After

apply plugin: 'com.android.application'

You should add this:

  repositories {
        mavenCentral()
        maven {
            url "https://repository-achartengine.forge.cloudbees.com/snapshot/"
        }
    }

@Benjamin explained the reason.

If you have a maven with authentication you can use:

repositories {
            mavenCentral()
            maven {
               credentials {
                   username xxx
                   password xxx
               }
               url    'http://mymaven/xxxx/repositories/releases/'
            }
}

It is important the order.

As explained in this forum post, 1 and 2 are related. If you set hibernate.current_session_context_class to thread and then implement something like a servlet filter that opens the session - then you can access that session anywhere else by using the SessionFactory.getCurrentSession().

SessionFactory.openSession() always opens a new session that you have to close once you are done with the operations. SessionFactory.getCurrentSession() returns a session bound to a context - you don't need to close this.

If you are using Spring or EJBs to manage transactions you can configure them to open / close sessions along with the transactions.

You should never use one session per web app - session is not a thread safe object - cannot be shared by multiple threads. You should always use "one session per request" or "one session per transaction"

See my answer at https://stackoverflow.com/a/18471979/193494 for a comprehensive overview of possible solutions:

1. using multiple backgrounds with a linear gradient,
2. multiple backgrounds with a generated PNG, or
3. styling an :after pseudoelement to act as a secondary background layer.

Rob's answer would be the most vendor-agnostic, but if you're using MySQL the safer and correct choise would be the built-in LAST_INSERT_ID() function.

A quick and dirty way is to use Thread.currentThread().setName(myName); in the run() method.

The answer should be Jain. You can not select an element via pseudo-selector, but you can add a new rule to your stylesheet with insertRule.

I made something that should work for you:

var addRule = function(sheet, selector, styles) {
    if (sheet.insertRule) return sheet.insertRule(selector + " {" + styles + "}", sheet.cssRules.length);
    if (sheet.addRule) return sheet.addRule(selector, styles);
};

addRule(document.styleSheets[0], "body:before", "content: 'foo'");

To be super-cool (and to answer the question really) I rolled it out again and wrapped this in a jQuery-plugin (however, jquery is still not required!):

A simple explanation of the difference between json and jsonb (original image by PostgresProfessional):

SELECT '{"c":0,   "a":2,"a":1}'::json, '{"c":0,   "a":2,"a":1}'::jsonb;

          json          |        jsonb 
------------------------+--------------------- 
 {"c":0,   "a":2,"a":1} | {"a": 1, "c": 0} 
(1 row)

• json: textual storage «as is»
• jsonb: no whitespaces
• jsonb: no duplicate keys, last key win
• jsonb: keys are sorted

More in speech video and slide show presentation by jsonb developers. Also they introduced JsQuery, pg.extension provides powerful jsonb query language

len(queue) should give you the result, 3 in this case.

Specifically, len(object) function will call object.__len__ method [reference link]. And the object in this case is deque, which implements __len__ method (you can see it by dir(deque)).

queue= deque([])   #is this length 0 queue?

Yes it will be 0 for empty deque.

Update

The solution below has a "SEO friendlier" version:

function hyphenize($string) {
    $dict = array(
        "I'm"      => "I am",
        "thier"    => "their",
        // Add your own replacements here
    );
    return strtolower(
        preg_replace(
          array( '#[\\s-]+#', '#[^A-Za-z0-9. -]+#' ),
          array( '-', '' ),
          // the full cleanString() can be downloaded from http://www.unexpectedit.com/php/php-clean-string-of-utf8-chars-convert-to-similar-ascii-char
          cleanString(
              str_replace( // preg_replace can be used to support more complicated replacements
                  array_keys($dict),
                  array_values($dict),
                  urldecode($string)
              )
          )
        )
    );
}

function cleanString($text) {
    $utf8 = array(
        '/[áàâãªä]/u'   =>   'a',
        '/[ÁÀÂÃÄ]/u'    =>   'A',
        '/[ÍÌÎÏ]/u'     =>   'I',
        '/[íìîï]/u'     =>   'i',
        '/[éèêë]/u'     =>   'e',
        '/[ÉÈÊË]/u'     =>   'E',
        '/[óòôõºö]/u'   =>   'o',
        '/[ÓÒÔÕÖ]/u'    =>   'O',
        '/[úùûü]/u'     =>   'u',
        '/[ÚÙÛÜ]/u'     =>   'U',
        '/ç/'           =>   'c',
        '/Ç/'           =>   'C',
        '/ñ/'           =>   'n',
        '/Ñ/'           =>   'N',
        '/–/'           =>   '-', // UTF-8 hyphen to "normal" hyphen
        '/[’‘‹›‚]/u'    =>   ' ', // Literally a single quote
        '/[“”«»„]/u'    =>   ' ', // Double quote
        '/ /'           =>   ' ', // nonbreaking space (equiv. to 0x160)
    );
    return preg_replace(array_keys($utf8), array_values($utf8), $text);
}

The rationale for the above functions (which I find way inefficient - the one below is better) is that a service that shall not be named apparently ran spelling checks and keyword recognition on the URLs.

After losing a long time on a customer's paranoias, I found out they were not imagining things after all -- their SEO experts [I am definitely not one] reported that, say, converting "Viaggi Economy Perù" to viaggi-economy-peru "behaved better" than viaggi-economy-per (the previous "cleaning" removed UTF8 characters; Bogotà became bogot, Medellìn became medelln and so on).

There were also some common misspellings that seemed to influence the results, and the only explanation that made sense to me is that our URL were being unpacked, the words singled out, and used to drive God knows what ranking algorithms. And those algorithms apparently had been fed with UTF8-cleaned strings, so that "Perù" became "Peru" instead of "Per". "Per" did not match and sort of took it in the neck.

In order to both keep UTF8 characters and replace some misspellings, the faster function below became the more accurate (?) function above. $dict needs to be hand tailored, of course.

Previous answer

A simple approach:

// Remove all characters except A-Z, a-z, 0-9, dots, hyphens and spaces
// Note that the hyphen must go last not to be confused with a range (A-Z)
// and the dot, NOT being special (I know. My life was a lie), is NOT escaped

$str = preg_replace('/[^A-Za-z0-9. -]/', '', $str);

// Replace sequences of spaces with hyphen
$str = preg_replace('/  */', '-', $str);

// The above means "a space, followed by a space repeated zero or more times"
// (should be equivalent to / +/)

// You may also want to try this alternative:
$str = preg_replace('/\\s+/', '-', $str);

// where \s+ means "zero or more whitespaces" (a space is not necessarily the
// same as a whitespace) just to be sure and include everything

Note that you might have to first urldecode() the URL, since %20 and + both are actually spaces - I mean, if you have "Never%20gonna%20give%20you%20up" you want it to become Never-gonna-give-you-up, not Never20gonna20give20you20up . You might not need it, but I thought I'd mention the possibility.

So the finished function along with test cases:

function hyphenize($string) {
    return 
    ## strtolower(
          preg_replace(
            array('#[\\s-]+#', '#[^A-Za-z0-9. -]+#'),
            array('-', ''),
        ##     cleanString(
              urldecode($string)
        ##     )
        )
    ## )
    ;
}

print implode("\n", array_map(
    function($s) {
            return $s . ' becomes ' . hyphenize($s);
    },
    array(
    'Never%20gonna%20give%20you%20up',
    "I'm not the man I was",
    "'Légeresse', dit sa majesté",
    )));


Never%20gonna%20give%20you%20up    becomes  never-gonna-give-you-up
I'm not the man I was              becomes  im-not-the-man-I-was
'Légeresse', dit sa majesté        becomes  legeresse-dit-sa-majeste

To handle UTF-8 I used a cleanString implementation found online (link broken since, but a stripped down copy with all the not-too-esoteric UTF8 characters is at the beginning of the answer; it's also easy to add more characters to it if you need) that converts UTF8 characters to normal characters, thus preserving the word "look" as much as possible. It could be simplified and wrapped inside the function here for performance.

The function above also implements converting to lowercase - but that's a taste. The code to do so has been commented out.

@media screen and (max-width : 320px)
{
  body or yourdiv element
  {
    font:<size>px/em/rm;
  }
}
@media screen and (max-width : 1204px)
{
  body or yourdiv element
  {
    font:<size>px/em/rm;
  }
}

You can give it manually according to screen size of screen.Just have a look of different screen size and add manually the font size.

Use:

ImageView image = (ImageView) findViewById(R.id.image);
image.setAlpha(150); // Value: [0-255]. Where 0 is fully transparent
                     // and 255 is fully opaque. Set the value according
                     // to your choice, and you can also use seekbar to
                     // maintain the transparency.

I used Ctrl + F5 keyboard combination. By doing so, instead of reading from cache, I wanted to get a new response. The solution is to do hard refresh the page.

On MDN Web Docs:

"The HTTP 304 Not Modified client redirection response code indicates that there is no need to retransmit the requested resources. It is an implicit redirection to a cached resource."

This is the code to update the file but not to install This program is made through dos for copying files to the latest date and run your program automatically. may help you

open notepad and save file below with ext .bat

xcopy \\IP address\folder_share_name\*.* /s /y /d /q  
start "label" /b "youraplicationname.exe"

You may use the typescript getter method for this scenario. Like this

public get height() {
  return window.innerHeight;
}

public get width() {
  return window.innerWidth;
}

And use that in template like this:

<section [ngClass]="{ 'desktop-view': width >= 768, 'mobile-view': width < 768 
}"></section>

Print the value

console.log(this.height, this.width);

You won't need any event handler to check for resizing of window, this method will check for size every time automatically.

I could do that following the steps:

1. Create a folder __mocks__/ (as pointed by @Januartha comment)
2. Implement an axios.js mock file
3. Use my implemented module on test

The mock will happen automatically

Example of the mock module:

module.exports = {
    get: jest.fn((url) => {
        if (url === '/something') {
            return Promise.resolve({
                data: 'data'
            });
        }
    }),
    post: jest.fn((url) => {
        if (url === '/something') {
            return Promise.resolve({
                data: 'data'
            });
        }
        if (url === '/something2') {
            return Promise.resolve({
                data: 'data2'
            });
        }
    }),
    create: jest.fn(function () {
        return this;
    })
};

You can just use the global object.

var X = ['a', 'b', 'c'];
global.x = X;

console.log(x);
//['a', 'b', 'c']

You can use a for-loop to address a field with $i:

ls -l | awk '{for(i=3 ; i<8 ; i++) {printf("%s\t", $i)} print ""}'

The Javadoc for String reveals that String.split() is what you're looking for in regard to explode.

Java does not include a "implode" of "join" equivalent. Rather than including a giant external dependency for a simple function as the other answers suggest, you may just want to write a couple lines of code. There's a number of ways to accomplish that; using a StringBuilder is one:

String foo = "This,that,other";
String[] split = foo.split(",");
StringBuilder sb = new StringBuilder();
for (int i = 0; i < split.length; i++) {
    sb.append(split[i]);
    if (i != split.length - 1) {
        sb.append(" ");
    }
}
String joined = sb.toString();

Yes, it can throw an exception and you can declare that in the signature of the constructor too as shown in the example below:

public class ConstructorTest
{
    public ConstructorTest() throws InterruptedException
    {
        System.out.println("Preparing object....");
        Thread.sleep(1000);
        System.out.println("Object ready");
    }

    public static void main(String ... args)
    {
        try
        {
            ConstructorTest test = new ConstructorTest();
        }
        catch (InterruptedException e)
        {
            System.out.println("Got interrupted...");
        }
    }
}

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

Try this.

if(is_array($value) || is_object($value)){
    foreach($value as $item){
     //somecode
    }
}

The main difference is that Collections.emptyList() returns an immutable list, i.e., a list to which you cannot add elements. (Same applies to the List.of() introduced in Java 9.)

In the rare cases where you do want to modify the returned list, Collections.emptyList() and List.of() are thus not a good choices.

I'd say that returning an immutable list is perfectly fine (and even the preferred way) as long as the contract (documentation) does not explicitly state differently.

In addition, emptyList() might not create a new object with each call.

Implementations of this method need not create a separate List object for each call. Using this method is likely to have comparable cost to using the like-named field. (Unlike this method, the field does not provide type safety.)

The implementation of emptyList looks as follows:

public static final <T> List<T> emptyList() {
    return (List<T>) EMPTY_LIST;
}

So if your method (which returns an empty list) is called very often, this approach may even give you slightly better performance both CPU and memory wise.

In cryptography there are two types of algorithms used:

Symmetric algorithms

A single key is used to encrypt data. When encrypted with the key, the data can be decrypted using the same key. If, for example, Mary encrypts a message using the key "my-secret" and sends it to John, he will be able to decrypt the message correctly with the same key "my-secret".

Asymmetric algorithms

Two keys are used to encrypt and decrypt messages. While one key(public) is used to encrypt the message, the other key(private) can only be used to decrypt it. So, John can generate both public and private keys, then send only the public key to Mary to encrypt her message. The message can only be decrypted using the private key.

HS256 and RS256 Scenario

These algorithms are NOT used to encrypt/decryt data. Rather they are used to verify the origin or the authenticity of the data. When Mary needs to send an open message to Jhon and he needs to verify that the message is surely from Mary, HS256 or RS256 can be used.

HS256 can create a signature for a given sample of data using a single key. When the message is transmitted along with the signature, the receiving party can use the same key to verify that the signature matches the message.

RS256 uses pair of keys to do the same. A signature can only be generated using the private key. And the public key has to be used to verify the signature. In this scenario, even if Jack finds the public key, he cannot create a spoof message with a signature to impersonate Mary.

I saw some errors, which I've fixed below.

Normally set does not keep the order, such as HashSet in order to quickly find a emelent, but you can try LinkedHashSet it will keep the order which you put in.

Check your random_page_cost

This problem typically happens when the estimated cost of an index scan is too high and doesn't correctly reflect reality. You may need to lower the random_page_cost configuration parameter to fix this. From the Postgres documentation:

Reducing this value [...] will cause the system to prefer index scans; raising it will make index scans look relatively more expensive.

You can do a quick test whether this will actually make Postgres use the index:

EXPLAIN <query>;              # Uses sequential scan
SET random_page_cost = 1;
EXPLAIN <query>;              # May use index scan now

You can restore the default value with SET random_page_cost = DEFAULT; again.

Background

Index scans require non-sequential disk page fetches. Postgres uses random_page_cost to estimate the cost of such non-sequential fetches in relation to sequential fetches. The default value is 4.0, thus assuming an average cost factor of 4 compared to sequential fetches (taking caching effects into account).

The problem however is that this default value is unsuitable in the following important real-life scenarios:

1) Solid-state drives

As per the documentation:

Storage that has a low random read cost relative to sequential, e.g. solid-state drives, might be better modeled with a lower value for random_page_cost, e.g., 1.1.

This slide from a speak at PostgresConf 2018 also says that random_page_cost should be set to something between 1.0 and 2.0 for solid-state drives.

2) Cached data

If the required index data is already cached in RAM, an index scan will always be significantly faster than a sequential scan. The documentation says:

If your data is likely to be completely in cache, [...] decreasing random_page_cost can be appropriate.

The problem is that you of course can't easily know whether the relevant data is already cached. However, if a specific index is frequently used, and if the system has sufficient RAM, then data is likely to be cached eventually, and random_page_cost should be set to a lower value. You'll have to experiment with different values and see what works for you.

You might also want to use the pg_prewarm extension for explicit data caching.

Just to add to the answers, I think the specific reason in this case, in addition to the misplaced no-repeat, is the space between url and (:

background-image: url ('/image/btn.png') no-repeat; /* Won't work */
background-image: url('/image/btn.png'); /* Should work */

Try to split the characters into multiple chunks like the query below and try:

Insert into table (clob_column) values ( to_clob( 'chunk 1' ) || to_clob( 'chunk 2' ) );

It worked for me.

MP4 is just a container - the video and audio stream inside it will both be encoded in different formats.

Android natively only supports certain types of formats. This is the list here.

Make sure the video and audio encoding type is supported. Just because it says "mp4" doesn't automatically mean it should be playable.

    print(car)
    for key,value in info.items():

You can use this func:

func randomString(length int) string {
    b := make([]byte, length)
    rand.Read(b)
    return fmt.Sprintf("%x", b)[:length]
}

There are some limitations with close() that can be avoided if one uses shutdown() instead.

close() will terminate both directions on a TCP connection. Sometimes you want to tell the other endpoint that you are finished with sending data, but still want to receive data.

close() decrements the descriptors reference count (maintained in file table entry and counts number of descriptors currently open that are referring to a file/socket) and does not close the socket/file if the descriptor is not 0. This means that if you are forking, the cleanup happens only after reference count drops to 0. With shutdown() one can initiate normal TCP close sequence ignoring the reference count.

Parameters are as follows:

int shutdown(int s, int how); // s is socket descriptor

int how can be:

SHUT_RD or 0 Further receives are disallowed

SHUT_WR or 1 Further sends are disallowed

SHUT_RDWR or 2 Further sends and receives are disallowed

For compression, I would use a library (7-Zip is good like Michal suggests).

If you install 7-Zip, the installed directory will contain 7z.exe which is a console application.
You can invoke it directly and use any compression option you want.

If you wish to engage with the DLL, that should also be possible.
7-Zip is freeware and open source.

The default (when created with the designer) is:

label.ForeColor = SystemColors.ControlText;

This should respect the system color settings (e.g. these "high contrast" schemes for visual impaired).

In Windows 10 using node v6.11.2 and npm v3.10.10, in order to execute directly in any folder:

> node-sass [options] <input.scss> [output.css]

I only followed the instructions in node-sass Github:

1. Add node-gyp prerequisites by running as Admin in a Powershell (it takes a while):

   > npm install --global --production windows-build-tools
   

2. In a normal command-line shell (Win+R+cmd+Enter) run:

   > npm install -g node-gyp
   > npm install -g node-sass
   

   The -g places these packages under %userprofile%\AppData\Roaming\npm\node_modules. You may check that npm\node_modules\node-sass\bin\node-sass now exists.

3. Check if your local account (not the System) PATH environment variable contains:

   %userprofile%\AppData\Roaming\npm
   

   If this path is not present, npm and node may still run, but the modules bin files will not!

Close the previous shell and reopen a new one and run either > node-gyp or > node-sass.

Note:

• The windows-build-tools may not be necessary (if no compiling is done? I'd like to read if someone made it without installing these tools), but it did add to the admin account the GYP_MSVS_VERSION environment variable with 2015 as a value.
• I am also able to run directly other modules with bin files, such as > uglifyjs main.js main.min.js and > mocha

Look up the AbortException class for Jenkins. You should be able to use the methods to get back simple messages or stack traces. In a simple case, when making a call in a script block (as others have indicated), you can call getMessage() to get the string to echo to the user. Example:

script {
        try {
            sh "sudo docker rmi frontend-test"
        } catch (err) {
            echo err.getMessage()
            echo "Error detected, but we will continue."
        }
        ...continue with other code...
}

They are synonyms, no difference at all.Decimal and Numeric data types are numeric data types with fixed precision and scale.

-- Initialize a variable, give it a data type and an initial value

declare @myvar as decimal(18,8) or numeric(18,8)----- 9 bytes needed

-- Increse that the vaue by 1

set @myvar = 123456.7

--Retrieve that value

select @myvar as myVariable

In my case this error occurred with dot net core and Microsoft.Data.SqlClient. The solution was to add ;TrustServerCertificate=true to the end of the connection string.

For people who are still getting error despite of passing absolute path, should check that if file has a valid name. For me I was trying to create a file with '/' in the file name. As soon as I removed '/', I was able to create the file.

It turns out the answer was ridiculously simple, but mystifying as to why it was necessary.

In the IIS Manager on the server, I set the application pool for my web application to not allow 32-bit assemblies.

It seems it assumes, on a 64-bit system, that you must want the 32 bit assembly. Bizarre.

After hours of research, I finally found a solution to take a screenshot of an element, even if the origin-clean FLAG is set (to prevent XSS), that´s why you can even capture for example Google Maps (in my case). I wrote a universal function to get a screenshot. The only thing you need in addition is the html2canvas library (https://html2canvas.hertzen.com/).

Example:

getScreenshotOfElement($("div#toBeCaptured").get(0), 0, 0, 100, 100, function(data) {
    // in the data variable there is the base64 image
    // exmaple for displaying the image in an <img>
    $("img#captured").attr("src", "data:image/png;base64,"+data);
});

Keep in mind console.log() and alert() won´t generate output if the size of the image is great.

Function:

function getScreenshotOfElement(element, posX, posY, width, height, callback) {
    html2canvas(element, {
        onrendered: function (canvas) {
            var context = canvas.getContext('2d');
            var imageData = context.getImageData(posX, posY, width, height).data;
            var outputCanvas = document.createElement('canvas');
            var outputContext = outputCanvas.getContext('2d');
            outputCanvas.width = width;
            outputCanvas.height = height;

            var idata = outputContext.createImageData(width, height);
            idata.data.set(imageData);
            outputContext.putImageData(idata, 0, 0);
            callback(outputCanvas.toDataURL().replace("data:image/png;base64,", ""));
        },
        width: width,
        height: height,
        useCORS: true,
        taintTest: false,
        allowTaint: false
    });
}

i wrote this sp to create automatically the schema with all things, pk, fk, partitions, constraints... I wrote it to run in same sp.

Policykit is a system daemon and policykit authentication agent is used to verify identity of the user before executing actions. The messages logged in /var/log/secure show that an authentication agent is registered when user logs in and it gets unregistered when user logs out. These messages are harmless and can be safely ignored.

It happens because the component is rendered before the async data arrived, you should control before to render.

I resolved it in this way:

render() {
    let partners = this.props && this.props.partners.length > 0 ?
        this.props.partners.map(p=>
            <li className = "partners" key={p.id}>
                <img src={p.img} alt={p.name}/> {p.name} </li>
        ) : <span></span>;

    return (
        <div>
            <ul>{partners}</ul>
        </div>
    );
}

• Map can not resolve when the property is null/undefined, so I did a control first

this.props && this.props.partners.length > 0 ?

self.materials is a dict and by default you are iterating over just the keys (which are strings).

Since self.materials has more than two keys*, they can't be unpacked into the tuple "k, m", hence the ValueError exception is raised.

In Python 2.x, to iterate over the keys and the values (the tuple "k, m"), we use self.materials.iteritems().

However, since you're throwing the key away anyway, you may as well simply iterate over the dictionary's values:

for m in self.materials.itervalues():

In Python 3.x, prefer dict.values() (which returns a dictionary view object):

for m in self.materials.values():

I had the same issue when tried to open the file using Plot->Data filename... option provided in the version for Windows 7 (by the way, it worked fine on another computer with the same version of the OP system).

Then I tried to change directory and save the .plt file, but it didn't work either. Finally, I tried to tape manually as it was showed for Linux earlier in this queue of posts:

gnuplot > plot "./datafile.dat"

and it worked!

Something like this:

var div = document.getElementById("result");_x000D_
_x000D_
var str = "{'a':1}";_x000D_
  str = str.replace(/\'/g, '"');_x000D_
  var parsed = JSON.parse(str);_x000D_
  console.log(parsed);_x000D_
  div.innerText = parsed.a;

<div id="result"></div>

Super Duper Old I know but I would add my piece on using Linq and continuation lambdas on methods with using C# 7. I try to use named tuples as replacements for DTOs and anonymous projections when reused in a class. Yes for mocking and testing you still need classes but doing things inline and passing around in a class is nice to have this newer option IMHO. You can instantiate them from

1. Direct Instantiation

var items = new List<(int Id, string Name)> { (1, "Me"), (2, "You")};

2. Off of an existing collection, and now you can return well typed tuples similar to how anonymous projections used to be done.

public class Hold
{
    public int Id { get; set; }
    public string Name { get; set; }
}

//In some method or main console app:
var holds = new List<Hold> { new Hold { Id = 1, Name = "Me" }, new Hold { Id = 2, Name = "You" } };
var anonymousProjections = holds.Select(x => new { SomeNewId = x.Id, SomeNewName = x.Name });
var namedTuples = holds.Select(x => (TupleId: x.Id, TupleName: x.Name));

3. Reuse the tuples later with grouping methods or use a method to construct them inline in other logic:

//Assuming holder class above making 'holds' object
public (int Id, string Name) ReturnNamedTuple(int id, string name) => (id, name);
public static List<(int Id, string Name)> ReturnNamedTuplesFromHolder(List<Hold> holds) => holds.Select(x => (x.Id, x.Name)).ToList();
public static void DoSomethingWithNamedTuplesInput(List<(int id, string name)> inputs) => inputs.ForEach(x => Console.WriteLine($"Doing work with {x.id} for {x.name}"));

var namedTuples2 = holds.Select(x => ReturnNamedTuple(x.Id, x.Name));
var namedTuples3 = ReturnNamedTuplesFromHolder(holds);
DoSomethingWithNamedTuplesInput(namedTuples.ToList());

There are several

The "obvious" way (for most people)

theBoolean = !theBoolean;

The "shortest" way (most of the time)

theBoolean ^= true;

The "most visual" way (most uncertainly)

theBoolean = theBoolean ? false : true;

Extra: Toggle and use in a method call

theMethod( theBoolean ^= true );

Since the assignment operator always returns what has been assigned, this will toggle the value via the bitwise operator, and then return the newly assigned value to be used in the method call.

You can further simplify the accepted answer. Instead of typing out the enums as strings in xaml and doing more work in your converter than needed, you can explicitly pass in the enum value instead of a string representation, and as CrimsonX commented, errors get thrown at compile time rather than runtime:

ConverterParameter={x:Static local:YourEnumType.Enum1}

<StackPanel>
    <StackPanel.Resources>          
        <local:ComparisonConverter x:Key="ComparisonConverter" />          
    </StackPanel.Resources>
    <RadioButton IsChecked="{Binding Path=YourEnumProperty, Converter={StaticResource ComparisonConverter}, ConverterParameter={x:Static local:YourEnumType.Enum1}}" />
    <RadioButton IsChecked="{Binding Path=YourEnumProperty, Converter={StaticResource ComparisonConverter}, ConverterParameter={x:Static local:YourEnumType.Enum2}}" />
</StackPanel>

Then simplify the converter:

public class ComparisonConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return value?.Equals(parameter);
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return value?.Equals(true) == true ? parameter : Binding.DoNothing;
    }
}

Edit (Dec 16 '10):

Note - Multiple groups of RadioButtons in same container (Feb 17 '11):

Edit (Apr 5 '11):

Note - Enum type nested in a class (Apr 28 '11):

ConverterParameter={x:Static local:YourClass+YourNestedEnumType.Enum1}

Due to this Microsoft Connect Issue, however, the designer in VS2010 will no longer load stating "Type 'local:YourClass+YourNestedEnumType' was not found.", but the project does compile and run successfully. Of course, you can avoid this issue if you are able to move your enum type to the namespace directly.

Edit (Jan 27 '12):

public class EnumToBooleanConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return ((Enum)value).HasFlag((Enum)parameter);
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        return value.Equals(true) ? parameter : Binding.DoNothing;
    }
}

Edit (May 7 '15):

    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        if (value == null) {
            return false; // or return parameter.Equals(YourEnumType.SomeDefaultValue);
        }
        return value.Equals(parameter);
    }

I was looking long and hard for a solution to this problem and the best I found was a root FTP server on the phone that you connect to on Windows with an FTP client like FileZilla, on the same WiFi network of course.

The root FTP server app I ended up using is FTP Droid. I tried a lot of other FTP apps with bigger download numbers but none of them worked for me for whatever reason. So install this app and set a user with home as / or wherever you want.

Then make note of the phone IP and connect with FileZilla and you should have access to the root of the phone. The biggest benefit I found is I can download entire folders and FTP will just queue it up and take care of it. So I downloaded all of my /data/data/ folder when I was looking for an app and could search on my PC. Very handy.

I checked for similar answer, but those given here don't fit my needs. I find something that, from my point of view, is what you're looking for. The only possible black point is a security matter (or maybe not) since I don't know about security.

I suggest using Interface (no need to use Class with constructor and so...), since you only have to create something like :

public interface ActivityClass {

    public static final String MYSTRING_1 = "STRING";

    public static final int MYINT_1 = 1;

}

Then you can access everywhere within your classes by using the following:

int myInt = ActivityClass.MYINT_1;
String myString = ActivityClass.MYSTRING_1;

The conventional way of handling this doesn't play well with ES6. You can do this instead:

$('.delete').on('click', event => {
  const clickedElement = $(event.target);

  this.delete(clickedElement.data('id'));
});

Note that the event target will be the clicked element, which may not be the element you want (it could be a child that received the event). To get the actual element:

$('.delete').on('click', event => {
  const clickedElement = $(event.target);
  const targetElement = clickedElement.closest('.delete');

  this.delete(targetElement.data('id'));
});

Perhaps you could try to use the of method of the Observable class:

import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';

public fetchModel(uuid: string = undefined): Observable<string> {
  if(!uuid) {
    return Observable.of(new TestModel()).map(o => JSON.stringify(o));
  }
  else {
    return this.http.get("http://localhost:8080/myapp/api/model/" + uuid)
            .map(res => res.text());
  }
}

Ok Check and Add to Watch:

1. Do a breakpoint at your ModelState line in your Code
2. Add your model state to your Watch
3. Expand ModelState "Values"
4. Expand Values "Results View"

Now you can see a list of all SubKey with its validation state at end of value.

So search for the Invalid value.

There is only workaround for the issue you are facing.

Check whether file id in process before starting the process of copy. You can call the following function until you get the False value.

1st Method, copied directly from this answer:

private bool IsFileLocked(FileInfo file)
{
    FileStream stream = null;

    try
    {
        stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None);
    }
    catch (IOException)
    {
        //the file is unavailable because it is:
        //still being written to
        //or being processed by another thread
        //or does not exist (has already been processed)
        return true;
    }
    finally
    {
        if (stream != null)
            stream.Close();
    }

    //file is not locked
    return false;
}

2nd Method:

const int ERROR_SHARING_VIOLATION = 32;
const int ERROR_LOCK_VIOLATION = 33;
private bool IsFileLocked(string file)
{
    //check that problem is not in destination file
    if (File.Exists(file) == true)
    {
        FileStream stream = null;
        try
        {
            stream = File.Open(file, FileMode.Open, FileAccess.ReadWrite, FileShare.None);
        }
        catch (Exception ex2)
        {
            //_log.WriteLog(ex2, "Error in checking whether file is locked " + file);
            int errorCode = Marshal.GetHRForException(ex2) & ((1 << 16) - 1);
            if ((ex2 is IOException) && (errorCode == ERROR_SHARING_VIOLATION || errorCode == ERROR_LOCK_VIOLATION))
            {
                return true;
            }
        }
        finally
        {
            if (stream != null)
                stream.Close();
        }
    }
    return false;
}

Empty just check is the refered variable/array has an value if you check the php doc(empty) you'll see this things are considered emtpy

* "" (an empty string)
* 0 (0 as an integer)
* "0" (0 as a string)
* NULL
* FALSE
* array() (an empty array)
* var $var; (a variable declared, but without a value in a class)

while isset check if the variable isset and not null which can also be found in the php doc(isset)

The way I do this is to git add this first then git stash apply <stash code>. It's the most simple way.

I don't know about the older versions but for SSMS 2016 you can go to the Object Explorer and right click on the Databases entry. Then select Attach... in the context menu. Here you can browse to the .mdf file and open it.

"%s%d%s%d\n" is the format string; it tells the printf function how to format and display the output. Anything in the format string that doesn't have a % immediately in front of it is displayed as is.

%s and %d are conversion specifiers; they tell printf how to interpret the remaining arguments. %s tells printf that the corresponding argument is to be treated as a string (in C terms, a 0-terminated sequence of char); the type of the corresponding argument must be char *. %d tells printf that the corresponding argument is to be treated as an integer value; the type of the corresponding argument must be int. Since you're coming from a Java background, it's important to note that printf (like other variadic functions) is relying on you to tell it what the types of the remaining arguments are. If the format string were "%d%s%d%s\n", printf would attempt to treat "Length of string" as an integer value and i as a string, with tragic results.

Try CSS3 Textshadow.

.box_textshadow {
     text-shadow: 2px 2px 0px #FF0000; /* FF3.5+, Opera 9+, Saf1+, Chrome, IE10 */
}

Try it yourself on css3please.com.

Since you declare sample inside the anonymous function you pass to ready, it is scoped to that function.

You then pass a string to setTimeout which is evaled after 2 seconds. This takes place outside the current scope, so it can't find the function.

Only pass functions to setTimeout, using eval is inefficient and hard to debug.

setTimeout(sample,2000)

I got this error when I modified an Nlog configuration file and didn't format the XML correctly.

Unless you use the <img> tag, which displays an image by itself, you will not be able to achieve this with pure CSS alone. You will also need TWO HTML elements as well - one for each picture. This is because the only way you can make an element display a picture via CSS is with the background-image property, and every element can have only one background image. Which two elements you choose and how you position them is up to you. There are many ways how you can position one HTML element above another.

instead of

                 ^

Unfortunately content projection into mat-form-field is not supported yet. Please track the following github issue to get the latest news about it.

By now the only solution for you is either place your content directly into mat-form-field component or implement a MatFormFieldControl class thus creating a custom form field component.

If you know you're on bash, and still get this error, make sure you write the if with spaces.

[[1==1]] # This outputs error

[[ 1==1 ]] # OK

After several attempts and going deep in Tomcat's source code I found out that the simple property useNaming="false" did the trick!! Now Tomcat resolves names java:/liferay instead of java:comp/env/liferay

Would like to add:

After update, such as

ALTER TABLE table_name modify column_name tinyint(4) NOT NULL;

If you get

ERROR 1138 (22004): Invalid use of NULL value

Make sure you update the table first to have values in the related column (so it's not null)

Tried with Selenium 3.141.0 and chromedriver 73.0.3683.68, this works,

from selenium import webdriver

chromedriver = '/usr/local/bin/chromedriver'
chromeOptions = webdriver.ChromeOptions()
chromeOptions.add_argument('window-size=1366x768')
chromeOptions.add_argument('disable-extensions')
cdriver = webdriver.Chrome(options=chromeOptions, executable_path=chromedriver)

cdriver.get('url')
element = cdriver.find_element_by_css_selector('.some-css.selector')

element.screenshot_as_png('elemenent.png')

No need to get a full image and get a section of a fullscreen image.

You could try my Linked Tree Map implementation.

$("#myid li").click(function() {
    alert(this.id); // id of clicked li by directly accessing DOMElement property
    alert($(this).attr('id')); // jQuery's .attr() method, same but more verbose
    alert($(this).html()); // gets innerHTML of clicked li
    alert($(this).text()); // gets text contents of clicked li
});

If you are talking about replacing the ID with something:

$("#myid li").click(function() {
    this.id = 'newId';

    // longer method using .attr()
    $(this).attr('id', 'newId');
});

Demo here. And to be fair, you should have first tried reading the documentation:

• http://api.jquery.com/category/selectors/
• http://api.jquery.com/category/events/
• http://api.jquery.com/attr/

Starting from jQuery UI 1.10.0, you can choose which input element to focus on by using the HTML5 attribute autofocus.

All you have to do is create a dummy element as your first input in the dialog box. It will absorb the focus for you.

<input type="hidden" autofocus="autofocus" />

This has been tested in Chrome, Firefox and Internet Explorer (all latest versions) on February 7, 2013.

This happens every time you insert/ update and you don't use single quotes. When the variable is empty it will result in that error. Fix it by using ''

Assuming the first parameter is an empty variable here is a simple example:

Wrong

nvl( ,0)

Fix

nvl('' ,0)

Put your query into your database software and check it for that error. Generally this is an easy fix

There could be a few things happening here. Start by first figuring out your library location:

Sys.getenv("R_LIBS_USER")

or

.libPaths()

We already know yours from the info you gave: C:\Program Files\R\R-3.0.1\library

I believe you have a file in there called: 00LOCK. From ?install.packages:

Note that it is possible for the package installation to fail so badly that the lock directory is not removed: this inhibits any further installs to the library directory (or for --pkglock, of the package) until the lock directory is removed manually.

You need to delete that file. If you had the pacman package installed you could have simply used p_unlock() and the 00LOCK file is removed. You can't install pacman now until the 00LOCK file is removed.

To install pacman use:

install.packages("pacman")

There may be a second issue. This is where you somehow corrupted MASS. This can occur, in my experience, if you try to update a package while it is in use in another R session. I'm sure there's other ways to cause this as well. To solve this problem try:

1. Close out of all R sessions (use task manager to ensure you're truly R session free) Ctrl + Alt + Delete
2. Go to your library location Sys.getenv("R_LIBS_USER"). In your case this is: C:\Program Files\R\R-3.0.1\library
3. Manually delete the MASS package
4. Fire up a vanilla session of R
5. Install MASS via install.packages("MASS")

If any of this works please let me know what worked.

for me problem was solved by,

sudo apt-get remove node
sudo apt-get remove nodejs
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs
sudo ln -s /usr/bin/nodejs /usr/bin/node
alias node=nodejs
rm -r /usr/local/lib/python2.7/dist-packages/localstack/node_modules
npm install -g npm@latest || sudo npm install -g npm@latest

Pandas 0.24.0+ solution

In Pandas 0.24.0 a new feature was introduced specifically designed for fast writes to Postgres. You can learn more about it here: https://pandas.pydata.org/pandas-docs/stable/user_guide/io.html#io-sql-method

import csv
from io import StringIO

from sqlalchemy import create_engine

def psql_insert_copy(table, conn, keys, data_iter):
    # gets a DBAPI connection that can provide a cursor
    dbapi_conn = conn.connection
    with dbapi_conn.cursor() as cur:
        s_buf = StringIO()
        writer = csv.writer(s_buf)
        writer.writerows(data_iter)
        s_buf.seek(0)

        columns = ', '.join('"{}"'.format(k) for k in keys)
        if table.schema:
            table_name = '{}.{}'.format(table.schema, table.name)
        else:
            table_name = table.name

        sql = 'COPY {} ({}) FROM STDIN WITH CSV'.format(
            table_name, columns)
        cur.copy_expert(sql=sql, file=s_buf)

engine = create_engine('postgresql://myusername:mypassword@myhost:5432/mydatabase')
df.to_sql('table_name', engine, method=psql_insert_copy)

Following example also capitalizes words after special characters such as [/-]

  public static String capitalize(String text) {
    char[] stringArray = text.trim().toCharArray();
    boolean wordStarted = false;
    for( int i = 0; i < stringArray.length; i++) {
      char ch = stringArray[i];
      if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z') || ch == '\'') {
        if( !wordStarted ) {
          stringArray[i] = Character.toUpperCase(stringArray[i]);
          wordStarted = true;
        } 
      } else {
        wordStarted = false;
      }
    }
    return new String(stringArray);
  }

Example:
capitalize("that's a beautiful/wonderful life we have.We really-do")

To count all rows in a table:

Controller:

function id_cont() {
   $news_data = new news_model();
   $ids=$news_data->data_model();
   print_r($ids);
}

Model:

function data_model() {
    $this->db->select('*');
    $this->db->from('news_data');
    $id = $this->db->get()->num_rows();
    return $id;
}

I've taken the liberty to put the macro by Macmade into a C function, and name it properly because it detects widescreen availability and NOT necessarily the iPhone 5.

The macro also doesn't detect running on an iPhone 5 in case where the project doesn't include the [email protected]. Without the new Default image, the iPhone 5 will report a regular 480x320 screen size (in points). So the check isn't just for widescreen availability but for widescreen mode being enabled as well.

BOOL isWidescreenEnabled()
{
    return (BOOL)(fabs((double)[UIScreen mainScreen].bounds.size.height - 
                                               (double)568) < DBL_EPSILON);
}

Yes there is a static nested class in java. When you declare a nested class static, it automatically becomes a stand alone class which can be instantiated without having to instantiate the outer class it belongs to.

Example:

public class A
{

 public static class B
 {
 }
}

Because class B is declared static you can explicitly instantiate as:

B b = new B();

Note if class B wasn't declared static to make it stand alone, an instance object call would've looked like this:

A a= new A();
B b = a.new B();

It might not be the best practice, but you can simply target a specific column using collect(), export it as a list of Rows, and loop through the list.

Assume this is your df:

+----------+----------+-------------------+-----------+-----------+------------------+ 
|      Date|  New_Date|      New_Timestamp|date_sub_10|date_add_10|time_diff_from_now|
+----------+----------+-------------------+-----------+-----------+------------------+

+----------+----------+-------------------+-----------+-----------+------------------+

to loop through rows in Date column:

rows = df3.select('Date').collect()

final_list = []
for i in rows:
    final_list.append(i[0])

print(final_list)

download InputSimulator from nuget package.

then write this:

        var simu = new InputSimulator();
        simu.Keyboard.ModifiedKeyStroke(VirtualKeyCode.LWIN, VirtualKeyCode.VK_E);

in my case to create new vertial desktop, 3 keys needed and code like this(windows key + ctrl + D):

        simu.Keyboard.ModifiedKeyStroke(new[] { VirtualKeyCode.LWIN, VirtualKeyCode.CONTROL }, VirtualKeyCode.VK_D);

If you want use RegEx in .NET,

Regex rx = new Regex(@"^([\w]+)(\-)*");
var match = rx.Match("thisis-thefirst");
var text = match.Groups[1].Value;
Assert.AreEqual("thisis", text);

None of the above answers worked for me. I have been 2 days working out the way to migrate a Vagrant + VirtualBox Machine from a computer to another... It's possible!

First, you need to understand that the virtual machine is separated from your sync / shared folder. So when you pack your machine you're packing it without your files, but with the databases.

What you need to do:

1- Open the CMD of your computer 1 host machine (Command line. Open it as Adminitrator with the right button -> "Run as administrator") and go to your vagrant installed files. On my case: C:/VVV You will see your Vagrantfile an also these folders:

/config/
/database/
/log/
/provision/
/www/
Vagrantfile
...

The /www/ folder is where I have my Sync Folder with my development domains. You may have your sync folder in other place, just be sure to understand what you are doing. Also /config and /database are sync folders.

2- run this command: vagrant package --vagrantfile Vagrantfile

(This command does a package of your virtual machine using you Vagrantfile configuration.)

Here's what you can read on the Vagrant documentation about the command:

A common misconception is that the --vagrantfile option will package a Vagrantfile that is used when vagrant init is used with this box. This is not the case. Instead, a Vagrantfile is loaded and read as part of the Vagrant load process when the box is used. For more information, read about the Vagrantfile load order.

https://www.vagrantup.com/docs/cli/package.html

When finnished, you will have a package.box file.

3- Copy all these files (/config, /database, Vagrantfile, package.box, etc.) and paste them on your Computer 2 just where you want to install your virtual machine (on my case D:/VVV).

Now you have a copy of everything you need on your computer 2 host.

4- run this: vagrant box add package.box --name VVV

(The --name is used to name your virtual machine. On my case it's named VVV) (You can use --force if you already have a virtual machine with this name and want to overwrite it. (Use carefully !))

This will unpack your new vagrant Virtual machine.

5- When finnished, run: vagrant up

The machine will install and you should see it on the "Oracle virtual machine box manager". If you cannot see the virtual machine, try running the Oracle VM box as administrator (right click -> Run as administrator)

You now may have everything ok but remember to see if your hosts are as you expected:

c:/windows/system32/hosts

6- Maybe it's a good idea to copy your host file from your Computer 1 to your Computer 2. Or copy the lines you need. In my case these are the hosts I need:

192.168.50.4 test.dev
192.168.50.4 vvv.dev
...

Where the 192.168.50.4 is the IP of my Virtual machine and test.dev and vvv.dev are developing hosts.

I hope this can help you :) I'll be happy if you feedback your go.

Some particularities of my case that you may find:

When I ran vagrant up, there was a problem with mysql, it wasn't working. I had to run on the Virtual server (right click on the oracle virtual machine -> Show console): apt-get install mysql-server

After this, I ran again vagrant up and everything was working but without data on the databases. So I did a mysqldump all-tables from the Computer 1 and upload them to Computer 2.

OTHER NOTES: My virtual machine is not exactly on Computer 1 and Computer 2. For example, I made some time ago internal configuration to use NFS (to speed up the server sync folders) and I needed to run again this command on the Computer 2 host: vagrant plugin install vagrant-winnfsd

They are different functions. You should decide for your situation what do you need.

I don't consider using any of them as a bad practice. Most of the time IsNullOrEmpty() is enough. But you have the choice :)

A lot of the old TextFX operations like removing empty lines and sorting are available under:

Menu Edit ? Line Operations

Command line arguments are stored as strings in the String array String[] args that is passed tomain()`.

java [program name] [arg1,arg2 ,..]

Command line arguments are the inputs that accept from the command prompt while running the program. The arguments passed can be anything. Which is stored in the args[] array.

//Display all command line information
         class ArgDemo{
            public static void main(String args[]){
            System.out.println("there are "+args.length+"command-line arguments.");
            for(int i=0;i<args.length;i++)
            System.out.println("args["+i+"]:"+args[i]);
    }
    }

Example:

java Argdemo one two

The output will be:

there are 2 command line arguments:
they are:
arg[0]:one
arg[1]:two

{{yourDate|date:'*Prefered Format*'}}

Example:

{{yourDate|date:'F d, Y'}}

For preferred format: https://docs.djangoproject.com/en/3.1/ref/templates/builtins/#date

Another way is make your <a> full fill all the space of the panel-heading. Use this style to do so:

.panel-title a {
    display: block;
    padding: 10px 15px;
    margin: -10px -15px;
}

Check this demo (http://jsfiddle.net/KbQyx/).

Then when you clicking on the heading, you are actually clicking on the <a>.

Modifying styles directly in range or cells did not work for me. But the idea to:

1. create a separate style
2. apply all the necessary style property values
3. set the style's name to the Style property of the range

, given in MSDN How to: Programmatically Apply Styles to Ranges in Workbooks did the job.

For example:

var range = worksheet.Range[string.Format("A{0}:C{0}", rowIndex++)];
range.Merge();
range.Value = "some value";

var style = workbook.AddStyle();
style.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignLeft;

range.Style = style.Name;

I was having this issue and fixed it by going to: C:\Dev-Cpp\libexec\gcc\mingw32\3.4.2 , then deleting collect2.exe

**multiple delete not working**

function delete_selection() 
{
        $id_array = array();
        $selection = $this->input->post("selection", TRUE);
        $id_array = explode("|", $selection);

        foreach ($id_array as $item):
            if ($item != ''):
                //DELETE ROW
                $this->db->where('entry_id', $item);
                $this->db->delete('helpline_entry');
            endif;
        endforeach;
    }

for API Level 11 or above:

case TelephonyManager.PHONE_TYPE_SIP: 
return "SIP";

TelephonyManager tm= (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
textDeviceID.setText(getDeviceID(tm));

and if you want to check div has a perticular children(say <p> use:

if ($('#myfav').children('p').length > 0) {
     // do something
}

When your XHR request returns a Redirect response (HTTP Status 301, 302, 303, 307), the XMLHttpRequest automatically follows the redirected URL and returns the status code of that URL.

You can get the non-redirecting status codes (200, 400, 500 etc) via the status property of the xhr object.

So you cannot get the redirected location from the response header of a 301, 302, 303 or 307 request.

You might have to change your server logic to respond in a way that you can handle the redirect, rather than letting the browser do it. An example implementation.

I've had to try to 'fix' a number of UTF8 broken situations in the past, and unfortunately it's never easy, and often rather impossible.

Unless you can determine exactly how it was broken, and it was always broken in that exact same way, then it's going to be hard to 'undo' the damage.

If you want to try to undo the damage, your best bet would be to start writing some sample code, where you attempt numerous variations on calls to mb_convert_encoding() to see if you can find a combination of 'from' and 'to' that fixes your data. In the end, it's often best to not even bother worrying about fixing the old data because of the pain levels involved, but instead to just fix things going forward.

However, before doing this, you need to make sure that you fix everything that is causing this issue in the first place. You've already mentioned that your DB table collation and editors are set properly. But there are more places where you need to check to make sure that everything is properly UTF-8:

• Make sure that you are serving your HTML as UTF-8:
  • header("Content-Type: text/html; charset=utf-8");
• Change your PHP default charset to utf-8:
  • ini_set("default_charset", 'utf-8');
• If your database doesn't ALWAYS talk in utf-8, then you may need to tell it on a per connection basis to ensure it's in utf-8 mode, in MySQL you do that by issuing:
  • charset utf8
• You may need to tell your webserver to always try to talk in UTF8, in Apache this command is:
  • AddDefaultCharset UTF-8
• Finally, you need to ALWAYS make sure that you are using PHP functions that are properly UTF-8 complaint. This means always using the mb_* styled 'multibyte aware' string functions. It also means when calling functions such as htmlspecialchars(), that you include the appropriate 'utf-8' charset parameter at the end to make sure that it doesn't encode them incorrectly.

If you miss up on any one step through your whole process, the encoding can be mangled and problems arise. Once you get in the 'groove' of doing utf-8 though, this all becomes second nature. And of course, PHP6 is supposed to be fully unicode complaint from the getgo, which will make lots of this easier (hopefully)

Another thing which worked was -

1. Manually delete & then Create a designer file in filesystem.
2. Edit Project file.
3. Add code to include designer
   Eg: <Compile Include="<Path>\FileName.ascx.designer.cs"> <DependentUpon>FileName.ascx</DependentUpon> </Compile>
4. Reload Project
5. Open as(c/p)x file in design/view mode & save it.
6. Check designer file. Code will be there.

You can use this

"abcdefg".index('c')   #=> 2

Beware of using string interpolation for SQL queries, since it won't escape the input parameters correctly and will leave your application open to SQL injection vulnerabilities. The difference might seem trivial, but in reality it's huge.

Incorrect (with security issues)

c.execute("SELECT * FROM foo WHERE bar = %s AND baz = %s" % (param1, param2))

Correct (with escaping)

c.execute("SELECT * FROM foo WHERE bar = %s AND baz = %s", (param1, param2))

It adds to the confusion that the modifiers used to bind parameters in a SQL statement varies between different DB API implementations and that the mysql client library uses printf style syntax instead of the more commonly accepted '?' marker (used by eg. python-sqlite).

Double defined constants

To fix the specific error here you can check if a constant is already defined before defining it:

if ( ! defined( 'DIR_FS_CATALOG' ) ) 
  define( 'DIR_FS_CATALOG', 'something...' );

I'd personally start with a search in the codebase for the constant DIR_FS_CATALOG, then replace the double definition with this.

Hiding PHP notices inline, case-by-case

PHP provides the @ error control operator, which you can use to ignore specific functions that cause notices or warnings.

Using this you can ignore/disable notices and warnings on a case-by-case basis in your code, which can be useful for situations where an error or notice is intentional, planned, or just downright annoying and not possible to solve at the source. Place an @ before the function or var that's causing a notice and it will be ignored.

Here's an example:

// Intentional file error
$missing_file = @file( 'non_existent_file' );

More on this can be found in PHP's Error Control Operators docs.

How to find out the document width and height very easily?

in HTML
<span id="hidden_placer" style="position:absolute;right:0;bottom:0;visibility:hidden;"></span>

in javascript

     var c=document.querySelector('#hidden_placer');

     var r=c.getBoundingClientRect();
     r.right=document width
     r.bottom=document height`

You may update this on every window resize event, if needed.

Very easy, just wrap the table in a div that has overflow-y:scroll; and overflow-x:scroll properties, and make the div have a width and length smaller than the table. IT WILL WORK!!!

For individual variables you want to make available on a one off basis you can make it part of the command.

sudo http_proxy=$http_proxy wget "http://stackoverflow.com"

>>> l = [1,2,3,4,5,6]

>>> zip(l,l[1:])
[(1, 2), (2, 3), (3, 4), (4, 5), (5, 6)]

>>> zip(l,l[1:])[::2]
[(1, 2), (3, 4), (5, 6)]

>>> [a+b for a,b in zip(l,l[1:])[::2]]
[3, 7, 11]

>>> ["%d + %d = %d" % (a,b,a+b) for a,b in zip(l,l[1:])[::2]]
['1 + 2 = 3', '3 + 4 = 7', '5 + 6 = 11']

I think that CONTAINS took longer and used Merge because you had a dash("-") in your query adventure-works.com.

The dash is a break word so the CONTAINS searched the full-text index for adventure and than it searched for works.com and merged the results.

For the most updated version 2.71828 These are your answer.

Q1: Does it not have local disk cache?

A1: There is default caching within Picasso and the request flow just like this

App -> Memory -> Disk -> Server

Wherever they met their image first, they'll use that image and then stop the request flow. What about response flow? Don't worry, here it is.

Server -> Disk -> Memory -> App

By default, they will store into a local disk first for the extended keeping cache. Then the memory, for the instance usage of the cache.

You can use the built-in indicator in Picasso to see where images form by enabling this.

Picasso.get().setIndicatorEnabled(true);

It will show up a flag on the top left corner of your pictures.

• Red flag means the images come from the server. (No caching at first load)
• Blue flag means the photos come from the local disk. (Caching)
• Green flag means the images come from the memory. (Instance Caching)

Q2: How do I enable disk caching as I will be using the same image multiple times?

A2: You don't have to enable it. It's the default.

What you'll need to do is DISABLE it when you want your images always fresh. There is 2-way of disabled caching.

1. Set .memoryPolicy() to NO_CACHE and/or NO_STORE and the flow will look like this.

NO_CACHE will skip looking up images from memory.

App -> Disk -> Server

NO_STORE will skip store images in memory when the first load images.

Server -> Disk -> App

2. Set .networkPolicy() to NO_CACHE and/or NO_STORE and the flow will look like this.

NO_CACHE will skip looking up images from disk.

App -> Memory -> Server

NO_STORE will skip store images in the disk when the first load images.

Server -> Memory -> App

You can DISABLE neither for fully no caching images. Here is an example.

Picasso.get().load(imageUrl)
             .memoryPolicy(MemoryPolicy.NO_CACHE,MemoryPolicy.NO_STORE)
             .networkPolicy(NetworkPolicy.NO_CACHE, NetworkPolicy.NO_STORE)
             .fit().into(banner);

The flow of fully no caching and no storing will look like this.

App -> Server //Request

Server -> App //Response

So, you may need this to minify your app storage usage also.

Q3: Do I need to add some disk permission to android manifest file?

A3: No, but don't forget to add the INTERNET permission for your HTTP request.

The behaviour should depend on how the browser is set up to handle various MIME types. In this case the MIME type is application/pdf. If you want to force the browser to download the file you can try forcing a different MIME type on the PDF files. I recommend against this as it should be the users choice what will happen when they open a PDF file.

Not only can you, but you have to make a special effort not to if you don't want to. :-)

When the browser encounters a classic script tag when parsing the HTML, it stops parsing and hands over to the JavaScript interpreter, which runs the script. The parser doesn't continue until the script execution is complete (because the script might do document.write calls to output markup that the parser should handle).

That's the default behavior, but you have a few options for delaying script execution:

1. Use JavaScript modules. A type="module" script is deferred until the HTML has been fully parsed and the initial DOM created. This isn't the primary reason to use modules, but it's one of the reasons:

   <script type="module" src="./my-code.js"></script>
   <!-- Or -->
   <script type="module">
   // Your code here
   </script>
   

   The code will be fetched (if it's separate) and parsed in parallel with the HTML parsing, but won't be run until the HTML parsing is done. (If your module code is inline rather than in its own file, it is also deferred until HTML parsing is complete.)

   This wasn't available when I first wrote this answer in 2010, but here in 2020, all major modern browsers support modules natively, and if you need to support older browsers, you can use bundlers like Webpack and Rollup.js.

2. Use the defer attribute on a classic script tag:

   <script defer src="./my-code.js"></script>
   

   As with the module, the code in my-code.js will be fetched and parsed in parallel with the HTML parsing, but won't be run until the HTML parsing is done. But, defer doesn't work with inline script content, only with external files referenced via src.

3. I don't think it's what you want, but you can use the async attribute to tell the browser to fetch the JavaScript code in parallel with the HTML parsing, but then run it as soon as possible, even if the HTML parsing isn't complete. You can put it on a type="module" tag, or use it instead of defer on a classic script tag.

4. Put the script tag at the end of the document, just prior to the closing </body> tag:

   <!doctype html>
   <html>
   <!-- ... -->
   <body>
   <!-- The document's HTML goes here -->
   <script type="module" src="./my-code.js"></script><!-- Or inline script -->
   </body>
   </html>
   

   That way, even though the code is run as soon as its encountered, all of the elements defined by the HTML above it exist and are ready to be used.

   It used to be that this caused an additional delay on some browsers because they wouldn't start fetching the code until the script tag was encountered, but modern browsers scan ahead and start prefetching. Still, this is very much the third choice at this point, both modules and defer are better options.

The spec has a useful diagram showing a raw script tag, defer, async, type="module", and type="module" async and the timing of when the JavaScript code is fetched and run:

Here's an example of the default behavior, a raw script tag:

.found {_x000D_
    color: green;_x000D_
}

<p>Paragraph 1</p>_x000D_
<script>_x000D_
    if (typeof NodeList !== "undefined" && !NodeList.prototype.forEach) {_x000D_
        NodeList.prototype.forEach = Array.prototype.forEach;_x000D_
    }_x000D_
    document.querySelectorAll("p").forEach(p => {_x000D_
        p.classList.add("found");_x000D_
    });_x000D_
</script>_x000D_
<p>Paragraph 2</p>

(See my answer here for details around that NodeList code.)

When you run that, you see "Paragraph 1" in green but "Paragraph 2" is black, because the script ran synchronously with the HTML parsing, and so it only found the first paragraph, not the second.

In contrast, here's a type="module" script:

.found {_x000D_
    color: green;_x000D_
}

<p>Paragraph 1</p>_x000D_
<script type="module">_x000D_
    document.querySelectorAll("p").forEach(p => {_x000D_
        p.classList.add("found");_x000D_
    });_x000D_
</script>_x000D_
<p>Paragraph 2</p>

Notice how they're both green now; the code didn't run until HTML parsing was complete. That would also be true with a defer script with external content (but not inline content).

(There was no need for the NodeList check there because any modern browser supporting modules already has forEach on NodeList.)

In this modern world, there's no real value to the DOMContentLoaded event of the "ready" feature that PrototypeJS, jQuery, ExtJS, Dojo, and most others provided back in the day (and still provide); just use modules or defer. Even back in the day, there wasn't much reason for using them (and they were often used incorrectly, holding up page presentation while the entire jQuery library was loaded because the script was in the head instead of after the document), something some developers at Google flagged up early on. This was also part of the reason for the YUI recommendation to put scripts at the end of the body, again back in the day.

In my case I was using XAMPP, and there was a log that told me the error. To find it, go to the XAMPP control panel, and click "Configure" for MySQL, then click on "Open Log."

The most current data of the log is at the bottom, and the log is organized by date, time, some number, and text in brackets that may say "Note" or "Error." One that says "Error" is likely causing the issue.

For me, my error was a tablespace that was causing an issue, so I deleted the database files at the given location.

Note: The tablespace files for your installation of XAMPP may be at a different location, but they were in /opt/lampp/var/mysql for me. I think that's typical of XAMPP on Debian-based distributions. Also, my instructions on what to click in the control panel to see the log may be a bit different for you because I'm running XAMPP on an Ubuntu-based distribution of Linux (Feren OS).

NOTE: In 2016, you can probably use flexbox to solve this problem easier.

This method works correctly IE7+ and all major browsers, it's been tried and tested in a number of complex viewport-based web applications.

<style>
    .container {
        font-size: 0;
    }

    .ie7 .column {
        font-size: 16px; 
        display: inline; 
        zoom: 1;
    }

    .ie8 .column {
        font-size:16px;
    }

    .ie9_and_newer .column { 
        display: inline-block; 
        width: 50%; 
        font-size: 1rem;
    }
</style>

<div class="container">
    <div class="column">text that can wrap</div>
    <div class="column">text that can wrap</div>
</div>

Live demo: http://output.jsbin.com/sekeco/2

The only downside to this method for IE7/8, is relying on body {font-size:??px} as basis for em/%-based font-sizing.

IE7/IE8 specific CSS could be served using IE's Conditional comments

For any React Router v4 users arriving here following a search, optional parameters in a <Route> are denoted with a ? suffix.

Here's the relevant documentation:

https://reacttraining.com/react-router/web/api/Route/path-string

path: string

Any valid URL path that path-to-regexp understands.

    <Route path="/users/:id" component={User}/>

https://www.npmjs.com/package/path-to-regexp#optional

Optional

Parameters can be suffixed with a question mark (?) to make the parameter optional. This will also make the prefix optional.

Simple example of a paginated section of a site that can be accessed with or without a page number.

    <Route path="/section/:page?" component={Section} />

If angular cli is installed and ng command is not working then please see below suggestion, it may work

In my case problem was with npm config file (.npmrc ) which is available at C:\Users{user}. That file does not contain line registry https://registry.npmjs.org/=true. When i have added that line command started working. Use below command to edit config file. Edit file and save. Try to run command again. It should work now.

npm config edit

Arrays.fill might suit your needs

Using jQuery the easiest will be:

var text = '<p>name</p><p><span style="font-size:xx-small;">ajde</span></p><p><em>da</em></p>';

var output = $("<div />").html(text).text();
console.log(output);

I'd download PuTTY and run a telnet session on port 80 to the webserver you want

HEAD /resource HTTP/1.1
Host: www.example.com

You could alternatively download Perl and try LWP's HEAD command. Or write your own script.

Let us assume:

• Your file system is distributed
• Your file system can easily fill the network connection to a single node
• You access your files like normal files

then you really want to chop the files into parts, count parts in parallel on multiple nodes and sum up the results from there (this is basically @Chris White's idea).

Here is how you do that with GNU Parallel (version > 20161222). You need to list the nodes in ~/.parallel/my_cluster_hosts and you must have ssh access to all of them:

parwc() {
    # Usage:
    #   parwc -l file                                                                

    # Give one chunck per host                                                     
    chunks=$(cat ~/.parallel/my_cluster_hosts|wc -l)
    # Build commands that take a chunk each and do 'wc' on that                    
    # ("map")                                                                      
    parallel -j $chunks --block -1 --pipepart -a "$2" -vv --dryrun wc "$1" |
        # For each command                                                         
        #   log into a cluster host                                                
        #   cd to current working dir                                              
        #   execute the command                                                    
        parallel -j0 --slf my_cluster_hosts --wd . |
        # Sum up the number of lines                                               
        # ("reduce")                                                               
        perl -ne '$sum += $_; END { print $sum,"\n" }'
}

Use as:

parwc -l myfile
parwc -w myfile
parwc -c myfile

From the project directory type the following:

Deleting all .pyc files

find . -path "*/*.pyc" -delete

Deleting all .pyo files:

find . -path "*/*.pyo" -delete

Finally, to delete all '__pycache__', type:

find . -path "*/__pycache__" -type d -exec rm -r {} ';'

If you encounter permission denied error, add sudo at the begining of all the above command.

in code

listView.setSelector(getResources().getDrawable(R.drawable.transparent));

and add small transparent image to drawable folder.

Like: transparent.xml

<?xml version="1.0" encoding="utf-8"?>    
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#00000000"/>
</shape>

You need parentheses:

print(2**100)

Probably because you forgot to implement the solution in the accepted answer. That's the code that makes trim() work.

update

This answer only applies to older browsers. Newer browsers apparently support trim() natively.

I second Blindy's suggestion to use the MAC address of the (first?) network adapter. Yes, the MAC address can be spoofed, but this has side effects (you don't want two PCs with the same MAC address in the same network), and it's something that "your average pirate" won't do just to be able to use your software. Considering that there's no 100% solution against software piracy, the MAC address is a good compromise, IMO.

Note, however, that the address will change when the user adds, replaces or removes a network card (or replaces his old PC altogether), so be prepared to help your customers and give them a new key when they change their hardware configuration.

How do I test whether an element has perticular class or not

There are two types of LinearSegmentedColormaps. In some, the _segmentdata is given explicitly, e.g., for jet:

>>> cm.jet._segmentdata
{'blue': ((0.0, 0.5, 0.5), (0.11, 1, 1), (0.34, 1, 1), (0.65, 0, 0), (1, 0, 0)), 'red': ((0.0, 0, 0), (0.35, 0, 0), (0.66, 1, 1), (0.89, 1, 1), (1, 0.5, 0.5)), 'green': ((0.0, 0, 0), (0.125, 0, 0), (0.375, 1, 1), (0.64, 1, 1), (0.91, 0, 0), (1, 0, 0))}

For rainbow, _segmentdata is given as follows:

>>> cm.rainbow._segmentdata
{'blue': <function <lambda> at 0x7fac32ac2b70>, 'red': <function <lambda> at 0x7fac32ac7840>, 'green': <function <lambda> at 0x7fac32ac2d08>}

We can find the functions in the source of matplotlib, where they are given as

_rainbow_data = {
        'red': gfunc[33],   # 33: lambda x: np.abs(2 * x - 0.5),
        'green': gfunc[13], # 13: lambda x: np.sin(x * np.pi),
        'blue': gfunc[10],  # 10: lambda x: np.cos(x * np.pi / 2)
}

Everything you want is already done in matplotlib, just call cm.revcmap, which reverses both types of segmentdata, so

cm.revcmap(cm.rainbow._segmentdata)

should do the job - you can simply create a new LinearSegmentData from that. In revcmap, the reversal of function based SegmentData is done with

def _reverser(f):
    def freversed(x):
        return f(1 - x)
    return freversed

while the other lists are reversed as usual

valnew = [(1.0 - x, y1, y0) for x, y0, y1 in reversed(val)] 

So actually the whole thing you want, is

def reverse_colourmap(cmap, name = 'my_cmap_r'):
     return mpl.colors.LinearSegmentedColormap(name, cm.revcmap(cmap._segmentdata)) 

Basically git commit "records changes to the repository" while git push "updates remote refs along with associated objects". So the first one is used in connection with your local repository, while the latter one is used to interact with a remote repository.

Here is a nice picture from Oliver Steele, that explains the git model and the commands:

HTTP Servers tend to reject old browsers and systems.

The page Tech Blog (wh): Most Common User Agents reflects the user-agent property of your current browser in section "Your user agent is:", which can be applied to set the request property "User-Agent" of a java.net.URLConnection or the system property "http.agent".

Don't forget to return the mapped array , like:

lapsList() {

    return this.state.laps.map((data) => {
      return (
        <View><Text>{data.time}</Text></View>
      )
    })

}

Reference for the map() method: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map

One could simply use this

MyControl.Margin = new System.Windows.Thickness(10, 0, 5, 0);

The jQuery documentation has a link to this article 'Basic usage of the jQuery UI dialog' that explains this situation and how to resolve it.

head -1 file.tsv |head -1 train.tsv |tr '\t' '\n' |wc -l

take the first line, change tabs (or you can use ',' instead of '\t' for commas), count the number of lines.

NSNumber *lat = [NSNumber numberWithDouble:destinationMapView.camera.target.latitude];
NSNumber *lon = [NSNumber numberWithDouble:destinationMapView.camera.target.longitude];
NSString *DesconCatenated = [NSString stringWithFormat:@"%@|%@",lat,lon];

I was able to SSH from one machine, but not from another. Turns out I was using the wrong private key.

The way I figured this out was by getting the public key from my private key, like this:

ssh-keygen -y -f ./myprivatekey.pem

What came out didn't match what was in ~/.ssh/authorized_keys on the EC2 instance.

Take a look at algorithms package, especially the algorithm environment.

why not simply eg

var newList = list1.Union(list2)/*.Distinct()*//*.ToList()*/;

oh ... according to the documentation you can leave out the .Distinct()

This method excludes duplicates from the return set

It's about the ABI, in order to let both C and C++ application use C interfaces without any issue.

Since C language is very easy, code generation was stable for many years for different compilers, such as GCC, Borland C\C++, MSVC etc.

While C++ becomes more and more popular, a lot things must be added into the new C++ domain (for example finally the Cfront was abandoned at AT&T because C could not cover all the features it needs). Such as template feature, and compilation-time code generation, from the past, the different compiler vendors actually did the actual implementation of C++ compiler and linker separately, the actual ABIs are not compatible at all to the C++ program at different platforms.

People might still like to implement the actual program in C++ but still keep the old C interface and ABI as usual, the header file has to declare extern "C" {}, it tells the compiler generate compatible/old/simple/easy C ABI for the interface functions if the compiler is C compiler not C++ compiler.

I have used Mockito.verify in this way

@UnitTest
public class JUnitServiceTest
{
    @Mock
    private MyCustomService myCustomService;


    @Test
    public void testVerifyMethod()
    {
       Mockito.verify(myCustomService, Mockito.never()).mymethod(parameters); // method will never call (an alternative can be pick to use times(0))
       Mockito.verify(myCustomService, Mockito.times(2)).mymethod(parameters); // method will call for 2 times
       Mockito.verify(myCustomService, Mockito.atLeastOnce()).mymethod(parameters); // method will call atleast 1 time
       Mockito.verify(myCustomService, Mockito.atLeast(2)).mymethod(parameters); // method will call atleast 2 times
       Mockito.verify(myCustomService, Mockito.atMost(3)).mymethod(parameters); // method will call at most 3 times
       Mockito.verify(myCustomService, Mockito.only()).mymethod(parameters); //   no other method called except this
    }
}

You need declare class Contract

class Contract {
  public $id;
  public $name;
}

$contract = new Contract();
$contract->id = 100;
$contract->name = "John";

$params = array(
  "Contact" => $contract,
  "description" => "Barrel of Oil",
  "amount" => 500,
);

or

$params = array(
  $contract,
  "description" => "Barrel of Oil",
  "amount" => 500,
);

Then

$response = $client->__soapCall("Function1", array("FirstFunction" => $params));

or

$response = $client->__soapCall("Function1", $params);

I use svnX (http://code.google.com/p/svnx/downloads/list), it is free and usable, but not as user friendly as tortoise. It shows you the review before commit with diff for every file... but sometimes I still had to go to command line to fix some things

string strData = "This is much easier"
int intDelimiterIndx = strData.IndexOf("is");
int intDelimiterLength = "is".Length;
str1 = strData.Substring(0, intDelimiterIndx);
str2 = strData.Substring(intDelimiterIndx + intDelimiterLength, strData.Length - (intDelimiterIndx + intDelimiterLength));

Using Clay.js (https://github.com/zzarcon/clay) it's quite simple to detect changes on element size:

var el = new Clay('.element');

el.on('resize', function(size) {
    console.log(size.height, size.width);
});

Change this...

var string = document.location;

to this...

var string = document.location + '';

This is because document.location is a Location object. The default .toString() returns the location in string form, so the concatenation will trigger that.

You could also use document.URL to get a string.

I had a similar problem.

When I entered

<activity android:name="MyActivity" android:screenOrientation="landscape"></activity>

In the manifest file this caused that activity to display in landscape. However when I returned to previous activities they displayed in lanscape even though they were set to portrait. However by adding

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

immediately after the OnCreate section of the target activity resolved the problem. So I now use both methods.

You should better verify where you get that list from.

An empty list is all you need, because an empty list won't fail.

If you get this list from somewhere else and don't know if it is ok or not you could create a utility method and use it like this:

for( Object o : safe( list ) ) {
   // do whatever 
 }

And of course safe would be:

public static List safe( List other ) {
    return other == null ? Collections.EMPTY_LIST : other;
}

Good answers from gdw2 and d5e5. To make it a little simpler here are the recommendations pulled together in a single series of commands:

sqlite> .mode csv
sqlite> .output test.csv
sqlite> select * from tbl1;
sqlite> .output stdout

You have to use GROUP BY so you will have multiple records returned,

SELECT  COUNT(*) TotalCount, 
        b.category_id, 
        b.category_name 
FROM    table1 a
        INNER JOIN table2 b
            ON a.category_id = b.category_id 
WHERE   a.colour <> 'red'
GROUP   BY b.category_id, b.category_name

Actually the C++ standard (i.e. C++ 0x draft) says (tnx to @Xeo & @Ben Voigt for pointing that out to me):

23.2.4 Associative containers
5 For set and multiset the value type is the same as the key type. For map and multimap it is equal to pair. Keys in an associative container are immutable.
6 iterator of an associative container is of the bidirectional iterator category. For associative containers where the value type is the same as the key type, both iterator and const_iterator are constant iterators. It is unspecified whether or not iterator and const_iterator are the same type.

So VC++ 2008 Dinkumware implementation is faulty.

Old answer:

You got that error because in certain implementations of the std lib the set::iterator is the same as set::const_iterator.

For example libstdc++ (shipped with g++) has it (see here for the entire source code):

typedef typename _Rep_type::const_iterator            iterator;
typedef typename _Rep_type::const_iterator            const_iterator;

And in SGI's docs it states:

iterator       Container  Iterator used to iterate through a set.
const_iterator Container  Const iterator used to iterate through a set. (Iterator and const_iterator are the same type.)

On the other hand VC++ 2008 Express compiles your code without complaining that you're calling non const methods on set::iterators.

you should just remove the 'boolean' in front of your boolean variable.

Do it like this:

boolean isLeapYear = true;
System.out.println(isLeapYear);

or

boolean isLeapYear = true;
System.out.println(isLeapYear?"yes":"no");

The other thing ist hat you seems not to call the method at all! The method and the variable are both not static, thus, you have to create an instance of your class first. Or you just make both static and than simply call your method directly from your maim method.

Thus there are a couple of mistakes in the code. May be you shoud start with a more simple example and than rework it until it does what you want.

Example:

import java.util.Scanner;

public class booleanfun    {
    static boolean isLeapYear;

    public static void main(String[] args)
    {
        System.out.println("Enter a year to determine if it is a leap year or not: ");
        Scanner kboard = new Scanner(System.in);
        int year = kboard.nextInt();
        isLeapYear(year);
    }
    public static boolean isLeapYear(int year) {
        if (year % 4 != 0)
        isLeapYear = false;

        else if ((year % 4 == 0) && (year % 100 == 0))

        isLeapYear = false;

        else if ((year % 4 == 0) && (year % 100 == 0) && (year % 400 == 0))
            isLeapYear = true;

        else
            isLeapYear = false;

        System.out.println(isLeapYear);

        return isLeapYear;
    }
}

You have mentioned "user" twice in your FROM clause. You must provide a table alias to at least one mention so each mention of user. can be pinned to one or the other instance:

FROM article INNER JOIN section
ON article.section_id = section.id
INNER JOIN category ON article.category_id = category.id
INNER JOIN user **AS user1** ON article.author\_id = **user1**.id
LEFT JOIN user **AS user2** ON article.modified\_by = **user2**.id
WHERE article.id = '1'

(You may need something different - I guessed which user is which, but the SQL engine won't guess.)

Also, maybe you only needed one "user". Who knows?

You could consider creating your files using the XML Spreadsheet 2003 format. This is a simple XML format using a well documented schema.

Unfortunately, strptime() can only handle the timezone configured by your OS, and then only as a time offset, really. From the documentation:

Support for the %Z directive is based on the values contained in tzname and whether daylight is true. Because of this, it is platform-specific except for recognizing UTC and GMT which are always known (and are considered to be non-daylight savings timezones).

strftime() doesn't officially support %z.

You are stuck with python-dateutil to support timezone parsing, I am afraid.

For spring :

File inputFile = new ClassPathResource("\\chrome\\chromedriver.exe").getFile();
System.setProperty("webdriver.chrome.driver",inputFile.getCanonicalPath());

Do you mean something like this:

s1 = '00000001'
s2 = '11111110'
int(s1,2) ^ int(s2,2)

<style>
a{
cursor: default;
}
</style>

In the above code [cursor:default] is used. Default is the usual arrow cursor that appears.

And if you use [cursor: pointer] then you can access to the hand like cursor that appears when you hover over a link.

To know more about cursors and their appearance click the below link: https://www.w3schools.com/cssref/pr_class_cursor.asp

In Postgresql:

select *
from comments
where id in (1,3,2,4)
order by position(id::text in '1,3,2,4')

If you want to have a new data frame then:

import pandas as pd
old = pd.DataFrame({'A' : [4,5], 'B' : [10,20], 'C' : [100,50], 'D' : [-30,-50]})
new=  old[['A', 'C', 'D']]

just use replace:

In [106]:
df.replace('N/A',np.NaN)

Out[106]:
    x    y
0  10   12
1  50   11
2  18  NaN
3  32   13
4  47   15
5  20  NaN

What you're trying is called chain indexing: http://pandas.pydata.org/pandas-docs/stable/indexing.html#indexing-view-versus-copy

You can use loc to ensure you operate on the original dF:

In [108]:
df.loc[df['y'] == 'N/A','y'] = np.nan
df

Out[108]:
    x    y
0  10   12
1  50   11
2  18  NaN
3  32   13
4  47   15
5  20  NaN

SELECT * FROM 
(SELECT [UserID] FROM [User]) a
LEFT JOIN (SELECT [TailUser], [Weight] FROM [Edge] WHERE [HeadUser] = 5043) b
ON a.UserId = b.TailUser

pdf2htmlEX by coolwanglu is probably the best solution out there to convert a pdf file into html. You could do a simple convert and then embed the html page as an iframe or something similar.

I don't know what version of CI you were using back in 2013, but I am using CI3 and I just tested with two null parameters passed to limit() and there was no LIMIT or OFFSET in the rendered query (I checked by using get_compiled_select()).

This means that -- assuming your have correctly posted your coding attempt -- you don't need to change anything (or at least the old issue is no longer a CI issue).

If this was my project, this is how I would write the method to return an indexed array of objects or an empty array if there are no qualifying rows in the result set.

function nationList($limit = null, $start = null) {
    // assuming the language value is sanitized/validated/whitelisted
    return $this->db
        ->select('nation.id, nation.name_' . $this->session->userdata('language') . ' AS name')
        ->from('nation')
        ->order_by("name")
        ->limit($limit, $start)
        ->get()
        ->result();
}

These refinements remove unnecessary syntax, conditions, and the redundant loop.

For reference, here is the CI core code:

/**
 * LIMIT
 *
 * @param   int $value  LIMIT value
 * @param   int $offset OFFSET value
 * @return  CI_DB_query_builder
 */
public function limit($value, $offset = 0)
{
    is_null($value) OR $this->qb_limit = (int) $value;
    empty($offset) OR $this->qb_offset = (int) $offset;

    return $this;
}

So the $this->qb_limit and $this->qb_offset class objects are not updated because null evaluates as true when fed to is_null() or empty().

One major difference that is important to know is that ActiveX controls show up as objects that you can use in your code- try inserting an ActiveX control into a worksheet, bring up the VBA editor (ALT + F11) and you will be able to access the control programatically. You can't do this with form controls (macros must instead be explicitly assigned to each control), but form controls are a little easier to use. If you are just doing something simple, it doesn't matter which you use but for more advanced scripts ActiveX has better possibilities.

ActiveX is also more customizable.

I faced this issue but after 2 days I got a solution. Just run these two commands if you are deploying your site on GitHub pages first time.

git commit -m "initial commit"
git push origin +HEAD

you can use the weight value specified in the Google Fonts.

Click on the top most project name in the left hand file explorer (it should have a little blueprint icon). In the center column click on your project name under 'TARGETS', (it should have a little pencil 'A' icon next to it). Look under 'iPhone / iPod Deployment Info' and look for 'Main Interface'. You should be able to select an option from the drop down.

Don't forget to look at the Javascript as well. My guess is that there is custom Javascript code getting executed when you click on the link and it's that Javascript that is generating the URL and navigating to it.

    String s = "java is an object oriented programming language.";      
    final StringBuilder result = new StringBuilder(s.length());    
    String words[] = s.split("\\ "); // space found then split it  
    for (int i = 0; i < words.length; i++) 
         {
    if (i > 0){
    result.append(" ");
    }   
    result.append(Character.toUpperCase(words[i].charAt(0))).append(
                words[i].substring(1));   
    }  
    System.out.println(result);  

Output: Java Is An Object Oriented Programming Language.

From the openssl.pc file

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: OpenSSL
Description: Secure Sockets Layer and cryptography libraries and tools
Version: 0.9.8g
Requires:
Libs: -L${libdir} -lssl -lcrypto
Libs.private: -ldl -Wl,-Bsymbolic-functions -lz
Cflags: -I${includedir}

You can note the Include directory path and the Libs path from this. Now your prefix for the include files is /home/username/Programming . Hence your include file option should be -I//home/username/Programming.

(Yes i got it from the comments above)

This is just to remove logs regarding the headers. You may as well provide -L<Lib path> option for linking with the -lcrypto library.

I was able to reproduce this error when I was using webpack to build my javascript with the following chunk in my webpack.config.json:

externals: {
    'react': 'React'
},

This above configuration tells webpack to not resolve require('react') by loading an npm module, but instead to expect a global variable (i.e. on the window object) called React. The solution is to either remove this piece of configuration (so React will be bundled with your javascript) or load the React framework externally before this file is executed (so that window.React exists).

You can also use a jQuery plugin to do that

jQuery PrintPage plugin

Include js files of datepicker and language (locales)

'resource/bower_components/bootstrap-datepicker/dist/js/bootstrap-datepicker.min.js',
'resource/bower_components/bootstrap-datepicker/dist/locales/bootstrap-datepicker.sv.min.js',

In the options of the datepicker, set the language as below:

$('.datepicker').datepicker({'language' : 'sv'});

As you are using SQL Server 2008, go with Martin's answer.

If you find yourself needing to do it in SQL Server 2005 where you don't have access to the Date column type, I'd use:

SELECT DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()), 0)

You can have many java versions in your system.

I think you should add the java 8 in yours JREs installed or edit.

Take a look my screen:

If you click in edit (check your java 8 path):

Remove if from if @item.rigged ? "Yes" : "No"

Ternary operator has form condition ? if_true : if_false

What I can quickly think of is, generate the pdf and store it in webapp/downloads/< RANDOM-FILENAME>.pdf from the code and send a forward to this file using HttpServletRequest

request.getRequestDispatcher("/downloads/<RANDOM-FILENAME>.pdf").forward(request, response);

or if you can configure your view resolver something like,

  <bean id="pdfViewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="viewClass"
              value="org.springframework.web.servlet.view.JstlView" />
    <property name="order" value=”2"/>
    <property name="prefix" value="/downloads/" />
    <property name="suffix" value=".pdf" />
  </bean>

then just return

return "RANDOM-FILENAME";

Based on a general research and understanding, "Almost" Everything that can be accessed via a browser is actually called a "Web application" now these days. Even your internet router at home is a web application that uses the HTTP protocol to access the application (i.e the one that "interacts" with you). Yes, there are lots of websites that do "Nothing" except showing you stuff. But the age we are living in, everything operates on the basis of web application. Natwest PLC bank has got a website where you can go and find out things that natwest offer as a consumer/high-street bank. However:

1) You can create your online banking account - Web application 2) View, amend details on your personal stuff - web application 3) Manage money - Web application 4) Deal shares/stocks - Web application

Another good example is Fidelity.com (as quoted in many other examples on the web).

I'm going to have to argue and say that there are two answers:

1) If your purpose is simply to inform your audience with some contents that will never demand any interaction whatsoever, website is your answer. Then it is not a web application.

2) If you are living in the current/modern world i.e. will have a personal site, allow people to see some/all/none of your special stuff, protect yourself from people/bots/etc., web application and websites are no different.

To understand the difference between a scripting language and a programming language, one has to understand why scripting languages were born.

Initially, there were programming languages that was written to build programs like excel, word, browsers, games and etc. These programs were built with languages like c and java. Overtime, these programs needed a way for users to create new functionality, so they had to provide an interface to their bytecode and hence scripting languages were born.

A scripting language usually isnt compiled so can run as soon as you write something meaningful. Hence excel may be built using C++ but it exposes a scripting language called VBA for users to define functionality. Similarly browsers may be built with C++/Java but they expose a scripting language called javascript (not related to java in any way). Games, are usually built with C++ but expose a language called Lua for users to define custom functionality.

A scripting language usually sits behind some programming language. Scripting languages usually have less access to the computers native abilities since they run on a subset of the original programming language. An example here is that Javascript will not be able to access your file system. Scripting languages are usually slower than programming languages.

Although scripting languages may have less access and are slower, they can be very powerful tools. One factor attributing to a scripting languages success is the ease of updating. Do you remember the days of java applets on the web, this is an example of running a programming language (java) vs running a scripting language (javascript). At the time, computers were not as powerful and javascript wasn't as mature so Java applets dominated the scenes. But Java applets were annoying, they required the user to sort of load and compile the language. Fast forward to today, Java applets are almost extinct and Javascript dominates the scene. Javascript is extremely fast to load since most of the browser components have been installed already.

Lastly, scripting languages are also considered programming languages (although some people refuse to accept this) - the term we should be using here is scripting languages vs compiled languages.

It depends on your situation.

I would say, if your bool has a good name, then:

if (control.IsEnabled)  // Read "If control is enabled."
{
}

would be preferred.

If, however, the variable has a not-so-obvious name, checking against true would be helpful in understanding the logic.

if (first == true)  // Read "If first is true."
{
}

TextWatcher maritalStatusTextWatcher = new TextWatcher() { @Override public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

    }

    @Override
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
        try {
            if (charSequence.length()==0){
                topMaritalStatus.setVisibility(View.GONE);
            }else{
                topMaritalStatus.setVisibility(View.VISIBLE);
            }
        }catch (Exception e){
            e.printStackTrace();
        }
    }

    @Override
    public void afterTextChanged(Editable editable) {

    }
};

Just coerce the StatusCode to int.

var statusNumber;
try {
   response = (HttpWebResponse)request.GetResponse();
   // This will have statii from 200 to 30x
   statusNumber = (int)response.StatusCode;
}
catch (WebException we) {
    // Statii 400 to 50x will be here
    statusNumber = (int)we.Response.StatusCode;
}

Don't know why people are using so complex methods to achieve such a simple thing! And regex? Wow!

Here you go, the easiest and simplest way (as explained here: https://nabtron.com/kiss-code/ ):

$a = '000000000000001';
$a += 0;

echo $a; // will output 1

=if([Logical Test 1],[Action 1],if([Logical Test 2],[Action 1],if([Logical Test 3],[Action 3],[Value if all logical tests return false])))

Replace the components in the square brackets as necessary.

If you are using terminal just type the following:

locate my.cnf

Run this command :

    sudo chown -R yourUser /home/yourUser/.composer

This little program should be the solution ;-)

I hope this helps everyone.
