nl2br() worked for me, but I needed to wrap the variable with double quotes:

This works:

$description = nl2br("$description");

This doesn't work:

$description = nl2br($description);

<select name="FakeName" id="Fake-ID" aria-required="true" required>  <?php $options=nl2br(file_get_contents("employees.txt")); $options=explode("<br />",$options);  foreach ($options as $item_array) { echo "<option value='".$item_array"'>".$item_array"</option>";  } ?> </select> 

Something a bit more functional (easy to use anywhere):

function strip_carriage_returns($string)
{
    return str_replace(array("\n\r", "\n", "\r"), '', $string);
}

Using PHP_EOL as the search replacement parameter is also a good idea! Kudos.

<?php
$smarty = new Smarty;
$smarty->assign('test', "This is a \n Test");
$smarty->display('index.tpl');
?>

In index.tpl

{$test|nl2br}

In HTML

This is a<br />
test

I got the same error when I had Authentication disabled/chose "No Authentication'. I re-made my project and chose "Individual User Accounts" and I didn't get the error anymore.

All of the answers here currently only talk about the system properties which are different from the environment variables that are more complex to set, esp. for tests. Thankfully, below class can be used for that and the class docs has good examples

EnvironmentVariables.html

A quick example from the docs, modified to work with @SpringBootTest

@SpringBootTest
public class EnvironmentVariablesTest {
   @ClassRule
   public final EnvironmentVariables environmentVariables = new EnvironmentVariables().set("name", "value");

   @Test
   public void test() {
     assertEquals("value", System.getenv("name"));
   }
 }

An abstract class can be used instead of an interface (in C# 7.3).

// Like interface
abstract class IIO
{
    public virtual async Task<string> DoOperation(string Name)
    {
        throw new NotImplementedException(); // throwing exception
        // return await Task.Run(() => { return ""; }); // or empty do
    }
}

// Implementation
class IOImplementation : IIO
{
    public override async Task<string> DoOperation(string Name)
    {
        return await await Task.Run(() =>
        {
            if(Name == "Spiderman")
                return "ok";
            return "cancel";
        }); 
    }
}

@Chris Haas has explained very well how to use itextSharp to convert HTML to PDF, very helpful
my add is:
By using HtmlTextWriter I put html tags inside HTML table + inline CSS i got my PDF as I wanted without using XMLWorker .
Edit: adding sample code:
ASPX page:

<asp:Panel runat="server" ID="PendingOrdersPanel">
 <!-- to be shown on PDF-->
 <table style="border-spacing: 0;border-collapse: collapse;width:100%;display:none;" >

<tr style="line-height:10px;height:10px;"><td style="display:none;font-size:9px;color:#10466E;padding:0px;text-align:right;">blablabla.</td></tr>
 <tr style="line-height:10px;height:10px;"><td style="display:none;font-size:9px;color:#10466E;padding:0px;text-align:right;">blablabla.</td></tr>

For me, using Anaconda Prompt instead of cmd or PowerShell is the key.

In Anaconda Prompt, all I need to do is activate XXX

your log files shows it is stopping on error "0x8004C000"

From MS Website (http://social.technet.microsoft.com/wiki/contents/articles/15716.visual-studio-2012-and-the-error-code-2147205120.aspx):

Description
If the only block to be reported is “Reboot Pending,” the returned value is the Incomplete-Reboot Required value (0x80048bc7).

I know this is an old question, but with my quick read of the responses here, I didn't really see anyone mention that at times a synchronized method may be the wrong lock.
From Java Concurrency In Practice (pg. 72):

public class ListHelper<E> {
  public List<E> list = Collections.syncrhonizedList(new ArrayList<>());
...

public syncrhonized boolean putIfAbsent(E x) {
 boolean absent = !list.contains(x);
if(absent) {
 list.add(x);
}
return absent;
}

The above code has the appearance of being thread-safe. However, in reality it is not. In this case the lock is obtained on the instance of the class. However, it is possible for the list to be modified by another thread not using that method. The correct approach would be to use

public boolean putIfAbsent(E x) {
 synchronized(list) {
  boolean absent = !list.contains(x);
  if(absent) {
    list.add(x);
  }
  return absent;
}
}

The above code would block all threads trying to modify list from modifying the list until the synchronized block has completed.

If you don't need to support IE9 or lower, you can use flexbox freely, and don't need to use floated layouts.

It's worth noting that today, the use of floated elements for layout is getting more and more discouraged with the use of better alternatives.

• display: inline-block - Better
• Flexbox - Best (but limited browser support)

Flexbox is supported from Firefox 18, Chrome 21, Opera 12.10, and Internet Explorer 10, Safari 6.1 (including Mobile Safari) and Android's default browser 4.4.

For a detailed browser list see: https://caniuse.com/flexbox.

(Perhaps once its position is established completely, it may be the absolutely recommended way of laying out elements.)

A clearfix is a way for an element to automatically clear its child elements, so that you don't need to add additional markup. It's generally used in float layouts where elements are floated to be stacked horizontally.

The clearfix is a way to combat the zero-height container problem for floated elements

A clearfix is performed as follows:

.clearfix:after {
   content: " "; /* Older browser do not support empty content */
   visibility: hidden;
   display: block;
   height: 0;
   clear: both;
}

Or, if you don't require IE<8 support, the following is fine too:

.clearfix:after {
  content: "";
  display: table;
  clear: both;
}

Normally you would need to do something as follows:

<div>
    <div style="float: left;">Sidebar</div>
    <div style="clear: both;"></div> <!-- Clear the float -->
</div>

With clearfix, you only need the following:

<div class="clearfix">
    <div style="float: left;" class="clearfix">Sidebar</div>
    <!-- No Clearing div! -->
</div>

I think that is easier than this.

• First, create a blank target database.
• Then, in "SQL Server Management Studio" restore wizard, look for the option to overwrite target database. It is in the 'Options' tab and is called 'Overwrite the existing database (WITH REPLACE)'. Check it.
• Remember to select target files in 'Files' page.

You can change 'tabs' at left side of the wizard (General, Files, Options)

Without your seeing your data (you can use the output of dput(head(survey)) to show us) this is a shot in the dark:

survey <- data.frame(date=c("2012/07/26","2012/07/25"),tx_start=c("2012/01/01","2012/01/01"))

survey$date_diff <- as.Date(as.character(survey$date), format="%Y/%m/%d")-
                  as.Date(as.character(survey$tx_start), format="%Y/%m/%d")
survey
       date   tx_start date_diff

In Java, you just throw the exception you caught, so throw e rather than just throw. Java maintains the stack trace.

Your "application/xrds+xml" was giving me issues, I was receiving a Content-Length of 0 (no response).

After removing that, you can access the response using response.GetResponseStream().

HttpWebRequest request = WebRequest.Create("http://google.com") as HttpWebRequest;

//request.Accept = "application/xrds+xml";  
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

WebHeaderCollection header = response.Headers;

var encoding = ASCIIEncoding.ASCII;
using (var reader = new System.IO.StreamReader(response.GetResponseStream(), encoding))
{
    string responseText = reader.ReadToEnd();

RewriteBase is only applied to the target of a relative rewrite rule.

• Using RewriteBase like this...

  RewriteBase /folder/
  RewriteRule a\.html b.html
  

• is essentially the same as...

  RewriteRule a\.html /folder/b.html
  

• But when the .htaccess file is inside /folder/ then this also points to the same target:

  RewriteRule a\.html b.html
  

Although the docs imply always using a RewriteBase, Apache usually detects it correctly for paths under the DocumentRoot unless:

• You are using Alias directives

• You are using .htaccess rewrite rules to perform HTTP redirects (rather than just silent rewriting) to relative URLs

In these cases, you may find that you need to specify the RewriteBase.

However, since it's a confusing directive, it's generally better to simply specify absolute (aka 'root relative') URIs in your rewrite targets. Other developers reading your rules will grasp these more easily.

Quoting from Jon Lin's excellent in-depth answer here:

In an htaccess file, mod_rewrite works similar to a <Directory> or <Location> container. and the RewriteBase is used to provide a relative path base.

For example, say you have this folder structure:

DocumentRoot
|-- subdir1
`-- subdir2
    `-- subsubdir

So you can access:

• http://example.com/ (root)
• http://example.com/subdir1 (subdir1)
• http://example.com/subdir2 (subdir2)
• http://example.com/subdir2/subsubdir (subsubdir)

The URI that gets sent through a RewriteRule is relative to the directory containing the htaccess file. So if you have:

RewriteRule ^(.*)$ - 

• In the root htaccess, and the request is /a/b/c/d, then the captured URI ($1) is a/b/c/d.
• If the rule is in subdir2 and the request is /subdir2/e/f/g then the captured URI is e/f/g.
• If the rule is in the subsubdir, and the request is /subdir2/subsubdir/x/y/z, then the captured URI is x/y/z.

The directory that the rule is in has that part stripped off of the URI. The rewrite base has no affect on this, this is simply how per-directory works.

What the rewrite base does do, is provide a URL-path base (not a file-path base) for any relative paths in the rule's target. So say you have this rule:

RewriteRule ^foo$ bar.php [L]

The bar.php is a relative path, as opposed to:

RewriteRule ^foo$ /bar.php [L]

where the /bar.php is an absolute path. The absolute path will always be the "root" (in the directory structure above). That means that regardless of whether the rule is in the "root", "subdir1", "subsubdir", etc. the /bar.php path always maps to http://example.com/bar.php.

But the other rule, with the relative path, it's based on the directory that the rule is in. So if

RewriteRule ^foo$ bar.php [L]

is in the "root" and you go to http://example.com/foo, you get served http://example.com/bar.php. But if that rule is in the "subdir1" directory, and you go to http://example.com/subdir1/foo, you get served http://example.com/subdir1/bar.php. etc. This sometimes works and sometimes doesn't, as the documentation says, it's supposed to be required for relative paths, but most of the time it seems to work. Except when you are redirecting (using the R flag, or implicitly because you have http://host in your rule's target). That means this rule:

RewriteRule ^foo$ bar.php [L,R]

if it's in the "subdir2" directory, and you go to http://example.com/subdir2/foo, mod_rewrite will mistake the relative path as a file-path instead of a URL-path and because of the R flag, you'll end up getting redirected to something like: http://example.com/var/www/localhost/htdocs/subdir1. Which is obviously not what you want.

This is where RewriteBase comes in. The directive tells mod_rewrite what to append to the beginning of every relative path. So if I have:

RewriteBase /blah/
RewriteRule ^foo$ bar.php [L]

in "subsubdir", going to http://example.com/subdir2/subsubdir/foo will actually serve me http://example.com/blah/bar.php. The "bar.php" is added to the end of the base. In practice, this example is usually not what you want, because you can't have multiple bases in the same directory container or htaccess file.

In most cases, it's used like this:

RewriteBase /subdir1/
RewriteRule ^foo$ bar.php [L]

where those rules would be in the "subdir1" directory and

RewriteBase /subdir2/subsubdir/
RewriteRule ^foo$ bar.php [L]

would be in the "subsubdir" directory.

This partly allows you to make your rules portable, so you can drop them in any directory and only need to change the base instead of a bunch of rules. For example if you had:

RewriteEngine On
RewriteRule ^foo$ /subdir1/bar.php [L]
RewriteRule ^blah1$ /subdir1/blah.php?id=1 [L]
RewriteRule ^blah2$ /subdir1/blah2.php [L]
...

such that going to http://example.com/subdir1/foo will serve http://example.com/subdir1/bar.php etc. And say you decided to move all of those files and rules to the "subsubdir" directory. Instead of changing every instance of /subdir1/ to /subdir2/subsubdir/, you could have just had a base:

RewriteEngine On
RewriteBase /subdir1/
RewriteRule ^foo$ bar.php [L]
RewriteRule ^blah1$ blah.php?id=1 [L]
RewriteRule ^blah2$ blah2.php [L]
...

And then when you needed to move those files and the rules to another directory, just change the base:

RewriteBase /subdir2/subsubdir/

and that's it.

I'm using FirefoxOptions class to set the binary location with Firefox 52.0, GeckoDriver v0.15.0 and Selenium 3.3.1 as mentioned in this article - http://www.automationtestinghub.com/selenium-3-0-launch-firefox-with-geckodriver/

The java code that I used -

FirefoxOptions options = new FirefoxOptions();
options.setBinary("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe"); //location of FF exe

FirefoxDriver driver = new FirefoxDriver(options);
driver.get("http://www.google.com");

In addition to the value you wish to print, the {0} {1}, etc., you can specify a format. For example, {0,4} will be a value that is padded to four spaces.

There are a number of built-in format specifiers, and in addition, you can make your own. For a decent tutorial/list see String Formatting in C#. Also, there is a FAQ here.

In order to do this you need to attach the handler to a specific anchor on the page. For operations like this it's much easier to use a standard framework like jQuery. For example if I had the following HTML

HTML:

<a id="theLink">Click Me</a>

I could use the following jQuery to hookup an event to that specific link.

// Use ready to ensure document is loaded before running javascript
$(document).ready(function() {

  // The '#theLink' portion is a selector which matches a DOM element
  // with the id 'theLink' and .click registers a call back for the 
  // element being clicked on 
  $('#theLink').click(function (event) {

    // This stops the link from actually being followed which is the 
    // default action 
    event.preventDefault();

    var answer confirm("Please click OK to continue");
    if (!answer) {
      window.location="http://www.continue.com"
    }
  });

});

Try to run xcrun simctl delete unavailable in your terminal.

Answering this has been good, as the comments have led to an improvement in my own understanding of Python variables.

As noted in the comments, when you loop over a list with something like for member in my_list the member variable is bound to each successive list element. However, re-assigning that variable within the loop doesn't directly affect the list itself. For example, this code won't change the list:

my_list = [1,2,3]
for member in my_list:
    member = 42
print my_list

Output:

[1, 2, 3]

If you want to change a list containing immutable types, you need to do something like:

my_list = [1,2,3]
for ndx, member in enumerate(my_list):
    my_list[ndx] += 42
print my_list

Output:

[43, 44, 45]

If your list contains mutable objects, you can modify the current member object directly:

class C:
    def __init__(self, n):
        self.num = n
    def __repr__(self):
        return str(self.num)

my_list = [C(i) for i in xrange(3)]
for member in my_list:
    member.num += 42
print my_list

[42, 43, 44]

Note that you are still not changing the list, simply modifying the objects in the list.

The Host Header tells the webserver which virtual host to use (if set up). You can even have the same virtual host using several aliases (= domains and wildcard-domains). In this case, you still have the possibility to read that header manually in your web app if you want to provide different behavior based on different domains addressed. This is possible because in your webserver you can (and if I'm not mistaken you must) set up one vhost to be the default host. This default vhost is used whenever the host header does not match any of the configured virtual hosts.

That means: You get it right, although saying "multiple hosts" may be somewhat misleading: The host (the addressed machine) is the same, what really gets resolved to the IP address are different domain names (including subdomains) that are also referred to as hostnames (but not hosts!).

Although not part of the question, a fun fact: This specification led to problems with SSL in early days because the web server has to deliver the certificate that corresponds to the domain the client has addressed. However, in order to know what certificate to use, the webserver should have known the addressed hostname in advance. But because the client sends that information only over the encrypted channel (which means: after the certificate has already been sent), the server had to assume you browsed the default host. That meant one ssl-secured domain per IP address / port-combination.

This has been overcome with Server Name Indication; however, that again breaks some privacy, as the server name is now transferred in plain text again, so every man-in-the-middle would see which hostname you are trying to connect to.

Although the webserver would know the hostname from Server Name Indication, the Host header is not obsolete, because the Server Name Indication information is only used within the TLS handshake. With an unsecured connection, there is no Server Name Indication at all, so the Host header is still valid (and necessary).

Another fun fact: Most webservers (if not all) reject your HTTP request if it does not contain exactly one Host header, even if it could be omitted because there is only the default vhost configured. That means the minimum required information in an http-(get-)request is the first line containing METHOD RESOURCE and PROTOCOL VERSION and at least the Host header, like this:

GET /someresource.html HTTP/1.1
Host: www.example.com

In the MDN Documentation on the "Host" header they actually phrase it like this:

A Host header field must be sent in all HTTP/1.1 request messages. A 400 (Bad Request) status code will be sent to any HTTP/1.1 request message that lacks a Host header field or contains more than one.

As mentioned by Darrel Miller, the complete specs can be found in RFC7230.

Angular deprecated $cookieStore in version 1.4.x, so use $cookies instead if you are using latest version of angular. Syntax remain same for $cookieStore & $cookies:

$cookies.put("key", "value"); 
var value = $cookies.get("key");

See the Docs for an API overview. Mind also that the cookie service has been enhanced with some new important features like setting expiration (see this answer) and domain (see CookiesProvider Docs).

Note that, in version 1.3.x or below, $cookies has a different syntax than above:

$cookies.key = "value";
var value = $cookies.value; 

Also if you are using bower, make sure to type your package name correctly:

bower install [email protected] 

where X.Y.Z is the AngularJS version you are running. There's another package in bower "angular-cookie"(without the 's') which is not the official angular package.

This should work:

endstring = ''.join(list)

Just add them:

['it'] + ['was'] + ['annoying']

You should read the Python tutorial to learn basic info like this.

To convert an integer to a float in Python you can use the following:

float_version = float(int_version)

The reason you are getting 0 is that Python 2 returns an integer if the mathematical operation (here a division) is between two integers. So while the division of 144 by 314 is 0.45~~~, Python converts this to integer and returns just the 0 by eliminating all numbers after the decimal point.

Alternatively you can convert one of the numbers in any operation to a float since an operation between a float and an integer would return a float. In your case you could write float(144)/314 or 144/float(314). Another, less generic code, is to say 144.0/314. Here 144.0 is a float so it’s the same thing.

Following can also be done. If you want to append prepend icon. This will be helpful.

<?php $form = ActiveForm::begin();    
   echo $form->field($model, 'field')->begin();
     echo Html::activeLabel($model, 'field', ["class"=>"control-label col-md-4"]); ?>
       <div class="col-md-5">
          <?php echo Html::activeDropDownList($model, 'field', $array_list, ['class'=>'form-control']); ?>
          <p><i><small>Please select field</small></i>.</p>
          <?php echo Html::error($model, 'field', ['class'=>'help-block']); ?>
       </div>
   <?php echo $form->field($model, 'field')->end(); 
ActiveForm::end();?>

To convert an integer to a string:

integer :: i    
character* :: s    
if (i.LE.9) then
     s=char(48+i)    
else if (i.GE.10) then
     s=char(48+(i/10))// char(48-10*(i/10)+i)    
endif

In windows you should use %WORKSPACE%.

Add text-align: center; to the parent tag of <canvas>. That's it.

Example:

If your entity class isn't in the same package as your main class, you can use @EntityScan annotation in the main class, specifying the Entity you want to save or package too. Like your model package.

About:

spring.jpa.hibernate.ddl-auto = create

You can use the option update. It won't erase any data, and will create tables in the same way.

1. Modern C++20 solution

auto cmp = [](int a, int b) { return ... };
std::set<int, decltype(cmp)> s;

We use lambda function as comparator. As usual, comparator should return boolean value, indicating whether the element passed as first argument is considered to go before the second in the specific strict weak ordering it defines.

Online demo

2. Modern C++11 solution

auto cmp = [](int a, int b) { return ... };
std::set<int, decltype(cmp)> s(cmp);

Before C++20 we need to pass lambda as argument to set constructor

Online demo

3. Similar to first solution, but with function instead of lambda

Make comparator as usual boolean function

bool cmp(int a, int b) {
    return ...;
}

Then use it, either this way:

std::set<int, decltype(cmp)*> s(cmp);

Online demo

or this way:

std::set<int, decltype(&cmp)> s(&cmp);

Online demo

4. Old solution using struct with () operator

struct cmp {
    bool operator() (int a, int b) const {
        return ...
    }
};

// ...
// later
std::set<int, cmp> s;

Online demo

5. Alternative solution: create struct from boolean function

Take boolean function

bool cmp(int a, int b) {
    return ...;
}

And make struct from it using std::integral_constant

#include <type_traits>
using Cmp = std::integral_constant<decltype(&cmp), &cmp>;

Finally, use the struct as comparator

std::set<X, Cmp> set;

This is how I worked with local swagger JSON

1. Have tomcat running in local machine
2. Download Swagger UI application and unzip it into tomcat's /webapps/swagger folder
3. Drop local swagger json file inside /webapps/swagger folder of tomcat
4. Start up tomcat (/bin/sh startup.sh)
5. Open a browser and navigate to http://localhost:8080/swagger/
6. type your swagger json file in the Swagger Explore test box and this should render the APIs.

Hope this works for you

If you are using a more modern version of Rails and it uses Puma as the web server, you can run the following command to find the stuck Puma process:

ps aux | grep puma

It will result in output similar to this:

85923 100.0  0.8  2682420 131324 s004  R+    2:54pm   3:27.92 puma 3.12.0 (tcp://0.0.0.0:3010) [my-app]
92463   0.0  0.0  2458404   1976 s008  S+    3:09pm   0:00.00 grep puma

You want the process that is not referring to grep. In this case, the process ID is 85923.

I can then run the following command to kill that process:

kill -9 85923

One possible explanation is a database trigger that fires for each DROP TABLE statement. To find the trigger, query the _TRIGGERS dictionary views:

select * from all_triggers
where trigger_type in ('AFTER EVENT', 'BEFORE EVENT')

disable any suspicious trigger with

   alter trigger <trigger_name> disable;

and try re-running your DROP TABLE statement

f = open('test.txt','r')
for line in f.xreadlines():
    print line
f.close()

Guys am facing similar issue here is my full code

Quick Update, effective from February 15th, 2015, we cannot submit apps to the store that were developed using an SDK prior to iOS 8. So, keeping that in mind , its better to not to worry about this issue as many people have suggested that apps made in Swift can be deployed to OS X 10.9 and iOS 7.0 as well.

Use -1 as the start position:

INSTR('JD-EQ-0001', '-', -1)

In your example, the IF statement will run when it is state = true meaning the else part will run when state = false.

if(turnedOn == true) is the same as if(turnedOn)

if(turnedOn == false) is the same as if(!turnedOn)

If you have:

boolean turnedOn = false;

Or

boolean turnedOn;

Then

if(turnedOn)
{

}
else
{
    // This would run!
}

in my case, I declared one static variable in .h file, like

//myClass.h
class myClass
{
static int m_nMyVar;
static void myFunc();
}

and in myClass.cpp, I tried to use this m_nMyVar. It got LINK error like:

error LNK2001: unresolved external symbol "public: static class... The link error related cpp file looks like:

//myClass.cpp
void myClass::myFunc()
{
myClass::m_nMyVar = 123; //I tried to use this m_nMyVar here and got link error
}

So I add below code on the top of myClass.cpp

//myClass.cpp
int myClass::m_nMyVar; //it seems redefine m_nMyVar, but it works well
void myClass::myFunc()
{
myClass::m_nMyVar = 123; //I tried to use this m_nMyVar here and got link error
}

then LNK2001 is gone.

An UpdatePanel completely replaces the contents of the update panel on an update. This means that those events you subscribed to are no longer subscribed because there are new elements in that update panel.

What I've done to work around this is re-subscribe to the events I need after every update. I use $(document).ready() for the initial load, then use Microsoft's PageRequestManager (available if you have an update panel on your page) to re-subscribe every update.

$(document).ready(function() {
    // bind your jQuery events here initially
});

var prm = Sys.WebForms.PageRequestManager.getInstance();

prm.add_endRequest(function() {
    // re-bind your jQuery events here
});

The PageRequestManager is a javascript object which is automatically available if an update panel is on the page. You shouldn't need to do anything other than the code above in order to use it as long as the UpdatePanel is on the page.

If you need more detailed control, this event passes arguments similar to how .NET events are passed arguments (sender, eventArgs) so you can see what raised the event and only re-bind if needed.

Here is the latest version of the documentation from Microsoft: msdn.microsoft.com/.../bb383810.aspx

A better option you may have, depending on your needs, is to use jQuery's .on(). These method are more efficient than re-subscribing to DOM elements on every update. Read all of the documentation before you use this approach however, since it may or may not meet your needs. There are a lot of jQuery plugins that would be unreasonable to refactor to use .delegate() or .on(), so in those cases, you're better off re-subscribing.

Using junit4 and Hamcrest you get a concise method of comparing arrays. It also gives details of where the error is in the failure trace.

import static org.junit.Assert.*
import static org.hamcrest.CoreMatchers.*;

//...

assertThat(result, is(new int[] {56, 100, 2000}));

Failure Trace output:

java.lang.AssertionError: 
   Expected: is [<56>, <100>, <2000>]
   but: was [<55>, <100>, <2000>]

If you are using Java 5/6, you can use Apache Commons IO for read file to string. The class org.apache.commons.io.FileUtils contais several method for read files.

e.g. using the method FileUtils#readFileToString:

File file = new File("abc.txt");
String content = FileUtils.readFileToString(file);

how about gets ?

myFile=File.open("paths_to_file","r")
while(line=myFile.gets)
 //do stuff with line
end

I had the same issue and i had it formatted into JSON as a String instead. Might be a bit of a hack but it's easy to implement.

private BigDecimal myValue = new BigDecimal("25.50");
...
public String getMyValue() {
    return myValue.setScale(2, BigDecimal.ROUND_HALF_UP).toString();
}

Use the length() method in the File class. From the javadocs:

Returns the length of the file denoted by this abstract pathname. The return value is unspecified if this pathname denotes a directory.

UPDATED Nowadays we should use the Files.size() method:

Paths path = Paths.get("/path/to/file");
long size = Files.size(path);

For the second part of the question, straight from File's javadocs:

• getUsableSpace() Returns the number of bytes available to this virtual machine on the partition named by this abstract pathname

• getTotalSpace() Returns the size of the partition named by this abstract pathname

• getFreeSpace() Returns the number of unallocated bytes in the partition named by this abstract path name

This was the first result on google when I pasted my error message, and it's because my arguments were out of order.

The container name has to be after all of the arguments.

Bad:

docker run <container_name> -v $(pwd):/src -it

Good:

docker run -v $(pwd):/src -it <container_name>

The simplest way:

if (Request.IsAuthenticated) ...

Similar to the top answer, I used the unicode character in the value= section of the HTML and called FontAwesome as the font family on that input element. The only thing I'll add that the top answer doesn't cover is that because my value element also had text inside it after the icon, changing the font family to FontAwesome made the regular text look bad. The solution was simply to change the CSS to include fallback fonts:

<input type="text" id="datepicker" placeholder="Change Date" value="? Sat Oct 19" readonly="readonly" class="hasDatepicker">

font-family: FontAwesome, Roboto, sans-serif;

This way, FontAwesome will grab the icon, but all non-icon text will have the desired font applied.

This article helped explain a lot of things. It's in FAQ style.

Async/Await FAQ

This part explains why Thread.Sleep runs on the same original thread - leading to my initial confusion.

Does the “async” keyword cause the invocation of a method to queue to the ThreadPool? To create a new thread? To launch a rocket ship to Mars?

No. No. And no. See the previous questions. The “async” keyword indicates to the compiler that “await” may be used inside of the method, such that the method may suspend at an await point and have its execution resumed asynchronously when the awaited instance completes. This is why the compiler issues a warning if there are no “awaits” inside of a method marked as “async”.

You forgot the dot of class selector of result class.

Live Demo

$(".result").hover(
  function () {
    $(this).addClass("result_hover");
  },
  function () {
    $(this).removeClass("result_hover");
  }
);

You can use toggleClass on hover event

Live Demo

 $(".result").hover(function () {
    $(this).toggleClass("result_hover");
 });

I found a way to automate running the clean before you debug your code. (Warning, this runs everytime you hit the button, even for hot restart)

1. First, find the Run > Edit Configurations Menu

2. Click the External tool '+' icon under Before launch: External tool, Activate tool window.

3. Run External Tool
4. Configure it like so. Put the working directory as a directory in your project.

The answer is misleading because it attempts to fix a problem that is not a problem. You actually CAN have a WHERE CLAUSE in each segment of a UNION. You cannot have an ORDER BY except in the last segment. Therefore, this should work...

select top 2 t1.ID, t1.ReceivedDate
from Table t1
where t1.Type = 'TYPE_1'
-----remove this-- order by ReceivedDate desc
union
select top 2 t2.ID,  t2.ReceivedDate --- add second column
  from Table t2
 where t2.Type = 'TYPE_2'
order by ReceivedDate desc

There are two parts to that answer (I wrote it). One part is easy to quantify, the other is more empirical.

Hardware Constraints:

This is the easy to quantify part. Appendix F of the current CUDA programming guide lists a number of hard limits which limit how many threads per block a kernel launch can have. If you exceed any of these, your kernel will never run. They can be roughly summarized as:

1. Each block cannot have more than 512/1024 threads in total (Compute Capability 1.x or 2.x and later respectively)
2. The maximum dimensions of each block are limited to [512,512,64]/[1024,1024,64] (Compute 1.x/2.x or later)
3. Each block cannot consume more than 8k/16k/32k/64k/32k/64k/32k/64k/32k/64k registers total (Compute 1.0,1.1/1.2,1.3/2.x-/3.0/3.2/3.5-5.2/5.3/6-6.1/6.2/7.0)
4. Each block cannot consume more than 16kb/48kb/96kb of shared memory (Compute 1.x/2.x-6.2/7.0)

If you stay within those limits, any kernel you can successfully compile will launch without error.

Performance Tuning:

This is the empirical part. The number of threads per block you choose within the hardware constraints outlined above can and does effect the performance of code running on the hardware. How each code behaves will be different and the only real way to quantify it is by careful benchmarking and profiling. But again, very roughly summarized:

1. The number of threads per block should be a round multiple of the warp size, which is 32 on all current hardware.
2. Each streaming multiprocessor unit on the GPU must have enough active warps to sufficiently hide all of the different memory and instruction pipeline latency of the architecture and achieve maximum throughput. The orthodox approach here is to try achieving optimal hardware occupancy (what Roger Dahl's answer is referring to).

The second point is a huge topic which I doubt anyone is going to try and cover it in a single StackOverflow answer. There are people writing PhD theses around the quantitative analysis of aspects of the problem (see this presentation by Vasily Volkov from UC Berkley and this paper by Henry Wong from the University of Toronto for examples of how complex the question really is).

At the entry level, you should mostly be aware that the block size you choose (within the range of legal block sizes defined by the constraints above) can and does have a impact on how fast your code will run, but it depends on the hardware you have and the code you are running. By benchmarking, you will probably find that most non-trivial code has a "sweet spot" in the 128-512 threads per block range, but it will require some analysis on your part to find where that is. The good news is that because you are working in multiples of the warp size, the search space is very finite and the best configuration for a given piece of code relatively easy to find.

The ErrorDocument directive, when supplied a local URL path, expects the path to be fully qualified from the DocumentRoot. In your case, this means that the actual path to the ErrorDocument is

ErrorDocument 404 /hellothere/error/404page.html

I use exactly the same sass mixin placeholder as NoDirection wrote. I find it in sass mixins collection here and I'm very satisfied with it. There's a text that explains a mixins option more.

In addition to the answers posted here, make sure you read this article:

http://24ways.org/2009/rock-solid-html-emails

Use regular expression to achieve this task. Please refer the below code.

public static void main(String[] args) {
    try {

        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        System.out.print("Enter your content: ");
        String data = reader.readLine();            
        boolean b1 = Pattern.matches("^\\d+$", data);
        boolean b2 = Pattern.matches("[0-9a-zA-Z([+-]?\\d*\\.+\\d*)]*", data); 
        boolean b3 = Pattern.matches("^([+-]?\\d*\\.+\\d*)$", data);
        if(b1) {
            System.out.println("It is integer.");
        } else if(b2) {
            System.out.println("It is String. ");
        } else if(b3) {
            System.out.println("It is Float. ");
        }           
    } catch (IOException ex) {
        Logger.getLogger(TypeOF.class.getName()).log(Level.SEVERE, null, ex);
    }
}

So here's what I did eventually. I hope this helps someone else.

class NoDuplicatesList<E> extends LinkedList<E> {
    @Override
    public boolean add(E e) {
        if (this.contains(e)) {
            return false;
        }
        else {
            return super.add(e);
        }
    }

    @Override
    public boolean addAll(Collection<? extends E> collection) {
        Collection<E> copy = new LinkedList<E>(collection);
        copy.removeAll(this);
        return super.addAll(copy);
    }

    @Override
    public boolean addAll(int index, Collection<? extends E> collection) {
        Collection<E> copy = new LinkedList<E>(collection);
        copy.removeAll(this);
        return super.addAll(index, copy);
    }

    @Override
    public void add(int index, E element) {
        if (this.contains(element)) {
            return;
        }
        else {
            super.add(index, element);
        }
    }
}   

@JorgeGRC Thanks for your answer. One thing though, the "maybe" part is very important. If you do have parameter(s), you must include it/them on your template as well and be sure to specify your locals e.g. updateFn({msg: "Directive Args"}.

Use this code:

driver.manage().window().maximize() 

works well,

Please make sure that you give enough time for the window to load before you declare this statement.

If you are finding any element to input some data then provide reasonable delay between this and the input statement.

This will get you the timezone as a PHP variable. I wrote a function using jQuery and PHP. This is tested, and does work!

On the PHP page where you are want to have the timezone as a variable, have this snippet of code somewhere near the top of the page:

<?php    
    session_start();
    $timezone = $_SESSION['time'];
?>

This will read the session variable "time", which we are now about to create.

On the same page, in the <head> section, first of all you need to include jQuery:

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>

Also in the <head> section, paste this jQuery:

<script type="text/javascript">
    $(document).ready(function() {
        if("<?php echo $timezone; ?>".length==0){
            var visitortime = new Date();
            var visitortimezone = "GMT " + -visitortime.getTimezoneOffset()/60;
            $.ajax({
                type: "GET",
                url: "http://example.com/timezone.php",
                data: 'time='+ visitortimezone,
                success: function(){
                    location.reload();
                }
            });
        }
    });
</script>

You may or may not have noticed, but you need to change the url to your actual domain.

One last thing. You are probably wondering what the heck timezone.php is. Well, it is simply this: (create a new file called timezone.php and point to it with the above url)

<?php
    session_start();
    $_SESSION['time'] = $_GET['time'];
?>

If this works correctly, it will first load the page, execute the JavaScript, and reload the page. You will then be able to read the $timezone variable and use it to your pleasure! It returns the current UTC/GMT time zone offset (GMT -7) or whatever timezone you are in.

I created the alias dog for showing the log graph:

git config --global alias.dog "log --all --decorate --oneline --graph"

And use it as follows:

I remember reading that there are 2 kinds of Switch statements in Java bytecode. (I think it was in 'Java Performance Tuning' One is a very fast implementation which uses the switch statement's integer values to know the offset of the code to be executed. This would require all integers to be consecutive and in a well-defined range. I'm guessing that using all the values of an Enum would fall in that category too.

I agree with many other posters though... it may be premature to worry about this, unless this is very very hot code.

If it has to be accessible with a global scope

global.fetch = require("node-fetch");

This is a quick dirty fix, please try to eliminate this usage in production code.

I have created a ultimate small js npm library for the base64 encode/decode conversion in Node.js.

Installation

npm install nodejs-base64-converter --save

Usage

var nodeBase64 = require('nodejs-base64-converter');

console.log(nodeBase64.encode("test text")); //dGVzdCB0ZXh0
console.log(nodeBase64.decode("dGVzdCB0ZXh0")); //test text

If you're doing an unusual import (e.g., it's an options file), try:

import inspect
print (inspect.getfile(inspect.currentframe()))

Note that this will return the absolute path to the file.

Unity 5.6.1 / 2017.1 fixes the Android SDK Tools 25.3.1+ compatibility issue. This is noted in Unity bug tracker under issue 888859 and their 5.6.1 release notes.

You can simply use multiprocessing.Pool:

from multiprocessing import Pool

def process_image(name):
    sci=fits.open('{}.fits'.format(name))
    <process>

if __name__ == '__main__':
    pool = Pool()                         # Create a multiprocessing Pool
    pool.map(process_image, data_inputs)  # process data_inputs iterable with pool

first you should be sure that selenium is installed in your system.

then install pycharm https://itsfoss.com/install-pycharm-ubuntu/

now if an of packages are not installed it will show red underlines. click on it and install from pycharm.

like for this case click on selenium option in import statement, there you would getting some options. click on install selenium. it will install and automatically run the code successfully if all your drivers are placed in proper directories.

Here's a stdlib solution that supports a variable utc offset in the input time string:

>>> from email.utils import parsedate_tz, mktime_tz
>>> from datetime import datetime, timedelta
>>> timestamp = mktime_tz(parsedate_tz('Tue May 08 15:14:45 +0800 2012'))
>>> utc_time = datetime(1970, 1, 1) + timedelta(seconds=timestamp)
>>> utc_time
datetime.datetime(2012, 5, 8, 7, 14, 45)

Ruby 2.5+

As of Ruby 2.5 you can use delete_suffix or delete_suffix! to achieve this in a fast and readable manner.

The docs on the methods are here.

If you know what the suffix is, this is idiomatic (and I'd argue, even more readable than other answers here):

'abc123'.delete_suffix('123')     # => "abc"
'abc123'.delete_suffix!('123')    # => "abc"

It's even significantly faster (almost 40% with the bang method) than the top answer. Here's the result of the same benchmark:

                     user     system      total        real
chomp            0.949823   0.001025   0.950848 (  0.951941)
range            1.874237   0.001472   1.875709 (  1.876820)
delete_suffix    0.721699   0.000945   0.722644 (  0.723410)
delete_suffix!   0.650042   0.000714   0.650756 (  0.651332)

I hope this is useful - note the method doesn't currently accept a regex so if you don't know the suffix it's not viable for the time being. However, as the accepted answer (update: at the time of writing) dictates the same, I thought this might be useful to some people.

You're synchronizing twice, which is pointless and possibly slows down the code: changes while iterating over the list need a synchronnization over the entire operation, which you are doing with synchronized (in_queue_list) Using Collections.synchronizedList() is superfluous in that case (it creates a wrapper that synchronizes individual operations).

However, since you are emptying the list completely, the iterated removal of the first element is the worst possible way to do it, sice for each element all following elements have to be copied, making this an O(n^2) operation - horribly slow for larger lists.

Instead, simply call clear() - no iteration needed.

Edit: If you need the single-method synchronization of Collections.synchronizedList() later on, then this is the correct way:

List<Record> in_queue_list = Collections.synchronizedList(in_queue);
in_queue_list.clear(); // synchronized implicitly, 

But in many cases, the single-method synchronization is insufficient (e.g. for all iteration, or when you get a value, do computations based on it, and replace it with the result). In that case, you have to use manual synchronization anyway, so Collections.synchronizedList() is just useless additional overhead.

You may create a fake property or use an existing one and inherit it in the pseudo-element's stylesheet.

var switched = false;_x000D_

// Enable color switching_x000D_

It seems it doesn't work for "content" property :(

In your home directory, you should edit .bash_profile if you have Git for Windows 2.21.0 or later (as of this writing).

You could direct .bash_profile to just source .bashrc, but if something happens to your .bash_profile, then it will be unclear why your .bashrc is again not working.

I put all my aliases and other environment stuff in .bash_profile, and I also added this line:

echo "Sourcing ~/.bash_profile - this version of Git Bash doesn't use .bashrc"

And THEN, in .bashrc I have

echo "This version of Git Bash doesn't use .bashrc. Use .bash_profile instead"

(Building on @harsel's response. I woulda commented, but I have no points yet.)

You have to define your exception elsewhere as a new class

public class YourCustomException extends Exception{

//Required inherited methods here
}

Then you can throw and catch YourCustomException as much as you'd like.

Inside ContentPlaceholder, put the placeholder control.For Example like this,

<asp:Content ID="header" ContentPlaceHolderID="head" runat="server">
       <asp:PlaceHolder ID="metatags" runat="server">
        </asp:PlaceHolder>
</asp:Content>

Code Behind:

HtmlMeta hm1 = new HtmlMeta();
hm1.Name = "Description";
hm1.Content = "Content here";
metatags.Controls.Add(hm1);

For a bit more flexibility than with micronyks answer, you can do it like that:

1. In your template, add #myIdentifier to the element you want to obtain the width from. Example:

<p #myIdentifier>
  my-component works!
</p>

2. In your controller, you can use this with @ViewChild('myIdentifier') to get the width:

import {AfterViewInit, Component, ElementRef, OnInit, ViewChild} from '@angular/core';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.scss']
})
export class MyComponentComponent implements AfterViewInit {

  constructor() { }

  ngAfterViewInit() {
    console.log(this.myIdentifier.nativeElement.offsetWidth);
  }

  @ViewChild('myIdentifier')
  myIdentifier: ElementRef;

}

Security

About the security risk with ElementRef, like this, there is none. There would be a risk, if you would modify the DOM using an ElementRef. But here you are only getting DOM Elements so there is no risk. A risky example of using ElementRef would be: this.myIdentifier.nativeElement.onclick = someFunctionDefinedBySomeUser;. Like this Angular doesn't get a chance to use its sanitisation mechanisms since someFunctionDefinedBySomeUser is inserted directly into the DOM, skipping the Angular sanitisation.

xyz.setColumns() method is control the width of TextField.

Sometimes a binder throwns an exception with no error message. You can retrieve the exception with the following snippet to find out whats wrong:

(Often if the binder is trying to convert strings to complex types etc)

 if (!ModelState.IsValid)
            {
var errors = ModelState.SelectMany(x => x.Value.Errors.Select(z => z.Exception));

// Breakpoint, Log or examine the list with Exceptions.

  }

The API Guide has it all wrong (really Google?). With Maps API v2 you do not need to enable a layer to show yourself, there is a simple call to the GoogleMaps instance you created with your map.

Google Documentation

The actual documentation that Google provides gives you your answer. You just need to

If you are using Kotlin

// map is a GoogleMap object
map.isMyLocationEnabled = true

If you are using Java

// map is a GoogleMap object
map.setMyLocationEnabled(true);

and watch the magic happen.

Just make sure that you have location permission and requested it at runtime on API Level 23 (M) or above

Few antivirus programs detect adb.exe as a virus. You should take a look in the place where antivirus is putting your detected threats and restore it from there. For Avast Antivirus is inside of virus chest

Hope it will be useful for someone !

according to this snippet i use this code and it's working fine:

using System;
using System.IO;
using System.IO.Compression;
using System.Text;

    internal static class StringCompressor
    {

        public static string CompressString(string text)
        {
            byte[] buffer = Encoding.UTF8.GetBytes(text);
            var memoryStream = new MemoryStream();
            using (var gZipStream = new GZipStream(memoryStream, CompressionMode.Compress, true))
            {
                gZipStream.Write(buffer, 0, buffer.Length);

VLookup

You can do it with a simple VLOOKUP formula. I've put the data in the same sheet, but you can also reference a different worksheet. For the price column just change the last value from 2 to 3, as you are referencing the third column of the matrix "A2:C4".

External Reference

To reference a cell of the same Workbook use the following pattern:

<Sheetname>!<Cell>

Example:

Table1!A1

To reference a cell of a different Workbook use this pattern:

[<Workbook_name>]<Sheetname>!<Cell>

Example:

[MyWorkbook]Table1!A1

_splitpath should do what you need. You could of course do it manually but _splitpath handles all special cases as well.

EDIT:

As BillHoag mentioned it is recommended to use the more safe version of _splitpath called _splitpath_s when available.

Or if you want something portable you could just do something like this

std::vector<std::string> splitpath(
  const std::string& str
  , const std::set<char> delimiters)
{
  std::vector<std::string> result;

  char const* pch = str.c_str();
  char const* start = pch;
  for(; *pch; ++pch)
  {
    if (delimiters.find(*pch) != delimiters.end())
    {
      if (start != pch)
      {
        std::string str(start, pch);
        result.push_back(str);
      }
      else
      {
        result.push_back("");
      }
      start = pch + 1;
    }
  }
  result.push_back(start);

  return result;
}

...
std::set<char> delims{'\\'};

std::vector<std::string> path = splitpath("C:\\MyDirectory\\MyFile.bat", delims);
cout << path.back() << endl;

Most of the answers here are wrong. The right answer is it depends. For example, here are two C functions which walks through a tree. First the recursive one:

static
void mm_scan_black(mm_rc *m, ptr p) {
    SET_COL(p, COL_BLACK);
    P_FOR_EACH_CHILD(p, {
        INC_RC(p_child);
        if (GET_COL(p_child) != COL_BLACK) {
            mm_scan_black(m, p_child);
        }
    });
}

And here is the same function implemented using iteration:

static
void mm_scan_black(mm_rc *m, ptr p) {
    stack *st = m->black_stack;
    SET_COL(p, COL_BLACK);
    st_push(st, p);
    while (st->used != 0) {
        p = st_pop(st);
        P_FOR_EACH_CHILD(p, {
            INC_RC(p_child);
            if (GET_COL(p_child) != COL_BLACK) {
                SET_COL(p_child, COL_BLACK);
                st_push(st, p_child);
            }
        });
    }
}

It's not important to understand the details of the code. Just that p are nodes and that P_FOR_EACH_CHILD does the walking. In the iterative version we need an explicit stack st onto which nodes are pushed and then popped and manipulated.

The recursive function runs much faster than the iterative one. The reason is because in the latter, for each item, a CALL to the function st_push is needed and then another to st_pop.

In the former, you only have the recursive CALL for each node.

Plus, accessing variables on the callstack is incredibly fast. It means you are reading from memory which is likely to always be in the innermost cache. An explicit stack, on the other hand, has to be backed by malloc:ed memory from the heap which is much slower to access.

With careful optimization, such as inlining st_push and st_pop, I can reach roughly parity with the recursive approach. But at least on my computer, the cost of accessing heap memory is bigger than the cost of the recursive call.

But this discussion is mostly moot because recursive tree walking is incorrect. If you have a large enough tree, you will run out of callstack space which is why an iterative algorithm must be used.

I had this error when I used a launch configuration that had an invalid classpath. In my case, I had a project that initially used Maven and thus a launch configuration had a Maven classpath element in it. I had later changed the project to use Gradle and removed the Maven classpath from the project's classpath, but the launch configuration still used it. I got this error trying to run it. Cleaning and rebuilding the project did not resolve this error. Instead, edit the launch configuration, remove the project classpath element, then add the project back to the User Entries in the classpath.

I was running Eclipse Neon.2 and the Android SDK Build-tools + platform-tools version 26 on Mac OS 10.12.4 and none of the above answers (including the accepted answer) worked for me.

What did work was to

1. Quit Eclipse

2. Remove the folder <android-sdk>/build-tools/26.0.0 and to install the (older) version 25.0.3 of the build tools through the Android SDK manager.

3. Start Eclipse again

Please check this function - it converts timedelta object into string 'HH:MM:SS'

def format_timedelta(td):
    hours, remainder = divmod(td.total_seconds(), 3600)
    minutes, seconds = divmod(remainder, 60)
    hours, minutes, seconds = int(hours), int(minutes), int(seconds)
    if hours < 10:
        hours = '0%s' % int(hours)
    if minutes < 10:
        minutes = '0%s' % minutes
    if seconds < 10:
        seconds = '0%s' % seconds
    return '%s:%s:%s' % (hours, minutes, seconds)

You just need to remove the hash from the beginning:

$('a.pagerlink').click(function() { 
    var id = $(this).attr('id').substring(1);
    $container.cycle(id); 
    return false; 
}); 

try this:

$prices = array_column($inventory, 'price');
array_multisort($prices, SORT_DESC, $inventory);
print_r($inventory);

For safety, I always parenthesise my comparisons and space them out. That way, I don't have to rely on operator precedence:

if( 
    ((i==0) && (b==2)) 
    || 
    ((c==3) && !(f==5)) 
  )

In case anyone was a tired and silly as I was the other night whereupon I came across many threads espousing the different methods to get a javascript redirect, all of which were failing...

You can't use window.location.replace or document.location.href or any of your favourite vanilla javascript methods to redirect a page to itself.

So if you're dynamically adding in the redirect path from the back end, or pulling it from a data tag, make sure you do check at some stage for redirects to the current page. It could be as simple as:

if(window.location.href == linkout)
{
    location.reload();
}
else
{
    window.location.href = linkout;
}

Here is the alternative command:

gnuplot -p -e 'plot for [file in system("find . -name \\*.txt -depth 1")] file using 1:2 title file with lines'

Here is where you went wrong:

this.result = http.get('friends.json')
                  .map(response => response.json())
                  .subscribe(result => this.result =result.json());

it should be:

http.get('friends.json')
                  .map(response => response.json())
                  .subscribe(result => this.result =result);

or

http.get('friends.json')
                  .subscribe(result => this.result =result.json());

You have made two mistakes:

1- You assigned the observable itself to this.result. When you actually wanted to assign the list of friends to this.result. The correct way to do it is:

• you subscribe to the observable. .subscribe is the function that actually executes the observable. It takes three callback parameters as follow:

  .subscribe(success, failure, complete);

for example:

.subscribe(
    function(response) { console.log("Success Response" + response)},
    function(error) { console.log("Error happened" + error)},
    function() { console.log("the subscription is completed")}
);

Usually, you take the results from the success callback and assign it to your variable. the error callback is self explanatory. the complete callback is used to determine that you have received the last results without any errors. On your plunker, the complete callback will always be called after either the success or the error callback.

2- The second mistake, you called .json() on .map(res => res.json()), then you called it again on the success callback of the observable. .map() is a transformer that will transform the result to whatever you return (in your case .json()) before it's passed to the success callback you should called it once on either one of them.

If you have a custom.css file, in there, just do something like:

font-family: "Oswald", Helvetica, Arial, sans-serif!important;

I realize this question's time has come and gone, but since I was working on a solver myself, and stumbled onto this while googling about, I thought I should post a reference to mine as it seems a bit different from some of the others.

I chose to go with a flat array for the game board, and to do recursive hunts from each letter on the board, traversing from valid neighbor to valid neighbor, extending the hunt if the current list of letters if a valid prefix in an index. While traversing the notion of the current word is list of indexes into board, not letters that make up a word. When checking the index, the indexes are translated to letters and the check done.

The index is a brute force dictionary that's a bit like a trie, but allows for Pythonic queries of the index. If the words 'cat' and 'cater' are in the list, you'll get this in the dictionary:

   d = { 'c': ['cat','cater'],
     'ca': ['cat','cater'],
     'cat': ['cat','cater'],
     'cate': ['cater'],
     'cater': ['cater'],
   }

So if the current_word is 'ca' you know that it is a valid prefix because 'ca' in d returns True (so continue the board traversal). And if the current_word is 'cat' then you know that it is a valid word because it is a valid prefix and 'cat' in d['cat'] returns True too.

If felt like this allowed for some readable code that doesn't seem too slow. Like everyone else the expense in this system is reading/building the index. Solving the board is pretty much noise.

The code is at http://gist.github.com/268079. It is intentionally vertical and naive with lots of explicit validity checking because I wanted to understand the problem without crufting it up with a bunch of magic or obscurity.

If you want to just label the data points above the bar, you could use plt.annotate()

My code:

import numpy as np
import matplotlib.pyplot as plt

n = [1,2,3,4,5,]
s = [i**2 for i in n]
line = plt.bar(n,s)
plt.xlabel('Number')
plt.ylabel("Square")

for i in range(len(s)):
    plt.annotate(str(s[i]), xy=(n[i],s[i]), ha='center', va='bottom')

plt.show()

By specifying a horizontal and vertical alignment of 'center' and 'bottom' respectively one can get centered annotations.

After spend a lot time, trying follow these answers actually after code below it worked for me. Before do it just but be sure that there is no problem in update :)

gem update --system

ARGH!

I found it... I didn't have an extra package, called Microsoft.Owin.Host.SystemWeb

Once i searched and installed this, it worked.

Now - i am not sure if i just missed everything, though found NO reference to such a library or package when going through various tutorials. It also didn't get installed when i installed all this Identity framework... Not sure if it were just me..

EDIT Although it's in the Microsoft.Owin.Host.SystemWeb assembly it is an extension method in the System.Web namespace, so you need to have the reference to the former, and be using the latter.

I wrote a nice way of parsing CSV files and I thought I should add it as an answer:

#include <algorithm>
#include <fstream>
#include <iostream>
#include <stdlib.h>
#include <stdio.h>

struct CSVDict
{
  std::vector< std::string > inputImages;
  std::vector< double > inputLabels;
};

/**
\brief Splits the string

\param str String to split
\param delim Delimiter on the basis of which splitting is to be done
\return results Output in the form of vector of strings
*/
std::vector<std::string> stringSplit( const std::string &str, const std::string &delim )
{
  std::vector<std::string> results;

  for (size_t i = 0; i < str.length(); i++)
  {
    std::string tempString = "";
    while ((str[i] != *delim.c_str()) && (i < str.length()))
    {
      tempString += str[i];
      i++;
    }
    results.push_back(tempString);
  }

  return results;
}

/**

2. Delimiters are only used to differentiate cell members

\param csvFileName The full path of the file to parse

std::vector< CSVDict > parseCSVFile( const std::string &csvFileName, const std::string &inputColumns, const std::string &inputLabels, const std::string &delim )
{
  std::vector< CSVDict > return_CSVDict;
  std::vector< std::string > inputColumnsVec = stringSplit(inputColumns, delim), inputLabelsVec = stringSplit(inputLabels, delim);
  std::vector< std::vector< std::string > > returnVector;
  std::ifstream inFile(csvFileName.c_str());
  int row = 0;
  std::vector< size_t > inputColumnIndeces, inputLabelIndeces;
  for (std::string line; std::getline(inFile, line, '\n');)
  {
    CSVDict tempDict;
    std::vector< std::string > rowVec;
    line.erase(std::remove(line.begin(), line.end(), '"'), line.end());
    rowVec = stringSplit(line, delim);

    // for the first row, record the indeces of the inputColumns and inputLabels
    if (row == 0)
    {
      for (size_t i = 0; i < rowVec.size(); i++)
      {
        for (size_t j = 0; j < inputColumnsVec.size(); j++)
        {
          if (rowVec[i] == inputColumnsVec[j])
          {
            inputColumnIndeces.push_back(i);
          }
        }
        for (size_t j = 0; j < inputLabelsVec.size(); j++)
        {
          if (rowVec[i] == inputLabelsVec[j])
          {
            inputLabelIndeces.push_back(i);
          }
        }
      }
    }
    else
    {
      for (size_t i = 0; i < inputColumnIndeces.size(); i++)
      {
        tempDict.inputImages.push_back(rowVec[inputColumnIndeces[i]]);
      }
      for (size_t i = 0; i < inputLabelIndeces.size(); i++)
      {
        double test = std::atof(rowVec[inputLabelIndeces[i]].c_str());
        tempDict.inputLabels.push_back(std::atof(rowVec[inputLabelIndeces[i]].c_str()));
      }
      return_CSVDict.push_back(tempDict);
    }
    row++;
  }

  return return_CSVDict;
}

I have had this problem frequently with multiple concurrent goroutines.

It may or may not be a good pattern, but I define a a struct for my workers with a quit channel and field for the worker state:

type Worker struct {
    data chan struct
    quit chan bool
    stopped bool
}

Then you can have a controller call a stop function for the worker:

func (w *Worker) Stop() {
    w.quit <- true
    w.stopped = true
}

func (w *Worker) eventloop() {
    for {
        if w.Stopped {
            return
        }
        select {
            case d := <-w.data:
                //DO something
                if w.Stopped {
                    return
                }
            case <-w.quit:
                return
        }
    }
}

This gives you a pretty good way to get a clean stop on your workers without anything hanging or generating errors, which is especially good when running in a container.

I found the easiest way is to use the node.js package cors. The simplest usage is:

var cors = require('cors')

var app = express()
app.use(cors())

There are, of course many ways to configure the behaviour to your needs; the page linked above shows a number of examples.

Assuming the ID is unique:

var result = xmldoc.Element("Customers")
                   .Elements("Customer")
                   .Single(x => (int?)x.Attribute("ID") == 2);

You could also use First, FirstOrDefault, SingleOrDefault or Where, instead of Single for different circumstances.

I worked quite a long time with Flux and now quite a long time using Redux. As Dan pointed out both architectures are not so different. The thing is that Redux makes the things simpler and cleaner. It teaches you a couple of things on top of Flux. Like for example Flux is a perfect example of one-direction data flow. Separation of concerns where we have data, its manipulations and view layer separated. In Redux we have the same things but we also learn about immutability and pure functions.

One more related question, since it took me forever to find the answer:

How to make the legend background blank (i.e. transparent, not white):

legend = plt.legend()
legend.get_frame().set_facecolor('none')

Warning, you want 'none' (the string). None means the default color instead.

Really quick and really dirty? This one-liner on the top of your script will work:

[[ $(pgrep -c "`basename \"$0\"`") -gt 1 ]] && exit

Of course, just make sure that your script name is unique. :)

You can try using the below two command and list all Kafka topic

• bin/kafka-topics.sh --describe --zookeeper 192.168.0.142:2181,192.168.9.115:2181,192.168.4.57:2181
• bin/kafka-topics.sh --zookeeper 192.168.0.142:2181,192.168.9.115:2181,192.168.4.57:218 --list

Sometimes I found myself deleting the migration file and then deleting the corresponding entry on the table schema_migrations from the database. Not pretty but it works.

There is pretty concise and easy way:

Response.Write("<script>alert('Your text');</script>");

try:

parent.childNodes[1].style.color = "rgb(155, 102, 102)"; 

Or

parent.childNodes[1].style.color = "#"+(155).toString(16)+(102).toString(16)+(102).toString(16);

Its only possible to get the WSDL if the webservice is configured to deliver it. Therefor you have to specify a serviceBehavior and enable httpGetEnabled:

<serviceBehaviors>
    <behavior name="BindingBehavior">
        <serviceMetadata httpGetEnabled="true" />
        <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
</serviceBehaviors>

In case the webservice is only accessible via https you have to enable httpsGetEnabled instead of httpGetEnabled.

The first is type correct, and correct in some strict sense. (If you think about is, size can never be less than zero.) That warning strikes me as one of the good candidates for being ignored, though.

Instead of having a fat APK file, I would like to use just the armeabi files and remove the armeabi-v7a folder.

The opposite is a much better strategy. If you have minSdkVersion to 14 and upload your apk to the play store, you'll notice you'll support the same number of devices whether you support armeabi or not. Therefore, there are no devices with Android 4 or higher which would benefit from armeabi at all.

This is probably why the Android NDK doesn't even support armeabi anymore as per revision r17b. [source]

Like this

#if defined(LINUX) || defined(ANDROID)

Your query should work for synonyms as well as the tables. However, you seem to expect indexes on views where there are not. Maybe is it materialized views ?

Filling a DataSet with multiple tables can be done by sending multiple requests to the database, or in a faster way: Multiple SELECT statements can be sent to the database server in a single request. The problem here is that the tables generated from the queries have automatic names Table and Table1. However, the generated table names can be mapped to names that should be used in the DataSet.

SqlDataAdapter adapter = new SqlDataAdapter(
      "SELECT * FROM Customers; SELECT * FROM Orders", connection);
adapter.TableMappings.Add("Table", "Customer");
adapter.TableMappings.Add("Table1", "Order");

adapter.Fill(ds);

While there are suggestions above for "doing it the python way", if one wants to really have a logic based on EOF, then I suppose using exception handling is the way to do it --

try:
    line = raw_input()
    ... whatever needs to be done incase of no EOF ...
except EOFError:
    ... whatever needs to be done incase of EOF ...

Example:

$ echo test | python -c "while True: print raw_input()"
test
Traceback (most recent call last):
  File "<string>", line 1, in <module> 
EOFError: EOF when reading a line

Or press Ctrl-Z at a raw_input() prompt (Windows, Ctrl-Z Linux)

I went with using the regex from detectmobilebrowser.com to check against the user-agent string. Even tho it says it was last updated in 2014 it was accurate on the devices I tested.

A quick search on google code gives (it uses formula from @Mark Byers's answer):

def choose(n, k):
    """
    A fast way to calculate binomial coefficients by Andrew Dalke (contrib).
    """
    if 0 <= k <= n:
        ntok = 1
        ktok = 1
        for t in xrange(1, min(k, n - k) + 1):
            ntok *= n
            ktok *= t
            n -= 1
        return ntok // ktok
    else:
        return 0

choose() is 10 times faster (tested on all 0 <= (n,k) < 1e3 pairs) than scipy.misc.comb() if you need an exact answer.

def comb(N,k): # from scipy.comb(), but MODIFIED!
    if (k > N) or (N < 0) or (k < 0):
        return 0L
    N,k = map(long,(N,k))
    top = N
    val = 1L
    while (top > (N-k)):
        val *= top
        top -= 1
    n = 1L
    while (n < k+1L):
        val /= n
        n += 1
    return val

When using Python >= 3.6, the cleanest way is to use f-strings with string formatting:

>>> var = 23
>>> f"{var:#010b}"
'0b00010111'

Explanation:

• var the variable to format
• : everything after this is the format specifier
• # use the alternative form (adds the 0b prefix)
• 0 pad with zeros
• 10 pad to a total length off 10 (this includes the 2 chars for 0b)
• b use binary representation for the number

I got this error with a mis-configured test event. I changed the source buckets ARN but forgot to edit the default S3 bucket name.

I.e. make sure that in the bucket section of the test event both the ARN and bucket name are set correctly:

"bucket": {
  "arn": "arn:aws:s3:::your_bucket_name",
  "name": "your_bucket_name",
  "ownerIdentity": {
    "principalId": "EXAMPLE"
  }

Another solution that doesn't require changing your existing code:

import Queue             # Python 2.x
#from queue import Queue # Python 3.x

from threading import Thread

def foo(bar):
    print 'hello {0}'.format(bar)
    return 'foo'

que = Queue.Queue()      # Python 2.x
#que = Queue()           # Python 3.x

t = Thread(target=lambda q, arg1: q.put(foo(arg1)), args=(que, 'world!'))
t.start()
t.join()
result = que.get()
print result

It can be also easily adjusted to a multi-threaded environment:

import Queue             # Python 2.x
#from queue import Queue # Python 3.x
from threading import Thread

def foo(bar):
    print 'hello {0}'.format(bar)
    return 'foo'

que = Queue.Queue()      # Python 2.x
#que = Queue()           # Python 3.x

threads_list = list()

t = Thread(target=lambda q, arg1: q.put(foo(arg1)), args=(que, 'world!'))
t.start()
threads_list.append(t)

# Add more threads here
...
threads_list.append(t2)
...
threads_list.append(t3)
...

# Join all the threads
for t in threads_list:
    t.join()

# Check thread's return value
while not que.empty():
    result = que.get()
    print result

Use @Arkaitz Jimenez's code to get two timevals:

#include <sys/time.h>
//...
struct timeval tv1, tv2, diff;

// get the first time:
gettimeofday(&tv1, NULL);

// do whatever it is you want to time
// ...

// get the second time:
gettimeofday(&tv2, NULL);

// get the difference:

int result = timeval_subtract(&diff, &tv1, &tv2);

// the difference is storid in diff now.

Sample code for timeval_subtract can be found at this web site:

 /* Subtract the `struct timeval' values X and Y,
    storing the result in RESULT.
    Return 1 if the difference is negative, otherwise 0.  */

 int
 timeval_subtract (result, x, y)
      struct timeval *result, *x, *y;
 {
   /* Perform the carry for the later subtraction by updating y. */
   if (x->tv_usec < y->tv_usec) {
     int nsec = (y->tv_usec - x->tv_usec) / 1000000 + 1;
     y->tv_usec -= 1000000 * nsec;
     y->tv_sec += nsec;
   }
   if (x->tv_usec - y->tv_usec > 1000000) {
     int nsec = (x->tv_usec - y->tv_usec) / 1000000;
     y->tv_usec += 1000000 * nsec;
     y->tv_sec -= nsec;
   }

   /* Compute the time remaining to wait.
      tv_usec is certainly positive. */
   result->tv_sec = x->tv_sec - y->tv_sec;
   result->tv_usec = x->tv_usec - y->tv_usec;

   /* Return 1 if result is negative. */
   return x->tv_sec < y->tv_sec;
 }

function arrayDuplicateRemove(arr){
    var c = 0;
    var tempArray = [];
    console.log(arr);
    arr.sort();
    console.log(arr);
    for (var i = arr.length - 1; i >= 0; i--) {
        if(arr[i] != tempArray[c-1]){
            tempArray.push(arr[i])
            c++;
        }
    };
    console.log(tempArray);

You can connect to a AWS ec-2 instance using the following commands.

chmod 400 mykey.pem

ssh -i mykey.pem username@your-ip

by default the machine name usually be like ubuntu since usually ubuntu machine is used as a server so the following command will work in that case.

ssh -i mykey.pem ubuntu@your-ip

Here's a blog post explains it very well:

http://panks.me/posts/2013/11/install-gdb-on-os-x-mavericks-from-source/

And the way I get it working:

1. Create a coding signing certificate via KeyChain Access:

   1.1 From the Menu, select KeyChain Access > Certificate Assistant > Create a Certificate...

   1.2 Follow the wizard to create a certificate and let's name it gdb-cert, the Identity Type is Self Signed Root, and the Certificate Type is Code Signing and select the Let me override defaults.

   1.3 Click several times on Continue until you get to the Specify a Location For The Certificate screen, then set Keychain to System.

2. Install gdb via Homebrew: brew install gdb

3. Restart taskgated: sudo killall taskgated && exit

4. Reopen a Terminal window and type sudo codesign -vfs gdb-cert /usr/local/bin/gdb

Working code in Swift-4.2

import UIKit
import EventKit
import EventKitUI

class yourViewController: UIViewController{

    let eventStore = EKEventStore()

    func addEventToCalendar() {

    eventStore.requestAccess( to: EKEntityType.event, completion:{(granted, error) in
        DispatchQueue.main.async {
            if (granted) && (error == nil) {
                let event = EKEvent(eventStore: self.eventStore)
                event.title = self.headerDescription
                event.startDate = self.parse(self.requestDetails.value(forKey: "session_time") as? String ?? "")
                event.endDate = self.parse(self.requestDetails.value(forKey: "session_end_time") as? String ?? "")
                let eventController = EKEventEditViewController()
                eventController.event = event
                eventController.eventStore = self.eventStore
                eventController.editViewDelegate = self
                self.present(eventController, animated: true, completion: nil)

            }
        }


       })
    }

}

Now we will get the event screen and here you can also modify your settings:

Now add delegate method to handle Cancel and add the event button action of event screen:

    extension viewController: EKEventEditViewDelegate {

    func eventEditViewController(_ controller: EKEventEditViewController, didCompleteWith action: EKEventEditViewAction) {
        controller.dismiss(animated: true, completion: nil)

you can also try

git show <filename>

For commits, git show will show the log message and textual diff (between your file and the commited version of the file).

You can check git show Documentation for more info.

Emulator:

Consider a situation that you know only English and you are in China. In order to interact with a Chinese person you need a translator. Now, role of translator is that it will seek input from you in English and convert to Chinese and and give that input to the Chinese person and gets response from the Chinese person and convert to English and give the output to you in English. Now that translator and Chinese person is the emulator. Both combine will provide similar functionality as if you were communicating with the English person. So hardware may be different but functionality will be same.

Simulator:

I can't give better example than SPICE or flight simulator. Both will replace hardware component behavior with the software or mathematical model which will behave similar to the hardware.

In the end it depends on the context that which solution better suits project needs.

In case you actually mean what you seem to ask, I'll provide this alternative answer.

You say you want the dict to return a specified value, you do not say you want to set that value at the same time, like defaultdict does. This will do so:

class DictWithDefault(dict):
    def __init__(self, default, **kwargs):
        self.default = default
        super(DictWithDefault, self).__init__(**kwargs)

    def __getitem__(self, key):
        if key in self:
            return super(DictWithDefault, self).__getitem__(key)
        return self.default

Use like this:

d = DictWIthDefault(99, x=5, y=3)
print d["x"]   # 5
print d[42]    # 99
42 in d        # False
d[42] = 3
42 in d        # True

Alternatively, you can use a standard dict like this:

d = {3: 9, 4: 2}
default = 99
print d.get(3, default)  # 9
print d.get(42, default) # 99

Kotlin's String class has a format function now, which internally uses Java's String.format method:

/**
 * Uses this string as a format string and returns a string obtained by substituting the specified arguments,
 * using the default locale.
 */
@kotlin.internal.InlineOnly
public inline fun String.Companion.format(format: String, vararg args: Any?): String = java.lang.String.format(format, *args)

Usage

val pi = 3.14159265358979323
val formatted = String.format("%.2f", pi) ;
println(formatted)
>>3.14

I'm currently experimenting with canvas and pixels... I'm finding this logic works out for me better.

1. Use this to calculate the grey-ness ( luma ? )
2. but with both the existing value and the new 'tint' value
3. calculate the difference ( I found I did not need to multiply )

4. add to offset the 'tint' value

   var grey =  (r + g + b) / 3;    
   var grey2 = (new_r + new_g + new_b) / 3;
   
   var dr =  grey - grey2 * 1;    
   var dg =  grey - grey2 * 1    
   var db =  grey - grey2 * 1;  
   
   tint_r = new_r + dr;    
   tint_g = new_g + dg;   
   tint_b = new_b _ db;
   

or something like that...

Ipaper::geom_boxplot2 is just what you want.

# devtools::install_github('kongdd/Ipaper')
library(Ipaper)
library(ggplot2)
p <- ggplot(mpg, aes(class, hwy))
p + geom_boxplot2(width = 0.8, width.errorbar = 0.5)

Simplest way using Jquery

Just add this:

<script src="https://cdn.jsdelivr.net/gh/linways/[email protected]/dist/tableToExcel.js"></script>

Then add Jquery script:

<script type="text/javascript">
  $(document).ready(function () {
      $("#exportBtn1").click(function(){
        TableToExcel.convert(document.getElementById("tab1"), {
            name: "Traceability.xlsx",
            sheet: {
            name: "Sheet1"
            }
          });
        });
  });
</script>

Then add HTML button:

<button id="exportBtn1">Export To Excel</button><br><br>

Note: "exportBtn1" will be button ID and "tab1" will be table ID

I had this error because of some typo in an alias of a column that contained a questionmark (e.g. contract.reference as contract?ref)

If you try exec sp_rename and receieve a LockMatchID error then it might help to add a use [database] statement first:

I tried

 exec sp_rename '[database_name].[dbo].[table_name]', 'new_table_name';
 -- Invalid EXECUTE statement using object "Object", method "LockMatchID".

What I had to do to fix it was to rewrite it to:

use database_name
exec sp_rename '[dbo].[table_name]', 'new_table_name';

A super simple way using URLSearchParams.

function getParam(param){
  return new URLSearchParams(window.location.search).get(param);
}

It's currently supported in Chrome, Firefox, Safari, Edge, and others.

Both of the previous 2 answers have at least O(n) time complexity and the string conversion has O(n) space complexity too. Here's a solution for constant time and space:

num // 10 ** (int(math.log(num, 10)) - 1)

Function:

import math

def first_n_digits(num, n):
    return num // 10 ** (int(math.log(num, 10)) - n + 1)

Output:

>>> first_n_digits(123456, 1)
1
>>> first_n_digits(123456, 2)
12
>>> first_n_digits(123456, 3)
123
>>> first_n_digits(123456, 4)
1234
>>> first_n_digits(123456, 5)
12345
>>> first_n_digits(123456, 6)
123456

You will need to add some checks if it's possible that your input number has less digits than you want.

If you are willing to use Three20 framework, it has a category on NSString that adds stringByRemovingHTMLTags method. See NSStringAdditions.h in Three20Core subproject.

You can use Optional in functional style to avoid NullPointerException and ArrayIndexOutOfBoundsException :

String[] array = new String[]{"aaa", null, "ccc"};
for (int i = 0; i < 4; i++) {
    String result = Optional.ofNullable(array.length > i ? array[i] : null)
            .map(x -> x.toUpperCase()) //some operation here
            .orElse("NO_DATA");
    System.out.println(result);
}

Output:

AAA
NO_DATA
CCC
NO_DATA

use "rb" to open a binary file. Then the bytes of the file won't be encoded when you read them

With library fpp, you can easily create time series with date format: time_ser=ts(data,frequency=4,start=c(1954,2))

here we start at the 2nd quarter of 1954 with quarter fequency.

If you are programming in PHP, it is useful to split lines by \n and then trim() each line (provided you don't care about whitespace) to give you a "clean" line regardless.

foreach($line in explode("\n", $data))
{
    $line = trim($line);
    ...
}

Once I found what format it was looking for in the connection string, it worked just fine like this with Oracle.ManagedDataAccess. Without having to mess around with anything separately.

DATA SOURCE=DSDSDS:1521/ORCL;

This is how I achieved the same in Scala. I am not sure if it is more efficient than the valid answer, but it requires less coding

val parquetFileDF = sqlContext.read.parquet("myParquetFule.parquet")

val myRow7th = parquetFileDF.rdd.take(7).last

If you have mounted a second drive to an NTFS folder as a 'mounted volume' then you can get this issue.

Move you files to a drive location outside of the mounted volume.

To redirect in php:

<?php header('Location: URL'); exit; ?>

For char or short to int, you just need to assign the value.

char ch = 16;
int in = ch;

Same to int64.

long long lo = ch;

All values will be 16.

If anyone wants to enable dark mode, you may follow the below steps

• Open your Notepad++, and select “Settings” on the menu bar, and choose “Style configurator”.
• Select theme “Obsidian” (you can choose other dark themes)
• Click on Save&Colse

You must to wrap your following code into a block (Either method or static).

BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("What is your name?");
String name = in.readLine(); ;
System.out.println("Hello " + name);

Without a block you can only declare variables and more than that assign them a value in single statement.

For method main() will be best choice for now:

public class details {
    public static void main(String[] args){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or If you want to use static block then...

public class details {
    static {
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

or if you want to build another method then..

public class details {
    public static void main(String[] args){
        myMethod();
    }
    private static void myMethod(){
        BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("What is your name?");
        String name = in.readLine(); ;
        System.out.println("Hello " + name);
    }
}

Also worry about exception due to BufferedReader .

Do not do it. I might want to run my car on monkey blood. I have my reasons, but sometimes it's better to stick with using things the way they were designed even if it doesn't "absolutely perfectly" match the exact look you are driving for.

To back up my argument I submit the following.

• See how this image lacks the status bar at the bottom. This link is using the onclick="location.href" model. (This is a real-life production example from my predecessor) This can make users hesitant to click on the link, since they have no idea where it is taking them, for starters.

You are also making Search engine optimization more difficult IMO as well as making the debugging and reading of your code/HTML more complex. A submit button should submit a form. Why should you(the development community) try to create a non-standard UI?

I assume you have your JS file declared inside the <head> tag so it keeps it consistent, like standard, then in your JS make sure the canvas initialization is after the page is loaded:

window.onload = function () {
    var myCanvas = document.getElementById('canvas');
    var ctx = myCanvas.getContext('2d');
}

There is no need to use jQuery just to initialize a canvas, it's very evident most of the programmers all around the world use it unnecessarily and the accepted answer is a probe of that.

#pragma mark directives show up in Xcode in the menus for direct access to methods. They have no impact on the program at all.

For example, using it with Xcode 4 will make those items appear directly in the Jump Bar.

There is a special pragma mark - which creates a line.

public static void ClearLine(int lines = 1)
{
    for (int i = 1; i <= lines; i++)
    {
        Console.SetCursorPosition(0, Console.CursorTop - 1);
        Console.Write(new string(' ', Console.WindowWidth));
        Console.SetCursorPosition(0, Console.CursorTop - 1);
    }
}

from package.A import foo

I think it's clearer than

import sys
sys.path.append("..")

the split() method takes a regular expression as an argument

I just came across this as a really nice and elegant solution:

Math.random().toString(36).slice(2)

Notes on this implementation:

• This will produce a string anywhere between zero and 12 characters long, usually 11 characters, due to the fact that floating point stringification removes trailing zeros.
• It won't generate capital letters, only lower-case and numbers.
• Because the randomness comes from Math.random(), the output may be predictable and therefore not necessarily unique.
• Even assuming an ideal implementation, the output has at most 52 bits of entropy, which means you can expect a duplicate after around 70M strings generated.

You can declare as many Exceptions as you want for your interface method. But the class you gave in your question is invalid. It should read

public class MyClass implements MyInterface {
  public void find(int x) throws A_Exception, B_Exception{
    ----
    ----
    ---
  }
}

Then an interface would look like this

public interface MyInterface {
  void find(int x) throws A_Exception, B_Exception;
}

You can do this by using asynchronous Javascript SDK provided by facebook

Have a look at the following code

FB Javascript SDK initialization

<div id="fb-root"></div>
<script>
window.fbAsyncInit = function() {
FB.init({appId: 'YOUR APP ID', status: true, cookie: true,
xfbml: true});
};
(function() {
var e = document.createElement('script'); e.async = true;
e.src = document.location.protocol +
'//connect.facebook.net/en_US/all.js';
document.getElementById('fb-root').appendChild(e);
}());
</script>

Note: Remember to replace YOUR APP ID with your facebook AppId. If you don't have facebook AppId and you don't know how to create please check this

Add JQuery Library, I would preferred Google Library

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" type="text/javascript"></script>

Add share dialog box (You can customize this dialog box by setting up parameters

<script type="text/javascript">
$(document).ready(function(){
$('#share_button').click(function(e){
e.preventDefault();
FB.ui(
{
method: 'feed',
name: 'This is the content of the "name" field.',
link: 'http://www.groupstudy.in/articlePost.php?id=A_111213073144',
picture: 'http://www.groupstudy.in/img/logo3.jpeg',
caption: 'Top 3 reasons why you should care about your finance',
description: "What happens when you don't take care of your finances? Just look at our country -- you spend irresponsibly, get in debt up to your eyeballs, and stress about how you're going to make ends meet. The difference is that you don't have a glut of taxpayers…",
message: ""
});
});
});
</script>

Now finally add image button

<img src = "share_button.png" id = "share_button">

Maybe use in between better. It worked for me to get range then filter it

Late answer, but this is the only option that actually worked for me:

(echo file '1.mp4' & echo file '2.mp4' & echo file '3.mp4' & echo file '4.mp4') | ffmpeg -protocol_whitelist file,pipe -f concat -safe 0 -i pipe: -vcodec copy -acodec copy "coNvid19.mp4"

This is because you are referring to property of controller named HttpContext. To access the current context use full class name:

System.Web.HttpContext.Current

However this is highly not recommended to access context like this in ASP.NET MVC, so yes, you can think of System.Web.HttpContext.Current as being deprecated inside ASP.NET MVC. The correct way to access current context is

this.ControllerContext.HttpContext

or if you are inside a Controller, just use member

this.HttpContext

I'm always forgetting how to do this because it's something that I just do once in a while, this is one possible solution, and it just works:

1. Go to your favourite browser and download the main certificate from the secured website.

2. Execute the two following lines of code:

   $ openssl x509 -outform der -in GlobalSignRootCA.crt -out GlobalSignRootCA.der
   $ keytool -import -alias GlobalSignRootCA -keystore GlobalSignRootCA.jks -file GlobalSignRootCA.der
   

3. If executing in Java SE environment add the following options:

   $ java -Djavax.net.ssl.trustStore=GlobalSignRootCA.jks -Djavax.net.ssl.trustStorePassword=trustStorePassword -jar MyJar.jar
   

4. Or add the following to the java code:

   System.setProperty("javax.net.ssl.trustStore", "GlobalSignRootCA.jks");
   System.setProperty("javax.net.ssl.trustStorePassword","trustStorePassword");
   

The other option for step 2 is to just using the keytool command. Bellow is an example with a chain of certificates:

$ keytool -import -file org.eu.crt -alias orgcrt -keystore globalsignrs.jks
$ keytool -import -file GlobalSignOrganizationValidationCA-SHA256-G2.crt -alias globalsignorgvalca -keystore globalsignrs.jks
$ keytool -import -file GlobalSignRootCA.crt -alias globalsignrootca -keystore globalsignrs.jks

You need to import the module datetime first:

>>> import datetime

After that it works:

>>> import datetime
>>> date = datetime.date.today()
>>> date
datetime.date(2013, 11, 12)

Just looking for the right place to put this piece of code.

let's say you have the following property:

[Display(Name = "Solar Radiation (Average)", ShortName = "SolarRadiationAvg")]
public int SolarRadiationAvgSensorId { get; set; }

And you want to get the ShortName value. You can do:

((DisplayAttribute)(typeof(SensorsModel).GetProperty(SolarRadiationAvgSensorId).GetCustomAttribute(typeof(DisplayAttribute)))).ShortName;

Or to make it general:

internal static string GetPropertyAttributeShortName(string propertyName)
{
    return ((DisplayAttribute)(typeof(SensorsModel).GetProperty(propertyName).GetCustomAttribute(typeof(DisplayAttribute)))).ShortName;
}

In addition to the answer of Dyppl, I think it would be nice to place this inside the OnDataContextChanged event:

private void OnDataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
{
    // Unforunately we cannot bind from the viewmodel to the code behind so easily, the dependency property is not available in XAML. (for some reason).
    // To work around this, we create the binding once we get the viewmodel through the datacontext.
    var newViewModel = e.NewValue as MyViewModel;

    var executablePathBinding = new Binding
    {
        Source = newViewModel,
        Path = new PropertyPath(nameof(newViewModel.ExecutablePath))
    };

    BindingOperations.SetBinding(LayoutRoot, ExecutablePathProperty, executablePathBinding);
}

We have also had cases were we just saved the DataContext to a local property and used that to access viewmodel properties. The choice is of course yours, I like this approach because it is more consistent with the rest. You can also add some validation, like null checks. If you actually change your DataContext around, I think it would be nice to also call:

BindingOperations.ClearBinding(myText, TextBlock.TextProperty);

to clear the binding of the old viewmodel (e.oldValue in the event handler).

Above Code JAVA version: Thanks @William

public static List<Rect> detectLetters(Mat img){    
    List<Rect> boundRect=new ArrayList<>();

    Mat img_gray =new Mat(), img_sobel=new Mat(), img_threshold=new Mat(), element=new Mat();
    Imgproc.cvtColor(img, img_gray, Imgproc.COLOR_RGB2GRAY);
    Imgproc.Sobel(img_gray, img_sobel, CvType.CV_8U, 1, 0, 3, 1, 0, Core.BORDER_DEFAULT);
    //at src, Mat dst, double thresh, double maxval, int type
    Imgproc.threshold(img_sobel, img_threshold, 0, 255, 8);
    element=Imgproc.getStructuringElement(Imgproc.MORPH_RECT, new Size(15,5));
    Imgproc.morphologyEx(img_threshold, img_threshold, Imgproc.MORPH_CLOSE, element);
    List<MatOfPoint> contours = new ArrayList<MatOfPoint>();
    Mat hierarchy = new Mat();
    Imgproc.findContours(img_threshold, contours,hierarchy, 0, 1);

    List<MatOfPoint> contours_poly = new ArrayList<MatOfPoint>(contours.size());

     for( int i = 0; i < contours.size(); i++ ){             

         MatOfPoint2f  mMOP2f1=new MatOfPoint2f();
         MatOfPoint2f  mMOP2f2=new MatOfPoint2f();

         contours.get(i).convertTo(mMOP2f1, CvType.CV_32FC2);
         Imgproc.approxPolyDP(mMOP2f1, mMOP2f2, 2, true); 
         mMOP2f2.convertTo(contours.get(i), CvType.CV_32S);


            Rect appRect = Imgproc.boundingRect(contours.get(i));
            if (appRect.width>appRect.height) {
                boundRect.add(appRect);
            }
     }

    return boundRect;
}

And use this code in practice :

        System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
        Mat img1=Imgcodecs.imread("abc.png");
        List<Rect> letterBBoxes1=Utils.detectLetters(img1);

        for(int i=0; i< letterBBoxes1.size(); i++)
            Imgproc.rectangle(img1,letterBBoxes1.get(i).br(), letterBBoxes1.get(i).tl(),new Scalar(0,255,0),3,8,0);         
        Imgcodecs.imwrite("abc1.png", img1);

Although you may have already found a resolution to your issue, I'm still going to post this note to benefit someone else. I ran into a similar issue. I basically used a different domain account to test and compare. The task ran just fine with "Run whether user is logged on or not" checked.

A couple of things to keep in mind and make sure of:

1. The account being use to execute task must have "Logon as batch job" rights under the local security policy of the server (or be member of local Admin group). You must specified the account you need to run scripts/bat files.
2. Make sure you are entering the correct password characters
3. Tasks in 2008 R2 don't run interactively specially if you run them as "Run whether user is logged on or not". This will likely fail specially if on the script you are looking for any objects\resource specific to a user-profile when the task was created as the powershell session will need that info to start, otherwise it will start and immediately end. As an example for defining $Path when running script as "Run whether user is logged on or not" and I specify a mapped drive. It would look for that drive when the task kicks off, but since the user account validated to run task is not logged in and on the script you are referring back to a source\object that it needs to work against it is not present task will just terminate. mapped drive (\server\share) x:\ vs. Actual UNC path \server\share
4. Review your steps, script, arguments. Sometimes the smallest piece can make a big difference even if you have done this process many times. I have missed several times a character when entering the password or a semi-colon sometimes when building script or task.

Check this link and hopefully you or someone else can benefit from this info: https://technet.microsoft.com/en-us/library/cc722152.aspx

The easiest way to get rid of the the ugly frame in newer versions of matplotlib:

import matplotlib.pyplot as plt
plt.box(False)

If you really must always use the object oriented approach, then do: ax.set_frame_on(False).

Change the window name in your two different calls:

function popitup(url,windowName) {
       newwindow=window.open(url,windowName,'height=200,width=150');
       if (window.focus) {newwindow.focus()}
       return false;
     }

windowName must be unique when you open a new window with same url otherwise the same window will be refreshed.

my case was a little different - unintentionally I have changed owner of git repository (project.git directory in my case), changing owner back to the git user helped

The BrightCloud web service API is perfect for this. It's a REST API for doing website lookups just like this. It contains a very large and very accurate web filtering DB and one of the categories, Adult, has over 10M porn sites identified!

@nCdy: index_of_cell should be replaced by an integer, corresponding to the index number of the cell that you wish to hide in the .Cells collection.

For example, suppose that your GridView presents the following columns:

CONTACT NAME | CONTACT NUMBER | CUSTOMERID | ADDRESS LINE 1 | POST CODE

And you want the CUSTOMERID column not to be displayed. Since collections indexes are 0-based, your CUSTOMERID column's index is..........? That's right, 2!! Very good. Now... guess what you should put in there, to replace 'index_of_cell'??

To solve this either you down-grade the Django to any version lesser than 2.0. pip install Django==1.11.29.

Suppose that if you have an application with many users and you have defined a static function that saves state within a static variable, then every user will modify the state of other users.

You could use the DateTime class as well:

$timestamp = mktime(15, 30, 00, 3, 28, 2015);

$d = new DateTime();
$d->setTimestamp($timestamp);

Add a Period of 1 Day:

$d->add(new DateInterval('P1D'));
echo $d->format('c');

See DateInterval for more details.

I tried to add another join(), and it seems worked. Here is code

from threading import Thread

I realize this is a very old post and has some great answers already, but I wanted to make a simple MCVE to demonstrate one such approach and allow new coders a way to quickly see the concept in action.

In this example, we will use 5 files:

1. Main.java - Simply used to start the application and call the first controller.
2. Controller1.java - The controller for the first FXML layout.
3. Controller2.java - The controller for the second FXML layout.
4. Layout1.fxml - The FXML layout for the first scene.
5. Layout2.fxml - The FXML layout for the second scene.

All files are listed in their entirety at the bottom of this post.

The Goal: To demonstrate passing values from Controller1 to Controller2 and vice versa.

The Program Flow:

• The first scene contains a TextField, a Button, and a Label. When the Button is clicked, the second window is loaded and displayed, including the text entered in the TextField.
• Within the second scene, there is also a TextField, a Button, and a Label. The Label will display the text entered in the TextField on the first scene.
• Upon entering text in the second scene's TextField and clicking its Button, the first scene's Label is updated to show the entered text.

This is a very simple demonstration and could surely stand for some improvement, but should make the concept very clear.

The code itself is also commented with some details of what is happening and how.

THE CODE

Main.java:

import javafx.application.Application;
import javafx.stage.Stage;

public class Main extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) {

        // Create the first controller, which loads Layout1.fxml within its own constructor
        Controller1 controller1 = new Controller1();

        controller2.showStage();

    }

     */

    public Controller2(Controller1 controller1) {

Define the following function (not mine, not sure where I found it long ago):

private static String convertStreamToString(InputStream is) {

BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();

String line = null;
try {
    while ((line = reader.readLine()) != null) {
        sb.append(line + "\n");
    }
} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        is.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
return sb.toString();

}

Then:

String jsonReply;
if(conn.getResponseCode()==201 || conn.getResponseCode()==200)
    {
        success = true;
        InputStream response = conn.getInputStream();
        jsonReply = convertStreamToString(response);

        // Do JSON handling here....
    }

You need to enable deep object dirty checking. By default angular only checks the reference of the top level variable that you watch.

App.directive('d3Visualization', function() {
    return {
        restrict: 'E',
        scope: {
            val: '='
        },
        link: function(scope, element, attrs) {
            scope.$watch('val', function(newValue, oldValue) {
                if (newValue)
                    console.log("I see a data change!");
            }, true);
        }
    }
});

see Scope. The third parameter of the $watch function enables deep dirty checking if it's set to true.

Take note that deep dirty checking is expensive. So if you just need to watch the children array instead of the whole data variable the watch the variable directly.

scope.$watch('val.children', function(newValue, oldValue) {}, true);

version 1.2.x introduced $watchCollection

Shallow watches the properties of an object and fires whenever any of the properties change (for arrays, this implies watching the array items; for object maps, this implies watching the properties)

scope.$watchCollection('val.children', function(newValue, oldValue) {});

Pure javascript solution with scrollIntoView() function:

document.getElementById('title1').scrollIntoView({block: 'start', behavior: 'smooth'});

<h2 id="title1">Some title</h2>

P.S. 'smooth' parameter now works from Chrome 61 as julien_c mentioned in the comments.

This code:

$monthly_index = array_shift(unpack('H*', date('m/Y')));

Need to be changed into:

$date_time = date('m/Y');
$unpack = unpack('H*', $date_time);
array_shift($unpack);

You can add #define uAppDelegate (AppDelegate *)[[UIApplication sharedApplication] delegate] in your project's Prefix.pch file and then call any method of your AppDelegate in any UIViewController with the below code.

[uAppDelegate showLoginView];

Try creating another full backup after you backup the log w/ truncate_only (IIRC you should do this anyway to maintain the log chain). In simple recovery mode, your log shouldn't grow much anyway since it's effectively truncated after every transaction. Then try specifying the size you want the logfile to be, e.g.

-- shrink log file to c. 1 GB
DBCC SHRINKFILE (Wxlog0, 1000);

The TRUNCATEONLY option doesn't rearrange the pages inside the log file, so you might have an active page at the "end" of your file, which could prevent it from being shrunk.

You can also use DBCC SQLPERF(LOGSPACE) to make sure that there really is space in the log file to be freed.
