Leap years are arbitrary, and the system used to describe them is a man made construct. There is no why.

What I mean is there could have been a leap year every 28 years and we would have an extra week in those leap years ... but the powers that be decided to make it a day every 4 years to catch up.

It also has to do with the earth taking a pesky 365.25 days to go round the sun etc. Of course it isn't really 365.25 is it slightly less (365.242222...), so to correct for this discrepancy they decided drop the leap years that are divisible by 100.

If you are using java8 :

java.time.Year.of(year).isLeap()

Java implementation of above method:

public static boolean isLeap(long year) {
        return ((year & 3) == 0) && ((year % 100) != 0 || (year % 400) == 0);
    }

You can try:

int sum = startingNumber; 
for (int i=0; i < positiveInteger; i++) {     
    sum += i;
}
cout << sum;

But much easier is to note that the sum 1+2+...+n = n*(n+1) / 2, so you do not need a loop at all, just use the formula n*(n+1)/2.

The way I always do it (assuming the data is never to be deleted, only inserted) is to

• Firstly do an insert, if this fails with a unique constraint violation then you know the row is there,
• Then do an update

Unfortunately many frameworks such as Hibernate treat all database errors (e.g. unique constraint violation) as unrecoverable conditions, so it isn't always easy. (In Hibernate the solution is to open a new session/transaction just to execute this one insert command.)

You can't just do a select count(*) .. where .. as even if that returns zero, and therefore you choose to do an insert, between the time you do the select and the insert someone else might have inserted the row and therefore your insert will fail.

you can make that using transform and transform origins.

Combining various transfroms gives similar result. I hope you find it helpful. :) See these examples for simpler transforms. this has left point :

what transform: 0% 50%; does is it sets the origin to vertical middle and horizontal left of the element. so the perspective is not visible at the left part of the image, so it looks flat. Perspective effect is there at the right part, so it looks slanted.

I arrived here from a google search, since my other code is 'tidy' so leaving the 'tidy' way for anyone who else who may find it useful

library(dplyr)
iris %>% 
  mutate(Species = ifelse(as.character(Species) == "virginica", "newValue", as.character(Species)))

Try using the simple http.get(options, callback) function in node.js:

var http = require('http');
var options = {
  host: 'www.google.com',
  path: '/index.html'
};

var req = http.get(options, function(res) {
  console.log('STATUS: ' + res.statusCode);
  console.log('HEADERS: ' + JSON.stringify(res.headers));

  // Buffer the body entirely for processing as a whole.
  var bodyChunks = [];
  res.on('data', function(chunk) {
    // You can process streamed parts here...
    bodyChunks.push(chunk);
  }).on('end', function() {
    var body = Buffer.concat(bodyChunks);
    console.log('BODY: ' + body);
    // ...and/or process the entire body here.
  })
});

req.on('error', function(e) {
  console.log('ERROR: ' + e.message);
});

There is also a general http.request(options, callback) function which allows you to specify the request method and other request details.

First you use a full stop, then you hold down alt and press the letter H and put in another full stop. .?.

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

Let's say the name was used in a variable, $Name.

You then run this query:

INSERT INTO Students VALUES ( '$Name' )

The code is mistakenly placing anything the user supplied as the variable.

You wanted the SQL to be:

INSERT INTO Students VALUES ( 'Robert Tables` )

But a clever user can supply whatever they want:

INSERT INTO Students VALUES ( 'Robert'); DROP TABLE Students; --' )

What you get is:

INSERT INTO Students VALUES ( 'Robert' );  DROP TABLE STUDENTS; --' )

The -- only comments the remainder of the line.

You need to actually use the shortened array after you remove items from it. You are ignoring the shortened array.

You convert the cookie into an array. You reduce the length of the array and then you never use that shortened array. Instead, you just use the old cookie (the unshortened one).

You should convert the shortened array back to a string with .join(",") and then use it for the new cookie instead of using old_cookie which is not shortened.

You may also not be using .splice() correctly, but I don't know exactly what your objective is for shortening the array. You can read about the exact function of .splice() here.

I realize this is pretty late, but I had a similar problem and I figured I'd post what worked for me. I used the iconv utility (e.g., "iconv file.pcl -f UTF-8 -t ISO-8859-1 -c"). The "-c" option skips characters that can't be translated.

Some good answers here but none cover the case of your start time being in a different day than your end time. If you need to straddle the day boundary, then something like this may help:

TimeSpan start = TimeSpan.Parse("22:00"); // 10 PM
TimeSpan end = TimeSpan.Parse("02:00");   // 2 AM
TimeSpan now = DateTime.Now.TimeOfDay;

if (start <= end)
{
    // start and stop times are in the same day
    if (now >= start && now <= end)
    {
        // current time is between start and stop
    }
}
else
{
    // start and stop times are in different days
    if (now >= start || now <= end)
    {
       // current time is between start and stop
    }
}

Note that in this example the time boundaries are inclusive and that this still assumes less than a 24-hour difference between start and stop.

With Java 9 you can do the following:

Set.of("a", "b");

and you'll get an immutable Set containing the elements. For details see the Oracle documentation of interface Set.

If no proxy

To see from the client side and server side are the same:

Client -> Server

Proxy

From the client side:

Client -> proxy -> Server

From the server side:

Client -> Server

Reverse proxy

From the client side:

Client -> Server

From the server side:

Client -> proxy -> Server

So I think if it set up by a client user,it is called a proxy; if it set up by a server manager it is a reverse proxy.

Because the purposes and reasons for setting it up are different, they deal with data in different ways and use different software.

   User side          |      Server side
client  <->  proxy  <-->  reverse_proxy <-> real server

Here some basic explanation of hibernate cache...

First level cache is associated with “session” object. The scope of cache objects is of session. Once session is closed, cached objects are gone forever. First level cache is enabled by default and you can not disable it. When we query an entity first time, it is retrieved from database and stored in first level cache associated with hibernate session. If we query same object again with same session object, it will be loaded from cache and no sql query will be executed. The loaded entity can be removed from session using evict() method. The next loading of this entity will again make a database call if it has been removed using evict() method. The whole session cache can be removed using clear() method. It will remove all the entities stored in cache.

Second level cache is apart from first level cache which is available to be used globally in session factory scope. second level cache is created in session factory scope and is available to be used in all sessions which are created using that particular session factory. It also means that once session factory is closed, all cache associated with it die and cache manager also closed down. Whenever hibernate session try to load an entity, the very first place it look for cached copy of entity in first level cache (associated with particular hibernate session). If cached copy of entity is present in first level cache, it is returned as result of load method. If there is no cached entity in first level cache, then second level cache is looked up for cached entity. If second level cache has cached entity, it is returned as result of load method. But, before returning the entity, it is stored in first level cache also so that next invocation to load method for entity will return the entity from first level cache itself, and there will not be need to go to second level cache again. If entity is not found in first level cache and second level cache also, then database query is executed and entity is stored in both cache levels, before returning as response of load() method.

You're getting the toString() value returned by the Scanner object itself which is not what you want and not how you use a Scanner object. What you want instead is the data obtained by the Scanner object. For example,

Scanner input = new Scanner(System.in);
String data = input.nextLine();
System.out.println(data);

Please read the tutorial on how to use it as it will explain all.

Edit
Please look here: Scanner tutorial

Also have a look at the Scanner API which will explain some of the finer points of Scanner's methods and properties.

To get the *N*th highest value, better to use this solution:

SELECT * FROM `employees`  WHERE salary =
         (SELECT DISTINCT(salary) FROM `employees` 
         ORDER BY salary DESC LIMIT {N-1},1);

or you can try with:

SELECT * FROM `employees` e1 WHERE 
        (N-1) = (SELECT COUNT(DISTINCT(salary)) 
        FROM `employees` e2 
        WHERE e1.salary < e2.salary ); 

N=2 for second highest N=3 for third highest and so on.

you need to add jar file in your build path..

commons-dbcp-1.1-RC2.jar

or any version of that..!!!!

ADDED : also make sure you have commons-pool-1.1.jar too in your build path.

ADDED: sorry saw complete list of jar late... may be version clashes might be there.. better check out..!!! just an assumption.

You have to start a service in your Application class to run it always. If you do that, your service will be always running. Even though user terminates your app from task manager or force stop your app, it will start running again.

Create a service:

public class YourService extends Service {

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // do your jobs here
        return super.onStartCommand(intent, flags, startId);
    }
}

Create an Application class and start your service:

public class App extends Application {

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

        startService(new Intent(this, YourService.class));
    }
}

Add "name" attribute into the "application" tag of your AndroidManifest.xml

android:name=".App"

Also, don't forget to add your service in the "application" tag of your AndroidManifest.xml

<service android:name=".YourService"/>

And also this permission request in the "manifest" tag (if API level 28 or higher):

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

UPDATE

After Android Oreo, Google introduced some background limitations. Therefore, this solution above won't work probably. When a user kills your app from task manager, Android System will kill your service as well. If you want to run a service which is always alive in the background. You have to run a foreground service with showing an ongoing notification. So, edit your service like below.

public class YourService extends Service {

    private static final int NOTIF_ID = 1;
    private static final String NOTIF_CHANNEL_ID = "Channel_Id";

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId){

        // do your jobs here

        startForeground();
        
        return super.onStartCommand(intent, flags, startId);
    }

    private void startForeground() {
        Intent notificationIntent = new Intent(this, MainActivity.class);

        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
                notificationIntent, 0);

        startForeground(NOTIF_ID, new NotificationCompat.Builder(this, 
                NOTIF_CHANNEL_ID) // don't forget create a notification channel first
                .setOngoing(true)
                .setSmallIcon(R.drawable.ic_notification)
                .setContentTitle(getString(R.string.app_name))
                .setContentText("Service is running background")
                .setContentIntent(pendingIntent)
                .build());         
    }
}

EDIT: RESTRICTED OEMS

Unfortunately, some OEMs (Xiaomi, OnePlus, Samsung, Huawei etc.) restrict background operations due to provide longer battery life. There is no proper solution for these OEMs. Users need to allow some special permissions that are specific for OEMs or they need to add your app into whitelisted app list by device settings. You can find more detail information from https://dontkillmyapp.com/.

If background operations are an obligation for you, you need to explain it to your users why your feature is not working and how they can enable your feature by allowing those permissions. I suggest you to use AutoStarter library (https://github.com/judemanutd/AutoStarter) in order to redirect your users regarding permissions page easily from your app.

By the way, if you need to run some periodic work instead of having continuous background job. You better take a look WorkManager (https://developer.android.com/topic/libraries/architecture/workmanager)

Also compare the results with the following query's result

EXEC sp_helpdb @dbname= 'MSDB'

It produces result similar to the following

There is a good article - Different ways to determine free space for SQL Server databases and database files

I'll tell you what worked for me:

int id = int.Parse(insertItem.OwnerTableView.DataKeyValues[insertItem.ItemIndex]["id_usuario"].ToString());

var query = user.First(x => x.id_usuario == id);
tbUsername.Text = query.username;
tbEmail.Text = query.email;
tbPassword.Text = query.password;

My id is the row I want to query, in this case I got it from a radGrid, then I used it to query, but this query returns a row, then you can assign the values you got from the query to textbox, or anything, I had to assign those to textbox.

The problem is that your regex is a string, but html is bytes:

>>> type(html)
<class 'bytes'>

Since python doesn't know how those bytes are encoded, it throws an exception when you try to use a string regex on them.

You can either decode the bytes to a string:

html = html.decode('ISO-8859-1')  # encoding may vary!
title = re.findall(pattern, html)  # no more error

Or use a bytes regex:

regex = rb'<title>(,+?)</title>'
#        ^

In this particular context, you can get the encoding from the response headers:

with urllib.request.urlopen(url) as response:
    encoding = response.info().get_param('charset', 'utf8')
    html = response.read().decode(encoding)

See the urlopen documentation for more details.

You can kill all node processes using pkill node

or you can do a ps T to see all processes on this terminal
then you can kill a specific process ID doing a kill [processID] example: kill 24491

Additionally, you can do a ps -help to see all the available options

A better solution would be you use in style css, the command to break lines. Works in older versions of browsers.

p {
word-wrap: break-word;
}

There is no option to downgrade XAMPP. XAMPP is hardcoded with specific PHP version to make sure all the modules are compatible and working properly. However if your project needs PHP 5.6, you can just install a older version of XAMPP with PHP 5.6 packaged into it.

If I uninstall Dropbox only "*/*" works to open file browser. This is Android 4.4.2. I can download contents from Dropbox and for Google Drive, by getContentResolver().openInputStream(data.getData()).

Vertical-align is one of the most misused css styles. It doesn't work how you might expect on elements that are not td's or css "display: table-cell".

This is a very good post on the matter. http://phrogz.net/CSS/vertical-align/index.html

The most common methods to acheive what you're looking for are:

• padding top/bottom
• position absolute
• line-height

I am assuming that active events in a time period means at least one day of the event falls inside the time period. This is a simple "find overlapping dates" problem and there is a generic solution:

-- [@d1, @d2] is the date range to check against
SELECT * FROM events WHERE @d2 >= start AND end >= @d1

Some tests:

-- list of events
SELECT * FROM events;
+------+------------+------------+
| id   | start      | end        |
+------+------------+------------+

|    5 | 2013-07-30 | 2013-07-31 |
+------+------------+------------+

-- events between [2013-06-01, 2013-06-15]
SELECT * FROM events WHERE '2013-06-15' >= start AND end >= '2013-06-01';

I think df['word'].value_counts() should serve. By skipping the groupby machinery, you'll save some time. I'm not sure why count should be much slower than max. Both take some time to avoid missing values. (Compare with size.)

In any case, value_counts has been specifically optimized to handle object type, like your words, so I doubt you'll do much better than that.

The use of IIF? And it depends on version of SQL Server.

SELECT
IIF(Column1 = Column2, 1, 0) AS MyDesiredResult
FROM Table;

You have to create an object. Assign the values to the object. Then push it into the array:

var nietos = [];
var obj = {};
obj["01"] = nieto.label;
obj["02"] = nieto.value;
nietos.push(obj);

The other answers here cover this well, but it is worth knowing that there is built in functionality for splash screens in Visual Studio: If you open the project properties for the windows form app and look at the Application tab, there is a "Splash screen:" option at the bottom. You simply pick which form in your app you want to display as the splash screen and it will take care of showing it when the app starts and hiding it once your main form is displayed.

You still need to set up your form as described above (with the correct borders, positioning, sizing etc.)

$(document).ready(
    function()
    {
        $("input:checkbox").change(
            function()
            {
                if( $(this).is(":checked") )
                {
                    $("#formName").submit();
                }
            }
        )
    }
);

Though it would probably be better to add classes to each of the checkboxes and do

$(".checkbox_class").change();

so that you can choose which checkboxes submit the form instead of all of them doing it.

Spring container generates bean objects depending on the bean scope (singleton, prototype etc..). So this looks like implementing Abstract Factory pattern. In the Spring's internal implementation, I am sure each scope should be tied to specific factory kind class.

There isn't a good way to do this in SQL. Some approaches I have seen:

1) Use CASE combined with boolean operators:

WHERE
    OrderNumber = CASE 
        WHEN (IsNumeric(@OrderNumber) = 1)
        THEN CONVERT(INT, @OrderNumber)
        ELSE -9999 -- Some numeric value that just cannot exist in the column
    END
    OR 
    FirstName LIKE CASE
        WHEN (IsNumeric(@OrderNumber) = 0)
        THEN '%' + @OrderNumber
        ELSE ''
    END

2) Use IF's outside the SELECT

IF (IsNumeric(@OrderNumber)) = 1
BEGIN
    SELECT * FROM Table
    WHERE @OrderNumber = OrderNumber
END ELSE BEGIN
    SELECT * FROM Table
    WHERE OrderNumber LIKE '%' + @OrderNumber
END

3) Using a long string, compose your SQL statement conditionally, and then use EXEC

The 3rd approach is hideous, but it's almost the only think that works if you have a number of variable conditions like that.

This can be achieved in CSS using the :hover pseudo-class. (:hover doesn't work on <div>s in IE6)

HTML:

<div id="menu">
   <a class="menuItem" href=#>Bla</a>
   <a class="menuItem" href=#>Bla</a>
   <a class="menuItem" href=#>Bla</a>
</div>

CSS:

.menuItem{
  height:30px;
  width:100px;
  background-color:#000;
}
.menuItem:hover {
  background-color:#F00;
}

you have to put the headers keys/values in options method response. for example if you have resource at http://mydomain.com/myresource then, in your server code you write

//response handler
void handleRequest(Request request, Response response) {
    if(request.method == "OPTIONS") {
       response.setHeader("Access-Control-Allow-Origin","http://clientDomain.com")
       response.setHeader("Access-Control-Allow-Methods", "GET,POST,PUT,DELETE,OPTIONS");
       response.setHeader("Access-Control-Allow-Headers", "Content-Type");
    }



}

SQL Developer seems to only output the DBMS_OUTPUT text when you have explicitly turned on the DBMS_OUTPUT window pane.

Go to (Menu) VIEW -> Dbms_output to invoke the pane.

Click on the Green Plus sign to enable output for your connection and then run the code.

EDIT: Don't forget to set the buffer size according to the amount of output you are expecting.

I think this is a file problem, you simple saved your file in 1-byte encoding like latin-1. Google up your editor and how to set files to utf-8.

I wonder why there are editors that don't default to utf-8.

Now you can use nameof:

public static void Output<T>(IEnumerable<T> dataSource) where T : class
{
    string dataSourceName = typeof(T).Name;
    switch (dataSourceName)
    {
        case nameof(CustomerDetails):
            var t = 123;
            break;
        default:
            Console.WriteLine("Test");
    }
}

nameof(CustomerDetails) is basically identical to the string literal "CustomerDetails", but with a compile-time check that it refers to some symbol (to prevent a typo).

nameof appeared in C# 6.0, so after this question was asked.

Just try to run the following command manually:

C:\wamp\bin\mysql\mysql5.6.17\bin\mysqld.exe --console

It worked for me :)

Using a regex

#include <regex>
#include <string>

string trim(string s) {
    regex e("^\\s+|\\s+$");   // remove leading and trailing spaces
    return regex_replace(s, e, "");
}

If you want to append to the lists of each key inside a dictionary, you can append new values to them using + operator (tested in Python 3.7):

mydict = {'a':[], 'b':[]}
print(mydict)
mydict['a'] += [1,3]
mydict['b'] += [4,6]
print(mydict)
mydict['a'] += [2,8]
print(mydict)

and the output:

{'a': [], 'b': []}
{'a': [1, 3], 'b': [4, 6]}
{'a': [1, 3, 2, 8], 'b': [4, 6]}

mydict['a'].extend([1,3]) will do the job same as + without creating a new list (efficient way).

Refer the below link.

There are two important changes that you should make

driver name as "com.microsoft.sqlserver.jdbc.SQLServerDriver"

& in URL "jdbc:sqlserver://localhost:1433"+";databaseName=AdventureWorks2008R2"

http://www.programcreek.com/2010/05/java-code-for-connecting-ms-sql-server-by-using-sql-server-authentication/

With this we can pass a key function to use for the sorting

Array.prototype.sortBy = function(key_func, reverse=false){
    return this.sort( (a, b) => {
        var keyA = key_func(a),
            keyB = key_func(b);
        if(keyA < keyB) return reverse? 1: -1;
        if(keyA > keyB) return reverse? -1: 1;
        return 0;
    }); 
}

Then for example if we have

var arr = [ {date: "01/12/00", balls: {red: "a8",  blue: 10}},
            {date: "12/13/05", balls: {red: "d6" , blue: 11}},
            {date: "03/02/04", balls: {red: "c4" , blue: 15}} ]

We can do

arr.sortBy(el => el.balls.red)
/* would result in
[ {date: "01/12/00", balls: {red: "a8", blue: 10}},
  {date: "03/02/04", balls: {red: "c4", blue: 15}},
  {date: "12/13/05", balls: {red: "d6", blue: 11}} ]
*/

or

arr.sortBy(el => new Date(el.date), true)   // second argument to reverse it
/* would result in
[ {date: "12/13/05", balls: {red: "d6", blue:11}},
  {date: "03/02/04", balls: {red: "c4", blue:15}},
  {date: "01/12/00", balls: {red: "a8", blue:10}} ]
*/

or

arr.sortBy(el => el.balls.blue + parseInt(el.balls.red[1]))
/* would result in
[ {date: "12/13/05", balls: {red: "d6", blue:11}},    // red + blue= 17
  {date: "01/12/00", balls: {red: "a8", blue:10}},    // red + blue= 18
  {date: "03/02/04", balls: {red: "c4", blue:15}} ]   // red + blue= 19
*/

I'm an Eclipse/Android beginner as well, but hopefully my simple debugging process can help...

You set breakpoints in Eclipse by right-clicking next to the line you want to break at and selecting "Toggle Breakpoint". From there you'll want to select "Debug" rather than the standard "Run", which will allow you to step through and so on. Use the filters provided by LogCat (referenced in your tutorial) so you can target the messages you want rather than wading through all the output. That will (hopefully) go a long way in helping you make sense of your errors.

As for other good tutorials, I was searching around for a few myself, but didn't manage to find any gems yet.

java.time.Duration

I still didn’t feel any of the answers was quite up to date and to the point. So here is the modern answer using Duration from java.time, the modern Java date and time API (the answers by MayurB and mkobit mention the same class, but none of them correctly converts to days, hours, minutes and minutes as asked).

    DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yy/MM/dd HH:mm:ss");
    
    String dateStart = "11/03/14 09:29:58";
    String dateStop = "11/03/14 09:33:43";

    ZoneId zone = ZoneId.systemDefault();
    ZonedDateTime startDateTime = LocalDateTime.parse(dateStart, formatter).atZone(zone);
    ZonedDateTime endDateTime = LocalDateTime.parse(dateStop, formatter).atZone(zone);
    
    Duration diff = Duration.between(startDateTime, endDateTime);
    if (diff.isZero()) {
        System.out.println("0 minutes");
    } else {
        long days = diff.toDays();
        if (days != 0) {
            System.out.print("" + days + " days ");
            diff = diff.minusDays(days);
        }
        long hours = diff.toHours();
        if (hours != 0) {
            System.out.print("" + hours + " hours ");
            diff = diff.minusHours(hours);
        }
        long minutes = diff.toMinutes();
        if (minutes != 0) {
            System.out.print("" + minutes + " minutes ");
            diff = diff.minusMinutes(minutes);
        }
        long seconds = diff.getSeconds();
        if (seconds != 0) {
            System.out.print("" + seconds + " seconds ");
        }
        System.out.println();
    }

Output from this example snippet is:

3 minutes 45 seconds

Note that Duration always counts a day as 24 hours. If you want to treat time anomalies like summer time transistions differently, solutions inlcude (1) use ChronoUnit.DAYS (2) Use Period (3) Use LocalDateTimeinstead ofZonedDateTime` (may be considered a hack).

The code above works with Java 8 and with ThreeTen Backport, that backport of java.time to Java 6 and 7. From Java 9 it may be possible to write it a bit more nicely using the methods toHoursPart, toMinutesPart and toSecondsPart added there.

I will elaborate the explanations further one of the days when I get time, maybe not until next week.

Follow the Instructions from the Ruby Installer Developer Kit Wiki:

1. Download Ruby 1.9.3 from rubyinstaller.org
2. Download DevKit file from rubyinstaller.org
   • For Ruby 1.9.3 use DevKit-tdm-32-4.5.2-20110712-1620-sfx.exe
3. Extract DevKit to path C:\Ruby193\DevKit
4. Run cd C:\Ruby193\DevKit
5. Run ruby dk.rb init
6. Run ruby dk.rb review
7. Run ruby dk.rb install

To return to the problem at hand, you should be able to install JSON (or otherwise test that your DevKit successfully installed) by running the following commands which will perform an install of the JSON gem and then use it:

gem install json --platform=ruby
ruby -rubygems -e "require 'json'; puts JSON.load('[42]').inspect"

If your ultimate aim is to get debugging messages to the console, you can use qDebug().

You can use like,

qDebug()<<string; which will print the contents to the console.

This way is better than converting it into std::string just for the sake of debugging messages.

At the risk of causing some cringing by purests and c# programmers, you can use multiple statements and else in a one-line if statement in VB. In this example, y ends up 3 and not 7.

i = 1
If i = 1 Then x = 3 : y = 3 Else x = 7 : y = 7

I bet the problem is when you are trying to replace values with a new one, one that is not currently part of the existing factor's levels:

levels(iris$Species)
# [1] "setosa"     "versicolor" "virginica" 

Your example was bad, this works:

iris$Species[iris$Species == 'virginica'] <- 'setosa'

This is what more likely creates the problem you were seeing with your own data:

iris$Species[iris$Species == 'virginica'] <- 'new.species'
# Warning message:
# In `[<-.factor`(`*tmp*`, iris$Species == "virginica", value = c(1L,  :
#   invalid factor level, NAs generated

It will work if you first increase your factor levels:

levels(iris$Species) <- c(levels(iris$Species), "new.species")
iris$Species[iris$Species == 'virginica'] <- 'new.species'

If you want to replace "species A" with "species B" you'd be better off with

levels(iris$Species)[match("oldspecies",levels(iris$Species))] <- "newspecies"

Why not just reload the page when the user rotates the screen with javascript

function doOnOrientationChange()
{
location.reload();
}

window.addEventListener('orientationchange', doOnOrientationChange);

Your problem is basically that you never specified the right path to the file.

Try instead, from your main script:

from folder.file import Klasa

Or, with from folder import file:

from folder import file
k = file.Klasa()

Or again:

import folder.file as myModule
k = myModule.Klasa()

Another very simple way to estimate the sharpness of an image is to use a Laplace (or LoG) filter and simply pick the maximum value. Using a robust measure like a 99.9% quantile is probably better if you expect noise (i.e. picking the Nth-highest contrast instead of the highest contrast.) If you expect varying image brightness, you should also include a preprocessing step to normalize image brightness/contrast (e.g. histogram equalization).

I've implemented Simon's suggestion and this one in Mathematica, and tried it on a few test images:

The first test blurs the test images using a Gaussian filter with a varying kernel size, then calculates the FFT of the blurred image and takes the average of the 90% highest frequencies:

testFft[img_] := Table[
  (
   blurred = GaussianFilter[img, r];
   fft = Fourier[ImageData[blurred]];
   {w, h} = Dimensions[fft];
   windowSize = Round[w/2.1];
   Mean[Flatten[(Abs[
       fft[[w/2 - windowSize ;; w/2 + windowSize, 
         h/2 - windowSize ;; h/2 + windowSize]]])]]
   ), {r, 0, 10, 0.5}]

Result in a logarithmic plot:

The 5 lines represent the 5 test images, the X axis represents the Gaussian filter radius. The graphs are decreasing, so the FFT is a good measure for sharpness.

This is the code for the "highest LoG" blurriness estimator: It simply applies an LoG filter and returns the brightest pixel in the filter result:

testLaplacian[img_] := Table[
  (
   blurred = GaussianFilter[img, r];
   Max[Flatten[ImageData[LaplacianGaussianFilter[blurred, 1]]]];
   ), {r, 0, 10, 0.5}]

Result in a logarithmic plot:

The spread for the un-blurred images is a little better here (2.5 vs 3.3), mainly because this method only uses the strongest contrast in the image, while the FFT is essentially a mean over the whole image. The functions are also decreasing faster, so it might be easier to set a "blurry" threshold.

Yes; all primitive numeric types default to 0.

However, calculations involving floating-point types (double and float) can be imprecise, so it's usually better to check whether it's close to 0:

if (Math.abs(foo.x) < 2 * Double.MIN_VALUE)

You need to pick a margin of error, which is not simple.

This is Oracle bug, memory leak in shared_pool, most likely db managing lots of partitions. Solution: In my opinion patch not exists, check with oracle support. You can try with subpools or en(de)able AMM ...

Saty described the differences between them. For your practice, you can use datetime in order to keep the output of NOW().

For example:

CREATE TABLE Orders
(
  OrderId int NOT NULL,
  ProductName varchar(50) NOT NULL,
  OrderDate datetime NOT NULL DEFAULT NOW(),
  PRIMARY KEY (OrderId)
)

You can read more at w3schools.

imgDics = (ImageView) v.findViewById(R.id.img_player_tab2_dics);
    imgDics.setOnClickListener(onPlayer2Click);
    anim = new RotateAnimation(0f, 360f,
            Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
                            0.5f);
    anim.setInterpolator(new LinearInterpolator());
    anim.setRepeatCount(Animation.INFINITE);
    anim.setDuration(4000);

    // Start animating the image
    imgDics.startAnimation(anim);

The easiest way is to have a batch file with:

Looking at your output maybe the following query can work, give it a try:

SELECT * FROM tablename
WHERE id IN
(SELECT MIN(id) FROM tablename GROUP BY EmailAddress)

This will select only one row for each distinct email address, the row with the minimum id which is what your result seems to portray

The pathlib library (included with >= Python 3.4) makes it very concise and intuitive to append the path of the parent directory to the PYTHONPATH:

import sys
from pathlib import Path
sys.path.append(str(Path('.').absolute().parent))

Put your jQuery function in

$(document).ready(function(){

});

It's surely solved.

Just for completeness, you can also use ORA_DATABASE_NAME.

It might be worth noting that not all of the methods give you the same output:

SQL> select sys_context('userenv','db_name') from dual;

SYS_CONTEXT('USERENV','DB_NAME')
--------------------------------------------------------------------------------
orcl

SQL> select ora_database_name from dual;

ORA_DATABASE_NAME
--------------------------------------------------------------------------------
ORCL.XYZ.COM

SQL> select * from global_name;

GLOBAL_NAME
--------------------------------------------------------------------------------
ORCL.XYZ.COM

Imagine the DOM (HTML page) as a tree right. The HTML elements are the nodes of this tree.

The append() adds a new node to the child of the node you called it on.

Example:$("#mydiv").append("<p>Hello there</p>") 

creates a child node <p> to <div>

The after() adds a new node as a sibling or at the same level or child to the parent of the node you called it on.

With Oracle 12c (June 2013), you are able to use it like the following.

SELECT * FROM   MYTABLE
--ORDER BY COLUMNNAME -OPTIONAL          
OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY

Add "babel-preset-react"

npm install babel-preset-react

and add "presets" option to babel-loader in your webpack.config.js

(or you can add it to your .babelrc or package.js: http://babeljs.io/docs/usage/babelrc/)

Here is an example webpack.config.js:

{ 
    test: /\.jsx?$/,         // Match both .js and .jsx files
    exclude: /node_modules/, 
    loader: "babel", 
    query:
      {
        presets:['react']
      }
}

Recently Babel 6 was released and there was a major change: https://babeljs.io/blog/2015/10/29/6.0.0

If you are using react 0.14, you should use ReactDOM.render() (from require('react-dom')) instead of React.render(): https://facebook.github.io/react/blog/#changelog

UPDATE 2018

Rule.query has already been deprecated in favour of Rule.options. Usage in webpack 4 is as follows:

npm install babel-loader babel-preset-react

Then in your webpack configuration (as an entry in the module.rules array in the module.exports object)

{
    test: /\.jsx?$/,
    exclude: /node_modules/,
    use: [
      {
        loader: 'babel-loader',
        options: {
          presets: ['react']
        }
      }
    ],
  }

There is a package called eclipse-cdt in the Ubuntu 12.10 repositories, this is what you want. If you haven't got g++ already, you need to install that as well, so all you need is:

sudo apt-get install eclipse eclipse-cdt g++

Whether you messed up your system with your previous installation attempts depends heavily on how you did it. If you did it the safe way for trying out new packages not from repositories (i.e., only installed in your home folder, no sudos blindly copied from installation manuals...) you're definitely fine. Otherwise, you may well have thousands of stray files all over your file system now. In that case, run all uninstall scripts you can find for the things you installed, then install using apt-get and hope for the best.

$str = str_replace(' ','',$str);

Or, replace with underscore, & nbsp; etc etc.

To get callback on LocationChange

Define an interface

public interface LocationCallback {
public void locationChanged(Location location);
}

Callback in your Activity

public static LocationCallback callback;
public void getUserLocation() {

    callback = new LocationCallback() {
        @Override
        public void locationChanged(Location location) {
            Toast.makeText(getApplicationContext(), location.getLatitude() + "," + location.getLongitude(), Toast.LENGTH_SHORT).show();
        }
    };

    Intent service_intent = new Intent(this, GPSService.class);
    startService(service_intent);

}

Change onLocationChange Method to

@Override
    public void onLocationChanged(Location location) {
        Log.e(TAG, "onLocationChanged: " + location);
        MapsActivity.callback.locationChanged(location);
        mLastLocation.set(location);
    }

With out knowing exactly what your trying to accomplish here its hard to say but if your spending the time to solve this problem with javascript an AJAX request is going to be your best bet. However if you'd like to do it completely in PHP put this at the end of your script, and you should be set.

if(isset($_SERVER['HTTP_REFERER'])){
    header("Location: " . $_SERVER['HTTP_REFERER']);    
} else {
    echo "An Error";
}

This will still cause the page to change, twice, but the user will end on the page initiating the request. This is not even close to the right way to do this, and I highly recommend using an AJAX request, but it will get the job done.

You are using datetimepicker when it should be datepicker. As per the docs. Try this and it should work.

<script type="text/javascript">
  $(function () {

The head command can get the first n lines. Variations are:

head -7 file
head -n 7 file
head -7l file

which will get the first 7 lines of the file called "file". The command to use depends on your version of head. Linux will work with the first one.

To append lines to the end of the same file, use:

echo 'first line to add' >>file
echo 'second line to add' >>file
echo 'third line to add' >>file

or:

echo 'first line to add
second line to add
third line to add' >>file

to do it in one hit.

So, tying these two ideas together, if you wanted to get the first 10 lines of the input.txt file to output.txt and append a line with five "=" characters, you could use something like:

( head -10 input.txt ; echo '=====' ) > output.txt

In this case, we do both operations in a sub-shell so as to consolidate the output streams into one, which is then used to create or overwrite the output file.

Normally Python throws NameError if the variable is not defined:

>>> d[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'd' is not defined

However, you've managed to stumble upon a name that already exists in Python.

Because dict is the name of a built-in type in Python you are seeing what appears to be a strange error message, but in reality it is not.

The type of dict is a type. All types are objects in Python. Thus you are actually trying to index into the type object. This is why the error message says that the "'type' object is not subscriptable."

>>> type(dict)
<type 'type'>
>>> dict[0]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'type' object is not subscriptable

Note that you can blindly assign to the dict name, but you really don't want to do that. It's just going to cause you problems later.

>>> dict = {1:'a'}
>>> type(dict)
<class 'dict'>
>>> dict[1]
'a'

The true source of the problem is that you must assign variables prior to trying to use them. If you simply reorder the statements of your question, it will almost certainly work:

d = {1: "walk1.png", 2: "walk2.png", 3: "walk3.png"}
m1 = pygame.image.load(d[1])
m2 = pygame.image.load(d[2])
m3 = pygame.image.load(d[3])
playerxy = (375,130)
window.blit(m1, (playerxy))

In the case where you handle the auth yourself (i.e don't use a provider like Auth0), the following may work:

1. Issue JWT token with relatively short expiry, say 15min.
2. Application checks token expiry date before any transaction requiring a token (token contains expiry date). If token has expired, then it first asks API to 'refresh' the token (this is done transparently to the UX).
3. API gets token refresh request, but first checks user database to see if a 'reauth' flag has been set against that user profile (token can contain user id). If the flag is present, then the token refresh is denied, otherwise a new token is issued.
4. Repeat.

The 'reauth' flag in the database backend would be set when, for example, the user has reset their password. The flag gets removed when the user logs in next time.

In addition, let's say you have a policy whereby a user must login at least once every 72hrs. In that case, your API token refresh logic would also check the user's last login date from the user database and deny/allow the token refresh on that basis.

Via composer installing specific version 7.*

composer create-project --prefer-dist laravel/laravel:^7.0 project_name

To install specific version 6.* and below use the following command:

composer create-project --prefer-dist laravel/laravel project_name "6.*"

In your input tag, place the following:

HI im going to leave this here cz i cant comment due to restrictions but i found AlexFitiskin's answer perfect, but a small correction was needed

document.getElementById('here').innerHTML = data.name; 

This needed to be changed to

document.getElementById('here').innerHTML = data.n;

I know that after five years the owner of the post will not find it of any importance but this is for people who might come across in the future .

Try this instead:

$journalName = str_replace(' ', '_', $journalName);

to remove white space

An undocumented feature of the formData field that request implements is the ability to pass options to the form-data module it uses:

request({
  url: 'http://example.com',
  method: 'POST',
  formData: {
    'regularField': 'someValue',
    'regularFile': someFileStream,
    'customBufferFile': {
      value: fileBufferData,
      options: {
        filename: 'myfile.bin'
      }
    }
  }
}, handleResponse);

This is useful if you need to avoid calling requestObj.form() but need to upload a buffer as a file. The form-data module also accepts contentType (the MIME type) and knownLength options.

This change was added in October 2014 (so 2 months after this question was asked), so it should be safe to use now (in 2017+). This equates to version v2.46.0 or above of request.

I agree with above answers and tips but there is a way to change database name with phpmyadmin

Renaming the Database From cPanel, click on phpMyAdmin. (It should open in a new tab.) Click on the database you wish to rename in the left hand column. Click on the Operations tab. Where it says "Rename database to:" enter the new database name. Click the Go button. When it asks you to want to create the new database and drop the old database, click OK to proceed. (This is a good time to make sure you spelled the new name correctly.) Once the operation is complete, click OK when asked if you want to reload the database.

here's the video tutorial:

http://support.hostgator.com/articles/specialized-help/technical/phpmyadmin/how-to-rename-a-database-in-phpmyadmin

It's as simple as this: the JBoss docs are not 100% perfectly well-maintained. Go with what the JavaDoc says: buildSessionFactory(ServiceRegistry serviceRegistry).

I tried all the answers here but nothing seemed to work. Restarted my computer first then ran mvn clean install -U. That solved my problem.

You can use this snippet :-D

using System;
using System.Reflection;

public static class EnumUtils
{
    public static T GetDefaultValue<T>()
        where T : struct, Enum
    {
        return (T)GetDefaultValue(typeof(T));
    }

    public static object GetDefaultValue(Type enumType)
    {
        var attribute = enumType.GetCustomAttribute<DefaultValueAttribute>(inherit: false);
        if (attribute != null)
            return attribute.Value;

        var innerType = enumType.GetEnumUnderlyingType();
        var zero = Activator.CreateInstance(innerType);
        if (enumType.IsEnumDefined(zero))
            return zero;

        var values = enumType.GetEnumValues();
        return values.GetValue(0);
    }
}

Example:

using System;

public enum Enum1
{
    Foo,
    Bar,
    Baz,
    Quux
}
public enum Enum2
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 0
}
public enum Enum3
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}
[DefaultValue(Enum4.Bar)]
public enum Enum4
{
    Foo  = 1,
    Bar  = 2,
    Baz  = 3,
    Quux = 4
}

public static class Program 
{
    public static void Main() 
    {
        var defaultValue1 = EnumUtils.GetDefaultValue<Enum1>();
        Console.WriteLine(defaultValue1); // Foo

        var defaultValue2 = EnumUtils.GetDefaultValue<Enum2>();
        Console.WriteLine(defaultValue2); // Quux

        var defaultValue3 = EnumUtils.GetDefaultValue<Enum3>();
        Console.WriteLine(defaultValue3); // Foo

        var defaultValue4 = EnumUtils.GetDefaultValue<Enum4>();
        Console.WriteLine(defaultValue4); // Bar
    }
}

For UTC:

string unixTimestamp = Convert.ToString((int)DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);

For local system:

string unixTimestamp = Convert.ToString((int)DateTime.Now.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);

Check out CUDA by NVidia, IMO it's the easiest platform to do GPU programming. There are tons of cool materials to read. http://www.nvidia.com/object/cuda_home.html

Hello world would be to do any kind of calculation using GPU.

Hope that helps.

You can also take a look at the below Java code. Following codes does not use any "built-in" methods.

/**
 * Remove all characters from an alphanumeric string.
 */
public class RemoveCharFromAlphanumerics {

    public static void main(String[] args) {

        String inp = "01239Debashish123Pattn456aik";

        char[] out = inp.toCharArray();

        int totint=0;

        for (int i = 0; i < out.length; i++) {
            System.out.println(out[i] + " : " + (int) out[i]);
            if ((int) out[i] >= 65 && (int) out[i] <= 122) {
                out[i] = ' ';
            }
            else {
                totint+=1;
            }

        }

        System.out.println(String.valueOf(out));
        System.out.println(String.valueOf("Length: "+ out.length));

        for (int c=0; c<out.length; c++){

            System.out.println(out[c] + " : " + (int) out[c]);

            if ( (int) out[c] == 32) {
                System.out.println("Its Blank");
                 out[c] = '\'';
            }

        }

        System.out.println(String.valueOf(out));

        System.out.println("**********");
        System.out.println("**********");
        char[] whitespace = new char[totint];
        int t=0;
        for (int d=0; d< out.length; d++) {

            int fst =32;



            if ((int) out[d] >= 48 && (int) out[d] <=57 ) {

                System.out.println(out[d]);
                whitespace[t]= out[d];
                t+=1;

            }

        }

        System.out.println("**********");
        System.out.println("**********");

        System.out.println("The String is: " + String.valueOf(whitespace));

    }
}

Input:

String inp = "01239Debashish123Pattn456aik";

Output:

The String is: 01239123456

It is used in the stack unwiding tables, which you can see for instance in the assembly output of my answer to another question. As mentioned on that answer, its use is defined by the Itanium C++ ABI, where it is called the Personality Routine.

The reason it "works" by defining it as a global NULL void pointer is probably because nothing is throwing an exception. When something tries to throw an exception, then you will see it misbehave.

Of course, if nothing is using exceptions, you can disable them with -fno-exceptions (and if nothing is using RTTI, you can also add -fno-rtti). If you are using them, you have to (as other answers already noted) link with g++ instead of gcc, which will add -lstdc++ for you.

Returning the whole object on an update would not seem very relevant, but I can hardly see why returning the whole object when it is created would be a bad practice in a normal use case. This would be useful at least to get the ID easily and to get the timestamps when relevant. This is actually the default behavior got when scaffolding with Rails.

I really do not see any advantage to returning only the ID and doing a GET request after, to get the data you could have got with your initial POST.

Anyway as long as your API is consistent I think that you should choose the pattern that fits your needs the best. There is not any correct way of how to build a REST API, imo.

There are several problems.

One is of style; always capitalize class names. This is a universally observed Java convention. Failing to do so confuses other programmers.

Secondly, the line

System.out.println(boolean isLeapYear);

is a syntax error. Delete it.

Thirdly.

You never call the function from your main routine. That is why you never see any reply to the input.

(Copied from this question)

In cases where I have not had control over the incoming JSON (and so cannot ensure that it includes a $type property) I have written a custom converter that just allows you to explicitly specify the concrete type:

public class Model
{
    [JsonConverter(typeof(ConcreteTypeConverter<Something>))]
    public ISomething TheThing { get; set; }
}

This just uses the default serializer implementation from Json.Net whilst explicitly specifying the concrete type.

An overview are available on this blog post. Source code is below:

public class ConcreteTypeConverter<TConcrete> : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        //assume we can convert to anything for now
        return true;
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        //explicitly specify the concrete type we want to create
        return serializer.Deserialize<TConcrete>(reader);
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        //use the default serialization - it works fine
        serializer.Serialize(writer, value);
    }
}

By utilizing string operations of JS one can do as follows;

0b1111011.toString(2).split(/0|(?=.)/).length // returns 6

or

0b1111011.toString(2).replace("0","").length  // returns 6

We can easily create and export/download the excel file with any separator (in this answer I am using the comma separator) using javascript. I am not using any external package for creating the excel file.

Remove these two lines:

xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");

XMLHttpRequest isn't allowed to set these headers, they are being set automatically by the browser. The reason is that by manipulating these headers you might be able to trick the server into accepting a second request through the same connection, one that wouldn't go through the usual security checks - that would be a security vulnerability in the browser.

No. I don't see any advantage. Second one is more straitforward.

btw: Second style is found in every corners of JDK source.

Yet another solution.

Add ErrorControllers or static page to with 404 error information.

Modify your web.config (in case of controller).

<system.web>
    <customErrors mode="On" >
       <error statusCode="404" redirect="~/Errors/Error404" />
    </customErrors>
</system.web>

Or in case of static page

<system.web>
    <customErrors mode="On" >
        <error statusCode="404" redirect="~/Static404.html" />
    </customErrors>
</system.web>

This will handle both missed routes and missed actions.

You might be better off using the Properties Service as you can use these as a kind of persistent global variable.

click 'file > project properties > project properties' to set a key value, or you can use

PropertiesService.getScriptProperties().setProperty('mykey', 'myvalue');

The data can be retrieved with

var myvalue = PropertiesService.getScriptProperties().getProperty('mykey');

You need to prevent the default behaviour. You can either use e.preventDefault() or return false; In this case, the best thing is, you can use return false; here:

<form onsubmit="completeAndRedirect(); return false;">

To resolve problem go to the MDaemon-->setup-->Miscellaneous options-->Server-->SMTP Server Checks commands and headers for RFC Compliance

Little Edit

Try adding

return new JavascriptResult() { Script = "alert('Successfully registered');" };

in place of

return RedirectToAction("Index");

There are two ways to handle exceptions in pytest:

1. Using pytest.raises to write assertions about raised exceptions
2. Using @pytest.mark.xfail

1. Using pytest.raises

From the docs:

In order to write assertions about raised exceptions, you can use pytest.raises as a context manager

Examples:

Asserting just an exception:

import pytest


def test_zero_division():
    with pytest.raises(ZeroDivisionError):
        1 / 0

with pytest.raises(ZeroDivisionError) says that whatever is in the next block of code should raise a ZeroDivisionError exception. If no exception is raised, the test fails. If the test raises a different exception, it fails.

If you need to have access to the actual exception info:

import pytest

def f():
    f()

def test_recursion_depth():
    with pytest.raises(RuntimeError) as excinfo:
        f()
    assert "maximum recursion" in str(excinfo.value)

excinfo is a ExceptionInfo instance, which is a wrapper around the actual exception raised. The main attributes of interest are .type, .value and .traceback.

2. Using @pytest.mark.xfail

It is also possible to specify a raises argument to pytest.mark.xfail.

import pytest

@pytest.mark.xfail(raises=IndexError)
def test_f():
    l = [1, 2, 3]
    l[10]

@pytest.mark.xfail(raises=IndexError) says that whatever is in the next block of code should raise an IndexError exception. If an IndexError is raised, test is marked as xfailed (x). If no exception is raised, the test is marked as xpassed (X). If the test raises a different exception, it fails.

Notes:

• Using pytest.raises is likely to be better for cases where you are testing exceptions your own code is deliberately raising, whereas using @pytest.mark.xfail with a check function is probably better for something like documenting unfixed bugs or bugs in dependencies.

• You can pass a match keyword parameter to the context-manager (pytest.raises) to test that a regular expression matches on the string representation of an exception. (see more)

my 2c:

I tried both with n and with nvm on Linux Ubuntu 12.04 LTS, in order to update node from v0.8.25 to v0.10.22.

The first one was successfully completed, but the command 'which node' resulted in the old v0.8.25.
The second one was successfully completed and the same command resulted in v.0.10.22.

If you're struggling with such an issue using Lollipop (Android 5.*) probably you guys should do one simple step that I'd done before my ADB (I use Ubuntu) got my phone:

Change USB PC connection type to "Send images(PTP)" (before I've been using "Media device(MTP)")

Just like this:

And don't forget to activate checkbox "USB debugging".

Improving Daniel Wolf answer even further you could stack on another IEnumerable to avoid multiple iterations and lambdas such as:

var elements = new[] { "A", "B", "C" };
foreach (var e in elements.Detailed())
{
    if (!e.IsLast) {
        Console.WriteLine(e.Value);
    } else {
        Console.WriteLine("Last one: " + e.Value);
    }
}

The extension method implementation:

public static class EnumerableExtensions {
    public static IEnumerable<IterationElement<T>> Detailed<T>(this IEnumerable<T> source)
    {
        if (source == null)
            throw new ArgumentNullException(nameof(source));

        using (var enumerator = source.GetEnumerator())
        {
            bool isFirst = true;
            bool hasNext = enumerator.MoveNext();
            int index = 0;
            while (hasNext)
            {
                T current = enumerator.Current;
                hasNext = enumerator.MoveNext();
                yield return new IterationElement<T>(index, current, isFirst, !hasNext);
                isFirst = false;
                index++;
            }
        }
    }

    public struct IterationElement<T>
    {
        public int Index { get; }
        public bool IsFirst { get; }
        public bool IsLast { get; }
        public T Value { get; }

        public IterationElement(int index, T value, bool isFirst, bool isLast)
        {
            Index = index;
            IsFirst = isFirst;
            IsLast = isLast;
            Value = value;
        }
    }
}

If you want to set environment variables permanently in Git-Bash, you have two options:

1. Set a regular Windows environment variable. Git-bash gets all existing Windows environment variables at startupp.

2. Set up env variables in .bash_profile file.

.bash_profile is by default located in a user home folder, like C:\users\userName\git-home\.bash_profile. You can change the path to the bash home folder by setting HOME Windows environment variable.

.bash_profile file uses the regular Bash syntax and commands

# Export a variable in .bash_profile
export DIR=c:\dir
# Nix path style works too
export DIR=/c/dir

# And don't forget to add quotes if a variable contains whitespaces
export ANOTHER_DIR="c:\some dir"

1. What is Express.js?

Express.js is a Node.js web application server framework, designed for building single-page, multi-page, and hybrid web applications. It is the de facto standard server framework for node.js.

Frameworks built on Express.

Several popular Node.js frameworks are built on Express:

LoopBack: Highly-extensible, open-source Node.js framework for quickly creating dynamic end-to-end REST APIs.

Sails: MVC framework for Node.js for building practical, production-ready apps.

Kraken: Secure and scalable layer that extends Express by providing structure and convention.

MEAN: Opinionated fullstack JavaScript framework that simplifies and accelerates web application development.

2. What is the purpose of it with Node.js?
3. Why do we actually need Express.js? How it is useful for us to use with Node.js?

Express adds dead simple routing and support for Connect middleware, allowing many extensions and useful features.

For example,

• Want sessions? It's there
• Want POST body / query string parsing? It's there
• Want easy templating through jade, mustache, ejs, etc? It's there
• Want graceful error handling that won't cause the entire server to crash?

For osX Mavericks Users you can install the ipa-file with the Apple Configurator. (Instead of the iPhone configuration utility, which crashes on OSX 10.9)

It's easy to do multiline replace in Notepad++. You have to use \n to represent the newline in your string, and it works for both search and replace strings. You have to make sure to select "Extended" search mode in the bottom left corner of the search window.

I found a good article describing the features here: http://markantoniou.blogspot.com/2008/06/notepad-how-to-use-regular-expressions.html

The innerHTML of your iframe is blank because your iframe tag doesn't surround any content in the parent document. In order to get the content from the page referred to by the iframe's src attribute, you need to access the iframe's contentDocument property. An exception will be thrown if the src is from a different domain though. This is a security feature that prevents you from executing arbitrary JavaScript on someone else's page, which would create a cross-site scripting vulnerability. Here is some example code the illustrates what I'm talking about:

<script src="http://prototypejs.org/assets/2009/8/31/prototype.js" type="text/javascript"></script>

<h1>Parent</h1>

<script type="text/javascript">
function on_load(iframe) {
  try {
    // Displays the first 50 chars in the innerHTML of the
    // body of the page that the iframe is showing.
    // EDIT 2012-04-17: for wider support, fallback to contentWindow.document
    var doc = iframe.contentDocument || iframe.contentWindow.document;
    alert(doc.body.innerHTML.substring(0, 50));
  } catch (e) {
    // This can happen if the src of the iframe is
    // on another domain
    alert('exception: ' + e);
  }
}

<h1>Child</h1>

<a href="http://www.google.com/">Google</a>

In the spirit of providing functionality, go to your .profile or .bashrc file located at /home/usr/ and at the bottom add the line:

alias enw='emacs -nw'

Now each time you open a terminal session you just type, for example, enw and you have the Emacs no-window option with three letters :).

This is what helped me:

1. Create a new branch with the existing one. Let's call the existing one branch_old and new as branch_new.

2. Reset branch_new to a stable state, when you did not have any problem commit at all. For example, to put it at your local master's level do the following:

   git reset —hard master git push —force origin

3. cherry-pick the commits from branch_old into branch_new

4. git push

I am fairly new to Javascript. But this is what I understood: JSON.parse() returns SyntaxError exceptions when invalid JSON is provided as its first parameter. So. It would be better to catch that exception as such like as follows:

try {
    let sData = `
        {
            "id": "1",
            "name": "UbuntuGod",
        }
    `;
    console.log(JSON.parse(sData));
} catch (objError) {
    if (objError instanceof SyntaxError) {
        console.error(objError.name);
    } else {
        console.error(objError.message);
    }
}

The reason why I made the words "first parameter" bold is that JSON.parse() takes a reviver function as its second parameter.

A simple solution to generate unique identification is to use time token and add random number to it. I prefer to prefix it with "uuid-".

Below function will generate random string of type: uuid-14d93eb1b9b4533e6. One doesn't need to generate 32 chars random string. 16 char random string is more than sufficient in this case to provide the unique UUIDs in javascript.

var createUUID = function() {
  return"uuid-"+((new Date).getTime().toString(16)+Math.floor(1E7*Math.random()).toString(16));
}

@Daniel made a comment on the question in 2012 about the lack of support for the CSS3 features: top-center & bottom-center.

Well, In Chrome 73+, the following snippet works, where header and footer are <header></header> and <footer></footer> elements defined within the page.

@page {
    @top-center { content: element(header) }
}
@page { 
    @bottom-center { content: element(footer) }
}

You also need to make sure you have your php.ini file include the following set or errors will go only to the log that is set by default or specified in the virtual host's configuration.

display_errors = On

The php.ini file is where base settings for all PHP on your server, however these can easily be overridden and altered any place in the PHP code and effect everything following that change. A good check is to add the display_errors directive to your php.ini file. If you don't see an error, but one is being logged, insert this at the top of the file causing the error:

ini_set('display_errors', 1);
error_reporting(E_ALL);

If this works then something earlier in your code is disabling error display.

No, the only thing that needs to be modified for an Anaconda environment is the PATH (so that it gets the right Python from the environment bin/ directory, or Scripts\ on Windows).

The way Anaconda environments work is that they hard link everything that is installed into the environment. For all intents and purposes, this means that each environment is a completely separate installation of Python and all the packages. By using hard links, this is done efficiently. Thus, there's no need to mess with PYTHONPATH because the Python binary in the environment already searches the site-packages in the environment, and the lib of the environment, and so on.

The following parser reads a file, parses it into a generic JsonElement, using Google's JsonParser.parse method, and then converts all the items in the generated JSON into a native Java List<object> or Map<String, Object>.

I had a similar issue on a client site where the client required a authority certificate to be installed automatically for 2000+ windows users.

I created the following .vbs script to import the certificate into the current logged on users firefox cert store.

The script needs to be put in the directory containing a working copy of certutil.exe (the nss version) but programatically determines the firefox profiles location.

In Python3.6, the StringIO and cStringIO modules are gone, you should use io.StringIO instead.So you should do this like the first answer:

import sys
from io import StringIO

old_stdout = sys.stdout
old_stderr = sys.stderr
my_stdout = sys.stdout = StringIO()
my_stderr = sys.stderr = StringIO()

# blah blah lots of code ...

sys.stdout = self.old_stdout
sys.stderr = self.old_stderr

// if you want to see the value of redirect output, be sure the std output is turn back
print(my_stdout.getvalue())
print(my_stderr.getvalue())

my_stdout.close()
my_stderr.close()

It exists, but it's hard to search for. I think most people call it the "splat" operator.

It's in the documentation as "Unpacking argument lists".

You'd use it like this: foo(*values). There's also one for dictionaries:

d = {'a': 1, 'b': 2}
def foo(a, b):
    pass
foo(**d)

Use the put method: https://developer.android.com/reference/org/json/JSONObject.html

JSONObject person =  jsonArray.getJSONObject(0).getJSONObject("person");
person.put("name", "Sammie");

This is not a question about make, it is a question about the semantic of the #include directive.

The problem is, that there is no file at the path "../StdCUtil/StdCUtil/split.h". This is the path that results when the compiler combines the include path "../StdCUtil" with the relative path from the #include directive "StdCUtil/split.h".

To fix this, just use -I.. instead of -I../StdCUtil.

Start each row with \"-\" to create bullet list.

Following two configuration is working for me.

From the comments:

import msvcrt # built-in module

def kbfunc():
    return ord(msvcrt.getch()) if msvcrt.kbhit() else 0

Thanks for the help. I ended up writing a C DLL called PyKeyboardAccess.dll and accessing the crt conio functions, exporting this routine:

#include <conio.h>

int kb_inkey () {
   int rc;
   int key;

   key = _kbhit();

   if (key == 0) {
      rc = 0;
   } else {
      rc = _getch();
   }

   return rc;
}

And I access it in python using the ctypes module (built into python 2.5):

import ctypes
import time

#
# first, load the DLL
#


try:
    kblib = ctypes.CDLL("PyKeyboardAccess.dll")
except:
    raise ("Error Loading PyKeyboardAccess.dll")


#
# now, find our function
#

try:
    kbfunc = kblib.kb_inkey
except:
    raise ("Could not find the kb_inkey function in the dll!")


#
# Ok, now let's demo the capability
#

while 1:
    x = kbfunc()

    if x != 0:
        print "Got key: %d" % x
    else:
        time.sleep(.01)

I had the same problem with a file that I've created on my mac. If I try to run it in a shell with ./filename I got the file not found error message. I think that something was wrong with the file.

what I've done:

open a ssh session to the server
cat filename
copy the output to the clipboard
rm filename
touch filename
vi filename
i for insert mode
paste the content from the clipboard
ESC to end insert mode
:wq!

This worked for me.

This should be pretty efficient, and easier than getting the whole TPL Dataflow working:

var customers = await ids.SelectAsync(async i =>
{
    ICustomerRepo repo = new CustomerRepo();
    return await repo.GetCustomer(i);
});

...

public static async Task<IList<TResult>> SelectAsync<TSource, TResult>(this IEnumerable<TSource> source, Func<TSource, Task<TResult>> selector, int maxDegreesOfParallelism = 4)
{
    var results = new List<TResult>();

    var activeTasks = new HashSet<Task<TResult>>();
    foreach (var item in source)
    {
        activeTasks.Add(selector(item));
        if (activeTasks.Count >= maxDegreesOfParallelism)
        {
            var completed = await Task.WhenAny(activeTasks);
            activeTasks.Remove(completed);
            results.Add(completed.Result);
        }
    }

    results.AddRange(await Task.WhenAll(activeTasks));
    return results;
}

John's answer is correct. When I'm dealing with params I also need URLSearchParams interface:

this.props.history.push({
    pathname: '/client',
    search: "?" + new URLSearchParams({clientId: clientId}).toString()
})

You might also need to wrap your component with a withRouter HOC eg. export default withRouter(YourComponent);.

You can't break from a Groovy each loop, but you can break from a java "enhanced" for loop.

def a = [1, 2, 3, 4, 5, 6, 7]

for (def i : a) {
    if (i < 2)
        continue
    if (i > 5)
        break
    println i
}

Output:

2
3
4
5

This might not fit for absolutely every situation but it's helped for me :)

In configuration class

@Configuration
@PropertySource("classpath:/com/myco/app.properties")
public class AppConfig {
   @Autowired
   Environment env;

   @Bean
   public TestBean testBean() {
       TestBean testBean = new TestBean();
       testBean.setName(env.getProperty("testbean.name"));
       return testBean;
   }
}

cp -R t1/ t2

The trailing slash on the source directory changes the semantics slightly, so it copies the contents but not the directory itself. It also avoids the problems with globbing and invisible files that Bertrand's answer has (copying t1/* misses invisible files, copying `t1/* t1/.*' copies t1/. and t1/.., which you don't want).

Just to share, I've developed my own script to do it. Feel free to use it. It generates "SELECT" statements that you can then run on the tables to generate the "INSERT" statements.

AFAIK, you have to convert it to grayscale and then threshold it to binary.

1. Read the image as a grayscale image If you're reading the RGB image from disk, then you can directly read it as a grayscale image, like this:

// C
IplImage* im_gray = cvLoadImage("image.jpg",CV_LOAD_IMAGE_GRAYSCALE);

// C++ (OpenCV 2.0)
Mat im_gray = imread("image.jpg",CV_LOAD_IMAGE_GRAYSCALE);

2. Convert an RGB image im_rgb into a grayscale image: Otherwise, you'll have to convert the previously obtained RGB image into a grayscale image

// C
IplImage *im_rgb  = cvLoadImage("image.jpg");
IplImage *im_gray = cvCreateImage(cvGetSize(im_rgb),IPL_DEPTH_8U,1);
cvCvtColor(im_rgb,im_gray,CV_RGB2GRAY);

// C++
Mat im_rgb  = imread("image.jpg");
Mat im_gray;
cvtColor(im_rgb,im_gray,CV_RGB2GRAY);

3. Convert to binary You can use adaptive thresholding or fixed-level thresholding to convert your grayscale image to a binary image.

E.g. in C you can do the following (you can also do the same in C++ with Mat and the corresponding functions):

// C
IplImage* im_bw = cvCreateImage(cvGetSize(im_gray),IPL_DEPTH_8U,1);
cvThreshold(im_gray, im_bw, 128, 255, CV_THRESH_BINARY | CV_THRESH_OTSU);

// C++
Mat img_bw = im_gray > 128;

In the above example, 128 is the threshold.

4. Save to disk

// C
cvSaveImage("image_bw.jpg",img_bw);

// C++
imwrite("image_bw.jpg", img_bw);

There is no bound checking in array in C programming. If you declare array as

int arr[50];

Then you can even write as

arr[51] = 10;

The compiler would not throw an error. Hope this answers your question.

Most modern RDBMSs support the INFORMATION_SCHEMA schema. If yours supports that, then you want either INFORMATION_SCHEMA.TABLE_CONSTRAINTS or INFORMATION_SCHEMA.KEY_COLUMN_USAGE, or maybe both.

To see if yours supports it is as simple as running

select count(*) from INFORMATION_SCHEMA.TABLE_CONSTRAINTS

EDIT: SQL Server does have INFORMATION_SCHEMA, and it's easier to use than their vendor-specific tables, so just go with it.

In native LINQ you may use combination of Contains/StartsWith/EndsWith or RegExp.

In LINQ2SQL use method SqlMethods.Like()

    from i in db.myTable
    where SqlMethods.Like(i.field, "tra%ata")
    select i

add Assembly: System.Data.Linq (in System.Data.Linq.dll) to use this feature.

Starting with Bootstrap v3.3.0 you can use .media-left and .media-body

<div class="media">
    <span class="media-left">
        <img src="../site/img/success32.png" alt="...">
    </span>
    <div class="media-body">
        <h3 class="media-heading">Experience</h3>
        ...
    </div>
</div>

The answer, as given, is to use format-patch but since the question was how to cherry-pick from another folder, here is a piece of code to do just that:

$ git --git-dir=../<some_other_repo>/.git \
format-patch -k -1 --stdout <commit SHA> | \
git am -3 -k

(explanation from @cong ma)

The git format-patch command creates a patch from some_other_repo's commit specified by its SHA (-1 for one single commit alone). This patch is piped to git am, which applies the patch locally (-3 means trying the three-way merge if the patch fails to apply cleanly). Hope that explains.

string substr ( string $string , int $start [, int $length ] )

http://php.net/manual/en/function.substr.php

Check out setParseBigDecimal in DecimalFormat. With this setter, parse will return a BigDecimal for you.

Here is another dirty hack :)

.application-title > img {
display: none;
}

.application-title::before {
content: url(path/example.jpg);
}

Try following code, it works in my project:

//start ajax request
$.ajax({
    url: "data.json",
    //force to handle it as text
    dataType: "text",
    success: function(data) {

        //data downloaded so we call parseJSON function 
        //and pass downloaded data
        var json = $.parseJSON(data);
        //now json variable contains data in json format
        //let's display a few items
        for (var i=0;i<json.length;++i)
        {
            $('#results').append('<div class="name">'+json[i].name+'</>');
        }
    }
});

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

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

The XML configuration of Spring is composed of Beans and Beans are basically classes. They're just POJOs that we use inside of our ApplicationContext. Defining Beans can be thought of as replacing the keyword new. So wherever you are using the keyword new in your application something like:

MyRepository myRepository =new MyRepository ();

Where you're using that keyword new that's somewhere you can look at removing that configuration and placing it into an XML file. So we will code like this:

<bean name="myRepository " 
      class="com.demo.repository.MyRepository " />

Now we can simply use Setter Injection/ Constructor Injection. I'm using Setter Injection.

public class MyServiceImpl implements MyService {
    private MyRepository myRepository;
    public void setMyRepository(MyRepository myRepository)
        {
    this.myRepository = myRepository ;
        }
public List<Customer> findAll() {
        return myRepository.findAll();
    }
}

Exemple, for :

<div id="myBlock" style="margin: 10px 0px 15px 5px:"></div>

In this js code :

var myMarginTop = $("#myBlock").css("marginBottom");

The var becomes "15px", a string.

If you want an Integer, to avoid NaN (Not a Number), there is multiple ways.

The fastest is to use native js method :

var myMarginTop = parseInt( $("#myBlock").css("marginBottom") );

Select count(*) from table_name into @var1; 
Select @var1;

No one here posted an answer with all of the correct CSS variations, so here it is:

-webkit-touch-callout: none;
-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;

It appears to me that you have two issues here. One is that JFrame does not have a close method, which has been addressed in the other answers.

The other is that you're having trouble referencing your JFrame. Within actionPerformed, super refers to ActionListener. To refer to the JFrame instance there, use MyExtendedJFrame.super instead (you should also be able to use MyExtendedJFrame.this, as I see no reason why you'd want to override the behaviour of dispose or setVisible).

It is called a shebang. It consists of a number sign and an exclamation point character (#!), followed by the full path to the interpreter such as /bin/bash. All scripts under UNIX and Linux execute using the interpreter specified on a first line.

that worked for me after clearing selection, BeginEdit and change the girdview rows and end the Edit Mode.

 if (dgvDetails.RowCount > 0)
                    {
                        dgvDetails.ClearSelection(); 
                        dgvDetails.BeginEdit(true); 
                      
                        foreach (DataGridViewRow dgvr in dgvDetails.Rows)
                        {
                            dgvr.Cells["cellName"].Value = true;
                        }
                        dgvDetails.EndEdit();
                    }

@tasseKATT's Answer is great, but if you don't want to make a directive, why not use $document?

.controller('ExampleController', ['$scope', '$document', function($scope, $document) {
  var dumb = function (id) {
  var queryResult = $document[0].getElementById(id)
  var wrappedID = angular.element(queryResult);
  return wrappedID;
};

PLUNKR

Make use of Parameter Grouping (Laravel 4.2). For your example, it'd be something like this:

Model::where(function ($query) {
    $query->where('a', '=', 1)
          ->orWhere('b', '=', 1);
})->where(function ($query) {
    $query->where('c', '=', 1)
          ->orWhere('d', '=', 1);
});

You must use the labels index you have, here what I do for text classification:

# data labels = [1, 2, 1...]
labels_index = { "website" : 0, "money" : 1 ....} 
# to feed model
label_categories = to_categorical(np.asarray(labels)) 

Then, for predictions:

texts = ["hello, rejoins moi sur skype", "bonjour comment ça va ?", "tu me donnes de l'argent"]

sequences = tokenizer.texts_to_sequences(texts)

data = pad_sequences(sequences, maxlen=MAX_SEQUENCE_LENGTH)

predictions = model.predict(data)

t = 0

for text in texts:
    i = 0
    print("Prediction for \"%s\": " % (text))
    for label in labels_index:
        print("\t%s ==> %f" % (label, predictions[t][i]))
        i = i + 1
    t = t + 1

This gives:

Prediction for "hello, rejoins moi sur skype": 
    website ==> 0.759483
    money ==> 0.037091
    under ==> 0.010587
    camsite ==> 0.114436
    email ==> 0.075975
    abuse ==> 0.002428
Prediction for "bonjour comment ça va ?": 
    website ==> 0.433079
    money ==> 0.084878
    under ==> 0.048375
    camsite ==> 0.036674
    email ==> 0.369197
    abuse ==> 0.027798
Prediction for "tu me donnes de l'argent": 
    website ==> 0.006223
    money ==> 0.095308
    under ==> 0.003586
    camsite ==> 0.003115
    email ==> 0.884112
    abuse ==> 0.007655

The full URL is available as request.url, and the query string is available as request.query_string.decode().

Here's an example:

from flask import request

@app.route('/adhoc_test/')
def adhoc_test():

    return request.query_string

To access an individual known param passed in the query string, you can use request.args.get('param'). This is the "right" way to do it, as far as I know.

ETA: Before you go further, you should ask yourself why you want the query string. I've never had to pull in the raw string - Flask has mechanisms for accessing it in an abstracted way. You should use those unless you have a compelling reason not to.

I have a blog and I had a lot of trouble finding out how to resize my embedded gist. Post manager only allows you to write text, place images and embed HTML code. Blog layout is responsive itself. It's built with Wix. However, embedded HTML is not. I read a lot about how it's impossible to resize components inside body of generated iFrames. So, here is my suggestion:

If you only have one component inside your iFrame, i.e. your gist, you can resize only the gist. Forget about the iFrame.

I had problems with viewport, specific layouts to different user agents and this is what solved my problem:

<script language="javascript" type="text/javascript" src="https://gist.github.com/roliveiravictor/447f994a82238247f83919e75e391c6f.js"></script>

<script language="javascript" type="text/javascript">

function windowSize() {
  let gist = document.querySelector('#gist92442763');

  let isMobile = {
    Android: function() {
        return /Android/i.test(navigator.userAgent)
    },
    BlackBerry: function() {
        return /BlackBerry/i.test(navigator.userAgent)
    },
    iOS: function() {
        return /iPhone|iPod/i.test(navigator.userAgent)
    },
    Opera: function() {
        return /Opera Mini/i.test(navigator.userAgent)
    },
    Windows: function() {
        return /IEMobile/i.test(navigator.userAgent) || /WPDesktop/i.test(navigator.userAgent)
    },
    any: function() {
        return (isMobile.Android() || isMobile.BlackBerry() || isMobile.iOS() || isMobile.Opera() || isMobile.Windows());
    }
};

  if(isMobile.any()) {
    gist.style.width = "36%";
    gist.style.WebkitOverflowScrolling = "touch"
    gist.style.position = "absolute"
  } else {
    gist.style.width = "auto !important";
  }
}

windowSize();

window.addEventListener('onresize', function() {
    windowSize();
});

</script>

<style type="text/css">

.gist-data {
  max-height: 300px;
}

.gist-meta {
  display: none;
}

</style>

The logic is to set gist (or your component) css based on user agent. Make sure to identify your component first, before applying to query selector. Feel free to take a look how responsiveness is working.

I'm not familiar with Wordpress templates, but I'm assuming that headers are sent to the browser by WP before your template is even loaded. Because of that, the common redirection method of:

header("Location: new_url");

won't work. Unless there's a way to force sending headers through a template before WP does anything, you'll need to use some Javascript like so:

<script language="javascript" type="text/javascript">
document.location = "new_url";
</script>

Put that in the section and it'll be run when the page loads. This method won't be instant, and it also won't work for people with Javascript disabled.

Here comes the solution.

Just start ANDROID STUDIO as administrator if you are using a non administrator windows profile!

If your environment variables are correct that will do the trick. Enjoy!

I found this question because I wanted to pose a question why there is a performance impact if one uses nested functions. I ran tests for the following functions using Python 3.2.5 on a Windows Notebook with a Quad Core 2.5 GHz Intel i5-2530M processor

def square0(x):
    return x*x

def square1(x):
    def dummy(y):
        return y*y
    return x*x

def square2(x):
    def dummy1(y):
        return y*y
    def dummy2(y):
        return y*y
    return x*x

def square5(x):
    def dummy1(y):
        return y*y
    def dummy2(y):
        return y*y
    def dummy3(y):
        return y*y
    def dummy4(y):
        return y*y
    def dummy5(y):
        return y*y
    return x*x

I measured the following 20 times, also for square1, square2, and square5:

s=0
for i in range(10**6):
    s+=square0(i)

and got the following results

>>> 
m = mean, s = standard deviation, m0 = mean of first testcase
[m-3s,m+3s] is a 0.997 confidence interval if normal distributed

square? m     s       m/m0  [m-3s ,m+3s ]
square0 0.387 0.01515 1.000 [0.342,0.433]
square1 0.460 0.01422 1.188 [0.417,0.503]
square2 0.552 0.01803 1.425 [0.498,0.606]
square5 0.766 0.01654 1.979 [0.717,0.816]
>>> 

square0 has no nested function, square1 has one nested function, square2 has two nested functions and square5 has five nested functions. The nested functions are only declared but not called.

So if you have defined 5 nested funtions in a function that you don't call then the execution time of the function is twice of the function without a nested function. I think should be cautious when using nested functions.

The Python file for the whole test that generates this output can be found at ideone.

size_t lf = strlen(first);
size_t ls = strlen(second);

char *both = (char*) malloc((lf + ls + 2) * sizeof(char));

strcpy(both, first);

both[lf] = ' ';
strcpy(&both[lf+1], second);

Use this:

var memoryStream = new MemoryStream();
stream.CopyTo(memoryStream);

This will convert Stream to MemoryStream.

Little bit late to the party but had some problems with getting something useful out from a ReadableStream produced from a Odata $batch request using the Sharepoint Framework.

Had similar issues as OP, but the solution in my case was to use a different conversion method than .json(). In my case .text() worked like a charm. Some fiddling was however necessary to get some useful JSON from the textfile.

I think you are using it in wrong way. Here is an excerpt from the changelog:

New: @Url parameter annotation allows passing a complete URL for an endpoint.

So your interface should be like this:

public interface APIService {
    @GET
    Call<Users> getUsers(@Url String url);
}

Implement __str__() or __repr__() in the class's metaclass.

class MC(type):
  def __repr__(self):
    return 'Wahaha!'

class C(object):
  __metaclass__ = MC

print C

Use __str__ if you mean a readable stringification, use __repr__ for unambiguous representations.

I would recommend you to use worksheet's index instead of using worksheet's name, in this way you can also loop through sheets "dynamically"

for i=1 to thisworkbook.sheets.count
 sheets(i).activate
'You can add more code 
with activesheet
 'Code...
end with
next i

It will also, improve performance.

One object may contain another as a part of its attribute.

1. document contains sentences which contain words.
2. Computer system has a hard disk, ram, processor etc.

So containment need not be physical. e.g., computer system has a warranty.

Please note: The first part of this answer is or version 1.x of pendulum. See below for a version 2.x answer.

I hope I'm not too late!

The pendulum library excels at this and other date-time calculations.

>>> import pendulum
>>> some_time_zones = ['Europe/Paris', 'Europe/Moscow', 'America/Toronto', 'UTC', 'Canada/Pacific', 'Asia/Macao']
>>> heres_a_time = '1996-03-25 12:03 -0400'
>>> pendulum_time = pendulum.datetime.strptime(heres_a_time, '%Y-%m-%d %H:%M %z')
>>> for tz in some_time_zones:
...     tz, pendulum_time.astimezone(tz)
...     
('Europe/Paris', <Pendulum [1996-03-25T17:03:00+01:00]>)
('Europe/Moscow', <Pendulum [1996-03-25T19:03:00+03:00]>)
('America/Toronto', <Pendulum [1996-03-25T11:03:00-05:00]>)
('UTC', <Pendulum [1996-03-25T16:03:00+00:00]>)
('Canada/Pacific', <Pendulum [1996-03-25T08:03:00-08:00]>)
('Asia/Macao', <Pendulum [1996-03-26T00:03:00+08:00]>)

Answer lists the names of the time zones that may be used with pendulum. (They're the same as for pytz.)

For version 2:

• some_time_zones is a list of the names of the time zones that might be used in a program
• heres_a_time is a sample time, complete with a time zone in the form '-0400'
• I begin by converting the time to a pendulum time for subsequent processing
• now I can show what this time is in each of the time zones in show_time_zones

...

>>> import pendulum
>>> some_time_zones = ['Europe/Paris', 'Europe/Moscow', 'America/Toronto', 'UTC', 'Canada/Pacific', 'Asia/Macao']
>>> heres_a_time = '1996-03-25 12:03 -0400'
>>> pendulum_time = pendulum.from_format('1996-03-25 12:03 -0400', 'YYYY-MM-DD hh:mm ZZ')
>>> for tz in some_time_zones:
...     tz, pendulum_time.in_tz(tz)
...     
('Europe/Paris', DateTime(1996, 3, 25, 17, 3, 0, tzinfo=Timezone('Europe/Paris')))
('Europe/Moscow', DateTime(1996, 3, 25, 19, 3, 0, tzinfo=Timezone('Europe/Moscow')))
('America/Toronto', DateTime(1996, 3, 25, 11, 3, 0, tzinfo=Timezone('America/Toronto')))
('UTC', DateTime(1996, 3, 25, 16, 3, 0, tzinfo=Timezone('UTC')))
('Canada/Pacific', DateTime(1996, 3, 25, 8, 3, 0, tzinfo=Timezone('Canada/Pacific')))
('Asia/Macao', DateTime(1996, 3, 26, 0, 3, 0, tzinfo=Timezone('Asia/Macao')))

For Swift 3, the below code scales the image keeping the aspect ratio. You can read more about the ImageContext in Apple's documentation:

extension UIImage {
    class func resizeImage(image: UIImage, newHeight: CGFloat) -> UIImage {
        let scale = newHeight / image.size.height
        let newWidth = image.size.width * scale
        UIGraphicsBeginImageContext(CGSize(width: newWidth, height: newHeight))
        image.draw(in: CGRect(x: 0, y: 0, width: newWidth, height: newHeight))
        let newImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        return newImage!
    }
}

To use it, call resizeImage() method:

UIImage.resizeImage(image: yourImageName, newHeight: yourImageNewHeight)

Both @Autowired (or @Inject) and @Resource work equally well. But there is a conceptual difference or a difference in the meaning

• @Resource means get me a known resource by name. The name is extracted from the name of the annotated setter or field, or it is taken from the name-Parameter.
• @Inject or @Autowired try to wire in a suitable other component by type.

So, basically these are two quite distinct concepts. Unfortunately the Spring-Implementation of @Resource has a built-in fallback, which kicks in when resolution by-name fails. In this case, it falls back to the @Autowired-kind resolution by-type. While this fallback is convenient, IMHO it causes a lot of confusion, because people are unaware of the conceptual difference and tend to use @Resource for type-based autowiring.

'raw string' means it is stored as it appears. For example, '\' is just a backslash instead of an escaping.

What you're looking for is the function strlcpy() which does terminate always the string with 0 and initializes the buffer. It also is able to detect overflows. Only problem, it's not (really) portable and is present only on some systems (BSD, Solaris). The problem with this function is that it opens another can of worms as can be seen by the discussions on http://en.wikipedia.org/wiki/Strlcpy

My personal opinion is that it is vastly more useful than strncpy() and strcpy(). It has better performance and is a good companion to snprintf(). For platforms which do not have it, it is relatively easy to implement. (for the developement phase of a application I substitute these two function (snprintf() and strlcpy()) with a trapping version which aborts brutally the program on buffer overflows or truncations. This allows to catch quickly the worst offenders. Especially if you work on a codebase from someone else.

EDIT: strlcpy() can be implemented easily:

size_t strlcpy(char *dst, const char *src, size_t dstsize)
{
  size_t len = strlen(src);
  if(dstsize) {
    size_t bl = (len < dstsize-1 ? len : dstsize-1);
    ((char*)memcpy(dst, src, bl))[bl] = 0;
  }
  return len;
}

s = s.Substring(0, Math.Max(0, s.Length - 2))

to include the case where the length is less than 2

The ListAvailable option doesn't work for me. Instead this does:

if (-not (Get-Module -Name "<moduleNameHere>")) {
    # module is not loaded
}

Or, to be more succinct:

if (!(Get-Module "<moduleNameHere>")) {
    # module is not loaded
}

NUMBER (precision, scale) means precision number of total digits, of which scale digits are right of the decimal point.

NUMBER(2,2) in other words means a number with 2 digits, both of which are decimals. You may mean to use NUMBER(4,2) to get 4 digits, of which 2 are decimals. Currently you can just insert values with a zero integer part.

I had a similar problem, made all the more infuriating by simply being very SLOW to update. I couldn't get my changes to take effect while working on the site to save my life (trying all manner of clearing my browser cache and cookies), but if I came back to the site later in the day or opened another browser, there they were.

I also solved the problem by disabling the Supercacher software at my host's cpanel (Siteground). You can also use the "flush" button for individual directories to test if that's it before disabling.

I found a way to cover the shadow with ":after", here is my code:

#div:after {
    content:"";
    position:absolute;
    width:5px;
    background:#fff;
    height:38px;
    top:1px;
    right:-5px;
}

As this is the first result on google and there's no C++20 answer yet, here's how to use std::chrono to do this:

#include <chrono>

//...

using namespace std::chrono;
int64_t timestamp = duration_cast<milliseconds>(system_clock::now().time_since_epoch()).count();

In versions of C++ before 20, system_clock's epoch being Unix epoch is a de-facto convention, but it's not standardized. If you're not on C++20, use at your own risk.

I assume that you've run yum upgrade. That will in general update you to the newest minor release.

Your main resources for determining the version are /etc/redhat_release and lsb_release -a

From Asp.net core 2.2 to above you can code as below:

Step 1. Create an AppSettings class file.

This file contains some methods to help get value by key from the appsettings.json file. Look like as code below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace ReadConfig.Bsl
{
  public class AppSettings
  {
      private static AppSettings _instance;
      private static readonly object ObjLocked = new object();
      private IConfiguration _configuration;

      protected AppSettings()
      {
      }

      public void SetConfiguration(IConfiguration configuration)
      {
          _configuration = configuration;
      }

      public static AppSettings Instance
      {
          get
          {
              if (null == _instance)
              {
                  lock (ObjLocked)
                  {
                      if (null == _instance)
                          _instance = new AppSettings();
                  }
              }
              return _instance;
          }
      }

      public string GetConnection(string key, string defaultValue = "")
      {
          try
          {
              return _configuration.GetConnectionString(key);
          }
          catch
          {
              return defaultValue;
          }
      }

      public T Get<T>(string key = null)
      {
          if (string.IsNullOrWhiteSpace(key))
              return _configuration.Get<T>();
          else
              return _configuration.GetSection(key).Get<T>();
      }

      public T Get<T>(string key, T defaultValue)
      {
          if (_configuration.GetSection(key) == null)
              return defaultValue;

          if (string.IsNullOrWhiteSpace(key))
              return _configuration.Get<T>();
          else
              return _configuration.GetSection(key).Get<T>();
      }

      public static T GetObject<T>(string key = null)
      {
          if (string.IsNullOrWhiteSpace(key))
              return Instance._configuration.Get<T>();
          else
          {
              var section = Instance._configuration.GetSection(key);
              return section.Get<T>();
          }
      }

      public static T GetObject<T>(string key, T defaultValue)
      {
          if (Instance._configuration.GetSection(key) == null)
              return defaultValue;

          if (string.IsNullOrWhiteSpace(key))
              return Instance._configuration.Get<T>();
          else
              return Instance._configuration.GetSection(key).Get<T>();
      }
  }
}

Step 2. Initial configuration for AppSettings object

We need to declare and load appsettings.json file when the application starts, and load configuration information for AppSettings object. We will do this work in the constructor of the Startup.cs file. Please notice line AppSettings.Instance.SetConfiguration(Configuration);

public Startup(IHostingEnvironment evm)
{
    var builder = new ConfigurationBuilder()
      .SetBasePath(evm.ContentRootPath)
      .AddJsonFile("appsettings.json", true, true)
      .AddJsonFile($"appsettings.{evm.EnvironmentName}.json", true)
      .AddEnvironmentVariables();
    Configuration = builder.Build(); // load all file config to Configuration property 
    AppSettings.Instance.SetConfiguration(Configuration);       
}

Okay, now I have an appsettings.json file with some keys as below:

{
  "Logging": {
    "LogLevel": {
      "Default": "Information",
      "Microsoft": "Warning",
      "Microsoft.Hosting.Lifetime": "Information"
    }
  },
  "AllowedHosts": "*",
  "ConnectionStrings": {
    "ConnectionString": "Data Source=localhost;Initial Catalog=ReadConfig;Persist Security Info=True;User ID=sa;Password=12345;"
  },
  "MailConfig": {
    "Servers": {
      "MailGun": {
        "Pass": "65-1B-C9-B9-27-00",
        "Port": "587",
        "Host": "smtp.gmail.com"
      }
    },
    "Sender": {
      "Email": "[email protected]",
      "Pass": "123456"
    }
  }
}

Step 3. Read config value from an action

I make demo an action in Home controller as below :

public class HomeController : Controller
{
    public IActionResult Index()
    {
        var connectionString = AppSettings.Instance.GetConnection("ConnectionString");
        var emailSender = AppSettings.Instance.Get<string>("MailConfig:Sender:Email");
        var emailHost = AppSettings.Instance.Get<string>("MailConfig:Servers:MailGun:Host");

        string returnText = " 1. Connection String \n";
        returnText += "  " +connectionString;
        returnText += "\n 2. Email info";
        returnText += "\n Sender : " + emailSender;
        returnText += "\n Host : " + emailHost;

        return Content(returnText);
    }
}

And below is the result:

The startActivityForResult pattern is much better suited for what you're trying to achieve : http://developer.android.com/reference/android/app/Activity.html#StartingActivities

Try below code

public class MainActivity extends Activity {  

    Button button1;  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
        textView1=(TextView)findViewById(R.id.textView1);  
        button1=(Button)findViewById(R.id.button1);  
        button1.setOnClickListener(new OnClickListener() {  
            @Override  
            public void onClick(View arg0) {  
                Intent intent=new Intent(MainActivity.this,SecondActivity.class);  
                startActivityForResult(intent, 2);// Activity is started with requestCode 2  
            }  
        });  
    }  
 // Call Back method  to get the Message form other Activity  
    @Override  
       protected void onActivityResult(int requestCode, int resultCode, Intent data)  
       {  
                 super.onActivityResult(requestCode, resultCode, data);  
                  // check if the request code is same as what is passed  here it is 2  
                   if(requestCode==2)  
                         {  
                          //do the things u wanted 
                         }  
     }  

} 

SecondActivity.class

public class SecondActivity extends Activity {  

    Button button1;  
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_second);  

            button1=(Button)findViewById(R.id.button1);  
            button1.setOnClickListener(new OnClickListener() {  
                @Override  
                public void onClick(View arg0) {  
                    String message="hello ";  
                    Intent intent=new Intent();  
                    intent.putExtra("MESSAGE",message);  
                    setResult(2,intent);  
                    finish();//finishing activity  
                }  
            });  
    }  

}  

Let me know if it helped...

EDIT: The other two answers make a good point. I'm assuming that you want to order them into some other structure, or in order to print them out.

"Best" can mean a number of different things. Do you mean "easiest," "fastest," "most efficient," "least code," "most readable?"

The most obvious approach is to loop through twice. On the first pass, order the values:

if(current_value > examined_value)
{
    current_value = examined_value
    (and then swap them, however you like)
}

Then on the second pass, alphabetize the words, but only if their values match.

if(current_value == examined_value)
{
    (alphabetize the two)
}

Strictly speaking, this is a "bubble sort" which is slow because every time you make a swap, you have to start over. One "pass" is finished when you get through the whole list without making any swaps.

There are other sorting algorithms, but the principle would be the same: order by value, then alphabetize.

rem This is the command line version
cscript "C:\Users\guest\Desktop\123\MyScript.vbs"

OR

rem This is the windowed version
wscript "C:\Users\guest\Desktop\123\MyScript.vbs"

You can also add the option //e:vbscript to make sure the scripting engine will recognize your script as a vbscript.

Windows/DOS batch files doesn't require escaping \ like *nix.

You can still use "C:\Users\guest\Desktop\123\MyScript.vbs", but this requires the user has *.vbs associated to wscript.

http://docs.jquery.com/Events/jQuery.Event

Try with event.target

Contains the DOM element that issued the event. This can be the element that registered for the event or a child of it.

In my case the key was:

AllowOverride All

in vhost definition. I hope it helps someone.

I Found some code for wordpress:

 <script type="text/javascript">

    function insert_pinterest($content) {
        global $post;
        $posturl = urlencode(get_permalink()); //Get the post URL
        $pinspan = '<span class="pinterest-button">';
     $pinurl = '';
     $pinend = '</span>';
        $pattern = '//i';
        $replacement = $pinspan.$pinurl.'$2.$3'.$pindescription.$pinfinish.''.$pinend;
        $content = preg_replace( $pattern, $replacement, $content );
        //Fix the link problem
        $newpattern = '/<span class="pinterest-button"><\/a><\/span><\/a>/i';
     $replacement = '';
     $content = preg_replace( $newpattern, $replacement, $content );
     return $content;
    }
    add_filter( 'the_content', 'insert_pinterest' );

    </script>

Then you put the following in your PHP:

<?php $pinterestimage = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'full' ); ?>
<a href="http://pinterest.com/pin/create/button/?url=<?php echo urlencode(get_permalink($post->ID)); ?>&media=<?php echo $pinterestimage[0]; ?>&description=<?php the_title(); ?>">Pin It</a>

From commons-lang3

org.apache.commons.lang3.text.WordUtils.capitalizeFully(String str)

<div> is a block-level element and <span> is an inline element.

If you wanted to do something with some inline text, <span> is the way to go since it will not introduce line breaks that a <div> would.

As noted by others, there are some semantics implied with each of these, most significantly the fact that a <div> implies a logical division in the document, akin to maybe a section of a document or something, a la:

<div id="Chapter1">
   <p>Lorem ipsum dolor sit amet, <span id="SomeSpecialText1">consectetuer adipiscing</span> elit. Duis congue vehicula purus.</p>
   <p>Nam <span id="SomeSpecialText2">eget magna nec</span> sapien fringilla euismod. Donec hendrerit.</p> 
</div>

In the child

 <input
            type="number"
            class="form-control"
            id="phoneNumber"
            placeholder
            v-model="contact_number"
            v-on:input="(event) => this.$emit('phoneNumber', event.target.value)"
    />

data(){
    return {
      contact_number : this.contact_number_props
    }
  },
  props : ['contact_number_props']

In parent

<contact-component v-on:phoneNumber="eventPhoneNumber" :contact_number_props="contact_number"></contact-component>


 methods : {
     eventPhoneNumber (value) {
      this.contact_number = value
    }

We can make use of LocalDate and ChronoUnit java library, Below code is working fine. Date should be in format yyyy-MM-dd.

import java.time.LocalDate;
import java.time.temporal.ChronoUnit;
import java.util.*;
class Solution {
    public int daysBetweenDates(String date1, String date2) {
        LocalDate dt1 = LocalDate.parse(date1);
        LocalDate dt2= LocalDate.parse(date2);

        long diffDays = ChronoUnit.DAYS.between(dt1, dt2);

        return Math.abs((int)diffDays);
    }
}

What about just using virtual desktops? You can spread your windows around among multiple workspaces. Something like Virtual Dimension should give you most of that functionality. I use virtual desktops all the time on Linux, and it's the next best thing to multiple monitors.

It seems if you do not use any encType (default is application/x-www-form-urlencoded) then you do get text input fields but you wouldn't get file.

If you have a form where you want to post text input and file then use multipart/form-data encoding type and in addition to that use multer middleware. Multer will parse the request object and prepare req.file for you and all other inputs fields will be available through req.body.
