Try this...

$('p').append('<span id="add_here">new-dynamic-text</span>');

OR if there is an existing span, do this.

$('p').children('span').text('new-dynamic-text');

After searching different websites looking for a solution as to how to separate the full path from the file name once the full one-piece information has been obtained from the Open File Dialog, and seeing how "complex" the solutions given were for an Excel newcomer like me, I wondered if there could be a simpler solution. So I started to work on it on my own and I came to this possibility. (I have no idea if somebody got the same idea before. Being so simple, if somebody has, I excuse myself.)

Dim fPath As String
Dim fName As String
Dim fdString As String

fdString = (the OpenFileDialog.FileName)

'Get just the path by finding the last "\" in the string from the end of it
 fPath = Left(fdString, InStrRev(fdString, "\"))

'Get just the file name by finding the last "\" in the string from the end of it
 fName = Mid(fdString, InStrRev(fdString, "\") + 1)

'Just to check the result
 Msgbox "File path: " & vbLF & fPath & vbLF & vblF & "File name: " & vbLF & fName

AND THAT'S IT!!! Just give it a try, and let me know how it goes...

Thought I'd add my own example that helped me see the difference using the value 1.3 when adding or multiplying with another float, decimal, and double .

1.3 float ADDED to 1.3 of different types:

|float              | double | decimal |
+-------------------+------------+-----+
|2.5999999046325684 | 2.6    | 2.60000 |

1.3 float MULTIPLIED by 1.3 of different types:

| float              | double             | decimal      |
+--------------------+--------------------+--------------+
| 1.6899998760223411 | 1.6900000000000002 | 1.6900000000 |

This is using MySQL 6.7

The compiler cannot guess what should be passed for the base constructor argument. You have to do it explicitly:

public class child : parent {
    public child(int i) : base(i) {
        Console.WriteLine("child");
    }
}

How to use

Create a new TimeSpan object

    const ts = TimeSpan.zero;

    const milliseconds = 10000; // 1 second

    // by using the constructor
    const ts1 = new TimeSpan(milliseconds);

    // or as an alternative you can use the static factory method
    const ts2 = TimeSpan.fromMilliseconds(milliseconds);

    const seconds = 86400; // 1 day
    const ts = TimeSpan.fromSeconds(seconds);

    const minutes = 1440; // 1 day
    const ts = TimeSpan.fromMinutes(minutes);

    const hours = 24; // 1 day
    const ts = TimeSpan.fromHours(hours);

    const days = 1; // 1 day
    const ts = TimeSpan.fromDays(days);

    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const ts = TimeSpan.fromTime(hours, minutes, seconds);

    const days = 1;
    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const milliseconds = 1;
    const ts = TimeSpan.fromTime(days, hours, minutes, seconds, milliseconds);

    const ts = TimeSpan.maxValue;

    const ts = TimeSpan.minValue;

    const ts = TimeSpan.minValue;

    const ts1 = TimeSpan.fromDays(1);
    const ts2 = TimeSpan.fromHours(1);
    const ts = ts1.add(ts2);

    console.log(ts.days);               // 1
    console.log(ts.hours);              // 1
    console.log(ts.minutes);            // 0
    console.log(ts.seconds);            // 0
    console.log(ts.milliseconds);           // 0

    const ts1 = TimeSpan.fromDays(1);
    const ts2 = TimeSpan.fromHours(1);
    const ts = ts1.subtract(ts2);

    console.log(ts.days);               // 0
    console.log(ts.hours);              // 23
    console.log(ts.minutes);            // 0
    console.log(ts.seconds);            // 0
    console.log(ts.milliseconds);           // 0

    const days = 1;
    const hours = 1;
    const minutes = 1;
    const seconds = 1;
    const milliseconds = 1;
    const ts = TimeSpan.fromTime2(days, hours, minutes, seconds, milliseconds);

    console.log(ts.days);               // 1
    console.log(ts.hours);              // 1
    console.log(ts.minutes);            // 1
    console.log(ts.seconds);            // 1
    console.log(ts.milliseconds);           // 1

    console.log(ts.totalDays)           // 1.0423726967592593;
    console.log(ts.totalHours)          // 25.016944722222224;
    console.log(ts.totalMinutes)            // 1501.0166833333333;
    console.log(ts.totalSeconds)            // 90061.001;
    console.log(ts.totalMilliseconds);      // 90061001;

First of adding the background colour that you want as the colour of your border, then

change the cropToPadding to true and after that add padding.

Then you will have your border for your imageView.

5 step to do what you want if you made the pull request from a forked repository:

1. reopen the pull request
2. checkout to the branch which you made the pull request
3. reset commit to the last master commit(that means remove all you new code)
4. git push --force
5. delete your forked repository which made the pull request

And everything is done, good luck!

You can achieve this by using simply as a returns set of records using return query.

CREATE OR REPLACE FUNCTION schemaName.get_two_users_from_school(schoolid bigint)
 RETURNS SETOF record
 LANGUAGE plpgsql
AS $function$
begin

 return query
  SELECT id, name FROM schemaName.user where school_id = schoolid;

end;
$function$

And call this function as : select * from schemaName.get_two_users_from_school(schoolid) as x(a bigint, b varchar);

DECLARE @Daysforward int
SELECT @Daysforward = 25 (no of days required)
Select * from table name

where CAST( columnDate AS date) < DATEADD(day,1+@Daysforward,CAST(GETDATE() AS date))

The "Issue 2" answer given by @Sagar works for the majority of git servers such as gitorious.

However, there will be a name clash in a system like gitolite where the public ssh keys are checked in as files named with the username, ie keydir/jenkins.pub. What if there are multiple jenkins servers that need to access the same gitolite server?

(Note: this is about running the Jenkins daemon not running a build job as a user (addressed by @Sagar's "Issue 1").)

So in this case you do need to run the Jenkins daemon as a different user.

There are two steps:

Step 1

The main thing is to update the JENKINS_USER environment variable. Here's a patch showing how to change the user to ptran.

Step 3

Restart jenkins

$order = new WC_Order( $post_id ); 

If you

echo $order->id;

then you'll be returned the id of the post from which the order is made. As you've already got that, it's probably not what you want.

echo $order->get_order_number();

will return the id of the order (with a # in front of it). To get rid of the #,

echo trim( str_replace( '#', '', $order->get_order_number() ) );

as per the accepted answer.

This is the initial database of the data source when you connect.

Edited for clarity:

If you have multiple databases in your SQL Server instance and you don't want to use the default database, you need some way to specify which one you are going to use.

It is defenetly not a appropriate answer, but it is a small hint.

If you want to make use of static files in your App. You should put them as resources or as assets. But, if U have memory concerns like to keep your APK small, then you need to change your App design in such a way that,

instead of putting them as resources, while running your App(after installation) you can take the files(defenately different files as user may not keep files what you need) from SD Card. For this U can use ContentResolver to take audio, Image files on user selection.

With this you can give the user another feature like he can load audio/image files to the app on his own choice.

Instead of using http GET, use http POST. And JSON. Or XML

This is how your request stream to the server would look like.

POST /appointments HTTP/1.0
Content-Type: application/json
Content-Length: (calculated by your utility)

{users: [user:{id:id1}, user:{id:id2}]}

Or in XML,

POST /appointments HTTP/1.0
Content-Type: application/json
Content-Length: (calculated by your utility)

<users><user id='id1'/><user id='id2'/></users>

You could certainly continue using GET as you have proposed, as it is certainly simpler.

/appointments?users=1d1,1d2

Which means you would have to keep your data structures very simple.

However, if/when your data structure gets more complex, http GET and without JSON, your programming and ability to recognise the data gets very difficult.

Therefore,unless you could keep your data structure simple, I urge you adopt a data transfer framework. If your requests are browser based, the industry usual practice is JSON. If your requests are server-server, than XML is the most convenient framework.

JQuery

If your client is a browser and you are not using GWT, you should consider using jquery REST. Google on RESTful services with jQuery.

Here's an interesting benchmark http://zi.fi/shootout/

Just like Perl,

loop1:
    for (var i in set1) {
loop2:
        for (var j in set2) {
loop3:
            for (var k in set3) {
                break loop2;  // breaks out of loop3 and loop2
            }
        }
    }

as defined in EMCA-262 section 12.12. [MDN Docs]

Unlike C, these labels can only be used for continue and break, as Javascript does not have goto.

for removing the disabled properties

 $('#inputDisabled').removeAttr('Disabled');

for adding the disabled properties

 $('#inputDisabled').attr('disabled', 'disabled' );

You can also rebuild your string character by character, excluding the characters that you want to get rid of.

Here's an extension method to do this:

    static public string RemoveAny(this string s, string charsToRemove)
    {
        var result = "";
        foreach (var c in s)
            if (charsToRemove.Contains(c))
                continue;
            else
                result += c;

        return result;
    }

It's not slick or fancy, but it works well.

Use like this:

string newString = "My_String".RemoveAny("_"); //yields "MyString"

The solution that work for me is the following

app.directive('onFinishRender', ['$timeout', '$parse', function ($timeout, $parse) {
    return {
        restrict: 'A',
        link: function (scope, element, attr) {
            if (scope.$last === true) {
                $timeout(function () {
                    scope.$emit('ngRepeatFinished');
                    if (!!attr.onFinishRender) {
                        $parse(attr.onFinishRender)(scope);
                    }
                });
            }

            if (!!attr.onStartRender) {
                if (scope.$first === true) {
                    $timeout(function () {
                        scope.$emit('ngRepeatStarted');
                        if (!!attr.onStartRender) {
                            $parse(attr.onStartRender)(scope);
                        }
                    });
                }
            }
        }
    }
}]);

Controller code is the following

$scope.crearTooltip = function () {
     $('[data-toggle="popover"]').popover();
}

Html code is the following

<tr ng-repeat="item in $data" on-finish-render="crearTooltip()">

Use chrome.tabs.query() like this:

chrome.tabs.query({active: true, lastFocusedWindow: true}, tabs => {
    let url = tabs[0].url;
    // use `url` here inside the callback because it's asynchronous!
});

This requires that you request access to the chrome.tabs API in your extension manifest:

"permissions": [ ...
   "tabs"
]

It's important to note that the definition of your "current tab" may differ depending on your extension's needs.

Setting lastFocusedWindow: true in the query is appropriate when you want to access the current tab in the user's focused window (typically the topmost window).

Setting currentWindow: true allows you to get the current tab in the window where your extension's code is currently executing. For example, this might be useful if your extension creates a new window / popup (changing focus), but still wants to access tab information from the window where the extension was run.

I chose to use lastFocusedWindow: true in this example, because Google calls out cases in which currentWindow may not always be present.

You are free to further refine your tab query using any of the properties defined here: chrome.tabs.query

If you have a cancel button on your form, you can set the Form.CancelButton property to that button and then pressing escape will effectively 'click the button'.

If you don't have such a button, check out the Form.KeyPreview property.

The solution you are looking for is in Angular's official tutorial. In this tutorial Phones are loaded from a JSON file using Angulars $http service . In the code below we use $http.get to load a phones.json file saved in the phones directory:

var phonecatApp = angular.module('phonecatApp', []);   
phonecatApp.controller('PhoneListCtrl', function ($scope, $http) {
 $http.get('phones/phones.json').success(function(data) {
$scope.phones = data;
}); 
$scope.orderProp = 'age';
});

We then iterate over the phones:

<table>
  <tbody ng-repeat="i in phones">
    <tr><td>{{i.name}}</td><td>{{$index}}</td></tr>
    <tr ng-repeat="e in i.details">
       <td>{{$index}}</td>
       <td>{{e.foo}}</td>
       <td>{{e.bar}}</td></tr>
  </tbody>
</table>

while spring.jpa.open-in-view was true, I didn't have any problem with getOne but after setting it to false , i got LazyInitializationException. Then problem was solved by replacing with findById.
Although there is another solution without replacing the getOne method, and that is put @Transactional at method which is calling repository.getOne(id). In this way transaction will exists and session will not be closed in your method and while using entity there would not be any LazyInitializationException.

My solution is:

• In main activity:

  char separator =DecimalFormatSymbols.getInstance().getDecimalSeparator(); textViewPitchDeadZone.setKeyListener(DigitsKeyListener.getInstance("0123456789" + separator));

• In xml file: android:imeOptions="flagNoFullscreen" android:inputType="numberDecimal"

and I took the double in the editText as a String.

They Say Use NSUserDefaults

When I was implementing long term (after app close) data storage for the first time, everything I read online pointed me towards NSUserDefaults. However, I wanted to store a dictionary and, although possible, it was proving to be a pain. I spent hours trying to get type-errors to go away.

NSUserDefaults is Also Limited in Function

Further reading revealed how the read/write of NSUserDefaults really forces the app to read/write everything or nothing, all at once, so it isn't efficient. Then I learned that retrieving an array isn't straight forward. I realized that if you're storing more than a few strings or booleans, NSUserDefaults really isn't ideal.

It's also not scalable. If you're learning how to code, learn the scalable way. Only use NSUserDefaults for storing simple strings or booleans related to preferences. Store arrays and other data using Core Data, it's not as hard as they say. Just start small.

Update: Also, if you add Apple Watch support, there's another potential consideration. Your app's NSUserDefaults is now automatically sent to the Watch Extension.

Using Core Data

So I ignored the warnings about Core Data being a more difficult solution and started reading. Within three hours I had it working. I had my table array being saved in Core Data and reloading the data upon opening the app back up! The tutorial code was easy enough to adapt and I was able to have it store both title and detail arrays with only a little extra experimenting.

So for anyone reading this post who's struggling with NSUserDefault type issues or whose need is more than storing strings, consider spending an hour or two playing with core data.

Here's the tutorial I read:

http://www.raywenderlich.com/85578/first-core-data-app-using-swift

If you didn't check "Core Data"

If you didn't check "Core Data"when you created your app, you can add it after and it only takes five minutes:

How to Delete from Core Data Lists

Delete Data from Coredata Swift

I know its a little bit late but someone may find this useful in future.

STEP 1:

Login to facebook Developer -> Your App

In Settings -> Basic -> Contact Email. (Give any email)

STEP 2:

And in 'App Review' Tab : change

Do you want to make this app and all its live features available to the general public? Yes

And you app will be live now ..

Also worth noting window.scrollBy(dx,dy) (ref)

I can relate to the problem, there should be a shorthand like...

border: 1px solid red top bottom left;

Of course that doesn't work! Kobi's answer gave me an idea. Let's say you want to do top, bottom and left, but not right. Instead of doing border-top: border-left: border-bottom: (three statements) you could do two like this, the zero cancels out the right side.

border: 1px dashed yellow;
border-width:1px 0 1px 1px;

Two statements instead of three, small improvement :-D

There's also byte_lite, compatible with C++98, C++11 and later.

The font may exist with different names, and not at all on some systems, so you need to use different variations and fallback to get the closest possible look on all systems:

font-family: "Comic Sans MS", "Comic Sans", cursive;

Be careful what you use this font for, though. Many consider it as ugly and overused, so it should not be use for something that should look professional.

you try the code which gives JSON without rowdatapacket:

var ret = [];
conn.query(SQLquery, function(err, rows, fields) {
    if (err)
        alert("...");
    else {
        ret = JSON.stringify(rows);
    }
    doStuffwithTheResult(ret);
}

I liked Marc's answer, but needed the Contains matching to be CaSe InSenSiTiVe.

This was the solution:

bool b = listOfStrings.Any(s => myString.IndexOf(s, StringComparison.OrdinalIgnoreCase) >= 0))

elaborating @john-mee 's answer, if you have arbitrarily long data but don't need strictly unique colors:

for python 2:

from itertools import cycle
cycol = cycle('bgrcmk')

for X,Y in data:
    scatter(X, Y, c=cycol.next())

for python 3:

from itertools import cycle
cycol = cycle('bgrcmk')

for X,Y in data:
    scatter(X, Y, c=next(cycol))

this has the advantage that the colors are easy to control and that it's short.

You could try :

• run the emulator from the console manually and see whether adb can connect("see") it from android studio. Does it run at all?
• delete avd , recreate a new one for testing, always a good idea in 2.0. lot's of stuff is changing ( instant run etc.)
• what does adb say from console ? adb kill-server , adb start-server, start an emulator, then adb devices does it list your emulator ?

Best to use ResultSet.next() along with the do {...} while() syntax for this.

The "check for any results" call ResultSet.next() moves the cursor to the first row, so use the do {...} while() syntax to process that row while continuing to process remaining rows returned by the loop.

This way you get to check for any results, while at the same time also processing any results returned.

if(resultSet.next()) { // Checks for any results and moves cursor to first row,
    do { // Use 'do...while' to process the first row, while continuing to process remaining rows

    } while (resultSet.next());
}

HTML5's formaction does not work on old IE browsers. An easy fix, based on some of the responses above, is:

Step by step. .padEnd - Guarentees the length of the string

"The padEnd() method pads the current string with a given string (repeated, if needed) so that the resulting string reaches a given length. The padding is applied from the end (right) of the current string. The source for this interactive example is stored in a GitHub repository." source: developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/…

.substring - limits to the length you need

If you choose to add ellipses, append them to the output.

I gave 4 examples of common JavaScript usages. I highly recommend using the String prototype with Overloading for legacy support. It makes it much easier to implement and change later.

Because you might be using jdk1.5+ and there it is auto converting to int. So in your code its first returning Integer and then auto converted to int.

your code is same as

int abc = new Integer(123);

Another way of showing the number of rows and space occupied and ordering by it.

SELECT
     table_schema as `Database`,
     table_name AS `Table`,
     table_rows AS "Quant of Rows",
     round(((data_length + index_length) / 1024 / 1024/ 1024), 2) `Size in GB`
FROM information_schema.TABLES
WHERE table_schema = 'yourDatabaseName'
ORDER BY (data_length + index_length) DESC;  

The only string you have to substitute in this query is "yourDatabaseName".

You can use float on that particular div, e.g.

<div style="float:right;">

Float the div you want more space to have to the left as well:

<div style="float:left;">

If all else fails give the div on the right position:absolute and then move it as right as you want it to be.

<div style="position:absolute; left:-500px; top:30px;"> 

etc. Obviously put the style in a seperate stylesheet but this is just a quicker example.

Solution 1

If we consider a JavaScript integer to be a value of maximum 4294967295 (i.e. Math.pow(2,32)-1), then the following short solution will perfectly work:

function isPositiveInteger(n) {
    return n >>> 0 === parseFloat(n);
}

DESCRIPTION:

1. Zero-fill right shift operator does three important things:
   • truncates decimal part
     • 123.45 >>> 0 === 123
   • does the shift for negative numbers
     • -1 >>> 0 === 4294967295
   • "works" in range of MAX_INT
     • 1e10 >>> 0 === 1410065408
     • 1e7 >>> 0 === 10000000
2. parseFloat does correct parsing of string numbers (setting NaN for non numeric strings)

TESTS:

"0"                     : true
"23"                    : true
"-10"                   : false
"10.30"                 : false
"-40.1"                 : false
"string"                : false
"1234567890"            : true
"129000098131766699.1"  : false
"-1e7"                  : false
"1e7"                   : true
"1e10"                  : false
"1edf"                  : false
" "                     : false
""                      : false

Solution 2

Another way is good for all numeric values which are valid up to Number.MAX_VALUE, i.e. to about 1.7976931348623157e+308:

function isPositiveInteger(n) {
    return 0 === n % (!isNaN(parseFloat(n)) && 0 <= ~~n);
}

DESCRIPTION:

1. !isNaN(parseFloat(n)) is used to filter pure string values, e.g. "", " ", "string";
2. 0 <= ~~n filters negative and large non-integer values, e.g. "-40.1", "129000098131766699";
3. (!isNaN(parseFloat(n)) && 0 <= ~~n) returns true if value is both numeric and positive;
4. 0 === n % (...) checks if value is non-float -- here (...) (see 3) is evaluated as 0 in case of false, and as 1 in case of true.

TESTS:

"0"                     : true
"23"                    : true
"-10"                   : false
"10.30"                 : false
"-40.1"                 : false
"string"                : false
"1234567890"            : true
"129000098131766699.1"  : false
"-1e10"                 : false
"1e10"                  : true
"1edf"                  : false
" "                     : false
""                      : false

DEMO: http://jsfiddle.net/5UCy4/14/

The previous version:

function isPositiveInteger(n) {
    return n == "0" || ((n | 0) > 0 && n % 1 == 0);
}

Normally you can set up a git repo by just using the init command

git init

In your case, there is already a repo on a remote available. Dependent on how you access your remote repo ( with username inside the url or a ssh key which handles verification ) use just the clone command:

git clone git@[my.url.com]:[git-repo-name].git

There are also other ways to clone the repo. This way you call it if you have a ssh key setup on your machine which verifies on pulling your repository. There are other combinations of the url if you want to include your password and username inside to login into your remote repository.

Only this worked for me (AndroidX support library):

 <com.google.android.material.appbar.AppBarLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@null"
            android:theme="@style/AppTheme.AppBarOverlay"
            android:translationZ="0.1dp"
            app:elevation="0dp">

            <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="@null"
                app:popupTheme="@style/AppTheme.PopupOverlay" />

        </com.google.android.material.appbar.AppBarLayout>

This code removes background in all necessary views and also removes shadow from AppBarLayout (which was a problem)

Answer was found here: remove shadow below AppBarLayout widget android

Within Crystal, you can do it by creating a formula that uses the ToNumber function. It might be a good idea to code for the possibility that the field might include non-numeric data - like so:

If NumericText ({field}) then ToNumber ({field}) else 0

Alternatively, you might find it easier to convert the field's datatype within the query used in the report.

Appending to and copying slices

The variadic function append appends zero or more values x to s of type S, which must be a slice type, and returns the resulting slice, also of type S. The values x are passed to a parameter of type ...T where T is the element type of S and the respective parameter passing rules apply. As a special case, append also accepts a first argument assignable to type []byte with a second argument of string type followed by .... This form appends the bytes of the string.

append(s S, x ...T) S  // T is the element type of S

s0 := []int{0, 0}
s1 := append(s0, 2)        // append a single element     s1 == []int{0, 0, 2}
s2 := append(s1, 3, 5, 7)  // append multiple elements    s2 == []int{0, 0, 2, 3, 5, 7}
s3 := append(s2, s0...)    // append a slice              s3 == []int{0, 0, 2, 3, 5, 7, 0, 0}

Passing arguments to ... parameters

If f is variadic with final parameter type ...T, then within the function the argument is equivalent to a parameter of type []T. At each call of f, the argument passed to the final parameter is a new slice of type []T whose successive elements are the actual arguments, which all must be assignable to the type T. The length of the slice is therefore the number of arguments bound to the final parameter and may differ for each call site.

The answer to your question is example s3 := append(s2, s0...) in the Go Programming Language Specification. For example,

s := append([]int{1, 2}, []int{3, 4}...)

You are experiencing this issue for two reasons.

• The JPQL Query is not valid.
• You have not created an association between your entities that the underlying JPQL query can utilize.

When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)

User.java

@Entity
@Table(name="user")
public class User {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="iduser")
    private Long idUser;

    @Column(name="user_name")
    private String userName;

    @OneToOne()
    @JoinColumn(name="idarea")
    private Area area;

    public Long getIdUser() {
        return idUser;
    }

    public void setIdUser(Long idUser) {
        this.idUser = idUser;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public Area getArea() {
        return area;
    }

    public void setArea(Area area) {
        this.area = area;
    }
}

Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:

@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")

While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.

Area.java

@Entity
@Table(name = "area")
public class Area {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    @Column(name="idarea")
    private Long idArea;

    @Column(name="area_name")
    private String areaName;

    @OneToOne(fetch=FetchType.LAZY, mappedBy="area")
    private User user;

    public Long getIdArea() {
        return idArea;
    }

    public void setIdArea(Long idArea) {
        this.idArea = idArea;
    }

    public String getAreaName() {
        return areaName;
    }

    public void setAreaName(String areaName) {
        this.areaName = areaName;
    }

    public User getUser() {
        return user;
    }

    public void setUser(User user) {
        this.user = user;
    }
}

This is just an explanation not addressed in other answers

At least in recent versions of Mysql, your first query is not committed.

If you query it under the same session you will see the changes, but if you query it from a different session, the changes are not there, they are not committed.

What's going on?

When you open a transaction, and a query inside it fails, the transaction keeps open, it does not commit nor rollback the changes.

So BE CAREFUL, any table/row that was locked with a previous query likeSELECT ... FOR SHARE/UPDATE, UPDATE, INSERT or any other locking-query, keeps locked until that session is killed (and executes a rollback), or until a subsequent query commits it explicitly (COMMIT) or implicitly, thus making the partial changes permanent (which might happen hours later, while the transaction was in a waiting state).

That's why the solution involves declaring handlers to immediately ROLLBACK when an error happens.

Extra

Inside the handler you can also re-raise the error using RESIGNAL, otherwise the stored procedure executes "Successfully"

BEGIN
    DECLARE EXIT HANDLER FOR SQLEXCEPTION 
        BEGIN
            ROLLBACK;
            RESIGNAL;
        END;

    START TRANSACTION;
        #.. Query 1 ..
        #.. Query 2 ..
        #.. Query 3 ..
    COMMIT;
END

You can use .indexOf() and .substr() like this:

var val = $("input").val();
var myString = val.substr(val.indexOf("?") + 1)

You can test it out here. If you're sure of the format and there's only one question mark, you can just do this:

var myString = $("input").val().split("?").pop();

<%= link_to "http://www.facebook.com/sharer.php?u=" + article_url(article, :text => article.title), :class => "btn btn-primary" do %>   <i class="fa fa-facebook">     Facebook Share    </i> <%end%> 

I am assuming that current_article_url is http://0.0.0.0:4567/link_to_title

You can try this:

For Date:

$date = new DateTime($from_date);
$date = $date->format('d-m-Y');

For Time:

$time = new DateTime($from_date);
$time = $time->format('H:i:s');

It helps me:

sudo nano /etc/postgresql/9.x/main/pg_hba.conf

and change this line:

Database administrative login by Unix domain socket
local   all             postgres                                md5

to

Database administrative login by Unix domain socket
local   all             postgres                                trust

2. Restart the server

   sudo service postgresql restart

3. Login into psql and set password

   psql -U postgres

ALTER USER postgres with password 'new password';

4. Again open the file pg_hba.conf and change this line:

Database administrative login by Unix domain socket
    local   all             postgres                                trust

to

    Database administrative login by Unix domain socket
    local   all             postgres                                md5

5. Restart the server

   sudo service postgresql restart

First off, Xvfb doesn't read configuration from xorg.conf. Xvfb is a variant of the KDrive X servers and like all members of that family gets its configuration from the command line.

It is true that XRandR and Xinerama are mutually exclusive, but in the case of Xvfb there's no Xinerama in the first place. You can enable the XRandR extension by starting Xvfb using at least the following command line options

Xvfb +extension RANDR [further options]

Runtime is somewhat opposite to design-time and compile-time/link-time. Historically it comes from slow mainframe environment where machine-time was expensive.

you can use .is():

  $( "ul" ).click(function( event ) {
      var target = $( event.target );
      if ( target.is( "li" ) ) {
         target.css( "background-color", "red" );
      }
  });

NB. Constructor function names should start with a capital letter to distinguish them from ordinary functions, e.g. MyClass instead of myClass.

Either you can call init from your constructor function:

var myObj = new MyClass(2, true);

function MyClass(v1, v2) 
{
    // ...

    // pub methods
    this.init = function() {
        // do some stuff        
    };

    // ...

    this.init(); // <------------ added this
}

Or more simply you could just copy the body of the init function to the end of the constructor function. No need to actually have an init function at all if it's only called once.

Set positioning to absolute. That will solve the problem immediately, but might cause some problems in layout later. You can always figure out a way around them ;)

Example:

position:absolute;

Guys, I found that JQuery has only one effect: the page is reloaded when the back button is pressed. This has nothing to do with "ready".

How does this work? Well, JQuery adds an onunload event listener.

// http://code.jquery.com/jquery-latest.js
jQuery(window).bind("unload", function() { // ...

By default, it does nothing. But somehow this seems to trigger a reload in Safari, Opera and Mozilla -- no matter what the event handler contains.

[edit(Nickolay): here's why it works that way: webkit.org, developer.mozilla.org. Please read those articles (or my summary in a separate answer below) and consider whether you really need to do this and make your page load slower for your users.]

Can't believe it? Try this:

<body onunload=""><!-- This does the trick -->
<script type="text/javascript">
    alert('first load / reload');
    window.onload = function(){alert('onload')};
</script>
<a href="http://stackoverflow.com">click me, then press the back button</a>
</body>

You will see similar results when using JQuery.

You may want to compare to this one without onunload

<body><!-- Will not reload on back button -->
<script type="text/javascript">
    alert('first load / reload');
    window.onload = function(){alert('onload')};
</script>
<a href="http://stackoverflow.com">click me, then press the back button</a>
</body>

It's been many functions, macros and objects since I posted this question. The way I handled it, which is mentioned in one of the answers here, is by creating a string function that handles the errors that get generate by the vlookup function, and returns either nothing or the vlookup result if any.

Function fsVlookup(ByVal pSearch As Range, ByVal pMatrix As Range, ByVal pMatColNum As Integer) As String
    Dim s As String
    On Error Resume Next
    s = Application.WorksheetFunction.VLookup(pSearch, pMatrix, pMatColNum, False)
    If IsError(s) Then
        fsVlookup = ""
    Else
        fsVlookup = s
    End If
End Function

One could argue about the position of the error handling or by shortening this code, but it works in all cases for me, and as they say, "if it ain't broke, don't try and fix it".

You can access the MySQL command line with XAMPP for Windows

1. click XAMPP icon to launch its cPanel

2. click on Shell button

3. Type this mysql -h localhost -u root and click enter

You should see all the command lines and what they do

Setting environment for using XAMPP for Windows.

Usage: mysql [OPTIONS] [database]

Default options are read from the following files in the given order:
C:\WINDOWS\my.ini C:\WINDOWS\my.cnf C:\my.ini C:\my.cnf C:\xampp\mysql\my.ini C:\xampp\mysql\my.cnf C:\xampp\mysql\bin\my.ini C:\xampp\mysql\bin\my.cnf
The following groups are read: mysql client client-server client-mariadb
The following options may be given as the first argument:
--print-defaults        Print the program argument list and exit.
--no-defaults           Don't read default options from any option file.
--defaults-file=#       Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.

  -?, --help          Display this help and exit.
  -I, --help          Synonym for -?
  --abort-source-on-error
Abort 'source filename' operations in case of errors
  --auto-rehash       Enable automatic rehashing. One doesn't need to use
                      'rehash' to get table and field completion, but startup
                      and reconnecting may take a longer time. Disable with
                      --disable-auto-rehash.
                      (Defaults to on; use --skip-auto-rehash to disable.)
  -A, --no-auto-rehash
                      No automatic rehashing. One has to use 'rehash' to get
                      table and field completion. This gives a quicker start of
                      mysql and disables rehashing on reconnect.
  --auto-vertical-output
                      Automatically switch to vertical output mode if the
                      result is wider than the terminal width.
  -B, --batch         Don't use history file. Disable interactive behavior.
                      (Enables --silent.)

                      Directory for character set files.
  --column-type-info  Display column type information.
  -c, --comments      Preserve comments. Send comments to the server. The
                      default is --skip-comments (discard comments), enable
                      with --comments.
  -C, --compress      Use compression in server/client protocol.
  -#, --debug[=#]     This is a non-debug version. Catch this and exit.
  --debug-check       Check memory and open file usage at exit.
  -T, --debug-info    Print some debug info at exit.
  -D, --database=name Database to use.
  --default-character-set=name
                      Set the default character set.
  --delimiter=name    Delimiter to be used.
  -e, --execute=name  Execute command and quit. (Disables --force and history
                      file.)
  -E, --vertical      Print the output of a query (rows) vertically.
  -f, --force         Continue even if we get an SQL error. Sets
                      abort-source-on-error to 0
  -G, --named-commands
                      Enable named commands. Named commands mean this program's
                      internal commands; see mysql> help . When enabled, the
                      named commands can be used from any line of the query,
                      otherwise only from the first line, before an enter.
                      Disable with --disable-named-commands. This option is
                      disabled by default.
  -i, --ignore-spaces Ignore space after function names.
  --init-command=name SQL Command to execute when connecting to MySQL server.
                      Will automatically be re-executed when reconnecting.
  --local-infile      Enable/disable LOAD DATA LOCAL INFILE.
  -b, --no-beep       Turn off beep on error.
  -h, --host=name     Connect to host.

  --line-numbers      Write line numbers for errors.
                      (Defaults to on; use --skip-line-numbers to disable.)
  -L, --skip-line-numbers
                      Don't write line number for errors.
  -n, --unbuffered    Flush buffer after each query.

                      Don't write column names in results.
  --sigint-ignore     Ignore SIGINT (CTRL-C).
  -o, --one-database  Ignore statements except those that occur while the
                      default database is the one named at the command line.
  -p, --password[=name]
                      Password to use when connecting to server. If password is
                      not given it's asked from the tty.
  -W, --pipe          Use named pipes to connect to server.
  -P, --port=#        Port number to use for connection or 0 for default to, in
                      order of preference, my.cnf, $MYSQL_TCP_PORT,
                      /etc/services, built-in default (3306).
  --progress-reports  Get progress reports for long running commands (like
                      ALTER TABLE)
                      (Defaults to on; use --skip-progress-reports to disable.)
  --prompt=name       Set the mysql prompt to this value.
  --protocol=name     The protocol to use for connection (tcp, socket, pipe,
                      memory).
  -q, --quick         Don't cache result, print it row by row. This may slow
                      down the server if the output is suspended. Doesn't use
                      history file.
  -r, --raw           Write fields without conversion. Used with --batch.
  --reconnect         Reconnect if the connection is lost. Disable with
                      --disable-reconnect. This option is enabled by default.
                      (Defaults to on; use --skip-reconnect to disable.)
  -s, --silent        Be more silent. Print results with a tab as separator,
                      each row on new line.
  --shared-memory-base-name=name
                      Base name of shared memory.
  -S, --socket=name   The socket file to use for connection.
  --ssl               Enable SSL for connection (automatically enabled with
                      other flags).
  --ssl-ca=name       CA file in PEM format (check OpenSSL docs, implies
                      --ssl).
  --ssl-capath=name   CA directory (check OpenSSL docs, implies --ssl).
  --ssl-cert=name     X509 cert in PEM format (implies --ssl).
  --ssl-cipher=name   SSL cipher to use (implies --ssl).
  --ssl-key=name      X509 key in PEM format (implies --ssl).
  --ssl-crl=name      Certificate revocation list (implies --ssl).
  --ssl-crlpath=name  Certificate revocation list path (implies --ssl).

                      also. Does not work in batch mode. Disable with
                      --disable-tee. This option is disabled by default.
  -u, --user=name     User for login if not current user.
  -U, --safe-updates  Only allow UPDATE and DELETE that uses keys.
  -U, --i-am-a-dummy  Synonym for option --safe-updates, -U.
  -v, --verbose       Write more. (-v -v -v gives the table output format).
  -V, --version       Output version information and exit.
  -w, --wait          Wait and retry if connection is down.
  --connect-timeout=# Number of seconds before connection timeout.
  --max-allowed-packet=#
                      The maximum packet length to send to or receive from
                      server.
  --net-buffer-length=#
                      The buffer size for TCP/IP and socket communication.
  --select-limit=#    Automatic limit for SELECT when using --safe-updates.

                      --safe-updates.
  --secure-auth       Refuse client connecting to server if it uses old
                      (pre-4.1.1) protocol.

  --show-warnings     Show warnings after every statement.
  --plugin-dir=name   Directory for client-side plugins.
  --default-auth=name Default authentication client-side plugin to use.
  --binary-mode       By default, ASCII '\0' is disallowed and '\r\n' is
                      translated to '\n'. This switch turns off both features,
                      and also turns off parsing of all clientcommands except
                      \C and DELIMITER, in non-interactive mode (for input
                      piped to mysql or loaded using the 'source' command).
                      This is necessary when processing output from mysqlbinlog
                      that may contain blobs.

This will give you duplicate rows:

vocabulary[duplicated(vocabulary$id),]

This will give you the number of duplicates:

dim(vocabulary[duplicated(vocabulary$id),])[1]

Example:

vocabulary2 <-rbind(vocabulary,vocabulary[1,]) #creates a duplicate at the end
vocabulary2[duplicated(vocabulary2$id),]
#            id year    sex education vocabulary
#21639 20040001 2004 Female         9          3
dim(vocabulary2[duplicated(vocabulary2$id),])[1]
#[1] 1 #=1 duplicate

EDIT

OK, with the additional information, here's what you should do: duplicated has a fromLast option which allows you to get duplicates from the end. If you combine this with the normal duplicated, you get all duplicates. The following example adds duplicates to the original vocabulary object (line 1 is duplicated twice and line 5 is duplicated once). I then use table to get the total number of duplicates per ID.

#Create vocabulary object with duplicates
voc.dups <-rbind(vocabulary,vocabulary[1,],vocabulary[1,],vocabulary[5,])

#List duplicates
dups <-voc.dups[duplicated(voc.dups$id)|duplicated(voc.dups$id, fromLast=TRUE),]
dups
#            id year    sex education vocabulary
#1     20040001 2004 Female         9          3
#5     20040008 2004   Male        14          1
#21639 20040001 2004 Female         9          3
#21640 20040001 2004 Female         9          3
#51000 20040008 2004   Male        14          1

#Count duplicates by id
table(dups$id)
#20040001 20040008 
#       3        2 

git rm --cached file

You need a SMTP server to send your mail. If you have one available which does not require SMTP authentification (maybe your ISP's?) just edit the 'SMTP' ([mail function]) setting in your php.ini file.

If this is no option because your SMTP server requires authentification you won't be able to use the internal mail() function and have to use some 3rd party class which supports smtp auth. e.g. http://pear.php.net/package/Mail/

I could get solution for such a similar problem with addition of a simple line

HttpURLConnection hConn = (HttpURLConnection) url.openConnection();
hConn.setRequestMethod("HEAD");

My requirement was to know the response code and for that just getting the meta-information was sufficient, instead of getting the complete response body.

Default request method is GET and that was taking lot of time to return, finally throwing me SocketTimeoutException. The response was pretty fast when I set the Request Method to HEAD.

kennytm quoted man bash, but most of that is also POSIX 7: http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_07_04 :

The redirection operators "<<" and "<<-" both allow redirection of lines contained in a shell input file, known as a "here-document", to the input of a command.

The here-document shall be treated as a single word that begins after the next and continues until there is a line containing only the delimiter and a , with no characters in between. Then the next here-document starts, if there is one. The format is as follows:

[n]<<word
    here-document
delimiter

where the optional n represents the file descriptor number. If the number is omitted, the here-document refers to standard input (file descriptor 0).

If any character in word is quoted, the delimiter shall be formed by performing quote removal on word, and the here-document lines shall not be expanded. Otherwise, the delimiter shall be the word itself.

If no characters in word are quoted, all lines of the here-document shall be expanded for parameter expansion, command substitution, and arithmetic expansion. In this case, the in the input behaves as the inside double-quotes (see Double-Quotes). However, the double-quote character ( '"' ) shall not be treated specially within a here-document, except when the double-quote appears within "$()", "``", or "${}".

If the redirection symbol is "<<-", all leading <tab> characters shall be stripped from input lines and the line containing the trailing delimiter. If more than one "<<" or "<<-" operator is specified on a line, the here-document associated with the first operator shall be supplied first by the application and shall be read first by the shell.

When a here-document is read from a terminal device and the shell is interactive, it shall write the contents of the variable PS2, processed as described in Shell Variables, to standard error before reading each line of input until the delimiter has been recognized.

Examples

Some examples not yet given.

Quotes prevent parameter expansion

Without quotes:

a=0
cat <<EOF
$a
EOF

Output:

0

With quotes:

a=0
cat <<'EOF'
$a
EOF

or (ugly but valid):

a=0
cat <<E"O"F
$a
EOF

Outputs:

$a

Hyphen removes leading tabs

Without hyphen:

cat <<EOF
<tab>a
EOF

where <tab> is a literal tab, and can be inserted with Ctrl + V <tab>

Output:

<tab>a

With hyphen:

cat <<-EOF
<tab>a
<tab>EOF

Output:

a

This exists of course so that you can indent your cat like the surrounding code, which is easier to read and maintain. E.g.:

if true; then
    cat <<-EOF
    a
    EOF
fi

Unfortunately, this does not work for space characters: POSIX favored tab indentation here. Yikes.

One simple way using subplots:

import matplotlib.pyplot as plt

fig, axes = plt.subplots(3, 4, sharex=True, sharey=True)
# add a big axes, hide frame
fig.add_subplot(111, frameon=False)
# hide tick and tick label of the big axes
plt.tick_params(labelcolor='none', top=False, bottom=False, left=False, right=False)
plt.grid(False)
plt.xlabel("common X")
plt.ylabel("common Y")

You will have to split this into multiple statements. Here is one way to do that:

if (!obj.isPresent()) {
  logger.fatal("Object not available");
}

obj.ifPresent(o -> o.setAvailable(true));
return obj;

Another way (possibly over-engineered) is to use map:

if (!obj.isPresent()) {
  logger.fatal("Object not available");
}

return obj.map(o -> {o.setAvailable(true); return o;});

If obj.setAvailable conveniently returns obj, then you can simply the second example to:

if (!obj.isPresent()) {
  logger.fatal("Object not available");
}

return obj.map(o -> o.setAvailable(true));

just to toss it out for posterity: it can sometimes be preferable to generate a random string using an initial character set string. This is useful if the string is supposed to be entered manually by a human; excluding 0, O, 1, and l can help reduce user error.

var alpha = "abcdefghijkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ23456789"

// generates a random string of fixed size
func srand(size int) string {
    buf := make([]byte, size)
    for i := 0; i < size; i++ {
        buf[i] = alpha[rand.Intn(len(alpha))]
    }
    return string(buf)
}

and I typically set the seed inside of an init() block. They're documented here: http://golang.org/doc/effective_go.html#init

Use the hex code for a non-breaking space. Something like this:

.breadcrumbs a:before {
    content: '>\00a0';
}

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

function htmlDecode(t){
   if (t) return $('<div />').html(t).text();
}

works like a charm

The solutions offered here are quite bad.

1. You can't use regex, because that way, you search/highlight in the html tags.
2. You can't use regex, because it doesn't work properly with UTF* (anything with non-latin/English characters).
3. You can't just do an innerHTML.replace, because this doesn't work when the characters have a special HTML notation, e.g. & for &, < for <, > for >, ä for ä, ö for ö ü for ü ß for ß, etc.

What you need to do:

Loop through the HTML document, find all text nodes, get the textContent, get the position of the highlight-text with indexOf (with an optional toLowerCase if it should be case-insensitive), append everything before indexof as textNode, append the matched Text with a highlight span, and repeat for the rest of the textnode (the highlight string might occur multiple times in the textContent string).

Here is the code for this:

var InstantSearch = {

    "highlight": function (container, highlightText)
    {
        var internalHighlighter = function (options)
        {

            var id = {
                container: "container",
                tokens: "tokens",
                all: "all",
                token: "token",
                className: "className",
                sensitiveSearch: "sensitiveSearch"
            },
            tokens = options[id.tokens],
            allClassName = options[id.all][id.className],
            allSensitiveSearch = options[id.all][id.sensitiveSearch];


            function checkAndReplace(node, tokenArr, classNameAll, sensitiveSearchAll)
            {
                var nodeVal = node.nodeValue, parentNode = node.parentNode,
                    i, j, curToken, myToken, myClassName, mySensitiveSearch,
                    finalClassName, finalSensitiveSearch,
                    foundIndex, begin, matched, end,
                    textNode, span, isFirst;

                for (i = 0, j = tokenArr.length; i < j; i++)
                {
                    curToken = tokenArr[i];
                    myToken = curToken[id.token];
                    myClassName = curToken[id.className];
                    mySensitiveSearch = curToken[id.sensitiveSearch];

                    finalClassName = (classNameAll ? myClassName + " " + classNameAll : myClassName);

                    finalSensitiveSearch = (typeof sensitiveSearchAll !== "undefined" ? sensitiveSearchAll : mySensitiveSearch);

                    isFirst = true;
                    while (true)
                    {
                        if (finalSensitiveSearch)
                            foundIndex = nodeVal.indexOf(myToken);
                        else
                            foundIndex = nodeVal.toLowerCase().indexOf(myToken.toLowerCase());

                        if (foundIndex < 0)
                        {
                            if (isFirst)
                                break;

                            if (nodeVal)
                            {
                                textNode = document.createTextNode(nodeVal);
                                parentNode.insertBefore(textNode, node);
                            } // End if (nodeVal)

                            parentNode.removeChild(node);
                            break;
                        } // End if (foundIndex < 0)

                        isFirst = false;


                        begin = nodeVal.substring(0, foundIndex);
                        matched = nodeVal.substr(foundIndex, myToken.length);

                        if (begin)
                        {
                            textNode = document.createTextNode(begin);
                            parentNode.insertBefore(textNode, node);
                        } // End if (begin)

                        span = document.createElement("span");
                        span.className += finalClassName;
                        span.appendChild(document.createTextNode(matched));
                        parentNode.insertBefore(span, node);

                        nodeVal = nodeVal.substring(foundIndex + myToken.length);
                    } // Whend

                } // Next i 
            }; // End Function checkAndReplace 

            function iterator(p)
            {
                if (p === null) return;

                var children = Array.prototype.slice.call(p.childNodes), i, cur;

                if (children.length)
                {
                    for (i = 0; i < children.length; i++)
                    {
                        cur = children[i];
                        if (cur.nodeType === 3)
                        {
                            checkAndReplace(cur, tokens, allClassName, allSensitiveSearch);
                        }
                        else if (cur.nodeType === 1)
                        {
                            iterator(cur);
                        }
                    }
                }
            }; // End Function iterator

            iterator(options[id.container]);
        } // End Function highlighter
        ;


        internalHighlighter(
            {
                container: container
                , all:
                    {
                        className: "highlighter"
                    }
                , tokens: [
                    {
                        token: highlightText
                        , className: "highlight"
                        , sensitiveSearch: false
                    }
                ]
            }
        ); // End Call internalHighlighter 

    } // End Function highlight

};

Then you can use it like this:

function TestTextHighlighting(highlightText)
{
    var container = document.getElementById("testDocument");
    InstantSearch.highlight(container, highlightText);
}

Here's an example HTML document

<!DOCTYPE html>
<html>
    <head>
        <title>Example of Text Highlight</title>
        <style type="text/css" media="screen">
            .highlight{ background: #D3E18A;}
            .light{ background-color: yellow;}
        </style>
    </head>
    <body>
        <div id="testDocument">
            This is a test
            <span> This is another test</span>
            äöüÄÖÜäöüÄÖÜ
            <span>Test123&auml;&ouml;&uuml;&Auml;&Ouml;&Uuml;</span>
        </div>
    </body>
</html>

By the way, if you search in a database with LIKE,
e.g. WHERE textField LIKE CONCAT('%', @query, '%') [which you shouldn't do, you should use fulltext-search or Lucene], then you can escape every character with \ and add an SQL-escape-statement, that way you'll find special characters that are LIKE-expressions.

e.g.

WHERE textField LIKE CONCAT('%', @query, '%') ESCAPE '\'

and the value of @query is not '%completed%' but '%\c\o\m\p\l\e\t\e\d%'

(tested, works with SQL-Server and PostgreSQL, and every other RDBMS system that supports ESCAPE)

        sensitiveSearch: false
    }
]);


// highlighter.highlight(); // this would highlight in the entire table
// foreach tr - for each td2 
highlighter.highlightNode(td2); // this highlights in the second column of table

You can use lambda in Java 8

public static void main(String[] args) {
    tentimes(inputPrm - > System.out.println(inputPrm));
    //tentimes(System.out::println);  // You can also replace lambda with static method reference
}

public static void tentimes(Consumer myFunction) {
    for (int i = 0; i < 10; i++)
        myFunction.accept("hello");
}

This post is just to mention an additional option. In case you need to set custom R libs in your Linux shell script you may easily do so by

export R_LIBS="~/R/lib"

See R admin guide on complete list of options.

Recently, I have faced this issue. And fixed it by changing CPU/ABI from Intel Atom (x86) to ARM(armeabi-v7a).

• Select the Virtual Device. Click on Edit
• Click on CPU/ABI option
• Change it to ARM(armeabi-v7a) from intel. Click OK

Job done.

#define GENERAL__GET_BITS_FROM_U8(source,lsb,msb) \
    ((uint8_t)((source) & \
        ((uint8_t)(((uint8_t)(0xFF >> ((uint8_t)(7-((uint8_t)(msb) & 7))))) & \
             ((uint8_t)(0xFF << ((uint8_t)(lsb) & 7)))))))

#define GENERAL__GET_BITS_FROM_U16(source,lsb,msb) \
    ((uint16_t)((source) & \
        ((uint16_t)(((uint16_t)(0xFFFF >> ((uint8_t)(15-((uint8_t)(msb) & 15))))) & \
            ((uint16_t)(0xFFFF << ((uint8_t)(lsb) & 15)))))))

#define GENERAL__GET_BITS_FROM_U32(source,lsb,msb) \
    ((uint32_t)((source) & \
        ((uint32_t)(((uint32_t)(0xFFFFFFFF >> ((uint8_t)(31-((uint8_t)(msb) & 31))))) & \
            ((uint32_t)(0xFFFFFFFF << ((uint8_t)(lsb) & 31)))))))

The default timeout is defined by default_socket_timeout ini-setting, which is 60 seconds. You can also change it on the fly:

ini_set('default_socket_timeout', 900); // 900 Seconds = 15 Minutes

Another way to set a timeout, would be to use stream_context_create to set the timeout as HTTP context options of the HTTP stream wrapper in use:

$ctx = stream_context_create(array('http'=>
    array(
        'timeout' => 1200,  //1200 Seconds is 20 Minutes
    )
));

echo file_get_contents('http://example.com/', false, $ctx);

var result = from x in entity
   join y in entity2 on new { x.field1, x.field2 } equals new { y.field1, y.field2 }

Since PikkuKatja and glallen asked for a more general solution and I cannot comment yet, I'll write an answer. You can combine statements as in:

> df[df=="" | df==12] <- NA
> df
     A    B
1  <NA> <NA>
2  xyz  <NA>
3  jkl  100

For factors, zxzak's code already yields factors:

> df <- data.frame(list(A=c("","xyz","jkl"), B=c(12,"",100)))
> str(df)
'data.frame':   3 obs. of  2 variables:
 $ A: Factor w/ 3 levels "","jkl","xyz": 1 3 2
 $ B: Factor w/ 3 levels "","100","12": 3 1 2

If in trouble, I'd suggest to temporarily drop the factors.

df[] <- lapply(df, as.character)

It means that you compiled your classes under a specific JDK, but then try to run them under older version of JDK.

All the answers above rewrite the history of the repository. As long as the name to change has not been used by multiple authors and especially if the repository has been shared and the commit is old I'd prefer to use .mailmap, documented at https://git-scm.com/docs/git-shortlog. It allows mapping incorrect names/emails to the correct one without modifying the repo history. You can use lines like:

Proper Name <[email protected]> <root@localhost>

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

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

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

Super simple answer - solved!

my full answer here it is now built in in some oracle versions.

select group_id, 
regexp_replace(
    listagg(name, ',') within group (order by name)
    ,'([^,]+)(,\1)*(,|$)', '\1\3')
from demotable
group by group_id;  

This only works if you specify the delimiter to ',' not ', ' ie works only for no spaces after the comma. If you want spaces after the comma - here is a example how.

select 
replace(
    regexp_replace(
     regexp_replace('BBall, BBall, BBall, Football, Ice Hockey ',',\s*',',')            
    ,'([^,]+)(,\1)*(,|$)', '\1\3')
,',',', ') 
from dual

gives BBall, Football, Ice Hockey

i really disadvise you against using Thread.Sleep(2000), because of a several reasons (a few are described here), but most of all because its not useful when it comes to debugging/testing.

I recommend to use a C# Timer instead of Thread.Sleep(). Timers let you perform methods frequently (if necessary) AND are much easiert to use in testing! There's a very nice example of how to use a timer right behind the hyperlink - just put your logic "what happens after 2 seconds" right into the Timer.Elapsed += new ElapsedEventHandler(OnTimedEvent); method.

To restart a running service:

net stop "service name" && net start "service name"

However, if you don't know if the service is running in the first place and want to restart or start it, use this:

net stop "service name" & net start "service name"

This works if the service is already running or not.

For reference, here is the documentation on conditional processing symbols.

1.- Export signed packages:

• Use the Extract a Signed Android Application Package Wizard (On the main menu, choose Build | Generate Signed APK). The package will be signed during extraction.

  OR

• Configure the .apk file as an artifact by creating an artifact definition of the type Android application with the Release signed package mode.

2.- Export unsigned packages: this can only be done through artifact definitions with the Debug or Release unsigned package mode specified.

In simple, Normalisation is Reduction of Redundancies.
Examples of Redundancies:
a) white spaces outside of the root/document tags(...<document></document>...)
b) white spaces within start tag (<...>) and end tag (</...>)
c) white spaces between attributes and their values (ie. spaces between key name and =")
d) superfluous namespace declarations
e) line breaks/white spaces in texts of attributes and tags
f) comments etc...

Here's a working example to send plain text and HTML emails from Python using smtplib along with the CC and BCC options.

https://varunver.wordpress.com/2017/01/26/python-smtplib-send-plaintext-and-html-emails/

#!/usr/bin/env python
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

def send_mail(params, type_):
      email_subject = params['email_subject']
      email_from = "[email protected]"
      email_to = params['email_to']
      email_cc = params.get('email_cc')
      email_bcc = params.get('email_bcc')
      email_body = params['email_body']

      msg = MIMEMultipart('alternative')
      msg['To'] = email_to
      msg['CC'] = email_cc
      msg['Subject'] = email_subject
      mt_html = MIMEText(email_body, type_)
      msg.attach(mt_html)

      server = smtplib.SMTP('YOUR_MAIL_SERVER.DOMAIN.COM')
      server.set_debuglevel(1)
      toaddrs = [email_to] + [email_cc] + [email_bcc]
      server.sendmail(email_from, toaddrs, msg.as_string())
      server.quit()

# Calling the mailer functions
params = {
    'email_to': '[email protected]',
    'email_cc': '[email protected]',
    'email_bcc': '[email protected]',
    'email_subject': 'Test message from python library',
    'email_body': '<h1>Hello World</h1>'
}
for t in ['plain', 'html']:
    send_mail(params, t)

Step 1: Ensure spawn is called the right way

First, review the docs for child_process.spawn( command, args, options ):

Launches a new process with the given command, with command line arguments in args. If omitted, args defaults to an empty Array.

The third argument is used to specify additional options, which defaults to:

{ cwd: undefined, env: process.env }

Use env to specify environment variables that will be visible to the new process, the default is process.env.

Ensure you are not putting any command line arguments in command and the whole spawn call is valid. Proceed to next step.

Step 2: Identify the Event Emitter that emits the error event

Search on your source code for each call to spawn, or child_process.spawn, i.e.

spawn('some-command', [ '--help' ]);

and attach there an event listener for the 'error' event, so you get noticed the exact Event Emitter that is throwing it as 'Unhandled'. After debugging, that handler can be removed.

spawn('some-command', [ '--help' ])
  .on('error', function( err ){ throw err })
;

Execute and you should get the file path and line number where your 'error' listener was registered. Something like:

/file/that/registers/the/error/listener.js:29
      throw err;
            ^
Error: spawn ENOENT
    at errnoException (child_process.js:1000:11)
    at Process.ChildProcess._handle.onexit (child_process.js:791:34)

If the first two lines are still

events.js:72
        throw er; // Unhandled 'error' event

do this step again until they are not. You must identify the listener that emits the error before going on next step.

Step 3: Ensure the environment variable $PATH is set

There are two possible scenarios:

1. You rely on the default spawn behaviour, so child process environment will be the same as process.env.
2. You are explicity passing an env object to spawn on the options argument.

In both scenarios, you must inspect the PATH key on the environment object that the spawned child process will use.

Example for scenario 1

// inspect the PATH key on process.env
console.log( process.env.PATH );
spawn('some-command', ['--help']);

Example for scenario 2

var env = getEnvKeyValuePairsSomeHow();
// inspect the PATH key on the env object
console.log( env.PATH );
spawn('some-command', ['--help'], { env: env });

The absence of PATH (i.e., it's undefined) will cause spawn to emit the ENOENT error, as it will not be possible to locate any command unless it's an absolute path to the executable file.

When PATH is correctly set, proceed to next step. It should be a directory, or a list of directories. Last case is the usual.

Step 4: Ensure command exists on a directory of those defined in PATH

Spawn may emit the ENOENT error if the filename command (i.e, 'some-command') does not exist in at least one of the directories defined on PATH.

Locate the exact place of command. On most linux distributions, this can be done from a terminal with the which command. It will tell you the absolute path to the executable file (like above), or tell if it's not found.

Example usage of which and its output when a command is found

> which some-command
some-command is /usr/bin/some-command

Example usage of which and its output when a command is not found

> which some-command
bash: type: some-command: not found

miss-installed programs are the most common cause for a not found command. Refer to each command documentation if needed and install it.

When command is a simple script file ensure it's accessible from a directory on the PATH. If it's not, either move it to one or make a link to it.

Once you determine PATH is correctly set and command is accessible from it, you should be able to spawn your child process without spawn ENOENT being thrown.

I follow all recommendations and all requirements. I install my self signed root CA on my iPhone. I make it trusted. I put certificate signed with this root CA on my local development server and I still get certificated error on safari iOS. Working on all other platforms.

You are missing setter for salt property as indicated by the exception

Please add the setter as

In xaml

<TextBlock Text="{Binding CelsiusTemp}" />

In ViewModel, this way setting the value also works:

 public string CelsiusTemp
        {
            get { return string.Format("{0}°C", _CelsiusTemp); }
            set
            {
                value = value.Replace("°C", "");
              _CelsiusTemp = value;
            }
        }

you can round your double and cast ist:

(int)Math.Round(myDouble);

According https://apiblueprint.org/documentation/examples/13-named-endpoints.html is a resource a "general" place of storage of the given entity - e.g. /customers/30654/orders, whereas an endpoint is the concrete action (HTTP Method) over the given resource. So one resource can have multiple endpoints.

Just a VB.NET version of the answer:

Private Function GetRequestIpAddress() As IPAddress
    Dim serverVariables = HttpContext.Current.Request.ServerVariables
    Dim headersKeysToCheck = {"HTTP_CLIENT_IP", _
                              "HTTP_X_FORWARDED_FOR", _
                              "HTTP_X_FORWARDED", _
                              "HTTP_X_CLUSTER_CLIENT_IP", _
                              "HTTP_FORWARDED_FOR", _
                              "HTTP_FORWARDED", _
                              "REMOTE_ADDR"}
    For Each thisHeaderKey In headersKeysToCheck
        Dim thisValue = serverVariables.Item(thisHeaderKey)
        If thisValue IsNot Nothing Then
            Dim validAddress As IPAddress = Nothing
            If IPAddress.TryParse(thisValue, validAddress) Then
                Return validAddress
            End If
        End If
    Next
    Return Nothing
End Function

Here is another solution, which is more general than the others -- it supports splitting output (written to sys.stdout) to any number of file-like objects. There's no requirement that __stdout__ itself is included.

import sys

class multifile(object):
    def __init__(self, files):
        self._files = files
    def __getattr__(self, attr, *args):
        return self._wrap(attr, *args)
    def _wrap(self, attr, *args):
        def g(*a, **kw):
            for f in self._files:
                res = getattr(f, attr, *args)(*a, **kw)
            return res
        return g

# for a tee-like behavior, use like this:
sys.stdout = multifile([ sys.stdout, open('myfile.txt', 'w') ])

# all these forms work:
print 'abc'
print >>sys.stdout, 'line2'
sys.stdout.write('line3\n')

NOTE: This is a proof-of-concept. The implementation here is not complete, as it only wraps methods of the file-like objects (e.g. write), leaving out members/properties/setattr, etc. However, it is probably good enough for most people as it currently stands.

What I like about it, other than its generality, is that it is clean in the sense it doesn't make any direct calls to write, flush, os.dup2, etc.

By selecting 'Class Library' you were accidentally telling it to make a .Net Library using the CLI (managed) extenstion of C++.

Instead, create a Win32 project, and in the Application Settings on the next page, choose 'DLL'.

You can also make an MFC DLL or ATL DLL from those library choices if you want to go that route, but it sounds like you don't.

You say you have a database on PhpMyAdmin, so you are using MySQL. PHP provides functions for connecting to a MySQL database.

$connection = mysql_connect('localhost', 'root', ''); //The Blank string is the password
mysql_select_db('hrmwaitrose');

$query = "SELECT * FROM employee"; //You don't need a ; like you do in SQL
$result = mysql_query($query);

echo "<table>"; // start a table tag in the HTML

while($row = mysql_fetch_array($result)){   //Creates a loop to loop through results
echo "<tr><td>" . $row['name'] . "</td><td>" . $row['age'] . "</td></tr>";  //$row['index'] the index here is a field name
}

echo "</table>"; //Close the table in HTML

mysql_close(); //Make sure to close out the database connection

In the while loop (which runs every time we encounter a result row), we echo which creates a new table row. I also add a to contain the fields.

This is a very basic template. You see the other answers using mysqli_connect instead of mysql_connect. mysqli stands for mysql improved. It offers a better range of features. You notice it is also a little bit more complex. It depends on what you need.

1. Project > Generate Javadoc....

2. In the Javadoc command: field, browse to find javadoc.exe (usually at [path_to_jdk_directory]\bin\javadoc.exe).

3. Check the box next to the project/package/file for which you are creating the Javadoc.

4. In the Destination: field, browse to find the desired destination (for example, the root directory of the current project).

5. Click Finish.

You should now be able to find the newly generated Javadoc in the destination folder. Open index.html.

Swift 5: Use following code

extension Double {

    func getStringValue(withFloatingPoints points: Int = 0) -> String {
        let valDouble = modf(self)
        let fractionalVal = (valDouble.1)
        if fractionalVal > 0 {
            return String(format: "%.*f", points, self)
        }
        return String(format: "%.0f", self)
    }
}

I'd like to add my Python3 answer for completeness:

from io import BytesIO
from zipfile import ZipFile
import requests

def get_zip(file_url):
    url = requests.get(file_url)
    zipfile = ZipFile(BytesIO(url.content))
    zip_names = zipfile.namelist()
    if len(zip_names) == 1:
        file_name = zip_names.pop()
        extracted_file = zipfile.open(file_name)
        return extracted_file
    return [zipfile.open(file_name) for file_name in zip_names]

IMHO you could just send the JSON encoded (ie. encodeURIComponent) in the URL, this way you do not violate the HTTP specs and get your JSON to the server.

It cannot be done. It is impossible.

This query seems to do the trick:

SELECT 
    sys.objects.name AS table_name, 
    sys.columns.name AS column_name
FROM sys.columns JOIN sys.objects 
    ON sys.columns.object_id=sys.objects.object_id
WHERE 
    sys.columns.is_identity=1
    AND
    sys.objects.type in (N'U')

you can use code below in layout

android:textCursorDrawable="@color/red"
        android:textColor="@color/black

To delete all stashes older than 40 days, use:

git reflog expire --expire-unreachable=40.days refs/stash

Add --dry-run to see which stashes are deleted.

See https://stackoverflow.com/a/44829516/946850 for an explanation and much more detail.

encodeURIComponent(JSON.stringify(object_to_be_serialised))

spring data save() method will help you to perform both: adding new item and updating an existed item.

Just call the save() and enjoy the life :))

You could also organise them into modules. So it would be something like.

./
controllers
    index.js
    indexController.js
app.js

and then in the indexController.js of the controllers export your controllers.

//indexController.js
module.exports = function(){
//do some set up

var self = {
     indexAction : function (req,res){
       //do your thing
}
return self;
};

then in index.js of controllers dir

exports.indexController = require("./indexController");

and finally in app.js

var controllers = require("./controllers");

app.get("/",controllers.indexController().indexAction);

I think this approach allows for clearer seperation and also you can configure your controllers by passing perhaps a db connection in.

The easiest solution is to dispense with "like" altogether:

Select * 
from table
where charindex(search_criteria, name) > 0

I prefer charindex over like. Historically, it had better performance, but I'm not sure if it makes much of difference now.

Create file .flaskenv in the project root directory.

The parameters in this file are typically:

FLASK_APP=app.py
FLASK_ENV=development
FLASK_RUN_HOST=[dev-host-ip]
FLASK_RUN_PORT=5000

If you have a virtual environment, activate it and do a pip install python-dotenv .

This package is going to use the .flaskenv file, and declarations inside it will be automatically imported across terminal sessions.

Then you can do flask run

Today I ran into the exact same problem while working on a progressive web app (PWA) page and deleting some cache and service worker data for that page from Firefox. The dev console reported that none of the 4 Javascript files on the page would load anymore. The problem persisted in Safe mode, so it was not an add-on issue. The same script files loaded fine from other web pages on the same website. No amount of clearing the Firefox cache or wiping web page data from Firefox would help, nor would rebooting the Windows 10 PC. Chrome all the time worked fine on the problem page. In the end I did a restore of the entire Firefox profile folder from a day-old backup, and the problem was immediately gone, so it was not a problem with my PWA app. Apparently something in Firefox got corrupted.

A possible solution would be to check your proxy settings; under Windows 7 you can find those settings in the other.xml file present under the path C:\Users\YourUsername\\.AndroidStudio\config\options.

Note that if you turn both options "USE_HTTP_PROXY" and "USE_PROXY_PAC" to true the error keep coming but a pop-up should come out noticing the problem of a double configuration and prompting a resolution with a input window for those settings.

UPDATE - Possible solution

I've just managed to complete the wizard at home, maybe the proxy is not the real problem (as the last comment of @meanderingmoose pointed out). It seems there is a problem with the default installer of Android Studio 1.0.0, the one that contain both the IDE and di SDK Tools: the default installation path for the android sdk tools ends with myInstallPath../sdk/android-sdk but the first run setting for the Android Studio points at ..myInstallPath../sdk. So here is what i did.

• Cut & Paste the content of the android-sdk folder outside the folder, so the files are under ..myInstallPath../sdk/
• Use SDK Manager from the new location to update everything (Use this instead of the automatic wizard, you can select which package you want or need and you get also the speed and estimate time for the download)
• Run Android Studio (it should load and check that the SDK is up to date and start the creation of an AVD, after that the IDE will load completely)

UPDATE - Workaround for the "download interrupted: read timed out" problem

The firewall and the proxy prevented my SDK Manager to download some updates, so i've recovered the .xml url for these updates, searched for the .zip files i needed and directly downloaded them with the help of a download manager, then i've manually installed them in their relative folder under the sdk folder ..a bit tricky but worked for me. For example in the Addon_xml_file i've searched for the m2repository, found the entry and downloaded the archive with the link m2repository_r14_zip_file. You always find the files you need in the same base as the .xml file (take a look at the url i've posted for the example).

my css

TR.gray-t {background:#949494;}
h3{
    padding-top:3px;
    font:bold 12px/2px Arial;
}

my html

<TR class='gray-t'>
<TD colspan='3'><h3>KAJANG</h3>

I decrease the 2nd size in font.

padding-top is used to fix the size in IE7.

You need to add parentheses after a method call, else the compiler will think you're talking about the method itself (a delegate type), whereas you're actually talking about the return value of that method.

string t = obj.getTitle();

Extra Non-Essential Information

Also, have a look at properties. That way you could use title as if it were a variable, while, internally, it works like a function. That way you don't have to write the functions getTitle() and setTitle(string value), but you could do it like this:

public string Title // Note: public fields, methods and properties use PascalCasing
{
    get // This replaces your getTitle method
    {
        return _title; // Where _title is a field somewhere
    }
    set // And this replaces your setTitle method
    {
        _title = value; // value behaves like a method parameter
    }
}

Or you could use auto-implemented properties, which would use this by default:

public string Title { get; set; }

And you wouldn't have to create your own backing field (_title), the compiler would create it itself.

Also, you can change access levels for property accessors (getters and setters):

public string Title { get; private set; }

You use properties as if they were fields, i.e.:

this.Title = "Example";
string local = this.Title;

In the neural network terminology:

• one epoch = one forward pass and one backward pass of all the training examples
• batch size = the number of training examples in one forward/backward pass. The higher the batch size, the more memory space you'll need.
• number of iterations = number of passes, each pass using [batch size] number of examples. To be clear, one pass = one forward pass + one backward pass (we do not count the forward pass and backward pass as two different passes).

Example: if you have 1000 training examples, and your batch size is 500, then it will take 2 iterations to complete 1 epoch.

FYI: Tradeoff batch size vs. number of iterations to train a neural network

The term "batch" is ambiguous: some people use it to designate the entire training set, and some people use it to refer to the number of training examples in one forward/backward pass (as I did in this answer). To avoid that ambiguity and make clear that batch corresponds to the number of training examples in one forward/backward pass, one can use the term mini-batch.

1. Add an exit handler that closes all the bars.
2. __del__() gets called when the number of references to an object hits 0 while the VM is still running. This may be caused by the GC.
3. If __init__() raises an exception then the object is assumed to be incomplete and __del__() won't be invoked.

In windows XP and later, there's a command: tasklist that lists all process id's.

You can execute OS-commands in Java by:

Runtime.getRuntime().exec("your command here");

If you need to handle the output of a command, see example: using Runtime.exec() in Java

Post build event for Visual Studio

echo  >RevisionNumber.cs static class Git { public static int RevisionNumber =
git  >>RevisionNumber.cs rev-list --count HEAD
echo >>RevisionNumber.cs ; }

Just test if the array is empty.

$.getJSON(url,function(json){
    if ( json.length == 0 ) {
        console.log("NO DATA!")
    }
});

When you type x = 0 that is creating a new int variable (name) and assigning a zero to it.

When you type x[age1] that is trying to access the age1'th entry, as if x were an array.

Alternatively you can grant the user DROP_ANY_TABLE privilege if need be and the procedure will run as is without the need for any alteration. Dangerous maybe but depends what you're doing :)

To remove all child elements from your div:

$('#mysweetdiv').empty();

.removeData() and the corresponding .data() function are used to attach data behind an element, say if you wanted to note that a specific list element referred to user ID 25 in your database:

var $li = $('<li>Joe</li>').data('id', 25);

I am new to Python, started yesterday (though I have been programming for 45 years).

I came here because I was writing a function where I wanted to have two so called out-parameters. If it would have been only one out-parameter, I wouldn't get hung up right now on checking how reference/value works in Python. I would just have used the return value of the function instead. But since I needed two such out-parameters I felt I needed to sort it out.

In this post I am going to show how I solved my situation. Perhaps others coming here can find it valuable, even though it is not exactly an answer to the topic question. Experienced Python programmers of course already know about the solution I used, but it was new to me.

From the answers here I could quickly see that Python works a bit like Javascript in this regard, and that you need to use workarounds if you want the reference functionality.

But then I found something neat in Python that I don't think I have seen in other languages before, namely that you can return more than one value from a function, in a simple comma separated way, like this:

def somefunction(p):
    a=p+1
    b=p+2
    c=-p
    return a, b, c

and that you can handle that on the calling side similarly, like this

x, y, z = somefunction(w)

That was good enough for me and I was satisfied. No need to use some workaround.

In other languages you can of course also return many values, but then usually in the from of an object, and you need to adjust the calling side accordingly.

The Python way of doing it was nice and simple.

If you want to mimic by reference even more, you could do as follows:

def somefunction(a, b, c):
    a = a * 2
    b = b + a
    c = a * b * c
    return a, b, c

x = 3
y = 5
z = 10
print(F"Before : {x}, {y}, {z}")

x, y, z = somefunction(x, y, z)

print(F"After  : {x}, {y}, {z}")

which gives this result

Before : 3, 5, 10  
After  : 6, 11, 660

If you are using git, you can add *.swp to .gitignore.

Its so simple just use this

Its working fine for me

each JSF component renders itself out to HTML and has complete control over what HTML it produces. There are many tricks that can be used by JSF, and exactly which of those tricks will be used depends on the JSF implementation you are using.

• Ensure that every from input has a totaly unique name, so that when the form gets submitted back to to component tree that rendered it, it is easy to tell where each component can read its value form.
• The JSF component can generate javascript that submitts back to the serer, the generated javascript knows where each component is bound too, because it was generated by the component.

• For things like hlink you can include binding information in the url as query params or as part of the url itself or as matrx parameters. for examples.

  http:..../somelink?componentId=123 would allow jsf to look in the component tree to see that link 123 was clicked. or it could e htp:..../jsf;LinkId=123

The easiest way to answer this question is to create a JSF page with only one link, then examine the html output it produces. That way you will know exactly how this happens using the version of JSF that you are using.

My way of Insert in SQL Server. Also I usually check if a temporary table exists.

It is best to use two DateTimePickers for the Job One will be the default for the date section and the second DateTimePicker is for the time portion. Format the second DateTimePicker as follows.

      timePortionDateTimePicker.Format = DateTimePickerFormat.Time;
      timePortionDateTimePicker.ShowUpDown = true;

The Two should look like this after you capture them

To get the DateTime from both these controls use the following code

DateTime myDate = datePortionDateTimePicker.Value.Date + 
                    timePortionDateTimePicker.Value.TimeOfDay; 

To assign the DateTime to both these controls use the following code

datePortionDateTimePicker.Value  = myDate.Date;  
timePortionDateTimePicker.Value  = myDate.TimeOfDay; 

you can do it like this for multiple order by

IOrderedEnumerable<JToken> sort;
                        if (query.OrderBys[0].IsDESC)
                        {
                            sort = jarry.OrderByDescending(r => (string)r[query.OrderBys[0].Key]);
                        }
                        else
                        {
                            sort = jarry.OrderBy(r =>
                                (string) r[query.OrderBys[0].Key]); 
                        }
                        foreach (var item in query.OrderBys.Skip(1))
                        {
                            if (item.IsDESC)
                            {
                                sort = sort.ThenByDescending(r => (string)r[item.Key]);
                            }
                            else
                            {
                                sort = sort.ThenBy(r => (string)r[item.Key]);
                            }

The Problem is related to MySql Driver

Class.forName("com.mysql.jdbc.Driver");

Add the MySQL jdbc driver jar file in to your classpath.

Also i have this error on JDK. I build the ClassPath Properly then I put the "mysql-connector-java-5.1.25-bin" in dir "C:\Program Files\Java\jre7\lib\ext" in this dir i have my JDK. then compile and Run again then it's working fine.

You can use 'onclick' attribute like this :

<a ... href="javascript: onclick();" ...>...</a>

I think if you just bubble an exception, it should be handled in the jQuery callback that is passed in for the 'error' option. (We also log this exception on the server side to a central log). No special HTTP error code required, but I'm curious to see what other folks do, too.

This is what I do, but that's just my $.02

If you are going to be RESTful and return error codes, try to stick to the standard codes set forth by the W3C: http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

You may be interested in realpath(3), or Python's os.path.realpath. The two aren't exactly the same; the C library call requires that intermediary path components exist, while the Python version does not.

$ pwd
/tmp/foo
$ ls -l
total 16
-rw-r--r--  1 miles    wheel  0 Jul 11 21:08 a
lrwxr-xr-x  1 miles    wheel  1 Jul 11 20:49 b -> a
lrwxr-xr-x  1 miles    wheel  1 Jul 11 20:49 c -> b
$ python -c 'import os,sys;print(os.path.realpath(sys.argv[1]))' c

I know you said you'd prefer something more lightweight than another scripting language, but just in case compiling a binary is insufferable, you can use Python and ctypes (available on Mac OS X 10.5) to wrap the library call:

#!/usr/bin/python

import ctypes, sys

libc = ctypes.CDLL('libc.dylib')
libc.realpath.restype = ctypes.c_char_p
libc.__error.restype = ctypes.POINTER(ctypes.c_int)
libc.strerror.restype = ctypes.c_char_p

def realpath(path):
    buffer = ctypes.create_string_buffer(1024) # PATH_MAX
    if libc.realpath(path, buffer):
        return buffer.value
    else:
        errno = libc.__error().contents.value
        raise OSError(errno, "%s: %s" % (libc.strerror(errno), buffer.value))

if __name__ == '__main__':
    print realpath(sys.argv[1])

Ironically, the C version of this script ought to be shorter. :)

If you want to pass a parameter to the delayed function:

    setTimeout(setTimer, 3000, param1, param2);

They're not recommended because it's a PITA if you ever have to move your code to a server where it's not supported (and you can't enable it). As you say, lots of shared hosts do support shorttags but "lots" isn't all of them. If you want to share your scripts, it's best to use the full syntax.

I agree that <? and <?= are easier on programmers than <?php and <?php echo but it is possible to do a bulk find-and-replace as long as you use the same form each time (and don't chuck in spaces (eg: <? php or <? =)

I don't buy readability as a reason at all. Most serious developers have the option of syntax highlighting available to them.

As ThiefMaster mentions in the comments, as of PHP 5.4, <?= ... ?> tags are supported everywhere, regardless of shorttags settings. This should mean they're safe to use in portable code but that does mean there's then a dependency on PHP 5.4+. If you want to support pre-5.4 and can't guarantee shorttags, you'll still need to use <?php echo ... ?>.

Also, you need to know that ASP tags <% , %> , <%= , and script tag are removed from PHP 7. So if you would like to support long-term portable code and would like switching to the most modern tools consider changing that parts of code.

I ran into this recently. Our organization restricts the accounts that run application pools to a select list of servers in Active Directory. I found that I had not added one of the machines hosting the application to the "Log On To" list for the account in AD.

Let's give an example for int(10) one with zerofill keyword, one not, the table likes that:

create table tb_test_int_type(
    int_10 int(10),
    int_10_with_zf int(10) zerofill,
    unit int unsigned
);

Let's insert some data:

insert into tb_test_int_type(int_10, int_10_with_zf, unit)
values (123456, 123456,3147483647), (123456, 4294967291,3147483647) 
;

Then

select * from tb_test_int_type; 

# int_10, int_10_with_zf, unit
'123456', '0000123456', '3147483647'
'123456', '4294967291', '3147483647'

We can see that

• with keyword zerofill, num less than 10 will fill 0, but without zerofill it won't

• Secondly with keyword zerofill, int_10_with_zf becomes unsigned int type, if you insert a minus you will get error Out of range value for column...... But you can insert minus to int_10. Also if you insert 4294967291 to int_10 you will get error Out of range value for column.....

Conclusion:

1. int(X) without keyword zerofill, is equal to int range -2147483648~2147483647

2. int(X) with keyword zerofill, the field is equal to unsigned int range 0~4294967295, if num's length is less than X it will fill 0 to the left

The Stack is an area of memory for keeping temporary data. Stack is used by the CALL instruction to keep the return address for procedures The return RET instruction gets this value from the stack and returns to that offset. The same thing happens when an INT instruction calls an interrupt. It stores in the Stack the flag register, code segment and offset. The IRET instruction is used to return from interrupt call.

The Stack is a Last In First Out (LIFO) memory. Data is placed onto the Stack with a PUSH instruction and removed with a POP instruction. The Stack memory is maintained by two registers: the Stack Pointer (SP) and the Stack Segment (SS) register. When a word of data is PUSHED onto the stack the the High order 8-bit Byte is placed in location SP-1 and the Low 8-bit Byte is placed in location SP-2. The SP is then decremented by 2. The SP addds to the (SS x 10H) register, to form the physical stack memory address. The reverse sequence occurs when data is POPPED from the Stack. When a word of data is POPPED from the stack the the High order 8-bit Byte is obtained in location SP-1 and the Low 8-bit Byte is obtained in location SP-2. The SP is then incremented by 2.

Where did you put the code in?

I try your code in my demo, I found out, if you put the code in

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { 

will fail, because key window have been setting yet.

But I put your code in some view controller's

override func viewDidLoad() {

It just works.

Per the current docs, https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-bulk.html:

If you’re providing text file input to curl, you must use the --data-binary flag instead of plain -d. The latter doesn’t preserve newlines.

Example:

$ curl -s -XPOST localhost:9200/_bulk --data-binary @requests

function trimRegex(str, regex){
    return str.substr(str.match(regex).index).split('').reverse().join('').substr(str.match(regex).index).split('').reverse().join('');
}

let test = '||ab||cd||';
trimRegex(test, /[^|]/);
console.log(test); //output: ab||cd

or

function trimChar(str, trim, req){
    let regex = new RegExp('[^'+trim+']');
    return str.substr(str.match(regex).index).split('').reverse().join('').substr(str.match(regex).index).split('').reverse().join('');
}

let test = '||ab||cd||';
trimChar(test, '|');
console.log(test); //output: ab||cd

You don't mention if the columns are nullable. If they are and you want the same semantics that the AVG aggregate provides you can do (2008)

SELECT *,
       (SELECT AVG(c)
        FROM   (VALUES(R1),
                      (R2),
                      (R3),
                      (R4),
                      (R5)) T (c)) AS [Average]
FROM   Request  

The 2005 version is a bit more tedious

SELECT *,
       (SELECT AVG(c)
        FROM   (SELECT R1
                UNION ALL
                SELECT R2
                UNION ALL
                SELECT R3
                UNION ALL
                SELECT R4
                UNION ALL
                SELECT R5) T (c)) AS [Average]
FROM   Request

Not trying to be smart about it, but if you use Sublime Text for your editor, the steps are:

1. Select the block
2. cmd+/ on Mac or ctrl+/ on Linux & Windows
3. Profit

I'd imagine that other editors have similar functionality too. Which one are you using? I'd be happy to do some digging.

I have seen comments in INI files, so yes. Please refer to this Wikipedia article. I could not find an official specification, but that is the correct syntax for comments, as many game INI files had this as I remember.

Edit

The API returns the Value and the Comment (forgot to mention this in my reply), just construct and example INI file and call the API on this (with comments) and you can see how this is returned.

Another way, using cut instead of sed.

result=`echo $pid | cut -c 5-`

They are very similar but not really the same.

In terms of efficiency, I've found the left join is null statement more efficient (when an abundance of rows are to be selected that is)

Similar as they are, merge! and store treat existing hashes differently depending on keynames, and will therefore affect your preference. Other than that from a syntax standpoint, merge!'s key: "value" syntax closely matches up against JavaScript and Python. I've always hated comma-separating key-value pairs, personally.

hash = {}
hash.merge!(key: "value")
hash.merge!(:key => "value")
puts hash

{:key=>"value"}

hash = {}
hash.store(:key, "value")
hash.store("key", "value")
puts hash

{:key=>"value", "key"=>"value"}

To get the shovel operator << working, I would advise using Mark Thomas's answer.

The simplest solution:

List<String> list = Files.readAllLines(Paths.get("path/of/text"), StandardCharsets.UTF_8);
String[] a = list.toArray(new String[list.size()]); 

Note that java.nio.file.Files is since 1.7

Try This it worked like a charm for me,

Objective C

I have set RGB gradient background Color to UIview

   UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,35)];
   CAGradientLayer *gradient = [CAGradientLayer layer];
   gradient.frame = view.bounds;
   gradient.startPoint = CGPointZero;
   gradient.endPoint = CGPointMake(1, 1);
   gradient.colors = [NSArray arrayWithObjects:(id)[[UIColor colorWithRed:34.0/255.0 green:211/255.0 blue:198/255.0 alpha:1.0] CGColor],(id)[[UIColor colorWithRed:145/255.0 green:72.0/255.0 blue:203/255.0 alpha:1.0] CGColor], nil];
   [view.layer addSublayer:gradient];

UPDATED :- Swift3 +

Code :-

 var gradientView = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 35))
 let gradientLayer:CAGradientLayer = CAGradientLayer()
 gradientLayer.frame.size = self.gradientView.frame.size
 gradientLayer.colors = 
 [UIColor.white.cgColor,UIColor.red.withAlphaComponent(1).cgColor] 
//Use diffrent colors
 gradientView.layer.addSublayer(gradientLayer)

You can add starting and end point of gradient color.

  gradientLayer.startPoint = CGPoint(x: 0.0, y: 1.0)
  gradientLayer.endPoint = CGPoint(x: 1.0, y: 1.0)

For more details description refer CAGradientLayer Doc

Hope this is help for some one .

You can use map lambda

a = [2,3,4]
b = [5,6,7]
c = map(lambda x,y:(x,y),a,b)

This will also work if there lengths of original lists do not match

If you want the file to be opened with the default application, I mean without specifying Acrobat or Reader, you can't open the file in the specified page.

On the other hand, if you are Ok with specifying Acrobat or Reader, keep reading:

You can do it without telling the full Acrobat path, like this:

Process myProcess = new Process();    
myProcess.StartInfo.FileName = "acroRd32.exe"; //not the full application path
myProcess.StartInfo.Arguments = "/A \"page=2=OpenActions\" C:\\example.pdf";
myProcess.Start();

If you don't want the pdf to open with Reader but with Acrobat, chage the second line like this:

myProcess.StartInfo.FileName = "Acrobat.exe";

You can query the registry to identify the default application to open pdf files and then define FileName on your process's StartInfo accordingly.

Follow this question for details on doing that: Finding the default application for opening a particular file type on Windows

Jasypt provides the org.jasypt.properties.EncryptableProperties class for loading, managing and transparently decrypting encrypted values in .properties files, allowing the mix of both encrypted and not-encrypted values in the same file.

http://www.jasypt.org/encrypting-configuration.html

By using an org.jasypt.properties.EncryptableProperties object, an application would be able to correctly read and use a .properties file like this:

datasource.driver=com.mysql.jdbc.Driver 
datasource.url=jdbc:mysql://localhost/reportsdb 
datasource.username=reportsUser 
datasource.password=ENC(G6N718UuyPE5bHyWKyuLQSm02auQPUtm) 

Note that the database password is encrypted (in fact, any other property could also be encrypted, be it related with database configuration or not).

How do we read this value? like this:

/*
* First, create (or ask some other component for) the adequate encryptor for   
* decrypting the values in our .properties file.   
*/  
StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();     
encryptor.setPassword("jasypt"); // could be got from web, env variable...    
/*   
* Create our EncryptableProperties object and load it the usual way.   
*/  
Properties props = new EncryptableProperties(encryptor);  
props.load(new FileInputStream("/path/to/my/configuration.properties"));

/*   
* To get a non-encrypted value, we just get it with getProperty...   
*/  
String datasourceUsername = props.getProperty("datasource.username");

/*   
* ...and to get an encrypted value, we do exactly the same. Decryption will   
* be transparently performed behind the scenes.   
*/ 
String datasourcePassword = props.getProperty("datasource.password");

 // From now on, datasourcePassword equals "reports_passwd"...

I am not sure if you got this resolved. To follow up on "CommonsWare's" comment.

That is not a valid string representation of a Uri. A Uri has a scheme, and "/external/images/media/470939" does not have a scheme.

Change

Uri uri=Uri.parse("/external/images/media/470939");

to

Uri uri=Uri.parse("content://external/images/media/470939");

in my case

Uri uri = Uri.parse("content://media/external/images/media/6562");

MySQL unique and primary keys serve to identify rows. There can be only one Primary key in a table but one or more unique keys. Key is just index.

for more details you can check http://www.geeksww.com/tutorials/database_management_systems/mysql/tips_and_tricks/mysql_primary_key_vs_unique_key_constraints.php

to convert mysql to mssql try this and see http://gathadams.com/2008/02/07/convert-mysql-to-ms-sql-server/

Answer above is missing an example which might not be obvious (it wasn't to me).

Url could be broken down into parts

https://github.com/liufa/Tuplinator/commit/f36e3c5b3aba23a6c9cf7c01e7485028a23c3811
                  \_____/\________/       \_______________________________________/
                   |        |                              |
            Account name    |                      Hash of revision
                        Project name              

Hash can be found here (you can click it and will get the url from browser).

Hope this saves you some time.

Creating DLL File

1. Open Visual Studio then select File -> New -> Project

2. Select Visual C# -> Class library

3. Compile Project Or Build the solution, to create Dll File

4. Go to the class library folder (Debug Folder)

I fixed a similar issue building a RadioButtonFor with pairs of text/value from a SelectList. I used a ViewBag to send the SelectList to the View, but you can use data from model too. My web application is a Blog and I have to build a RadioButton with some types of articles when he is writing a new post.

The code below was simplyfied.

List<SelectListItem> items = new List<SelectListItem>();

Dictionary<string, string> dictionary = new Dictionary<string, string>();

dictionary.Add("Texto", "1");
dictionary.Add("Foto", "2");
dictionary.Add("Vídeo", "3");

foreach (KeyValuePair<string, string> pair in objBLL.GetTiposPost())
{
    items.Add(new SelectListItem() { Text = pair.Key, Value = pair.Value, Selected = false });
}

ViewBag.TiposPost = new SelectList(items, "Value", "Text");

In the View, I used a foreach to build a radiobutton.

<div class="form-group">
    <div class="col-sm-10">
        @foreach (var item in (SelectList)ViewBag.TiposPost)
        {
            @Html.RadioButtonFor(model => model.IDTipoPost, item.Value, false)
            <label class="control-label">@item.Text</label>
        }

    </div>
</div>

Notice that I used RadioButtonFor in order to catch the option value selected by user, in the Controler, after submit the form. I also had to put the item.Text outside the RadioButtonFor in order to show the text options.

Hope it's useful!

it works on anaconda3 windows 10 I have already downloaded it at 5 December 2019.

Firstly, using this command:

pip install opencv-contrib-python

after that windows will ask for permission and try again:

pip install opencv-contrib-python --user

look at this it works!!

Use this construction, to keep all input params but page

{!! $myItems->appends(Request::capture()->except('page'))->render() !!}

Why?

1) you strip down everything that added to request like that

  $request->request->add(['variable' => 123]);

2) you don't need $request as input parameter for the function

3) you are excluding "page"

PS) and it works for Laravel 5.1

If you're using Spring Boot (2.0.0+) you can use:

import org.springframework.util.StringUtils;

...
.filter(StringUtils::hasLength)
...

Which does: return (str != null && !str.isEmpty());

So it will have the required negation effect for isEmpty

No You shouldn't test the Private Methods why? and moreover the popular mocking framework such as Mockito doesn't provide support for testing private methods.

It's far from pretty, but you could create a script or an alias that does something like this:

for c in $(git for-each-ref refs/tags/ --format='%(refname)'); do echo $c; git show --quiet "$c"; echo; done

If you're targeting at or above iOS 8 or OS X 10.10, this just got a lot easier. The new NSDateComponentsFormatter class allows you to convert a given NSTimeInterval from its value in seconds to a localized string to show the user. For example:

Objective-C

NSTimeInterval interval = 326.4;

NSDateComponentsFormatter *componentFormatter = [[NSDateComponentsFormatter alloc] init];

componentFormatter.unitsStyle = NSDateComponentsFormatterUnitsStylePositional;
componentFormatter.zeroFormattingBehavior = NSDateComponentsFormatterZeroFormattingBehaviorDropAll;

NSString *formattedString = [componentFormatter stringFromTimeInterval:interval];
NSLog(@"%@",formattedString); // 5:26

Swift

let interval = 326.4

let componentFormatter = NSDateComponentsFormatter()

componentFormatter.unitsStyle = .Positional
componentFormatter.zeroFormattingBehavior = .DropAll

if let formattedString = componentFormatter.stringFromTimeInterval(interval) {
    print(formattedString) // 5:26
}

NSDateCompnentsFormatter also allows for this output to be in longer forms. More info can be found in NSHipster's NSFormatter article. And depending on what classes you're already working with (if not NSTimeInterval), it may be more convenient to pass the formatter an instance of NSDateComponents, or two NSDate objects, which can be done as well via the following methods.

Objective-C

NSString *formattedString = [componentFormatter stringFromDate:<#(NSDate *)#> toDate:<#(NSDate *)#>];
NSString *formattedString = [componentFormatter stringFromDateComponents:<#(NSDateComponents *)#>];

Swift

if let formattedString = componentFormatter.stringFromDate(<#T##startDate: NSDate##NSDate#>, toDate: <#T##NSDate#>) {
    // ...
}

if let formattedString = componentFormatter.stringFromDateComponents(<#T##components: NSDateComponents##NSDateComponents#>) {
    // ...
}

It's safe to just delete the source directory and compiled package file. Find the source directory under $GOPATH/src and the package file under $GOPATH/pkg/<architecture>, for example: $GOPATH/pkg/windows_amd64.

It's not Twitter bootstrap specific, it is a normal HTML5 component and you can specify the range with the min and max attributes (in your case only the first attribute). For example:

<div>                       _x000D_
    <input type="number" id="replyNumber" min="0" data-bind="value:replyNumber" />_x000D_
</div>

I'm not sure if only integers are allowed by default in the control or not, but else you can specify the step attribute:

<div>                       _x000D_
    <input type="number" id="replyNumber" min="0" step="1" data-bind="value:replyNumber" />_x000D_
</div>

Now only numbers higher (and equal to) zero can be used and there is a step of 1, which means the values are 0, 1, 2, 3, 4, ... .

BE AWARE: Not all browsers support the HTML5 features, so it's recommended to have some kind of JavaScript fallback (and in your back-end too) if you really want to use the constraints.

For a list of browsers that support it, you can look at caniuse.com.

\df+ in psql gives you the sourcecode.

Use a grep analog to find the strings oldnamespace and Jenine inside the files in your whole project folder. Then you'd know what step to do next.

It's the remainder operator and is used to get the remainder after integer division. Lots of languages have it. For example:

10 % 3 // = 1 ; because 3 * 3 gets you 9, and 10 - 9 is 1.

Apparently it is not the same as the modulo operator entirely.

As everyone said, references can't be null. That is because, a reference refers to an object. In your code:

// this compiles, but doesn't work, and does this even mean anything?
if (&str == NULL)

you are taking the address of the object str. By definition, str exists, so it has an address. So, it cannot be NULL. So, syntactically, the above is correct, but logically, the if condition is always going to be false.

About your questions: it depends upon what you want to do. Do you want the function to be able to modify the argument? If yes, pass a reference. If not, don't (or pass reference to const). See this C++ FAQ for some good details.

In general, in C++, passing by reference is preferred by most people over passing a pointer. One of the reasons is exactly what you discovered: a reference can't be NULL, thus avoiding you the headache of checking for it in the function.

You could try this:

{% if not profile.user.first_name.value %}
  <p> -- </p>
{% else %}
  {{ profile.user.first_name }} {{ profile.user.last_name }}
{% endif %}

This way, you're essentially checking to see if the form field first_name has any value associated with it. See {{ field.value }} in Looping over the form's fields in Django Documentation.

I'm using Django 3.0.

Generate pseudo random numbers between 1 and an [UPPER_LIMIT]

You can use the following to generate a number between 1 and an upper limit.

Math.abs(new Random().nextInt() % [UPPER_LIMIT]) + 1

Here is a specific example:

Example - Generate pseudo random numbers in the range 1 to 600:

Math.abs(new Random().nextInt() % 600) + 1

This will generate a random number within a range for you. In this case 1-600. You can change the value 600 to anything you need in the range of integers.

Generate pseudo random numbers between a [LOWER_LIMIT] and an [UPPER_LIMIT]

If you want to use a lower bound that is not equal to 1 then you can use the following formula.

Math.abs(new Random().nextInt() % ([UPPER_LIMIT] - [LOWER_LIMIT])) + [LOWER_LIMIT]

Here is a specific example:

Example - Generate pseudo random numbers in the range of 40 to 99:

Math.abs( new Random().nextInt() % (99 - 40) ) + 40

This will generate a random number within a range of 40 and 99.

You're talking about histograms, but this doesn't quite make sense. Histograms and bar charts are different things. An histogram would be a bar chart representing the sum of values per year, for example. Here, you just seem to be after bars.

Here is a complete example from your data that shows a bar of for each required value at each date:

import pylab as pl
import datetime

data = """0 14-11-2003
1 15-03-1999
12 04-12-2012
33 09-05-2007
44 16-08-1998
55 25-07-2001
76 31-12-2011
87 25-06-1993
118 16-02-1995
119 10-02-1981
145 03-05-2014"""

values = []
dates = []

for line in data.split("\n"):
    x, y = line.split()
    values.append(int(x))
    dates.append(datetime.datetime.strptime(y, "%d-%m-%Y").date())

fig = pl.figure()
ax = pl.subplot(111)
ax.bar(dates, values, width=100)
ax.xaxis_date()

You need to parse the date with strptime and set the x-axis to use dates (as described in this answer).

If you're not interested in having the x-axis show a linear time scale, but just want bars with labels, you can do this instead:

fig = pl.figure()
ax = pl.subplot(111)
ax.bar(range(len(dates)), values)

EDIT: Following comments, for all the ticks, and for them to be centred, pass the range to set_ticks (and move them by half the bar width):

fig = pl.figure()
ax = pl.subplot(111)
width=0.8
ax.bar(range(len(dates)), values, width=width)
ax.set_xticks(np.arange(len(dates)) + width/2)
ax.set_xticklabels(dates, rotation=90)

Here you can access "set2" property following:

    var obj = {
        "set1": [1, 2, 3],
        "set2": [4, 5, 6, 7, 8],
        "set3": [9, 10, 11, 12]
    };

    var output = Object.keys(obj)[1];

Object.keys return all the keys of provided object as Array..

Same thing is happened with 8.0+ versions as well. By default in 8.0+ version it is "enabled" by default. Here is the link official document reference

In case of 5.6+, 5.7+ versions, the property "ONLY_FULL_GROUP_BY" is disabled by default.

To disabled it, follow the same steps suggested by @Miloud BAKTETE

        try{
            Class.forName("com.mysql.cj.jdbc.Driver").newInstance();
            Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/bala","bala","bala");
            if(con == null) System.out.print("not connected");
            Statement st = con.createStatement();
            String myStatement = "select count(*) as total from locations";
            ResultSet rs = st.executeQuery(myStatement);
            int num = 0;
            while(rs.next()){
                num = (rs.getInt(1));
            }

        }
        catch(Exception e){
            System.out.println(e);  
        }

        %>

If #restart is an inline element (eg <span>, <em> etc) then you can turn it into a block element using:

#restart { display: block; }

This will have the effect of ensuring a line break both before and after the element.

There is not a way to have CSS insert something that acts like a line break only before an element and not after. You could perhaps cause a line-break before as a side-effect of other changes, for example float: left, or clear: left after a floated element, or even something crazy like #restart:before { content: 'a load of non-breaking spaces'; } but this probably isn't a good idea in the general case.

@EmailAddress varchar(200),
@NickName varchar(100),
@Password varchar(150),
@Sex varchar(50),
@Age int,
@EmailUpdates int,
@UserId int OUTPUT
DECLARE @AA INT
SET @AA=(SELECT COUNT(UserId) FROM RegUsers WHERE EmailAddress = @EmailAddress)

IF @AA> 0
    BEGIN
        SET @UserId = 0
    END
ELSE
    BEGIN
        INSERT INTO RegUsers (EmailAddress,NickName,PassWord,Sex,Age,EmailUpdates) VALUES (@EmailAddress,@NickName,@Password,@Sex,@Age,@EmailUpdates)
        SELECT SCOPE_IDENTITY()
    END

http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html#import

doesn't look like it.

If any of these files always require the others, then have them import the other files and only import the top-level ones. If they're all standalone, then I think you're going to have to keep doing it like you are now.

Here's a C++ example, based on some of the references. This is quick and dirty, you are better off not re-inventing and using the boost library.

#include "math.h" // for RAND, and rand
double sampleNormal() {
    double u = ((double) rand() / (RAND_MAX)) * 2 - 1;
    double v = ((double) rand() / (RAND_MAX)) * 2 - 1;
    double r = u * u + v * v;
    if (r == 0 || r > 1) return sampleNormal();
    double c = sqrt(-2 * log(r) / r);
    return u * c;
}

You can use a Q-Q plot to examine the results and see how well it approximates a real normal distribution (rank your samples 1..x, turn the ranks into proportions of total count of x ie. how many samples, get the z-values and plot them. An upwards straight line is the desired result).

This is a simple way to add to an array in java. I used a second array to store my original array, and then added one more element to it. After that I passed that array back to the original one.

    int [] test = {12,22,33};
    int [] test2= new int[test.length+1];
    int m=5;int mz=0;
    for ( int test3: test)        
    {          
    test2[mz]=test3; mz++;        
    } 
    test2[mz++]=m;
    test=test2;

    for ( int test3: test)

    {
      System.out.println(test3);
    }

Since it's a user-facing page always use 404. It's the only code people know usually.

I suspect it's just following the Linux / Unix standard for returning 0 on success.

Does it really say "1" is false and "0" is true?

Apache Commons has a method CollectionUtils.containsAny().

Another use is to split the implementation of different interfaces, e.g:

partial class MyClass : IF3
{
    // main implementation of MyClass
}


partial class MyClass : IF1
{
    // implementation of IF1
}

partial class MyClass : IF2
{
    // implementation of IF2
}

Is this really possible.

Yes.

function a(x) {    // <-- function_x000D_
  function b(y) { // <-- inner function_x000D_
    return x + y; // <-- use variables from outer scope_x000D_
  }_x000D_
  return b;       // <-- you can even return a function._x000D_
}_x000D_
console.log(a(3)(4));

"Validation injection without submit looping":

I just want to check reCaptcha and some other stuff before HTML5 validation, so I did something like that (the validation function returns true or false):

$(document).ready(function(){
   var application_form = $('form#application-form');

   application_form.on('submit',function(e){

        if(application_form_extra_validation()===true){
           return true;
        }

        e.preventDefault();

   });
});

Try the following:

    ....
    character(len=30) :: filename  ! length depends on expected names
    integer           :: inuit
    ....
    do i=1,n
        write(filename,'("output",i0,".txt")') i
        open(newunit=iunit,file=filename,...)
        ....
        close(iunit)
    enddo
    ....

Where "..." means other appropriate code for your purpose.
