Nginx prefers prefix-based location matches (not involving regular expression), that's why in your code block, /stash redirects are going to /.

The algorithm used by Nginx to select which location to use is described thoroughly here: https://www.digitalocean.com/community/tutorials/understanding-nginx-server-and-location-block-selection-algorithms#matching-location-blocks

You can also try to set a HostnameVerifier as described here. This worked for me to avoid this error.

// Do not do this in production!!!
HostnameVerifier hostnameVerifier = org.apache.http.conn.ssl.SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;

DefaultHttpClient client = new DefaultHttpClient();

SchemeRegistry registry = new SchemeRegistry();
SSLSocketFactory socketFactory = SSLSocketFactory.getSocketFactory();
socketFactory.setHostnameVerifier((X509HostnameVerifier) hostnameVerifier);
registry.register(new Scheme("https", socketFactory, 443));
SingleClientConnManager mgr = new SingleClientConnManager(client.getParams(), registry);
DefaultHttpClient httpClient = new DefaultHttpClient(mgr, client.getParams());

// Set verifier     
HttpsURLConnection.setDefaultHostnameVerifier(hostnameVerifier);

// Example send http request
final String url = "https://encrypted.google.com/";  
HttpPost httpPost = new HttpPost(url);
HttpResponse response = httpClient.execute(httpPost);

Straight from the React docs:

fetch('https://mywebsite.com/endpoint/', {
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    firstParam: 'yourValue',
    secondParam: 'yourOtherValue',
  })
})

(This is posting JSON, but you could also do, for example, multipart-form.)

I found the answer:

$mail->AddEmbeddedImage('img/2u_cs_mini.jpg', 'logo_2u');

and on the <img> tag put src='cid:logo_2u'

Try This:

$(document).on('click', '#btnClick', function(){ _x000D_
    alert("button is clicked");_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
 <button id="btnClick">Click me</button> 

This is how you do it column-wise:

[df[col].update((df[col] - df[col].min()) / (df[col].max() - df[col].min())) for col in df.columns]

My understanding is that the connection limit is not changeable on the client side. The connection limit must be changed on the server to have any effect. By default, many servers will only allow 2 connections per unique client.

The client is not the browser, it is the client machine issuing the TCP/IP requests.

To see the effect very clearly, use something like JMeter to fire off a bunch of web service calls to your server host - it will accept the first two and will not accept another until one of the two is completed. The amazing thing about this is that for a SOA shop, this is critical, yet hardly anyone is really aware of it.

If the results come from a mysql query, it is more efficient to limit directly the mysql result:

select [...] from [...] order by [...] limit 0,10

where 10 is the max numbers of rows you want

An old thread, but since I didn't find it elsewhere, here is one more possibility:

If you're using servlet-api 3.0+, then your web.xml must NOT include metadata-complete="true" attribute

This tells tomcat to map the servlets using data given in web.xml instead of using the @WebServlet annotation.

If you use JSON properly, you can have nested object without any issue :

var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance 
var theUrl = "/json-handler";
xmlhttp.open("POST", theUrl);
xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
xmlhttp.send(JSON.stringify({ "email": "[email protected]", "response": { "name": "Tester" } }));

There is no specialized image component provided in Swing (which is sad in my opinion). So, there are a few options:

1. As @Reimeus said: Use a JLabel with an icon.

2. Create in the window builder a JPanel, that will represent the location of the image. Then add your own custom image component to the JPanel using a few lines of code you will never have to change. They should look like this:

   JImageComponent ic = new JImageComponent(myImageGoesHere);
   imagePanel.add(ic);
   

   where JImageComponent is a self created class that extends JComponent that overrides the paintComponent() method to draw the image.

You can use these solutions :

CSS rules applies to all tags that have following two classes :

.left.ui-class-selector {
    /*style here*/
}

CSS rules applies to all tags that have <li> with following two classes :

li.left.ui-class-selector {
   /*style here*/
}

jQuery solution :

$("li.left.ui-class-selector").css("color", "red");

Javascript solution :

document.querySelector("li.left.ui-class-selector").style.color = "red";

No your concepts are not right. And to set it right you need the answer to the question that you incorrectly answered:

What is meant by 32bit or 64 bit machine?

The answer to the question is "something significant in the CPU is 32bit or 64 bit". So the question is what is that something significant? Lot of people say the width of data bus that determine whether the machine is 32bit or 64 bit. But none of the latest 32 bit processors have 32 bit or 64 bit wide data buses. most 32 bit systems will have 36 bit at least to support more RAM. Most 64 bit processors have no more than 48bit wide data bus because that is hell lot of memory already.

So according to me a 32 bit or 64 bit machine is determined by the size of its general purpose registers used in computation or "the natural word size" used by the computer.

Note that a 32 bit OS is a different thing. You can have a 32 bit OS running on 64 bit computer. Additionally, you can have 32 bit application running on 64 bit OS. If you do not understand the difference, post another question.

So the maximum amount of RAM a processor can address is 2^(width of data bus in bits), given that the proper addressing mode is switched on in the processor.

Further note, there is nothing stopping someone to introduce a multiplex between data Bus and memory banks, that will select a bank and then address the RAM (in two steps). This way you can address even more RAM. But that is impractical, and highly inefficient.

The JSON format is often used for serializing and transmitting structured data over a network connection. It is used primarily to transmit data between a server and web application, serving as an alternative to XML.

This is incredible but real.

csrf filter is enabled by default and it actually blocks any POST, PUT or DELETE requests which do not include de csrf token.

Try using a GET instead of POST to confirm that this is it.

If this is so then allow any HTTP method:

@Throws(Exception::class)
override fun configure(http: HttpSecurity) {

    /**
     * Allow POST, PUT or DELETE request
     *
     * NOTE: csrf filter is enabled by default and it actually blocks any POST, PUT or DELETE requests
     * which do not include de csrf token.
     */
    http.csrf().disable()

}

If you are obtaining a 401 the most intuitive thing is to think that in the request you have No Auth or you are missing something in the headers regarding authorization.

But apparently there is an internal function that is filtering the HTTP methods that use POST and returns a 401. After fixing it I thought it was a cache issue with the status code but apparently not.

I made the following script:

# Link to binary tar.gz archive
# See https://maven.apache.org/download.cgi?html_a_name#Files

# Configuration parameters used to start up the JVM running Maven, i.e. "-Xms256m -Xmx512m"

  # Create nonexistent subdirectories recursively

  # Curl location of tar.gz archive & extract without first directory
  curl -L $MAVEN_BINARY_TAR_GZ_ARCHIVE | tar -xzf - -C $MAVEN_HOME --strip 1

This is almost certainly a bad idea. Certainly if the ordinal is de-facto persisted (e.g. because someone has bookmarked the URL) - it means that you must always preserve the enum ordering in future, which may not be obvious to code maintainers down the line.

Why not encode the enum using myEnumValue.name() (and decode via ReportTypeEnum.valueOf(s)) instead?

Try those methods, it should work:

• quit/exit Skype (make sure it's not running) because it reserves localhost:80
• disable Anti-virus (Try first to disable skype and running again, if it didn't work do this step)
• Right click on xampp control panel and run as administrator

I was in the same situation, wanting to .NET instead of a third party library. As another poster mentioned above, simply using the ZipPackage class (introduced in .NET 3.5) is not quite enough. There is an additional file that MUST be included in the archive in order for the ZipPackage to work. If this file is added, then the resulting ZIP package can be opened directly from Windows Explorer - no problem.

All you have to do is add the [Content_Types].xml file to the root of the archive with a "Default" node for every file extension you wish to include. Once added, I could browse the package from Windows Explorer or programmatically decompress and read its contents.

More information on the [Content_Types].xml file can be found here: http://msdn.microsoft.com/en-us/magazine/cc163372.aspx

Here is a sample of the [Content_Types].xml (must be named exactly) file:

<?xml version="1.0" encoding="utf-8" ?>
<Types xmlns=
    "http://schemas.openxmlformats.org/package/2006/content-types">
  <Default Extension="xml" ContentType="text/xml" /> 
  <Default Extension="htm" ContentType="text/html" /> 
  <Default Extension="html" ContentType="text/html" /> 
  <Default Extension="rels" ContentType=
    "application/vnd.openxmlformats-package.relationships+xml" /> 
  <Default Extension="jpg" ContentType="image/jpeg" /> 
  <Default Extension="png" ContentType="image/png" /> 
  <Default Extension="css" ContentType="text/css" /> 
</Types>

And the C# for creating a ZIP file:

var zipFilePath = "c:\\myfile.zip"; 
var tempFolderPath = "c:\\unzipped"; 

    using (Package package = ZipPackage.Open(zipFilePath, FileMode.Open, FileAccess.Read)) 
    { 
        foreach (PackagePart part in package.GetParts()) 
        { 
            var target = Path.GetFullPath(Path.Combine(tempFolderPath, part.Uri.OriginalString.TrimStart('/'))); 
            var targetDir = target.Remove(target.LastIndexOf('\\')); 

            if (!Directory.Exists(targetDir)) 
                Directory.CreateDirectory(targetDir); 

            using (Stream source = part.GetStream(FileMode.Open, FileAccess.Read)) 
            { 
                source.CopyTo(File.OpenWrite(target)); 
            } 
        } 
    } 

Note:

• This code uses the Stream.CopyTo method in .NET 4.0
• This will become much simpler with the introduction of the ZipArchive class in .NET 4.5: http://msdn.microsoft.com/en-us/library/system.io.compression.ziparchive(v=vs.110).aspx

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

In Kotlin List can be converted into ArrayList through passing it as a constructor parameter.

I had the same issue when I started using Puma in heroku as per their guide page, this issue was solved when I commented the port line shown below

# port        ENV['PORT']     || 3000

So, disabling the above line in the puma.rb in the config directory solved the issue

workers Integer(ENV['WEB_CONCURRENCY'] || 2)
threads_count = Integer(ENV['RAILS_MAX_THREADS'] || 5)
threads threads_count, threads_count

preload_app!

rackup      DefaultRackup
# port        ENV['PORT']     || 3000
environment ENV['RACK_ENV'] || 'production'

on_worker_boot do
  # Worker specific setup for Rails 4.1+
  # See: https://devcenter.heroku.com/articles/deploying-rails-applications-with-the-puma-web-server#on-worker-boot
  ActiveRecord::Base.establish_connection
end

Especially for the older Git versions, most of the suggestions won't work that well. If that's the case, I'd put a separate .gitignore in the directory where I want the content to be included regardless of other settings and allow there what is needed.

For example: /.gitignore

# ignore all .dll files
*.dll

/dependency_files/.gitignore

# include everything
!*

So everything in /dependency_files (even .dll files) are included just fine.

1. Open the created task scheduler

2. switch to the “Action” tab and select your created “Action”

3. In the Edit section, using the browser you could select powershell.exe in your system32\WindowsPowerShell\v1.0 folder.

      Example -C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
   

4. Next, in the ‘Add arguments’ -File parameter, paste your script file path in your system.

       Example – c:\GetMFAStatus.ps1

The Guava library contains convenience methods for creating lists and other collections which makes this much prettier than using the standard library classes.

Example:

ArrayList<String> list = newArrayList("a", "b", "c");

(This assumes import static com.google.common.collect.Lists.newArrayList;)

One place to start is the Blinux project:

http://leb.net/blinux/

That project describes how to get Emacspeak (editor with text-to-speech) and has a lot of other resources.

I worked with one person who's eye sight all but prevented them from using a monitor - they did well with Screen reader software and spent a lot of time using text based applications and the shell.

Wikipedia's list of screen reader packages is another place to start: http://en.wikipedia.org/wiki/List_of_screen_readers

If someone is interested in the similar problem, but is not working with XAML, here's my solution:

var B1 = new Border();
B1.BorderBrush = Brushes.Black;
B1.BorderThickness = new Thickness(0, 1, 0, 0); // You can specify here which borders do you want
YourPanel.Children.Add(B1);

I stumbled on this question because I want to use node.js with visual studio 2015 on my new computer with windows 10. I used node.js on windows 7 and 8 and 8.1 Never a problem node.js finding a module. I use a legacy node.js 0.10.39 because I have to use this version because of the serial and RFXCOM module.

The answer for windows 10 is to set the NODE_PATH in the enviroment variables with C:\Users\User\node_modules.

Your example shows the most simple way of passing PHP variables to JavaScript. You can also use json_encode for more complex things like arrays:

<?php
    $simple = 'simple string';
    $complex = array('more', 'complex', 'object', array('foo', 'bar'));
?>
<script type="text/javascript">
    var simple = '<?php echo $simple; ?>';
    var complex = <?php echo json_encode($complex); ?>;
</script>

Other than that, if you really want to "interact" between PHP and JavaScript you should use Ajax.

Using cookies for this is a very unsafe and unreliable way, as they are stored clientside and therefore open for any manipulation or won't even get accepted/saved. Don't use them for this type of interaction. jQuery.ajax is a good start IMHO.

You need to use -I with each directory. But you can still delimit the directories with whitespace if you use (GNU) make's foreach:

INC=$(DIR1) $(DIR2) ...
INC_PARAMS=$(foreach d, $(INC), -I$d)

splattne's answer probably covered most of everything so I won't repeat the same thing, but: inline and inline-block behave differently with the direction CSS property.

Within the next snippet you see one two (in order) is rendered, like it does in LTR layouts. I suspect the browser here auto-detected the English part as LTR text and rendered it from left to right.

body {_x000D_
  text-align: right;_x000D_
  direction: rtl;_x000D_
}_x000D_
_x000D_
h2 {_x000D_
  display: block; /* just being explicit */_x000D_
}_x000D_
_x000D_
span {_x000D_
  display: inline;_x000D_
}

<h2>_x000D_
  ??? ????? ????_x000D_
  <span>one</span>_x000D_
  <span>two</span>_x000D_
</h2>

However, if I go ahead and set display to inline-block, the browser appears to respect the direction property and render the elements from right to left in order, so that two one is rendered.

body {_x000D_
  text-align: right;_x000D_
  direction: rtl;_x000D_
}_x000D_
_x000D_
h2 {_x000D_
  display: block; /* just being explicit */_x000D_
}_x000D_
_x000D_
span {_x000D_
  display: inline-block;_x000D_
}

<h2>_x000D_
  ??? ????? ????_x000D_
  <span>one</span>_x000D_
  <span>two</span>_x000D_
</h2>

I don't know if there are any other quirks to this, I only found about this empirically on Chrome.

Just to clarify PHP uses copy on write, so basically everything is a reference until you modify it, but for objects you need to use clone and the __clone() magic method like in the accepted answer.

If you want to get the values of all checkboxes using jQuery, this might help you. This will parse the list and depending on the desired result, you can execute other code. BTW, for this purpose, one does not need to name the input with brackets []. I left them off.

  $(document).on("change", ".messageCheckbox", function(evnt){
    var data = $(".messageCheckbox");
    data.each(function(){
      console.log(this.defaultValue, this.checked);
      // Do something... 
    });
  }); /* END LISTENER messageCheckbox */

A Date object has no format, it is a representation. The date can be presented by a String with the format you like.

E.g. "yyyy-MM-dd", "yy-MMM-dd", "dd-MMM-yy" and etc.

To acheive this you can get the use of the SimpleDateFormat

Try this,

        String inputString = "19/05/2009"; // i.e. (dd/MM/yyyy) format

        SimpleDateFormat fromUser = new SimpleDateFormat("dd/MM/yyyy"); 
        SimpleDateFormat myFormat = new SimpleDateFormat("yyyy-MM-dd");

        try {
            Date dateFromUser = fromUser.parse(inputString); // Parse it to the exisitng date pattern and return Date type
            String dateMyFormat = myFormat.format(dateFromUser); // format it to the date pattern you prefer
            System.out.println(dateMyFormat); // outputs : 2009-05-19

        } catch (ParseException e) {
            e.printStackTrace();
        }

This outputs : 2009-05-19

The Magic is, you have to start with an empty selection, so put your cursor in front of the word/character you want to multi-select and press Ctrl+D .

Curtis's answer was very close to what I needed, but I changed it up a little.

Where he used:

$options['inputs']['name'][] = $new_input['name'];

I used:

$options[]['inputs']['name'] = $new_input['name'];

Here's my actual code using a query from a DB:

while($row=mysql_fetch_array($result)){ 
    $dtlg_array[]['dt'] = $row['dt'];
    $dtlg_array[]['lat'] = $row['lat'];
    $dtlg_array[]['lng'] = $row['lng'];
}

Thanks!

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'])

I was extending a DialogFragment and the above answer didnot work. I had to use getDialog() to achieve remove the title:

getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);

Do you mean tmux window? Ctrl + b + , if you have C-b as send prefix (it's by default)

Also C-b :rename-window <new name> and tmux rename-window <new name> work too.

As I know you can't rename pane

Swift 5 Solution:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    registerKeyboardNotifications()
}

func registerKeyboardNotifications() {
    NotificationCenter.default.addObserver(self,
                                         selector: #selector(keyboardWillShow(notification:)),
                                         name: UIResponder.keyboardWillShowNotification,
                                         object: nil)
    NotificationCenter.default.addObserver(self,
                                         selector: #selector(keyboardWillHide(notification:)),
                                         name: UIResponder.keyboardWillHideNotification,
                                         object: nil)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    NotificationCenter.default.removeObserver(self)
}

@objc func keyboardWillShow(notification: NSNotification) {
    let userInfo: NSDictionary = notification.userInfo! as NSDictionary
    let keyboardInfo = userInfo[UIResponder.keyboardFrameBeginUserInfoKey] as! NSValue
    let keyboardSize = keyboardInfo.cgRectValue.size
    let contentInsets = UIEdgeInsets(top: 0, left: 0, bottom: keyboardSize.height, right: 0)
    scrollView.contentInset = contentInsets
    scrollView.scrollIndicatorInsets = contentInsets
}

@objc func keyboardWillHide(notification: NSNotification) {
    scrollView.contentInset = .zero
    scrollView.scrollIndicatorInsets = .zero
}

Just to sum it up, 3 solutions:

• using toLowerCase() or toUpperCase
• using StringUtils of apache
• using regex

Now, what I was wondering was which one is the fastest? I'm guessing on average the first one.

If you want to set the form size programmatically, set the form's StartPosition property to Manual. Otherwise the form's own positioning and sizing algorithm will interfere with yours. This is why you are experiencing the problems mentioned in your question.

Example: Here is how I resize the form to a size half-way between its original size and the size of the screen's working area. I also center the form in the working area:

public MainView()
{
    InitializeComponent();

    // StartPosition was set to FormStartPosition.Manual in the properties window.
    Rectangle screen = Screen.PrimaryScreen.WorkingArea;
    int w = Width >= screen.Width ? screen.Width : (screen.Width + Width) / 2;
    int h = Height >= screen.Height ? screen.Height : (screen.Height + Height) / 2;
    this.Location = new Point((screen.Width - w) / 2, (screen.Height - h) / 2);
    this.Size = new Size(w, h);
}

Note that setting WindowState to FormWindowState.Maximized alone does not change the size of the restored window. So the window might look good as long as it is maximized, but when restored, the window size and location can still be wrong. So I suggest setting size and location even when you intend to open the window as maximized.

You can use position:absolute; to absolutely position an element within a parent div. When using position:absolute; the element will be positioned absolutely from the first positioned parent div, if it can't find one it will position absolutely from the window so you will need to make sure the content div is positioned.

To make the content div positioned, all position values that aren't static will work, but relative is the easiest since it doesn't change the divs positioning by itself.

So add position:relative; to the content div, remove the float from the button and add the following css to the button:

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

Do you want to match a class exactly, e.g. only matching FileInputStream instead of any subclass of FileInputStream? If so, use getClass() and ==. I would typically do this in an equals, so that an instance of X isn't deemed equal to an instance of a subclass of X - otherwise you can get into tricky symmetry problems. On the other hand, that's more usually useful for comparing that two objects are of the same class than of one specific class.

Otherwise, use instanceof. Note that with getClass() you will need to ensure you have a non-null reference to start with, or you'll get a NullPointerException, whereas instanceof will just return false if the first operand is null.

Personally I'd say instanceof is more idiomatic - but using either of them extensively is a design smell in most cases.

Try this if other answers did not work for you.

For me This happened for API 27 Emulator.

API 26 Emulator worked just fine. So I started API 26 Emulator first and then closed it.

Then I started API 27 Emulator and It worked with No errors at all.

Adding to Dmitri Chebotarev Answer,

If you want to alter multiple columns at a time , you can do it like below

DB::statement('
     ALTER TABLE `events` 
            MODIFY `event_date` DATE NOT NULL,
            MODIFY `event_start_time` TIME NOT NULL,
            MODIFY `event_end_time` TIME NOT NULL;
');

Another simple solution is to add jackson-databind dependency in POM.

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.8.1</version>
    </dependency>

Keep Rest of the code as it is.

The cors-everywhere addon works for me until Firefox 68, after 68 I need to adjust 'privacy.file_unique_origin' -> false (by open 'about:config') to solve 'CORS request not HTTP' for new CORS same-origin rule introduced.

Replace this line:

count(if(ccc_news_comments.id = 'approved', ccc_news_comments.id, 0)) AS comments

With this one:

coalesce(sum(ccc_news_comments.id = 'approved'), 0) comments

In bootstrap 4, they have designed a bigger input file.

A simple solution to increase the size input file is to use font-size:

Add you style, for example:

input[type="file"] {
  font-size:35px
}

Otherwise, you can make one custom class and add to input control.

A bin is range that represents the width of a single bar of the histogram along the X-axis. You could also call this the interval. (Wikipedia defines them more formally as "disjoint categories".)

The Numpy histogram function doesn't draw the histogram, but it computes the occurrences of input data that fall within each bin, which in turns determines the area (not necessarily the height if the bins aren't of equal width) of each bar.

In this example:

 np.histogram([1, 2, 1], bins=[0, 1, 2, 3])

There are 3 bins, for values ranging from 0 to 1 (excl 1.), 1 to 2 (excl. 2) and 2 to 3 (incl. 3), respectively. The way Numpy defines these bins if by giving a list of delimiters ([0, 1, 2, 3]) in this example, although it also returns the bins in the results, since it can choose them automatically from the input, if none are specified. If bins=5, for example, it will use 5 bins of equal width spread between the minimum input value and the maximum input value.

The input values are 1, 2 and 1. Therefore, bin "1 to 2" contains two occurrences (the two 1 values), and bin "2 to 3" contains one occurrence (the 2). These results are in the first item in the returned tuple: array([0, 2, 1]).

Since the bins here are of equal width, you can use the number of occurrences for the height of each bar. When drawn, you would have:

• a bar of height 0 for range/bin [0,1] on the X-axis,
• a bar of height 2 for range/bin [1,2],
• a bar of height 1 for range/bin [2,3].

You can plot this directly with Matplotlib (its hist function also returns the bins and the values):

>>> import matplotlib.pyplot as plt
>>> plt.hist([1, 2, 1], bins=[0, 1, 2, 3])
(array([0, 2, 1]), array([0, 1, 2, 3]), <a list of 3 Patch objects>)
>>> plt.show()

A pointer to void is a "generic" pointer type. A void * can be converted to any other pointer type without an explicit cast. You cannot dereference a void * or do pointer arithmetic with it; you must convert it to a pointer to a complete data type first.

void * is often used in places where you need to be able to work with different pointer types in the same code. One commonly cited example is the library function qsort:

void qsort(void *base, size_t nmemb, size_t size, 
           int (*compar)(const void *, const void *));

base is the address of an array, nmemb is the number of elements in the array, size is the size of each element, and compar is a pointer to a function that compares two elements of the array. It gets called like so:

int iArr[10];
double dArr[30];
long lArr[50];
...
qsort(iArr, sizeof iArr/sizeof iArr[0], sizeof iArr[0], compareInt);
qsort(dArr, sizeof dArr/sizeof dArr[0], sizeof dArr[0], compareDouble);
qsort(lArr, sizeof lArr/sizeof lArr[0], sizeof lArr[0], compareLong);

The array expressions iArr, dArr, and lArr are implicitly converted from array types to pointer types in the function call, and each is implicitly converted from "pointer to int/double/long" to "pointer to void".

The comparison functions would look something like:

int compareInt(const void *lhs, const void *rhs)
{
  const int *x = lhs;  // convert void * to int * by assignment
  const int *y = rhs;

  if (*x > *y) return 1;
  if (*x == *y) return 0;
  return -1;
}

By accepting void *, qsort can work with arrays of any type.

The disadvantage of using void * is that you throw type safety out the window and into oncoming traffic. There's nothing to protect you from using the wrong comparison routine:

qsort(dArr, sizeof dArr/sizeof dArr[0], sizeof dArr[0], compareInt);

compareInt is expecting its arguments to be pointing to ints, but is actually working with doubles. There's no way to catch this problem at compile time; you'll just wind up with a missorted array.

In my case I just ignored the following in application.properties file:

# Hibernate

#spring.jpa.hibernate.ddl-auto=update

It works for me....

I would do it this way:

UPDATE YourTable SET B = COALESCE(B, A);

COALESCE is a function that returns its first non-null argument.

In this example, if B on a given row is not null, the update is a no-op.

If B is null, the COALESCE skips it and uses A instead.

Install Django pylint:

pip install pylint-django

ctrl+shift+p > Preferences: Configure Language Specific Settings > Python

The settings.json available for python language should look like the below:

    ],

    "[python]": {

If you have the web view figured out but your images are still out of scale, the best solution I found (here) was simply prepending the document with:

<style>img{display: inline; height: auto; max-width: 100%;}</style>

As a result all images are scaled to match the web view width.

Since your list doesn't appear to be sorted, you have to iterate over its elements. Apply startsWith() or contains() to each element, and store matches in an auxiliary list. Return the auxiliary list when done.

I found very in-depth videos which cover $watch, $apply, $digest and digest cycles in:

• AngularJS - Understanding Watcher, $watch, $watchGroup, $watchCollection, ng-change

• AngularJS - Understanding digest cycle (digest phase or digest process or digest loop)

• AngularJS Tutorial - Understanding $apply and $digest (in depth)

Following are a couple of slides used in those videos to explain the concepts (just in case, if the above links are removed/not working).

In the above image, "$scope.c" is not being watched as it is not used in any of the data bindings (in markup). The other two ($scope.a and $scope.b) will be watched.

From the above image: Based on the respective browser event, AngularJS captures the event, performs digest cycle (goes through all the watches for changes), execute watch functions and update the DOM. If not browser events, the digest cycle can be manually triggered using $apply or $digest.

More about $apply and $digest:

The Datetime format field has the following format 'YYYY-MM-DD HH:MM:SS.S'

That statement is false. That's just how Enterprise Manager or SQL Server chooses to show the date. Internally it's a 8-byte binary value, which is why some of the functions posted by Andrew will work so well.

Kibbee makes a valid point as well, and in a perfect world I would agree with him. However, sometimes you want to bind query results directly to display control or widgets and there's really not a chance to do any formatting. And sometimes the presentation layer lives on a web server that's even busier than the database. With those in mind, it's not necessarily a bad thing to know how to do this in SQL.

Like this:

sleep(num_secs)

The num_secs value can be an integer or float.

Also, if you're writing this within a Rails app, or have included the ActiveSupport library in your project, you can construct longer intervals using the following convenience syntax:

sleep(4.minutes)
# or, even longer...
sleep(2.hours); sleep(3.days) # etc., etc.
# or shorter
sleep(0.5) # half a second

In IIS10 (Windows 10 and Server 2016), from version 1709 onwards, there is a new, simpler option for enabling HSTS for a website.

Microsoft describe the advantages of the new approach here, and provide many different examples of how to implement the change programmatically or by directly editing the ApplicationHost.config file (which is like web.config but operates at the IIS level, rather than individual site level). ApplicationHost.config can be found in C:\Windows\System32\inetsrv\config.

I've outlined two of the example methods here to avoid link rot.

Method 1 - Edit the ApplicationHost.config file directly Between the <site> tags, add this line:

<hsts enabled="true" max-age="31536000" includeSubDomains="true" redirectHttpToHttps="true" />

Method 2 - Command Line: Execute the following from an elevated command prompt (i.e. right mouse on CMD and run as administrator). Remember to swap Contoso with the name of your site as it appears in IIS Manager.

c:
cd C:\WINDOWS\system32\inetsrv\
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.enabled:True" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.max-age:31536000" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.includeSubDomains:True" /commit:apphost
appcmd.exe set config -section:system.applicationHost/sites "/[name='Contoso'].hsts.redirectHttpToHttps:True" /commit:apphost

The other methods Microsoft offer in that articles might be better options if you are on a hosted environment where you have limited access.

Keep in mind that IIS10 version 1709 is available on Windows 10 now, but for Windows Server 2016 it is on a different release track, and won't be released as a patch or service pack. See here for details about 1709.

How about

sub foo()
  dim r As Range, rows As Long, i As Long
  Set r = ActiveSheet.Range("A1:Z50")
  rows = r.rows.Count
  For i = rows To 1 Step (-1)
    If WorksheetFunction.CountA(r.rows(i)) = 0 Then r.rows(i).Delete
  Next
End Sub

Try this

Option Explicit

Sub Sample()
    Dim i As Long
    Dim DelRange As Range

    On Error GoTo Whoa

    Application.ScreenUpdating = False

    For i = 1 To 50
        If Application.WorksheetFunction.CountA(Range("A" & i & ":" & "Z" & i)) = 0 Then
            If DelRange Is Nothing Then
                Set DelRange = Range("A" & i & ":" & "Z" & i)
            Else
                Set DelRange = Union(DelRange, Range("A" & i & ":" & "Z" & i))
            End If
        End If
    Next i

    If Not DelRange Is Nothing Then DelRange.Delete shift:=xlUp
LetsContinue:
    Application.ScreenUpdating = True

    Exit Sub
Whoa:
    MsgBox Err.Description
    Resume LetsContinue
End Sub

IF you want to delete the entire row then use this code

Option Explicit

Sub Sample()
    Dim i As Long
    Dim DelRange As Range

    On Error GoTo Whoa

    Application.ScreenUpdating = False

    For i = 1 To 50
        If Application.WorksheetFunction.CountA(Range("A" & i & ":" & "Z" & i)) = 0 Then
            If DelRange Is Nothing Then
                Set DelRange = Rows(i)
            Else
                Set DelRange = Union(DelRange, Rows(i))
            End If
        End If
    Next i

    If Not DelRange Is Nothing Then DelRange.Delete shift:=xlUp
LetsContinue:
    Application.ScreenUpdating = True

    Exit Sub
Whoa:
    MsgBox Err.Description
    Resume LetsContinue
End Sub

You are missing the most obvious and fast answer especially when you need to do this in GUI in order to fix some weird word-wrap.

• Open gedit

• Then Ctrl + H, then put in the Find textbox \n and in Replace with an empty space then fill checkbox Regular expression and voila.

os.stat https://docs.python.org/2/library/stat.html#module-stat

edit: In newer code you should probably use os.path.getmtime() (thanks Christian Oudard)
but note that it returns a floating point value of time_t with fraction seconds (if your OS supports it)

getItemViewType(int position) is the key

In my opinion,the starting point to create this kind of recyclerView is the knowledge of this method. Since this method is optional to override therefore it is not visible in RecylerView class by default which in turn makes many developers(including me) wonder where to begin. Once you know that this method exists, creating such RecyclerView would be a cakewalk.

How to do it ?

You can create a RecyclerView with any number of different Views(ViewHolders). But for better readability lets take an example of RecyclerView with two Viewholders.
Remember these 3 simple steps and you will be good to go.

• Override public int getItemViewType(int position)
• Return different ViewHolders based on the ViewType in onCreateViewHolder() method

• Populate View based on the itemViewType in onBindViewHolder() method

  Here is a code snippet for you

  public class YourListAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
  
      private static final int LAYOUT_ONE= 0;
      private static final int LAYOUT_TWO= 1;
  
      @Override
      public int getItemViewType(int position)
      {
          if(position==0)
             return LAYOUT_ONE;
          else
             return LAYOUT_TWO;
      }
  
      @Override
      public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
  
          View view =null;
          RecyclerView.ViewHolder viewHolder = null;
  
          if(viewType==LAYOUT_ONE)
          {
             view = LayoutInflater.from(parent.getContext()).inflate(R.layout.one,parent,false);
             viewHolder = new ViewHolderOne(view);
          }
          else
          {
             view = LayoutInflater.from(parent.getContext()).inflate(R.layout.two,parent,false);
             viewHolder= new ViewHolderTwo(view);
          }
  
          return viewHolder;
      }
  
      @Override
      public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
  
         if(holder.getItemViewType()== LAYOUT_ONE)
         {
             // Typecast Viewholder 
             // Set Viewholder properties 
             // Add any click listener if any 
         }
         else {
  
             ViewHolderOne vaultItemHolder = (ViewHolderOne) holder;
             vaultItemHolder.name.setText(displayText);
             vaultItemHolder.name.setOnClickListener(new View.OnClickListener() {
                 @Override
                 public void onClick(View v) {
                     .......
                 }
             });
  
         }
  
     }
  
     /****************  VIEW HOLDER 1 ******************//
  
     public class ViewHolderOne extends RecyclerView.ViewHolder {
  
         public TextView name;
  
         public ViewHolderOne(View itemView) {
         super(itemView);
         name = (TextView)itemView.findViewById(R.id.displayName);
         }
     }
  
  
    //****************  VIEW HOLDER 2 ******************//
  
    public class ViewHolderTwo extends RecyclerView.ViewHolder{
  
         public ViewHolderTwo(View itemView) {
         super(itemView);
  
             ..... Do something
         }
    }
  }

Here is a project where I have implemented a RecyclerView with multiple ViewHolders.

This script will add a div that covers the entire window as the page loads. It will show a CSS-only loading spinner automatically. It will wait until the window (not the document) finishes loading, then it will wait an optional extra few seconds.

• Works with jQuery 3 (it has a new window load event)
• No image needed but it's easy to add one
• Change the delay for more branding or instructions
• Only dependency is jQuery.

Yes you can. I have installed a complete Debian distribution in a chroot-jail enviroment using debootstrap. (You need a rooted device) I am now running ssh, apache, mysql, php and even a samba server under android on my htc-desire with no problems. It is possible to run x applications using a remote x server via ssh. It even runs openoffice.org and firefox. You can use this: http://code.google.com/p/android-xserver/ to run X-application on localhost but my HTC-desire has a to small screen to be productive :-) But it might be usefull on a Eee Pad Transformer or something like that.

The purpose is typically just to restrict the scope of the nested class. Nested classes compared to normal classes have the additional possibility of the private modifier (as well as protected of course).

Basically, if you only need to use this class from within the "parent" class (in terms of scope), then it is usually appropiate to define it as a nested class. If this class might need to be used from without the assembly/library, then it is usually more convenient to the user to define it as a separate (sibling) class, whether or not there is any conceptual relationship between the two classes. Even though it is technically possible to create a public class nested within a public parent class, this is in my opinion rarely an appropiate thing to implement.

Very simple was to renew your certificate. Go to your developer member centre and go to your Provisioning profile and see what are the certificate Active and InActive and select Inactive certificate and hit Edit button then hit generate button. Now your certificate successful renewal for another 1 year. Thanks

1. First make sure you have installed MYsql+Sqlyog(if you are using it.).

2. • Start Registry Editor (Regedt32.exe).

• Locate the following key in the registry:

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters On the Edit menu, click Add Value, and then add the following registry value:

     Value Name: MaxUserPort
     Data Type: REG_DWORD
     Value: 65534
  

  This sets the number of ephemeral ports available to any user. The valid range is between 5000 and 65534 (decimal). The default value is 0x1388 (5000 decimal).

  On the Edit menu, click Add Value, and then add the following registry value:

     Value Name: TcpTimedWaitDelay
     Data Type: REG_DWORD
     Value: 30
  

  This sets the number of seconds to hold a TCP port connection in TIME_WAIT state before closing. The valid range is between 30 and 300 decimal, although you may wish to check with Microsoft for the latest permitted values. The default value is 0x78 (120 decimal).

  Quit Registry Editor.
  
  Reboot the machine.
  

I Had the same problem.

The solution for me is:

You must have the same version of: Microsoft.ReportViewer.ProcessingObjectModel registred in C:\Windows\assembly\GAC_MSIL\Microsoft.ReportViewer.ProcessingObjectModel, like you have registraded in web.config in developer server:

In my case i was only registred the 13. version in my prodution server and i have the 12. version in developer server.

the solution is install the version 12. in the prodution server too

the version 12. :

https://download.microsoft.com/download/A/1/2/A129F694-233C-4C7C-860F-F73139CF2E01/ENU/x86/ReportViewer.msi

Then now i have the version 12. in the prodution and the report work fine.

*** Remember to reset your IIS after instalation

The modern solution that works in node and across over 90% of all browsers (except IE and Opera Mini) is to use Number.isInteger followed by a simple positive check.

Number.isInteger(x) && x > 0

This was finalized in ECMAScript 2015.

function isPositiveInteger(x) {
    return Number.isInteger(x) && x > 0
}

The Polyfil is:

Number.isInteger = Number.isInteger || function(value) {
  return typeof value === 'number' && 
    isFinite(value) && 
    Math.floor(value) === value;
};

If you need to support input that might be in string or number form then you can use this function I wrote a large test suite against after all the existing answers (2/1/2018) failed on some form of input.

function isPositiveInteger(v) {
  var i;
  return v && (i = parseInt(v)) && i > 0 && (i === v || ''+i === v);
}

For example, you can try:

//If you want to get user, you need start query in your mysql:
SELECT user(); // output your user: root@localhost
SELECT system_user(); // --

//If you want to get port your "mysql://user:pass@hostname:port/db"
SELECT @@port; //3306 is default

//If you want hostname your db, you can execute query
SELECT @@hostname;

UPDATE 2014-11-14: The solution below is too old, I recommend using flex box layout method. Here is a overview: http://learnlayout.com/flexbox.html

The comment for orderBy source code notes: Keys are field and values are the order, being either ASC or DESC.. So you can do orderBy->(['field' => Criteria::ASC]).

I have solved this if you are using array called for 2 tables. Example you have, $tableA['yellow'] and $tableA['blue'] . You are getting these 2 values and you want to add another element inside them to separate them by their type.

foreach ($tableA['yellow'] as $value) {
    $value->type = 'YELLOW';  //you are adding new element named 'type'
}

foreach ($tableA['blue'] as $value) {
    $value->type = 'BLUE';  //you are adding new element named 'type'
}

So, both of the tables value will have new element called type.

Somebody posted quite a few form fields to your page. The new default max introduced by the recent security update is 1000.

Try adding the following setting in your web.config's <appsettings> block. in this block you are maximizing the MaxHttpCollection values this will override the defaults set by .net Framework. you can change the value accordingly as per your form needs

<appSettings>
    <add key="aspnet:MaxHttpCollectionKeys" value="2001" />
 </appSettings>

For more information please read this post. For more insight into the security patch by microsoft you can read this Knowledge base article

Also with python3 you might find convenient to use Extended Iterable Unpacking to handle optional positional arguments without additional dependencies:

try:
   _, arg1, arg2, arg3, *_ = sys.argv + [None] * 2
except ValueError:
   print("Not enough arguments", file=sys.stderr) # unhandled exception traceback is meaningful enough also
   exit(-1)

The above argv unpack makes arg2 and arg3 "optional" - if they are not specified in argv, they will be None, while if the first is not specified, ValueError will be thouwn:

Traceback (most recent call last):
  File "test.py", line 3, in <module>
    _, arg1, arg2, arg3, *_ = sys.argv + [None] * 2
ValueError: not enough values to unpack (expected at least 4, got 3)

Yes, you must open php.ini and remove the semicolon to:

;extension=php_openssl.dll

If you don't have that line, check that you have the file (In my PC is on D:\xampp\php\ext) and add this to php.ini in the "Dynamic Extensions" section:

extension=php_openssl.dll

Things have changed for PHP > 7. This is what i had to do for PHP 7.2.

Step: 1: Uncomment extension=openssl

Step: 2: Uncomment extension_dir = "ext"

Step: 3: Restart xampp.

Done.

Explanation: ( From php.ini )

If you wish to have an extension loaded automatically, use the following syntax:

extension=modulename

Note : The syntax used in previous PHP versions (extension=<ext>.so and extension='php_<ext>.dll) is supported for legacy reasons and may be deprecated in a future PHP major version. So, when it is possible, please move to the new (extension=<ext>) syntax.

Special Note: Be sure to appropriately set the extension_dir directive.

I got this problem too. In macos, here is the solution:

• Step 1: brew restall python. now you got python3.7 instead of the old python

• Step 2: build the new env base on python3.7. my path is /usr/local/Cellar/python/3.7.2/bin/python3.7

now, you'll not being disturbed by this problem.

I've been frustrated by this problem as well. Find/Replace can be helpful though, because if you don't put anything in the "replace" field it will replace with an -actual- NULL. So the steps would be something along the lines of:

1: Place some unique string in your formula in place of the NULL output (i like to use a password-like string)

2: Run your formula

3: Open Find/Replace, and fill in the unique string as the search value. Leave "replace with" blank

4: Replace All

Obviously, this has limitations. It only works when the context allows you to do a find/replace, so for more dynamic formulas this won't help much. But, I figured I'd put it up here anyway.

We can use flatmap for this, please refer below code :

 List<Integer> i1= Arrays.asList(1, 2, 3, 4);
 List<Integer> i2= Arrays.asList(5, 6, 7, 8);

 List<List<Integer>> ii= Arrays.asList(i1, i2);
 System.out.println("List<List<Integer>>"+ii);
 List<Integer> flat=ii.stream().flatMap(l-> l.stream()).collect(Collectors.toList());
 System.out.println("Flattened to List<Integer>"+flat);

CREATE PROCEDURE UpdateTables
AS
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;
    DECLARE @RowCount1 INTEGER
    DECLARE @RowCount2 INTEGER
    DECLARE @RowCount3 INTEGER
    DECLARE @RowCount4 INTEGER

    UPDATE Table1 Set Column = 0 WHERE Column IS NULL
    SELECT @RowCount1 = @@ROWCOUNT
    UPDATE Table2 Set Column = 0 WHERE Column IS NULL
    SELECT @RowCount2 = @@ROWCOUNT
    UPDATE Table3 Set Column = 0 WHERE Column IS NULL
    SELECT @RowCount3 = @@ROWCOUNT
    UPDATE Table4 Set Column = 0 WHERE Column IS NULL
    SELECT @RowCount4 = @@ROWCOUNT

    SELECT @RowCount1 AS Table1, @RowCount2 AS Table2, @RowCount3 AS Table3, @RowCount4 AS Table4
END

That didn't really work in my case - i.e. in order to overwrite hosts file you have to follow it's directions, ie:

./emulator -avd myEmulatorName -partition-size 280

and then in other term window (pushing new hosts file /tmp/hosts):

./adb remount
./adb push /tmp/hosts /system/etc

If you want distinct values from only two fields, plus return other fields with them, then the other fields must have some kind of aggregation on them (sum, min, max, etc.), and the two columns you want distinct must appear in the group by clause. Otherwise, it's just as Decker says.

It is possible you use the bash program, with the parameter -c for execute the commands:

bashCommand = "cwm --rdf test.rdf --ntriples > test.nt"
output = subprocess.check_output(['bash','-c', bashCommand])

You might be looking for this Microsoft Ajax Content Delivery Network So you could just add

<script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.min.js" type="text/javascript"></script>

To your aspx page.

The general answer to this question is:

Don't geocode known locations every time you load your page. Geocode them off-line and use the resulting coordinates to display the markers on your page.

The limits exist for a reason.

If you can't geocode the locations off-line, see this page (Part 17 Geocoding multiple addresses) from Mike Williams' v2 tutorial which describes an approach, port that to the v3 API.

You are missing that rsync can also compare files by checksum.

--size-only means that rsync will skip files that match in size, even if the timestamps differ. This means it will synchronise fewer files than the default behaviour. It will miss any file with changes that don't affect the overall file size. If you have something that changes the dates on files without changing the files, and you don't want rsync to spend lots of time checksumming those files to discover they haven't changed, this is the option to use.

--ignore-times means that rsync will checksum every file, even if the timestamps and file sizes match. This means it will synchronise more files than the default behaviour. It will include changes to files even where the file size is the same and the modification date/time has been reset to the original value. Checksumming every file means it has to be entirely read from disk, which may be slow. Some build pipelines will reset timestamps to a specific date (like 1970-01-01) to ensure that the final build file is reproducible bit for bit, e.g. when packed into a tar file that saves the timestamps.

You can also look at the jquery FormatCurrency plugin (of which I am the author); it has support for multiple locales as well, but may have the overhead of the currency support that you don't need.

$(this).formatCurrency({ symbol: '', roundToDecimalPlace: 0 });

See Branching Statements for more details and code samples:

break

The break statement has two forms: labeled and unlabeled. You saw the unlabeled form in the previous discussion of the switch statement. You can also use an unlabeled break to terminate a for, while, or do-while loop [...]

An unlabeled break statement terminates the innermost switch, for, while, or do-while statement, but a labeled break terminates an outer statement.

continue

The continue statement skips the current iteration of a for, while , or do-while loop. The unlabeled form skips to the end of the innermost loop's body and evaluates the boolean expression that controls the loop. [...]

A labeled continue statement skips the current iteration of an outer loop marked with the given label.

Here is my approach for Bootstrap 2.x. It is just some css. No JavaScript needed:

    .accordion-caret .accordion-toggle:hover {
        text-decoration: none;
    }
    .accordion-caret .accordion-toggle:hover span,
    .accordion-caret .accordion-toggle:hover strong {
        text-decoration: underline;
    }
    .accordion-caret .accordion-toggle:before {
        font-size: 25px;
        vertical-align: -3px;
    }
    .accordion-caret .accordion-toggle:not(.collapsed):before {
        content: "?";
        margin-right: 0px;
    }
    .accordion-caret .accordion-toggle.collapsed:before {
        content: "?";
        margin-right: 0px;
    }

Just add class accordion-caret to the accordion-group div, like this:

<div class="accordion-group accordion-caret">
    <div class="accordion-heading">
        <a class="accordion-toggle" data-toggle="collapse" href="#collapseOne">
            <strong>Header</strong>
        </a>
    </div>
    <div id="collapseOne" class="accordion-body collapse in">
        <div class="accordion-inner">
            Content
        </div>
    </div>
</div>

Converting our integer value to std::string so we can know how long (how long number of digits).

Then we creating char array length of string letter size +1, so we can copy our value to string then char array.

#include <string>

char* intToStr(int data) {
    std::string strData = std::to_string(data);

    char* temp = new char[strData.length() + 1];
    strcpy(temp, strData.c_str());

   return temp;
}

you will need to do it like this...

<a type="button" href="http://www.facebook.com/" value="facebook" target="_blank" class="button"></a>

and add the basic css if you want it to look like a btn.. like this

    .button {
    width:100px;
    height:50px;
    -moz-box-shadow:inset 0 1px 0 0 #fff;
    -webkit-box-shadow:inset 0 1px 0 0 #fff;
    box-shadow:inset 0 1px 0 0 #fff;
    background:-webkit-gradient( linear, left top, left bottom, color-stop(0.05, #ffffff), color-stop(1, #d1d1d1) );
    background:-moz-linear-gradient( center top, #ffffff 5%, #d1d1d1 100% );
 filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffffff', endColorstr='#d1d1d1');
    background-color:#fff;
    -moz-border-radius:6px;
    -webkit-border-radius:6px;
    border-radius:6px;
    border:1px solid #dcdcdc;
    display:inline-block;
    color:#777;
    font-family:Helvetica;
    font-size:15px;
    font-weight:700;
    padding:6px 24px;
    text-decoration:none;
    text-shadow:1px 1px 0 #fff
}



  .button:hover {
    background:-webkit-gradient( linear, left top, left bottom, color-stop(0.05, #d1d1d1), color-stop(1, #ffffff) );
    background:-moz-linear-gradient( center top, #d1d1d1 5%, #ffffff 100% );
 filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#d1d1d1', endColorstr='#ffffff');
    background-color:#d1d1d1
}
.button:active {
    position:relative;
    top:1px
}

target works only with href tags..

SHA1 is a one way hash. So you can not really revert it.

That's why applications use it to store the hash of the password and not the password itself.

Like every hash function SHA-1 maps a large input set (the keys) to a smaller target set (the hash values). Thus collisions can occur. This means that two values of the input set map to the same hash value.

Obviously the collision probability increases when the target set is getting smaller. But vice versa this also means that the collision probability decreases when the target set is getting larger and SHA-1's target set is 160 bit.

Jeff Preshing, wrote a very good blog about Hash Collision Probabilities that can help you to decide which hash algorithm to use. Thanks Jeff.

In his blog he shows a table that tells us the probability of collisions for a given input set.

As you can see the probability of a 32-bit hash is 1 in 2 if you have 77163 input values.

A simple java program will show us what his table shows:

public class Main {

    public static void main(String[] args) {
        char[] inputValue = new char[10];

        Map<Integer, String> hashValues = new HashMap<Integer, String>();

        int collisionCount = 0;

        for (int i = 0; i < 77163; i++) {
            String asString = nextValue(inputValue);
            int hashCode = asString.hashCode();
            String collisionString = hashValues.put(hashCode, asString);
            if (collisionString != null) {
                collisionCount++;
                System.out.println("Collision: " + asString + " <-> " + collisionString);
            }
        }

        System.out.println("Collision count: " + collisionCount);
    }

    private static String nextValue(char[] inputValue) {
        nextValue(inputValue, 0);

        int endIndex = 0;
        for (int i = 0; i < inputValue.length; i++) {
            if (inputValue[i] == 0) {
                endIndex = i;
                break;
            }
        }

        return new String(inputValue, 0, endIndex);
    }

    private static void nextValue(char[] inputValue, int index) {
        boolean increaseNextIndex = inputValue[index] == 'z';

        if (inputValue[index] == 0 || increaseNextIndex) {
            inputValue[index] = 'A';
        } else {
            inputValue[index] += 1;
        }

        if (increaseNextIndex) {
            nextValue(inputValue, index + 1);
        }

    }

}

My output end with:

Collision: RvV <-> SWV
Collision: SvV <-> TWV
Collision: TvV <-> UWV
Collision: UvV <-> VWV
Collision: VvV <-> WWV
Collision: WvV <-> XWV
Collision count: 35135

It produced 35135 collsions and that's the nearly the half of 77163. And if I ran the program with 30084 input values the collision count is 13606. This is not exactly 1 in 10, but it is only a probability and the example program is not perfect, because it only uses the ascii chars between A and z.

Let's take the last reported collision and check

System.out.println("VvV".hashCode());
System.out.println("WWV".hashCode());

My output is

86390
86390

Conclusion:

If you have a SHA-1 value and you want to get the input value back you can try a brute force attack. This means that you have to generate all possible input values, hash them and compare them with the SHA-1 you have. But that will consume a lot of time and computing power. Some people created so called rainbow tables for some input sets. But these do only exist for some small input sets.

And remember that many input values map to a single target hash value. So even if you would know all mappings (which is impossible, because the input set is unbounded) you still can't say which input value it was.

Alright, so let's first start with making the distinction between Javascript in a web browser, and Javascript on a server (CommonJS and Node).

Javascript is a language traditionally confined to a web browser with a limited global context defined mostly by what came to be known as the Document Object Model (DOM) level 0 (the Netscape Navigator Javascript API).

Server-side Javascript eliminates that restriction and allows Javascript to call into various pieces of native code (like the Postgres library) and open sockets.

Now require() is a special function call defined as part of the CommonJS spec. In node, it resolves libraries and modules in the Node search path, now usually defined as node_modules in the same directory (or the directory of the invoked javascript file) or the system-wide search path.

To try to answer the rest of your question, we need to use a proxy between the code running in the the browser and the database server.

Since we are discussing Node and you are already familiar with how to run a query from there, it would make sense to use Node as that proxy.

As a simple example, we're going to make a URL that returns a few facts about a Beatle, given a name, as JSON.

/* your connection code */

var express = require('express');
var app = express.createServer();
app.get('/beatles/:name', function(req, res) {
    var name = req.params.name || '';
    name = name.replace(/[^a-zA_Z]/, '');
    if (!name.length) {
        res.send({});
    } else {
        var query = client.query('SELECT * FROM BEATLES WHERE name =\''+name+'\' LIMIT 1');
        var data = {};
        query.on('row', function(row) {
            data = row;
            res.send(data);
        });
    };
});
app.listen(80, '127.0.0.1');

You should be able to do something like this:

byte[] bitmap = GetYourImage();

using(Image image = Image.FromStream(new MemoryStream(bitmap)))
{
    image.Save("output.jpg", ImageFormat.Jpeg);  // Or Png
}

Look here for more info.

Hopefully this helps.

puts false or true --> prints: false

puts false || true --> prints: true

Out-of-the-box solution to force JSON.stringify ignore timezones:

• Pure javascript (based on Anatoliy answer):

// Before: JSON.stringify apply timezone offset
const date =  new Date();
let string = JSON.stringify(date);
console.log(string);

// After: JSON.stringify keeps date as-is!

If you get this error in a context of creating ForeignKey relations between models. Example below raises AppRegistryNotReady: Models aren't loaded yet error.

from my_app.models import Workspace

workspace = models.ForeignKey(Workspace)

Then please try to reffer to a model as a string.

from my_app.models import Workspace

# One of these two lines might fix the problem.
workspace = models.ForeignKey('Workspace')
workspace = models.ForeignKey('my_app.Workspace')

Here is the Jquery Code

$(document).ready(function () {
     var el = $('#Container');
        var originalelpos = el.offset().top; // take it where it originally is on the page

        //run on scroll
        $(window).scroll(function () {
            var el = $('#Container'); // important! (local)
            var elpos = el.offset().top; // take current situation
            var windowpos = $(window).scrollTop();
            var finaldestination = windowpos + originalelpos;
            el.stop().animate({ 'top': finaldestination }, 1000);
        });
    });

I have tried all above solution but nothing work for me. after I have just add extend activity instead of AppCompatActivity and working fine.

used

public class MainActivity extends Activity  

instead of

public class MainActivity extends AppCompatActivity 

i dont know what real issue was that.

If you are using rest template, you can use this piece of code

    fun getClientHttpRequestFactory(): ClientHttpRequestFactory {
        val timeout = envTimeout.toInt()
        val config = RequestConfig.custom()
            .setConnectTimeout(timeout)
            .setConnectionRequestTimeout(timeout)
            .setSocketTimeout(timeout)
            .build()

        val acceptingTrustStrategy = TrustStrategy { chain: Array<X509Certificate?>?, authType: String? -> true }

        val sslContext: SSLContext = SSLContexts.custom()
            .loadTrustMaterial(null, acceptingTrustStrategy)
            .build()

        val csf = SSLConnectionSocketFactory(sslContext)

        val client = HttpClientBuilder
            .create()
            .setDefaultRequestConfig(config)
            .setSSLSocketFactory(csf)
            .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
            .build()
        return HttpComponentsClientHttpRequestFactory(client)
    }

    @Bean
    fun getRestTemplate(): RestTemplate {
        return RestTemplate(getClientHttpRequestFactory())
    }

Process p;
StringBuffer output = new StringBuffer();
try {
    p = Runtime.getRuntime().exec(params[0]);
    BufferedReader reader = new BufferedReader(
            new InputStreamReader(p.getInputStream()));
    String line = "";
    while ((line = reader.readLine()) != null) {
        output.append(line + "\n");
        p.waitFor();
    }
} 
catch (IOException e) {
    e.printStackTrace();
} catch (InterruptedException e) {
    e.printStackTrace();
}
String response = output.toString();
return response;

Why not just doing it this way?

DateTime dt1 = new DateTime(2009, 6, 1);
DateTime dt2 = DateTime.Now;
double totalminutes = (dt2 - dt1).TotalMinutes;

Hope this helps.

You check if it's null in C# like this:

if(MyObject != null) {
  //do something
}

If you want to check against default (tough to understand the question on the info given) check:

if(MyObject != default(MyObject)) {
 //do something
}

Download

Get the latest pre-built OpenCV for Android release from https://github.com/opencv/opencv/releases and unpack it (for example, opencv-4.4.0-android-sdk.zip).

Create an empty Android Studio project

Open Android Studio. Start a new project. 

Keep default target settings.

Use "Empty Activity" template. Name activity as MainActivity with a corresponding layout activity_main. Plug in your device and run the project. It should be installed and launched successfully before we'll go next.

 Add OpenCV dependency

Go to File->New->Import module

and provide a path to unpacked_OpenCV_package/sdk/java. The name of module detects automatically. Disable all features that Android Studio will suggest you on the next window.

Configure your library build.gradle (openCVLibrary build.gradle)

apply plugin: 'com.android.library'

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

Implement the library to the project (application build.gradle)

 implementation project(':openCVLibrary330')

We cannot always depend on ERRORLEVEL, because many times external programs or batch scripts do not return exit codes.

In that case we can use generic checks for failures like this:

IF EXIST %outfile% (DEL /F %outfile%)
CALL some_script.bat -o %outfile%
IF NOT EXIST %outfile%  (ECHO ERROR & EXIT /b)

And if the program outputs something to console, we can check it also.

some_program.exe 2>&1 | FIND "error message here" && (ECHO ERROR & EXIT /b)
some_program.exe 2>&1 | FIND "Done processing." || (ECHO ERROR & EXIT /b)

Just like @Dampes8N said:

$result = mysql_query($sql,$conecction);
$fp = fopen('file.csv', 'w');
while($row = mysql_fetch_assoc($result)){
    fputcsv($fp, $row);
}
fclose($fp);

Hope this helps.

Many string update functions in MySQL seems to be working like this: If one argument is null, then concatenation or other functions return null too. So, to update a field with null value, first set it to a non-null value, such as ''

For example:

update table set field='' where field is null;
update table set field=concat(field,' append');

You could do like this too.

<form action="ResultsDulith.php" id="intermediate" name="inputMachine[]" multiple="multiple" method="post">
    <select id="selectDuration" name="selectDuration[]" multiple="multiple"> 
        <option value="1 WEEK" >Last 1 Week</option>
        <option value="2 WEEK" >Last 2 Week </option>
        <option value="3 WEEK" >Last 3 Week</option>
         <option value="4 WEEK" >Last 4 Week</option>
          <option value="5 WEEK" >Last 5 Week</option>
           <option value="6 WEEK" >Last 6 Week</option>
    </select>
     <input type="submit"/> 
</form>

Then take the multiple selection from following PHP code below. It print the selected multiple values accordingly.

$shift=$_POST['selectDuration'];

print_r($shift);

If you want it based on the screen height, and not the window height:

const height = 0.7 * screen.height

// jQuery
$('.header').height(height)

// Vanilla JS
document.querySelector('.header').style.height = height + 'px'

// If you have multiple <div class="header"> elements
document.querySelectorAll('.header').forEach(function(node) {
  node.style.height = height + 'px'
})

I was trying to measure the time between events with the exception of what one entry that has multiple processes between the start and end. I needed this in the context of other single line processes.

I used a select with an inner join as my select statement within the Nth cte. The second cte I needed to extract the start date on X and end date on Y and used 1 as an id value to left join to put them on a single line.

Works for me, hope this helps.

cte_extract
as 
(
    select ps.Process as ProcessEvent
        , ps.ProcessStartDate 
        , ps.ProcessEndDate 
        -- select strt.*
    from dbo.tbl_some_table ps 
    inner join (select max(ProcessStatusId) ProcessStatusId 
                    from dbo.tbl_some_table 
                where Process = 'some_extract_tbl' 
                and convert(varchar(10), ProcessStartDate, 112) < '29991231'
                ) strt on strt.ProcessStatusId = ps.ProcessStatusID
), 
cte_rls
as 
(
    select 'Sample' as ProcessEvent, 
     x.ProcessStartDate, y.ProcessEndDate  from (
    select 1 as Id, ps.Process as ProcessEvent
        , ps.ProcessStartDate 
        , ps.ProcessEndDate
        -- select strt.*
    from dbo.tbl_some_table ps 
    inner join (select max(ProcessStatusId) ProcessStatusId 
                    from dbo.tbl_some_table 
                where Process = 'XX Prcss' 
                and convert(varchar(10), ProcessStartDate, 112) < '29991231'
                ) strt on strt.ProcessStatusId = ps.ProcessStatusID
    ) x
    left join (
        select 1 as Id, ps.Process as ProcessEvent
            , ps.ProcessStartDate 
            , ps.ProcessEndDate
            -- select strt.*
        from dbo.tbl_some_table ps 
        inner join (select max(ProcessStatusId) ProcessStatusId
                    from dbo.tbl_some_table 
                    where Process = 'YY Prcss Cmpltd' 
                    and convert(varchar(10), ProcessEndDate, 112) < '29991231'
                    ) enddt on enddt.ProcessStatusId = ps.ProcessStatusID
            ) y on y.Id = x.Id 
),

.... other ctes

Identifying the column is easy:

SELECT  *
FROM    ( SELECT    id,
                    time
          FROM      dbo.a
          UNION
          SELECT    id,
                    time
          FROM      dbo.b
        )
GROUP BY id

But it doesn't solve the main problem of this query: what's to be done with the second column values upon grouping by the first? Since (peculiarly!) you're using UNION rather than UNION ALL, you won't have entirely duplicated rows between the two subtables in the union, but you may still very well have several values of time for one value of the id, and you give no hint of what you want to do - min, max, avg, sum, or what?! The SQL engine should give an error because of that (though some such as mysql just pick a random-ish value out of the several, I believe sql-server is better than that).

So, for example, change the first line to SELECT id, MAX(time) or the like!

all answers are correct, but I want to mention that time delta accepts negative arguments.

I had the same issue. try this: copy to MemoryStream -> delete file -> download.

string absolutePath = "~/your path";
try {
    //copy to MemoryStream
    MemoryStream ms = new MemoryStream();
    using (FileStream fs = File.OpenRead(Server.MapPath(absolutePath))) 
    { 
        fs.CopyTo(ms); 
    }

    //Delete file
    if(File.Exists(Server.MapPath(absolutePath)))
       File.Delete(Server.MapPath(absolutePath))

    //Download file
    Response.Clear()
    Response.ContentType = "image/jpg";
    Response.AddHeader("Content-Disposition", "attachment;filename=\"" + absolutePath + "\"");
    Response.BinaryWrite(ms.ToArray())
}
catch {}

Response.End();

Could they make it any harder? Here's what I did: open system properties, click on advanced, add the environment variable, shut down visual studio and start it up again.

I have had a similar issue in iOS 8, 9 and 10 and the info above couldn't fix it, however I did discover a solution after a day of working on this. Granted it won't work for everyone but in my case my items were stacked in a column and had 0 height when it should have been content height. Switching the css to be row and wrap fixed the issue. This only works if you have a single item and they are stacked but since it took me a day to find this out I thought I should share my fix!

.wrapper {
    flex-direction: column; // <-- Remove this line
    flex-direction: row; // <-- replace it with
    flex-wrap: wrap; // <-- Add wrapping
}

.item {
    width: 100%;
}

np.save('data.npy', num_arr) # save
new_num_arr = np.load('data.npy') # load

Because the first option is already selected, the change event is never fired. Add an empty value as the first one and check for empty in the location assignment.

Here's an example:

https://jsfiddle.net/bL5sq/

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">_x000D_
  <option value="">Select...</option>_x000D_
  <option value="https://google.com">Google</option>_x000D_
  <option value="https://yahoo.com">Yahoo</option>_x000D_
</select>

By default, git will update execute file permissions if you change them. It will not change or track any other permissions.

If you don't see any changes when modifying execute permission, you probably have a configuration in git which ignore file mode.

Look into your project, in the .git folder for the config file and you should see something like this:

[core]
    filemode = false

You can either change it to true in your favorite text editor, or run:

git config core.filemode true

Then, you should be able to commit normally your files. It will only commit the permission changes.

The ".schema" commando will list available tables and their rows, by showing you the statement used to create said tables:

sqlite> create table_a (id int, a int, b int);
sqlite> .schema table_a
CREATE TABLE table_a (id int, a int, b int);

The definitive guide on how to use static, class or abstract methods in Python is one good link for this topic, and summary it as following.

@staticmethod function is nothing more than a function defined inside a class. It is callable without instantiating the class first. It’s definition is immutable via inheritance.

• Python does not have to instantiate a bound-method for object.
• It eases the readability of the code, and it does not depend on the state of object itself;

@classmethod function also callable without instantiating the class, but its definition follows Sub class, not Parent class, via inheritance, can be overridden by subclass. That’s because the first argument for @classmethod function must always be cls (class).

• Factory methods, that are used to create an instance for a class using for example some sort of pre-processing.
• Static methods calling static methods: if you split a static methods in several static methods, you shouldn't hard-code the class name but use class methods

If you're dealing with character encodings other than UTF-16, you shouldn't be using java.lang.String or the char primitive -- you should only be using byte[] arrays or ByteBuffer objects. Then, you can use java.nio.charset.Charset to convert between encodings:

Charset utf8charset = Charset.forName("UTF-8");
Charset iso88591charset = Charset.forName("ISO-8859-1");

ByteBuffer inputBuffer = ByteBuffer.wrap(new byte[]{(byte)0xC3, (byte)0xA2});

// decode UTF-8
CharBuffer data = utf8charset.decode(inputBuffer);

// encode ISO-8559-1
ByteBuffer outputBuffer = iso88591charset.encode(data);
byte[] outputData = outputBuffer.array();

I found that the cleanest way to do this is to create a custom TwigExtension and override its getGlobals() method. Rather than using $_SESSION, it's also better to use Symfony's Session class since it handles automatically starting/stopping the session.

I've got the following extension in /src/AppBundle/Twig/AppExtension.php:

<?php    
namespace AppBundle\Twig;

use Symfony\Component\HttpFoundation\Session\Session;

class AppExtension extends \Twig_Extension {

    public function getGlobals() {
        $session = new Session();
        return array(
            'session' => $session->all(),
        );
    }

    public function getName() {
        return 'app_extension';
    }
}

Then add this in /app/config/services.yml:

services:
    app.twig_extension:
        class: AppBundle\Twig\AppExtension
        public: false
        tags:
            - { name: twig.extension }

Then the session can be accessed from any view using:

{{ session.my_variable }}

Quick summary:

import "math/bits"
const (
    MaxUint uint = (1 << bits.UintSize) - 1
    MaxInt int = (1 << bits.UintSize) / 2 - 1
    MinInt int = (1 << bits.UintSize) / -2
)

Background:

As I presume you know, the uint type is the same size as either uint32 or uint64, depending on the platform you're on. Usually, one would use the unsized version of these only when there is no risk of coming close to the maximum value, as the version without a size specification can use the "native" type, depending on platform, which tends to be faster.

Note that it tends to be "faster" because using a non-native type sometimes requires additional math and bounds-checking to be performed by the processor, in order to emulate the larger or smaller integer. With that in mind, be aware that the performance of the processor (or compiler's optimised code) is almost always going to be better than adding your own bounds-checking code, so if there is any risk of it coming into play, it may make sense to simply use the fixed-size version, and let the optimised emulation handle any fallout from that.

With that having been said, there are still some situations where it is useful to know what you're working with.

The package "math/bits" contains the size of uint, in bits. To determine the maximum value, shift 1 by that many bits, minus 1. ie: (1 << bits.UintSize) - 1

Note that when calculating the maximum value of uint, you'll generally need to put it explicitly into a uint (or larger) variable, otherwise the compiler may fail, as it will default to attempting to assign that calculation into a signed int (where, as should be obvious, it would not fit), so:

const MaxUint uint = (1 << bits.UintSize) - 1

That's the direct answer to your question, but there are also a couple of related calculations you may be interested in.

According to the spec, uint and int are always the same size.

uint either 32 or 64 bits

int same size as uint

So we can also use this constant to determine the maximum value of int, by taking that same answer and dividing by 2 then subtracting 1. ie: (1 << bits.UintSize) / 2 - 1

And the minimum value of int, by shifting 1 by that many bits and dividing the result by -2. ie: (1 << bits.UintSize) / -2

In summary:

MaxUint: (1 << bits.UintSize) - 1

MaxInt: (1 << bits.UintSize) / 2 - 1

MinInt: (1 << bits.UintSize) / -2

full example (should be the same as below)

package main

import "fmt"
import "math"
import "math/bits"

func main() {
    var mi32 int64 = math.MinInt32
    var mi64 int64 = math.MinInt64

    var i32 uint64 = math.MaxInt32
    var ui32 uint64 = math.MaxUint32
    var i64 uint64 = math.MaxInt64
    var ui64 uint64 = math.MaxUint64
    var ui uint64 = (1 << bits.UintSize) - 1
    var i uint64 = (1 << bits.UintSize) / 2 - 1
    var mi int64 = (1 << bits.UintSize) / -2

    fmt.Printf(" MinInt32: %d\n", mi32)
    fmt.Printf(" MaxInt32:  %d\n", i32)
    fmt.Printf("MaxUint32:  %d\n", ui32)
    fmt.Printf(" MinInt64: %d\n", mi64)

Adding autocomplete="new-password" to the password field did the trick. Removed auto filling of both user name and password fields in Chrome.

<input type="password" name="whatever" autocomplete="new-password" />

Every command that runs has an exit status.

That check is looking at the exit status of the command that finished most recently before that line runs.

If you want your script to exit when that test returns true (the previous command failed) then you put exit 1 (or whatever) inside that if block after the echo.

That being said if you are running the command and wanting to test its output using the following is often more straight-forward.

if some_command; then
    echo command returned true
else
    echo command returned some error
fi

Or to turn that around use ! for negation

if ! some_command; then
    echo command returned some error
else
    echo command returned true
fi

Note though that neither of those cares what the error code is. If you know you only care about a specific error code then you need to check $? manually.

This is only possible with setting a http response header by the server side code. Namely;

Content-Disposition: attachment; filename=fname.ext

I am running PHP version 5.4 on shared hosting and both of these both successfully return the same results:

php_uname('n');

gethostname();

Run cmd and then run node server.js. In your example, you are trying to use the REPL to run your command, which is not going to work. The ellipsis is node.js expecting more tokens before closing the current scope (you can type code in and run it on the fly here)

You can use axis:

> axis(side=1, at=c(0:23))

That is, something like this:

plot(0:23, d, type='b', axes=FALSE)
axis(side=1, at=c(0:23))
axis(side=2, at=seq(0, 600, by=100))
box()

getElementById is defined by DOM Level 1 HTML to return null in the case no element is matched.

!==null is the most explicit form of the check, and probably the best, but there is no non-null falsy value that getElementById can return - you can only get null or an always-truthy Element object. So there's no practical difference here between !==null, !=null or the looser if (document.getElementById('xx')).

Sieve of Eratosthenes. its bit look but its simple and it works!

function count_prime(arg) {

    arg = typeof arg !== 'undefined' ? arg : 20; //default value
    var list = [2]
    var list2 = [0,1]
    var real_prime = []

    counter = 2
    while (counter < arg ) {
        if (counter % 2 !== 0) {
            list.push(counter)
        }
        counter++
    }

    for (i = 0; i < list.length - 1; i++) {
        var a = list[i]
        for (j = 0; j < list.length - 1; j++) {
            if (list[j] % a === 0 && list[j] !== a) {
                list[j] = false;       // assign false to non-prime numbers
            }
        }
        if (list[i] !== false) { 
            real_prime.push(list[i]);  // save all prime numbers in new array
        }
    }
 }
window.onload=count_prime(100);

It has a slightly different pattern which is (I think) what you are looking for:

try {
  mutex.acquire();
  try {
    // do something
  } finally {
    mutex.release();
  }
} catch(InterruptedException ie) {
  // ...
}

In this usage, you're only calling release() after a successful acquire()

I think transactions belong on the Service layer. It's the one that knows about units of work and use cases. It's the right answer if you have several DAOs injected into a Service that need to work together in a single transaction.

You can do it easily by Assertion using Selenium Testng framework.

Steps:

1.Create Firefox browser session

2.Initialize expected title name.

3.Navigate to "www.google.com" [As per you requirement, you can change] and wait for some time (15 seconds) to load the page completely.

4.Get the actual title name using "driver.getTitle()" and store it in String variable.

5.Apply the Assertion like below, Assert.assertTrue(actualGooglePageTitlte.equalsIgnoreCase(expectedGooglePageTitle ),"Page title name not matched or Problem in loading grid");

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.Assert;
import org.testng.annotations.Test;
import com.myapplication.Utilty;

public class PageTitleVerification
{   
private static WebDriver driver = new FirefoxDriver();

@Test
public void test01_GooglePageTitleVerify()
{               
driver.navigate().to("https://www.google.com/");
String expectedGooglePageTitle = "Google";      
Utility.waitForElementInDOM(driver, "Google Search", 15);   
//Get page title
String actualGooglePageTitlte=driver.getTitle();
System.out.println("Google page title" + actualGooglePageTitlte);   
//Verify expected page title and actual page title is same  
Assert.assertTrue(actualGooglePageTitlte.equalsIgnoreCase(expectedGooglePageTitle 
),"Page title not matched or Problem in loading url page");     
}
}

import org.openqa.selenium.By;
import org.openqa.selenium.NoSuchElementException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;

public class Utility {

/*Wait for an element to be present in DOM before specified time (in seconds ) has 
elapsed */
public static void waitForElementInDOM(WebDriver driver,String elementIdentifier, 
long timeOutInSeconds) 
{       
WebDriverWait wait = new WebDriverWait(driver, timeOutInSeconds );
try
{
//this will wait for element to be visible for 15 seconds        
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath
(elementIdentifier))); 
}
catch(NoSuchElementException e)
{           
e.printStackTrace();
}           
}
}

If you guys are looking for a solution for Android, you can use the following code to get the epoch seconds from the timestamp string.

public static long timestampToEpochSeconds(String srcTimestamp) {
    long epoch = 0;

    try {
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            Instant instant = Instant.parse(srcTimestamp);
            epoch = instant.getEpochSecond();
        } else {
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ss.SSSSSS'Z'", Locale.getDefault());
            sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
            Date date = sdf.parse(srcTimestamp);
            if (date != null) {
                epoch = date.getTime() / 1000;
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    return epoch;
}

Sample input: 2019-10-15T05:51:31.537979Z

Sample output: 1571128673

Finally I got it to work. Steve's answer is right but not for all cases. It fails when that view is being executed from a third schema. For that to work you have to add the grant option:

GRANT SELECT ON [TABLE_NAME] TO [READ_USERNAME] WITH GRANT OPTION;

That way, [READ_USERNAME] can also grant select privilege over the view to another schema

You can add the directories for your build process like:

    ...
   <resources>
     <resource>
       <directory>src/bootstrap</directory>
     </resource>
   </resources>
   ...

The src/main/java is the default path which is not needed to be mentioned in the pom.xml

How about simply (Please note, come up with a better name for the class name this is simply an example):

.centerText{
   text-align: center;
}


<div>
   <table style="width:100%">
   <tbody>
   <tr>
      <td class="centerText">Cell 1</td>
      <td>Cell 2</td>
    </tr>
    <tr>
      <td class="centerText">Cell 3</td>
      <td>Cell 4</td>
    </tr>
    </tbody>
    </table>
</div>

Example here

You can place the css in a separate file, which is recommended. In my example, I created a file called styles.css and placed my css rules in it. Then include it in the html document in the <head> section as follows:

<head>
    <link href="styles.css" rel="stylesheet" type="text/css">
</head>

The alternative, not creating a seperate css file, not recommended at all... Create <style> block in your <head> in the html document. Then just place your rules there.

<head>
 <style type="text/css">
   .centerText{
       text-align: center;
    }
 </style>
</head>

ActiveRecord stores validation errors in an array called errors. If you have a User model then you would access the validation errors in a given instance like so:

@user = User.create[params[:user]] # create will automatically call validators

if @user.errors.any? # If there are errors, do something

  # You can iterate through all messages by attribute type and validation message
  # This will be something like:
  # attribute = 'name'
  # message = 'cannot be left blank'
  @user.errors.each do |attribute, message|
    # do stuff for each error
  end

  # Or if you prefer, you can get the full message in single string, like so:
  # message = 'Name cannot be left blank'
  @users.errors.full_messages.each do |message|
    # do stuff for each error
  end

  # To get all errors associated with a single attribute, do the following:
  if @user.errors.include?(:name)
    name_errors = @user.errors[:name]

    if name_errors.kind_of?(Array)
      name_errors.each do |error|
        # do stuff for each error on the name attribute
      end
    else
      error = name_errors
      # do stuff for the one error on the name attribute.
    end
  end
end

Of course you can also do any of this in the views instead of the controller, should you want to just display the first error to the user or something.

In my case I was doing show / hide elements of a form according to whether an input element was empty or not, so that when hiding the elements the element following the hidden ones was repositioned occupying its space it was necessary to do a float: left of the element of such an element. Even using a plugin as dependsOn it was necessary to use float.

If you bind events to the onmouseover and onmouseout events in Jquery, you can then trigger that effect using mouseenter().

Many people in the Vim community argue that you should not navigate in Insert mode, that it is not the Vim way. I think this is an incorrect sentiment learned when transitioning from standard editors to Vim.

Vim is most powerful when you use its tools to create atomic, repeatable actions or finds.

It is ok to navigate while in Insert mode if you are fixing a mistake you made in the same Insert session. You should not navigate outside of the range of text you modified.

If you make a mistake while entering text and escape out of Insert mode to fix it you will not be able to repeat the intended action, . will repeat the correction.

Vim does support many Insert mode navigation keys. Obviously there are the arrow keys, Home, and End, but there are also many other shortcuts. See :h ins-special-keys.

Yes, you can reference any image from the image element. And you can use data URIs to make the SVG self-contained. An example:

<svg xmlns="http://www.w3.org/2000/svg"
     xmlns:xlink="http://www.w3.org/1999/xlink">

    ...
    <image
        width="100" height="100"
        xlink:href="data:image/png;base64,IMAGE_DATA"
        />
    ...
</svg>

The svg element attribute xmlns:xlink declares xlink as a namespace prefix and says where the definition is. That then allows the SVG reader to know what xlink:href means.

The IMAGE_DATA is where you'd add the image data as base64-encoded text. Vector graphics editors that support SVG usually have an option for saving with images embedded. Otherwise there are plenty of tools around for encoding a byte stream to and from base64.

Here's a full example from the SVG testsuite.

cat(capture.output(print(my.list), file="test.txt"))

from R: Export and import a list to .txt file https://stackoverflow.com/users/1855677/42 is the only thing that worked for me. This outputs the list of lists as it is in the text file

Why don't you just make it easy and simple. If I need to know the number of days between today and say, March 10th, 2015, I can just enter the simple formula.

Lets say the static date is March 10th, 2015, and is in cell O5.

The formula to determine the number of days between today and O5 would be, =O5-Today()

Nothing fancy or DATEDIF stuff. Obviously, the cell where you type this formula in must have a data type of 'number'. Just type your date in normally in the reference cell, in this case O5.

The problem is that simple console can't edit the registry. No need to edit the registry by hand, just launch the groovysh once with administrative priveleges. All subsequent launches work without error.

Adding "-EA Stop" solved this for me.

In MacOS Catalina 10.15.5 the .npmrc file path can be found at

/Users/<user-name>/.npmrc

Open in it in (for first time users, create a new file) any editor and copy-paste your token. Save it.

You are ready to go.

Note: As mentioned by @oligofren, the command npm config ls -l will npm configurations. You will get the .npmrc file from config parameter userconfig

Change the theme in your manifest.

If you want to hide nav bar for one activity you can use this:

<activity
        android:name="Activity Name"
        android:theme="@android:style/Theme.Black.NoTitleBar"
        android:label="@string/app_name" >

If you want to hide nav bar for entire application you can use this:

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@android:style/Theme.Black.NoTitleBar" >

You can check if the row exists, and then INSERT or UPDATE, but this guarantees you will be performing two SQL operations instead of one:

1. check if row exists
2. insert or update row

A better solution is to always UPDATE first, and if no rows were updated, then do an INSERT, like so:

update table1 
set name = 'val2', itemname = 'val3', itemcatName = 'val4', itemQty = 'val5'
where id = 'val1'

if @@ROWCOUNT = 0
  insert into table1(id, name, itemname, itemcatName, itemQty)
  values('val1', 'val2', 'val3', 'val4', 'val5')

This will either take one SQL operations, or two SQL operations, depending on whether the row already exists.

But if performance is really an issue, then you need to figure out if the operations are more likely to be INSERT's or UPDATE's. If UPDATE's are more common, do the above. If INSERT's are more common, you can do that in reverse, but you have to add error handling.

BEGIN TRY
  insert into table1(id, name, itemname, itemcatName, itemQty)
  values('val1', 'val2', 'val3', 'val4', 'val5')
END TRY
BEGIN CATCH
  update table1 
  set name = 'val2', itemname = 'val3', itemcatName = 'val4', itemQty = 'val5'
  where id = 'val1'
END CATCH

To be really certain if you need to do an UPDATE or INSERT, you have to do two operations within a single TRANSACTION. Theoretically, right after the first UPDATE or INSERT (or even the EXISTS check), but before the next INSERT/UPDATE statement, the database could have changed, causing the second statement to fail anyway. This is exceedingly rare, and the overhead for transactions may not be worth it.

Alternately, you can use a single SQL operation called MERGE to perform either an INSERT or an UPDATE, but that's also probably overkill for this one-row operation.

Consider reading about SQL transaction statements, race conditions, SQL MERGE statement.

use this to get String

String res = response.body().string();

instead of

String res = response.body().toString();

and always keep a check for null before converting responsebody to string

if(response.body() != null){
     //do your stuff   
}

I could not find a easy way to set the margin for a single page.

My solution was to use vspace with the number of centimeters of empty space I wanted:

 \vspace*{5cm}                                                             

I put this command at the beginning of the pages that I wanted to have +5cm of margin.

The point against parseInt-approach:

There's no need to use lambdas and/or give radix parameter to parseInt, just use parseFloat or Number instead.

Reasons:

1. It's working:

   var src = "1,2,5,4,3";
   var ids = src.split(',').map(parseFloat); // [1, 2, 5, 4, 3]
   
   var obj = {1: ..., 3: ..., 4: ..., 7: ...};
   var keys= Object.keys(obj); // ["1", "3", "4", "7"]
   var ids = keys.map(parseFloat); // [1, 3, 4, 7]
   
   var arr = ["1", 5, "7", 11];
   var ints= arr.map(parseFloat); // [1, 5, 7, 11]
   ints[1] === "5" // false
   ints[1] === 5   // true
   ints[2] === "7" // false
   ints[2] === 7   // true
   

2. It's shorter.

3. It's a tiny bit quickier and takes advantage of cache, when parseInt-approach - doesn't:

     // execution time measure function
     // keep it simple, yeah?
   > var f = (function (arr, c, n, m) {
         var i,t,m,s=n();
         for(i=0;i++<c;)t=arr.map(m);
         return n()-s
     }).bind(null, "2,4,6,8,0,9,7,5,3,1".split(','), 1000000, Date.now);
   
   > f(Number) // first launch, just warming-up cache
   > 3971 // nice =)
   
   > f(Number)
   > 3964 // still the same
   
   > f(function(e){return+e})
   > 5132 // yup, just little bit slower
   
   > f(function(e){return+e})
   > 5112 // second run... and ok.
   
   > f(parseFloat)
   > 3727 // little bit quicker than .map(Number)
   
   > f(parseFloat)
   > 3737 // all ok
   
   > f(function(e){return parseInt(e,10)})
   > 21852 // awww, how adorable...
   
   > f(function(e){return parseInt(e)})
   > 22928 // maybe, without '10'?.. nope.
   
   > f(function(e){return parseInt(e)})
   > 22769 // second run... and nothing changes.
   
   > f(Number)
   > 3873 // and again
   > f(parseFloat)
   > 3583 // and again
   > f(function(e){return+e})
   > 4967 // and again
   
   > f(function(e){return parseInt(e,10)})
   > 21649 // dammit 'parseInt'! >_<
   

Notice: In Firefox parseInt works about 4 times faster, but still slower than others. In total: +e < Number < parseFloat < parseInt

In my opinion it would be better to keep the logic in the controller and pass it to the view to use. This can be done one of two ways using the 'View::make' method. I am currently using Laravel 3 but I am pretty sure that it is the same way in Laravel 4.

public function action_hello($userName)
{
    return View::make('hello')->with('name', $userName);
}

or

public function action_hello($first, $last)
{
    $data = array(
        'forename'  => $first,
        'surname' => $last
    );
    return View::make('hello', $data);
}

The 'with' method is chainable. You would then use the above like so:

<p>Hello {{$name}}</p>

One thing to be aware of, is that isVisible() returns the visible state of the current fragment. There is a problem in the support library, where if you have nested fragments, and you hide the parent fragment (and therefore all the children), the child still says it is visible.

isVisible() is final, so can't override unfortunately. My workaround was to create a BaseFragment class that all my fragments extend, and then create a method like so:

public boolean getIsVisible()
{
    if (getParentFragment() != null && getParentFragment() instanceof BaseFragment)
    {
        return isVisible() && ((BaseFragment) getParentFragment()).getIsVisible();
    }
    else
    {
        return isVisible();
    }
}

I do isVisible() && ((BaseFragment) getParentFragment()).getIsVisible(); because we want to return false if any of the parent fragments are hidden.

This seems to do the trick for me.

Consider a table with id tbl: the jQuery code would be:

$('#tbl tr:not(:first)').remove();

Use beginUpdates and endUpdates to insert a new cell when the button clicked.

As @vadian said in comment, begin/endUpdates has no effect for a single insert/delete/move operation

First of all, append data in your tableview array

Yourarray.append([labeltext])  

Then update your table and insert a new row

// Update Table Data
tblname.beginUpdates()
tblname.insertRowsAtIndexPaths([
NSIndexPath(forRow: Yourarray.count-1, inSection: 0)], withRowAnimation: .Automatic)
tblname.endUpdates()

This inserts cell and doesn't need to reload the whole table but if you get any problem with this, you can also use tableview.reloadData()

Swift 3.0

tableView.beginUpdates()
tableView.insertRows(at: [IndexPath(row: yourArray.count-1, section: 0)], with: .automatic)
tableView.endUpdates()

Objective-C

[self.tblname beginUpdates];
NSArray *arr = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:Yourarray.count-1 inSection:0]];
[self.tblname insertRowsAtIndexPaths:arr withRowAnimation:UITableViewRowAnimationAutomatic];
[self.tblname endUpdates];

Here is a solution that can help you dump all the logs onto a text file

adb logcat -d > logs.txt

For me solution was not to use mkvirtualenv, but:

python -m venv path/to/your/virtualenv

workon works correctly.

while in virtualenv: pip -V shows virtualenv's path to pip

Time to go back in time for a lesson. While we don't think about these things much in our fancy managed languages today, they are built on the same foundation, so let's look at how memory is managed in C.

Before I dive in, a quick explanation of what the term "pointer" means. A pointer is simply a variable that "points" to a location in memory. It doesn't contain the actual value at this area of memory, it contains the memory address to it. Think of a block of memory as a mailbox. The pointer would be the address to that mailbox.

In C, an array is simply a pointer with an offset, the offset specifies how far in memory to look. This provides O(1) access time.

  MyArray   [5]
     ^       ^
  Pointer  Offset

All other data structures either build upon this, or do not use adjacent memory for storage, resulting in poor random access look up time (Though there are other benefits to not using sequential memory).

For example, let's say we have an array with 6 numbers (6,4,2,3,1,5) in it, in memory it would look like this:

=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================

In an array, we know that each element is next to each other in memory. A C array (Called MyArray here) is simply a pointer to the first element:

=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================
   ^
MyArray

If we wanted to look up MyArray[4], internally it would be accessed like this:

   0     1     2     3     4 
=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================
                           ^
MyArray + 4 ---------------/
(Pointer + Offset)

Because we can directly access any element in the array by adding the offset to the pointer, we can look up any element in the same amount of time, regardless of the size of the array. This means that getting MyArray[1000] would take the same amount of time as getting MyArray[5].

An alternative data structure is a linked list. This is a linear list of pointers, each pointing to the next node

========    ========    ========    ========    ========
| Data |    | Data |    | Data |    | Data |    | Data |
|      | -> |      | -> |      | -> |      | -> |      | 
|  P1  |    |  P2  |    |  P3  |    |  P4  |    |  P5  |        
========    ========    ========    ========    ========

P(X) stands for Pointer to next node.

Note that I made each "node" into its own block. This is because they are not guaranteed to be (and most likely won't be) adjacent in memory.

If I want to access P3, I can't directly access it, because I don't know where it is in memory. All I know is where the root (P1) is, so instead I have to start at P1, and follow each pointer to the desired node.

This is a O(N) look up time (The look up cost increases as each element is added). It is much more expensive to get to P1000 compared to getting to P4.

Higher level data structures, such as hashtables, stacks and queues, all may use an array (or multiple arrays) internally, while Linked Lists and Binary Trees usually use nodes and pointers.

You might wonder why anyone would use a data structure that requires linear traversal to look up a value instead of just using an array, but they have their uses.

Take our array again. This time, I want to find the array element that holds the value '5'.

=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================
   ^     ^     ^     ^     ^   FOUND!

In this situation, I don't know what offset to add to the pointer to find it, so I have to start at 0, and work my way up until I find it. This means I have to perform 6 checks.

Because of this, searching for a value in an array is considered O(N). The cost of searching increases as the array gets larger.

Remember up above where I said that sometimes using a non sequential data structure can have advantages? Searching for data is one of these advantages and one of the best examples is the Binary Tree.

A Binary Tree is a data structure similar to a linked list, however instead of linking to a single node, each node can link to two children nodes.

         ==========
         |  Root  |         
         ==========
        /          \ 
  =========       =========
  | Child |       | Child |
  =========       =========
                  /       \
            =========    =========
            | Child |    | Child |
            =========    =========

 Assume that each connector is really a Pointer

When data is inserted into a binary tree, it uses several rules to decide where to place the new node. The basic concept is that if the new value is greater than the parents, it inserts it to the left, if it is lower, it inserts it to the right.

This means that the values in a binary tree could look like this:

         ==========
         |   100  |         
         ==========
        /          \ 
  =========       =========
  |  200  |       |   50  |
  =========       =========
                  /       \
            =========    =========
            |   75  |    |   25  |
            =========    =========

When searching a binary tree for the value of 75, we only need to visit 3 nodes ( O(log N) ) because of this structure:

• Is 75 less than 100? Look at Right Node
• Is 75 greater than 50? Look at Left Node
• There is the 75!

Even though there are 5 nodes in our tree, we did not need to look at the remaining two, because we knew that they (and their children) could not possibly contain the value we were looking for. This gives us a search time that at worst case means we have to visit every node, but in the best case we only have to visit a small portion of the nodes.

That is where arrays get beat, they provide a linear O(N) search time, despite O(1) access time.

This is an incredibly high level overview on data structures in memory, skipping over a lot of details, but hopefully it illustrates an array's strength and weakness compared to other data structures.

To compare each item with the next one in an iterator without instantiating a list:

import itertools
it = (x for x in range(10))
data1, data2 = itertools.tee(it)
data2.next()
for a, b in itertools.izip(data1, data2):
  print a, b

I have achieved this with the help of Attribute Routing in MVC5. Admittedly I am new to MVC coming from a decade of web development using WebForms, but the following has worked for me. Unlike the accepted answer this allows all the overloaded actions to be rendered by the same view file.

First enable Attribute Routing in App_Start/RouteConfig.cs.

public class RouteConfig
{
    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapMvcAttributeRoutes();

        routes.MapRoute(
            name: "Default",
            url: "{controller}/{action}/{id}",
            defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
        );            
    }
}

Optionally decorate your controller class with a default route prefix.

[RoutePrefix("Returns")]
public class ReturnsController : BaseController
{
    //.......

Then decorate your controller actions that overload each other with a common route and parameters to suit. Using type constrained parameters you can use the same URI format with IDs of different types.

[HttpGet]
// Returns
public ActionResult Index()
{
    //.....
}

[HttpGet]
[Route("View")]
// Returns/View
public ActionResult View()
{
    // I wouldn't really do this but it proves the concept.
    int id = 7026;
    return View(id);
}

[HttpGet]
[Route("View/{id:int}")]
// Returns/View/7003
public ActionResult View(int id)
{
    //.....
}

[HttpGet]
[Route("View/{id:Guid}")]
// Returns/View/99300046-0ba4-47db-81bf-ba6e3ac3cf01
public ActionResult View(Guid id)
{
    //.....
}

Hope this helps and is not leading somebody down the wrong path. :-)

Check if you have all NLTK libraries.

Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.

You have to nest the requests:

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   obj = name;   // sID is only now available!   sID = obj.id;   console.log(sID); }); 

• Put the second request into a function
• and let it accept sID as a parameter, so you don't have to declare it globally anymore! (Global variables are almost always evil!)
• Remove sID and obj variables - name.id is sufficient unless you really need the other variables outside the function.

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   // We don't need sID or obj here - name.id is sufficient   console.log(name.id);    doSecondRequest(name.id); });  /// TODO Choose a better name function doSecondRequest(sID) {   $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){         console.log(stats);   }); } 

Hapy New Year :)

Open $CATALINA_BASE/conf/web.xml and find this

<!-- ==================== Default Session Configuration ================= -->
<!-- You can set the default session timeout (in minutes) for all newly   -->
<!-- created sessions by modifying the value below.                       -->

<session-config>
  <session-timeout>30</session-timeout>
</session-config>

all webapps implicitly inherit from this default web descriptor. You can override session-config as well as other settings defined there in your web.xml.

This is actually from my Tomcat 7 (Windows) but I think 5.5 conf is not very different

I just had need to do this for a config file.

var config = {
    x: "CHANGE_ME",
    y: "CHANGE_ME",
    z: "CHANGE_ME"
}

export default config;

You can do it like this

import { default as config } from "./config";

console.log(config.x); // CHANGE_ME

This is using Typescript mind you.

Try Facetype.js, you convert your .TTF font into a Javascript file. Full SEO compatible, supports FF, IE6 and Safari and degrades gracefully on other browsers.

Create a new "Empty Project" , Add your Cpp file to the new project, delete the line that includes stdafx.

Done.

The project no longer needs the stdafx. It is added automatically when you create projects with installed templates.

java.lang.UnsupportedOperationException

Thrown to indicate that the requested operation is not supported.

Here is a somewhat kludgy way to do it that works with GO-batches, by using a "global" variable.

if object_id('tempdb..#vars') is not null
begin
  drop table #vars
end

create table #vars (continueScript bit)
set nocount on
  insert #vars values (1)
set nocount off

-- Start of first batch
if ((select continueScript from #vars)=1) begin

  print '1'

  -- Conditionally terminate entire script
  if (1=1) begin
    set nocount on
      update #vars set continueScript=0
    set nocount off
    return
  end

end
go

-- Start of second batch
if ((select continueScript from #vars)=1) begin

  print '2'

end
go

And here is the same idea used with a transaction and a try/catch block for each GO-batch. You can try to change the various conditions and/or let it generate an error (divide by 0, see comments) to test how it behaves:

if object_id('tempdb..#vars') is not null
begin
  drop table #vars
end

create table #vars (continueScript bit)
set nocount on
  insert #vars values (1)
set nocount off

begin transaction;
  -- Batch 1 starts here
  if ((select continueScript from #vars)=1) begin
    begin try 
      print 'batch 1 starts'

      if (1=0) begin
        print 'Script is terminating because of special condition 1.'
        set nocount on
          update #vars set continueScript=0
        set nocount off
        return
      end

      print 'batch 1 in the middle of its progress'

      if (1=0) begin
        print 'Script is terminating because of special condition 2.'
        set nocount on
          update #vars set continueScript=0
        set nocount off
        return
      end

      set nocount on
        -- use 1/0 to generate an exception here
        select 1/1 as test
      set nocount off

    end try
    begin catch
      set nocount on
        select 
          error_number() as errornumber

        update #vars set continueScript=0
      set nocount off
      return
    end catch;

  end
  go

  -- Batch 2 starts here
  if ((select continueScript from #vars)=1) begin

    begin try

I lately came up with this error. But it was even more odd. I was working on Android N and everything was going smoothly OK, until I test it on JellyBeans and Lollipop. In which I kept on getting the same DB error.

android.database.sqlite.SQLiteCantOpenDatabaseException: unknown error (code 14): Could not open database 06-10 23:07:03.641: E/SQLiteDatabase(4419):

I had the right permissions in my manifest, including:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

The problem was this line in my DataBaseHelper.java:

private static String DB_PATH = "/data/data/com.example.quotes/databases";

which needed to be loaded from the context this way:

String DB_PATH = getContext().getApplicationInfo().dataDir+"/databases/";

Now is working properly form SDK 17.

Have you looked into using a HorizontalScrollView to wrap your list items? That will allow each of your list items to be horizontally scrollable (what you put in there is up to you, and can make them dynamic items similar to ListView). This will work well if you are only after a single row of items.

You can install directly from the repository (note the type="source"):

install.packages("RJSONIO", repos = "http://www.omegahat.org/R", type="source")

Try with this :

jQuery('#main').css({ opacity: 0.6 });

Try This:

            $.ajax({
                    url:"",
                    type: "POST",
                    data: new FormData($('#uploadDatabaseForm')[0]),
                    contentType:false,
                    cache: false,
                    processData:false,
                    success:function (msg) {}
                  });

You can drop the range(len()):

weights_h = [[random.random() for e in inputs[0]] for e in range(hiden_neurons)]

But really, you should probably use numpy.

In [9]: numpy.random.random((3, 3))
Out[9]:
array([[ 0.37052381,  0.03463207,  0.10669077],
       [ 0.05862909,  0.8515325 ,  0.79809676],
       [ 0.43203632,  0.54633635,  0.09076408]])

Since there are several answers here showing non-working code for Windows, here is a clarification:

Runtime.getRuntime().exec("cls");

This command does not work, for two reasons:

1. There is no executable named cls.exe or cls.com in a standard Windows installation that could be invoked via Runtime.exec, as the well-known command cls is builtin to Windows’ command line interpreter.

2. When launching a new process via Runtime.exec, the standard output gets redirected to a pipe which the initiating Java process can read. But when the output of the cls command gets redirected, it doesn’t clear the console.

To solve this problem, we have to invoke the command line interpreter (cmd) and tell it to execute a command (/c cls) which allows invoking builtin commands. Further we have to directly connect its output channel to the Java process’ output channel, which works starting with Java 7, using inheritIO():

import java.io.IOException;

public class CLS {
    public static void main(String... arg) throws IOException, InterruptedException {
        new ProcessBuilder("cmd", "/c", "cls").inheritIO().start().waitFor();
    }
}

Now when the Java process is connected to a console, i.e. has been started from a command line without output redirection, it will clear the console.

It's important to point out that all of the above solutions map the port to every interface on your machine. This is less than desirable if you have a public IP address, or your machine has an IP on a large network. Your application may be exposed to a much wider audience than you'd hoped.

    dockerfile: Dockerfile-redis
    ports:
    - "127.0.0.1:3901:3901"

127.0.0.1 is the ip address that maps to the hostname localhost on your machine. So now your application is only exposed over that interface and since 127.0.0.1 is only accessible via your machine, you're not exposing your containers to the entire world.

The documentation explains this further and can be found here: https://docs.docker.com/compose/compose-file/#ports

Note: If you're using Docker for mac this will make the container listen on 127.0.0.1 on the Docker for Mac VM and will not be accessible from your localhost. If I recall correctly.

If you're using Python 3, or appropriate Python 2.x version with from __future__ import print_function then:

data = [7, 7, 7, 7]
print(*data, sep='')

Otherwise, you'll need to convert to string and print:

print ''.join(map(str, data))

When doing django ranges with a filter make sure you know the difference between using a date object vs a datetime object. __range is inclusive on dates but if you use a datetime object for the end date it will not include the entries for that day if the time is not set.

    startdate = date.today()
    enddate = startdate + timedelta(days=6)
    Sample.objects.filter(date__range=[startdate, enddate])

returns all entries from startdate to enddate including entries on those dates. Bad example since this is returning entries a week into the future, but you get the drift.

    startdate = datetime.today()
    enddate = startdate + timedelta(days=6)
    Sample.objects.filter(date__range=[startdate, enddate])

will be missing 24 hours worth of entries depending on what the time for the date fields is set to.

You have to use either DQL or the QueryBuilder. E.g. in your Purchase-EntityRepository you could do something like this:

$q = $this->createQueryBuilder('p')
          ->where('p.prize > :purchasePrize')
          ->setParameter('purchasePrize', 200)
          ->getQuery();

$q->getResult();

For even more complex scenarios take a look at the Expr() class.

Taken from jQuery docs:

var arr = [ "one", "two", "three", "four", "five" ];
var obj = { one:1, two:2, three:3, four:4, five:5 };

jQuery.each(arr, function() {
  $("#" + this).text("My id is " + this + ".");
  return (this != "four"); // will stop running to skip "five"
});

jQuery.each(obj, function(i, val) {
  $("#" + i).append(document.createTextNode(" - " + val));
});

I got the same issue in IntelliJ IDEA Community with Maven and I had to reimport the project by right-clicking the project in the Project tab -> Maven -> Reimport

I find this easier.

sort -u input_filename > output_filename

-u stands for unique.

The C++ standard requires a definition for your static const member if the definition is somehow needed.

The definition is required, for example if it's address is used. push_back takes its parameter by const reference, and so strictly the compiler needs the address of your member and you need to define it in the namespace.

When you explicitly cast the constant, you're creating a temporary and it's this temporary which is bound to the reference (under special rules in the standard).

This is a really interesting case, and I actually think it's worth raising an issue so that the std be changed to have the same behaviour for your constant member!

Although, in a weird kind of way this could be seen as a legitimate use of the unary '+' operator. Basically the result of the unary + is an rvalue and so the rules for binding of rvalues to const references apply and we don't use the address of our static const member:

v.push_back( +Foo::MEMBER );

CTRL - ML toggles line numbers in the CodeMirror area. See the QuickHelp for other keyboard shortcuts.

In more details CTRL - M (or ESC) bring you to command mode, then pressing the L keys should toggle the visibility of current cell line numbers. In more recent notebook versions Shift-L should toggle for all cells.

If you can't remember the shortcut, bring up the command palette Ctrl-Shift+P (Cmd+Shift+P on Mac), and search for "line numbers"), it should allow to toggle and show you the shortcut.

The two functions below I have found to be very useful when dealing with many variable testing cases.

def nz(value, none_value, strict=True):
    ''' This function is named after an old VBA function. It returns a default
        value if the passed in value is None. If strict is False it will
        treat an empty string as None as well.

        example:
        x = None
        nz(x,"hello")
        --> "hello"
        nz(x,"")
        --> ""
        y = ""   
        nz(y,"hello")
        --> ""
        nz(y,"hello", False)
        --> "hello" '''

    if value is None and strict:
        return_val = none_value
    elif strict and value is not None:
        return_val = value
    elif not strict and not is_not_null(value):
        return_val = none_value
    else:
        return_val = value
    return return_val 

def is_not_null(value):
    ''' test for None and empty string '''
    return value is not None and len(str(value)) > 0
