certificates (and their signer's certificate(s), if necessary) into your web server, and the web server won't accept connections from anyone except the people who have the corresponding private keys for the certs it knows about. It runs on the HTTPS layer, so you may even be able to completely skip application-level authentication like OAuth (depending on your requirements). You can abstract a layer away and create a local Certificate Authority and sign Cert Requests from clients, allowing you to skip the 'make them come into the office' and 'load certs onto the server' steps.

Pain the neck? Absolutely. Good for everything? Nope. Very secure? Yup.

It does rely on clients keeping their certificates safe however (they can't post their private keys online), and it's usually used when you sell a service to clients rather then letting anyone register and connect.

Anyway, it may not be the solution you're looking for (it probably isn't to be honest), but it's another option.

I use a slightly more concise version:

expect(() => {
  // Code block that should throw error
}).toThrow(TypeError) // Or .toThrow('expectedErrorMessage')

You can use the simple mailto, see below for the simple markup.

<a href="mailto:[email protected]">Click here to mail</a>

Once clicked, it will open your Outlook or whatever email client you have set.

IMHO the best option is to use YAML's native block scalars. Specifically in this case, the folded style block.

By invoking sh -c you can pass arguments to your container as commands, but if you want to elegantly separate them with newlines, you'd want to use the folded style block, so that YAML will know to convert newlines to whitespaces, effectively concatenating the commands.

A full working example:

apiVersion: v1
kind: Pod
metadata:
  name: myapp
  labels:
    app: myapp
spec:
  containers:
  - name: busy
    image: busybox:1.28
    command: ["/bin/sh", "-c"]
    args:
    - >
      command_1 &&
      command_2 &&
      ... 
      command_n

This works because the it's a static variable. You could do something much cooler like this:

filename="filename"
extension="txt"
for i in {1..20}; do
    eval "filename${i}=${filename}${i}.${extension}"
    touch filename${i}
    echo "this rox" > filename${i}
done

This code will create 20 files and dynamically set 20 variables. Of course you could use an array, but I'm just showing you the feature :). Note that you can use the variables $filename1, $filename2, $filename3... because they were created with evaluate command. In this case I'm just creating files, but you could use to create dynamically arguments to the commands, and then execute in background.

yauzl is a robust library for unzipping. Design principles:

• Follow the spec. Don't scan for local file headers. Read the central directory for file metadata.
• Don't block the JavaScript thread. Use and provide async APIs.
• Keep memory usage under control. Don't attempt to buffer entire files in RAM at once.
• Never crash (if used properly). Don't let malformed zip files bring down client applications who are trying to catch errors.
• Catch unsafe filenames entries. A zip file entry throws an error if its file name starts with "/" or /[A-Za-z]:// or if it contains ".." path segments or "\" (per the spec).

Currently has 97% test coverage.

If you add a $scope.$apply(); right after $scope.pluginsDisplayed.splice(index,1); then it works.

I am not sure why this is happening, but basically when AngularJS doesn't know that the $scope has changed, it requires to call $apply manually. I am also new to AngularJS so cannot explain this better. I need too look more into it.

I found this awesome article that explains it quite properly. Note: I think it might be better to use ng-click (docs) rather than binding to "mousedown". I wrote a simple app here (http://avinash.me/losh, source http://github.com/hardfire/losh) based on AngularJS. It is not very clean, but it might be of help.

do you mean a method?

$('div.foo').attr('id', 'foo123');

Just be careful that you don't set multiple elements to the same ID.

The answer given by Nico O is correct. However this doesn't get the desired result on Internet Explorer 10 to 11 and Firefox.

For IE, I found that changing

.flex > div
{
   flex: 1 0 50%;
}

to

.flex > div
{
   flex: 1 0 45%;
}

seems to do the trick. Don't ask me why, I haven't gone any further into this but it might have something to do with how IE renders the border-box or something.

In the case of Firefox I solved it by adding

display: inline-block;

to the items.

This scope https://www.googleapis.com/auth/userinfo.profile has been deprecated now. Please look at https://developers.google.com/+/api/auth-migration#timetable.

New scope you will be using to get profile info is: profile or https://www.googleapis.com/auth/plus.login

and the endpoint is - https://www.googleapis.com/plus/v1/people/{userId} - userId can be just 'me' for currently logged in user.

The problem is caused by the fact that the Model's toArray() method ignores any accessors which do not directly relate to a column in the underlying table.

As Taylor Otwell mentioned here, "This is intentional and for performance reasons." However there is an easy way to achieve this:

class EventSession extends Eloquent {

    protected $table = 'sessions';
    protected $appends = array('availability');

    public function getAvailabilityAttribute()
    {
        return $this->calculateAvailability();  
    }
}

Any attributes listed in the $appends property will automatically be included in the array or JSON form of the model, provided that you've added the appropriate accessor.

Old answer (for Laravel versions < 4.08):

The best solution that I've found is to override the toArray() method and either explicity set the attribute:

class Book extends Eloquent {

    protected $table = 'books';

    public function toArray()
    {
        $array = parent::toArray();
        $array['upper'] = $this->upper;
        return $array;
    }

    public function getUpperAttribute()
    {
        return strtoupper($this->title);    
    }

}

or, if you have lots of custom accessors, loop through them all and apply them:

class Book extends Eloquent {

    protected $table = 'books';

    public function toArray()
    {
        $array = parent::toArray();
        foreach ($this->getMutatedAttributes() as $key)
        {
            if ( ! array_key_exists($key, $array)) {
                $array[$key] = $this->{$key};   
            }
        }
        return $array;
    }

    public function getUpperAttribute()
    {
        return strtoupper($this->title);    
    }

}

If you want to re-use the connection then you must consume content stream completely after every use as follows :

EntityUtils.consume(response.getEntity())

Note : you need to consume the content stream even if the status code is not 200. Not doing so will raise the following on next use :

Exception in thread "main" java.lang.IllegalStateException: Invalid use of SingleClientConnManager: connection still allocated. Make sure to release the connection before allocating another one.

If it's a one time use, then simply closing the connection will release all the resources associated with it.

Using CLI:

Server version:

$ postgres -V  # Or --version.  Use "locate bin/postgres" if not found.
postgres (PostgreSQL) 9.6.1
$ postgres -V | awk '{print $NF}'  # Last column is version.
9.6.1
$ postgres -V | egrep -o '[0-9]{1,}\.[0-9]{1,}'  # Major.Minor version
9.6

If having more than one installation of PostgreSQL, or if getting the "postgres: command not found" error:

$ locate bin/postgres | xargs -i xargs -t '{}' -V  # xargs is intentionally twice.
/usr/pgsql-9.3/bin/postgres -V 
postgres (PostgreSQL) 9.3.5
/usr/pgsql-9.6/bin/postgres -V 
postgres (PostgreSQL) 9.6.1

If locate doesn't help, try find:

$ sudo find / -wholename '*/bin/postgres' 2>&- | xargs -i xargs -t '{}' -V  # xargs is intentionally twice.
/usr/pgsql-9.6/bin/postgres -V 
postgres (PostgreSQL) 9.6.1

Although postmaster can also be used instead of postgres, using postgres is preferable because postmaster is a deprecated alias of postgres.

Client version:

As relevant, login as postgres.

$ psql -V  # Or --version
psql (PostgreSQL) 9.6.1

If having more than one installation of PostgreSQL:

$ locate bin/psql | xargs -i xargs -t '{}' -V  # xargs is intentionally twice.
/usr/bin/psql -V 
psql (PostgreSQL) 9.3.5
/usr/pgsql-9.2/bin/psql -V 
psql (PostgreSQL) 9.2.9
/usr/pgsql-9.3/bin/psql -V 
psql (PostgreSQL) 9.3.5

Using SQL:

Server version:

=> SELECT version();
                                                   version                                                    
--------------------------------------------------------------------------------------------------------------
 PostgreSQL 9.2.9 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.4.7 20120313 (Red Hat 4.4.7-4), 64-bit

=> SHOW server_version;
 server_version 
----------------
 9.2.9

=> SHOW server_version_num;
 server_version_num 
--------------------
 90209

If more curious, try => SHOW all;.

Client version:

For what it's worth, a shell command can be executed within psql to show the client version of the psql executable in the path. Note that the running psql can potentially be different from the one in the path.

=> \! psql -V
psql (PostgreSQL) 9.2.9

Composition

final class Car {

  private final Engine engine;

  Car(EngineSpecs specs) {
    engine = new Engine(specs);
  }

  void move() {
    engine.work();
  }
}

Aggregation

final class Car {

  private Engine engine;

  void setEngine(Engine engine) {
    this.engine = engine;
  }

  void move() {
    if (engine != null)
      engine.work();
  }
}

In the case of composition, the Engine is completely encapsulated by the Car. There is no way for the outside world to get a reference to the Engine. The Engine lives and dies with the car. With aggregation, the Car also performs its functions through an Engine, but the Engine is not always an internal part of the Car. Engines may be swapped, or even completely removed. Not only that, but the outside world can still have a reference to the Engine, and tinker with it regardless of whether it's in the Car.

From stack trace:

HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.

The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.

Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.

otherwise, your maximum connections 'at a time' requirement is higher than 20 !

You can attach a handler which would call as many others as you like:

<a href="#blah" id="myLink"/>

<script type="text/javascript">

function myOtherFunction() {
//do stuff...
}

document.getElementById( 'myLink' ).onclick = function() {
   //do stuff...
   myOtherFunction();
};

</script>

In case you are uploading an sql file on cpanel, then try and replace root with your cpanel username in your sql file.

in the case above you could write

CREATE DEFINER = control_panel_username@localhost FUNCTION fnc_calcWalkedDistance

then upload the file. Hope it helps

Remove a block of code from multiple files

To expand on @Markus Olsson's answer, I needed to remove a block of code from multiple files. I had problems with Swedish characters in a core project, so I needed to install System.Text.CodePagesEncodingProvider nuget package and use System.Text.Encoding.GetEncoding(1252) instead of System.Text.Encoding.UTF8.

    public static void Main(string[] args)
    {
        try
        {
            var dir = @"C:\Test";
            //Get all html and htm files
            var files = DirSearch(dir);
            foreach (var file in files)
            {
                RmCode(file);
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
            throw;
        }

    }

    private static void RmCode(string file)
    {
        string tempFile = Path.GetTempFileName();

        using (var sr = new StreamReader(file, Encoding.UTF8))
        using (var sw = new StreamWriter(new FileStream(tempFile, FileMode.Open, FileAccess.ReadWrite), Encoding.UTF8))
        {
            string line;

            var startOfBadCode = "<div>";
            var endOfBadCode = "</div>";
            var deleteLine = false;

            while ((line = sr.ReadLine()) != null)
            {
                if (line.Contains(startOfBadCode))
                {
                    deleteLine = true;
                }
                if (!deleteLine)
                {
                    sw.WriteLine(line);
                }

                if (line.Contains(endOfBadCode))
                {
                    deleteLine = false;
                }
            }
        }

        File.Delete(file);
        File.Move(tempFile, file);
    }

    private static List<String> DirSearch(string sDir)
    {
        List<String> files = new List<String>();
        try
        {
            foreach (string f in Directory.GetFiles(sDir))
            {
                files.Add(f);
            }
            foreach (string d in Directory.GetDirectories(sDir))
            {
                files.AddRange(DirSearch(d));
            }
        }
        catch (System.Exception excpt)
        {
            Console.WriteLine(excpt.Message);
        }

        return files.Where(s => s.EndsWith(".htm") || s.EndsWith(".html")).ToList();
    }

If anyone would be missing his APK and couldn't find it in the locations stated in other answers (I found this question, since I couldn't find it either) it might just be in this folder (mine was)

<project folder>/target/classes/<appname>.apk 

I also had a there this file:

<appname>.unaligned.apk

I am not perfectly sure, whether the apk is actually the full-blown apk, which should be generated, but I tried it on various devices (not only the target device, but also those which were supporting only the minimum SDK) and it worked.

Hope this will help someone.

I use Xcode 7 and Swift 2. Last, I had made:

class ViewController: UIViewController{ var time: NSTimer //error this here }

Then I fix: class ViewController: UIViewController {

var time: NSTimer!
override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

override func viewWillAppear(animated: Bool) {
    //self.movetoHome()
    time = NSTimer.scheduledTimerWithTimeInterval(5.0, target: self, selector: #selector(ViewController.movetoHome), userInfo: nil, repeats: false)
    //performSegueWithIdentifier("MoveToHome", sender: self)
    //presentViewController(<#T##viewControllerToPresent: UIViewController##UIViewController#>, animated: <#T##Bool#>, completion: <#T##(() -> Void)?##(() -> Void)?##() -> Void#>)
}

func movetoHome(){
    performSegueWithIdentifier("MoveToHome", sender: self)
}

}

Here's a working solution that creates admin-user user with a password, additional database (test-database), and test-user in that database.

Dockerfile:

FROM mongo:4.0.3

ENV MONGO_INITDB_ROOT_USERNAME admin-user
ENV MONGO_INITDB_ROOT_PASSWORD admin-password
ENV MONGO_INITDB_DATABASE admin

ADD mongo-init.js /docker-entrypoint-initdb.d/

mongo-init.js:

db.auth('admin-user', 'admin-password')

db = db.getSiblingDB('test-database')

db.createUser({
  user: 'test-user',
  pwd: 'test-password',
  roles: [
    {
      role: 'root',
      db: 'test-database',
    },
  ],
});

The tricky part was to understand that *.js files were run unauthenticated. The solution authenticates the script as the admin-user in the admin database. MONGO_INITDB_DATABASE admin is essential, otherwise the script would be executed against the test db. Check the source code of docker-entrypoint.sh.
