The Maven profile and the Spring profile are two completely different things. Your pom.xml defines spring.profiles.active variable which is available in the build process, but not at runtime. That is why only the default profile is activated.

How to bind Maven profile with Spring?

You need to pass the build variable to your application so that it is available when it is started.

1. Define a placeholder in your application.properties:

   [email protected]@
   

   The @spring.profiles.active@ variable must match the declared property from the Maven profile.

2. Enable resource filtering in you pom.xml:

   <build>
       <resources>
           <resource>
               <directory>src/main/resources</directory>
               <filtering>true</filtering>
           </resource>
       </resources>
       …
   </build>
   

   When the build is executed, all files in the src/main/resources directory will be processed by Maven and the placeholder in your application.properties will be replaced with the variable you defined in your Maven profile.

For more details you can go to my post where I described this use case.

Yo could also set labels = FALSE inside axis(...) and print the labels in a separate command with Text. With this option you can rotate the text the text in case you need it

lablist<-as.vector(c(1:10))
axis(1, at=seq(1, 10, by=1), labels = FALSE)
text(seq(1, 10, by=1), par("usr")[3] - 0.2, labels = lablist, srt = 45, pos = 1, xpd = TRUE)

Detailed explanation here

For most multiline strings using an XML element with an inner CDATA block is easier to avoid having to escape anything for simple raw string data.

Dim s as string = <s><![CDATA[Line 1
line 2
line 3]]></s>.Value

Note that I've seen many people state the same format but without the wrapping "< s >" tag (just the CDATA block) but visual studio Automatic formatting seams to alter the leading whitespace of each line then. I think this is due to the object inheritance structure behind the Linq "X" objects. CDATA is not a "Container", the outer block is an XElement which inherits from XContainer.

I tryed most of the previous solutions, and still had the problem. This is what I did next:

• Removed the application from Eclipse
• Stoped the server
• Delete the application folder from webapps
• Delete content from the temp folder in the server
• Delete content from the work folder in the server
• Re-open the application on Eclipse
• Start the server

May be some of this steps are not needed, but "just in case".

So if the previous solutions still not work for you. Try this. I hope it helps ;-)

I personally find it easier use MySQL event scheduler than cron.

Enable it with

SET GLOBAL event_scheduler = ON;

and create an event like this:

CREATE EVENT name_of_event
ON SCHEDULE EVERY 1 DAY
STARTS '2014-01-18 00:00:00'
DO
DELETE FROM tbl_message WHERE DATEDIFF( NOW( ) ,  timestamp ) >=7;

and that's it.

Read more about the syntax here and here is more general information about it.

This is an old question, but comes out high in my Google search for 'perl merge hashes' - and yet it does not mention the very helpful CPAN module Hash::Merge

While this is slightly off-topic, since people will find this by searching for "percentage sign in Python" (as I did), I wanted to note that the % sign is also used to prefix a "magic" function in iPython: https://ipython.org/ipython-doc/3/interactive/tutorial.html#magic-functions

You can easily use the "ng-device-detector" module.

https://github.com/srfrnk/ng-device-detector

var app = angular.module('myapp', ["ng.deviceDetector"]);
app.controller('DeviceCtrl', ["$scope","deviceDetector",function($scope,deviceDetector) {
      console.log("browser: ", deviceDetector.browser);
      console.log("browser version: ", deviceDetector.browser_version);
      console.log("device: ", deviceDetector.device);
}]);

Short and sweet.

[].reduce($('.x'), function(i,v) {return i+v.outerHTML}, '')

or event more sweet with help of arrow functions

[].reduce.call($('.x'), (i,v) => i+v.outerHTML, '')

or without jQuery at all

[].reduce.call(document.querySelectorAll('.x'), (i,v) => i+v.outerHTML, '')

or if you don't like this approach, check that

$('.x').get().reduce((i,v) => i+v.outerHTML, '')

If you want to change the statusBar's color to white, for all of the views contained in a UINavigationController, add this inside AppDelegate:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.

    UINavigationBar.appearance().barStyle = .blackOpaque
    return true
}

This code:

override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

does not work for UIViewControllers contained in a UINavigationController, because the compiler looks for the statusBarStyle of the UINavigationController, not for the statusBarStyle of the ViewControllers contained by it.

Hope this helps those who haven't succeeded with the accepted answer!

I think this is the closest you can get to a simple swap, but it does not have a straightforward usage pattern:

int swap(int a, int b) {  // usage: y = swap(x, x=y);
   return a;
}

y = swap(x, x=y);

It relies on the fact that x will pass into swap before y is assigned to x, then x is returned and assigned to y.

You can make it generic and swap any number of objects of the same type:

<T> T swap(T... args) {   // usage: z = swap(a, a=b, b=c, ... y=z);
    return args[0];
}

c = swap(a, a=b, b=c)

When spring instantiates beans, it looks for a couple of interfaces like ApplicationContextAware and InitializingBean. If they are found, the methods are invoked. E.g. (very simplified)

Class<?> beanClass = beanDefinition.getClass();
Object bean = beanClass.newInstance();
if (bean instanceof ApplicationContextAware) {
    ((ApplicationContextAware) bean).setApplicationContext(ctx);
}

Note that in newer version it may be better to use annotations, rather than implementing spring-specific interfaces. Now you can simply use:

@Inject // or @Autowired
private ApplicationContext ctx;

Worked with this command

python -m pip install --user --upgrade pip

I had to use Debug.print instead of Print, which works in the Immediate window.

More compact version working with spaces and newlines in the file name:

find . -iname '*.txt' -exec sh -c 'echo "{}" ; ls -l "{}"' \;

i also faced similar issue. I could able to solve this by setting JAVA_HOME in Environment variable in windows. Setting JAVA_HOME in batch file is not working in this case.

One more solution able to control the how many decimal digits to print out based on needs (if you don't want to print redundant zero(s))

For example, if you have a vector as elements and would like to get sum of it

elements <- c(-1e-05, -2e-04, -3e-03, -4e-02, -5e-01, -6e+00, -7e+01, -8e+02)
sum(elements)
## -876.5432

Apparently, the last digital as 1 been truncated, the ideal result should be -876.54321, but if set as fixed printing decimal option, e.g sprintf("%.10f", sum(elements)), redundant zero(s) generate as -876.5432100000

Following the tutorial here: printing decimal numbers, if able to identify how many decimal digits in the certain numeric number, like here in -876.54321, there are 5 decimal digits need to print, then we can set up a parameter for format function as below:

decimal_length <- 5
formatC(sum(elements), format = "f", digits = decimal_length)
## -876.54321

We can change the decimal_length based on each time query, so it can satisfy different decimal printing requirement.

In my case, when using IntelliJ, I had multiple modules in the project. The main module was dependent on another module which had the maven dependencies on Spring.

The main module had Entitys and so did the second module. But when I ran the main module, only the Entitys from the second module got recognized as managed classes.

I then added Spring dependencies on the main module as well, and guess what? It recognized all the Entitys.

There's two ways to say "don't match": character ranges, and zero-width negative lookahead/lookbehind.

The former: don't match a, b, c or 0: [^a-c0]

The latter: match any three-letter string except foo and bar:

(?!foo|bar).{3}

or

.{3}(?<!foo|bar)

Also, a correction for you: *, ? and + do not actually match anything. They are repetition operators, and always follow a matching operator. Thus, a+ means match one or more of a, [a-c0]+ means match one or more of a, b, c or 0, while [^a-c0]+ would match one or more of anything that wasn't a, b, c or 0.

It's possible if you define such a functional interface with multiple type parameters. There is no such built in type. (There are a few limited types with multiple parameters.)

@FunctionalInterface
interface Function6<One, Two, Three, Four, Five, Six> {
    public Six apply(One one, Two two, Three three, Four four, Five five);
}

public static void main(String[] args) throws Exception {
    Function6<String, Integer, Double, Void, List<Float>, Character> func = (a, b, c, d, e) -> 'z';
}

I've called it Function6 here. The name is at your discretion, just try not to clash with existing names in the Java libraries.

There's also no way to define a variable number of type parameters, if that's what you were asking about.

Some languages, like Scala, define a number of built in such types, with 1, 2, 3, 4, 5, 6, etc. type parameters.

Better to use default collapse.js methods (V3 docs, V4 docs):

$('.nav a').click(function(){
    $('.nav-collapse').collapse('hide');
});

Easy way:

str = "[12,23,987,43"

removed = str[1..str.length]

Awesome way:

class String
  def reverse_chop()
    self[1..self.length]
  end
end

"[12,23,987,43".reverse_chop()

(Note: prefer the easy way :) )

At work we have a common library that is used by a few different projects all in a single repository. Originally we used the published (private) version (npm install --save rp-utils) but that lead to a lot of needless version updates as we developed. The library lives in a sister directory to the applications and we are able to use a relative path instead of a version. Instead of "rp-utils": "^1.3.34" in package.json it now is:

{ 
  "dependencies": { ...
    "rp-utils": "../rp-utils",
   ...

the rp-utils directory contains a publishable npm package

char **options[2][100];

declares a size-2 array of size-100 arrays of pointers to pointers to char. You'll want to remove one *. You'll also want to put your string literals in double quotes.

I found this very helpful, check it: http://cdnjs.com/libraries/bootstrap-rtl

Yes: you can sort using a custom comparison function:

std::sort(info.begin(), info.end(), my_custom_comparison);

my_custom_comparison needs to be a function or a class with an operator() overload (a functor) that takes two data objects and returns a bool indicating whether the first is ordered prior to the second (i.e., first < second). Alternatively, you can overload operator< for your class type data; operator< is the default ordering used by std::sort.

Either way, the comparison function must yield a strict weak ordering of the elements.

If on Windows and installed using chocolatey make sure firewall is allowing the default ports for it:

netsh advfirewall firewall add rule name="RabbitMQ Management" dir=in action=allow protocol=TCP localport=15672
netsh advfirewall firewall add rule name="RabbitMQ" dir=in action=allow protocol=TCP localport=5672

for the remote access.

Adding on top of @VonC superb answer, here is a ZSH function that you can add into your .zshrc file:

dockstop() {
  docker rm $(docker stop $(docker ps -a -q --filter ancestor="$1" --format="{{.ID}}"))
}

Then in your command line, simply do dockstop myImageName and it will stop and remove all containers that were started from an image called myImageName.

You need to make the call to setDate separately from the initialization call. So to create the datepicker and set the date in one go:

$("#mydate").datepicker().datepicker("setDate", new Date());

Why it is like this I do not know. If anyone did, that would be interesting information.

I got this working with out removing any patches. The above patch was not working too. Finally what I did was on the IIS server install the following patch and reset / restart the IIS server. This is not for report manager application. This is for any ASP.NET Web application developed in .net3.5 using VS2008 http://www.microsoft.com/downloads/details.aspx?familyid=6AE0AA19-3E6C-474C-9D57-05B2347456B1&displaylang=en

You could add in your code a call system with the new definition:

sprintf(newdef,"export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:%s:%s",ld1,ld2);
system(newdef);

But, I don't know it that is the rigth solution but it works.

The first step in configuring a Windows based development system to connect to an Android device using ADB is to install the appropriate USB drivers on the system. In the case of some devices, the Google USB Driver must be installed (a full listing of devices supported by the Google USB driver can be found online at http://developer.android.com/sdk/win-usb.html).

To install this driver, perform the following steps:

1. Launch Android Studio and open the Android SDK Manager, either by selected Configure -> SDK Manager from the Welcome screen, or using the Tools -> Android -> SDK Manager menu option when working on an existing project.
2. Scroll down to the Extras section and check the status of the Google USB Driver package to make sure that it is listed as Installed.
3. If the driver is not installed, select it and click on the Install packages button to initiate the installation.
4. Once installation is complete, close the Android SDK Manager.

Complete instructions on http://www.techotopia.com/index.php/Testing_Android_Studio_Apps_on_a_Physical_Android_Device (check "Windows ADB Configuration" section).

I basically updated a lot of stuff and then it worked in both Android Studio and Eclipse!

Use div instead of span, or add display: block; to your css style for the span tag.

You can use Bundle to get data :

Bundle extras = intent.getExtras();
String data = extras.getString("data"); // use your key 

And again you can opass this data to next activity :

 Intent intent = new Intent(this, next_Activity.class);
   intent.putExtra("data", data);
   startActivity(intent);

I had the same problem. Following change made it work -

android:layout_width="wrap_content"

The ellipsis, maxLines, or layout_weight - all didn't make any difference. Note - The parent width is also set as wrap_content.

There are a few things you need to bear in mind.

1. There are several ways to submit a form

• using the submit button
• by pressing enter
• by triggering a submit event in JavaScript
• possibly more depending on the device or future device.

We should therefore bind to the form submit event, not the button click event. This will ensure our code works on all devices and assistive technologies now and in the future.

2. Hijax

The user may not have JavaScript enabled. A hijax pattern is good here, where we gently take control of the form using JavaScript, but leave it submittable if JavaScript fails.

We should pull the URL and method from the form, so if the HTML changes, we don't need to update the JavaScript.

3. Unobtrusive JavaScript

Using event.preventDefault() instead of return false is good practice as it allows the event to bubble up. This lets other scripts tie into the event, for example analytics scripts which may be monitoring user interactions.

Speed

We should ideally use an external script, rather than inserting our script inline. We can link to this in the head section of the page using a script tag, or link to it at the bottom of the page for speed. The script should quietly enhance the user experience, not get in the way.

Code

Assuming you agree with all the above, and you want to catch the submit event, and handle it via AJAX (a hijax pattern), you could do something like this:

$(function() {
  $('form.my_form').submit(function(event) {
    event.preventDefault(); // Prevent the form from submitting via the browser
    var form = $(this);
    $.ajax({
      type: form.attr('method'),
      url: form.attr('action'),
      data: form.serialize()
    }).done(function(data) {
      // Optionally alert the user of success here...
    }).fail(function(data) {
      // Optionally alert the user of an error here...
    });
  });
});

You can manually trigger a form submission whenever you like via JavaScript using something like:

$(function() {
  $('form.my_form').trigger('submit');
});

Edit:

I recently had to do this and ended up writing a plugin.

(function($) {
  $.fn.autosubmit = function() {
    this.submit(function(event) {
      event.preventDefault();
      var form = $(this);
      $.ajax({
        type: form.attr('method'),
        url: form.attr('action'),
        data: form.serialize()
      }).done(function(data) {
        // Optionally alert the user of success here...
      }).fail(function(data) {
        // Optionally alert the user of an error here...
      });
    });
    return this;
  }
})(jQuery)

Add a data-autosubmit attribute to your form tag and you can then do this:

HTML

<form action="/blah" method="post" data-autosubmit>
  <!-- Form goes here -->
</form>

JS

$(function() {
  $('form[data-autosubmit]').autosubmit();
});

System.exit() terminates the JVM. Nothing after System.exit() is executed. Return is generally used for exiting a method. If the return type is void, then you could use return; But I don't think is a good practice to do it in the main method. You don't have to do anything for terminate a program, unless infinite loop or some strange other execution flows.

This page tell that using "::" will be faster under certain constraints Just a thing to consider when choosing

Stream is just an abstraction (or a wrapper) over a physical stream of bytes. This physical stream is called the base stream. So there is always a base stream over which a stream wrapper is created and thus the wrapper is named after the base stream type ie FileStream, MemoryStream etc.

The advantage of the stream wrapper is that you get a unified api to interact with streams of any underlying type usb, file etc.

Why would you treat data as stream - because data chunks are loaded on-demand, we can inspect/process the data as chunks rather than loading the entire data into memory. This is how most of the programs deal with big files, for eg encrypting an OS image file.

One more way:

CREATE OR REPLACE TYPE TYPE_TABLE_OF_VARCHAR2 AS TABLE OF VARCHAR(100);
-- ...
SELECT field1, field2, field3
  FROM table1
  WHERE name IN (
    SELECT * FROM table (SELECT CAST(? AS TYPE_TABLE_OF_VARCHAR2) FROM dual)
  );

I don't consider it's optimal, but it works. The hint /*+ CARDINALITY(...) */ would be very useful because Oracle does not understand cardinality of the array passed and can't estimate optimal execution plan.

As another alternative - batch insert into temporary table and using the last in subquery for IN predicate.

In IE I was able to defeat the onfocus=>onblur approach by double-clicking. But remembering the value and then restoring it in the onchange event seems to handle that issue.

<select onfocus="this.oldvalue=this.value;this.blur();" onchange="this.value=this.oldvalue;">
....
</select>

You can do similar without expando properties by using a javascript variable.

If you just want to calculate the schema size without tablespace free space and indexes :

select
   sum(bytes)/1024/1024 as size_in_mega,
   segment_type
from
   dba_segments
where
   owner='<schema's owner>'
group by
   segment_type;

For all schemas

select
   sum(bytes)/1024/1024 as size_in_mega, owner
from
   dba_segments
group by
  owner;

ESLint defaults to ES5 syntax-checking. You'll want to override to the latest well-supported version of JavaScript.

Try adding a .eslintrc file to your project. Inside it:

{
    "parserOptions": {
        "ecmaVersion": 2017
    },

    "env": {
        "es6": true
    }
}

Hopefully this helps.

EDIT: I also found this example .eslintrc which might help.

 {
    if (preg_match('~^http://(?:www\.)?vimeo\.com/(?:clip:)?(\d+)~', $link, $match))

    }

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "http://vimeo.com/api/v2/video/$id.php");
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    $output = unserialize(curl_exec($ch));
    $output = $output[0];
    curl_close($ch);
    return $output;
}`

//at below function pass the thumbnail url.

function save_image_local($thumbnail_url)
    {

         //for save image at local server
         $filename = time().'_hbk.jpg';
         $fullpath = '../../app/webroot/img/videos/image/'.$filename;

         file_put_contents ($fullpath,file_get_contents($thumbnail_url));

        return $filename;
    }

Another way could be to import the module in a function. This way when the function completes the module gets garbage collected.

Generally

Your pkl file is, in fact, a serialized pickle file, which means it has been dumped using Python's pickle module.

To un-pickle the data you can:

import pickle


with open('serialized.pkl', 'rb') as f:
    data = pickle.load(f)

For the MNIST data set

Note gzip is only needed if the file is compressed:

import gzip
import pickle


with gzip.open('mnist.pkl.gz', 'rb') as f:
    train_set, valid_set, test_set = pickle.load(f)

Where each set can be further divided (i.e. for the training set):

train_x, train_y = train_set

Those would be the inputs (digits) and outputs (labels) of your sets.

If you want to display the digits:

import matplotlib.cm as cm
import matplotlib.pyplot as plt


plt.imshow(train_x[0].reshape((28, 28)), cmap=cm.Greys_r)
plt.show()

The other alternative would be to look at the original data:

http://yann.lecun.com/exdb/mnist/

But that will be harder, as you'll need to create a program to read the binary data in those files. So I recommend you to use Python, and load the data with pickle. As you've seen, it's very easy. ;-)

=IIf((CountRows("ScannerStatisticsData")=0),False,True)

Should be replaced with

=IIf((CountRows("ScannerStatisticsData")=0),True,False)

because the Visibility expression set up the Hidden value.

This should work. But I have same problems on an Android phone.

<input type="number" /> <input type="tel" />

I found out, that if I didn't include the jquerymobile-framework, the keypad showed correctly on the two types of fields.

But I havn't found a solution to solve that problem, if you really need to use jquerymobile.

UPDATE: I found out, that if the form-tag is stored out of the

<div data-role="page"> 

The number keypad isn't shown. This must be a bug...

select right('0000' + cast(datepart(year, GETDATE()) as varchar(4)), 4) + '-'+ + right('00' + cast(datepart(month, GETDATE()) as varchar(2)), 2) + '-'+ + right('00' + cast(datepart(day, getdate()) as varchar(2)), 2) as YearMonthDay

Since WP 2.6.0 you can use plugins_url() method.

The answers here were somewhat incomplete. And I had to compile information from other sources to actually acquire the plugin list.

1. Get the Jenkins CLI

The Jenkins CLI will allow us to interact with our Jenkins server from the command line. We can get it with a simple curl call.

curl 'localhost:8080/jnlpJars/jenkins-cli.jar' > jenkins-cli.jar

2. Create a Groovy script for parsing (thanks to malenkiy_scot)

Save the following as plugins.groovy.

def plugins = jenkins.model.Jenkins.instance.getPluginManager().getPlugins()
plugins.each {println "${it.getShortName()}: ${it.getVersion()}"}

3. Call the Jenkins API for plugin results

Call the Jenkins server (localhost:8080 here) with your login username and password while referencing the Groovy script:

java -jar jenkins-cli.jar -s http://localhost:8080 groovy --username "admin" --password "admin" = < plugins.groovy > plugins.txt

The output to plugins.txt looks like this:

ace-editor: 1.1
ant: 1.5
antisamy-markup-formatter: 1.5
authentication-tokens: 1.3
blueocean-autofavorite: 1.0.0
blueocean-commons: 1.1.4
blueocean-config: 1.1.4
blueocean-dashboard: 1.1.4
blueocean-display-url: 2.0
blueocean-events: 1.1.4
blueocean-git-pipeline: 1.1.4
blueocean-github-pipeline: 1.1.4
blueocean-i18n: 1.1.4
blueocean-jwt: 1.1.4
blueocean-personalization: 1.1.4
blueocean-pipeline-api-impl: 1.1.4
blueocean-pipeline-editor: 0.2.0
blueocean-pipeline-scm-api: 1.1.4
blueocean-rest-impl: 1.1.4

Now I return Object. I don't know better solution, but it works.

        entity.put("address", n.getAddress());
        entities.add(entity);
    }
    return new ResponseEntity<Object>(entities, HttpStatus.OK);
}

In Order to obtain real path to the file you can try this:

URL fileUrl = Resourceloader.class.getResource("resources/repository/SSL-Key/cert.jks");
String pathToClass = fileUrl.getPath;    

Resourceloader is classname here. "resources/repository/SSL-Key/cert.jks" is relative path to the file. If you had your guiclass in ./package1/java with rest of folder structure remaining, you would take "../resources/repository/SSL-Key/cert.jks" as relative path because of rules defining relative path.

This way you can read your file with BufferedReader. DO NOT USE THE STRING to identify the path to the file, because if you have spaces or some characters from not english alphabet in your path, you will get problems and the file will not be found.

BufferedReader bufferedReader = new BufferedReader(
                        new InputStreamReader(fileUrl.openStream()));

The env parameter accepts a dictionary. You can simply take os.environ, add a key (your desired variable) (to a copy of the dict if you must) to that and use it as a parameter to Popen.

As precised in the annotation documentation, the annotation indicates that the argument name is used as the property name without any modifications, but it can be specified to non-empty value to specify different name:

I would recommend you to read through the Java tutorial documentation hosted on Oracle's website whenever you are in doubt about anything related to Java.

You can get a clear understanding of the concepts by going through the following tutorials:

• Characters

• Strings

here list attribute name set in request request.setAttribute("List",list); and ArrayList list=new ArrayList();

<%

ArrayList<Category> a=(ArrayList<Category>)request.getAttribute("List");

out.print(a);

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

{
    out.println(a.get(i));

}

Using Pure Vanilla Javascript / Jquery or in any javascript library :

If you have Ckeditor loaded in below text-area:

 <textarea name="editor1" id="editor1"></textarea>

Then you can get content inside textarea as below:

var txtNotes = document.getElementsByClassName('ck-content')[0].innerHTML;

The variable item is a string. An index looks like this:

>>> mystring = 'helloworld'
>>> print mystring[0]
'h'

The above example uses the 0 index of the string to refer to the first character.

Strings can't have string indices (like dictionaries can). So this won't work:

>>> mystring = 'helloworld'
>>> print mystring['stringindex']
TypeError: string indices must be integers

Mysqli makes use of object oriented programming. Try using this approach instead:

function dbCon() {
        if($mysqli = new mysqli('$hostname','$username','$password','$databasename')) return $mysqli; else return false;
}

if(!dbCon())
exit("<script language='javascript'>alert('Unable to connect to database')</script>");
else $con=dbCon();

if (isset($_GET['part'])){
    $partid = $_GET['part'];
    $sql = "SELECT * 
        FROM $usertable 
        WHERE PartNumber = $partid";

    $result=$con->query($sql_query);
    $row = $result->fetch_assoc();

    $partnumber = $partid;
    $nsn = $row["NSN"];
    $description = $row["Description"];
    $quantity = $row["Quantity"];
    $condition = $row["Conditio"];
}

Let me know if you have any questions, I could not test this code so you might need to tripple check it!

Have you tried using Html.fromHtml(source)?

I think that class is pretty liberal with respect to source quality (it uses TagSoup internally, which was designed with real-life, bad HTML in mind). It doesn't support all HTML tags though, but it does come with a handler you can implement to react on tags it doesn't understand.

@Html.TextArea("txtNotes", "", 4, 0, new { @class = "k-textbox", style = "width: 100%; height: 100%;" })

To show a grid line on every tick, add

plt.grid(True)

For example:

import matplotlib.pyplot as plt

points = [
    (0, 10),
    (10, 20),
    (20, 40),
    (60, 100),
]

x = list(map(lambda x: x[0], points))
y = list(map(lambda x: x[1], points))

plt.scatter(x, y)
plt.grid(True)

plt.show()

In addition, you might want to customize the styling (e.g. solid line instead of dashed line), add:

plt.rc('grid', linestyle="-", color='black')

For example:

import matplotlib.pyplot as plt

points = [
    (0, 10),
    (10, 20),
    (20, 40),
    (60, 100),
]

x = list(map(lambda x: x[0], points))
y = list(map(lambda x: x[1], points))

plt.rc('grid', linestyle="-", color='black')
plt.scatter(x, y)
plt.grid(True)

plt.show()

For Most of my programs the scripts in this Post did the job. But I had to face a legacy program that I couldn't remove using msiexec.exe or Win32_Product class. (from some reason I got exit 0 but the program was still there)

My solution was to use Win32_Process class:

with the help from nickdnk this command is to get the uninstall exe file path:

64bit:

[array]$unInstallPathReg= gci "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" | foreach { gp $_.PSPath } | ? { $_ -match $programName } | select UninstallString

32bit:

 [array]$unInstallPathReg= gci "HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall" | foreach { gp $_.PSPath } | ? { $_ -match $programName } | select UninstallString

you will have to clean the the result string:

$uninstallPath = $unInstallPathReg[0].UninstallString
$uninstallPath = $uninstallPath -Replace "msiexec.exe","" -Replace "/I","" -Replace "/X",""
$uninstallPath = $uninstallPath .Trim()

now when you have the relevant program uninstall exe file path you can use this command:

$uninstallResult = (Get-WMIObject -List -Verbose | Where-Object {$_.Name -eq "Win32_Process"}).InvokeMethod("Create","$unInstallPath")

$uninstallResult - will have the exit code. 0 is success

the above commands can also run remotely - I did it using invoke command but I believe that adding the argument -computername can work

It can also be caused by piping out of a pair of curly braces on a line.

This fails:

{ /usr/local/bin/mycommand ; outputstatus=$? } >> /var/log/mycommand.log 2>&1h
do_something
#Get NOW that saved output status for the following $? invocation
sh -c "exit $outputstatus"
do_something_more

while this is allowed:

{
   /usr/local/bin/mycommand
   outputstatus=$?
} >> /var/log/mycommand.log 2>&1h
do_something
#Get NOW that saved output status for the following $? invocation
sh -c "exit $outputstatus"
do_something_more

An anonymous class usually implements an interface:

new Runnable() { // implements Runnable!
   public void run() {}
}

JFrame.addWindowListener( new WindowAdapter() { // extends  class
} );

If you mean whether you can implement 2 or more interfaces, than I think that's not possible. You can then make a private interface which combines the two. Though I cannot easily imagine why you would want an anonymous class to have that:

 public class MyClass {
   private interface MyInterface extends Runnable, WindowListener { 
   }

   Runnable r = new MyInterface() {
    // your anonymous class which implements 2 interaces
   }

 }

if you're on windows:

http://windows.github.com/

otherwise: http://git-scm.com/downloads/guis

Working for me on IE:

<script type="text/javascript">
  var WinNetwork = new ActiveXObject("WScript.Network");
  document.write(WinNetwork.UserName);
</script>

...but ActiveX controls needs to be on in security settings.

Using pure Javascript:

Don't need to pass this to the SomeDeleteRowFunction():

<td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction()"></td>

The onclick function:

function SomeDeleteRowFunction() {
      // event.target will be the input element.
      var td = event.target.parentNode; 
      var tr = td.parentNode; // the row to be removed
      tr.parentNode.removeChild(tr);
}

This is expected behavior for an uncaught exception with display_errors off.

Your options here are to turn on display_errors via php or in the ini file or catch and output the exception.

 ini_set("display_errors", 1);

or

 try{
     // code that may throw an exception
 } catch(Exception $e){
     echo $e->getMessage();
 }

If you are throwing exceptions, the intention is that somewhere further down the line something will catch and deal with it. If not it is a server error (500).

Another option for you would be to use set_exception_handler to set a default error handler for your script.

 function default_exception_handler(Exception $e){
          // show something to the user letting them know we fell down
          echo "<h2>Something Bad Happened</h2>";
          echo "<p>We fill find the person responsible and have them shot</p>";
          // do some logging for the exception and call the kill_programmer function.
 }
 set_exception_handler("default_exception_handler");

Here's an alternative:

<svg ...>
  <switch>
    <g requiredFeatures="http://www.w3.org/Graphics/SVG/feature/1.2/#TextFlow">
      <textArea width="200" height="auto">
       Text goes here
      </textArea>
    </g>
    <foreignObject width="200" height="200" 
     requiredFeatures="http://www.w3.org/TR/SVG11/feature#Extensibility">
      <p xmlns="http://www.w3.org/1999/xhtml">Text goes here</p>
    </foreignObject>
    <text x="20" y="20">No automatic linewrapping.</text>
  </switch>
</svg>

Noting that even though foreignObject may be reported as being supported with that featurestring, there's no guarantee that HTML can be displayed because that's not required by the SVG 1.1 specification. There is no featurestring for html-in-foreignobject support at the moment. However, it is still supported in many browsers, so it's likely to become required in the future, perhaps with a corresponding featurestring.

Note that the 'textArea' element in SVG Tiny 1.2 supports all the standard svg features, e.g advanced filling etc, and that you can specify either of width or height as auto, meaning that the text can flow freely in that direction. ForeignObject acts as clipping viewport.

Note: while the above example is valid SVG 1.1 content, in SVG 2 the 'requiredFeatures' attribute has been removed, which means the 'switch' element will try to render the first 'g' element regardless of having support for SVG 1.2 'textArea' elements. See SVG2 switch element spec.

I agree with using frameworks for things like this, just because its easier. I hacked this up real quick, just fades an image out and then switches, also will not work in older versions of IE. But as you can see the code for the actual fade is much longer than the JQuery implementation posted by KARASZI István.

function changeImage() {
    var img = document.getElementById("img");
    img.src = images[x];
    x++;        
    if(x >= images.length) {
        x = 0;
    } 
    fadeImg(img, 100, true);
    setTimeout("changeImage()", 30000);
}

function fadeImg(el, val, fade) {
    if(fade === true) {
        val--;
    } else {
        val ++;
    }       
    if(val > 0 && val < 100) {
        el.style.opacity = val / 100;
        setTimeout(function(){ fadeImg(el, val, fade); }, 10);
    }
}

var images = [], x = 0;
images[0] = "image1.jpg";
images[1] = "image2.jpg";
images[2] = "image3.jpg";
setTimeout("changeImage()", 30000);

Use $ne instead of $not

http://docs.mongodb.org/manual/reference/operator/ne/#op._S_ne

db.collections.find({"name": {$ne: ""}});

The best way to retrieve your public folder path from your Laravel config is the function:

$myPublicFolder = public_path();
$savePath = $mypublicPath."enter_path_to_save";
$path = $savePath."filename.ext";
return File::put($path , $data);

There is no need to have all the variables, but this is just for a demonstrative purpose.

Hope this helps, GRnGC

An extra method that doesn't rely on which shell/bash version you have is by using envsubst. For example:

newvar=$(echo '$magic_variable_'"${dynamic_part}" | envsubst)

No, not broken, but most decimal fractions must be approximated

Summary

Floating point arithmetic is exact, unfortunately, it doesn't match up well with our usual base-10 number representation, so it turns out we are often giving it input that is slightly off from what we wrote.

Even simple numbers like 0.01, 0.02, 0.03, 0.04 ... 0.24 are not representable exactly as binary fractions. If you count up 0.01, .02, .03 ..., not until you get to 0.25 will you get the first fraction representable in base₂. If you tried that using FP, your 0.01 would have been slightly off, so the only way to add 25 of them up to a nice exact 0.25 would have required a long chain of causality involving guard bits and rounding. It's hard to predict so we throw up our hands and say "FP is inexact", but that's not really true.

We constantly give the FP hardware something that seems simple in base 10 but is a repeating fraction in base 2.

How did this happen?

When we write in decimal, every fraction (specifically, every terminating decimal) is a rational number of the form

           a / (2ⁿ x 5^m)

In binary, we only get the 2ⁿ term, that is:

           a / 2ⁿ

So in decimal, we can't represent ¹/₃. Because base 10 includes 2 as a prime factor, every number we can write as a binary fraction also can be written as a base 10 fraction. However, hardly anything we write as a base₁₀ fraction is representable in binary. In the range from 0.01, 0.02, 0.03 ... 0.99, only three numbers can be represented in our FP format: 0.25, 0.50, and 0.75, because they are 1/4, 1/2, and 3/4, all numbers with a prime factor using only the 2ⁿ term.

In base₁₀ we can't represent ¹/₃. But in binary, we can't do ¹/₁₀ or ¹/₃.

So while every binary fraction can be written in decimal, the reverse is not true. And in fact most decimal fractions repeat in binary.

Dealing with it

Developers are usually instructed to do < epsilon comparisons, better advice might be to round to integral values (in the C library: round() and roundf(), i.e., stay in the FP format) and then compare. Rounding to a specific decimal fraction length solves most problems with output.

Also, on real number-crunching problems (the problems that FP was invented for on early, frightfully expensive computers) the physical constants of the universe and all other measurements are only known to a relatively small number of significant figures, so the entire problem space was "inexact" anyway. FP "accuracy" isn't a problem in this kind of application.

The whole issue really arises when people try to use FP for bean counting. It does work for that, but only if you stick to integral values, which kind of defeats the point of using it. This is why we have all those decimal fraction software libraries.

I love the Pizza answer by Chris, because it describes the actual problem, not just the usual handwaving about "inaccuracy". If FP were simply "inaccurate", we could fix that and would have done it decades ago. The reason we haven't is because the FP format is compact and fast and it's the best way to crunch a lot of numbers. Also, it's a legacy from the space age and arms race and early attempts to solve big problems with very slow computers using small memory systems. (Sometimes, individual magnetic cores for 1-bit storage, but that's another story.)

Conclusion

If you are just counting beans at a bank, software solutions that use decimal string representations in the first place work perfectly well. But you can't do quantum chromodynamics or aerodynamics that way.

try:

.table-hover > tbody > tr.active:hover > th {
                background-color: #color;
            }

You can use this code

var stringDate = "2005-07-08T00:00:00+0000";
var dTimezone = new Date();
var offset = dTimezone.getTimezoneOffset() / 60;
var date = new Date(Date.parse(stringDate));
date.setHours(date.getHours() + offset);

"Allocation Failure" is cause of GC to kick is not correct. It is an outcome of GC operation.

GC kicks in when there is no space to allocate( depending on region minor or major GC is performed). Once GC is performed if space is freed good enough, but if there is not enough size it fails. Allocation Failure is one such failure. Below document have good explanation https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/g1_gc.html

private void btnDelete_Click(object sender, EventArgs e)
{
    if (e.ColumIndex == 10)// 10th column the button
    {
        dataGridView1.Rows.Remove(dataGridView1.Rows[e.RowIndex]);
    }                
}

This solution can be delete a row (not selected, clicked row!) via "e" param.

Apart from above information, there is still an interesting history of LF (\n) and CR (\r). [Original author : ??? Source : http://www.ruanyifeng.com/blog/2006/04/post_213.html] Before computer came out, there was a type of teleprinter called Teletype Model 33. It can print 10 characters each second. But there is one problem with this, after finishing printing each line, it will take 0.2 second to move to next line, which is time of printing 2 characters. If a new characters is transferred during this 0.2 second, then this new character will be lost.

So scientists found a way to solve this problem, they add two ending characters after each line, one is 'Carriage return', which is to tell the printer to bring the print head to the left.; the other one is 'Line feed', it tells the printer to move the paper up 1 line.

Later, computer became popular, these two concepts are used on computers. At that time, the storage device was very expensive, so some scientists said that it was expensive to add two characters at the end of each line, one is enough, so there are some arguments about which one to use.

In UNIX/Mac and Linux, '\n' is put at the end of each line, in Windows, '\r\n' is put at the end of each line. The consequence of this use is that files in UNIX/Mac will be displayed in one line if opened in Windows. While file in Windows will have one ^M at the end of each line if opened in UNIX or Mac.

Just use square brackets instead:

print arr[1,1]

This works with font awesome:

<button class="btn btn-outline-success">
   <i class="fa fa-print" aria-hidden="true"></i>
   Print
</button>

How to call method:

centerInParent - false

addOrRemoveProperty(mView, RelativeLayout.CENTER_IN_PARENT, false);

centerHorizontal - true

addOrRemoveProperty(mView, RelativeLayout.CENTER_HORIZONTAL, true);

centerHorizontal - false

addOrRemoveProperty(mView, RelativeLayout.CENTER_HORIZONTAL, false);

centerVertical - true

addOrRemoveProperty(mView, RelativeLayout.CENTER_VERTICAL, true);

centerVertical - false

addOrRemoveProperty(mView, RelativeLayout.CENTER_VERTICAL, false);

Hope this would help you.

A tip: you can use below code if your value is dynamic:

$("#list option[value='"+aDynamicValue+"']").text();

Or (better style)

$("#list option").filter(function() {
     return this.value === aDynamicValue;
}).text();

As mentioned in jQuery get specific option tag text and placing dynamic variable to the value

hashMap.keySet().toArray(); // returns an array of keys
hashMap.values().toArray(); // returns an array of values

Edit

It should be noted that the ordering of both arrays may not be the same, See oxbow_lakes answer for a better approach for iteration when the pair key/values are needed.

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

Instead of using sed to filter out the certificate, you can also pipe the openssl s_client output through openssl x509 -out certfile.txt, for example:

echo "" | openssl s_client -connect my.server.com:443 -showcerts 2>/dev/null | openssl x509 -out certfile.txt

Unlike in Python 2, the zip function in Python 3 returns an iterator. Iterators can only be exhausted (by something like making a list out of them) once. The purpose of this is to save memory by only generating the elements of the iterator as you need them, rather than putting it all into memory at once. If you want to reuse your zipped object, just create a list out of it as you do in your second example, and then duplicate the list by something like

 test2 = list(zip(lis1,lis2))
 zipped_list = test2[:]
 zipped_list_2 = list(test2)

You need to clear the OnCheckedChangeListener before setting setChecked():

@Override
public void onBindViewHolder(final ViewHolder holder, int position) {

    holder.mRadioButton.setOnCheckedChangeListener(null);
    holder.mRadioButton.setChecked(position == mCheckedPosition);
    holder.mRadioButton.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

            mCheckedPosition = position;
            notifyDataSetChanged();
        }
    });
}

This way it won't trigger the java.lang.IllegalStateException: Cannot call this method while RecyclerView is computing a layout or scrolling error.

cmd /c "command" syntax works well. Also, if you want to include an executable that contains a space in the path, you will need two sets of quotes.

cmd /c ""path to executable""

and if your executable needs a file input with a space in the path a another set

cmd /c ""path to executable" -f "path to file"" 

The left hand side of the = operator needs to be a variable. What you're doing here is telling python: "You know the number one? Set it to the inputted string.". 1 is a literal number, not a variable. 1 is always 1, you can't "set" it to something else.

A variable is like a box in which you can store a value. 1 is a value that can be stored in the variable. The input call returns a string, another value that can be stored in a variable.

Instead, use lists:

import random

namelist = []
namelist.append(input("Please enter name 1:"))  #Stored in namelist[0]
namelist.append(input('Please enter name 2:'))  #Stored in namelist[1]
namelist.append(input('Please enter name 3:'))  #Stored in namelist[2]
namelist.append(input('Please enter name 4:'))  #Stored in namelist[3]
namelist.append(input('Please enter name 5:'))  #Stored in namelist[4]

nameindex = random.randint(0, 5)
print('Well done {}. You are the winner!'.format(namelist[nameindex]))

Using a for loop, you can cut down even more:

import random

namecount = 5
namelist=[]
for i in range(0, namecount):
  namelist.append(input("Please enter name %s:" % (i+1))) #Stored in namelist[i]

nameindex = random.randint(0, namecount)
print('Well done {}. You are the winner!'.format(namelist[nameindex]))

Command find_package has two modes: Module mode and Config mode. You are trying to use Module mode when you actually need Config mode.

Module mode

Find<package>.cmake file located within your project. Something like this:

CMakeLists.txt
cmake/FindFoo.cmake
cmake/FindBoo.cmake

CMakeLists.txt content:

list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/cmake")
find_package(Foo REQUIRED) # FOO_INCLUDE_DIR, FOO_LIBRARIES
find_package(Boo REQUIRED) # BOO_INCLUDE_DIR, BOO_LIBRARIES

include_directories("${FOO_INCLUDE_DIR}")
include_directories("${BOO_INCLUDE_DIR}")
add_executable(Bar Bar.hpp Bar.cpp)
target_link_libraries(Bar ${FOO_LIBRARIES} ${BOO_LIBRARIES})

Note that CMAKE_MODULE_PATH has high priority and may be usefull when you need to rewrite standard Find<package>.cmake file.

Config mode (install)

<package>Config.cmake file located outside and produced by install command of other project (Foo for example).

foo library:

> cat CMakeLists.txt 
cmake_minimum_required(VERSION 2.8)
project(Foo)

add_library(foo Foo.hpp Foo.cpp)
install(FILES Foo.hpp DESTINATION include)
install(TARGETS foo DESTINATION lib)
install(FILES FooConfig.cmake DESTINATION lib/cmake/Foo)

Simplified version of config file:

> cat FooConfig.cmake 
add_library(foo STATIC IMPORTED)
find_library(FOO_LIBRARY_PATH foo HINTS "${CMAKE_CURRENT_LIST_DIR}/../../")
set_target_properties(foo PROPERTIES IMPORTED_LOCATION "${FOO_LIBRARY_PATH}")

By default project installed in CMAKE_INSTALL_PREFIX directory:

> cmake -H. -B_builds
> cmake --build _builds --target install
-- Install configuration: ""
-- Installing: /usr/local/include/Foo.hpp
-- Installing: /usr/local/lib/libfoo.a
-- Installing: /usr/local/lib/cmake/Foo/FooConfig.cmake

Config mode (use)

Use find_package(... CONFIG) to include FooConfig.cmake with imported target foo:

> cat CMakeLists.txt 
cmake_minimum_required(VERSION 2.8)
project(Boo)

# import library target `foo`
find_package(Foo CONFIG REQUIRED)

add_executable(boo Boo.cpp Boo.hpp)
target_link_libraries(boo foo)
> cmake -H. -B_builds -DCMAKE_VERBOSE_MAKEFILE=ON
> cmake --build _builds
Linking CXX executable Boo
/usr/bin/c++ ... -o Boo /usr/local/lib/libfoo.a

Note that imported target is highly configurable. See my answer.

Update

• Example

It is crucial to know that attributes are not parameters.

The return type for attributes is an Object, whereas the return type for a parameter is a String. When calling the getAttribute(String name) method, bear in mind that the attributes must be cast.

Additionally, there is no servlet specific attributes, and there are no session parameters.

This post is written with the purpose to connect on @Bozho's response, as additional information that can be useful for other people.

Here's a solution that shuffles a list of unique numbers (no repeats, ever).

for (var a=[],i=0;i<40;++i) a[i]=i;

// http://stackoverflow.com/questions/962802#962890
function shuffle(array) {
  var tmp, current, top = array.length;
  if(top) while(--top) {
    current = Math.floor(Math.random() * (top + 1));
    tmp = array[current];
    array[current] = array[top];
    array[top] = tmp;
  }
  return array;
}

a = shuffle(a);

If you want to allow repeated values (which is not what the OP wanted) then look elsewhere. :)

• Open the PDF in MacOS´ Preview App
• Chose File menu –> Export as PDF
• In the export dialog klick the Details button an select your page size
• Click save

All pages of the resulting document will be scaled to that size. The resulting file size is nearly identical to the original PDF, so I conclude, that image resolutions/compressions are not changed.

Hints:

1. I am not sure whether the "Export as PDF" menu item is available by default or only if Adobe Acrobat is installed.

2. My first trial was to use Preview App and print (!) into a new PDF, but this leads to additional margins around the page content.

Short and Sweet code.

try {       
    Class.forName("com.mysql.jdbc.Driver");
    System.out.println("Driver Loaded");
    conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/testDB","root","");
    //Database Name - testDB, Username - "root", Password - ""
    System.out.println("Connected...");         
} catch(Exception e) {
    e.printStackTrace();
}

For SQL server 2012

try {
    String url = "jdbc:sqlserver://KHILAN:1433;databaseName=testDB;user=Khilan;password=Tuxedo123"; 
    //KHILAN is Host    and 1433 is port number     
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    System.out.println("Driver Loaded");
    conn = DriverManager.getConnection(url);
    System.out.println("Connected...");
} catch(Exception e) {
    e.printStackTrace();
}

Okay, I'm going to completely ignore the ridiculous amount of over engineering and assumptions that the other answers are rife with, and go with the simple option.

If you're okay for there to be a single database call during each request, then the method is simple, alarmingly so:

class BaseController extends \Controller
{

    protected $site_settings;

    public function __construct() 
    {
        // Fetch the Site Settings object
        $this->site_settings = Setting::all();
        View::share('site_settings', $this->site_settings);
    }

}

Now providing that all of your controllers extend this BaseController, they can just do $this->site_settings.

If you wish to limit the amount of queries across multiple requests, you could use a caching solution as previously provided, but based on your question, the simple answer is a class property.

There's no need for you to use super-call of the ActionBarDrawerToggle which requires the Toolbar. This means instead of using the following constructor:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, Toolbar toolbar, int openDrawerContentDescRes, int closeDrawerContentDescRes)

You should use this one:

ActionBarDrawerToggle(Activity activity, DrawerLayout drawerLayout, int openDrawerContentDescRes, int closeDrawerContentDescRes)

So basically the only thing you have to do is to remove your custom drawable:

super(mActivity, mDrawerLayout, R.string.ns_menu_open, R.string.ns_menu_close);

More about the "new" ActionBarDrawerToggle in the Docs (click).

Easy. text = text.remove(text.length - 3). I subtracted 3 because the Remove function removes all items from that index to the end of the string which is text.length. So if I subtract 3 then I get the string with 3 characters removed from it.

You can generalize this to removing a characters from the end of the string, like this:

text = text.remove(text.length - a) 

So what I did was the same logic. The remove function removes all items from its inside to the end of the string which is the length of the text. So if I subtract a from the length of the string that will give me the string with a characters removed.

So it doesn't just work for 3, it works for all positive integers, except if the length of the string is less than or equal to a, in that case it will return a negative number or 0.

You can have multiple router-outlet in same template by configuring your router and providing name to your router-outlet, you can achieve this as follows.

Advantage of below approach is thats you can avoid dirty looking URL with it. eg: /home(aux:login) etc.

Assuming on load you are bootstraping appComponent.

app.component.html

<div class="layout">
    <div class="page-header">
        //first outlet to load required component
        <router-outlet name='child1'></router-outlet>
    </div>
    <div class="content">
        //second outlet to load required component
        <router-outlet name='child2'></router-outlet>
    </div>
</div>

Add following to your router.

{
    path: 'home',  // you can keep it empty if you do not want /home
    component: 'appComponent',
    children: [
        {
            path: '',
            component: childOneComponent,
            outlet: 'child1'
        },
        {
            path: '',
            component: childTwoComponent,
            outlet: 'child2'
        }
    ]
}

Now when /home is loaded appComponent will get load with allocated template, then angular router will check the route and load the children component in specified router outlet on the basis of name.

Like above you can configure your router to have multiple router-outlet in same route.

Is Java installed on your computer? Is the path to its bin directory set properly (in other words if you type 'java' from the command line do you get back a list of instructions or do you get something like "java is not recognized as a .....")?

You could try try running squirrel-sql.jar from the command line (from the squirrel sql directory), using:

java -jar squirrel-sql.jar

Image can not be shown until it serves from any server. so you need to upload the image to your server to show its preview.

The reason for this error is that in Python 3, strings are Unicode, but when transmitting on the network, the data needs to be bytes instead. So... a couple of suggestions:

1. Suggest using c.sendall() instead of c.send() to prevent possible issues where you may not have sent the entire msg with one call (see docs).
2. For literals, add a 'b' for bytes string: c.sendall(b'Thank you for connecting')
3. For variables, you need to encode Unicode strings to byte strings (see below)

Best solution (should work w/both 2.x & 3.x):

output = 'Thank you for connecting'
c.sendall(output.encode('utf-8'))

Epilogue/background: this isn't an issue in Python 2 because strings are bytes strings already -- your OP code would work perfectly in that environment. Unicode strings were added to Python in releases 1.6 & 2.0 but took a back seat until 3.0 when they became the default string type. Also see this similar question as well as this one.

To search in all sub-directories, but only in specific file types, use grep with --include.

For example, searching recursively in current directory, for text in *.yml and *.yaml :

grep "text to search" -r . --include=*.{yml,yaml}

Invalidate Cache / Restart from File option.

Just unchecking offline mode did not work for me.

If you're on windows, you need to install the drivers for your phone. You can get them here.

If it still doesn't work, I've had luck connecting by manually restarting the Android Debug Bridge manually. More info is here.

I'm not sure exactly what you want, but I think it's along the lines of:

SELECT `Item`, `qty`-`BAL_QTY` as `qty` FROM ((SELECT Item, SUM(`QTY`) as qty FROM `master_table` GROUP BY `ITEM`) as A NATURAL JOIN `stock_table`) as B

Let PowerShell analyze and decide the data type. It internally uses a 'Variant' for this.

And generally it does a good job...

param($x)
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
    $iTunes.PlayerPosition = $iTunes.PlayerPosition + $x
}

Or if you need to pass multiple parameters:

param($x1, $x2)
$iTunes = New-Object -ComObject iTunes.Application
if ($iTunes.playerstate -eq 1)
{
    $iTunes.PlayerPosition = $iTunes.PlayerPosition + $x1
    $iTunes.<AnyProperty>  = $x2
}

On your .m file, you can declare a variable as static:

static ClassName *variableName = nil;

Then you can initialize it on your +(void)initialize method.

Please note that this is a plain C static variable and is not static in the sense Java or C# consider it, but will yield similar results.

Using Kotlin:

You can set the flag directly using setter method. In Kotlin or is the replacement for the Java bitwise or |.

intent.flags = FLAG_ACTIVITY_NEW_TASK or FLAG_ACTIVITY_CLEAR_TASK

If you plan to use this regularly, create an Intent extension function

fun Intent.clearStack() {
    flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
}

You can then directly call this function before starting the intent

intent.clearStack()

At the moment, this can be done as follows

$ANDROID_HOME/build-tools/28.0.3/aapt dump badging /<path to>/<app name>.apk

You first have to tell Gnuplot to use a style that uses points, e.g. with points or with linespoints. Try for example:

plot sin(x) with points

Output:

Now try:

Output:

You may also want to look at the output from the test command which shows you the capabilities of the current terminal. Here are the capabilities for my pngairo terminal:

ORDER BY column1 DESC, column2

This sorts everything by column1 (descending) first, and then by column2 (ascending, which is the default) whenever the column1 fields for two or more rows are equal.

Slightly quicker than removing each one individually:

$('#myTable').empty()

Technically, this will remove thead, tfoot and tbody elements too.

You can check if string contains numbers only:

Regex.IsMatch(myStringVariable, @"^-?\d+$")

But number can be bigger than Int32.MaxValue or less than Int32.MinValue - you should keep that in mind.

Another option - create extension method and move ugly code there:

public static bool IsInteger(this string s)
{
   if (String.IsNullOrEmpty(s))
       return false;

   int i;
   return Int32.TryParse(s, out i);
}

That will make your code more clean:

if (myStringVariable.IsInteger())
    // ...

#!/bin/sh

#Find the Process ID for syncapp running instance

PID=`ps -ef | grep syncapp 'awk {print $2}'`

if [[ -z "$PID" ]] then

Not sure if this helps, but 'kill' is not spelled correctly. It's capitalized.

Try 'kill' instead.

there are many causes such as

• The network link between server and client may be temporarily going down.
• running out of system resources.
• sending malformed data.

To examine the problem in detail, you can use Wireshark.

Short answer (valid as of 2015-04-16): removeAtIndex(myString.endIndex.predecessor())

Example:

var howToBeHappy = "Practice compassion, attention and gratitude. And smile!!"
howToBeHappy.removeAtIndex(howToBeHappy.endIndex.predecessor())
println(howToBeHappy)
// "Practice compassion, attention and gratitude. And smile!"

The language continues its rapid evolution, making the half-life for many formerly-good S.O. answers dangerously brief. It's always best to learn the language and refer to real documentation.

Jason Robinson's answer and Sami Eltamawy answer are excelent.

Just an improvement to complete the aproach, you should use compat ExifInterface.

com.android.support:exifinterface:${lastLibVersion}

You will be able to instantiate the ExifInterface(pior API <24) with InputStream (from ContentResolver) instead of uri paths avoiding "File not found exceptions"

https://android-developers.googleblog.com/2016/12/introducing-the-exifinterface-support-library.html

You can make a template function, and pass the array by reference to achieve this.

Here is my code snippet

template <typename TypeOfData>


void PrintArray(TypeOfData &arrayOfType);

int main()

{

    char charArray[] = "my name is";

    int intArray[] = { 1,2,3,4,5,6 };

    double doubleArray[] = { 1.1,2.2,3.3 };


    PrintArray(charArray);

    PrintArray(intArray);

    PrintArray(doubleArray);

}


template <typename TypeOfData>

void PrintArray(TypeOfData &arrayOfType)

{

    int elementsCount = sizeof(arrayOfType) / sizeof(arrayOfType[0]);


    for (int i = 0; i < elementsCount; i++)

    {

        cout << "Value in elements at position " << i + 1 << " is " << arrayOfType[i] << endl;

    }

}

Delete the .sdf file that is in your solution directory. It's just the Intellisense database, and Visual Studio will recreate it the next time you open that solution. This db can get corrupted and cause the IDE to not be able to find things, and since the compiler generates this information for itself on the fly, it wouldn't be affected.

In PHP there is a global variable containing various details related to the server. It's called $_SERVER. It contains also the root:

 $_SERVER['DOCUMENT_ROOT']

The only problem is that the entries in this variable are provided by the web server and there is no guarantee that all web servers offer them.

Yes, the SSL connection is between the TCP layer and the HTTP layer. The client and server first establish a secure encrypted TCP connection (via the SSL/TLS protocol) and then the client will send the HTTP request (GET, POST, DELETE...) over that encrypted TCP connection.

I used this method

div.image-thumbnail
{
    width: 85px;
    height: 85px;
    line-height: 85px;
    display: inline-block;
    text-align: center;
}
div.image-thumbnail img
{
    vertical-align: middle;
}

Clear your old viewmodel and set the new data to the adapter and call notifyDataSetChanged()

var reverseString = function(str){ 
  let length = str.length - 1;
  str = str.split('');

  for(let i=0;i<= length;i++){
    str[length + i + 1] = str[length - i];
  }

  return str.splice(length + 1).join('');
}

string = string.replace(/[\W_]/g, "_");

Another solution is convert difference to a new Date object and get that date's year(diff from 1970), month, day etc.

var date1 = new Date(2010, 6, 17);
var date2 = new Date(2013, 12, 18);
var diff = new Date(date2.getTime() - date1.getTime());
// diff is: Thu Jul 05 1973 04:00:00 GMT+0300 (EEST)

console.log(diff.getUTCFullYear() - 1970); // Gives difference as year
// 3

console.log(diff.getUTCMonth()); // Gives month count of difference
// 6

console.log(diff.getUTCDate() - 1); // Gives day count of difference
// 4

So difference is like "3 years and 6 months and 4 days". If you want to take difference in a human readable style, that can help you.

The loc parameter specifies in which corner of the bounding box the legend is placed. The default for loc is loc="best" which gives unpredictable results when the bbox_to_anchor argument is used.
Therefore, when specifying bbox_to_anchor, always specify loc as well.

The default for bbox_to_anchor is (0,0,1,1), which is a bounding box over the complete axes. If a different bounding box is specified, is is usually sufficient to use the first two values, which give (x0, y0) of the bounding box.

Below is an example where the bounding box is set to position (0.6,0.5) (green dot) and different loc parameters are tested. Because the legend extents outside the bounding box, the loc parameter may be interpreted as "which corner of the legend shall be placed at position given by the 2-tuple bbox_to_anchor argument".

import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = 6, 3
fig, axes = plt.subplots(ncols=3)
locs = ["upper left", "lower left", "center right"]
for l, ax in zip(locs, axes.flatten()):
    ax.set_title(l)
    ax.plot([1,2,3],[2,3,1], "b-", label="blue")
    ax.plot([1,2,3],[1,2,1], "r-", label="red")
    ax.legend(loc=l, bbox_to_anchor=(0.6,0.5))
    ax.scatter((0.6),(0.5), s=81, c="limegreen", transform=ax.transAxes)

plt.tight_layout()    
plt.show()

See especially this answer for a detailed explanation and the question What does a 4-element tuple argument for 'bbox_to_anchor' mean in matplotlib? .

ax.legend(bbox_to_anchor=(1,0), loc="lower right",  bbox_transform=fig.transFigure)

It may not make too much sense to use data coordinates, but since you asked for it this would be done via bbox_transform=ax.transData.

I use the DataGridView's Invalidate() function. However, that will refresh the entire DataGridView. If you want to refresh a particular row, you use dgv.InvalidateRow(rowIndex). If you want to refresh a particular cell, you can use dgv.InvalidateCell(columnIndex, rowIndex). This is of course assuming you're using a binding source or data source.

When using propedit make sure not have any trailing spaces as that will cause the file to be excluded from the ignore list.

Shortest way to get all dictionary/object values:

From Java 8 and onward we don't have to use Collections.sort() directly. List interface has a default sort() method:

List<User> users = Arrays.asList(user1,user2,user3);
users.sort( (u1, u2) -> { 
return u1.getFirstName.compareTo(u2.getFirstName());});

Naive Bayes: Naive Bayes comes under supervising machine learning which used to make classifications of data sets. It is used to predict things based on its prior knowledge and independence assumptions.

They call it naive because it’s assumptions (it assumes that all of the features in the dataset are equally important and independent) are really optimistic and rarely true in most real-world applications.

It is classification algorithm which makes the decision for the unknown data set. It is based on Bayes Theorem which describe the probability of an event based on its prior knowledge.

Below diagram shows how naive Bayes works

Formula to predict NB:

How to use Naive Bayes Algorithm ?

Let's take an example of how N.B woks

Step 1: First we find out Likelihood of table which shows the probability of yes or no in below diagram. Step 2: Find the posterior probability of each class.

Problem: Find out the possibility of whether the player plays in Rainy condition?

P(Yes|Rainy) = P(Rainy|Yes) * P(Yes) / P(Rainy)

P(Rainy|Yes) = 2/9 = 0.222
P(Yes) = 9/14 = 0.64
P(Rainy) = 5/14 = 0.36

Now, P(Yes|Rainy) = 0.222*0.64/0.36 = 0.39 which is lower probability which means chances of the match played is low.

I have the same problem and try almost all these suggestions and another options but nothing works for my case.

So I had run verbose command: (mvn install -X) and saw the problem with Jacoco lib, and finally found this answer that works for me.

Change the Jacoco lib version in my pom file.

Java file : Jclass.java

package Jclasspackage

public class Jclass {

    public String uname ;
    /**
     * @return the uname
     */
    public String getUname() {
        return uname;
    }

    /**
     * @param uname the uname to set
     */
    public void setUname(String uname) {
        this.uname = uname;
    }

    public Jclass() {
        this.uname = null;
    }

    public static void main(String[] args) {

    }
}

JSP file: sample.jsp

    <%@ page language="java"
    import="java.util.*,java.io.*"
    pageEncoding="ISO-8859-1"%>

<jsp:directive.page import="Jclasspackage.Jclass.java" />   
<% Jclass jc = new Jclass();
String username = (String)request.getAttribute("un")
jc.setUname(username);
%>

-----------------

In this way you can access the username in the java file using "this.username" in the class

At the risk of irritating you;

You're asking the wrong question. You don't need a reason NOT to deviate from the defaults, but the other way around. You need a reason to do so. Timeouts are absolutely essential when running a web server and to disable that setting without a reason is inherently contrary to good practice, even if it's running on a web server that happens to have a timeout directive of its own.

Now, as for the real answer; probably it doesn't matter at all in this particular case, but it's bad practice to go by the setting of a separate system. What if the script is later run on a different server with a different timeout? If you can safely say that it will never happen, fine, but good practice is largely about accounting for seemingly unlikely events and not unnecessarily tying together the settings and functionality of completely different systems. The dismissal of such principles is responsible for a lot of pointless incompatibilities in the software world. Almost every time, they are unforeseen.

What if the web server later is set to run some other runtime environment which only inherits the timeout setting from the web server? Let's say for instance that you later need a 15-year-old CGI program written in C++ by someone who moved to a different continent, that has no idea of any timeout except the web server's. That might result in the timeout needing to be changed and because PHP is pointlessly relying on the web server's timeout instead of its own, that may cause problems for the PHP script. Or the other way around, that you need a lesser web server timeout for some reason, but PHP still needs to have it higher.

It's just not a good idea to tie the PHP functionality to the web server because the web server and PHP are responsible for different roles and should be kept as functionally separate as possible. When the PHP side needs more processing time, it should be a setting in PHP simply because it's relevant to PHP, not necessarily everything else on the web server.

In short, it's just unnecessarily conflating the matter when there is no need to.

Last but not least, 'stillstanding' is right; you should at least rather use set_time_limit() than ini_set().

Hope this wasn't too patronizing and irritating. Like I said, probably it's fine under your specific circumstances, but it's good practice to not assume your circumstances to be the One True Circumstance. That's all. :)

Some Bash tricks I use to set variables from commands

Sorry, there is a loong answer, but as bash is a shell, where the main goal is to run other unix commands and react to resut code and/or output, ( commands are often piped filter, etc... ).

Storing command output in variables is something basic and fundamental.

Therefore, depending on

• compatibility (posix)
• kind of output (filter(s))
• number of variable to set (split or interpret)
• execution time (monitoring)
• error trapping
• repeatability of request (see long running background process, further)
• interactivity (considering user input while reading from another input file descriptor)
• do I miss something?

First simple, old, and compatible way

myPi=`echo '4*a(1)' | bc -l`
echo $myPi 
3.14159265358979323844

Mostly compatible, second way

As nesting could become heavy, parenthesis was implemented for this

myPi=$(bc -l <<<'4*a(1)')

Nested sample:

SysStarted=$(date -d "$(ps ho lstart 1)" +%s)
echo $SysStarted 
1480656334

bash features

Reading more than one variable (with Bashisms)

df -k /
Filesystem     1K-blocks   Used Available Use% Mounted on
/dev/dm-0         999320 529020    401488  57% /

If I just want a used value:

array=($(df -k /))

you could see an array variable:

declare -p array
declare -a array='([0]="Filesystem" [1]="1K-blocks" [2]="Used" [3]="Available" [
4]="Use%" [5]="Mounted" [6]="on" [7]="/dev/dm-0" [8]="999320" [9]="529020" [10]=
"401488" [11]="57%" [12]="/")'

Then:

echo ${array[9]}
529020

But I often use this:

{ read foo ; read filesystem size using avail prct mountpoint ; } < <(df -k /)
echo $using
529020

The first read foo will just skip header line, but in only one command, you will populate 7 different variables:

declare -p avail filesystem foo mountpoint prct size using
declare -- avail="401488"
declare -- filesystem="/dev/dm-0"
declare -- foo="Filesystem     1K-blocks   Used Available Use% Mounted on"
declare -- mountpoint="/"
declare -- prct="57%"
declare -- size="999320"
declare -- using="529020"

Or

{ read -a head;varnames=(${head[@]//[K1% -]});varnames=(${head[@]//[K1% -]});
  read ${varnames[@],,} ; } < <(LANG=C df -k /)

Then:

declare -p varnames ${varnames[@],,} 
declare -a varnames=([0]="Filesystem" [1]="blocks" [2]="Used" [3]="Available" [4]="Use" [5]="Mounted" [6]="on")
declare -- filesystem="/dev/dm-0"
declare -- blocks="999320"
declare -- used="529020"
declare -- available="401488"
declare -- use="57%"
declare -- mounted="/"
declare -- on=""

Or even:

{ read foo ; read filesystem dsk[{6,2,9}] prct mountpoint ; } < <(df -k /)
declare -p mountpoint dsk
declare -- mountpoint="/"
declare -a dsk=([2]="529020" [6]="999320" [9]="401488")

(Note Used and Blocks is switched there: read ... dsk[6] dsk[2] dsk[9] ...)

... will work with associative arrays too: read foo disk[total] disk[used] ...

Dedicated fd using unnamed fifo:

There is an elegent way:

users=()
while IFS=: read -u $list user pass uid gid name home bin ;do
    ((uid>=500)) &&
        printf -v users[uid] "%11d %7d %-20s %s\n" $uid $gid $user $home
done {list}</etc/passwd

Using this way (... read -u $list; ... {list}<inputfile) leave STDIN free for other purposes, like user interaction.

Then

echo -n "${users[@]}"
       1000    1000 user         /home/user
...
      65534   65534 nobody       /nonexistent

and

echo ${!users[@]}
1000 ... 65534

echo -n "${users[1000]}"
      1000    1000 user       /home/user

This could be used with static files or even /dev/tcp/xx.xx.xx.xx/yyy with x for ip address or hostname and y for port number:

{
    read -u $list -a head          # read header in array `head`
    varnames=(${head[@]//[K1% -]}) # drop illegal chars for variable names
    while read -u $list ${varnames[@],,} ;do
        ((pct=available*100/(available+used),pct<10)) &&
            printf "WARN: FS: %-20s on %-14s %3d <10 (Total: %11u, Use: %7s)\n" \
                "${filesystem#*/mapper/}" "$mounted" $pct $blocks "$use"
     done
 } {list}< <(LANG=C df -k)

And of course with inline documents:

while IFS=\; read -u $list -a myvar ;do
    echo ${myvar[2]}
done {list}<<"eof"
foo;bar;baz
alice;bob;charlie
$cherry;$strawberry;$memberberries
eof

Sample function for populating some variables:

#!/bin/bash

declare free=0 total=0 used=0

getDiskStat() {
    local foo
    {
        read foo
        read foo total used free foo
    } < <(
        df -k ${1:-/}
    )
}

getDiskStat $1
echo $total $used $free

Nota: declare line is not required, just for readability.

About sudo cmd | grep ... | cut ...

shell=$(cat /etc/passwd | grep $USER | cut -d : -f 7)
echo $shell
/bin/bash

(Please avoid useless cat! So this is just one fork less:

shell=$(grep $USER </etc/passwd | cut -d : -f 7)

All pipes (|) implies forks. Where another process have to be run, accessing disk, libraries calls and so on.

So using sed for sample, will limit subprocess to only one fork:

shell=$(sed </etc/passwd "s/^$USER:.*://p;d")
echo $shell

And with Bashisms:

But for many actions, mostly on small files, Bash could do the job itself:

while IFS=: read -a line ; do
    [ "$line" = "$USER" ] && shell=${line[6]}
  done </etc/passwd
echo $shell
/bin/bash

or

while IFS=: read loginname encpass uid gid fullname home shell;do
    [ "$loginname" = "$USER" ] && break
  done </etc/passwd
echo $shell $loginname ...

Going further about variable splitting...

Have a look at my answer to How do I split a string on a delimiter in Bash?

Alternative: reducing forks by using backgrounded long-running tasks

In order to prevent multiple forks like

myPi=$(bc -l <<<'4*a(1)'
myRay=12
myCirc=$(bc -l <<<" 2 * $myPi * $myRay ")

or

myStarted=$(date -d "$(ps ho lstart 1)" +%s)
mySessStart=$(date -d "$(ps ho lstart $$)" +%s)

This work fine, but running many forks is heavy and slow.

And commands like date and bc could make many operations, line by line!!

See:

bc -l <<<$'3*4\n5*6'
12
30

date -f - +%s < <(ps ho lstart 1 $$)
1516030449
1517853288

So we could use a long running background process to make many jobs, without having to initiate a new fork for each request.

Under bash, there is a built-in function: coproc:

coproc bc -l
echo 4*3 >&${COPROC[1]}
read -u $COPROC answer
echo $answer
12

echo >&${COPROC[1]} 'pi=4*a(1)'
ray=42.0
printf >&${COPROC[1]} '2*pi*%s\n' $ray
read -u $COPROC answer
echo $answer
263.89378290154263202896

printf >&${COPROC[1]} 'pi*%s^2\n' $ray
read -u $COPROC answer
echo $answer
5541.76944093239527260816

As bc is ready, running in background and I/O are ready too, there is no delay, nothing to load, open, close, before or after operation. Only the operation himself! This become a lot quicker than having to fork to bc for each operation!

Border effect: While bc stay running, they will hold all registers, so some variables or functions could be defined at initialisation step, as first write to ${COPROC[1]}, just after starting the task (via coproc).

Into a function newConnector

You may found my newConnector function on GitHub.Com or on my own site (Note on GitHub: there are two files on my site. Function and demo are bundled into one uniq file which could be sourced for use or just run for demo.)

Sample:

source shell_connector.sh

tty
/dev/pts/20

ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
  29019 pts/20   Ss     0:00 bash
  30745 pts/20   R+     0:00  \_ ps --tty pts/20 fw

newConnector /usr/bin/bc "-l" '3*4' 12

ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
  29019 pts/20   Ss     0:00 bash
  30944 pts/20   S      0:00  \_ /usr/bin/bc -l
  30952 pts/20   R+     0:00  \_ ps --tty pts/20 fw

declare -p PI
bash: declare: PI: not found

myBc '4*a(1)' PI
declare -p PI
declare -- PI="3.14159265358979323844"

The function myBc lets you use the background task with simple syntax, and for date:

newConnector /bin/date '-f - +%s' @0 0
myDate '2000-01-01'
  946681200
myDate "$(ps ho lstart 1)" boottime
myDate now now ; read utm idl </proc/uptime
myBc "$now-$boottime" uptime
printf "%s\n" ${utm%%.*} $uptime
  42134906
  42134906

ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
  29019 pts/20   Ss     0:00 bash
  30944 pts/20   S      0:00  \_ /usr/bin/bc -l
  32615 pts/20   S      0:00  \_ /bin/date -f - +%s
   3162 pts/20   R+     0:00  \_ ps --tty pts/20 fw

From there, if you want to end one of background processes, you just have to close its fd:

eval "exec $DATEOUT>&-"
eval "exec $DATEIN>&-"
ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
   4936 pts/20   Ss     0:00 bash
   5256 pts/20   S      0:00  \_ /usr/bin/bc -l
   6358 pts/20   R+     0:00  \_ ps --tty pts/20 fw

which is not needed, because all fd close when the main process finishes.

Phoronix did some benchmarks about this, but it is about a snapshot version of Clang/LLVM from a few months back. The results being that things were more-or-less a push; neither GCC nor Clang is definitively better in all cases.

Since you'd use the latest Clang, it's maybe a little less relevant. Then again, GCC 4.6 is slated to have some major optimizations for Core 2 and i7, apparently.

I figure Clang's faster compilation speed will be nicer for original developers, and then when you push the code out into the world, Linux distro/BSD/etc. end-users will use GCC for the faster binaries.

I had mine solved by overriding the branch:

My case: I wanted to override whatever code is in the develop with version_2.

1. delete the local copy of conflicting branch:

git checkout version_2
git branch -D develop

2. checkout a fresh branch from the version_2 and force push to git:

git checkout -b `develop`
git push origin `develop`

I didn't need to rebase. But in my case, I didn't need to take code from my old code.

Simply you can use HttpRequest.headers from Django 2.2 onward. Following example is directly taken from the official Django Documentation under Request and response objects section.

>>> request.headers
{'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6', ...}

>>> 'User-Agent' in request.headers
True
>>> 'user-agent' in request.headers
True

>>> request.headers['User-Agent']
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6)
>>> request.headers['user-agent']
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6)

>>> request.headers.get('User-Agent')
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6)
>>> request.headers.get('user-agent')
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6)

Try this code. You just need to implement this code in master page and it will work for you on all the pages

<script type="text/javascript">
    window.onload = function () {
        noBack();
    }
    function noBack() {
        window.history.forward();
    }
</script>
<body  onpageshow="if (event.persisted) noBack();">
</body>

please set dataType config property in your ajax call and give it another try!

another point is you are using ajax call setup configuration properties as string and it is wrong as reference site

$.ajax({

    url : 'http://voicebunny.comeze.com/index.php',
    type : 'GET',
    data : {
        'numberOfWords' : 10
    },
    dataType:'json',
    success : function(data) {              
        alert('Data: '+data);
    },
    error : function(request,error)
    {
        alert("Request: "+JSON.stringify(request));
    }
});

I hope be helpful!

Say you have activity stack like A>B>C>D>E. You are at activity D, and you want to close your app. This is what you wil do -

In Activity from where you want to close (Activity D)-

Intent intent = new Intent(D.this,A.class);
intent.putExtra("exit", "exit");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP| Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(intent);

In your RootActivity (ie your base activity, here Activity A) -

@Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        if (intent.hasExtra("exit")) {
            setIntent(intent);
        }
    }

    @Override
    protected void onResume() {
        super.onResume();
        if (getIntent() != null) {
            if (("exit").equalsIgnoreCase(getIntent().getStringExtra(("exit")))) {
                onBackPressed();
            }
        }
    }

onNewIntent is used because if activity is alive, it will get the first intent that started it. Not the new one. For more detail - Documentation

The error ShowAllData method of Worksheet class failed usually occurs when you try to remove an applied filter when there is not one applied.

I am not certain if you are trying to remove the whole AutoFilter, or just remove any applied filter, but there are different approaches for each.

To remove an applied filter but leave AutoFilter on:

If ActiveSheet.AutoFilterMode Or ActiveSheet.FilterMode Then
    ActiveSheet.ShowAllData
End If

The rationale behind the above code is to test that there is an AutoFilter or whether a filter has been applied (this will also remove advanced filters).

To completely remove the AutoFilter:

ActiveSheet.AutoFilterMode = False

In the above case, you are simply disabling the AutoFilter completely.

You can use java.util.Calendar class to get time in milliseconds. Example:

Calendar cal = Calendar.getInstance();
int milliSec = cal.get(Calendar.MILLISECOND);
// print milliSec

java.util.Date date = cal.getTime();
System.out.println("Output: " +  new SimpleDateFormat("yyyy/MM/dd-HH:mm:ss:SSS").format(date));

Subversion implicitly has the remote repository associated with it at all times. Git, on the other hand, allows many "remotes", each of which represents a single remote place you can push to or pull from.

You need to add a remote for the GitHub repository to your local repository, then use git push ${remote} or git pull ${remote} to push and pull respectively - or the GUI equivalents.

Pro Git discusses remotes here: http://git-scm.com/book/ch2-5.html

The GitHub help also discusses them in a more "task-focused" way here: http://help.github.com/remotes/

Once you have associated the two you will be able to push or pull branches.

You'll want to look at smart pointers, such as boost's smart pointers.

Instead of

int main()
{ 
    Object* obj = new Object();
    //...
    delete obj;
}

boost::shared_ptr will automatically delete once the reference count is zero:

int main()
{
    boost::shared_ptr<Object> obj(new Object());
    //...
    // destructor destroys when reference count is zero
}

Note my last note, "when reference count is zero, which is the coolest part. So If you have multiple users of your object, you won't have to keep track of whether the object is still in use. Once nobody refers to your shared pointer, it gets destroyed.

This is not a panacea, however. Though you can access the base pointer, you wouldn't want to pass it to a 3rd party API unless you were confident with what it was doing. Lots of times, your "posting" stuff to some other thread for work to be done AFTER the creating scope is finished. This is common with PostThreadMessage in Win32:

void foo()
{
   boost::shared_ptr<Object> obj(new Object()); 

   // Simplified here
   PostThreadMessage(...., (LPARAM)ob.get());
   // Destructor destroys! pointer sent to PostThreadMessage is invalid! Zohnoes!
}

As always, use your thinking cap with any tool...

I have seen a pretty neat article about this... so if you like this:

CREATE PROC [dbo].[spUpdateMarks]
    @inputJSON VARCHAR(MAX)  -- '[{"ID":"1","C":"60","CPP":"60","CS":"60"}]'
AS
BEGIN
    -- Temp table to hold the parsed data
    DECLARE @TempTableVariable TABLE(
        element_id INT,
        sequenceNo INT,
        parent_ID INT,
        [Object_ID] INT,
        [NAME] NVARCHAR(2000),
        StringValue NVARCHAR(MAX),
        ValueType NVARCHAR(10)
    )
    -- Parse JSON string into a temp table
    INSERT INTO @TempTableVariable
    SELECT * FROM parseJSON(@inputJSON)

There is a complete ASP.Net project about this here: http://www.codeproject.com/Articles/788208/Update-Multiple-Rows-of-GridView-using-JSON-in-ASP

Does the user that you are using to connect to the database (user A in this example) have SELECT access on the objects in the PCT schema? Assuming that A does not have this access, you would get the "table or view does not exist" error.

Most likely, you need your DBA to grant user A access to whatever tables in the PCT schema that you need. Something like

GRANT SELECT ON pct.pi_int
   TO a;

Once that is done, you should be able to refer to the objects in the PCT schema using the syntax pct.pi_int as you demonstrated initially in your question. The bracket syntax approach will not work.

In my situation, this error seems to occur only if my client's computer has a strict firewall policy, which prevents my program from communicating with the web service.

So only solution I could find is to catch the error and inform user about changing the firewall settings manually.

Try this example

$json = '{"foo-bar": 12345}';

$obj = json_decode($json);
print $obj->{'foo-bar'}; // 12345

NB - two negatives makes a positive . :)

If the requirement is to copy all files in "\Publish\Appfolder" into the parent "\Publish\" folder (inclusive of any subfolders, following works for me) The switch '/s' allows copying of all subfolders, recursively.

xcopy src\main\Publish\Appfolder\*.* /s src\main\Publish\

The body's size is dynamic, it is only as large as the size of its contents. In the css file you could use: * {background-color: black} // All elements now have a black background.

or

html {background-color: black} // The page now have a black background, all elements remain the same.

The provided examples, using csv modules, are great! Besides, you can always simply write to a text file using formatted strings, like the following tentative example:

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

out = open('out.csv', 'w')
for row in l:
    for column in row:
        out.write('%d;' % column)
    out.write('\n')
out.close()

I used ; as separator, because it works best with Excell (one of your requirements).

Hope it helps!

Use the random module: http://docs.python.org/library/random.html

import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)

This samples the two values without replacement (so the two values are different).

• < stands for the less-than sign: <
• > stands for the greater-than sign: >
• ≤ stands for the less-than or equals sign: =
• ≥ stands for the greater-than or equals sign: =

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

The issue seems to be resolved in Python version 3.4.2.

testVar = input("Ask user for something.")

Will work fine.

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);

Where str is your XML string. See the MSDN article for more info.

I would recommend a less hackish and more formal way to force a reflow: use forceDOMReflowJS. In your case, your code would look as follows.

sel = document.getElementById('my_id');
forceReflowJS( sel );
return false;

If you would like to replace but still keeping the style of previous str. It is possible.

For example: highlight the string "test asdasd TEST asd tEst asdasd".

sentence = "test asdasd TEST asd tEst asdasd"
result = re.sub(
  '(test)', 
  r'<b>\1</b>',  # \1 here indicates first matching group.
  sentence, 
  flags=re.IGNORECASE)

test asdasd TEST asd tEst asdasd

very easy 1- install pakage :

pip install mouse

2- add library to project :

import mouse

3- use it for example :

mouse.right_click()

in this url describe all function that you can use it :

A Promise emits a single event when an async activity finishes or fails.

An Observable is like a Stream (in many languages) and permits to pass at least zero or more events where the callback is required for every event.

Frequently Observable is preferred over Promise since it gives the highlights of Promise and more. With Observable it doesn't matter if you need to handle 0, 1, or various events. You can use the similar API for each case.

Promise: promise emits a single value

For example:

const numberPromise = new Promise((resolve) => {
    resolve(5);
    resolve(10);
});

numberPromise.then(value => console.log(value));
// still prints only 5

Observable: Emits multiple values over a period of time

For example:

  const numberObservable = new Observable((observer) => {
        observer.next(5);
        observer.next(10);
    });

numberObservable.subscribe(value => console.log(value));
// prints 5 and 10

we can think of an observable like a stream which emits multiple values over a period of time and the same callback function is called for each item emitted so with an observable we can use the same API to handled asynchronous data. whether that data is transmitted as a single value or multiple values over some stretch of time.

Promise:

• A promise is Not Lazy
• A Promise cannot be cancelled

Observable:

• Observable is Lazy. The "Observable" is slow. It isn't called until we are subscribed to it.
• An Observable can be cancelled by using the unsubscribe() method
• An addition Observable provides many powerful operators like map, foreach, filter, reduce, retry, retryWhen etc.

Angular Promises vs Observables

As Tmdean correctly pointed out you can use the Mid() function. The MSDN Library also has a great reference section on VBScript which you can find here:

VBScript Language Reference (MSDN Library)

android:layout_gravity="bottom"

Example. To find number of vowels within the string

var word='Web Development Tutorial';
var vowels='[aeiou]'; 
var re = new RegExp(vowels, 'gi');
var arr = word.match(re);
document.write(arr.length);

Try setting the file path using (for anaconda3)...

export PATH=~/anaconda3/bin:$PATH

Then check whether it worked with...

conda --version

This worked for me when 'conda' was returning 'command not found'.

What you are trying should work according to the MSDN doc's for .Net 2.0. You could also try a try/catch right in main around your entry point for the console app.

static void Main(string[] args)
{
    try
    {
        // Start Working
    }
    catch (Exception ex)
    {
        // Output/Log Exception
    }
    finally
    {
        // Clean Up If Needed
    }
}

And now your catch will handle anything not caught (in the main thread). It can be graceful and even restart where it was if you want, or you can just let the app die and log the exception. You woul add a finally if you wanted to do any clean up. Each thread will require its own high level exception handling similar to the main.

Edited to clarify the point about threads as pointed out by BlueMonkMN and shown in detail in his answer.

You were almost there : just add theme(legend.title=element_blank())

ggplot(df, aes(x, y, colour=g)) +
  geom_line(stat="identity") + 
  theme(legend.position="bottom") +
  theme(legend.title=element_blank())

This page on Cookbook for R gives plenty of details on how to customize legends.

Using requests:

import requests
url = 'http://ES_search_demo.com/document/record/_search?pretty=true'
data = '''{
  "query": {
    "bool": {
      "must": [
        {
          "text": {
            "record.document": "SOME_JOURNAL"
          }
        },
        {
          "text": {
            "record.articleTitle": "farmers"
          }
        }
      ],
      "must_not": [],
      "should": []
    }
  },
  "from": 0,
  "size": 50,
  "sort": [],
  "facets": {}
}'''
response = requests.post(url, data=data)

Depending on what kind of response your API returns, you will then probably want to look at response.text or response.json() (or possibly inspect response.status_code first). See the quickstart docs here, especially this section.

The best way is to close the session is: if there is no response for that session after particular interval of time. then close. Please see this post and I hope it will resolve the issue. "How to change the session timeout in PHP?"

You need to use the Disposable Pattern like this:

private bool _disposed = false;

protected virtual void Dispose(bool disposing)
{
    if (!_disposed)
    {
        if (disposing)
        {
            // Dispose any managed objects
            // ...
        }

        // Now disposed of any unmanaged objects
        // ...

        _disposed = true;
    }
}

public void Dispose()
{
    Dispose(true);
    GC.SuppressFinalize(this);  
}

// Destructor
~YourClassName()
{
    Dispose(false);
}

Do everything suggested by ziesemer.

You may also want to :

• Stop the Oracle-related services (before deleting them from the registry).
• In the registry, look not only for entries named "Oracle" but also e.g. for "ODP".

First let's understand what big O, big Theta and big Omega are. They are all sets of functions.

Big O is giving upper asymptotic bound, while big Omega is giving a lower bound. Big Theta gives both.

Everything that is ?(f(n)) is also O(f(n)), but not the other way around.
T(n) is said to be in ?(f(n)) if it is both in O(f(n)) and in Omega(f(n)).
In sets terminology, ?(f(n)) is the intersection of O(f(n)) and Omega(f(n))

For example, merge sort worst case is both O(n*log(n)) and Omega(n*log(n)) - and thus is also ?(n*log(n)), but it is also O(n^2), since n^2 is asymptotically "bigger" than it. However, it is not ?(n^2), Since the algorithm is not Omega(n^2).

A bit deeper mathematic explanation

O(n) is asymptotic upper bound. If T(n) is O(f(n)), it means that from a certain n0, there is a constant C such that T(n) <= C * f(n). On the other hand, big-Omega says there is a constant C2 such that T(n) >= C2 * f(n))).

Do not confuse!

Not to be confused with worst, best and average cases analysis: all three (Omega, O, Theta) notation are not related to the best, worst and average cases analysis of algorithms. Each one of these can be applied to each analysis.

We usually use it to analyze complexity of algorithms (like the merge sort example above). When we say "Algorithm A is O(f(n))", what we really mean is "The algorithms complexity under the worst¹ case analysis is O(f(n))" - meaning - it scales "similar" (or formally, not worse than) the function f(n).

Why we care for the asymptotic bound of an algorithm?

Well, there are many reasons for it, but I believe the most important of them are:

1. It is much harder to determine the exact complexity function, thus we "compromise" on the big-O/big-Theta notations, which are informative enough theoretically.
2. The exact number of ops is also platform dependent. For example, if we have a vector (list) of 16 numbers. How much ops will it take? The answer is: it depends. Some CPUs allow vector additions, while other don't, so the answer varies between different implementations and different machines, which is an undesired property. The big-O notation however is much more constant between machines and implementations.

To demonstrate this issue, have a look at the following graphs:

It is clear that f(n) = 2*n is "worse" than f(n) = n. But the difference is not quite as drastic as it is from the other function. We can see that f(n)=logn quickly getting much lower than the other functions, and f(n) = n^2 is quickly getting much higher than the others.
So - because of the reasons above, we "ignore" the constant factors (2* in the graphs example), and take only the big-O notation.

In the above example, f(n)=n, f(n)=2*n will both be in O(n) and in Omega(n) - and thus will also be in Theta(n).
On the other hand - f(n)=logn will be in O(n) (it is "better" than f(n)=n), but will NOT be in Omega(n) - and thus will also NOT be in Theta(n).
Symetrically, f(n)=n^2 will be in Omega(n), but NOT in O(n), and thus - is also NOT Theta(n).

¹Usually, though not always. when the analysis class (worst, average and best) is missing, we really mean the worst case.

you can remove last comma from a string by using slice() method, find the below example:

var strVal = $.trim($('.txtValue').val());
var lastChar = strVal.slice(-1);
if (lastChar == ',') {
    strVal = strVal.slice(0, -1);
}

Here is an Example

function myFunction() {_x000D_
 var strVal = $.trim($('.txtValue').text());_x000D_
 var lastChar = strVal.slice(-1);_x000D_
 if (lastChar == ',') { // check last character is string_x000D_
  strVal = strVal.slice(0, -1); // trim last character_x000D_
  $("#demo").text(strVal);_x000D_
 }_x000D_
}

map(&:name) takes an enumerable object (tags in your case) and runs the name method for each element/tag, outputting each returned value from the method.

It is a shorthand for

array.map { |element| element.name }

which returns the array of element(tag) names
