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

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

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

Read more about PDFKit in the Apple Developer documentation.

An improved version of @Thomas K's answer:

• Defining an assistant function is_any_thread_alive() according to this gist, which can terminates the main() automatically.

Example codes:

import threading

def job1():
    ...

def job2():
    ...

def is_any_thread_alive(threads):
    return True in [t.is_alive() for t in threads]

if __name__ == "__main__":
    ...
    t1 = threading.Thread(target=job1,daemon=True)
    t2 = threading.Thread(target=job2,daemon=True)
    t1.start()
    t2.start()

    while is_any_thread_alive([t1,t2]):
        time.sleep(0)

        $(document).ready(function () {
            $("#form-dialog").dialog({
                autoOpen: true,
                modal: true,
                width: 200,
                draggable: true,
                resizable: true,
                buttons: {
                    "Close": function () {
                        $("#idDialog").dialog("close");
                    }
                }
            });
        });

This will make you a button to close. you can also call the function close

$("#idDialog").dialog("close");

in some function to do this. or even in a button/a

< a href="javascript:void(0);" id="btnDone"   
                              onClick="$("#idDialog").dialog("close");">CLOSE</a>

EDIT: you need this to include your dialog into form:

open: function (type, data) {
            $(this).parent().appendTo($("form:first"));
        }

GZIP + Base64

The length of the string in a Base64 format is greater then original: 133% on average. So it makes sense to first compress it with GZIP, and then encode to Base64. It gives a reduction of up to 77% for strings greater than 200 characters and more. Example:

public static void main(String[] args) throws IOException {
    byte[] original = randomString(100).getBytes(StandardCharsets.UTF_8);

    byte[] base64 = encodeToBase64(original);
    byte[] gzipToBase64 = encodeToBase64(encodeToGZIP(original));

    byte[] fromBase64 = decodeFromBase64(base64);
    byte[] fromBase64Gzip = decodeFromGZIP(decodeFromBase64(gzipToBase64));

    // test
    System.out.println("Original: " + original.length + " bytes, 100%");
    System.out.println("Base64: " + base64.length + " bytes, "
            + (base64.length * 100 / original.length) + "%");
    System.out.println("GZIP+Base64: " + gzipToBase64.length + " bytes, "
            + (gzipToBase64.length * 100 / original.length) + "%");

    //Original: 3700 bytes, 100%
    //Base64: 4936 bytes, 133%
    //GZIP+Base64: 2868 bytes, 77%

    System.out.println(Arrays.equals(original, fromBase64)); // true
    System.out.println(Arrays.equals(original, fromBase64Gzip)); // true
}

public static byte[] decodeFromBase64(byte[] arr) {
    return Base64.getDecoder().decode(arr);
}

public static byte[] encodeToBase64(byte[] arr) {
    return Base64.getEncoder().encode(arr);
}

public static byte[] decodeFromGZIP(byte[] arr) throws IOException {
    ByteArrayInputStream bais = new ByteArrayInputStream(arr);
    GZIPInputStream gzip = new GZIPInputStream(bais);
    return gzip.readAllBytes();
}

public static byte[] encodeToGZIP(byte[] arr) throws IOException {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    GZIPOutputStream gzip = new GZIPOutputStream(baos);
    gzip.write(arr);
    gzip.finish();
    return baos.toByteArray();
}

public static String randomString(int count) {
    StringBuilder str = new StringBuilder();
    for (int i = 0; i < count; i++) {
        str.append(" ").append(UUID.randomUUID().toString());
    }
    return str.toString();
}

Another way of doing it would be:

stuff = Object.assign(stuff, {$(this).attr('value'):$(this).attr('checked')});

Used below code to set driver type based on need of Headless / Head for both Firefox and chrome:

// Can pass browser type 

if brower.lower() == 'chrome':
    driver = webdriver.Chrome('..\drivers\chromedriver')
elif brower.lower() == 'headless chrome':
    ch_Options = Options()
    ch_Options.add_argument('--headless')
    ch_Options.add_argument("--disable-gpu")
    driver = webdriver.Chrome('..\drivers\chromedriver',options=ch_Options)
elif brower.lower() == 'firefox':
    driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe')
elif brower.lower() == 'headless firefox':
    ff_option = FFOption()
    ff_option.add_argument('--headless')
    ff_option.add_argument("--disable-gpu")
    driver = webdriver.Firefox(executable_path=r'..\drivers\geckodriver.exe', options=ff_option)
elif brower.lower() == 'ie':
    driver = webdriver.Ie('..\drivers\IEDriverServer')
else:
    raise Exception('Invalid Browser Type')

This particular error is one annoying fact about v8. In most cases your JavaScript is broken in some way. For example missing a } or something like that.

Example given, this will yield "Unexpected end of input" too:

eval('[{"test": 4}') // notice the missing ]

But the root cause of the problems seems to be that the requested JSON url has a Content-Type of text/html which Chrome apparently tries to parse as HTML, which then results in the unexpected end of input due to the fact that the included image tags are being parsed.

Try setting the Content-Type to text/plain I think it should fix the issues.

Nonetheless, V8 could do a better Job about telling one exactly where the input ended unexpectedly.

SASS has a built-in rgba() function to evaluate values.

rgba($color, $alpha)

E.g.

rgba(#00aaff, 0.5) => rgba(0, 170, 255, 0.5)

An example using your own variables:

$my-color: #00aaff;
$my-opacity: 0.5;

.my-element {
  color: rgba($my-color, $my-opacity);
}

Outputs:

.my-element {
  color: rgba(0, 170, 255, 0.5);
}

Update: You can now remove an App ID (as noted by @Guru in the comments).

In the past, this was not possible: I had the same problem, and the folks at Apple replied that they will leave all of the App ID you create associated to your login, to keep track of a sort of history related to your login.

It seems that they finally changed idea about.

I can give you an example which results with the same problem, but it may not give you an answer to your question. (Additionally, in this example, I'm using my Maven 3 knowledge, which may not apply for Maven 2.)

In a multi-module maven project (contains modules A and B, where B depends on A), you can add also a test dependency on A from B.

This dependency may look as follows:

<dependency>
     <groupId>com.foo</groupId>
     <artifactId>A</artifactId>
     <type>test-jar</type> <!-- I'm not sure if there is such a thing in Maven 2, but there is definitely a way to achieve such dependency in Maven 2. -->
     <scope>test</scope>
</dependency>

(for more information refer to https://maven.apache.org/guides/mini/guide-attached-tests.html)
Note that the project A produces secondary artifact with a classifier tests where the test classes and test resources are located.

If you build your project with -Dmaven.test.skip=true, you will get a dependency resolution error as long as the test artifact wasn't found in your local repo or external repositories. The reason is that the tests classes were neither compiled nor the tests artifact was produced.
However, if you run your build with -DskipTests your tests artifact will be produced (though the tests won't run) and the dependency will be resolved.

Go to Solution properties ? Common Properties ? Startup Project and select Multiple startup projects.

There's an alternative to the StopIteration by using next(iterator, default_value).

For exapmle:

>>> a = iter('hi')
>>> print next(a, None)
h
>>> print next(a, None)
i
>>> print next(a, None)
None

So you can detect for None or other pre-specified value for end of the iterator if you don't want the exception way.

You could use COUNT(1) instead

I don't mention basics like syntax highlighting as I expect these by default.

This is a just dry list reflecting your feedback and comments, I am not advocating any of these tools. I will keep updating this list as you keep posting your answers.

PS. Can you help me to add features of the above editors to the list (like auto-complete, debugging, etc.)?

We have a comprehensive wiki page for this question https://wiki.python.org/moin/IntegratedDevelopmentEnvironments

The oracle limit is 1000 parameters. The issue has been resolved by hibernate in version 4.1.7 although by splitting the passed parameter list in sets of 500 see JIRA HHH-1123

This looks similar to How do I get github to default to ssh and not https for new repositories. Probably it's worth trying to switch from http protocol to ssh:

$ git remote add origin [email protected]:username/project.git

rm -rf ~/anaconda

It was pretty easy. It switched my pointer to Python: https://docs.continuum.io/anaconda/install#os-x-uninstall

Use Context.getDatabasePath(databasename). The context can be obtained from your application.

If you get previous data back it can be either a) the data was stored in an unconventional location and therefore not deleted with uninstall or b) Titanium backed up the data with the app (it can do that).

For iTunes 11 and above version:

open your iTunes "Side Bar" by going to View -> Show Side Bar drag the mobileprovision and ipa files to your iTunes "Apps" under LIBRARY Then click on your device. open you device Apps from DEVICES and click install for the application and wait for iTunes to sync

You need to use v-bind: or its alias :. For example,

<a v-bind:href="'/job/'+ r.id">

or

<a :href="'/job/' + r.id">

You can use the ThenBy and ThenByDescending extension methods:

foobarList.OrderBy(x => x.Foo).ThenBy( x => x.Bar)

If you are using maven, adding below dependency should work

<dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>

With pandas >= 1.0 there is now a dedicated string datatype:

1) You can convert your column to this pandas string datatype using .astype('string'):

df['zipcode'] = df['zipcode'].astype('string')

2) This is different from using str which sets the pandas object datatype:

df['zipcode'] = df['zipcode'].astype(str)

3) For changing into categorical datatype use:

df['zipcode'] = df['zipcode'].astype('category')

You can see this difference in datatypes when you look at the info of the dataframe:

df = pd.DataFrame({
    'zipcode_str': [90210, 90211] ,
    'zipcode_string': [90210, 90211],
    'zipcode_category': [90210, 90211],
})

df['zipcode_str'] = df['zipcode_str'].astype(str)
df['zipcode_string'] = df['zipcode_str'].astype('string')
df['zipcode_category'] = df['zipcode_category'].astype('category')

df.info()

# you can see that the first column has dtype object
# while the second column has the new dtype string
# the third column has dtype category
 #   Column            Non-Null Count  Dtype   
---  ------            --------------  -----   
 0   zipcode_str       2 non-null      object  
 1   zipcode_string    2 non-null      string  
 2   zipcode_category  2 non-null      category
dtypes: category(1), object(1), string(1)

The 'string' extension type solves several issues with object-dtype NumPy arrays:

1. You can accidentally store a mixture of strings and non-strings in an object dtype array. A StringArray can only store strings.

2. object dtype breaks dtype-specific operations like DataFrame.select_dtypes(). There isn’t a clear way to select just text while excluding non-text, but still object-dtype columns.

3. When reading code, the contents of an object dtype array is less clear than string.
   

More info on working with the new string datatype can be found here: https://pandas.pydata.org/pandas-docs/stable/user_guide/text.html

innerText is the current correct answer for this. The other answers are outdated and incorrect.

document.getElementById('ShowButton').innerText = 'Show filter';

innerHTML also works, and can be used to insert HTML.

First, add a textView in the XML file

<TextView  
    android:id="@+id/rate_id"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/what_U_want_to_display_in_first_time"
    />

then add a button in xml file with id btn_change_textView and write this two line of code in onCreate() method of activity

Button btn= (Button) findViewById(R.id. btn_change_textView);
TextView textView=(TextView)findViewById(R.id.rate_id);

then use clickListener() on button object like this

btn.setOnClickListener(new View.OnClickListener {
    public void onClick(View v) {
      
        textView.setText("write here what u want to display after button click in string");
    }
});

SWT by itself is pretty low-level, and it uses the platform's native widgets through JNI. It is not related to Swing and AWT at all. The Eclipse IDE and all Eclipse-based Rich Client Applications, like the Vuze BitTorrent client, are built using SWT. Also, if you are developing Eclipse plugins, you will typically use SWT.
I have been developing Eclipse-based applications and plugins for almost 5 years now, so I'm clearly biased. However, I also have extensive experience in working with SWT and the JFace UI toolkit, which is built on top of it. I have found JFace to be very rich and powerful; in some cases it might even be the main reason for choosing SWT. It enables you to whip up a working UI quite quickly, as long as it is IDE-like (with tables, trees, native controls, etc). Of course you can integrate your custom controls as well, but that takes some extra effort.

This is the core idiom for reference-counted objects.

Reference-counting is a strong form of deterministic garbage collection- it ensures objects manage their OWN lifetime instead of relying on 'smart' pointers, etc. to do it for them. The underlying object is only ever accessed via "Reference" smart pointers, designed so that the pointers increment and decrement a member integer (the reference count) in the actual object.

When the last reference drops off the stack or is deleted, the reference count will go to zero. Your object's default behavior will then be a call to "delete this" to garbage collect- the libraries I write provide a protected virtual "CountIsZero" call in the base class so that you can override this behavior for things like caching.

The key to making this safe is not allowing users access to the CONSTRUCTOR of the object in question (make it protected), but instead making them call some static member- the FACTORY- like "static Reference CreateT(...)". That way you KNOW for sure that they're always built with ordinary "new" and that no raw pointer is ever available, so "delete this" won't ever blow up.

Remove last 3 characters of a string

var str = '1437203995000';
str = str.substring(0, str.length-3);
// '1437203995'

Remove last 3 digits of a number

var a = 1437203995000;
a = (a-(a%1000))/1000;
// a = 1437203995

There are many answers that provide removing the last commit. However, here is asked how to remove specific commits, and in this case it is to remove the last three commits, to go back to commit on November 3.

You can do this with rebase. Simply do:

git rebase -i HEAD~4

This will list your last four commits.

Now you have the option to remove commits. You do that with drop text.

• Simply hit i on your keyboard and next to commits you want to remove write drop instead of default pick

• On the keyboard, hit exit and :wq

To make sure that commits are removed, write:

git log

You will see that commits you saved as drop are removed.

To push those changes to your remote branch, write:

git push --force

the simple way I believe is to import it then export it, using the certificate manager in Windows Management Console.

Make sure your JSON file does not have any trailing characters before or after. Maybe an unprintable one? You may want to try this way:

[{"english":"bag","kana":"kaban","kanji":"K"},{"english":"glasses","kana":"megane","kanji":"M"}]

The commons-lang library has a constant field available called SystemUtils.LINE_SEPARATOR

You actually can't manually "free" memory in C, in the sense that the memory is released from the process back to the OS ... when you call malloc(), the underlying libc-runtime will request from the OS a memory region. On Linux, this may be done though a relatively "heavy" call like mmap(). Once this memory region is mapped to your program, there is a linked-list setup called the "free store" that manages this allocated memory region. When you call malloc(), it quickly looks though the free-store for a free block of memory at the size requested. It then adjusts the linked list to reflect that there has been a chunk of memory taken out of the originally allocated memory pool. When you call free() the memory block is placed back in the free-store as a linked-list node that indicates its an available chunk of memory.

If you request more memory than what is located in the free-store, the libc-runtime will again request more memory from the OS up to the limit of the OS's ability to allocate memory for running processes. When you free memory though, it's not returned back to the OS ... it's typically recycled back into the free-store where it can be used again by another call to malloc(). Thus, if you make a lot of calls to malloc() and free() with varying memory size requests, it could, in theory, cause a condition called "memory fragmentation", where there is enough space in the free-store to allocate your requested memory block, but not enough contiguous space for the size of the block you've requested. Thus the call to malloc() fails, and you're effectively "out-of-memory" even though there may be plenty of memory available as a total amount of bytes in the free-store.

Changing Command Execute Timeout in Management Studio:

Click on Tools -> Options

Select Query Execution from tree on left side and enter command timeout in "Execute Timeout" control.

Changing Command Timeout in Server:

In the object browser tree right click on the server which give you timeout and select "Properties" from context menu.

Now in "Server Properties -....." dialog click on "Connections" page in "Select a Page" list (on left side). On the right side you will get property

Remote query timeout (in seconds, 0 = no timeout):
[up/down control]

you can set the value in up/down control.

def method_a(sample_string):
    binary = ' '.join(format(ord(x), 'b') for x in sample_string)

def method_b(sample_string):
    binary = ' '.join(map(bin,bytearray(sample_string,encoding='utf-8')))


if __name__ == '__main__':

    from timeit import timeit

    sample_string = 'Convert this ascii strong to binary.'

    print(
        timeit(f'method_a("{sample_string}")',setup='from __main__ import method_a'),
        timeit(f'method_b("{sample_string}")',setup='from __main__ import method_b')
    )

# 9.564299999998184 2.943955828988692

method_b is substantially more efficient at converting to a byte array because it makes low level function calls instead of manually transforming every character to an integer, and then converting that integer into its binary value.

You want:

dir > a.txt 2>&1

The syntax 2>&1 will redirect 2 (stderr) to 1 (stdout). You can also hide messages by redirecting to NUL, more explanation and examples on MSDN.

List is Doubly Linked List so it is easy to insert and delete an element. We have to just change the few pointers, whereas in vector if we want to insert an element in the middle then each element after it has to shift by one index. Also if the size of the vector is full then it has to first increase its size. So it is an expensive operation. So wherever insertion and deletion operations are required to be performed more often in such a case list should be used.

In the context of JWTs, Stormpath have written a fairly helpful article outlining possible ways to store them, and the (dis-)advantages pertaining to each method.

It also has a short overview of XSS and CSRF attacks, and how you can combat them.

I've attached some short snippets of the article below, in case their article is taken offline/their site goes down.

Local Storage

Problems:

Web Storage (localStorage/sessionStorage) is accessible through JavaScript on the same domain. This means that any JavaScript running on your site will have access to web storage, and because of this can be vulnerable to cross-site scripting (XSS) attacks. XSS in a nutshell is a type of vulnerability where an attacker can inject JavaScript that will run on your page. Basic XSS attacks attempt to inject JavaScript through form inputs, where the attacker puts alert('You are Hacked'); into a form to see if it is run by the browser and can be viewed by other users.

Prevention:

To prevent XSS, the common response is to escape and encode all untrusted data. But this is far from the full story. In 2015, modern web apps use JavaScript hosted on CDNs or outside infrastructure. Modern web apps include 3rd party JavaScript libraries for A/B testing, funnel/market analysis, and ads. We use package managers like Bower to import other peoples’ code into our apps.

What if only one of the scripts you use is compromised? Malicious JavaScript can be embedded on the page, and Web Storage is compromised. These types of XSS attacks can get everyone’s Web Storage that visits your site, without their knowledge. This is probably why a bunch of organizations advise not to store anything of value or trust any information in web storage. This includes session identifiers and tokens.

As a storage mechanism, Web Storage does not enforce any secure standards during transfer. Whoever reads Web Storage and uses it must do their due diligence to ensure they always send the JWT over HTTPS and never HTTP.

Cookies

Problems:

Cookies, when used with the HttpOnly cookie flag, are not accessible through JavaScript, and are immune to XSS. You can also set the Secure cookie flag to guarantee the cookie is only sent over HTTPS. This is one of the main reasons that cookies have been leveraged in the past to store tokens or session data. Modern developers are hesitant to use cookies because they traditionally required state to be stored on the server, thus breaking RESTful best practices. Cookies as a storage mechanism do not require state to be stored on the server if you are storing a JWT in the cookie. This is because the JWT encapsulates everything the server needs to serve the request.

However, cookies are vulnerable to a different type of attack: cross-site request forgery (CSRF). A CSRF attack is a type of attack that occurs when a malicious web site, email, or blog causes a user’s web browser to perform an unwanted action on a trusted site on which the user is currently authenticated. This is an exploit of how the browser handles cookies. A cookie can only be sent to the domains in which it is allowed. By default, this is the domain that originally set the cookie. The cookie will be sent for a request regardless of whether you are on galaxies.com or hahagonnahackyou.com.

Prevention:

Modern browsers support the SameSite flag, in addition to HttpOnly and Secure. The purpose of this flag is to prevent the cookie from being transmitted in cross-site requests, preventing many kinds of CSRF attack.

For browsers that do not support SameSite, CSRF can be prevented by using synchronized token patterns. This sounds complicated, but all modern web frameworks have support for this.

For example, AngularJS has a solution to validate that the cookie is accessible by only your domain. Straight from AngularJS docs:

When performing XHR requests, the $http service reads a token from a cookie (by default, XSRF-TOKEN) and sets it as an HTTP header (X-XSRF-TOKEN). Since only JavaScript that runs on your domain can read the cookie, your server can be assured that the XHR came from JavaScript running on your domain. You can make this CSRF protection stateless by including a xsrfToken JWT claim:

{
  "iss": "http://galaxies.com",
  "exp": 1300819380,
  "scopes": ["explorer", "solar-harvester", "seller"],
  "sub": "[email protected]",
  "xsrfToken": "d9b9714c-7ac0-42e0-8696-2dae95dbc33e"
}

Leveraging your web app framework’s CSRF protection makes cookies rock solid for storing a JWT. CSRF can also be partially prevented by checking the HTTP Referer and Origin header from your API. CSRF attacks will have Referer and Origin headers that are unrelated to your application.

The full article can be found here: https://stormpath.com/blog/where-to-store-your-jwts-cookies-vs-html5-web-storage/

They also have a helpful article on how to best design and implement JWTs, with regards to the structure of the token itself: https://stormpath.com/blog/jwt-the-right-way/

If the files are written using ES6 export, you can write:

module.exports = {
  ...require('./foo'),
  ...require('./bar'),
};

Try this, which I think makes it clear. the underlying array is changed but our slice is not, print just prints len() chars, by another slice to the cap(), you can see the changed array:

func main() {

  for i := 0; i < 7; i++ {
      a[i] = i
  }

  Test(a)

  fmt.Println(a) // prints [0..6]
  fmt.Println(a[:cap(a)] // prints [0..6,100]
}

Commands:

1. To start the kafka:

   $ nohup ~/kafka/bin/kafka-server-start.sh ~/kafka/config/server.properties > ~/kafka/kafka.log 2>&1 &

2. To list out all the topic on on kafka;

   $ bin/kafka-topics.sh --list --zookeeper localhost:2181

3. To check the data is landing on kafka topic and to print it out;

   $ bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic your_topic_name --from-beginning

I had the same problem, and in my case, the solution was updating the usb-serial driver using windows update on windows 10 device's manager. There was no need to download a especific driver, I just let windows update find a suitable driver.

If you are using Spring, you can force validation by annotating the class with @Validated:

import org.springframework.validation.annotation.Validated;

More info available here: Javax validation @NotNull annotation usage

My solution: String str = String.format ("%.0f", yourDouble);

Have you tried ALTER SYSTEM KILL SESSION? Get the SID and SERIAL# from V$SESSION for each session in the given schema, then do

ALTER SCHEMA KILL SESSION sid,serial#;

In the CMakeLists.txt file, create a cache variable, as documented here:

SET(FAB "po" CACHE STRING "Some user-specified option")

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#command:set

Then, either use the GUI (ccmake or cmake-gui) to set the cache variable, or specify the value of the variable on the cmake command line:

cmake -DFAB:STRING=po

Source: http://cmake.org/cmake/help/v2.8.8/cmake.html#opt:-Dvar:typevalue

Modify your cache variable to a boolean if, in fact, your option is boolean.

For me it was very important to get email logging working. After some time I discover that this need only 2 lines of code more in Atif example.

public class HandleErrorWithElmahAttribute : HandleErrorAttribute
{
    static ElmahMVCMailModule error_mail_log = new ElmahMVCMailModule();

    public override void OnException(ExceptionContext context)
    {
        error_mail_log.Init(HttpContext.Current.ApplicationInstance);
        [...]
    }
    [...]
}

I hope this will help someone :)

CSS Transforms Module Level 1 - Terminology - Transformable Element

A transformable element is an element in one of these categories:

• an element whose layout is governed by the CSS box model which is either a block-level or atomic inline-level element, or whose display property computes to table-row, table-row-group, table-header-group, table-footer-group, table-cell, or table-caption
• an element in the SVG namespace and not governed by the CSS box model which has the attributes transform, ‘patternTransform‘ or gradientTransform.

In your case, the <a> elements are inline by default.

Changing the display property's value to inline-block renders the elements as atomic inline-level elements, and therefore the elements become "transformable" by definition.

li a {
   display: inline-block;
   -webkit-transform: rotate(10deg);
   -moz-transform: rotate(10deg);
   -o-transform: rotate(10deg); 
   transform: rotate(10deg);
}

As mentioned above, this only seems to applicable in -webkit based browsers since it appears to work in IE/FF regardless.

using JSON.stringify(yourObj) or Object.toJSON(yourObj) last one is for using prototype.js, then send it using whatever you want, ajax or submit, and you use, as suggested, json_decode ( http://www.php.net/manual/en/function.json-decode.php ) to parse it in php. And then you can use it as an array.

INSERT INTO `dbMyDataBase`.`tblMyTable` 
(
    `IdAutoincrement`, 
    `Column2`, 
    `Column3`, 
    `Column4`

    NULL,  
    `Column2`, 
    `Column3`, 
    'CustomValue' AS Column4 
FROM `dbMyDataBase`.`tblMyTable` 
WHERE `tblMyTable`.`Column2` = 'UniqueValueOfTheKey'

This is my customized factory providing a customized names for thread dump analyzers. Usually I just give tf=null to reuse JVM default thread factory. This website has more advanced thread factory.

public class SimpleThreadFactory implements ThreadFactory {
    private ThreadFactory tf;
    private String nameSuffix;

    public SimpleThreadFactory (ThreadFactory tf, String nameSuffix) {
        this.tf = tf!=null ? tf : Executors.defaultThreadFactory();
        this.nameSuffix = nameSuffix; 
    }

    @Override public Thread newThread(Runnable task) {
        // default "pool-1-thread-1" to "pool-1-thread-1-myapp-MagicTask"
        Thread thread=tf.newThread(task);
        thread.setName(thread.getName()+"-"+nameSuffix);
        return thread;
    }
}

- - - - - 

ExecutorService es = Executors.newFixedThreadPool(4, new SimpleThreadFactory(null, "myapp-MagicTask") );

For your convenience this is a thread dump loop for debug purpose.

    ThreadMXBean mxBean=ManagementFactory.getThreadMXBean();
    long[] tids = mxBean.getAllThreadIds();
    System.out.println("------------");
    System.out.println("ThreadCount="+tids.length);
    for(long tid : tids) {
        ThreadInfo mxInfo=mxBean.getThreadInfo(tid);
        if (mxInfo==null) {
            System.out.printf("%d %s\n", tid, "Thread not found");
        } else {
            System.out.printf("%d %s, state=%s, suspended=%d, lockowner=%d %s\n"
                    , mxInfo.getThreadId(), mxInfo.getThreadName()
                    , mxInfo.getThreadState().toString()
                    , mxInfo.isSuspended()?1:0
                    , mxInfo.getLockOwnerId(), mxInfo.getLockOwnerName()
            );
        }
    }

Try like this: select DATENAME(DW,GETDATE())

DECIMAL(18,0) will allow 0 digits after the decimal point.

Use something like DECIMAL(18,4) instead that should do just fine!

That gives you a total of 18 digits, 4 of which after the decimal point (and 14 before the decimal point).

$dataProvider = new ActiveDataProvider([ 
    'query' => $query, 
    'sort'=> ['defaultOrder' => ['iUserId'=>SORT_ASC]] 
]);

A bit long winded but it works for me: try this::

=SUM(IF(OR(ISBLANK(AU2), NOT(ISERR(YEAR(AU2)))),0,1)
 +IF(OR(ISBLANK(AV2), NOT(ISERR(YEAR(AV2)))),0,1))

first part of if will allow cell to be blank or if there is something in the cell it tries to convert to a year, if there is an error or there is something other than a date result = 1, do the same for each cell and sum the result

am assuming custom_class to be your class to override heading color of the panel. just add !important to it or add inline styles or a id and add styles as they will have more specificity over class added styles.

• with !important

  .custom_class{ background-color: red !important; }

• with !important

• with ID :

  #custom_id{ background-color: red; }

-with inline styles :

<div id="custom_id" class="panel panel-default">
      <div class="panel-heading custom_class" style="background-color:red">
      </div>
    </div>

As it is written before, some folders (/META-INF/resources/, /resources/, /static/, /public/) serve static content by default, conroller misconfiguration can break this behaviour.

It is a common pitfall that people define the base url of a controller in the @RestController annotation, instead of the @RequestMapping annotation on the top of the controllers.

This is wrong:

@RestController("/api/base")
public class MyController {

    @PostMapping
    public String myPostMethod( ...) {

The above example will prevent you from opening the index.html. The Spring expects a POST method at the root, because the myPostMethod is mapped to the "/" path.

You have to use this instead:

@RestController
@RequestMapping("/api/base")
public class MyController {

    @PostMapping
    public String myPostMethod( ...) {

You must set proxy server for gradle at some time, you can try to change the proxy server ip address in gradle.properties which is under .gradle document

Use the PasteSpecial method:

sht.Columns("A:G").Copy
Range("A1").PasteSpecial Paste:=xlPasteValues

BUT your big problem is that you're changing your ActiveSheet to "Data" and not changing it back. You don't need to do the Activate and Select, as per my code (this assumes your button is on the sheet you want to copy to).

Webservices require unique namespaces so they don't confuse each others schemas and whatever with each other. A URL (domain, subdomain, subsubdomain, etc) is a clever identifier as it's "guaranteed" to be unique, and in most circumstances you've already got one.

You can't with inline styling alone. Do not recommend reimplementing CSS features in JavaScript we already have a language that is extremely powerful and incredibly fast built for this use case -- CSS. So use it! Made Style It to assist.

    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);

    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {

        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

You may have forgotten to define the Content-Type header. For example:

  return {
    statusCode: 200,
    headers: {
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ items }),
  }

The idea is to have equal size of message being sent from Kafka Producer to Kafka Broker and then received by Kafka Consumer i.e.

Kafka producer --> Kafka Broker --> Kafka Consumer

Suppose if the requirement is to send 15MB of message, then the Producer, the Broker and the Consumer, all three, needs to be in sync.

Kafka Producer sends 15 MB --> Kafka Broker Allows/Stores 15 MB --> Kafka Consumer receives 15 MB

The setting therefore should be:

a) on Broker:

message.max.bytes=15728640 
replica.fetch.max.bytes=15728640

b) on Consumer:

fetch.message.max.bytes=15728640

you have to set cellpadding and cellspacing that's it.

<table cellpadding="5" cellspacing="5">
<tr> 
<td>One</td> 
<td>Two</td> 
<td>Three</td> 
<td>Four</td> 
</tr>
</table>

Or just :

var a:Int = 3
var b:Int = 3
println(pow(Double(a),Double(b)))

Bandwidth is tiered by instance size, here's a comprehensive answer:

For t2/m3/c3/c4/r3/i2/d2 instances:

• t2.nano = ??? (Based on the scaling factors, I'd expect 20-30 MBit/s)
• t2.micro = ~70 MBit/s (qiita says 63 MBit/s) - t1.micro gets about ~100 Mbit/s
• t2.small = ~125 MBit/s (t2, qiita says 127 MBit/s, cloudharmony says 125 Mbit/s with spikes to 200+ Mbit/s)
• *.medium = t2.medium gets 250-300 MBit/s, m3.medium ~400 MBit/s
• *.large = ~450-600 MBit/s (the most variation, see below)
• *.xlarge = 700-900 MBit/s
• *.2xlarge = ~1 GBit/s +- 10%
• *.4xlarge = ~2 GBit/s +- 10%
• *.8xlarge and marked specialty = 10 Gbit, expect ~8.5 GBit/s, requires enhanced networking & VPC for full throughput

m1 small, medium, and large instances tend to perform higher than expected. c1.medium is another freak, at 800 MBit/s.

I gathered this by combing dozens of sources doing benchmarks (primarily using iPerf & TCP connections). Credit to CloudHarmony & flux7 in particular for many of the benchmarks (note that those two links go to google searches showing the numerous individual benchmarks).

Caveats & Notes:

The large instance size has the most variation reported:

• m1.large is ~800 Mbit/s (!!!)
• t2.large = ~500 MBit/s
• c3.large = ~500-570 Mbit/s (different results from different sources)
• c4.large = ~520 MBit/s (I've confirmed this independently, by the way)
• m3.large is better at ~700 MBit/s
• m4.large is ~445 Mbit/s
• r3.large is ~390 Mbit/s

Burstable (T2) instances appear to exhibit burstable networking performance too:

• The CloudHarmony iperf benchmarks show initial transfers start at 1 GBit/s and then gradually drop to the sustained levels above after a few minutes. PDF links to reports below:

• t2.small (PDF)

• t2.medium (PDF)
• t2.large (PDF)

Note that these are within the same region - if you're transferring across regions, real performance may be much slower. Even for the larger instances, I'm seeing numbers of a few hundred MBit/s.

add this to your div

white-space: nowrap;

http://jsfiddle.net/NXchy/1/

If you want dot/comma separated numbers also, then:

\d*\.?\d*

or

[0-9]*\.?[0-9]*

You can use https://regex101.com/ to test your regexes.

I'm having a hard time figuring out what exactly you're looking for here, so hope I'm not way off base.

I'm assuming what you mean is that when a keyup event occurs on the input with class "start" you want to get the values of all the inputs in neighbouring <td>s:

    $('.start').keyup(function() {
        var otherInputs = $(this).parents('td').siblings().find('input');

        for(var i = 0; i < otherInputs.length; i++) {
            alert($(otherInputs[i]).val());
        }
        return false;
    });

Start Task Manager, click on the Processes tab, right-click on wscript.exe and select End Process, and confirm in the dialog that follows. This will terminate the wscript.exe that is executing your script.

I found the error was shown due to the comments at the beginning of file , You can solve this issue , by simply creating your own file without comment and push to git, it shows no error

For proof you can try these two file with same code of easy pagination :

without comment

with comment

You can store them in tasks, then await them all:

var catTask = FeedCat();
var houseTask = SellHouse();
var carTask = BuyCar();

await Task.WhenAll(catTask, houseTask, carTask);

Cat cat = await catTask;
House house = await houseTask;
Car car = await carTask;

You should do a move of the file to rename it. In your example code you are only changing the string, not the file:

myfile= "c:/my documents/my images/cars/a.jpg";
string extension = Path.GetExtension(myffile); 
myfile.replace(extension,".Jpeg");

you are only changing myfile (which is a string). To move the actual file, you should do

FileInfo f = new FileInfo(myfile);
f.MoveTo(Path.ChangeExtension(myfile, ".Jpeg"));

See FileInfo.MoveTo

Following are few options available to change Heap Size.

-Xms<size>        set initial Java heap size
-Xmx<size>        set maximum Java heap size
-Xss<size>        set java thread stack size

java -Xmx256m TestData.java

As I recognize, at the moment, in JUnit, the syntax is like this:

AssertTrue(Long.parseLong(previousTokenValues[1]) > Long.parseLong(currentTokenValues[1]), "your fail message ");

Means that, the condition is in front of the message.

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

Try this:

preg_replace('/[^0-9]/', '', '604-619-5135');

preg_replace uses PCREs which generally start and end with a /.

In manually deleting a topic from a kafka cluster , you just might check this out https://github.com/darrenfu/bigdata/issues/6 A vital step missed a lot in most solution is in deleting the /config/topics/<topic_name> in ZK.

Before Mysql version 5.0.3 Varchar datatype can store 255 character, but from 5.0.3 it can be store 65,535 characters.

BUT it has a limitation of maximum row size of 65,535 bytes. It means including all columns it must not be more than 65,535 bytes.

In your case it may possible that when you are trying to set more than 10000 it is exceeding more than 65,535 and mysql will gives the error.

Updated 10-second countdown using class Clock extends Component

import React, { Component } from 'react';

class Clock extends Component {
  constructor(props){
    super(props);
    this.state = {currentCount: 10}
  }
  timer() {
    this.setState({
      currentCount: this.state.currentCount - 1
    })
    if(this.state.currentCount < 1) { 
      clearInterval(this.intervalId);
    }
  }
  componentDidMount() {
    this.intervalId = setInterval(this.timer.bind(this), 1000);
  }
  componentWillUnmount(){
    clearInterval(this.intervalId);
  }
  render() {
    return(
      <div>{this.state.currentCount}</div>
    );
  }
}

module.exports = Clock;

An HttpOnly cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly.

Just set it as such on the server side using whatever server side language the server side is using. If JavaScript is absolutely necessary for this, you could consider to just let it send some (ajax) request with e.g. some specific request parameter which triggers the server side language to create an HttpOnly cookie. But, that would still make it easy for hackers to change the HttpOnly by just XSS and still have access to the cookie via JS and thus make the HttpOnly on your cookie completely useless.

I prefer this:

public enum Color {

   White,

   Green,

   Blue,

   Purple,

   Orange,

   Red
}

then:

//cast enum to int
int color = Color.Blue.ordinal();

You should try with the parent elements;

html, body, form, main {
    height: 100%;
}

Then this will be enough :

#s7 {
   height: 100%;
}

Involve following steps to resolve the issue:

1) Install the CLI and env preset

$ npm install --save-dev babel-cli babel-preset-env

2) Create a .babelrc file

{
  "presets": ["env"]
}

3) configure npm start in package.json

"scripts": {
    "start": "babel-node ./server/app.js",
    "test": "echo \"Error: no test specified\" && exit 1"
  }

4) then start app

$ npm start

Let say you have an exchange call like below:

String url = "/zzz/{accountNumber}";

Optional<AccountResponse> accResponse = Optional.ofNullable(accountNumber)
        .map(account -> {


            HttpHeaders headers = new HttpHeaders();
            headers.setContentType(MediaType.APPLICATION_JSON);
            headers.set("Authorization", "bearer 121212");


            HttpEntity<Object> entity = new HttpEntity<>(headers);
            ResponseEntity<AccountResponse> response = template.exchange(
                    url,
                    GET,
                    entity,
                    AccountResponse.class,
                    accountNumber
            );

            return response.getBody();
        });

To mock this in your test case you can use mocitko as below:

when(restTemplate.exchange(
        ArgumentMatchers.anyString(),
        ArgumentMatchers.any(HttpMethod.class),
        ArgumentMatchers.any(),
        ArgumentMatchers.<Class<AccountResponse>>any(),
        ArgumentMatchers.<ParameterizedTypeReference<List<Object>>>any())
)

Yes unfortunately it will always load the full file. If you're doing this repeatedly probably best to extract the sheets to separate CSVs and then load separately. You can automate that process with d6tstack which also adds additional features like checking if all the columns are equal across all sheets or multiple Excel files.

import d6tstack
c = d6tstack.convert_xls.XLStoCSVMultiSheet('multisheet.xlsx')
c.convert_all() # ['multisheet-Sheet1.csv','multisheet-Sheet2.csv']

See d6tstack Excel examples

If copy assignment operator of foo and bar is cheap (eg. int, char, pointer etc), you can do the following:

foo f; bar b;
BOOST_FOREACH(boost::tie(f,b),testing)
{
  cout << "Foo is " << f << " Bar is " << b;
}

I sometimes use a bit of a trick to do just that. I put an invisible focus holder somewhere on the top of the layout. It would be e.g. like this

 <EditText android:id="@id/editInvisibleFocusHolder"
          style="@style/InvisibleFocusHolder"/>

with this style

<style name="InvisibleFocusHolder">
    <item name="android:layout_width">0dp</item>
    <item name="android:layout_height">0dp</item>
    <item name="android:focusable">true</item>
    <item name="android:focusableInTouchMode">true</item>
    <item name="android:inputType">none</item>
</style>

and then in onResume I would call

    editInvisibleFocusHolder.setInputType(InputType.TYPE_NULL);
    editInvisibleFocusHolder.requestFocus();

That works nicely for me from 1.6 up to 4.x

You cannot resize an array in java.

Once the size of array is declared, it remains fixed.

Instead you can use ArrayList that has dynamic size, meaning you don't need to worry about its size. If your array list is not big enough to accommodate new values then it will be resized automatically.

ArrayList<String> ar = new ArrayList<String>();
String s1 ="Test1";
String s2 ="Test2";
String s3 ="Test3";
ar.add(s1);
ar.add(s2);
ar.add(s3);

String s4 ="Test4";
ar.add(s4);

It's very important that the input field does not have display: none. The browser will not select the text and therefore will not be copied. Use opacity: 0 with a width of 0px to fix the problem.

I had huge difficulty getting this to work for a shell variable containing a filename with whitespace. For some reason using:

file="foo bar/baz"
scp [email protected]:"'$file'"

as in @Adrian's answer seems to fail.

Turns out that what works best is using a parameter expansion to prepend backslashes to the whitespace as follows:

file="foo bar/baz"
file=${file// /\\ }
scp [email protected]:"$file"

Here's what I ended up using.

I'm very new to AngularJS, so would love to see better / alternative solutions.

angular.module('formComponents', [])
    .directive('formInput', function() {
        return {
            restrict: 'E',
            scope: {},
            link: function(scope, element, attrs)
            {
                var type = attrs.type || 'text';
                var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
                var htmlText = '<div class="control-group">' +
                    '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                        '<div class="controls">' +
                        '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                        '</div>' +
                    '</div>';
                element.html(htmlText);
            }
        }
    })

Example usage:

<form-input label="Application Name" form-id="appName" required/></form-input>
<form-input type="email" label="Email address" form-id="emailAddress" required/></form-input>
<form-input type="password" label="Password" form-id="password" /></form-input>

\ does the job. @Guillaume's answer and @George's comment clearly answer this question. Here I explains why The backslash has to be the very last character before the end of line character. Consider this command:

   mysql -uroot \
   -hlocalhost      

If there is a space after \, the line continuation will not work. The reason is that \ removes the special meaning for the next character which is a space not the invisible line feed character. The line feed character is after the space not \ in this example.

I think both have their place. One issue with using @property is that it is hard to extend the behaviour of getters or setters in subclasses using standard class mechanisms. The problem is that the actual getter/setter functions are hidden in the property.

You can actually get hold of the functions, e.g. with

class C(object):
    _p = 1
    @property
    def p(self):
        return self._p
    @p.setter
    def p(self, val):
        self._p = val

you can access the getter and setter functions as C.p.fget and C.p.fset, but you can't easily use the normal method inheritance (e.g. super) facilities to extend them. After some digging into the intricacies of super, you can indeed use super in this way:

# Using super():
class D(C):
    # Cannot use super(D,D) here to define the property
    # since D is not yet defined in this scope.
    @property
    def p(self):
        return super(D,D).p.fget(self)

    @p.setter
    def p(self, val):
        print 'Implement extra functionality here for D'
        super(D,D).p.fset(self, val)

# Using a direct reference to C
class E(C):
    p = C.p

    @p.setter
    def p(self, val):
        print 'Implement extra functionality here for E'
        C.p.fset(self, val)

Using super() is, however, quite clunky, since the property has to be redefined, and you have to use the slightly counter-intuitive super(cls,cls) mechanism to get an unbound copy of p.

// create table
var dt = new System.Data.DataTable("tableName");

// create fields
dt.Columns.Add("field1", typeof(int));
dt.Columns.Add("field2", typeof(string));
dt.Columns.Add("field3", typeof(DateTime));

// insert row values
dt.Rows.Add(new Object[]{
                123456,
                "test",
                DateTime.Now
           });

I believe the answer is very simple and it has to do with semantic rules of references and how arrays are handled in C++.

In short: References can be thought of as structs which don't have a default constructor, so all the same rules apply.

1) Semantically, references don't have a default value. References can only be created by referencing something. References don't have a value to represent the absence of a reference.

2) When allocating an array of size X, program creates a collection of default-initialized objects. Since reference doesn't have a default value, creating such an array is semantically illegal.

This rule also applies to structs/classes which don't have a default constructor. The following code sample doesn't compile:

struct Object
{
    Object(int value) { }
};

Object objects[1]; // Error: no appropriate default constructor available

Use String#slice, also aliased as [].

a = "hello there"
a[1]                   #=> "e"
a[1,3]                 #=> "ell"
a[1..3]                #=> "ell"
a[6..-1]               #=> "there"
a[6..]                 #=> "there" (requires Ruby 2.6+)
a[-3,2]                #=> "er"
a[-4..-2]              #=> "her"
a[12..-1]              #=> nil
a[-2..-4]              #=> ""
a[/[aeiou](.)\1/]      #=> "ell"
a[/[aeiou](.)\1/, 0]   #=> "ell"
a[/[aeiou](.)\1/, 1]   #=> "l"
a[/[aeiou](.)\1/, 2]   #=> nil
a["lo"]                #=> "lo"
a["bye"]               #=> nil

I added this to Espuz and JCC's answer. It uses the y position of the subviews and doesn't include the scroll bars. Edit Uses the bottom of the lowest sub view that is visible.

+ (CGFloat) bottomOfLowestContent:(UIView*) view
{
    CGFloat lowestPoint = 0.0;

    BOOL restoreHorizontal = NO;
    BOOL restoreVertical = NO;

    if ([view respondsToSelector:@selector(setShowsHorizontalScrollIndicator:)] && [view respondsToSelector:@selector(setShowsVerticalScrollIndicator:)])
    {
        if ([(UIScrollView*)view showsHorizontalScrollIndicator])
        {
            restoreHorizontal = YES;
            [(UIScrollView*)view setShowsHorizontalScrollIndicator:NO];
        }
        if ([(UIScrollView*)view showsVerticalScrollIndicator])
        {
            restoreVertical = YES;
            [(UIScrollView*)view setShowsVerticalScrollIndicator:NO];
        }
    }
    for (UIView *subView in view.subviews)
    {
        if (!subView.hidden)
        {
            CGFloat maxY = CGRectGetMaxY(subView.frame);
            if (maxY > lowestPoint)
            {
                lowestPoint = maxY;
            }
        }
    }
    if ([view respondsToSelector:@selector(setShowsHorizontalScrollIndicator:)] && [view respondsToSelector:@selector(setShowsVerticalScrollIndicator:)])
    {
        if (restoreHorizontal)
        {
            [(UIScrollView*)view setShowsHorizontalScrollIndicator:YES];
        }
        if (restoreVertical)
        {
            [(UIScrollView*)view setShowsVerticalScrollIndicator:YES];
        }
    }

    return lowestPoint;
}

I am using Android Studio 3.3.

Go to View -> Tools Window -> Device File Explorer. Or you can find it on the Bottom Right corner of the Android Studio.

If the Emulator is running, the Device File Explorer will display the File structure on Emulator Storage.

Here you can right click on a Folder and select "Upload" to place the file

If you are binding like I was:

<%# Container.DataItem.GetType().GetProperty("Property1") != null ? DataBinder.Eval(Container.DataItem, "Property1") : DataBinder.Eval(Container.DataItem, "Property2")  %>

if you are using matplotlib version 3.1.1 or above, you can try:

import matplotlib.pyplot as plt
from matplotlib.colors import ListedColormap

x = [1, 3, 4, 6, 7, 9]
y = [0, 0, 5, 8, 8, 8]
classes = ['A', 'B', 'C']
values = [0, 0, 1, 2, 2, 2]
colours = ListedColormap(['r','b','g'])
scatter = plt.scatter(x, y,c=values, cmap=colours)
plt.legend(handles=scatter.legend_elements()[0], labels=classes)

swift 4 work as well as 3

libero.setTitle("---", for: .normal)

where libero is a uibutton

For me, this issue was proxy related. In Mac osx, even while above error is displayed, there is menu bar for Android Studio at top. Select preferences Android Studio -> Preferences and change proxy as below and issue was resolved. There could be similar options in Windows/Linux to access preferences page while error is being displayed.

You have already have container-selinux installed for version 3.7 check if the following docker-ce version works for you , it did for me.

sudo yum -y install docker-ce-cli.x86_64 1:19.03.5-3.el7

For upload:

An official list of mime types can be found at The Internet Assigned Numbers Authority (IANA) . According to their list Content-Type header for zip is application/zip.

The media type for rar files is not officially registered at IANA but the unofficial commonly used mime-type value is application/x-rar-compressed.

application/octet-stream means as much as: "I send you a file stream and the content of this stream is not specified" (so it is true that it can be a zip or rar file as well). The server is supposed to detect what the actual content of the stream is.

Note: For upload it is not safe to rely on the mime type set in the Content-Type header. The header is set on the client and can be set to any random value. Instead you can use the php file info functions to detect the file mime-type on the server.

For download:

If you want to download a zip file and nothing else you should only set one single Accept header value. Any additional values set will be used as a fallback in case the server cannot satisfy your in the Accept header requested mime-type.

According to the WC3 specifications this:

application/zip, application/octet-stream 

will be intrepreted as: "I prefer a application/zip mime-type, but if you cannot deliver this an application/octet-stream (a file stream) is also fine".

So only a single:

application/zip

Will guarantee you a zip file (or a 406 - Not Acceptable response in case the server is unable to satisfy your request).

I also face same issue after some search I found a good solution as @GreyBeardedGeek mentioned that setTimeout is the key of this solution.He is totally correct. In your method you just need to add setTimeout and your problem will be solved.

setTimeout(() => this.inputEl.nativeElement.focus(), 0);

Let me give some examples.

Consider this data.

CREATE TABLE DATASET ( VAL1 CHAR ( 1 CHAR ),
                   VAL2 VARCHAR2 ( 10 CHAR ),

You have N columns in select (excluding aggregations), then you should have N or N+x columns

Since you're getting the data pasted to clipboard, there is no reliable way of knowing the origin of the file and its properties (including name).

Your best bet is to come up with a file naming scheme of your own and send along with the blob.

form.append("filename",getFileName());
form.append("blob",blob);

function getFileName() {
 // logic to generate file names
}

This post was helpful, but just wanted to share a slight alternative that may help others:

Setting max-height instead of height also does the trick. In my case, I'm disabling scrolling based on a class toggle. Setting .someContainer {height: 100%; overflow: hidden;} when the container's height is smaller than that of the viewport would stretch the container, which wouldn't be what you'd want. Setting max-height accounts for this, but if the container's height is greater than the viewport's when the content changes, still disables scrolling.

Many answers are correct! I want to add that you can easily find your download location with

gradle --info build

like described in https://stackoverflow.com/a/54000767/4471199.

New downloaded artifacts will be shown in stdout:

Downloading https://plugins.gradle.org/m2/org/springframework/boot/spring-boot-parent/2.1.7.RELEASE/spring-boot-parent-2.1.7.RELEASE.pom to /tmp/gradle_download551283009937119777bin

In this case, I used the docker image gradle:5.6.2-jdk12. As you can see, the docker container uses /tmp as download location.

you need to use add class open in <div class="btn-group open">

and in li add class="active"

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

A simple way of catching thread's exception and communicating back to the caller method could be by passing dictionary or a list to worker method.

Example (passing dictionary to worker method):

import threading

def my_method(throw_me):
    raise Exception(throw_me)

def worker(shared_obj, *args, **kwargs):
    try:
        shared_obj['target'](*args, **kwargs)
    except Exception as err:
        shared_obj['err'] = err

shared_obj = {'err':'', 'target': my_method}
throw_me = "Test"

th = threading.Thread(target=worker, args=(shared_obj, throw_me), kwargs={})
th.start()
th.join()

if shared_obj['err']:
    print(">>%s" % shared_obj['err'])

Note that you can use the Polynomial class directly to do the fitting and return a Polynomial instance.

from numpy.polynomial import Polynomial

p = Polynomial.fit(x, y, 4)
plt.plot(*p.linspace())

p uses scaled and shifted x values for numerical stability. If you need the usual form of the coefficients, you will need to follow with

pnormal = p.convert(domain=(-1, 1))

I removed the previous Android SDK and Eclipse. I installed the ADT bundle and it works...

This fixed the problem of BufferOverflow on Dex that started after I got API 19. I was previously using Eclipse with Android SDK installed as an add-on package.

Try this Code

var app = angular.module('myapp', []);
  app.controller('testController', function ($scope, $http) {
       $scope.init = function(){           
       alert($scope.testInput);

The most straight-forward way I can think of is using numpy's gradient function:

x = numpy.linspace(0,10,1000)
dx = x[1]-x[0]
y = x**2 + 1
dydx = numpy.gradient(y, dx)

This way, dydx will be computed using central differences and will have the same length as y, unlike numpy.diff, which uses forward differences and will return (n-1) size vector.

As greg said you can embed HTML content in Markdown, but one of the points of Markdown is to avoid having to have extensive (or any, for that matter) CSS/HTML markup knowledge, right? This is what I do:

In my Markdown file I simply instruct all my wiki editors to embed wrap all images with something that looks like this:

'<div> // Put image here  </div>`

(of course.. they don't know what <div> means, but that shouldn't matter)

So the Markdown file looks like this:

<div>
![optional image description][1]
</div>

[1]: /image/path

And in the CSS content that wraps the whole page I can do whatever I want with the image tag:

img {
   float: right;
}

Of course you can do more with the CSS content... (in this particular case, wrapping the img tag with div prevents other text from wrapping against the image... this is just an example, though), but IMHO the point of Markdown is that you don't want potentially non-technical people getting into the ins and outs of CSS/HTML.. it's up to you as a web developer to make your CSS content that wraps the page as generic and clean as possible, but then again your editors need not know about that.

MySQL Utilities by Oracle have a command called mysqldiskusage that displays the disk usage of every database: https://dev.mysql.com/doc/mysql-utilities/1.6/en/mysqldiskusage.html

Further to @montrealmike 's answer, can I just add my adaptation?

I did this:

.container { 
  overflow: hidden; 
  .... 
} 

#sidebar { 
  margin-bottom: -101%;
  padding-bottom: 101%; 
  .... 
} 

I did the "101%" thing to cater for the (ultra rare) possibility that somebody may be viewing the site on a huge screen with a height more than 5000px!

Great answer though, montrealmike. It worked perfectly for me.

What is NOT so obvious is that you can use the following pattern to recursively search

./src/**/*.html

so perhaps leave the following as the default for most of your typical searches to remind that there is such a thing

./src/**/

For example I was after an attribute for left-right justify/docking content, I could not remember except "start" so I did the following search which reveals to me "item-start"

This fixed my layout to

Instead of

Here is where "item-sart" goes in the template.

Use this simple technique to do it :

Step 1 : CREATE A FRAGMENT DIALOG

public class DatePickerFragmentDialog  extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);

        return new DatePickerDialog(getActivity(), (DatePickerDialog.OnDateSetListener) getActivity(), year, month, day);
    }

}

Step 2 : IN REQUIRED ACTIVITY FOLLOW THIS

1. The activity must implement : DatePickerDialog.OnDateSetListener

2. Set onClickListener on a Button:

   DialogFragment datePicker = new DatePickerFragmentDialog();
   datePicker.show(getSupportFragmentManager(), "Custom Date Picker");
   

Step 3 : Override OnDateSetListener

public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.YEAR, year);
        calendar.set(Calendar.MONTH, month);
        calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

        @SuppressLint("SimpleDateFormat") DateFormat dateFormat = new 
        SimpleDateFormat("MM/dd/yyyy");
        String currentDateString = dateFormat.format(calendar.getTime());

        tvPaymentDate.setText(currentDateString);
    }

Therefore we can use any formatting for the date :)

Or you can do this:

MyString[0];

Below code worked for me without looking for any other Python libraries.

def count_repeated_letter(string1):
    list1=[]

    for letter in string1:
        if string1.count(letter)>=2:
            if letter not in list1:
                list1.append(letter)


    for item in list1:
        if item!= " ":
            print(item,string1.count(item))


count_repeated_letter('letter has 1 e and 2 e and 1 t and two t')

Output:

e 4
t 5
a 4
1 2
n 3
d 3

You can also check for socket output stream error while writing to client socket.

out.println(output);
if(out.checkError())
{
    throw new Exception("Error transmitting data.");
}

The best secure method is to use the crontab. ie Save all your commands in a database say, mysql table and create a cronjob to read these mysql entreis and execute via exec() or shell_exec(). Please read this link for more detailed information.

When it comes to casting to Enum type:

private static Enum GetEnum(Type type, int value)
    {
        if (type.IsEnum)
            if (Enum.IsDefined(type, value))
            {
                return (Enum)Enum.ToObject(type, value);
            }

        return null;
    }

And you will call it like that:

var enumValue = GetEnum(typeof(YourEnum), foo);

This was essential for me in case of getting Description attribute value of several enum types by int value:

public enum YourEnum
{
    [Description("Desc1")]
    Val1,
    [Description("Desc2")]
    Val2,
    Val3,
}

public static string GetDescriptionFromEnum(Enum value, bool inherit)
    {
        Type type = value.GetType();

        System.Reflection.MemberInfo[] memInfo = type.GetMember(value.ToString());

        if (memInfo.Length > 0)
        {
            object[] attrs = memInfo[0].GetCustomAttributes(typeof(DescriptionAttribute), inherit);
            if (attrs.Length > 0)
                return ((DescriptionAttribute)attrs[0]).Description;
        }

        return value.ToString();
    }

and then:

string description = GetDescriptionFromEnum(GetEnum(typeof(YourEnum), foo));
string description2 = GetDescriptionFromEnum(GetEnum(typeof(YourEnum2), foo2));
string description3 = GetDescriptionFromEnum(GetEnum(typeof(YourEnum3), foo3));

Alternatively (better approach), such casting could look like that:

 private static T GetEnum<T>(int v) where T : struct, IConvertible
    {
        if (typeof(T).IsEnum)
            if (Enum.IsDefined(typeof(T), v))
            {
                return (T)Enum.ToObject(typeof(T), v);
            }

        throw new ArgumentException(string.Format("{0} is not a valid value of {1}", v, typeof(T).Name));
    }

I known this isn't markdown, but <p align="center"> worked for me, so if anyone figures out the markdown syntax instead I'll be happy to use that. Until then I'll use the HTML tag.

• code inside your if(myVar) { code } will be NOT executed only when myVar is equal to: false, 0, "", null, undefined, NaN or you never defined variable myVar (then additionally code stop execution and throw exception).
• code inside your if(myVar !== null) {code} will be NOT executed only when myVar is equal to null or you never defined it (throws exception).

Here you have all (src)

=== (its negation !==)

You can check if the Google Play Store app is installed and, if this is the case, you can use the "market://" protocol.

final String my_package_name = "........."  // <- HERE YOUR PACKAGE NAME!!
String url = "";

try {
    //Check whether Google Play store is installed or not:
    this.getPackageManager().getPackageInfo("com.android.vending", 0);

    url = "market://details?id=" + my_package_name;
} catch ( final Exception e ) {
    url = "https://play.google.com/store/apps/details?id=" + my_package_name;
}


//Open the app page in Google Play store:
final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
startActivity(intent);

Both of the following code will work fine for removing highchart.com from the chart:-

credits: false

or

credits:{
 enabled:false,
}

Since 2.3.25, do it like this:

<#list user as propName, propValue>
  ${propName} = ${propValue}
</#list>

Note that this also works with non-string keys (unlike map[key], which had to be written as map?api.get(key) then).

Before 2.3.25 the standard solution was:

<#list user?keys as prop>
  ${prop} = ${user[prop]}
</#list>

However, some really old FreeMarker integrations use a strange configuration, where the public Map methods (like getClass) appear as keys. That happens as they are using a pure BeansWrapper (instead of DefaultObjectWrapper) whose simpleMapWrapper property was left on false. You should avoid such a setup, as it mixes the methods with real Map entries. But if you run into such unfortunate setup, the way to escape the situation is using the exposed Java methods, such as user.entrySet(), user.get(key), etc., and not using the template language constructs like ?keys or user[key].

There is no native way to do this in Javascript. You could use a library or write a small function to do this instead: http://ejohn.org/blog/javascript-array-remove/

use form shown event and set

MyTextBox.Focus();

It can also be done using backtracking by maintaining a visited array.

void foo(vector<vector<int> > &s,vector<int> &data,int go,int k,vector<int> &vis,int tot)
{

    vis[go]=1;
    data.push_back(go);
    if(data.size()==k)
    {
        s.push_back(data);
        vis[go]=0;
    data.pop_back();
        return;
    }

    for(int i=go+1;i<=tot;++i)
    {
       if(!vis[i])
       {
           foo(s,data,i,k,vis,tot);
       }
    }
    vis[go]=0;
    data.pop_back();
}


vector<vector<int> > Solution::combine(int n, int k) {
   vector<int> data;
   vector<int> vis(n+1,0);
   vector<vector<int> > sol;
   for(int i=1;i<=n;++i)
   {
       for(int i=1;i<=n;++i) vis[i]=0;
   foo(sol,data,i,k,vis,n);
   }
   return sol;

}

I came up with this, where n is the number of lines you want to delete:

count=`wc -l file`
lines=`expr "$count" - n`
head -n "$lines" file > temp.txt
mv temp.txt file
rm -f temp.txt

It's a little roundabout, but I think it's easy to follow.

1. Count up the number of lines in the main file
2. Subtract the number of lines you want to remove from the count
3. Print out the number of lines you want to keep and store in a temp file
4. Replace the main file with the temp file
5. Remove the temp file

Also, you can do this:

FirstClass.this.overridePendingTransition(android.R.anim.slide_in_left, android.R.anim.slide_out_right);

And you don't need to add any animation xml

You can concatenate Strings using the + operator:

String a="hello ";
String b="world.";
System.out.println(a+b);

Output:

hello world.

That's it

Hope this helps, with Serverless framework you can do something like this:

1. Add these things in your serverless.yml file:

plugins: - serverless-webpack custom: webpackIncludeModules: forceInclude: - <your package name> (for example: node-fetch) 2. Then create your Lambda function, deploy it by serverless deploy, the package that included in serverless.yml will be there for you.

For more information about serverless: https://serverless.com/framework/docs/providers/aws/guide/quick-start/

Yes, it is possible. The steps are:

1. First Put the .mdf and .ldf file in C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\ folder

2. Then go to sql software , Right-click “Databases” and click the “Attach” option to open the Attach Databases dialog box

3. Click the “Add” button to open and Locate Database Files From C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\folder

4. Click the "OK" button. SQL Server Management Studio loads the database from the .MDF file.

If you use rs.next() you will move the cursor, than you should to move first() why don't check using first() directly?

    public void fetchData(ResultSet res, JTable table) throws SQLException{     
    ResultSetMetaData metaData = res.getMetaData();
    int fieldsCount = metaData.getColumnCount();
    for (int i = 1; i <= fieldsCount; i++)
        ((DefaultTableModel) table.getModel()).addColumn(metaData.getColumnLabel(i));
    if (!res.first())
        JOptionPane.showMessageDialog(rootPane, "no data!");
    else
        do {
            Vector<Object> v = new Vector<Object>();
            for (int i = 1; i <= fieldsCount; i++)              
                v.addElement(res.getObject(i));         
            ((DefaultTableModel) table.getModel()).addRow(v);
        } while (res.next());
        res.close();
}

Actually, I think you may have discovered a bug in the week(...) function, or at least an error in the documentation. Hopefully someone will jump in and explain why I am wrong.

Looking at the code:

library(lubridate)
> week
function (x) 
yday(x)%/%7 + 1
<environment: namespace:lubridate>

The documentation states:

Weeks is the number of complete seven day periods that have occured between the date and January 1st, plus one.

But since Jan 1 is the first day of the year (not the zeroth), the first "week" will be a six day period. The code should (??) be

(yday(x)-1)%/%7 + 1

NB: You are using week(...) in the data.table package, which is the same code as lubridate::week except it coerces everything to integer rather than numeric for efficiency. So this function has the same problem (??).

From the documentation:

1. get cookie from response

   url = 'http://example.com/some/cookie/setting/url'
   r = requests.get(url)
   r.cookies
   

   {'example_cookie_name': 'example_cookie_value'}

2. give cookie back to server on subsequent request

   url = 'http://httpbin.org/cookies'
   cookies = dict(cookies_are='working')
   r = requests.get(url, cookies=cookies)`
   

If you use

git fetch --dry-run -v <link/to/remote/git/repo>

you'll get feedback about whether it is up-to-date. So basically, you just need to add the "verbose" option to the answer given before.

Add this line above you Query

SET IDENTITY_INSERT tbl_content ON

I can assure you that raw speed ultimately lies in the non-standard use of Indexes for blazing speed using large tables.

One thing that could have happened:

• 1: you create your serialized data with a given library A (version X)
• 2: you then try to read this data with the same library A (but version Y)

Hence, at compile time for the version X, the JVM will generate a first Serial ID (for version X) and it will do the same with the other version Y (another Serial ID).

When your program tries to de-serialize the data, it can't because the two classes do not have the same Serial ID and your program have no guarantee that the two Serialized objects correspond to the same class format.

Assuming you changed your constructor in the mean time and this should make sense to you.

There are several methods to get last inserted primary key id while using save method

$this->loadModel('Model');
$this->Model->save($this->data);

This will return last inserted id of the model current model

$this->Model->getLastInsertId();
$this->Model-> getInsertID();

This will return last inserted id of model with given model name

$this->Model->id;

This will return last inserted id of last loaded model

$this->id;

Simply you cannot do it with FF3.

The other option could be using applet or other controls to select and upload files.

I would do something like:

filename = "mynumbers.txt"
mynumbers = []
with open(filename) as f:
    for line in f:
        mynumbers.append([int(n) for n in line.strip().split(',')])
for pair in mynumbers:
    try:
        x,y = pair[0],pair[1]
        # Do Something with x and y
    except IndexError:
        print "A line in the file doesn't have enough entries."

The with open is recommended in http://docs.python.org/tutorial/inputoutput.html since it makes sure files are closed correctly even if an exception is raised during the processing.

I have a sheet that is made to used by others and I have quite a few indirect() references around, so I need to formulaically handle a changed sheet tab name.

I used the formula from JohnP2 (below) but was having trouble because it didn't update automatically when a sheet name was changed. You need to go to the actual formula, make an arbitrary change and refresh to run it again.

=REGEXREPLACE(CELL("address",'SHEET NAME'!A1),"'?([^']+)'?!.*","$1")

I solved this by using info found in this solution on how to force a function to refresh. It may not be the most elegant solution, but it forced Sheets to pay attention to this cell and update it regularly, so that it catches an updated sheet title.

=IF(TODAY()=TODAY(), REGEXREPLACE(CELL("address",'SHEET NAME'!A1),"'?([^']+)'?!.*","$1"), "")

Using this, Sheets know to refresh this cell every time you make a change, which results in the address being updated whenever it gets renamed by a user.

Try This... It's very simple just use confirm dialog box for alert with YES|NO.

if(confirm("Do you want to upgrade?")){ Your code }

We can create method for it. Simply use it.

public func createBorderForView(color: UIColor, radius: CGFloat, width: CGFloat = 0.7) {
    self.layer.borderWidth = width
    self.layer.cornerRadius = radius
    self.layer.shouldRasterize = false
    self.layer.rasterizationScale = 2
    self.clipsToBounds = true
    self.layer.masksToBounds = true
    let cgColor: CGColor = color.cgColor
    self.layer.borderColor = cgColor
}

Probably the best way is to use Guava

List<String> list = new ArrayList<String>();
list.add("How are you");
list.add("How you doing");
list.add("Joe");
list.add("Mike");
    
Collection<String> filtered = Collections2.filter(list,
    Predicates.containsPattern("How"));
print(filtered);

prints

How are you
How you doing

In case you want to get the filtered collection as a list, you can use this (also from Guava):

List<String> filteredList = Lists.newArrayList(Collections2.filter(
    list, Predicates.containsPattern("How")));

For a shopping cart situation here's what I recommend. I'm gonna break it down into it's simplest form.

Assuming we start with this(a list view with 2 colums, 2 buttons, and a label):

First things first, removing the items, to do that we'll enter our remove button:

private void button2_Click(object sender, EventArgs e)
{
    listView1.Items.Remove(listView1.SelectedItems[0]);
    label1.Text = updateCartTotal().ToString();
}

Now the second line is updating our labels total using the next function i'll post to addup all the total of column 2 in the listview:

private decimal updateCartTotal()
{
    decimal runningTotal = 0;
    foreach(ListViewItem l in listView1.Items)
    {
        runningTotal += Convert.ToDecimal(l.SubItems[1].Text);
    }
    return runningTotal;
}

You don't have to use decimal like I did, you can use float or int if you don't have decimals. So let's break it down. We use a for loop to total all the items in the column 2(SubItems[1].Text). Add that to a decimal we declared prior to the foreach loop to keep a total. If you want to do tax you can do something like:

return runningTotal * 1.15;

or whatever your tax rate is.

Long and short of it, using this function you can retotal your listview by just calling the function. You can change the labels text like I demo'd prior if that's what you're after.

Thought i'd throw this out there too:

the thing that worked for me was changing my build variant back to a variant that was working previously. For some reason i had changed this before (and i forgot why).

either way, the best thing to do is to try to remember what you changed that day (it could be something as minor as cleaning, or going back to a previous git commit)...etc.

it also helps to try to resync gradle and force a rebuild.

In Android you can check this with utility method isEmpty from TextUtils,

public static boolean isEmpty(CharSequence str) {
    return str == null || str.length() == 0;
}

isEmpty(CharSequence str) method check both condition, for null and length.

A scriptless, CSS-only experimental approach with image pre-loading^BONUS! and which only works in Firefox:

<style>
a.zoom .full { display: none; }
a.zoom:active .thumb { display: none; }
a.zoom:active .full { display: inline; }
</style>

<a class="zoom" href="#">
<img class="thumb" src="thumbnail.png"/>
<img class="full" src="fullsize.png"/>
</a>

Shows the thumbnail by default. Shows the full size image while the mouse button is clicked and held down. Goes back to the thumbnail as soon as the button is released. I'm in no way suggesting that this method be used; it's just a demo of a CSS-only approach that [very] partially solves the problem. With some z-index + relative position tweaks, it could work in other browsers too.

Old thread but thought I'd just add that the reason developers use this construct is not to create a dead link, but because javascript URLs for some reason do not pass references to the active html element correctly.

e.g. handler_function(this.id) works as onClick but not as a javascript URL.

Thus it's a choice between writing pedantically standards-compliant code that involves you in having to manually adjust the call for each hyperlink, or slightly non-standard code which can be written once and used everywhere.

If you are using RC5 then import this:

import { CommonModule } from '@angular/common';  
import { BrowserModule } from '@angular/platform-browser';

and be sure to import CommonModule from the module that is providing your component.

 @NgModule({
    imports: [CommonModule],
    declarations: [MyComponent]
  ...
})
class MyComponentModule {}

!members.find()

I think now the best way to solve this issue is code above. It works since Groovy 1.8.1 http://docs.groovy-lang.org/docs/next/html/groovy-jdk/java/util/Collection.html#find(). Examples:

def lst1 = []
assert !lst1.find()

def lst2 = [null]
assert !lst2.find()

def lst3 = [null,2,null]
assert lst3.find()

def lst4 = [null,null,null]
assert !lst4.find()

def lst5 = [null, 0, 0.0, false, '', [], 42, 43]
assert lst5.find() == 42

def lst6 = null; 
assert !lst6.find()

My situation and solution: I had created and enabled a HyperV ethernet adapter. For some reason, my main windows machine was using the "virtual" ethernet adapter instead of the 'hardware' adapter.

I disabled the virtual ethernet and my network settings to change the network public/privacy settings were revealed.

just use stoi/stol/stoll for example:

std::cout << std::stol("fffefffe", nullptr, 16) << std::endl;

output: 4294901758

I too have been frustrated by the lack of good graphical http clients available for Windows. So over the past couple years I've been developing one myself: I'm Only Resting, "a feature-rich WinForms-based HTTP client." It's open source (Apache License, Version 2.0) with freely available downloads.

It currently has fairly complete coverage of HTTP features except for file uploads, and it provides a very good user interface with great request and response management.

Here's a screenshot:

_{(source: swensensoftware.com)}

Looking at http.Request you can find the following member variables:

// HTTP defines that header names are case-insensitive.
// The request parser implements this by canonicalizing the
// name, making the first character and any characters
// following a hyphen uppercase and the rest lowercase.
//
// For client requests certain headers are automatically
// added and may override values in Header.
//
// See the documentation for the Request.Write method.
Header Header

// RemoteAddr allows HTTP servers and other software to record
// the network address that sent the request, usually for
// logging. This field is not filled in by ReadRequest and
// has no defined format. The HTTP server in this package
// sets RemoteAddr to an "IP:port" address before invoking a
// handler.
// This field is ignored by the HTTP client.
RemoteAddr string

You can use RemoteAddr to get the remote client's IP address and port (the format is "IP:port"), which is the address of the original requestor or the last proxy (for example a load balancer which lives in front of your server).

This is all you have for sure.

Then you can investigate the headers, which are case-insensitive (per documentation above), meaning all of your examples will work and yield the same result:

req.Header.Get("X-Forwarded-For") // capitalisation
req.Header.Get("x-forwarded-for") // doesn't
req.Header.Get("X-FORWARDED-FOR") // matter

This is because internally http.Header.Get will normalise the key for you. (If you want to access header map directly, and not through Get, you would need to use http.CanonicalHeaderKey first.)

Finally, "X-Forwarded-For" is probably the field you want to take a look at in order to grab more information about client's IP. This greatly depends on the HTTP software used on the remote side though, as client can put anything in there if it wishes to. Also, note the expected format of this field is the comma+space separated list of IP addresses. You will need to parse it a little bit to get a single IP of your choice (probably the first one in the list), for example:

// Assuming format is as expected
ips := strings.Split("10.0.0.1, 10.0.0.2, 10.0.0.3", ", ")
for _, ip := range ips {
    fmt.Println(ip)
}

will produce:

10.0.0.1
10.0.0.2
10.0.0.3

So after doing more investigating I ended up going with a slightly revised version of Method 3 (mgechev/angular2-seed).

I basically moved components to be a main level directory and then each feature will be inside of it.

1. In C++11, in addition to copy constructors, objects can have move constructors.
   (And in addition to copy assignment operators, they have move assignment operators.)
2. The move constructor is used instead of the copy constructor, if the object has type "rvalue-reference" (Type &&).
3. std::move() is a cast that produces an rvalue-reference to an object, to enable moving from it.

It's a new C++ way to avoid copies. For example, using a move constructor, a std::vector could just copy its internal pointer to data to the new object, leaving the moved object in an moved from state, therefore not copying all the data. This would be C++-valid.

Try googling for move semantics, rvalue, perfect forwarding.

You could also do this which would include all JARs in the local repository. This way you wouldn't have to specify it every time.

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

import datetime

todays_date = datetime.date.today()
print(todays_date)
>>> 2019-10-12

# adding strftime will remove the seconds
current_time = datetime.datetime.now().strftime('%H:%M')
print(current_time)
>>> 23:38

Perhaps you might want to use "addEventListener"

document.getElementById("test").addEventListener('click',function ()
{
    foo2();
   }  ); 

Hope it's still useful for you

Perhaps am late or maybe you've already used it before but there is another one called ksoap and its pretty amazing.. It also includes timeouts and can parse any SOAP based webservice efficiently. I also made a few changes to suit my parsing.. Look it up

It may be that the Windows Credential Manager is holding onto credentials for the network share.

Load up Credential Manager (the easiest way is perhaps just to Search for that in the Start Menu), see if there are any Windows Credentials for your network share, and try deleting/updating them.

Normally you should use __cplusplus define to detect c++17, but by default microsoft compiler does not define that macro properly, see https://devblogs.microsoft.com/cppblog/msvc-now-correctly-reports-__cplusplus/ - you need to either modify project settings to include /Zc:__cplusplus switch, or you could use syntax like this:

#if ((defined(_MSVC_LANG) && _MSVC_LANG >= 201703L) || __cplusplus >= 201703L)
     //C++17 specific stuff here
#endif

SELECT INTO

DECLARE
   the_variable NUMBER;

BEGIN
   SELECT my_column INTO the_variable FROM my_table;
END;

Make sure that the query only returns a single row:

By default, a SELECT INTO statement must return only one row. Otherwise, PL/SQL raises the predefined exception TOO_MANY_ROWS and the values of the variables in the INTO clause are undefined. Make sure your WHERE clause is specific enough to only match one row

If no rows are returned, PL/SQL raises NO_DATA_FOUND. You can guard against this exception by selecting the result of an aggregate function, such as COUNT(*) or AVG(), where practical. These functions are guaranteed to return a single value, even if no rows match the condition.

A SELECT ... BULK COLLECT INTO statement can return multiple rows. You must set up collection variables to hold the results. You can declare associative arrays or nested tables that grow as needed to hold the entire result set.

The implicit cursor SQL and its attributes %NOTFOUND, %FOUND, %ROWCOUNT, and %ISOPEN provide information about the execution of a SELECT INTO statement.

To repost:

After searching through many solutions I decided to blog about how to sort in jquery. In summary, steps to sort jquery "array-like" objects by data attribute...

1. select all object via jquery selector
2. convert to actual array (not array-like jquery object)
3. sort the array of objects
4. convert back to jquery object with the array of dom objects

Html

<div class="item" data-order="2">2</div>
<div class="item" data-order="1">1</div>
<div class="item" data-order="4">4</div>
<div class="item" data-order="3">3</div>

Plain jquery selector

$('.item');

[<div class="item" data-order="2">2</div>,
 <div class="item" data-order="1">1</div>,
 <div class="item" data-order="4">4</div>,
 <div class="item" data-order="3">3</div>
]

Lets sort this by data-order

function getSorted(selector, attrName) {
    return $($(selector).toArray().sort(function(a, b){
        var aVal = parseInt(a.getAttribute(attrName)),
            bVal = parseInt(b.getAttribute(attrName));
        return aVal - bVal;
    }));
}

> getSorted('.item', 'data-order')

[<div class="item" data-order="1">1</div>,
 <div class="item" data-order="2">2</div>,
 <div class="item" data-order="3">3</div>,
 <div class="item" data-order="4">4</div>
]

See how getSorted() works.

Hope this helps!

This how to make input password that has hint which not converted to * !!.

On XML :

android:inputType="textPassword"
android:gravity="center"
android:ellipsize="start"
android:hint="Input Password !."

thanks to : mango and rjrjr for the insight :D.

I don't know why

cfg_name_unique NOT LIKE '%categories%' 

still returns those two values, but maybe exclude them explicit:

SELECT *
    FROM developer_configurations_cms

    WHERE developer_configurations_cms.cat_id = '1'
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%'
    AND developer_configurations_cms.cfg_name_unique NOT LIKE '%categories%'
    AND developer_configurations_cms.cfg_name_unique NOT IN ('categories_posts', 'categories_news')

A colleague and I have created a tool just for this. It's a visual representation of all the locks that your sessions produce. Give it a try (http://www.sqllockfinder.com), it's open source (https://github.com/LucBos/SqlLockFinder)

I've found that it is best to change the title of the current view controller in the navigation stack to the desired text of the back button before pushing to the next view controller.

For instance

self.navigationItem.title = @"Desired back button text";
[self.navigationController pushViewController:QAVC animated:NO];

Then in the viewDidAppear set the title back to the desired title for the original VC. Voila!

For a more detailed answer on creating your own colormaps, I highly suggest visiting this page

If that answer is too much work, you can quickly make your own list of colors and pass them to the color parameter. All the colormaps are in the cm matplotlib module. Let's get a list of 30 RGB (plus alpha) color values from the reversed inferno colormap. To do so, first get the colormap and then pass it a sequence of values between 0 and 1. Here, we use np.linspace to create 30 equally-spaced values between .4 and .8 that represent that portion of the colormap.

from matplotlib import cm
color = cm.inferno_r(np.linspace(.4, .8, 30))
color

array([[ 0.865006,  0.316822,  0.226055,  1.      ],
       [ 0.851384,  0.30226 ,  0.239636,  1.      ],
       [ 0.832299,  0.283913,  0.257383,  1.      ],
       [ 0.817341,  0.270954,  0.27039 ,  1.      ],
       [ 0.796607,  0.254728,  0.287264,  1.      ],
       [ 0.775059,  0.239667,  0.303526,  1.      ],
       [ 0.758422,  0.229097,  0.315266,  1.      ],
       [ 0.735683,  0.215906,  0.330245,  1.      ],
       .....

Then we can use this to plot, using the data from the original post:

import random
x = [{i: random.randint(1, 5)} for i in range(30)]
df = pd.DataFrame(x)
df.plot(kind='bar', stacked=True, color=color, legend=False, figsize=(12, 4))

assuming input[row][col]

rows = len(input)
cols = len(list(zip(*input)))

Use Blazor http://learn-blazor.com/architecture/interop/

Here's the C#:

namespace BlazorDemo.Client
{
   public static class MyCSharpFunctions
   {
       public static void CsharpFunction()
       {
          // Notification.show();
       }
   }
}

Then the Javascript:

const CsharpFunction = Blazor.platform.findMethod(
"BlazorDemo.Client",
"BlazorDemo.Client",
"MyCSharpFunctions",
"CsharpFunction"
);
if (Javascriptcondition > 0) {
   Blazor.platform.callMethod(CsharpFunction, null)
}

It helped me to convert the result of simplexml_load_file($file) into a JSON Structure and decode it back:

$xml = simplexml_load_file("$token.xml");
$json = json_encode($xml);
$xml_fixed = json_decode($json);

$try1 = $xml->structure->{"@attributes"}['value'];
print_r($try1);

>> result: SimpleXMLElement Object
(
)

$try2 = $xml_fixed->structure->{"@attributes"}['value'];
print_r($try2);

>> result: stdClass Object
(
    [key] => value
)

You can resave the image and literally find the src file of your project and add it to that when you save. For me I had to go to netbeans and found my project and when that comes up it had 3 files src was the last. Don't click on any of them just save your pic there. That should work. Now resizing it may be a different issue and one I'm working on now lol

collect_set can help to get unique values from a given column of pyspark.sql.DataFrame df.select(F.collect_set("column").alias("column")).first()["column"]

You can find your team id here:

https://developer.apple.com/account/#/membership

This will get you to your Membership Details, just scroll down to Team ID

Even if above solutions don't work, check permissions to destination file of aws ec2 instance. May be you can try with- sudo chmod 777 -R destinationFolder/*

You should possibly make data a keyword parameter with a default value of empty dictionary:

class DHT:
    def __init__(self, data=dict()):
        self.data['one'] = '1'
        self.data['two'] = '2'
        self.data['three'] = '3'
    def showData(self):
        print(self.data)

if __name__ == '__main__': 
    DHT().showData()

Personally i prefer the format function, allows you to simply change the date part very easily.

     declare @format varchar(100) = 'yyyy/MM/dd'
     select 
        format(the_date,@format), 
        sum(myfield) 
     from mytable 
     group by format(the_date,@format) 
     order by format(the_date,@format) desc;

The functions with an s take string parameters. The others take file streams.

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.
