I landed on this question as I was looking for a clean iterator of columns only (Series, no names).

Unless I am mistaken, there is no such thing, which, if true, is a bit annoying. In particular, one would sometimes like to assign a few individual columns (Series) to variables, e.g.:

x, y = df[['x', 'y']]  # does not work

There is df.items() that gets close, but it gives an iterator of tuples (column_name, column_series). Interestingly, there is a corresponding df.keys() which returns df.columns, i.e. the column names as an Index, so a, b = df[['x', 'y']].keys() assigns properly a='x' and b='y'. But there is no corresponding df.values(), and for good reason, as df.values is a property and returns the underlying numpy array.

One (inelegant) way is to do:

x, y = (v for _, v in df[['x', 'y']].items())

but it's less pythonic than I'd like.

I don't know what the .tex extension on your file means. If we are saying that it is any file with any extension you have several methods of reading it.

I have to assume you are using windows because you have mentioned notepad++.

1. Use notepad++. Right click on the file and choose "edit with notepad++"

2. Use notepad Change the filename extension to .txt and double click the file.

3. Use command prompt. Open the folder that your file is in. Hold down shift and right click. (not on the file, but in the folder that the file is in.) Choose "open command window here" from the command prompt type: "type filename.tex"

If these don't work, I would need more detail as to how they are not working. Errors that you may be getting or what you may expect to be in the file might help.

Firefox doesn't seem to support the clear search field functionality... I found this pure CSS solution that works nicely: Textbox with a clear button completely in CSS | Codepen | 2013. The magic happens at

.search-box:not(:valid) ~ .close-icon {
    display: none;
}

body {
    background-color: #f1f1f1;
    font-family: Helvetica,Arial,Verdana;

}
h2 {
    color: green;
    text-align: center;
}
.redfamily {
    color: red; 
}
.search-box,.close-icon,.search-wrapper {
    position: relative;
    padding: 10px;
}
.search-wrapper {
    width: 500px;
    margin: auto;
}
.search-box {
    width: 80%;
    border: 1px solid #ccc;
  outline: 0;
  border-radius: 15px;
}
.search-box:focus {
    box-shadow: 0 0 15px 5px #b0e0ee;
    border: 2px solid #bebede;
}
.close-icon {
    border:1px solid transparent;
    background-color: transparent;
    display: inline-block;
    vertical-align: middle;
  outline: 0;
  cursor: pointer;
}
.close-icon:after {
    content: "X";
    display: block;
    width: 15px;
    height: 15px;
    position: absolute;
    background-color: #FA9595;

    padding: 2px;
    border-radius: 50%;
    text-align: center;
    color: white;
    font-weight: normal;
    font-size: 12px;
    box-shadow: 0 0 2px #E50F0F;
    cursor: pointer;
}
.search-box:not(:valid) ~ .close-icon {
    display: none;
}

<h2>

    <input type="text" name="focus" required class="search-box" placeholder="Enter search term" />
        <button class="close-icon" type="reset"></button>

I needed more functionality and added this jQuery in my code:

$('.close-icon').click(function(){ /* my code */ });

I don't understand

days, hours, minutes = td.days, td.seconds // 3600, td.seconds // 60 % 60

how about this

days, hours, minutes = td.days, td.seconds // 3600, td.seconds % 3600 / 60.0

You get minutes and seconds of a minute as a float.

What you want to do is actually again a groupby (on the result of the first groupby): sort and take the first three elements per group.

Starting from the result of the first groupby:

In [60]: df_agg = df.groupby(['job','source']).agg({'count':sum})

We group by the first level of the index:

In [63]: g = df_agg['count'].groupby('job', group_keys=False)

Then we want to sort ('order') each group and take the first three elements:

In [64]: res = g.apply(lambda x: x.sort_values(ascending=False).head(3))

However, for this, there is a shortcut function to do this, nlargest:

In [65]: g.nlargest(3)
Out[65]:
job     source
market  A         5
        D         4
        B         3
sales   E         7
        C         6
        B         4
dtype: int64

So in one go, this looks like:

df_agg['count'].groupby('job', group_keys=False).nlargest(3)

You can also check the .Any() method:

if (!YourResult.Any())

Just a note that .Any will still retrieve the records from the database; doing a .FirstOrDefault()/.Where() will be just as much overhead but you would then be able to catch the object(s) returned from the query

To automatically convert spaces to tabs on save, add the following Python script to a newly created subfolder called "UnexpandTabsOnSave" within "$SUBLIME_HOME$\Packages\":

import sublime, sublime_plugin, os

class ConvertSpacesToTabsOnSave( sublime_plugin.EventListener ):
  # Run Sublime's 'unexpand_tabs' command when saving any file
  def on_pre_save( self, view ):
    view.window().run_command( 'unexpand_tabs' )

Thank you for the initial resource.

wxWidgets has a very rich string API wxString

it can be done with (using the case conversion way)

int Contains(const wxString& SpecProgramName, const wxString& str)
{
  wxString SpecProgramName_ = SpecProgramName.Upper();
  wxString str_ = str.Upper();
  int found = SpecProgramName.Find(str_);
  if (wxNOT_FOUND == found)
  {
    return 0;
  }
  return 1;
}

I found a solution to deproxy a class using standard Java and JPA API. Tested with hibernate, but does not require hibernate as a dependency and should work with all JPA providers.

Onle one requirement - its necessary to modify parent class (Address) and add a simple helper method.

General idea: add helper method to parent class which returns itself. when method called on proxy, it will forward the call to real instance and return this real instance.

Implementation is a little bit more complex, as hibernate recognizes that proxied class returns itself and still returns proxy instead of real instance. Workaround is to wrap returned instance into a simple wrapper class, which has different class type than the real instance.

In code:

class Address {
   public AddressWrapper getWrappedSelf() {
       return new AddressWrapper(this);
   }
...
}

class AddressWrapper {
    private Address wrappedAddress;
...
}

To cast Address proxy to real subclass, use following:

Address address = dao.getSomeAddress(...);
Address deproxiedAddress = address.getWrappedSelf().getWrappedAddress();
if (deproxiedAddress instanceof WorkAddress) {
WorkAddress workAddress = (WorkAddress)deproxiedAddress;
}

Setting the style.zIndex property has no effect on non-positioned elements, that is, the element must be either absolutely positioned, relatively positioned, or fixed.

So I would try:

$(this).parent().css('position', 'relative');
$(this).parent().css('z-index', 3000);

Since you haven't made any commits yet, you can save all your changes to the stash, create and switch to a new branch, then pop those changes back into your working tree:

git stash  # save local modifications to new stash
git checkout -b topic/newbranch
git stash pop  # apply stash and remove it from the stash list

1. You need

   @ManagedBean(name="userBean")

2. Make sure you have getUser() method.

3. Type of setUser() method should be void.

4. Make sure that User class has proper setters and getters as well.

run this

// you'll see that it prints Object
console.log(typeof document.location);

you want document.location.toString() or document.location.href

I did tests with buffer size, running this code

using (var stream = new BufferedStream(File.OpenRead(file), bufferSize))
{
    SHA256Managed sha = new SHA256Managed();
    byte[] checksum = sha.ComputeHash(stream);
    return BitConverter.ToString(checksum).Replace("-", String.Empty).ToLower();
}

And I tested with a file of 29½ GB in size, the results were

• 10.000: 369,24s
• 100.000: 362,55s
• 1.000.000: 361,53s
• 10.000.000: 434,15s
• 100.000.000: 435,15s
• 1.000.000.000: 434,31s
• And 376,22s when using the original, none buffered code.

I am running an i5 2500K CPU, 12 GB ram and a OCZ Vertex 4 256 GB SSD drive.

So I thought, what about a standard 2TB harddrive. And the results were like this

• 10.000: 368,52s
• 100.000: 364,15s
• 1.000.000: 363,06s
• 10.000.000: 678,96s
• 100.000.000: 617,89s
• 1.000.000.000: 626,86s
• And for none buffered 368,24

So I would recommend either no buffer or a buffer of max 1 mill.

Postgresql historically doesn't support procedural code at the command level - only within functions. However, in Postgresql 9, support has been added to execute an inline code block that effectively supports something like this, although the syntax is perhaps a bit odd, and there are many restrictions compared to what you can do with SQL Server. Notably, the inline code block can't return a result set, so can't be used for what you outline above.

In general, if you want to write some procedural code and have it return a result, you need to put it inside a function. For example:

CREATE OR REPLACE FUNCTION somefuncname() RETURNS int LANGUAGE plpgsql AS $$
DECLARE
  one int;
  two int;
BEGIN
  one := 1;
  two := 2;
  RETURN one + two;
END
$$;
SELECT somefuncname();

The PostgreSQL wire protocol doesn't, as far as I know, allow for things like a command returning multiple result sets. So you can't simply map T-SQL batches or stored procedures to PostgreSQL functions.

And there is your answer =) Try to break it, you can't!!!

The best way is to use an And clause in your While statement

Dim count as Integer
count =0
While True And count <= 10
    count=count+1
    Debug.Print(count)
Wend

The main difference between the two is where it is stored and how it is accessed.

$.fn.attr stores the information directly on the element in attributes which are publicly visible upon inspection, and also which are available from the element's native API.

$.fn.data stores the information in a ridiculously obscure place. It is located in a closed over local variable called data_user which is an instance of a locally defined function Data. This variable is not accessible from outside of jQuery directly.

Data set with attr()

• accessible from $(element).attr('data-name')
• accessible from element.getAttribute('data-name'),
• if the value was in the form of data-name also accessible from $(element).data(name) and element.dataset['name'] and element.dataset.name
• visible on the element upon inspection
• cannot be objects

Data set with .data()

• accessible only from .data(name)
• not accessible from .attr() or anywhere else
• not publicly visible on the element upon inspection
• can be objects

        $IP = getenv('HTTP_X_FORWARDED_FOR');

n=int(input("Enter the number"))
if n==1 :  #because the below logic doesn't work on 1

    if n%i==0 :
        n1=i  #get factor
        for b in range(2,n+1): #check if it is prime
            if ((n1%b)==0) & (n1==b):
                print(n1)
            elif (n1%b)==0 or n1<b:  #if not then pass
                break

i am sure this is the worst logic but it's all the knowledge i have in .py this program will get a number from user and prints all of it's factors numbers that are prime like for 12 it will give 2,3

I also wanted to clarify that if you have complex url parameters to build, you will need to build them manually. ie if your query is example.com/?latlng=-37,147, instead of providing the lat and lng values individually, you will need to build the latlng string externally, then provide it as a parameter, ie:

public interface LocationService {    
    @GET("/example/")
    void getLocation(@Query(value="latlng", encoded=true) String latlng);
}

Note the encoded=true is necessary, otherwise retrofit will encode the comma in the string parameter. Usage:

String latlng = location.getLatitude() + "," + location.getLongitude();
service.getLocation(latlng);

Why would you want to convert key strokes to text? Add a button that sends the text inside the textarea to the server when clicked. You can get the text using the value attribute as the poster before has pointed out, or using jQuery's API:

$('input#mybutton').click(function() {
    var text = $('textarea#mytextarea').val();
    //send to server and process response
});

Run Spring Boot app using Maven

You can also use Maven plugin to run your Spring Boot app. Use the below example to run your Spring Boot app with Maven plugin:

mvn spring-boot:run

Run Spring Boot App with Gradle

And if you use Gradle you can run the Spring Boot app with the following command:

gradle bootRun

exec('wget http://<url to the php script>') worked for me.

It enable me to integrate two php files that were designed as web pages and run them as code to do work without affecting the calling page

NSArray *array = mutableArray;

This [mutableArray copy] antipattern is all over sample code. Stop doing so for throwaway mutable arrays that are transient and get deallocated at the end of the current scope.

There is no way the runtime could optimize out the wasteful copying of a mutable array that is just about to go out of scope, decrefed to 0 and deallocated for good.

For SQL Server 2012, or later, an easier solution is to use FORMAT ()^{Documentation}.
EG:

SELECT Format(1234567.8, '##,##0') 

Results in: 1,234,568

I was looking to find the answer to this question too, but the accepted answer was breaking for me. Apparently using window.innerWidth isn't portable. It does work in some browsers, but I noticed Firefox didn't like it.

Gregg Tavares posted a great resource here that addresses this issue directly: http://webglfundamentals.org/webgl/lessons/webgl-anti-patterns.html (See anti-pattern #'s 3 and 4).

Using canvas.clientWidth instead of window.innerWidth seems to work nicely.

Here's Gregg's suggested render loop:

function resize() {
  var width = gl.canvas.clientWidth;
  var height = gl.canvas.clientHeight;
  if (gl.canvas.width != width ||
      gl.canvas.height != height) {
     gl.canvas.width = width;
     gl.canvas.height = height;
     return true;
  }
  return false;
}

var needToRender = true;  // draw at least once
function checkRender() {
   if (resize() || needToRender) {
     needToRender = false;
     drawStuff();
   }
   requestAnimationFrame(checkRender);
}
checkRender();

Even though Logger.log() is technically the correct way to output something to the console, it has a few annoyances:

1. The output can be an unstructured mess and hard to quickly digest.
2. You have to first run the script, then click View / Logs, which is two extra clicks (one if you remember the Ctrl+Enter keyboard shortcut).
3. You have to insert Logger.log(playerArray), and then after debugging you'd probably want to remove Logger.log(playerArray), hence an additional 1-2 more steps.
4. You have to click on OK to close the overlay (yet another extra click).

Instead, whenever I want to debug something I add breakpoints (click on line number) and press the Debug button (bug icon). Breakpoints work well when you are assigning something to a variable, but not so well when you are initiating a variable and want to peek inside of it at a later point, which is similar to what the op is trying to do. In this case, I would force a break condition by entering "x" (x marks the spot!) to throw a run-time error:

Compare with viewing Logs:

The Debug console contains more information and is a lot easier to read than the Logs overlay. One minor benefit with this method is that you never have to worry about polluting your code with a bunch of logging commands if keeping clean code is your thing. Even if you enter "x", you are forced to remember to remove it as part of the debugging process or else your code won't run (built-in cleanup measure, yay).

As odd as it sound when you want to permit nested attributes you do specify the attributes of nested object within an array. In your case it would be

Update as suggested by @RafaelOliveira

params.require(:measurement)
      .permit(:name, :groundtruth => [:type, :coordinates => []])

On the other hand if you want nested of multiple objects then you wrap it inside a hash… like this

params.require(:foo).permit(:bar, {:baz => [:x, :y]})

Rails actually have pretty good documentation on this: http://api.rubyonrails.org/classes/ActionController/Parameters.html#method-i-permit

For further clarification, you could look at the implementation of permit and strong_parameters itself: https://github.com/rails/rails/blob/master/actionpack/lib/action_controller/metal/strong_parameters.rb#L246-L247

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.

  $("#checkbox").change(function(e) {

  if ($(this).prop('checked')){
    console.log('checked');
  }
});

Maybe the sample is oversimplified, but you don't need the Java stream API here. Just use the Map directly.

 List<String> list1 = id1.get(1); // this will return the list from your map

Wait until angular has evaluated the variable

I had a lot of fiddling around with this, and couldn't get it to work even with the variable defined with "=" in the scope. Here's three solutions depending on your situation.

Solution #1

I found that the variable was not evaluated by angular yet when it was passed to the directive. This means that you can access it and use it in the template, but not inside the link or app controller function unless we wait for it to be evaluated.

If your variable is changing, or is fetched through a request, you should use $observe or $watch:

app.directive('yourDirective', function () {
    return {
        restrict: 'A',
        // NB: no isolated scope!!
        link: function (scope, element, attrs) {
            // observe changes in attribute - could also be scope.$watch
            attrs.$observe('yourDirective', function (value) {
                if (value) {
                    console.log(value);
                    // pass value to app controller
                    scope.variable = value;
                }
            });
        },
        // the variable is available in directive controller,
        // and can be fetched as done in link function
        controller: ['$scope', '$element', '$attrs',
            function ($scope, $element, $attrs) {
                // observe changes in attribute - could also be scope.$watch
                $attrs.$observe('yourDirective', function (value) {
                    if (value) {
                        console.log(value);
                        // pass value to app controller
                        $scope.variable = value;
                    }
                });
            }
        ]
    };
})
.controller('MyCtrl', ['$scope', function ($scope) {
    // variable passed to app controller
    $scope.$watch('variable', function (value) {
        if (value) {
            console.log(value);
        }
    });
}]);

And here's the html (remember the brackets!):

<div ng-controller="MyCtrl">
    <div your-directive="{{ someObject.someVariable }}"></div>
    <!-- use ng-bind in stead of {{ }}, when you can to avoids FOUC -->
    <div ng-bind="variable"></div>
</div>

Note that you should not set the variable to "=" in the scope, if you are using the $observe function. Also, I found that it passes objects as strings, so if you're passing objects use solution #2 or scope.$watch(attrs.yourDirective, fn) (, or #3 if your variable is not changing).

Solution #2

If your variable is created in e.g. another controller, but just need to wait until angular has evaluated it before sending it to the app controller, we can use $timeout to wait until the $apply has run. Also we need to use $emit to send it to the parent scope app controller (due to the isolated scope in the directive):

app.directive('yourDirective', ['$timeout', function ($timeout) {
    return {
        restrict: 'A',
        // NB: isolated scope!!
        scope: {
            yourDirective: '='
        },
        link: function (scope, element, attrs) {
            // wait until after $apply
            $timeout(function(){
                console.log(scope.yourDirective);
                // use scope.$emit to pass it to controller
                scope.$emit('notification', scope.yourDirective);
            });
        },
        // the variable is available in directive controller,
        // and can be fetched as done in link function
        controller: [ '$scope', function ($scope) {
            // wait until after $apply
            $timeout(function(){
                console.log($scope.yourDirective);
                // use $scope.$emit to pass it to controller
                $scope.$emit('notification', scope.yourDirective);
            });
        }]
    };
}])
.controller('MyCtrl', ['$scope', function ($scope) {
    // variable passed to app controller
    $scope.$on('notification', function (evt, value) {
        console.log(value);
        $scope.variable = value;
    });
}]);

And here's the html (no brackets!):

<div ng-controller="MyCtrl">
    <div your-directive="someObject.someVariable"></div>
    <!-- use ng-bind in stead of {{ }}, when you can to avoids FOUC -->
    <div ng-bind="variable"></div>
</div>

Solution #3

If your variable is not changing and you need to evaluate it in your directive, you can use the $eval function:

app.directive('yourDirective', function () {
    return {
        restrict: 'A',
        // NB: no isolated scope!!
        link: function (scope, element, attrs) {
            // executes the expression on the current scope returning the result
            // and adds it to the scope
            scope.variable = scope.$eval(attrs.yourDirective);
            console.log(scope.variable);

        },
        // the variable is available in directive controller,
        // and can be fetched as done in link function
        controller: ['$scope', '$element', '$attrs',
            function ($scope, $element, $attrs) {
                // executes the expression on the current scope returning the result
                // and adds it to the scope
                scope.variable = scope.$eval($attrs.yourDirective);
                console.log($scope.variable);
            }
         ]
    };
})
.controller('MyCtrl', ['$scope', function ($scope) {
    // variable passed to app controller
    $scope.$watch('variable', function (value) {
        if (value) {
            console.log(value);
        }
    });
}]);

And here's the html (remember the brackets!):

<div ng-controller="MyCtrl">
    <div your-directive="{{ someObject.someVariable }}"></div>
    <!-- use ng-bind instead of {{ }}, when you can to avoids FOUC -->
    <div ng-bind="variable"></div>
</div>

The SOAP WS supports both remote procedure call (i.e. RPC) and message oriented middle-ware (MOM) integration styles. The Restful Web Service supports only RPC integration style.

The SOAP WS is transport protocol neutral. Supports multiple protocols like HTTP(S), Messaging, TCP, UDP SMTP, etc. The REST is transport protocol specific. Supports only HTTP or HTTPS protocols.

The SOAP WS permits only XML data format.You define operations, which tunnels through the POST. The focus is on accessing the named operations and exposing the application logic as a service. The REST permits multiple data formats like XML, JSON data, text, HTML, etc. Any browser can be used because the REST approach uses the standard GET, PUT, POST, and DELETE Web operations. The focus is on accessing the named resources and exposing the data as a service. REST has AJAX support. It can use the XMLHttpRequest object. Good for stateless CRUD (Create, Read, Update, and Delete) operations. GET - represent() POST - acceptRepresention() PUT - storeRepresention() DELETE - removeRepresention()

SOAP based reads cannot be cached. REST based reads can be cached. Performs and scales better. SOAP WS supports both SSL security and WS-security, which adds some enterprise security features like maintaining security right up to the point where it is needed, maintaining identities through intermediaries and not just point to point SSL only, securing different parts of the message with different security algorithms, etc. The REST supports only point-to-point SSL security. The SSL encrypts the whole message, whether all of it is sensitive or not. The SOAP has comprehensive support for both ACID based transaction management for short-lived transactions and compensation based transaction management for long-running transactions. It also supports two-phase commit across distributed resources. The REST supports transactions, but it is neither ACID compliant nor can provide two phase commit across distributed transactional resources as it is limited by its HTTP protocol.

The SOAP has success or retry logic built in and provides end-to-end reliability even through SOAP intermediaries. REST does not have a standard messaging system, and expects clients invoking the service to deal with communication failures by retrying.

I am looking for a way to create a select without repeating the conditional query.

I'm assuming that you don't want to repeat Foo-stuff+bar. You could put your calculation into a derived table:

SELECT CASE WHEN a.TestValue > 2 THEN a.TestValue ELSE 'Fail' END 
FROM (SELECT (Foo-stuff+bar) AS TestValue FROM MyTable) AS a

A common table expression would work just as well:

WITH a AS (SELECT (Foo-stuff+bar) AS TestValue FROM MyTable)
SELECT CASE WHEN a.TestValue > 2 THEN a.TestValue ELSE 'Fail' END    
FROM a

Also, each part of your switch should return the same datatype, so you may have to cast one or more cases.

Assuming your ints are 0, 375, 668,5 and 6:

{
    "Id": "610",
    "Name": "15",
    "Description": "1.99",
    "ItemModList": [
                       0,
                       375,
                       668,
                       5,
                       6
                   ]
}

I suggest that you change "Id": "610" to "Id": 610 since it is a integer/long and not a string. You can read more about the JSON format and examples here http://json.org/

Well, doing using an regular expression will be a lot easier:

    mainUrl = "http://www.mywebsite.com/mypath/to/folder";
    urlParts = /^(?:\w+\:\/\/)?([^\/]+)(.*)$/.exec(mainUrl);
    host = Fragment[1]; // www.mywebsite.com

You could also use the generic function cbind() and lm() without the intercept:

cbind(lm(d$Rate1~-1+d$Name)$coef,lm(d$Rate2~-1+d$Name)$coef)
>               [,1]     [,2]
>d$NameAira 16.33333 47.00000
>d$NameBen  31.33333 50.33333
>d$NameCat  44.66667 54.00000

I like thinking about design pattens in terms of my classes being 'people,' and the patterns are the ways that the people talk to each other.

So, to me the factory pattern is like a hiring agency. You've got someone that will need a variable number of workers. This person may know some info they need in the people they hire, but that's it.

So, when they need a new employee, they call the hiring agency and tell them what they need. Now, to actually hire someone, you need to know a lot of stuff - benefits, eligibility verification, etc. But the person hiring doesn't need to know any of this - the hiring agency handles all of that.

In the same way, using a Factory allows the consumer to create new objects without having to know the details of how they're created, or what their dependencies are - they only have to give the information they actually want.

public interface IThingFactory
{
    Thing GetThing(string theString);
}

public class ThingFactory : IThingFactory
{
    public Thing GetThing(string theString)
    {
        return new Thing(theString, firstDependency, secondDependency);
    }
}

So, now the consumer of the ThingFactory can get a Thing, without having to know about the dependencies of the Thing, except for the string data that comes from the consumer.

I have the same problem that you describe although I'm building up my LatLngBounds as proposed by above. The problem is that things are async and calling map.fitBounds() at the wrong time may leave you with a result like in the Q. The best way I found is to place the call in an idle handler like this:

google.maps.event.addListenerOnce(map, 'idle', function() {
    map.fitBounds(markerBounds);
});

i have solve my same problem

i update my android studio, and i choose not to import my setting from my previous version than that problem appear.

than i realize that i have 2 AndroidStudio folder on my windows account (.AndroidStudio and .AndroidStudio1.2) and on my new .AndroidStudio1.2 folder there are no other.xml file.

than i copy other.xml file from C:\Users\my windows account name.AndroidStudio\config\options to C:\Users\my windows account name.AndroidStudio1.2\config\options

and that how i solve my problem.

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

Swift 4.2 solution with NavigationController

First Step:

Open your info.plist and insert a new key named "View controller-based status bar appearance" or UIViewControllerBasedStatusBarAppearance to YES to let each VC use their own status property.

Second Step

In each VC, override the preferredStatusBarStyle property like this :

override var preferredStatusBarStyle : UIStatusBarStyle {
    return .lightContent //.default for black style
}

Last step

Override the preferredStatusBarStyle property in your custom NavigationController class :

class NavigationController : UINavigationController {

override var preferredStatusBarStyle : UIStatusBarStyle {

    if let topVC = viewControllers.last {
        //return the status property of each VC, look at step 2
        return topVC.preferredStatusBarStyle  
    }

    return .default
}

I have the following extension methods:

    public static bool IsIn<T>(this T keyObject, params T[] collection)
    {
        return collection.Contains(keyObject);
    }

    public static bool IsIn<T>(this T keyObject, IEnumerable<T> collection)
    {
        return collection.Contains(keyObject);
    }

    public static bool IsNotIn<T>(this T keyObject, params T[] collection)
    {
        return keyObject.IsIn(collection) == false;
    }

    public static bool IsNotIn<T>(this T keyObject, IEnumerable<T> collection)
    {
        return keyObject.IsIn(collection) == false;
    }

Usage:

var inclusionList = new List<string> { "inclusion1", "inclusion2" };
var query = myEntities.MyEntity
                     .Select(e => e.Name)
                     .Where(e => e.IsIn(inclusionList));

var exceptionList = new List<string> { "exception1", "exception2" };
var query = myEntities.MyEntity
                     .Select(e => e.Name)
                     .Where(e => e.IsNotIn(exceptionList));

Very useful as well when passing values directly:

var query = myEntities.MyEntity
                     .Select(e => e.Name)
                     .Where(e => e.IsIn("inclusion1", "inclusion2"));

var query = myEntities.MyEntity
                     .Select(e => e.Name)
                     .Where(e => e.IsNotIn("exception1", "exception2"));

if you have a list a and then following statements

list<int>::iterator it; // declare an iterator
    list<int>::const_iterator cit; // declare an const iterator 
    it=a.begin();
    cit=a.begin();

you can change the contents of the element in the list using “it” but not “cit”, that is you can use “cit” for reading the contents not for updating the elements.

*it=*it+1;//returns no error
    *cit=*cit+1;//this will return error

Update (2018-01-06): This answer is obsolete. Modern versions of PyCharm provide Paths via Settings ? Project Interpreter ? ? ? Show All ? Show paths button.

PyCharm Professional Edition has the Paths tab in Python Interpreters settings, but Community Edition apparently doesn't have it.

As a workaround, you can create a symlink for your imported library under your project's root.

For example:

myproject
    mypackage
        __init__.py
    third_party -> /some/other/directory/third_party

Since this question was asked in 2012 and we have come a long way with browser support for flexboxes, I felt as though this answer was obligatory.

If the display of your parent container is flex, then yes, margin: auto auto (also known as margin: auto) will work to center it both horizontally and vertically, regardless if it is an inline or block element.

#parent {
    width: 50vw;
    height: 50vh;
    background-color: gray;
    display: flex;
}
#child {
    margin: auto auto;
}

<div id="parent">
    <div id="child">hello world</div>
</div>

Note that the width/height do not have to be specified absolutely, as in this example jfiddle which uses sizing relative to the viewport.

Although browser support for flexboxes is at an all-time high at time of posting, many browsers still do not support it or require vendor prefixes. Refer to http://caniuse.com/flexbox for updated browser support information.

Update

Since this answer received a bit of attention, I would also like to point out that you don't need to specify margin at all if you're using display: flex and would like to center all of the elements in the container:

#parent {
    width: 50vw;
    height: 50vh;
    background-color: gray;
    display: flex;
    align-items: center; /* vertical */
    justify-content: center; /* horizontal */
}

<div id="parent">
    <div>hello world</div>
</div>

You can try something like this:

strncpy(new_str, str1, strlen(str1));
strcat(new_str, str2);

More info on strncpy: http://www.cplusplus.com/reference/clibrary/cstring/strncpy/

BEGIN 
DECLARE @totaldays INT; 
DECLARE @weekenddays INT;

SET @totaldays = DATEDIFF(DAY, @startDate, @endDate) 
SET @weekenddays = ((DATEDIFF(WEEK, @startDate, @endDate) * 2) + -- get the number of weekend days in between
                       CASE WHEN DATEPART(WEEKDAY, @startDate) = 1 THEN 1 ELSE 0 END + -- if selection was Sunday, won't add to weekends
                       CASE WHEN DATEPART(WEEKDAY, @endDate) = 6 THEN 1 ELSE 0 END)  -- if selection was Saturday, won't add to weekends

Return (@totaldays - @weekenddays)

END

This is on SQL Server 2014

You can use base_path() to get the base of your application - and then just add your public folder to that:

$path = base_path().'/public';
return File::put($path , $data)

Note: Be very careful about allowing people to upload files into your root of public_html. If they upload their own index.php file, they will take over your site.

Well, you can do

DataTable data = (DataTable)(dgvMyMembers.DataSource);

and then use

data.Columns.Remove(...);

I think it's the fastest way. This will modify data source table, if you don't want it, then copy of table is reqired. Also be aware that DataGridView.DataSource is not necessarily of DataTable type.

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

Had the same issue but mine was working for weeks before this. Realised I had changed my password on the server.

Remember to update your password if you've got the option selected 'Run whether user is logged on or not'

You could try something like this:

SELECT ...
FROM (
    SELECT f1,f2,f3 FROM table1
    UNION
    SELECT f1,f2,f3 FROM table2
)
WHERE ...

You have to add the selector parameter, otherwise the event is directly bound instead of delegated, which only works if the element already exists (so it doesn't work for dynamically loaded content).

See http://api.jquery.com/on/#direct-and-delegated-events

Change your code to

$(document.body).on('click', '.update' ,function(){

The jQuery set receives the event then delegates it to elements matching the selector given as argument. This means that contrary to when using live, the jQuery set elements must exist when you execute the code.

As this answers receives a lot of attention, here are two supplementary advises :

1) When it's possible, try to bind the event listener to the most precise element, to avoid useless event handling.

That is, if you're adding an element of class b to an existing element of id a, then don't use

$(document.body).on('click', '#a .b', function(){

but use

$('#a').on('click', '.b', function(){

2) Be careful, when you add an element with an id, to ensure you're not adding it twice. Not only is it "illegal" in HTML to have two elements with the same id but it breaks a lot of things. For example a selector "#c" would retrieve only one element with this id.

The downfall of ArrayList and LinkedList is that when iterating through them, depending on the search algorithm, the time it takes to find an item grows with the size of the list.

The beauty of hashing is that although you sacrifice some extra time searching for the element, the time taken does not grow with the size of the map. This is because the HashMap finds information by converting the element you are searching for, directly into the index, so it can make the jump.

Long story short... LinkedList: Consumes a little more memory than ArrayList, low cost for insertions(add & remove) ArrayList: Consumes low memory, but similar to LinkedList, and takes extra time to search when large. HashMap: Can perform a jump to the value, making the search time constant for large maps. Consumes more memory and takes longer to find the value than small lists.

Another hack for achieving the same effect is to utilize multiple background images, a feature that is supported in IE9+, newish Firefox, and most WebKit-based browsers: http://caniuse.com/#feat=multibackgrounds

There are also some options for using multiple backgrounds in IE6-8: http://www.beyondhyper.com/css3-multiple-backgrounds-in-non-supportive-browsers/

For example, suppose you want a 5px-wide left border that is a linear gradient from blue to white. Create the gradient as an image and export to a PNG. List any other CSS backgrounds after the one for the left border gradient:

#theBox {
    background:
        url(/images/theBox-leftBorderGradient.png) left no-repeat,
        ...;
}

You can adapt this technique to top, right, and bottom border gradients by changing the background position part of the background shorthand property.

Here is a jsFiddle for the given example: http://jsfiddle.net/jLnDt/

You need a click listener which calls addActivityItem if less than 2 options exist:

var activities = document.getElementById("activitySelector");

activities.addEventListener("click", function() {
    var options = activities.querySelectorAll("option");
    var count = options.length;
    if(typeof(count) === "undefined" || count < 2)
    {
        addActivityItem();
    }
});

activities.addEventListener("change", function() {
    if(activities.value == "addNew")
    {
        addActivityItem();
    }
});

function addActivityItem() {
    // ... Code to add item here
}

A live demo is here on JSfiddle.

A very simple solution is put the below code in your .htaccess. I had the same issue and it solve my problem.

<IfModule mod_alias.c>
    RedirectMatch 403 favicon.ico

Set return type to Void instead of void and return null

// Modify existing method
public static Void displayInt(Integer i) {
    System.out.println(i);
    return null;
}

OR

// Or use Lambda
myForEach(theList, i -> {System.out.println(i);return null;});

You need to add a reference to System.Configuration and then use:

System.Configuration.ConfigurationManager.
    ConnectionStrings["connectionStringName"].ConnectionString;

Let's have a simple one-character string 'š' and encode it into a sequence of bytes:

>>> 'š'.encode('utf-8')
b'\xc5\xa1'

For the purpose of this example let's display the sequence of bytes in its binary form:

>>> bin(int(b'\xc5\xa1'.hex(), 16))
'0b1100010110100001'

Now it is generally not possible to decode the information back without knowing how it was encoded. Only if you know that the utf-8 text encoding was used, you can follow the algorithm for decoding utf-8 and acquire the original string:

11000101 10100001
   ^^^^^   ^^^^^^
   00101   100001

You can display the binary number 101100001 back as a string:

>>> chr(int('101100001', 2))
'š'

You can also use the filter function from the dplyr package which returns rows with matching conditions.

> library(dplyr)

> nrow(filter(aaa, sex == 1 & group1 == 2))
[1] 3
> nrow(filter(aaa, sex == 1 & group2 == "A"))
[1] 2

It works fine : http://codepad.org/5KgO0b1G, your aSourceDictionary variable may have other datatype than dict

aSourceDictionary = { 'abc' : [1,2,3] , 'ccd' : [4,5] }
aTargetDictionary = {}
for aKey in aSourceDictionary:
        aTargetDictionary[aKey] = []
        aTargetDictionary[aKey].extend(aSourceDictionary[aKey])
print aTargetDictionary

Maybe you're not doing it as root?

Try sudo nginx -s reload, if it still doesn't work, you might want to try sudo pkill -HUP nginx.

If you have a manifest file which lists all the files that were installed with make install you can run this command which I have from another answer:

cat install_manifest.txt | xargs echo rm | sh

If you have sudo make install you will need to add a sudo to your uninstall:

cat install_manifest.txt | xargs echo sudo rm | sh

A jQuery solution would be something like:

$(function () {
    $('input').blur();
});

I have write down some code for other question which is similar to this one, but that question got duplicated so i can't answer there so i am just putting my code here if someone looking for same requirement.

It's not fully working code, you need to make some minor changes to get it worked.

Here is the code:

I've used @Graeme idea of using spannable text.

String colorfulText = "colorfulText";       
    Spannable span = new SpannableString(colorfulText);             

    for ( int i = 0, len = colorfulText.length(); i < len; i++ ){
        span.setSpan(new ForegroundColorSpan(getRandomColor()), i, i+1,Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);                     
    }   

    ((TextView)findViewById(R.id.txtSplashscreenCopywrite)).setText(span);

Random Color Method:

  private int getRandomColor(){
        Random rnd = new Random();
        return Color.argb(255, rnd.nextInt(256), rnd.nextInt(256), rnd.nextInt(256));
    }

Django has method_decorator which is a decorator that turns any decorator into a method decorator, you can see how it's implemented in django.utils.decorators:

https://github.com/django/django/blob/50cf183d219face91822c75fa0a15fe2fe3cb32d/django/utils/decorators.py#L53

https://docs.djangoproject.com/en/3.0/topics/class-based-views/intro/#decorating-the-class

As others have said, Stopwatch is a good class to use here. You can wrap it in a helpful method:

public static TimeSpan Time(Action action)
{
    Stopwatch stopwatch = Stopwatch.StartNew();
    action();
    stopwatch.Stop();
    return stopwatch.Elapsed;
}

(Note the use of Stopwatch.StartNew(). I prefer this to creating a Stopwatch and then calling Start() in terms of simplicity.) Obviously this incurs the hit of invoking a delegate, but in the vast majority of cases that won't be relevant. You'd then write:

TimeSpan time = StopwatchUtil.Time(() =>
{
    // Do some work
});

You could even make an ITimer interface for this, with implementations of StopwatchTimer, CpuTimer etc where available.

i also recommend thinking this thru and then choosing to store images in your file system rather than the DB .. see here: Storing Images in DB - Yea or Nay?

Not sure how to explain this but I ran into something similar today. Not being able to set .user:first-of-type{} while .user:last-of-type{} worked fine. This was fixed after I wrapped them inside a div without any class or styling:

https://codepen.io/adrianTNT/pen/WgEpbE

<style>
.user{
  display:block;
  background-color:#FFCC00;
}

.user:first-of-type{
  background-color:#FF0000;
}
</style>

<p>Not working while this P additional tag exists</p>

<p class="user">A</p>
<p class="user">B</p>
<p class="user">C</p>

<p>Working while inside a div:</p>

<div>
<p class="user">A</p>
<p class="user">B</p>
<p class="user">C</p>
</div>

You can use System.setProperty("java.net.preferIPv4Stack" , "true");

This is equivalent to passing it in the command line via -Djava.net.preferIPv4Stack=true

What you are trying to do is an extension of string slicing in Python:

Say all strings are of length 10, last char to be removed:

>>> st[:9]
'abcdefghi'

To remove last N characters:

>>> N = 3
>>> st[:-N]
'abcdefg'

Read file contents into a variable:

for /f "delims=" %%x in (version.txt) do set Build=%%x

or

set /p Build=<version.txt

Both will act the same with only a single line in the file, for more lines the for variant will put the last line into the variable, while set /p will use the first.

Using the variable – just like any other environment variable – it is one, after all:

%Build%

So to check for existence:

if exist \\fileserver\myapp\releasedocs\%Build%.doc ...

Although it may well be that no UNC paths are allowed there. Can't test this right now but keep this in mind.

Another yet simple solution is to paste these line into the build.gradle file

dependencies {

    //import of gridlayout
    compile 'com.android.support:gridlayout-v7:19.0.0'
    compile 'com.android.support:appcompat-v7:+'
}

There is no completely portable solution.

Question 19.1 of the comp.lang.c FAQ covers this in some depth, with solutions for Windows, Unix-like systems, and even MS-DOS and VMS.

A quick and incomplete summary:

• You can use the curses library; call cbreak() followed by getch() (not to be confused with the Windows-specific getch()function). Note that curses generally takes control of the terminal, so this is likely to be overkill.
• You might be able to use ioctl() to manipulate the terminal settings.
• On POSIX-compliant systems, tcgetattr() and tcsetattr() may be a better solution.
• On Unix, you can use system() to invoke the stty command.
• On MS-DOS, you can use getch() or getche().
• On VMS (now called OpenVMS), the Screen Management (SMG$) routines might do the trick.

All these C solutions should work equally well in C++; I don't know of any C++-specific solution.

typeof(MyType).GetField("fieldName", BindingFlags.NonPublic | BindingFlags.Instance)

del list[:] 

Will delete the values of that list variable

del list

Will delete the variable itself from memory

You can redirect the regular stdin through unit 3 to keep the get it inside the pipeline:

{ cat notify-finished | while read line; do
    read -u 3 input
    echo "$input"
done; } 3<&0

BTW, if you really are using cat this way, replace it with a redirect and things become even easier:

while read line; do
    read -u 3 input
    echo "$input"
done 3<&0 <notify-finished

Or, you can swap stdin and unit 3 in that version -- read the file with unit 3, and just leave stdin alone:

while read line <&3; do
    # read & use stdin normally inside the loop
    read input
    echo "$input"
done 3<notify-finished

if not %1 == "" (

must be

if not "%1" == "" (

If an argument isn't given, it's completely empty, not even "" (which represents an empty string in most programming languages). So we use the surrounding quotes to detect an empty argument.

I have a rooted Samsung Galaxy Trend Plus (GT-S7580).

Running 'adb root' gives me the same 'adbd cannot run as root in production builds' error.

For devices that have Developer Options -> Root access, choose "ADB only" to provide adb root access to the device (as suggested by NgaNguyenDuy).

Then try to run the command as per the solution at Launch a script as root through ADB. In my case, I just wanted to run the 'netcfg rndis0 dhcp' command, and I did it this way:

adb shell "su -c netcfg rndis0 dhcp"

Please check whether you are making any mistakes while running it this way.

If it still does not work, check whether you rooted the device correctly. If still no luck, try installing a custom ROM such as Cyanogen Mod in order for 'adb root' to work.

LINQ Any() would do the job:

bool contains = myList.Any(s => s.Contains(pattern));

Some more details in relation with the response from Cody Gray. As it took me some time to digest it I though it might be usefull to others.

First, some definitions:

1. There are TypeNames, which are string representations of the type of an object, interface, etc. For example, Bar is a TypeName in Public Class Bar, or in Dim Foo as Bar. TypeNames could be seen as "labels" used in the code to tell the compiler which type definition to look for in a dictionary where all available types would be described.
2. There are System.Type objects which contain a value. This value indicates a type; just like a String would take some text or an Int would take a number, except we are storing types instead of text or numbers. Type objects contain the type definitions, as well as its corresponding TypeName.

Second, the theory:

1. Foo.GetType() returns a Type object which contains the type for the variable Foo. In other words, it tells you what Foo is an instance of.
2. GetType(Bar) returns a Type object which contains the type for the TypeName Bar.

3. In some instances, the type an object has been Cast to is different from the type an object was first instantiated from. In the following example, MyObj is an Integer cast into an Object:

   Dim MyVal As Integer = 42 Dim MyObj As Object = CType(MyVal, Object)

So, is MyObj of type Object or of type Integer? MyObj.GetType() will tell you it is an Integer.

4. But here comes the Type Of Foo Is Bar feature, which allows you to ascertain a variable Foo is compatible with a TypeName Bar. Type Of MyObj Is Integer and Type Of MyObj Is Object will both return True. For most cases, TypeOf will indicate a variable is compatible with a TypeName if the variable is of that Type or a Type that derives from it. More info here: https://docs.microsoft.com/en-us/dotnet/visual-basic/language-reference/operators/typeof-operator#remarks

The test below illustrate quite well the behaviour and usage of each of the mentionned keywords and properties.

Public Sub TestMethod1()

    Dim MyValInt As Integer = 42
    Dim MyValDble As Double = CType(MyValInt, Double)
    Dim MyObj As Object = CType(MyValDble, Object)

    Debug.Print(MyValInt.GetType.ToString) 'Returns System.Int32
    Debug.Print(MyValDble.GetType.ToString) 'Returns System.Double
    Debug.Print(MyObj.GetType.ToString) 'Returns System.Double

    Debug.Print(MyValInt.GetType.GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(MyValDble.GetType.GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(MyObj.GetType.GetType.ToString) 'Returns System.RuntimeType

    Debug.Print(GetType(Integer).GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(GetType(Double).GetType.ToString) 'Returns System.RuntimeType
    Debug.Print(GetType(Object).GetType.ToString) 'Returns System.RuntimeType

    Debug.Print(MyValInt.GetType = GetType(Integer)) '# Returns True
    Debug.Print(MyValInt.GetType = GetType(Double)) 'Returns False
    Debug.Print(MyValInt.GetType = GetType(Object)) 'Returns False

    Debug.Print(MyValDble.GetType = GetType(Integer)) 'Returns False
    Debug.Print(MyValDble.GetType = GetType(Double)) '# Returns True
    Debug.Print(MyValDble.GetType = GetType(Object)) 'Returns False

    Debug.Print(MyObj.GetType = GetType(Integer)) 'Returns False
    Debug.Print(MyObj.GetType = GetType(Double)) '# Returns True
    Debug.Print(MyObj.GetType = GetType(Object)) 'Returns False

    Debug.Print(TypeOf MyObj Is Integer) 'Returns False
    Debug.Print(TypeOf MyObj Is Double) '# Returns True
    Debug.Print(TypeOf MyObj Is Object) '# Returns True


End Sub

EDIT

You can also use Information.TypeName(Object) to get the TypeName of a given object. For example,

Dim Foo as Bar
Dim Result as String
Result = TypeName(Foo)
Debug.Print(Result) 'Will display "Bar"

I recommend you just use rubyinstaller

It is recommended by the official Ruby page - see https://www.ruby-lang.org/en/downloads/

Ways of Installing Ruby

We have several tools on each major platform to install Ruby:

• On Linux/UNIX, you can use the package management system of your distribution or third-party tools (rbenv and RVM).
• On OS X machines, you can use third-party tools (rbenv and RVM).
• On Windows machines, you can use RubyInstaller.

I have tried all the solutions above, but the following solved my problem

chcon -R -t httpd_sys_rw_content_t your_file_directory

Easiest way would probably be with jQuery, as follows:

$(document).ready(function(){
  $("#_1234").attr("checked","checked");
})

This adds a new attribute "checked" (which in HTML does not need a value). Just remember to include the jQuery library:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>

Run the code either in onload event, either just before you close body tag. You try to find an element wich is not there at the moment you do it.

It turns out that you can create 32-bit ODBC connections using C:\Windows\SysWOW64\odbcad32.exe. My solution was to create the 32-bit ODBC connection as a System DSN. This still didn't allow me to connect to it since .NET couldn't look it up. After significant and fruitless searching to find how to get the OdbcConnection class to look for the DSN in the right place, I stumbled upon a web site that suggested modifying the registry to solve a different problem.

I ended up creating the ODBC connection directly under HKLM\Software\ODBC. I looked in the SysWOW6432 key to find the parameters that were set up using the 32-bit version of the ODBC administration tool and recreated this in the standard location. I didn't add an entry for the driver, however, as that was not installed by the standard installer for the app either.

After creating the entry (by hand), I fired up my windows service and everything was happy.

Click on Deployment Assembly ( right above Java Build Path that you show as active ) and make sure that you see json-lib-2.4-jdk15.jar there.

Usually, you should add it to your build path and export it from your project. Once it's exported you will see the WTP warning that it's not a part of the deployment. Choose the Quick Fix option and add it to your deployment path.

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

Microsoft SQL Server for instance, Schemas refer to a single user and is another level of a container in the order of indicating the server, database, schema, tables, and objects.

For example, when you are intending to update dbo.table_a and the syntax isn't full qualified such as UPDATE table.a the DBMS can't decide to use the intended table. Essentially by default the DBMS will utilize myuser.table_a

How you can reproduce this cryptic error on the Ubuntu terminal:

Put this in a file called Main.java:

public Main{
    public static void main(String[] args){
        System.out.println("ok");
    }
}

Then compile it like this:

user@defiant /home/user $ javac Main
error: Class names, 'Main', are only accepted if 
annotation processing is explicitly requested
1 error

It's because you didn't specify .java at the end of Main.

Do it like this, and it works:

user@defiant /home/user $ javac Main.java
user@defiant /home/user $

Slap your forehead now and grumble that the error message is so cryptic.

Try to change where Member class

public function users() {
    return $this->hasOne('User');
} 

return $this->belongsTo('User');

How to use a socks proxy?

Set up a SSH tunnel to a server somewhere:

ssh -D $PORT $USER@$SERVER

Linux (bash):

export MAVEN_OPTS="-DsocksProxyHost=127.0.0.1 -DsocksProxyPort=$PORT"

Windows:

set MAVEN_OPTS="-DsocksProxyHost=127.0.0.1 -DsocksProxyPort=$PORT"

Your function is just fine but isn't working because you put the () after the last }. If you move the () to the top just next to new List<string>() the error stops.

Sample below:

List<string> optionList = new List<string>()
{
    "AdditionalCardPersonAdressType","AutomaticRaiseCreditLimit","CardDeliveryTimeWeekDay"
};

The answer is "mostly".

We've hit a problem using it where the EF generates code that uses the CROSS and OUTER APPLY operators. This link shows that MS knows its a problem with SQL Server previous to 2005 however, they forget to mention that these operators are not supported by Oracle either.

VonC mentioned in his answer how to remote debug from Eclipse.

I would like to add that the JAVA_OPTS settings are already in run.conf.bat. You just have to uncomment them:

in JBOSS_HOME\bin\run.conf.bat on Windows:

rem # Sample JPDA settings for remote socket debugging
set "JAVA_OPTS=%JAVA_OPTS% -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"

The Linux version is similar and is located at JBOSS_HOME/bin/run.conf

use below code

server.mappath() in asp.net

application.startuppath in c# windows application

A more current take on the situation. During 2018, the C++ extension added another option to the configuration compilerPath of the c_cpp_properties.json file;

compilerPath (optional) The absolute path to the compiler you use to build your project. The extension will query the compiler to determine the system include paths and default defines to use for IntelliSense.

If used, the includePath would not be needed since the IntelliSense will use the compiler to figure out the system include paths.

Originally,

How and where can I add include paths in the configurations below?

The list is a string array, hence adding an include path would look something like;

"configurations": [
    {
        "name": "Mac",
        "includePath": ["/usr/local/include",
            "/path/to/additional/includes",
            "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include"
        ]
    }
]

Source; cpptools blog 31 March 2016.

The linked source has a gif showing the format for the Win32 configuration, but the same applies to the others.

The above sample includes the SDK (OSX 10.11) path if Xcode is installed.

Note I find it can take a while to update once the include path has been changed.

Further documentation (from Microsoft) on the C++ language support in VSCode can be found here.

For the sake of preservation (from the discussion), the following are basic snippets for the contents of the tasks.json file to compile and execute either a C++ file, or a C file. They allow for spaces in the file name (requires escaping the additional quotes in the json using \"). The shell is used as the runner, thus allowing the compilation (clang...) and the execution (&& ./a.out) of the program. It also assumes that the tasks.json "lives" in the local workspace (under the directory .vscode). Further task.json details, such as supported variables etc. can be found here.

Ubuntu 15.10, Kernel 4.2.0, x86-64, GCC 5.2.1 example

Enough standards, let's look at an implementation :-)

Local variable

Standards: undefined behavior.

Implementation: the program allocates stack space, and never moves anything to that address, so whatever was there previously is used.

#include <stdio.h>
int main() {
    int i;
    printf("%d\n", i);
}

compile with:

gcc -O0 -std=c99 a.c

outputs:

0

and decompiles with:

objdump -dr a.out

to:

0000000000400536 <main>:
  400536:       55                      push   %rbp
  400537:       48 89 e5                mov    %rsp,%rbp
  40053a:       48 83 ec 10             sub    $0x10,%rsp
  40053e:       8b 45 fc                mov    -0x4(%rbp),%eax
  400541:       89 c6                   mov    %eax,%esi
  400543:       bf e4 05 40 00          mov    $0x4005e4,%edi
  400548:       b8 00 00 00 00          mov    $0x0,%eax
  40054d:       e8 be fe ff ff          callq  400410 <printf@plt>
  400552:       b8 00 00 00 00          mov    $0x0,%eax
  400557:       c9                      leaveq
  400558:       c3                      retq

From our knowledge of x86-64 calling conventions:

• %rdi is the first printf argument, thus the string "%d\n" at address 0x4005e4

• %rsi is the second printf argument, thus i.

  It comes from -0x4(%rbp), which is the first 4-byte local variable.

  At this point, rbp is in the first page of the stack has been allocated by the kernel, so to understand that value we would to look into the kernel code and find out what it sets that to.

  TODO does the kernel set that memory to something before reusing it for other processes when a process dies? If not, the new process would be able to read the memory of other finished programs, leaking data. See: Are uninitialized values ever a security risk?

We can then also play with our own stack modifications and write fun things like:

#include <assert.h>

int f() {
    int i = 13;
    return i;
}

int g() {
    int i;
    return i;
}

int main() {
    f();
    assert(g() == 13);
}

Local variable in -O3

#include <stdio.h>

  40055f:       00

# 601044 <i> says that i is at address 0x601044 and:

readelf -SW a.out

contains:

[25] .bss              NOBITS          0000000000601040 001040 000008 00  WA  0   0  4

which says 0x601044 is right in the middle of the .bss section, which starts at 0x601040 and is 8 bytes long.

The ELF standard then guarantees that the section named .bss is completely filled with of zeros:

.bss This section holds uninitialized data that contribute to the program’s memory image. By definition, the system initializes the data with zeros when the program begins to run. The section occu- pies no file space, as indicated by the section type, SHT_NOBITS.

Furthermore, the type SHT_NOBITS is efficient and occupies no space on the executable file:

sh_size This member gives the section’s size in bytes. Unless the sec- tion type is SHT_NOBITS , the section occupies sh_size bytes in the file. A section of type SHT_NOBITS may have a non-zero size, but it occupies no space in the file.

Then it is up to the Linux kernel to zero out that memory region when loading the program into memory when it gets started.

I also got the error you mention:

CMake Error: CMake can not determine linker language for target:helloworld
CMake Error: Cannot determine link language for target "helloworld".

In my case this was due to having C++ files with the .cc extension.

If CMake is unable to determine the language of the code correctly you can use the following:

set_target_properties(hello PROPERTIES LINKER_LANGUAGE CXX)

The accepted answer that suggests appending the language to the project() statement simply adds more strict checking for what language is used (according to the documentation), but it wasn't helpful to me:

Optionally you can specify which languages your project supports. Example languages are CXX (i.e. C++), C, Fortran, etc. By default C and CXX are enabled. E.g. if you do not have a C++ compiler, you can disable the check for it by explicitly listing the languages you want to support, e.g. C. By using the special language "NONE" all checks for any language can be disabled. If a variable exists called CMAKE_PROJECT__INCLUDE_FILE, the file pointed to by that variable will be included as the last step of the project command.

You are right that CSS positioning is the way to go. Here's a quick run down:

position: relative will layout an element relative to itself. In other words, the elements is laid out in normal flow, then it is removed from normal flow and offset by whatever values you have specified (top, right, bottom, left). It's important to note that because it's removed from flow, other elements around it will not shift with it (use negative margins instead if you want this behaviour).

However, you're most likely interested in position: absolute which will position an element relative to a container. By default, the container is the browser window, but if a parent element either has position: relative or position: absolute set on it, then it will act as the parent for positioning coordinates for its children.

To demonstrate:

#container {_x000D_
  position: relative;_x000D_
  border: 1px solid red;_x000D_
  height: 100px;_x000D_
}_x000D_
_x000D_
#box {_x000D_
  position: absolute;_x000D_
  top: 50px;_x000D_
  left: 20px;_x000D_
}

<div id="container">_x000D_
  <div id="box">absolute</div>_x000D_
</div>

In that example, the top left corner of #box would be 100px down and 50px left of the top left corner of #container. If #container did not have position: relative set, the coordinates of #box would be relative to the top left corner of the browser view port.

int numLines = 0;

Container( height: numLines < 7 ? 148 * WidgetsConstant.height : numLines * WidgetsConstant.height * 24, child: TextFormField( controller: _bodyText, maxLines: numLines < 7 ? 148 : numLines, keyboardType: TextInputType.multiline, textInputAction: TextInputAction.newline,
onChanged: (String value) { setState(() { numLines = '\n'.allMatches(value).length + 1; }); }, ), ),

After reading some issues reported on the GitHub repository, I found the solution.

In order to update the angular-cli package installed globally in your system, you need to run:

npm uninstall -g @angular-cli
npm install -g @angular/cli@latest

Depending on your system, you may need to prefix the above commands with sudo.

Also, most likely you want to also update your local project version, because inside your project directory it will be selected with higher priority than the global one:

rm -rf node_modules
npm uninstall --save-dev @angular-cli
npm install --save-dev @angular/cli@latest
npm install

thanks grizzm0 for pointing this out on GitHub.

After updating your CLI, you probably want to update your Angular version too.

Note: if you are updating to Angular CLI 6+ from an older version, you might need to read this.

Edit: In addition, if you were still on a 1.x version of the cli, you need to convert your angular-cli.json to angular.json, which you can do with the following command:

ng update @angular/cli --from=1.7.4 --migrate-only

(check this for more details).

I had this problem, but in my case it was because of a delayed loading of the module I was trying to debug. I had a DLL linked to my main project and the DLL is what I was debugging. The DLL was only called when certain functions in the main application were called so VS2010 didn't load the module until those functions were called.

When I started the project I recieved this message, but by the time I executed the function the debugger had loaded the module and the related debugging information.

check the error with mysqli_error() function

probably your query has some faults.

Use the re.escape() function for this:

4.2.3 re Module Contents

escape(string)

Return string with all non-alphanumerics backslashed; this is useful if you want to match an arbitrary literal string that may have regular expression metacharacters in it.

A simplistic example, search any occurence of the provided string optionally followed by 's', and return the match object.

def simplistic_plural(word, text):
    word_or_plural = re.escape(word) + 's?'
    return re.match(word_or_plural, text)

You can use Chr(13). Then just wrap the whole thing in Chr(34). Chr(34) is double quotes.

• VB.Net Example:
• TheContactInfo = ""
• TheContactInfo = Trim(TheEmail) & chr(13)
• TheContactInfo = TheContactInfo & Trim(ThePhone) & chr(13)
• TheContactInfo = Chr(34) & TheContactInfo & Chr(34)

Try below code :

 public static void main(String[] args) throws Exception{
     List<String> l = new ArrayList<String>();
     l.add("abc");
     l.add("xyz");
     l.add("test");
     l.add("test123");
     System.out.println(l);
     List<String> dl = new ArrayList<String>();
    for (int i = 0; i < l.size(); i++) {
         String a = l.get(i);
         System.out.println(a); 
         if(a.equals("test")){
             dl.add(a);
         }
    }
    l.removeAll(dl);
     System.out.println(l); 
}

your output :

 [abc, xyz, test, test123]
abc
xyz
test
test123
[abc, xyz, test123]

I'm interpreting your question to be about getting row numbers.

• You can try as.numeric(rownames(df)) if you haven't set the rownames. Otherwise use a sequence of 1:nrow(df).
• The which() function converts a TRUE/FALSE row index into row numbers.

I got this issue when I used an ajax call to retrieve data from the database. When the controller returned the array it converted it to a boolean. The problem was that I had "invalid characters" like ú (u with accent).

In this code you access to root directory project:

 string _filePath = Path.GetDirectoryName(System.AppDomain.CurrentDomain.BaseDirectory);

then:

StreamReader r = new StreamReader(_filePath + "/cities2.json"))

Go to Control Panel\User Accounts\Credential Manager and select Windows Credential then remove account of git.

you can use this one instead.

System.Environment.CurrentDirectory

This requires changes to the frontend JS and the headers sent from the backend.

Frontend

Remove "mode":"no-cors" in the fetch options.

fetch(
  "http://example.com/api/docs", 
  {
    // mode: "no-cors",
    method: "GET"
  }
)
  .then(response => response.text())
  .then(data => console.log(data))

Backend

When your server responds to the request, include the CORS headers specifying the origin from where the request is coming. If you don't care about the origin, specify the * wildcard.

The raw response should include a header like this.

Access-Control-Allow-Origin: *

<iframe> elements have a load event for that.

How you listen to that event is up to you, but generally the best way is to:

1) create your iframe programatically

It makes sure your load listener is always called by attaching it before the iframe starts loading.

<script>
var iframe = document.createElement('iframe');
iframe.onload = function() { alert('myframe is loaded'); }; // before setting 'src'
iframe.src = '...'; 
document.body.appendChild(iframe); // add it to wherever you need it in the document
</script>

2) inline javascript, is another way that you can use inside your HTML markup.

<script>
function onMyFrameLoad() {
  alert('myframe is loaded');
};
</script>

<iframe id="myframe" src="..." onload="onMyFrameLoad(this)"></iframe>

3) You may also attach the event listener after the element, inside a <script> tag, but keep in mind that in this case, there is a slight chance that the iframe is already loaded by the time you get to adding your listener. Therefore it's possible that it will not be called (e.g. if the iframe is very very fast, or coming from cache).

<iframe id="myframe" src="..."></iframe>

<script>
document.getElementById('myframe').onload = function() {
  alert('myframe is loaded');
};
</script>

Also see my other answer about which elements can also fire this type of load event

The first part is for setting cron job and the next part to call your function.

On a Mac (pdftex) I managed to include a png file simply with \includegraphics[width=1.2\textwidth]{filename.png}. But in order for that to work I had to comment out the following 2 packages:

%\usepackage[dvips]{epsfig}

%\usepackage[dvips]{graphicx}

...and simply use package graphicx:

\usepackage{graphicx}

It seems [dvips] is problematic when used with pdftex.

@Dinh Nhat, your setter method looks wrong because you put a primitive type there again and it should be:

public void setClient_os_id(Integer clientOsId) {
client_os_id = clientOsId;
}

Probably invalid syntax in your onChange event, I avoid using like this (within the html) as I think it is messy and it is hard enough keeping JavaScript tidy at the best of times.

I would rather register the event on the document ready event in javascript. You will also definitely want to use keyup event too if you want the validation as the user is typing:

$(document).ready(function () {
   $("#txtConfirmPassword").keyup(checkPasswordMatch);
});

Here is a working example

Personally I would prefer to do the check when either password field changes, that way if they re-type the original password then you still get the same validation check:

$(document).ready(function () {
   $("#txtNewPassword, #txtConfirmPassword").keyup(checkPasswordMatch);
});

Here is a working example

The basic colours are RGB not RYB. Yes most of the softwares use the traditional RGB which can be used to mix together to form any other color i.e. RGB are the fundamental colours (as defined in Physics & Chemistry texts).

The printer user CMYK (cyan, magenta, yellow, and black) coloring as said by @jcomeau_ictx. You can view the following article to know about RGB vs CMYK: RGB Vs CMYK

A bit more information from the extract about them:

Red, Green, and Blue are "additive colors". If we combine red, green and blue light you will get white light. This is the principal behind the T.V. set in your living room and the monitor you are staring at now. Additive color, or RGB mode, is optimized for display on computer monitors and peripherals, most notably scanning devices.

Cyan, Magenta and Yellow are "subtractive colors". If we print cyan, magenta and yellow inks on white paper, they absorb the light shining on the page. Since our eyes receive no reflected light from the paper, we perceive black... in a perfect world! The printing world operates in subtractive color, or CMYK mode.

I was getting the same error when I tried to run "ng serve" after that I saw some suggetions one of the techie told me to update my npm.I did that as well then I got this screen after entering "ng server"

""Versions of @angular/compiler-cli and typescript could not be determined. The most common reason for this is a broken npm install. Please make sure your package.json contains both @angular/compiler-cli and typescript in devDependencies, then delete node_module and package-lock.json(if you have one) and Run npm install again.""

After performing all the actions now its working correctly...and getting message "Compiled Successfully."

You will have the duplicate values for name and price here. And ids are duplicate in the drinks_photos table.There is no way you can avoid them.Also what exactly you want the output ?

You can dump the value in hex using UTL_RAW.CAST_TO_RAW(UTL_RAW.CAST_TO_VARCHAR2()).

SELECT b FROM foo;
-- (BLOB)

SELECT UTL_RAW.CAST_TO_RAW(UTL_RAW.CAST_TO_VARCHAR2(b))
FROM foo;
-- 1F8B080087CDC1520003F348CDC9C9D75128CF2FCA49D1E30200D7BBCDFC0E000000

This is handy because you this is the same format used for inserting into BLOB columns:

CREATE GLOBAL TEMPORARY TABLE foo (
    b BLOB);
INSERT INTO foo VALUES ('1f8b080087cdc1520003f348cdc9c9d75128cf2fca49d1e30200d7bbcdfc0e000000');

DESC foo;
-- Name Null Type 
-- ---- ---- ---- 
-- B        BLOB 

However, at a certain point (2000 bytes?) the corresponding hex string exceeds Oracle’s maximum string length. If you need to handle that case, you’ll have to combine How do I get textual contents from BLOB in Oracle SQL with the documentation for DMBS_LOB.SUBSTR for a more complicated approach that will allow you to see substrings of the BLOB.

You are converting cert into BKS Keystore, why aren't you using .cert directly, from https://developer.android.com/training/articles/security-ssl.html:

CertificateFactory cf = CertificateFactory.getInstance("X.509");
InputStream instream = context.getResources().openRawResource(R.raw.gtux_cert);
Certificate ca;
try {
    ca = cf.generateCertificate(instream);
} finally {
    caInput.close();
}

KeyStore kStore = KeyStore.getInstance(KeyStore.getDefaultType());
kStore.load(null, null);
kStore.setCertificateEntry("ca", ca);

TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm(););
tmf.init(kStore);

SSLContext context = SSLContext.getInstance("TLS");
context.init(null, tmf.getTrustManagers(), null);

okHttpClient.setSslSocketFactory(context.getSocketFactory());

You can simply use:

#contentInfo_new br {display:none;}

You should use the resource folders such as

values-ldpi
values-mdpi
values-hdpi

And write the text size in 'dimensions.xml' file for each range.

And in the java code you can set the text size with

textView.setTextSize(getResources().getDimension(R.dimen.textsize));

Sample dimensions.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="textsize">15sp</dimen>
</resources>

Edit / Update:

If you are using Typescript 3.7 or newer you can now also do:

    const data = change?.after?.data();

    if(!data) {
      console.error('No data here!');
       return null
    }

    const maxLen = 100;
    const msgLen = data.messages.length;
    const charLen = JSON.stringify(data).length;

    const batch = db.batch();

    if (charLen >= 10000 || msgLen >= maxLen) {

      // Always delete at least 1 message
      const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
      data.messages.splice(0, deleteCount);

      const ref = db.collection("chats").doc(change.after.id);

      batch.set(ref, data, { merge: true });

      return batch.commit();
    } else {
      return null;
    }

Original Response

Typescript is saying that change or data is possibly undefined (depending on what onUpdate returns).

So you should wrap it in a null/undefined check:

if(change && change.after && change.after.data){
    const data = change.after.data();

    const maxLen = 100;
    const msgLen = data.messages.length;
    const charLen = JSON.stringify(data).length;

    const batch = db.batch();

    if (charLen >= 10000 || msgLen >= maxLen) {

      // Always delete at least 1 message
      const deleteCount = msgLen - maxLen <= 0 ? 1 : msgLen - maxLen
      data.messages.splice(0, deleteCount);

      const ref = db.collection("chats").doc(change.after.id);

      batch.set(ref, data, { merge: true });

      return batch.commit();
    } else {
      return null;
    }
}

If you are 100% sure that your object is always defined then you can put this:

const data = change.after!.data();

UPDATE: Added a more detailed description of the formset errors.

Form.errors combines all field and non_field_errors. Therefore you can simplify the html to this:

template

    {% load form_tags %}

    {% if form.errors %}
    <div class="alert alert-danger alert-dismissible col-12 mx-1" role="alert">
        <div id="form_errors">
            {% for key, value in form.errors.items %}
                <span class="fieldWrapper">
                    {{ key }}:{{ value }}
                </span>
            {% endfor %}
        </div>
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
    {% endif %}


If you want to generalise it you can create a list_errors.html which you include in every form template. It handles form and formset errors:

    {% if form.errors %}
    <div class="alert alert-danger alert-dismissible col-12 mx-1" role="alert">
        <div id="form_errors">

            {% for key, value in form.errors.items %}
                <span class="fieldWrapper">
                    {{ key }}:{{ value }}
                </span>
            {% endfor %}
        </div>
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
    {% elif formset.total_error_count %}
    <div class="alert alert-danger alert-dismissible col-12 mx-1" role="alert">
        <div id="form_errors">
            {% if formset.non_form_errors %}
                {{ formset.non_form_errors }}
            {% endif %}
            {% for form in formset.forms %}
                {% if form.errors %}
                    Form number {{ forloop.counter }}:
                    <ul class="errorlist">
                    {% for key, error in form.errors.items %}
                        <li>{{form.fields|get_label:key}}
                            <ul class="errorlist">
                                <li>{{error}}</li>
                            </ul>
                        </li>
                    {% endfor %}
                    </ul>
                {% endif %}
            {% endfor %}

        </div>
    </div>

    {% endif %}

form_tags.py

from django import template

register = template.Library()


def get_label(a_dict, key):
    return getattr(a_dict.get(key), 'label', 'No label')


register.filter("get_label", get_label)

One caveat: In contrast to forms Formset.errors does not include non_field_errors.

Timedelta objects have read-only instance attributes .days, .seconds, and .microseconds.

$.fn.outerHtml = function(){
    if (this.length) {
        var div = $('<div style="display:none"></div>');
        var clone =
        $(this[0].cloneNode(false)).html(this.html()).appendTo(div);
        var outer = div.html();
        div.remove();
        return outer;
    }
    else {
        return null;
    }
};

I had the same problem with PHP. I solved it by changing "localhost" to "127.0.0.1" in database connection parameters like someone suggested here: https://serverfault.com/a/444338/62739 . I think it may work for you too, give it a try.

In Java >=8 you could also use the Streaming API:

Optional<String> first = set.stream().findFirst();

(Useful if the Set/List may be empty.)

Also the more concise way is to use their selectors engine. So to disable all form elements in a div or form parent.

$myForm.find(':input:not(:disabled)').prop('disabled',true)

For Python 2.7 and Pandas 0.24.2 and using Psycopg2

Psycopg2 Connection Module

def dbConnect (db_parm, username_parm, host_parm, pw_parm):
    # Parse in connection information
    credentials = {'host': host_parm, 'database': db_parm, 'user': username_parm, 'password': pw_parm}
    conn = psycopg2.connect(**credentials)
    conn.autocommit = True  # auto-commit each entry to the database
    conn.cursor_factory = RealDictCursor
    cur = conn.cursor()
    print ("Connected Successfully to DB: " + str(db_parm) + "@" + str(host_parm))
    return conn, cur

Connect to the database

conn, cur = dbConnect(databaseName, dbUser, dbHost, dbPwd)

Assuming dataframe to be present already as df

output = io.BytesIO() # For Python3 use StringIO
df.to_csv(output, sep='\t', header=True, index=False)
output.seek(0) # Required for rewinding the String object
copy_query = "COPY mem_info FROM STDOUT csv DELIMITER '\t' NULL ''  ESCAPE '\\' HEADER "  # Replace your table name in place of mem_info
cur.copy_expert(copy_query, output)
conn.commit()

Create Bean for Rest Template to auto wiring the Rest Template object.

@SpringBootApplication
public class ChatAppApplication {

    @Bean
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }

    public static void main(String[] args) {
        SpringApplication.run(ChatAppApplication.class, args);
    }

}

Consume the GET/POST API by using RestTemplate - exchange() method. Below is for the post api which is defined in the controller.

@RequestMapping(value = "/postdata",method = RequestMethod.POST)
    public String PostData(){

       return "{\n" +
               "   \"value\":\"4\",\n" +
               "   \"name\":\"David\"\n" +
               "}";
    }

    @RequestMapping(value = "/post")
    public String getPostResponse(){
        HttpHeaders headers=new HttpHeaders();
        headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
        HttpEntity<String> entity=new HttpEntity<String>(headers);
        return restTemplate.exchange("http://localhost:8080/postdata",HttpMethod.POST,entity,String.class).getBody();
    }

Refer this tutorial[1]

To grant a permission:

grant select on schema_name.sequence_name to user_or_role_name;

To check which permissions have been granted

select * from all_tab_privs where TABLE_NAME = 'sequence_name'

Your code seems to be fine, make sure that key you specify really exists in the array or such key has a value in your array eg:

$array = array(4 => 'Hello There');
print_r(array_keys($array));
// or better
print_r($array);

Output:

Array
(
    [0] => 4
)

Now:

$key = 4;
$value = $array[$key];
print $value;

Output:

Hello There

Navigate to your play page:

https://play.google.com/store/apps/details?id=com.yourpackage

Using a standard HTTP GET. Now the following jQuery finds important info for you:

Current Version

$("[itemprop='softwareVersion']").text()

What's new

$(".recent-change").each(function() { all += $(this).text() + "\n"; })

Now that you can extract these information manually, simply make a method in your app that executes this for you.

public static String[] getAppVersionInfo(String playUrl) {
    HtmlCleaner cleaner = new HtmlCleaner();
    CleanerProperties props = cleaner.getProperties();
    props.setAllowHtmlInsideAttributes(true);
    props.setAllowMultiWordAttributes(true);
    props.setRecognizeUnicodeChars(true);
    props.setOmitComments(true);
    try {
        URL url = new URL(playUrl);
        URLConnection conn = url.openConnection();
        TagNode node = cleaner.clean(new InputStreamReader(conn.getInputStream()));
        Object[] new_nodes = node.evaluateXPath("//*[@class='recent-change']");
        Object[] version_nodes = node.evaluateXPath("//*[@itemprop='softwareVersion']");

        String version = "", whatsNew = "";
        for (Object new_node : new_nodes) {
            TagNode info_node = (TagNode) new_node;
            whatsNew += info_node.getAllChildren().get(0).toString().trim()
                    + "\n";
        }
        if (version_nodes.length > 0) {
            TagNode ver = (TagNode) version_nodes[0];
            version = ver.getAllChildren().get(0).toString().trim();
        }
        return new String[]{version, whatsNew};
    } catch (IOException | XPatherException e) {
        e.printStackTrace();
        return null;
    }
}

The {} syntax is deprecated as of PHP 5.3.0. Square brackets are recommended.

Use perl for multicharacter separators:

function join {
   perl -e '$s = shift @ARGV; print join($s, @ARGV);' "$@"; 
}

join ', ' a b c # a, b, c

Or in one line:

perl -le 'print join(shift, @ARGV);' ', ' 1 2 3
1, 2, 3

The number of possible binary search tree with n nodes (elements,items) is

=(2n C n) / (n+1) = ( factorial (2n) / factorial (n) * factorial (2n - n) ) / ( n + 1 ) 

where 'n' is number of nodes  (elements,items ) 

Example :

for 
n=1 BST=1,
n=2 BST 2,
n=3 BST=5,
n=4 BST=14 etc

I set the column widths in the HTML markup like so:

    <thead>
        <tr>

            <th style='width: 5%;'>ProjectId</th>
            <th style='width: 15%;'>Title</th>
            <th style='width: 40%;'>Abstract</th>
            <th style='width: 20%;'>Keywords</th>
            <th style='width: 10%;'>PaperName</th>
            <th style='width: 10%;'>PaperURL</th>
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model)
        {
            <tr id="@item.ID">
                <td>@item.ProjectId</td>
                <td>@item.Title</td>
                <td>@item.Abstract</td>
                <td>@item.Keywords</td>
                <td>@item.PaperName</td>
                <td>@item.PaperURL</td>
            </tr>
        }
    </tbody>

What worked for me was to first add my SSH key of the new computer, I followed these instructions from GitLab - add SSH key. Note that since I'm on Win10, I had to do all these commands in Git Bash on Windows (it didn't work in regular DOS cmd Shell).

Then again in Git Bash, I had to do a git clone of the repo that I had problems with, and in my case I had to clone it to a different name since I already had it locally and didn't want to lose my commits. For example

git clone ssh://git@gitServerUrl/myRepo.git myRepo2

Then I got the prompt to add it to known hosts list, the question might be this one:

Are you sure you want to continue connecting (yes/no)?

I typed "yes" and it finally worked, you should typically get a message similar to this:

Warning: Permanently added '[your repo link]' (ECDSA) to the list of known hosts.

Note: if you are on Windows, make sure that you use Git Bash for all the commands, this did not work in regular cmd shell or powershell, I really had to do this in Git Bash.

Lastly I deleted the second clone repo (myRepo2 in the example) and went back to my first repo and I could finally do all the Git stuff like normal in my favorite editor VSCode.

You can also set

Listen All to NO

in the protocol dialog then in the IP address IP1 (say)

set enabled to Yes,

define yr IP address,

set TCP Dynamic to Blank and

TCP port to 1433 (or whatever)

In your case, hit Ctrl + Shift + P and type fold all.

I did change OS on my server quite a few times trying to get the most comfortable system.

It used to work very well most of the time but lastly I got this 502 Gateway error.

I use a php fpm socket for each account instead of keeping the same one for all. So if one crashes, at least the other applications keep running.

I used to have user and group www-data. But this changed on my Debian 8 with latest Nginx 1.8 and php5-fpm.

The default user is nginx and so is the group. To be sure of this, the best way is to check the /etc/group and /etc/passwd files. These can't lie.

It is there I found that now I have nginx in both and no longer www-data.

Maybe this can help some people still trying to find out why the error message keeps coming up.

It worked for me.

the simplest way:

sudo docker cp path/on/your/machine adam_ubuntu:/root/path_in_container

Note putting into the root path if you are copying something that needs to be picked up by the root using ~.

put this in your "head" of your index.html

 <style>
  html body{
    left: 0;
    right: 0;
    bottom: 0;
    top: 0;
    margin: 0;
  }
  </style>

Just another, more mathematical, way of doing the same thing but shorter:

arr.sort(function(a, b){
    var diff = new Date(a.updated_at) - new Date(b.updated_at);
    return diff/(Math.abs(diff)||1);
});

or in the slick lambda arrow style:

arr.sort((a, b) => {
    var diff = new Date(a.updated_at) - new Date(b.updated_at);
    return diff/(Math.abs(diff)||1);
});

This method can be done with any numeric input

In order to work with newer versions of Windows' policy of only allowing read access by default to the Program Files folder (unless you prompt for elevation with UAC, but that's another topic...), your application will have a settings folder under %userprofile%\appdata\local or %userprofile%\Local Settings\Application Data depending on which version of Windows you're running, for settings that are user specific. If you store settings for all users, then they'll be in the corresponding folder under C:\users or C:\Documents and Settings for all user profiles (ex: C:\users\public\appdata\local).

I had exact same error message with IIS10 and Windows 10. I tried everything listed here (and other internet pages as well) but it did not fixed it. What solved the issue was to install .NET Core Hosting a second time (I choose "Repair" button).

I'm 100% confident this is what fixed it because I had to deploy the same website to other laptops as well (different brands but all Windows 10). The same error message (500.19) occurred and reinstalling bundle fixed it again.

Unicode is a standard and about UTF-x you can think as a technical implementation for some practical purposes:

• UTF-8 - "size optimized": best suited for Latin character based data (or ASCII), it takes only 1 byte per character but the size grows accordingly symbol variety (and in worst case could grow up to 6 bytes per character)
• UTF-16 - "balance": it takes minimum 2 bytes per character which is enough for existing set of the mainstream languages with having fixed size on it to ease character handling (but size is still variable and can grow up to 4 bytes per character)
• UTF-32 - "performance": allows using of simple algorithms as result of fixed size characters (4 bytes) but with memory disadvantage

Google wrote some code to assist with this. Here are some examples: Example using InfoBubble, Styled markers and Info Window Custom (using OverlayView).

The code in the links above take different routes to achieve similar results. The gist of it is that it is not easy to style InfoWindows directly, and it might be easier to use the additional InfoBubble class instead of InfoWindow, or to override GOverlay. Another option would be to modify the elements of the InfoWindow using javascript (or jQuery), like later ATOzTOA suggested.

Possibly the simplest of these examples is using InfoBubble instead of InfoWindow. InfoBubble is available by importing this file (which you should host yourself): http://google-maps-utility-library-v3.googlecode.com/svn/trunk/infobubble/src/infobubble.js

InfoBubble's Github project page.

InfoBubble is very stylable, compared to InfoWindow:

 infoBubble = new InfoBubble({
      map: map,
      content: '<div class="mylabel">The label</div>',
      position: new google.maps.LatLng(-32.0, 149.0),
      shadowStyle: 1,
      padding: 0,
      backgroundColor: 'rgb(57,57,57)',
      borderRadius: 5,
      arrowSize: 10,
      borderWidth: 1,
      borderColor: '#2c2c2c',
      disableAutoPan: true,
      hideCloseButton: true,
      arrowPosition: 30,
      backgroundClassName: 'transparent',
      arrowStyle: 2
});

infoBubble.open();

You can also call it with a given map and marker to open on:

infoBubble.open(map, marker);

As another example, the Info Window Custom example extends the GOverlay class from the Google Maps API and uses this as a base for creating a more flexible info window. It first creates the class:

/* An InfoBox is like an info window, but it displays
 * under the marker, opens quicker, and has flexible styling.
 * @param {GLatLng} latlng Point to place bar at
 * @param {Map} map The map on which to display this InfoBox.
 * @param {Object} opts Passes configuration options - content,
 *   offsetVertical, offsetHorizontal, className, height, width
 */
function InfoBox(opts) {
  google.maps.OverlayView.call(this);
  this.latlng_ = opts.latlng;
  this.map_ = opts.map;
  this.offsetVertical_ = -195;
  this.offsetHorizontal_ = 0;
  this.height_ = 165;
  this.width_ = 266;

  var me = this;
  this.boundsChangedListener_ =
    google.maps.event.addListener(this.map_, "bounds_changed", function() {
      return me.panMap.apply(me);
    });

  // Once the properties of this OverlayView are initialized, set its map so
  // that we can display it.  This will trigger calls to panes_changed and
  // draw.
  this.setMap(this.map_);
}

after which it proceeds to override GOverlay:

InfoBox.prototype = new google.maps.OverlayView();

You should then override the methods you need: createElement, draw, remove and panMap. It gets rather involved, but in theory you are just drawing a div on the map yourself now, instead of using a normal Info Window.

First check to see if the string's length needs to be shortened, then add spaces until it is as long as the field length.

fieldLength = 15
string1 = string1[0:15] # If it needs to be shortened, shorten it
while len(string1) < fieldLength:
    rand += " "

$('#myTable tr').click(function(){
    $(this).remove();
    return false;
});

Even a better one

$("#MyTable").on("click", "#DeleteButton", function() {
   $(this).closest("tr").remove();
});

This is a very good and reliable solution: http://vinsol.com/blog/2014/10/01/handling-back-button-press-inside-fragments/

The guy has made an abstract fragment that handles the backPress behaviour and is switching between the active fragments using the strategy pattern.

For some of you there maybe a little drawback in the abstract class...

Shortly, the solution from the link goes like this:

// Abstract Fragment handling the back presses

public abstract class BackHandledFragment extends Fragment {
    protected BackHandlerInterface backHandlerInterface;
    public abstract String getTagText();
    public abstract boolean onBackPressed();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        if(!(getActivity()  instanceof BackHandlerInterface)) {
            throw new ClassCastException("Hosting activity must implement BackHandlerInterface");
        } else {
            backHandlerInterface = (BackHandlerInterface) getActivity();
        }
    }

    @Override
    public void onStart() {
        super.onStart();

        // Mark this fragment as the selected Fragment.
        backHandlerInterface.setSelectedFragment(this);
    }

    public interface BackHandlerInterface {
        public void setSelectedFragment(BackHandledFragment backHandledFragment);
    }
}   

And usage in the activity:

// BASIC ACTIVITY CODE THAT LETS ITS FRAGMENT UTILIZE onBackPress EVENTS 
// IN AN ADAPTIVE AND ORGANIZED PATTERN USING BackHandledFragment

public class TheActivity extends FragmentActivity implements BackHandlerInterface {
    private BackHandledFragment selectedFragment;

    @Override
    public void onBackPressed() {
        if(selectedFragment == null || !selectedFragment.onBackPressed()) {
            // Selected fragment did not consume the back press event.
            super.onBackPressed();
        }
    }

    @Override
    public void setSelectedFragment(BackHandledFragment selectedFragment) {
        this.selectedFragment = selectedFragment;
    }
}

just posting in case anyone else has the same error...

I was using 'await' outside of an 'async' function and for whatever reason that results in a 'missing ) after argument list' error.

The solution was to make the function asynchronous

function functionName(args) {}

becomes

async function functionName(args) {}

rm -rf /var/log/jenkins too big the log

A variation of the expression by @Gumbo that makes use of \K for resetting match positions to prevent the inclusion of number blocks in the match. Usable in PCRE regex flavours.

123-\K(?:(?:apple|banana)(?=-456)|456\K)

Matches:

Match 1  apple
Match 2  banana
Match 3

Based on the @AndrewCox 's answer with some minor improvements:

from http.client import HTTPSConnection
from base64 import b64encode


client = HTTPSConnection("www.google.com")
user = "user_name"
password = "password"
headers = {
    "Authorization": "Basic {}".format(
        b64encode(bytes(f"{user}:{password}", "utf-8")).decode("ascii")
    )
}
client.request('GET', '/', headers=headers)
res = client.getresponse()
data = res.read()

Note, you should set encoding if you use bytes function instead of b"".

One more important thing to note!!! In example above it's described how to use

$.ajax({
    type     : 'POST',
    dataType : 'json', 
    url      : 'another-remote-server',
    ...
});

JQuery 1.6 and lower has a bug with cross-domain XHR. According to Firebug no requests except OPTIONS were sent. No POST. At all.

Spent 5 hours testing/tuning my code. Adding a lot of headers on the remote server (script). Without any effect. But later, I've updated JQuery lib to 1.6.4, and everything works like a charm.

The ternary operator can only be the right side of an assignment and not a statement of its own.

Write it like this:

string[] files = Directory.GetFiles(@".\Archive", "*.zip");

. is for relative to the folder where you started your exe, and @ to allow \ in the name.

When using filters, you pass it as a second parameter. You can also add a third parameter to specify if you want to search recursively for the pattern.

In order to get the folder where your .exe actually resides, use:

var executingPath = Path.GetDirectoryName(Assembly.GetEntryAssembly().Location);

In Bootstrap 3.3.x make sure you use the scrollspy JavaScript capability to track active elements. It's easy to include it in your HTML. Just do the following:

<body data-spy="scroll" data-target="Id or class of the element you want to track">

In most cases I usually track active elements on my navbar, so I do the following:

<body data-spy="scroll" data-target=".navbar-fixed-top" >

Now in your CSS you can target .navbar-fixed-top .active a:

.navbar-fixed-top .active a { 
    // Put in some styling 
}

This should work if you are tracking active li elements in your top fixed navigation bar.

Delete all spaces and line breaks between <textarea> opening and closing </textarea> tags.

<textarea placeholder="YOUR TEXT"></textarea>  ///Correct one

<textarea placeholder="YOUR TEXT"> </textarea>  ///Bad one It's treats as a value so browser won't display the Placeholder value

<textarea placeholder="YOUR TEXT"> 
</textarea>  ///Bad one 

This is an adapted version of the answer given by Vivien Barousse with the update from Vulcan applied. In this example I use sliders to dynamically retreive the RGB values from three sliders and display that color in a rectangle. Then in method toHex() I use the values to create a color and display the respective Hex color code.

This example does not include the proper constraints for the GridBagLayout. Though the code will work, the display will look strange.

public class HexColor
{

  public static void main (String[] args)
  {
   JSlider sRed = new JSlider(0,255,1);
   JSlider sGreen = new JSlider(0,255,1);
   JSlider sBlue = new JSlider(0,255,1);
   JLabel hexCode = new JLabel();
   JPanel myPanel = new JPanel();
   GridBagLayout layout = new GridBagLayout();
   JFrame frame = new JFrame();

   //set frame to organize components using GridBagLayout 
   frame.setLayout(layout);

   //create gray filled rectangle 
   myPanel.paintComponent();
   myPanel.setBackground(Color.GRAY);

   //In practice this code is replicated and applied to sGreen and sBlue. 
   //For the sake of brevity I only show sRed in this post.
   sRed.addChangeListener(
         new ChangeListener()
         {
             @Override
             public void stateChanged(ChangeEvent e){
                 myPanel.setBackground(changeColor());
                 myPanel.repaint();
                 hexCode.setText(toHex());
         }
         }
     );
   //add each component to JFrame
   frame.add(myPanel);
   frame.add(sRed);
   frame.add(sGreen);
   frame.add(sBlue);
   frame.add(hexCode);
} //end of main

  //creates JPanel filled rectangle
  protected void paintComponent(Graphics g)
  {
      super.paintComponent(g);
      g.drawRect(360, 300, 10, 10);
      g.fillRect(360, 300, 10, 10);
  }

  //changes the display color in JPanel
  private Color changeColor()
  {
    int r = sRed.getValue();
    int b = sBlue.getValue();
    int g = sGreen.getValue();
    Color c;
    return  c = new Color(r,g,b);
  }

  //Displays hex representation of displayed color
  private String toHex()
  {
      Integer r = sRed.getValue();
      Integer g = sGreen.getValue();
      Integer b = sBlue.getValue();
      Color hC;
      hC = new Color(r,g,b);
      String hex = Integer.toHexString(hC.getRGB() & 0xffffff);
      while(hex.length() < 6){
          hex = "0" + hex;
      }
      hex = "Hex Code: #" + hex;
      return hex;
  }
}

A huge thank you to both Vivien and Vulcan. This solution works perfectly and was super simple to implement.

Put your image in a container div then use the following CSS (changing the dimensions to suit your image.

.imageContainer{
        position: absolute;
        width: 100px; /*the image width*/
        height: 100px; /*the image height*/
        left: 50%;
        top: 50%;
        margin-left: -50px; /*half the image width*/
        margin-top: -50px; /*half the image height*/
    }

Using pure java-script, here is a working code example

<input type="checkbox" name="fruit1" checked/>
<input type="checkbox" name="fruit2" checked />
<input type="checkbox" name="fruit3" checked />
<input type="checkbox" name="other1" checked />
<input type="checkbox" name="other2" checked />
<br>
<input type="button" name="check" value="count checked checkboxes name starts with fruit*" onClick="checkboxes();" />


<script>
function checkboxes()
{
var inputElems = document.getElementsByTagName("input"),
count = 0;
for (var i=0; i<inputElems.length; i++) {       
if (inputElems[i].type == "checkbox" && inputElems[i].checked == true && 
inputElems[i].name.indexOf('fruit') == 0) 
{
count++;

}

}
alert(count);
}
</script>
