It's deprecated but it still works so you could just use it. But if you want to be completly correct, just for the completeness of it... You'd do something like following:

int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    setBackgroundDrawable();
} else {
    setBackground();
}

For this to work you need to set buildTarget api 16 and min build to 7 or something similar.

Edited solution that will make your SplashScreen look great on all APIs including API21 to API23

If you are only targeting APIs24+ you can simply scale down your vector drawable directly in its xml file like so:

<vector xmlns:android="http://schemas.android.com/apk/res/android" xmlns:aapt="http://schemas.android.com/aapt"
android:viewportWidth="640"
android:viewportHeight="640"
android:width="240dp"
android:height="240dp">
<path
    android:pathData="M320.96 55.9L477.14 345L161.67 345L320.96 55.9Z"
    android:strokeColor="#292929"
    android:strokeWidth="24" />
</vector>

in the code above I am rescaling a drawable I drew on a 640x640 canvas to be 240x240. then i just put it in my splash screen drawable like so and it works great:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" android:opacity="opaque"
android:paddingBottom="20dp" android:paddingRight="20dp" android:paddingLeft="20dp" android:paddingTop="20dp">

<!-- The background color, preferably the same as your normal theme -->
<item>
    <shape>
        <size android:height="120dp" android:width="120dp"/>
        <solid android:color="@android:color/white"/>
    </shape>
</item>

<!-- Your product logo - 144dp color version of your app icon -->
<item
    android:drawable="@drawable/logo_vect"
    android:gravity="center">

</item>
</layer-list>

my code is actually only drawing the triangle in the picture at the bottom but here you see what you can achieve with this. Resolution is finally great as opposed to the pixelated edges I was getting when using bitmap. so use a vector drawable by all means (there is a site called vectr that I used to create mine without the hasle of downloading specialized software).

EDIT in order to make it work also on API21-22-23

While the solution above works for devices runing API24+ I got really disappointed after installing my app a device running API22. I noticed that the splashscreen was again trying to fill the entire view and looking like shit. After tearing my eyebrows out for half a day I finally brute-forced a solution by sheer willpower.

you need to create a second file named exactly like the splashscreen xml (lets say splash_screen.xml) and place it into 2 folders called drawable-v22 and drawable-v21 that you will create in the res/ folder (in order to see them you have to change your project view from Android to Project). This serves to tell your phone to redirect to files placed in those folders whenever the relevant device runs an API corresponding to the -vXX suffix in the drawable folder, see this link. place the following code in the Layer-list of the splash_screen.xml file that you create in these folders:

<item>
<shape>
    <size android:height="120dp" android:width="120dp"/>
    <solid android:color="@android:color/white"/>
</shape>
</item>

<!-- Your product logo - 144dp color version of your app icon -->
<item android:gravity="center">
    <bitmap android:gravity="center"
        android:src="logo_vect"/>

</item>

For some reason for these APIs you have to wrap your drawable in a bitmap in order to make it work and jet the final result looks the same. The issue is that you have to use the aproach with the aditional drawable folders as the second version of the splash_screen.xml file will lead to your splash screen not being shown at all on devices running APIs higher than 23. You might also have to place the first version of the splash_screen.xml into drawable-v24 as android defaults to the closest drawable-vXX folder it can find for resources. hope this helps

Use assets folder.

sample code:

InputStream is = null;
try {
    is = this.getResources().getAssets().open("test/sample.png");
} catch (IOException e) {
    ;
}

image = BitmapFactory.decodeStream(is);

mbaird's answer works fine. Just be aware that there seems to be a bug in Android (2.1 at least), that if you set any individual corner's radius to 0, it forces all the corners to 0 (at least that's the case with "dp" units; I didn't try it with any other units).

I needed a shape where the top corners were rounded and the bottom corners were square. I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0: 0.1dp. This still renders as square corners, but it doesn't force the other corners to be 0 radius.

I tried your code and got a top rounded corner button. I gave the colors as @ffffff and stroke I gave #C0C0C0.

try

1. Giving android : bottomLeftRadius="0.1dp" instead of 0. if its not working
2. Check in what drawable and the emulator's resolution. I created a drawable folder under res and using it. (hdpi, mdpi ldpi) the folder you have this XML. this is my output.

Get Drawable from vector resource irrespective of, whether its vector or not:

AppCompatResources.getDrawable(context, R.drawable.icon);

Note:
ContextCompat.getDrawable(context, R.drawable.icon); will produce android.content.res.Resources$NotFoundException for vector resource.

In drawable I use this xml code to define the border and background:

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
  <stroke android:width="4dp" android:color="#D8FDFB" /> 
  <padding android:left="7dp" android:top="7dp" 
    android:right="7dp" android:bottom="7dp" /> 
  <corners android:radius="4dp" /> 
  <solid android:color="#f0600000"/> 
</shape> 

Use butterknife to bind the drawable resource to a variable by adding this to the top of your class (before any methods).

@Bind(R.id.some_layout)
RelativeLayout layout;
@BindDrawable(R.drawable.some_drawable)
Drawable background;

then inside one of your methods add

layout.setBackground(background);

That's all you need

Simplify the name of your file, seems to be that any special characters in the file name makes it hiccup. for example chaange "my-main-header.png" to "header1.png" not sure why, but it works

As of API 21, you could also use:

   ResourcesCompat.getDrawable(getResources(), R.drawable.name, null);

Instead of ContextCompat.getDrawable(context, android.R.drawable.ic_dialog_email)

If you are planning to get the image from its path, it's better to use Assets instead of trying to figure out the path of the drawable folder.

    InputStream stream = getAssets().open("image.png");
    Drawable d = Drawable.createFromStream(stream, null);

Better you copy and move them to your own resources. Some resources might not be available on previous Android versions. Here is a link with all drawables available on each Android version thanks to @fiXedd

As far as I know there is not an easy way to do this since Javascript/JQuery does not have access to the local filesystem. There are some new features in html 5 that allows you to check certain meta data such as file size but I'm not sure if you can actually get the image dimensions.

Here is an article I found regarding the html 5 features, and a work around for IE that involves using an ActiveX control. http://jquerybyexample.blogspot.com/2012/03/how-to-check-file-size-before-uploading.html

I ran into this problem today and this was the trick I did, which worked for me:

   EntityManagerFactory emf = Persistence.createEntityManagerFactory("DAOMANAGER");
   EntityManagerem = emf.createEntityManager();

   org.hibernate.Session session = ((EntityManagerImpl) em).getSession();
   java.sql.Connection connectionObj = session.connection();

Though not the best way but does the job.

A possible way to achieve this is the following.

if (!Object.prototype.merge){
    Object.prototype.merge = function(obj){
        var self = this;
        Object.keys(obj).forEach(function(key){
            self[key] = obj[key]
        });
    }
};

I don't know if it's better then the other answers. In this method you add the merge function to Objects prototype. This way you can call obj1.merge(obj2);

Note : you should validate your argument to see if its an object and 'throw' a proper Error. If not Object.keys will 'throw' an 'Error'

exit code 139 (people say this means memory fragmentation)

No, it means that your program died with signal 11 (SIGSEGV on Linux and most other UNIXes), also known as segmentation fault.

Could anybody tell me why the run fails but debug doesn't?

Your program exhibits undefined behavior, and can do anything (that includes appearing to work correctly sometimes).

Your first step should be running this program under Valgrind, and fixing all errors it reports.

If after doing the above, the program still crashes, then you should let it dump core (ulimit -c unlimited; ./a.out) and then analyze that core dump with GDB: gdb ./a.out core; then use where command.

I think you have to write some extra code. For example:

if 'MICHAEL89' in map(lambda name: name.upper(), USERNAMES):
   ...

In this case we are forming a new list with all entries in USERNAMES converted to upper case and then comparing against this new list.

Update

As @viraptor says, it is even better to use a generator instead of map. See @Nathon's answer.

To retreive the value of all selected item in à listbox you can cast selected item in DataRowView and then select column where your data is:

foreach(object element in listbox.SelectedItems) {
    DataRowView row = (DataRowView)element;
    MessageBox.Show(row[0]);
}

To temporarily disable the draggable behavior use:

$('#item-id').draggable( "disable" )

To remove the draggable behavior permanently use:

$('#item-id').draggable( "destroy" )

Sprintf is what you are looking for.

Example

fmt.Sprintf("foo: %s", bar)

You can also see it in use in the Errors example as part of "A Tour of Go."

return fmt.Sprintf("at %v, %s", e.When, e.What)

I think a good question would be: how does HTTP work? Working with GET and POST data among other HTTP communications is inherent in PHP development. Understanding how HTTP works in a broader context and how PHP implements this goes a long way.

Here are two popular Github libraries for node js authentication:

https://github.com/jaredhanson/passport ( suggestible )

https://nodejsmodules.org/pkg/everyauth

install exceljs and use the following code,

var Excel = require('exceljs');

var wb = new Excel.Workbook();
var path = require('path');
var filePath = path.resolve(__dirname,'sample.xlsx');

wb.xlsx.readFile(filePath).then(function(){

    var sh = wb.getWorksheet("Sheet1");

    sh.getRow(1).getCell(2).value = 32;
    wb.xlsx.writeFile("sample2.xlsx");
    console.log("Row-3 | Cell-2 - "+sh.getRow(3).getCell(2).value);

    console.log(sh.rowCount);
    //Get all the rows data [1st and 2nd column]
    for (i = 1; i <= sh.rowCount; i++) {
        console.log(sh.getRow(i).getCell(1).value);
        console.log(sh.getRow(i).getCell(2).value);
    }
});

Another thing to keep in mind is there are two different CASEs with MySQL: one like what @cdhowie and others describe here (and documented here: http://dev.mysql.com/doc/refman/5.7/en/control-flow-functions.html#operator_case) and something which is called a CASE, but has completely different syntax and completely different function, documented here: https://dev.mysql.com/doc/refman/5.0/en/case.html

Invariably, I first use one when I want the other.

Instead of using the new 'track by' feature you can simply do this with an array if you want the values to be the same as the text:

<select ng-options="v as v for (k,v) in Array/Obj"></select>

Note the difference between the standard syntax, which will make the values the keys of the Object/Array, and therefore 0,1,2 etc. for an array:

<select ng-options"k as v for (k,v) in Array/Obj"></select>

k as v becomes v as v.

I discovered this just based on common sense looking at the syntax. (k,v) is the actual statement that splits the array/object into key value pairs.

In the 'k as v' statement, k will be the value, and v will be the text option displayed to the user. I think 'track by' is messy and overkill.

easily set

position:absolute;
bottom:0;
width:100%;

Either you're not including jquery toolkit/lib, as some have suggested, or there is a conflict of sorts. To test: include jQuery and test like this:

console.log($);
console.log($ === jQuery);

If $ is not undefined, and $ === jQuery logs false, you definitely have a conflict on your hands. Replacing your $ with jQuery solves that, but that can be quite tedious (all that extra typing...). Generally I start my scripts with $jq = _$ = jQuery; to at least have a shorter reference to the jQuery object.
Of course, before you do that, check to see if you're not accidentally overriding variables that have been set beforehand: console.log($jq, _jQ, _$); whichever is not undefined should be left alone, of course

I use:

• express and
• morgan
  
  

Install Node.js. and npm. npm is installed with Node.js

Placed inside the root project directory

$ cd <your_angularjs_project>

The next command creates package.json

$ npm init

Install express ==> Fast, unopinionated, minimalist for node:

$ npm install express --save

Install morgan ==> HTTP request logger middleware for node.js

$ npm install morgan --save

create file server.js

add the following code in server.js file

// Required Modules
var express    = require("express");
var morgan     = require("morgan");
var app        = express();

var port = process.env.PORT || 3002;

app.use(morgan("dev"));
app.use(express.static("./"));

app.get("/", function(req, res) {
    res.sendFile("./index.html"); //index.html file of your angularjs application
});

// Start Server
app.listen(port, function () {
    console.log( "Express server listening on port " + port);
});

Finally run your AngularJS project in localhost server:

$ node server.js

Note that the search query is now case sensitive.

When using

SELECT * FROM table WHERE `first_name` LIKE '%$search_term%'

It will match both "Larry" and "larry". With this concat_ws, it will suddenly become case sensitive!

This can be fixed by using the following query:

SELECT * FROM table WHERE UPPER(CONCAT_WS(' ', `first_name`, `last_name`) LIKE UPPER('%$search_term%')

Edit: Note that this only works on non-binary elements. See also mynameispaulie's answer.

The fact that the sort values in the OP are integers isn't relevant to the question per se. In other words, the accepted answer would work if the sort value was text. I bring this up to also point out that the sort can be modified during the sort (for example, to account for upper and lower case).

>>> sorted([(121, 'abc'), (231, 'def'), (148, 'ABC'), (221, 'DEF')], key=lambda x: x[1])
[(148, 'ABC'), (221, 'DEF'), (121, 'abc'), (231, 'def')]
>>> sorted([(121, 'abc'), (231, 'def'), (148, 'ABC'), (221, 'DEF')], key=lambda x: str.lower(x[1]))
[(121, 'abc'), (148, 'ABC'), (231, 'def'), (221, 'DEF')]

The Django documentation for database queries includes a section on copying model instances. Assuming your primary keys are autogenerated, you get the object you want to copy, set the primary key to None, and save the object again:

blog = Blog(name='My blog', tagline='Blogging is easy')
blog.save() # blog.pk == 1

blog.pk = None
blog.save() # blog.pk == 2

In this snippet, the first save() creates the original object, and the second save() creates the copy.

If you keep reading the documentation, there are also examples on how to handle two more complex cases: (1) copying an object which is an instance of a model subclass, and (2) also copying related objects, including objects in many-to-many relations.

Note on miah's answer: Setting the pk to None is mentioned in miah's answer, although it's not presented front and center. So my answer mainly serves to emphasize that method as the Django-recommended way to do it.

Historical note: This wasn't explained in the Django docs until version 1.4. It has been possible since before 1.4, though.

Possible future functionality: The aforementioned docs change was made in this ticket. On the ticket's comment thread, there was also some discussion on adding a built-in copy function for model classes, but as far as I know they decided not to tackle that problem yet. So this "manual" way of copying will probably have to do for now.

I'm writing this to make sure I understand it properly.

Move semantics were created to avoid the unnecessary copying of large objects. Bjarne Stroustrup in his book "The C++ Programming Language" uses two examples where unnecessary copying occurs by default: one, the swapping of two large objects, and two, the returning of a large object from a method.

Swapping two large objects usually involves copying the first object to a temporary object, copying the second object to the first object, and copying the temporary object to the second object. For a built-in type, this is very fast, but for large objects these three copies could take a large amount of time. A "move assignment" allows the programmer to override the default copy behavior and instead swap references to the objects, which means that there is no copying at all and the swap operation is much faster. The move assignment can be invoked by calling the std::move() method.

Returning an object from a method by default involves making a copy of the local object and its associated data in a location which is accessible to the caller (because the local object is not accessible to the caller and disappears when the method finishes). When a built-in type is being returned, this operation is very fast, but if a large object is being returned, this could take a long time. The move constructor allows the programmer to override this default behavior and instead "reuse" the heap data associated with the local object by pointing the object being returned to the caller to heap data associated with the local object. Thus no copying is required.

In languages which do not allow the creation of local objects (that is, objects on the stack) these types of problems do not occur as all objects are allocated on the heap and are always accessed by reference.

It's now possible to add a forced line break
with two blank spaces at the end of the line:

line1??
line2

will be formatted as:

line1
line2

This should work

<a href="javascript:window.open('document.aspx','mywindowtitle','width=500,height=150')">open window</a>

This is what I use to deep watch an object. My requirement was watching the child fields of the object.

new Vue({
    el: "#myElement",
    data:{
        entity: {
            properties: []
        }
    },
    watch:{
        'entity.properties': {
            handler: function (after, before) {
                // Changes detected.    
            },
            deep: true
        }
    }
});

First, let's make some test data:

create table client (client_id integer not null primary key auto_increment,
                     name varchar(64));
create table portfolio (portfolio_id integer not null primary key auto_increment,
                        client_id integer references client.id,
                        cash decimal(10,2),
                        stocks decimal(10,2));
insert into client (name) values ('John Doe'), ('Jane Doe');
insert into portfolio (client_id, cash, stocks) values (1, 11.11, 22.22),
                                                       (1, 10.11, 23.22),
                                                       (2, 30.30, 40.40),
                                                       (2, 40.40, 50.50);

If you didn't need the portfolio ID, it would be easy:

select client_id, name, max(cash + stocks)
from client join portfolio using (client_id)
group by client_id

+-----------+----------+--------------------+
| client_id | name     | max(cash + stocks) |
+-----------+----------+--------------------+
|         1 | John Doe |              33.33 | 
|         2 | Jane Doe |              90.90 | 
+-----------+----------+--------------------+

Since you need the portfolio ID, things get more complicated. Let's do it in steps. First, we'll write a subquery that returns the maximal portfolio value for each client:

select client_id, max(cash + stocks) as maxtotal
from portfolio
group by client_id

+-----------+----------+
| client_id | maxtotal |
+-----------+----------+
|         1 |    33.33 | 
|         2 |    90.90 | 
+-----------+----------+

Then we'll query the portfolio table, but use a join to the previous subquery in order to keep only those portfolios the total value of which is the maximal for the client:

 select portfolio_id, cash + stocks from portfolio 
 join (select client_id, max(cash + stocks) as maxtotal 
       from portfolio
       group by client_id) as maxima
 using (client_id)
 where cash + stocks = maxtotal

+--------------+---------------+
| portfolio_id | cash + stocks |
+--------------+---------------+
|            5 |         33.33 | 
|            6 |         33.33 | 
|            8 |         90.90 | 
+--------------+---------------+

Finally, we can join to the client table (as you did) in order to include the name of each client:

select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
      from portfolio 
      group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal

+-----------+----------+--------------+---------------+
| client_id | name     | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
|         1 | John Doe |            5 |         33.33 | 
|         1 | John Doe |            6 |         33.33 | 
|         2 | Jane Doe |            8 |         90.90 | 
+-----------+----------+--------------+---------------+

Note that this returns two rows for John Doe because he has two portfolios with the exact same total value. To avoid this and pick an arbitrary top portfolio, tag on a GROUP BY clause:

select client_id, name, portfolio_id, cash + stocks
from client
join portfolio using (client_id)
join (select client_id, max(cash + stocks) as maxtotal
      from portfolio 
      group by client_id) as maxima
using (client_id)
where cash + stocks = maxtotal
group by client_id, cash + stocks

+-----------+----------+--------------+---------------+
| client_id | name     | portfolio_id | cash + stocks |
+-----------+----------+--------------+---------------+
|         1 | John Doe |            5 |         33.33 | 
|         2 | Jane Doe |            8 |         90.90 | 
+-----------+----------+--------------+---------------+

You can use:

$('#table').dataTable().fnClearTable();
$('#table').dataTable().fnAddData(myData2);

Update. And yes current documentation is not so good but if you are okay using older versions you can refer legacy documentation.

Oh lord, don't do it this way. HTC files are never a good idea for performance and clarity reasons, and you're using too many vendor-specific parameters for something that can easily be done cross-browser all the way back to IE6.

Apply a background image to your input field with the rounded corners and make the field's background colour transparent with border:none applied instead.

If the two byte arrays you mention is your entire key, the values are in the range 0-51, unique and the order within the a and b arrays is insignificant, my math tells me that there is only just about 26 million possible permutations and that you likely are trying to fill the map with values for all possible keys.

In this case, both filling and retrieving values from your data store would of course be much faster if you use an array instead of a HashMap and index it from 0 to 25989599.

Use @AutoConfigureMockMvc for test class.

I know this answer would look similar to most of the answers already here, but I noticed just about none of them uses a for-loop. This code works, and can be considered simple, in the sense it will work without any special functions, like a ToString() with parameters, and is not too long as well. Maybe some prefer for-loops instead of just while-loop, this may be suitable for them.

public static string ByteConvert (int num)
{
    int[] p = new int[8];
    string pa = "";
    for (int ii = 0; ii<= 7;ii = ii +1)
    {
        p[7-ii] = num%2;
        num = num/2;
    }
    for (int ii = 0;ii <= 7; ii = ii + 1)
    {
        pa += p[ii].ToString();
    }
    return pa;
}

In response to the final part of your question, which is still unanswered... When you write $('#video').duration, you're asking for the duration property of the jQuery collection object, which doesn't exist. The native DOM video element does have the duration. You can get that in a few ways.

Here's one:

// get the native element directly
document.getElementById('video').duration

Here's another:

// get it out of the jQuery object
$('#video').get(0).duration

And another:

// use the event object
v.bind('loadeddata', function(e) {
  console.log(e.target.duration);
});

I agree that cygwin/OpenSSH is the best choice, but its setup can be involved to say the least. Here is a document to get you started though: Installing OpenSSH

For windows, @shoaly parameters didn't completely work for me. I was getting this error:

NCAT DEBUG: Proxy returned status code 501.
Ncat: Proxy returned status code 501.
ssh_exchange_identification: Connection closed by remote host

I wanted to ssh to a REMOTESERVER and the SSH port had been closed in my network. I found two solutions but the second is better.

• To solve the problem using Ncat:

  1. I downloaded Tor Browser, run and wait to connect.
  2. I got Ncat from Nmap distribution and extracted ncat.exe into the current directory.

  3. SSH using Ncat as ProxyCommand in Git Bash with addition --proxy-type socks4 parameter:

     ssh -o "ProxyCommand=./ncat --proxy-type socks4 --proxy 127.0.0.1:9150 %h %p" USERNAME@REMOTESERVER
     

     Note that this implementation of Ncat does not support socks5.

• THE BETTER SOLUTION:

  1. Do the previous step 1.

  2. SSH using connect.c as ProxyCommand in Git Bash:

     ssh -o "ProxyCommand=connect -a none -S 127.0.0.1:9150 %h %p"
     

     Note that connect.c supports socks version 4/4a/5.

To use the proxy in git commands using ssh (for example while using GitHub) -- assuming you installed Git Bash in C:\Program Files\Git\ -- open ~/.ssh/config and add this entry:

host github.com
    user git
    hostname github.com
    port 22
    proxycommand "/c/Program Files/Git/mingw64/bin/connect.exe" -a none -S 127.0.0.1:9150 %h %p

To find a hostname in your local network by IP address you can use:

nmblookup -A <ip>

To find a hostname on the internet you could use the host program:

host <ip>

Or you can install nbtscan by running:

sudo apt-get install nbtscan

And use:

nbtscan <ip>

Update 2018-05-13

You can query a name server with nslookup. It works both ways!

nslookup <IP>
nslookup <hostname>

...I have a string "-9o0-9909" and I want to replace it with another string.

The code below will do that.

var str = '-9o0-9909';

str = 'new string';

Jokes aside, replacing text nodes is not trivial with JavaScript.

I've written a post about this: Replacing text with JavaScript.

I was experiencing this issue... in my case, I'd run out of storage on my dedicated server. Check that if everything else fails and consider increasing disk space or removing unwanted data or files.

I faced the same problem ago and instead, I used winston. As fellas above said, morgan is for automated logging of request/response. Winston can be configured pretty much same way as log4Net/log4J, has severity levels, different streams to which you can log etc.

For example:

npm install winston

Then, if you call the below code somewhere on you application initialization:

var winston = require('winston');

// setup default logger (no category)
winston.loggers.add('default', {
    console: {
        colorize: 'true',
        handleExceptions: true,
        json: false,
        level: 'silly',
        label: 'default',
    },
    file: {
        filename: 'some/path/where/the/log/file/reside/default.log',
        level: 'silly',
        json: false,
        handleExceptions: true,
    },
});

//
// setup logger for category `usersessions`
// you can define as many looggers as you like
//
winston.loggers.add('usersessions', {
    console: {
        level: 'silly',
        colorize: 'true',
        label: 'usersessions',
        json: false,
        handleExceptions: true,
    },
    file: {
        filename: 'some/path/where/the/log/file/reside/usersessions.log',
        level: 'silly',
        json: false,
        handleExceptions: true,
    },
});

note: before calling above code, winston.loggers is empty, i.e you dont have any loggers configured yet. Pretty much like Log4Net/J XmlConfigure methods - you need to first call them, to init your logging.

Then, later wherever in you application server side code you may do:

var winston = require('winston');
// log instances as defined in first snippet
var defaultLog = winston.loggers.get('default'); 
var userSessionsLog = winston.loggers.get('usersessions');

defaultLog.info('this goes to file default.log');
userSessionsLog.debug('this goes to file usersessions.log')

Hope that helps.

Some more convenient

"1,1200.00".gsub(/[^0-9]/,'') 

it makes "1 200 200" work properly aswell

You need to add reference (System.Web) Reference to System.Web

Even though the solution that was provided above is nice. I would also expect something like frame.column_names() to be a function in pandas, but since it is not, maybe it would be nice to use the following syntax. It somehow preserves the feeling that you are using pandas in a proper way by calling the "tolist" function: frame.columns.tolist()

frame.columns.tolist() 

You can use Application.wait now + timevalue("00:00:01") or Application.wait now + timeserial(0,0,1)

Try this code:

var id;
var vname;
function ajaxCall(){
for(var q = 1; q<=10; q++){
 $.ajax({                                            
     url: 'api.php',                        
     data: 'id1='+q+'',                                                         
     dataType: 'json',
     async:false,                    
     success: function(data)          
     {   
        id = data[0];              
        vname = data[1];
     },
    complete: function (data) {
      printWithAjax(); 
     }
    });

  }//end of the for statement
  }//end of ajax call function

The "complete" function executes only after the "success" of ajax. So try to call the printWithAjax() on "complete". This should work for you.

You can use moment.js for that, it will convert DateTime object into valid Javascript formated date:

   moment(DateOfBirth).format('DD-MMM-YYYY'); // put format as you want 

   Output: 28-Apr-1993

Hope it will help you :)

Here's the strsplit solution if s is a vector:

> s <- c("TGAS_1121", "MGAS_1432")
> s1 <- sapply(strsplit(s, split='_', fixed=TRUE), function(x) (x[2]))
> s1
[1] "1121" "1432"

Readonly is an attribute as defined in html, so treat it like one.

You need to have something like readonly="readonly" in the object you are working with if you want it not to be editable. And if you want it to be editable again you won't have something like readonly='' (this is not standard if I understood correctly). You really need to remove the attribute as a whole.

As such, while using jquery adding it and removing it is what makes sense.

Set something readonly:

$("#someId").attr('readonly', 'readonly');

Remove readonly:

$("#someId").removeAttr('readonly');

This was the only alternative that really worked for me. Hope it helps!

Translated from here:

Dimension getScaledDimension(Dimension imageSize, Dimension boundary) {

    double widthRatio = boundary.getWidth() / imageSize.getWidth();
    double heightRatio = boundary.getHeight() / imageSize.getHeight();
    double ratio = Math.min(widthRatio, heightRatio);

    return new Dimension((int) (imageSize.width  * ratio),
                         (int) (imageSize.height * ratio));
}

You can also use imgscalr to resize images while maintaining aspect ratio:

BufferedImage resizeMe = ImageIO.read(new File("orig.jpg"));
Dimension newMaxSize = new Dimension(255, 255);
BufferedImage resizedImg = Scalr.resize(resizeMe, Method.QUALITY,
                                        newMaxSize.width, newMaxSize.height);

`su -c "Your command right here" -s /bin/sh username`

The above command is correct, but on Red Hat if selinux is enforcing it will not allow cron to execute scripts as another user. example; execl: couldn't exec /bin/sh execl: Permission denied

I had to install setroubleshoot and setools and run the following to allow it:

yum install setroubleshoot setools
sealert -a /var/log/audit/audit.log
grep crond /var/log/audit/audit.log | audit2allow -M mypol
semodule -i mypol.p

My case, the server was encrypting with padding disabled. But the client was trying to decrypt with the padding enabled.

While using EVP_CIPHER*, by default the padding is enabled. To disable explicitly we need to do

EVP_CIPHER_CTX_set_padding(context, 0);

So non matching padding options can be one reason.

ArrayList<String> arrayList = new ArrayList<String>();
Object[] objectList = arrayList.toArray();
String[] stringArray =  Arrays.copyOf(objectList,objectList.length,String[].class);

Using copyOf, ArrayList to arrays might be done also.

You can achieve this using Angular modules:

navigator.clipboard.writeText('your text').then().catch(e => console.error(e));

The other answers to this question seem to hit it spot on. Now how would you figure this out for yourself without stack overflow? Check out IPython, an interactive Python shell that has tab auto-complete.

In [1]: import datetime
In [2]: now=datetime.datetime.now()
In [3]: now.

press tab a few times and you'll be prompted with the members of the "now" object:

now.__add__           now.__gt__            now.__radd__          now.__sub__           now.fromordinal       now.microsecond       now.second            now.toordinal         now.weekday
now.__class__         now.__hash__          now.__reduce__        now.astimezone        now.fromtimestamp     now.min               now.strftime          now.tzinfo            now.year
now.__delattr__       now.__init__          now.__reduce_ex__     now.combine           now.hour              now.minute            now.strptime          now.tzname
now.__doc__           now.__le__            now.__repr__          now.ctime             now.isocalendar       now.month             now.time              now.utcfromtimestamp
now.__eq__            now.__lt__            now.__rsub__          now.date              now.isoformat         now.now               now.timetuple         now.utcnow

now.__getattribute__  now.__new__           now.__str__           now.dst               now.max               now.resolution        now.today             now.utctimetuple

and you'll see that now.year is a member of the "now" object.

Try this code:

$(document).ready(function(){
    $('#YourControlID').click(function(){
        if() { //your condition
            $.messager.show({  
                title:'My Title',  
                msg:'The message content',  
                showType:'fade',  
                style:{  
                    right:'',  
                    bottom:''  
                }  
            });  
        }
    });
});

If you're looking to paginate results, use the integrated paginator, it works great!

$games = Game::paginate(30);
// $games->results = the 30 you asked for
// $games->links() = the links to next, previous, etc pages

Sure You can. I'd say that You should.

This article may be usefull:
http://www.learncpp.com/cpp-tutorial/812-static-member-functions/

all Values is always taken with .val().

see the code bellow:

var message = $('#message').val();

I will give you a better idea

for(decltype(things.size()) i = 0; i < things.size(); i++){
                   //...
}

decltype is

Inspects the declared type of an entity or the type and value category of an expression.

So, It deduces type of things.size() and i will be a type as same as things.size(). So, i < things.size() will be executed without any warning

Great solution but for my Windows I need make a modifications. Below the modify code

function Zip($source, $destination){

if (!extension_loaded('zip') || !file_exists($source)) {
    return false;
}

$zip = new ZipArchive();
if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
    return false;
}

$source = str_replace('\\', '/', realpath($source));

if (is_dir($source) === true)
{
    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);

    foreach ($files as $file)
    {
        $file = str_replace('\\', '/', $file);

        // Ignore "." and ".." folders
        if( in_array(substr($file, strrpos($file, '/')+1), array('.', '..')) )
            continue;

        if (is_dir($file) === true)
        {
            $zip->addEmptyDir(str_replace($source . '/', '', $file));
        }
        else if (is_file($file) === true)
        {

            $str1 = str_replace($source . '/', '', '/'.$file);
            $zip->addFromString($str1, file_get_contents($file));

        }
    }
}
else if (is_file($source) === true)
{
    $zip->addFromString(basename($source), file_get_contents($source));
}

return $zip->close();
}

You are not indicating what to include in the archive.

Go one level outside your folder and try:

sudo tar -cvjSf folder.tar.bz2 folder

Or from the same folder try

sudo tar -cvjSf folder.tar.bz2 *

The code posted by Owen can tell you the information mentioned by a number of the other answers here:

public void simpleExample ()
{
    FileInputStream fis = new FileInputStream ("mytest.class");
    parseJavaClassFile ( fis );
}
protected void parseJavaClassFile ( InputStream classByteStream ) throws Exception
{
    DataInputStream dataInputStream = new DataInputStream ( classByteStream );
    magicNumber = dataInputStream.readInt();
    if ( magicNumber == 0xCAFEBABE )
    {
        int minorVer = dataInputStream.readUnsignedShort();
        int majorVer = dataInputStream.readUnsignedShort();
        // do something here with major & minor numbers
    }
}

Link to the PEP discussing the new bool type in Python 2.3: http://www.python.org/dev/peps/pep-0285/.

When converting a bool to an int, the integer value is always 0 or 1, but when converting an int to a bool, the boolean value is True for all integers except 0.

>>> int(False)
0
>>> int(True)
1
>>> bool(5)
True
>>> bool(-5)
True
>>> bool(0)
False

If you want to pick cell entries from a list then you have a couple of non-code based options

• Data Validation, which is very well covered at Debra Dalgleish's site
• Excel's autocomplete feature

I would recommend The Data Validation approach where

• creating a list of your 100 records in a single column,
• provide a range name to this list,
• then using Data Validation's List option

sample from Debra's site below, click on the first link above to access it.

I think the question is not 100% answered. I was searching for issue with missing typeof(), which is compile time directive.

as of conculsion try to use __typeof__() instead. Also gcc ... -Dtypeof=__typeof__ ... can help.

Sorry you're not using PostgreSQL...

SELECT DISTINCT ON contract, activity * FROM thetable ORDER BY contract, activity

Oh wait. You only want values with exactly one...

SELECT contract, activity, count() FROM thetable GROUP BY contract, activity HAVING count() = 1

Always try to log in using those credentials with SQL Management Studio. This might reveal some more details that you don't get at runtime in your code. I had checked the SQL + Windows authentication, restarted the server but still no luck. After trying to log in using SQL Management, I got this prompt:

Somehow the password had expired although the login was created just minutes before. Anyway, new password set, connection string updated and all's fine.

Check if you have something configured inside the config file /application/config/config.php e.g.

$config['base_url'] = 'http://example.com/';

this works for ubuntu 15.10:

sudo locale-gen "en_US.UTF-8"
sudo dpkg-reconfigure locales

Usually in case of "ImagePullBackOff" it's retried after few seconds/minutes. In case you want to try again manually you can delete the old pod and recreate the pod. The one line command to delete and recreate the pod would be:

kubectl replace --force -f <yml_file_describing_pod>

Update: As of November, 2020, Gitlens appears within VSCode's builtin Source Control Panel

I would recommend to use: Git Lens.

You can use the sorted method with a key.

sorted(a, key=lambda x : x[1])

Use:

/* @var $objs Test[] */
foreach ($objs as $obj) {
    // Typehinting will occur after typing $obj->
}

when typehinting inline variables, and

class A {
    /** @var Test[] */
    private $items;
}

for class properties.

Previous answer from '09 when PHPDoc (and IDEs like Zend Studio and Netbeans) didn't have that option:

The best you can do is say,

foreach ($Objs as $Obj)
{
    /* @var $Obj Test */
    // You should be able to get hinting after the preceding line if you type $Obj->
}

I do that a lot in Zend Studio. Don't know about other editors, but it ought to work.

http://en.wikipedia.org/wiki/Division_by_zero

http://en.wikipedia.org/wiki/Unix_signal#SIGFPE

This should give you a really good idea. Since a modulus is, in its basic sense, division with a remainder, something % 0 IS division by zero and as such, will trigger a SIGFPE being thrown.

Byte swapping with ye olde 3-step-xor trick around a pivot in a template function gives a flexible, quick O(ln2) solution that does not require a library, the style here also rejects 1 byte types:

template<typename T>void swap(T &t){
    for(uint8_t pivot = 0; pivot < sizeof(t)/2; pivot ++){
        *((uint8_t *)&t + pivot) ^= *((uint8_t *)&t+sizeof(t)-1- pivot);
        *((uint8_t *)&t+sizeof(t)-1- pivot) ^= *((uint8_t *)&t + pivot);
        *((uint8_t *)&t + pivot) ^= *((uint8_t *)&t+sizeof(t)-1- pivot);
    }
}

A little bit easier and it looks exactly like the button in the form. Just use the input and wrap the anchor tag around it.

<a href="#"><input type="button" value="Button Text"></a>

The problem is that tick() needs to know the definition of tile_tree_apple, but all it has is a forward declaration of it. You should separate the declarations and definitions like so:

tile_tree.h

#ifndef TILE_TREE_H
#define TILE_TREE_H
#include "tile.h"

class tile_tree : public tile
{
public:
    tile onDestroy();
    tile tick();
    void onCreate();
};

#endif

tile_tree.cpp:

tile tile_tree::onDestroy() {
    return *new tile_grass;
}

tile tile_tree::tick() {
     if (rand() % 20 == 0)
         return *new tile_tree_apple;
}

void tile_tree::onCreate() {
    health = rand() % 5 + 4;
    type = TILET_TREE;
}

Except you have a major problem: you’re allocating memory (with new), then copying the allocated object and returning the copy. This is called a memory leak, because there’s no way for your program to free the memory it uses. Not only that, but you’re copying a tile_tree into a tile, which discards the information that makes a tile_tree different from a tile; this is called slicing.

What you want is to return a pointer to a new tile, and make sure you call delete at some point to free the memory:

tile* tile_tree::tick() {
     if (rand() % 20 == 0)
         return new tile_tree_apple;
}

Even better would be to return a smart pointer that will handle the memory management for you:

#include <memory>

std::shared_ptr<tile> tile_tree::tick() {
     if (rand() % 20 == 0)
         return std::make_shared<tile_tree_apple>();
}

Try this:

ApplicationContext context = new ClassPathXmlApplicationContext("app-context.xml");

The other answers address the question asked. I will address the underlying cause: poor schema design.

Do not splay an array across columns. Here you have 3*10 columns that should be turned into 10 rows of 3 columns in a new table (plus id, etc)

Your Main table would have only

id  int(11) No       
name    text    No       
date    date    No       
time    time    No       
schedule    int(11) No       
category    int(11) No       
status  int(11) No       
admin_id    int(11) No 

Your extra table (Top) would have

id  int(11) No          -- for joining to Main
seq TINYINT UNSIGNED    -- containing 1..10
img   varchar(255)    No       
title varchar(255)    No       
desc  text    No    
PRIMARY KEY(id, seq)    -- so you can easily find the 10 top_titles

There would be 10 (or fewer? or more?) rows in Top for each id.

This eliminates your original problem, and cleans up the schema. (This is not "normalization", as debated in some of the Comments.)

Do not switch to MyISAM; it is going away.
Don't worry about ROW_FORMAT.

You will need to change your code to do the JOIN and to handle multiple rows instead of multiple columns.

I had previously uninstall Java 6 and install Java 7, Android Studio was working okay, then I upgraded Android Studio and I had the issue everyone is having. Today, I uninstalled Java 7 and installed Java 8 from Oracle. Then I uninstall Android Studio and installed the latest. Everything is working for me now

This sub will populate a Collection with all files matching the filename or pattern you pass in.

Sub GetFiles(StartFolder As String, Pattern As String, _
             DoSubfolders As Boolean, ByRef colFiles As Collection)

    Dim f As String, sf As String, subF As New Collection, s
    
    If Right(StartFolder, 1) <> "\" Then StartFolder = StartFolder & "\"
    
    f = Dir(StartFolder & Pattern)
    Do While Len(f) > 0
        colFiles.Add StartFolder & f
        f = Dir()
    Loop
    
    If DoSubfolders then
        sf = Dir(StartFolder, vbDirectory)
        Do While Len(sf) > 0
            If sf <> "." And sf <> ".." Then
                If (GetAttr(StartFolder & sf) And vbDirectory) <> 0 Then
                        subF.Add StartFolder & sf
                End If
            End If
            sf = Dir()
        Loop
    
        For Each s In subF
            GetFiles CStr(s), Pattern, True, colFiles
        Next s

As described here, there is an existing method in the matplotlib.pyplot figure class that automatically rotates dates appropriately for you figure.

You can call it after you plot your data (i.e.ax.plot(dates,ydata) :

fig.autofmt_xdate()

If you need to format the labels further, checkout the above link.

Non-datetime objects

As per languitar's comment, the method I suggested for non-datetime xticks would not update correctly when zooming, etc. If it's not a datetime object used as your x-axis data, you should follow Tommy's answer:

for tick in ax.get_xticklabels():
    tick.set_rotation(45)

you can change your port in app.js or in ur project configuration file.

default('port', 80)

and to see if port 80 is already in use you can do

netstat -antp |grep 80

netstat -antp |grep node

you might wanna see if node process is already running or not.

ps -ef |grep node

and if you find its already running, you can kill it using

killall node

I wrote this little method lastly in my program so I can check if a string is numeric or at least every single char is a number.

private boolean isNumber(String text){
    if(text != null || !text.equals("")) {
        char[] characters = text.toCharArray();
        for (int i = 0; i < text.length(); i++) {
            if (characters[i] < 48 || characters[i] > 57)
                return false;
        }
    }
    return true;
}

Does this work?

I was trying to find a better answer that was more standalone, so I started to think about how JQuery does events and custom events. Since click (from JQuery) is just any event, I thought that all I had to do was trigger the event given that the iframe's content has been clicked on. Thus, this was my solution

$(document).ready(function () {
    $("iframe").each(function () {
        //Using closures to capture each one
        var iframe = $(this);
        iframe.on("load", function () { //Make sure it is fully loaded
            iframe.contents().click(function (event) {
                iframe.trigger("click");
            });
        });

        iframe.click(function () {
            //Handle what you need it to do
        });
    });
});

You can also use awk for these purposes, since it allows you to perform more complex checks in a clearer way:

Lines not containing foo:

awk '!/foo/'

Lines containing neither foo nor bar:

awk '!/foo/ && !/bar/'

Lines containing neither foo nor bar which contain either foo2 or bar2:

awk '!/foo/ && !/bar/ && (/foo2/ || /bar2/)'

And so on.

Just adding android:background="?attr/selectableItemBackgroundBorderless" should work if you don't have background color, but don't forget to use setSelected method. If you have different background color, I just used this (I'm using data-binding);

b.setIsSelected(true);

And add this to xml;

android:background="@{ isSelected ? @color/{color selected} : @color/{color not selected} }"

I have a simple solution for you!

{{ form.data.email }}

I tried this and it worked. This requires your view to populate the form class with the POST data.

Very simple example:

def your_view(request):
  if request.method == 'POST':
    form = YourForm(request.POST)
    if form.is_valid():
      # some code here
  else:
    form = YourForm()

  return render_to_response('template.html', {'form':form})

Hope that helps you. If you have any questions please let me know.

Use the <button> tag instead. <button> labels are vertically centered by default.

If you get the "Failed to find DDMS files..." do this:

1. Open eclipse
2. Open install new software
3. Click "Add..." -> type in (e.g.) "Android_over_HTTP" and in address put "http://dl-ssl.google.com/android/eclipse/".

Don't be alarmed that its not https, this helps to fetch stuff over http. This trick helped me to resolve the issue on MAC, I believe that this also should work on Windows / Linux

Hope this helps !

Well, that's easy. The purpose of lambda expression is to implement Functional Interface. It is the interface with only one method. Here is awesone article about predefined and legacy functional interfaces.

Anyway, if you want to implement your own functional interface, make it. Just for simple example:

public interface MyFunctionalInterface {
    String makeIt(String s);
}

So let's make a class, where we will create a method, which accepts the type of MyFunctionalInterface :

public class Main {

    static void printIt(String s, MyFunctionalInterface f) {
        System.out.println(f.makeIt(s));
    }

    public static void main(String[] args) {

    }
}

The last thing you should do is to pass the implementation of the MyFunctionalInterface to the method we've defined:

public class Main {

    static void printIt(String s, MyFunctionalInterface f) {
        System.out.println(f.makeIt(s));
    }

    public static void main(String[] args) {
        printIt("Java", s -> s + " is Awesome");
    }
}

That's it!

To anyone who had been wonderstruck about some files being easily uploaded and some not, it could be a size issue. I'm sharing this as I was stuck with my PHP code not uploading large files and I kept assuming it wasn't uploading any Excel files. So, if you are using PHP and you want to increase the file upload limit, go to the php.ini file and make the following modifications:

• upload_max_filesize = 2M

to be changed to

• upload_max_filesize = 10M

• post_max_size = 10M

or the size required. Then restart the Apache server and the upload will start magically working. Hope this will be of help to someone.

You can hide the input file tag using normal CSS.
First, add a label with for attribute and assign it to input button.
Now by default when you click the label, the button click event will be triggered that will open up the browse files dialogue.

<input type="file" name="imageUpload" id="imageUpload" class="hide"/> 
<label for="imageUpload" class="button-style">Select file</label>

Add the style to the label as a button.

You can either add or replace fragment in your activity. Create a FrameLayout in activity layout xml file.

Then do this in your activity to add fragment:

FragmentManager manager = getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.add(R.id.container,YOUR_FRAGMENT_NAME,YOUR_FRAGMENT_STRING_TAG);
transaction.addToBackStack(null);
transaction.commit();

And to replace fragment do this:

FragmentManager manager = getFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.container,YOUR_FRAGMENT_NAME,YOUR_FRAGMENT_STRING_TAG);
transaction.addToBackStack(null);
transaction.commit();

See Android documentation on adding a fragment to an activity or following related questions on SO:

Classes and structures must set all of their stored properties to an appropriate initial value by the time an instance of that class or structure is created. Stored properties cannot be left in an indeterminate state.

You get the error message Class "HomeCell" has no initializers because your variables is in an indeterminate state. Either you create initializers or you make them optional types, using ! or ?

While binding a databound control, you can evaluate a field of the row in your data source with eval() function.

For example you can add a column to your gridview like that :

<asp:BoundField DataField="YourFieldName" />

And alternatively, this is the way with eval :

<asp:TemplateField>
<ItemTemplate>
        <asp:Label ID="lbl" runat="server" Text='<%# Eval("YourFieldName") %>'>
        </asp:Label>
</ItemTemplate>
</asp:TemplateField>

It seems a little bit complex, but it's flexible, because you can set any property of the control with the eval() function :

<asp:TemplateField>
    <ItemTemplate>
        <asp:HyperLink ID="HyperLink1" runat="server" 
          NavigateUrl='<%# "ShowDetails.aspx?id="+Eval("Id") %>' 
          Text='<%# Eval("Text", "{0}") %>'></asp:HyperLink>
    </ItemTemplate>
</asp:TemplateField>

For scenarios that you don't have an ngApp that contains the title tag, just inject a service to controllers that need to set the window title.

var app = angular.module('MyApp', []);

app.controller('MyController', function($scope, SomeService, Title){
    var serviceData = SomeService.get();
    Title.set("Title of the page about " + serviceData.firstname);
});

app.factory('SomeService', function ($window) {
    return {
        get: function(){
            return { firstname : "Joe" };
        }
    };
});

app.factory('Title', function ($window) {
    return {
        set: function(val){
            $window.document.title = val;
        }
    };
});

I posted some code in answer to a related question on StackOverflow:

Sorting a multidimensionnal array in VBA

The code samples in that thread include:

1. A vector array Quicksort;
2. A multi-column array QuickSort;
3. A BubbleSort.

Alain's optimised Quicksort is very shiny: I just did a basic split-and-recurse, but the code sample above has a 'gating' function that cuts down on redundant comparisons of duplicated values. On the other hand, I code for Excel, and there's a bit more in the way of defensive coding - be warned, you'll need it if your array contains the pernicious 'Empty()' variant, which will break your While... Wend comparison operators and trap your code in an infinite loop.

Note that quicksort algorthms - and any recursive algorithm - can fill the stack and crash Excel. If your array has fewer than 1024 members, I'd use a rudimentary BubbleSort.

PATH mode is used in generating XML from a SELECT query

1. SELECT   
       ID,  
       Name  
FROM temp1
FOR XML PATH;  

Ouput:
<row>
<ID>1</ID>
<Name>aaa</Name>
</row>

<row>
<ID>1</ID>
<Name>bbb</Name>
</row>

<row>
<ID>1</ID>
<Name>ccc</Name>
</row>

<row>
<ID>1</ID>
<Name>ddd</Name>
</row>

<row>
<ID>1</ID>
<Name>eee</Name>
</row>

The Output is element-centric XML where each column value in the resulting rowset is wrapped in an row element. Because the SELECT clause does not specify any aliases for the column names, the child element names generated are the same as the corresponding column names in the SELECT clause.

For each row in the rowset a tag is added.

2.
SELECT   
       ID,  
       Name  
FROM temp1
FOR XML PATH('');

Ouput:
<ID>1</ID>
<Name>aaa</Name>
<ID>1</ID>
<Name>bbb</Name>
<ID>1</ID>
<Name>ccc</Name>
<ID>1</ID>
<Name>ddd</Name>
<ID>1</ID>
<Name>eee</Name>

For Step 2: If you specify a zero-length string, the wrapping element is not produced.

3. 

    SELECT   

           Name  
    FROM temp1
    FOR XML PATH('');

    Ouput:
    <Name>aaa</Name>
    <Name>bbb</Name>
    <Name>ccc</Name>
    <Name>ddd</Name>
    <Name>eee</Name>

4. SELECT   
        ',' +Name  
FROM temp1
FOR XML PATH('')

Ouput:
,aaa,bbb,ccc,ddd,eee

In Step 4 we are concatenating the values.

5. SELECT ID,
    abc = (SELECT   
            ',' +Name  
    FROM temp1
    FOR XML PATH('') )
FROM temp1

Ouput:
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee


6. SELECT ID,
    abc = (SELECT   
            ',' +Name  
    FROM temp1
    FOR XML PATH('') )
FROM temp1 GROUP by iD

Ouput:
ID  abc
1   ,aaa,bbb,ccc,ddd,eee

In Step 6 we are grouping the date by ID.

STUFF( source_string, start, length, add_string ) Parameters or Arguments source_string The source string to modify. start The position in the source_string to delete length characters and then insert add_string. length The number of characters to delete from source_string. add_string The sequence of characters to insert into the source_string at the start position.

SELECT ID,
    abc = 
    STUFF (
        (SELECT   
                ',' +Name  
        FROM temp1
        FOR XML PATH('')), 1, 1, ''
    )
FROM temp1 GROUP by iD

Output:
-----------------------------------
| Id        | Name                |
|---------------------------------|

I created an Interface and a <options> tag helper for this. So I didn't have to convert the IEnumerable<T> items into IEnumerable<SelectListItem> every time I have to populate the <select> control.

And I think it works beautifully...

The usage is something like:

<select asp-for="EmployeeId">
    <option value="">Please select...</option>
    <options asp-items="@Model.EmployeesList" />
</select>

And to make it work with the tag helper you have to implement that interface in your class:

public class Employee : IIntegerListItem
{
   public int Id { get; set; }
   public string FullName { get; set; }

   public int Value { return Id; }
   public string Text{ return FullName ; }
}

These are the needed codes:

The interface:

public interface IIntegerListItem
{
    int Value { get; }
    string Text { get; }
}

The <options> tag helper:

[HtmlTargetElement("options", Attributes = "asp-items")]
public class OptionsTagHelper : TagHelper
{
    public OptionsTagHelper(IHtmlGenerator generator)
    {
        Generator = generator;
    }

    [HtmlAttributeNotBound]
    public IHtmlGenerator Generator { get; set; }

    [HtmlAttributeName("asp-items")]
    public object Items { get; set; }

    public override void Process(TagHelperContext context, TagHelperOutput output)
    {
        output.SuppressOutput();
        // Is this <options /> element a child of a <select/> element the SelectTagHelper targeted?
        object formDataEntry;
        context.Items.TryGetValue(typeof(SelectTagHelper), out formDataEntry);

        var selectedValues = formDataEntry as ICollection<string>;
        var encodedValues = new HashSet<string>(StringComparer.OrdinalIgnoreCase);
        if (selectedValues != null && selectedValues.Count != 0)
        {
            foreach (var selectedValue in selectedValues)
            {
                encodedValues.Add(Generator.Encode(selectedValue));
            }
        }

        IEnumerable<SelectListItem> items = null;
        if (Items != null)
        {
            if (Items is IEnumerable)
            {
                var enumerable = Items as IEnumerable;
                if (Items is IEnumerable<SelectListItem>)
                    items = Items as IEnumerable<SelectListItem>;
                else if (Items is IEnumerable<IIntegerListItem>)
                    items = ((IEnumerable<IIntegerListItem>)Items).Select(x => new SelectListItem() { Selected = false, Value = ((IIntegerListItem)x).Value.ToString(), Text = ((IIntegerListItem)x).Text });
                else
                    throw new InvalidOperationException(string.Format("The {2} was unable to provide metadata about '{1}' expression value '{3}' for <options>.",
                        "<options>",
                        "ForAttributeName",
                        nameof(IModelMetadataProvider),
                        "For.Name"));
            }
            else
            {
                throw new InvalidOperationException("Invalid items for <options>");
            }

            foreach (var item in items)
            {
                bool selected = (selectedValues != null && selectedValues.Contains(item.Value)) || encodedValues.Contains(item.Value);
                var selectedAttr = selected ? "selected='selected'" : "";

                if (item.Value != null)
                    output.Content.AppendHtml($"<option value='{item.Value}' {selectedAttr}>{item.Text}</option>");
                else
                    output.Content.AppendHtml($"<option>{item.Text}</option>");
            }
        }
    }
}

There may be some typo but the aim is clear I think. I had to edit a little bit.

In case you are dealing with a legacy system, or you have too many places to switch to PreparedStatements in too little time - i.e. if there is an obstacle to using the best practice suggested by other answers, you can try AntiSQLFilter

I got a GPU called NVIDIA GTX GeForce 1650 Ti in my machine with tensorflow-gpu==2.2.0

Run the following two lines of code:

import tensorflow as tf
print("Num GPUs Available: ", len(tf.config.experimental.list_physical_devices('GPU')))

Output:

Num GPUs Available:  1

It's the end of 2020, thanks to modern javascript, node.js and browsers support, we can get out of 3rd-party library whirlpool (jquery, query-string etc.) and DRY ourselves.

Here are javascript(node.js) and typescript version for a function that adds or updates query params of given url:

Javascript

const getUriWithParam = (baseUrl, params) => {
  const Url = new URL(baseUrl);
  let urlParams = new URLSearchParams(Url.search);
  for (const key in params) {
    if (params[key] !== undefined) {
      urlParams.set(key, params[key]);
    }
  }
  Url.search = urlParams.toString();
  return Url.toString();
};

console.info('expected: https://example.com/?foo=bar');
console.log(getUriWithParam("https://example.com", {foo: "bar"}));

console.info('expected: https://example.com/slug?foo=bar#hash');
console.log(getUriWithParam("https://example.com/slug#hash", {foo: "bar"}));

console.info('expected: https://example.com/?bar=baz&foo=bar');
console.log(getUriWithParam("https://example.com?bar=baz", {foo: "bar"}));

console.info('expected: https://example.com/?foo=baz&bar=baz');
console.log(getUriWithParam("https://example.com?foo=bar&bar=baz", {foo: "baz"}));

Typescript

type RequestParamType = {
  [key: string]: any;
};

const getUriWithParam = (
  baseUrl: string,
  params: RequestParamType
): string => {
  const Url = new URL(baseUrl);
  let urlParams: URLSearchParams = new URLSearchParams(Url.search);
  for (const key in params) {
    if (params[key] !== undefined) {
      urlParams.set(key, params[key]);
    }
  }
  Url.search = urlParams.toString();
  return Url.toString();
};

i just encountered this problem now and with some tries i figured out that visiting services >> select MySQLxx service , then right click and hit start , that solved my problem and everything is working without the need to loss data.

You could use...

<option <?= ($temp == $value) ? "SELECTED" : "" ?> >$value</opton>

Edit: I thought I was looking at PHP questions... Sorry.

Make sure the MySQL service is running on your machine, then follow the instructions from MySQL for initially setting up root (search for 'windows' and it will take you to the steps for setting up root):

http://dev.mysql.com/doc/refman/5.1/en/default-privileges.html

It seems you may be more comfortable with developing in PHP you let this hold you back from utilizing the full potential with web applications.

It is indeed possible to have PHP render partials and whole views, but I would not recommend it.

To fully utilize the possibilities of HTML and javascript to make a web application, that is, a web page that acts more like an application and relies heavily on client side rendering, you should consider letting the client maintain all responsibility of managing state and presentation. This will be easier to maintain, and will be more user friendly.

I would recommend you to get more comfortable thinking in a more API centric approach. Rather than having PHP output a pre-rendered view, and use angular for mere DOM manipulation, you should consider having the PHP backend output the data that should be acted upon RESTFully, and have Angular present it.

Using PHP to render the view:

/user/account

if($loggedIn)
{
    echo "<p>Logged in as ".$user."</p>";
}
else
{
    echo "Please log in.";
}

How the same problem can be solved with an API centric approach by outputting JSON like this:

api/auth/

{
  authorized:true,
  user: {
      username: 'Joe', 
      securityToken: 'secret'
  }
}

and in Angular you could do a get, and handle the response client side.

$http.post("http://example.com/api/auth", {})
.success(function(data) {
    $scope.isLoggedIn = data.authorized;
});

To blend both client side and server side the way you proposed may be fit for smaller projects where maintainance is not important and you are the single author, but I lean more towards the API centric way as this will be more correct separation of conserns and will be easier to maintain.

Simple way to initiate the message on startup:

bot.on('ready', () => {
    bot.user.setStatus('available')
    bot.user.setPresence({
        game: {
            name: 'with depression',
            type: "STREAMING",
            url: "https://www.twitch.tv/monstercat"
        }
    });
});

You can also just declare it elsewhere after startup, to change the message as needed:

bot.user.setPresence({ game: { name: 'with depression', type: "streaming", url: "https://www.twitch.tv/monstercat"}}); 

You could wrap setInterval() in a function that provides that behavior:

function instantGratification( fn, delay ) {
    fn();
    setInterval( fn, delay );
}

...then use it like this:

instantGratification( function() {
    console.log( 'invoked' );
}, 3000);

Have a look at ACL WordUtils.

WordUtils.capitalize("your string") == "Your String"

Create the war file in a different directory to where the content is otherwise the jar command might try to zip up the file it is creating.

#!/bin/bash

set -euo pipefail

war=app.war
src=contents

# Clean last war build
if [ -e ${war} ]; then
    echo "Removing old war ${war}"
    rm -rf ${war}
fi

# Build war
if [ -d ${src} ]; then
    echo "Found source at ${src}"
    cd ${src}
    jar -cvf ../${war} *
    cd ..
fi

# Show war details
ls -la ${war}

Tried to use the solution proposed by Misko, but in my situation, some attributes, which needed to be merged into my template html, were themselves directives.

Unfortunately, not all of the directives referenced by the resulting template did work correctly. I did not have enough time to dive into angular code and find out the root cause, but found a workaround, which could potentially be helpful.

The solution was to move the code, which creates the template html, from compile to a template function. Example based on code from above:

    angular.module('formComponents', [])
  .directive('formInput', function() {
    return {
        restrict: 'E',
        template: function(element, attrs) {
           var type = attrs.type || 'text';
            var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
            var htmlText = '<div class="control-group">' +
                '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                    '<div class="controls">' +
                    '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                    '</div>' +
                '</div>';
             return htmlText;
        }
        compile: function(element, attrs)
        {
           //do whatever else is necessary
        }
    }
})

Add to your JS:

jQuery(document).ready(function($) {
  $("body").css({
    'padding-top': $(".navbar").outerHeight() + 'px'
  })
});

WebClient to fetch the contents from the remote url and JavaScriptSerializer or Json.NET to deserialize the JSON into a .NET object. For example you define a model class which will reflect the JSON structure and then:

using (var client = new WebClient())
{
    var json = client.DownloadString("http://example.com/json");
    var serializer = new JavaScriptSerializer();
    SomeModel model = serializer.Deserialize<SomeModel>(json);
    // TODO: do something with the model
}

There are also some REST client frameworks you may checkout such as RestSharp.

For docker-compose. In the docker-compose.yml:

version: '3'
services:
    app:
        image: ...
        user: ${UID:-0}
...

In .env:

UID=1000

Quick and easy, add this to your page:

<style>
    .select2-results {
        max-height: 500px;
    }
</style>

There is: Path.ChangeExtension method. E.g.:

var result = Path.ChangeExtension(myffile, ".jpg");

In the case if you also want to physically change the extension, you could use File.Move method:

File.Move(myffile, Path.ChangeExtension(myffile, ".jpg"));

You might have output (maybe error/debug output) that precedes your call to

header("Content-type: text/xml");

Therefore, the content being delivered to the browser is not "xml"... that's what the error message is trying to tell you (at least that was the case for me and I had the same error message as you've described).

Well, note that the request contains binary data, so I'm not posting the request as such - instead, I've converted every non-printable-ascii character into a dot (".").

For all of those, who still experiencing this problem, I just spent 2 days tracking down the bloody thing. I was getting the same error when there was no rows in dataset. Seems obvious, but error message is very obscure, hence 2 days.

import httr package

library(httr)

Get the url

url <- "http://www.omdbapi.com/?apikey=72bc447a&t=Annie+Hall&y=&plot=short&r=json"
resp <- GET(url)

Print content of resp as text

content(resp, as = "text")

Print content of resp

content(resp)

Use content() to get the content of resp, but this time do not specify a second argument. R figures out automatically that you're dealing with a JSON, and converts the JSON to a named R list.

The two syntaxes are not equivalent and it can lead to unexpected errors. Here is a simple example showing the differences. If you have a model:

from django.db import models

class Test(models.Model):

    added = models.DateTimeField(auto_now_add=True)

And you create a first object:

foo = Test.objects.create(pk=1)

Then you try to create an object with the same primary key:

foo_duplicate = Test.objects.create(pk=1)
# returns the error:
# django.db.utils.IntegrityError: (1062, "Duplicate entry '1' for key 'PRIMARY'")

foo_duplicate = Test(pk=1).save()
# returns the error:
# django.db.utils.IntegrityError: (1048, "Column 'added' cannot be null")

It's much easier to do like this:

if(!$('#foo').hasClass('bar')) { 
  ...
}

The ! in front of the criteria means false, works in most programming languages.

IF your data won't overflow 4000 characters AND you're on SQL Server 2000 or compatibility level of 8 or SQL Server 2000:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(4000)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

For SQL Server 2005+:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(MAX)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%'

After looking through all the answers, I found a slightly different way with minimum CSS and no JS, only the height of the header needs to be set correctly in #content, in this case 60px

CSS:

#header {
  position: fixed;
  width: 100%;
  top: 0;
  z-index: 10;
}
#content {
  margin-top: 60px;
  z-index:1;
}

HTML:

<body>
  <div id="header" style="background-color:GRAY; text-align:center; border-bottom:1px SOLID BLACK; color:WHITE; line-height:50px; font-size:40px">
     My Large Static Header
  </div>
  <div id="content">
     <!-- All page content here -->
  </div>
</body>

This problem occurs if there are different jar versions. Especially versions of httpcore and httpclient. Use same versions of httpcore and httpclient.

Here is my version. It stores data based on categories.

import matplotlib.pyplot as plt
import numpy as np

data_a = [[1,2,5], [5,7,2,2,5], [7,2,5]]
data_b = [[6,4,2], [1,2,5,3,2], [2,3,5,1]]

ticks = ['A', 'B', 'C']

def set_box_color(bp, color):
    plt.setp(bp['boxes'], color=color)
    plt.setp(bp['whiskers'], color=color)
    plt.setp(bp['caps'], color=color)
    plt.setp(bp['medians'], color=color)

plt.figure()

bpl = plt.boxplot(data_a, positions=np.array(xrange(len(data_a)))*2.0-0.4, sym='', widths=0.6)
bpr = plt.boxplot(data_b, positions=np.array(xrange(len(data_b)))*2.0+0.4, sym='', widths=0.6)
set_box_color(bpl, '#D7191C') # colors are from http://colorbrewer2.org/
set_box_color(bpr, '#2C7BB6')

# draw temporary red and blue lines and use them to create a legend
plt.plot([], c='#D7191C', label='Apples')
plt.plot([], c='#2C7BB6', label='Oranges')
plt.legend()

plt.xticks(xrange(0, len(ticks) * 2, 2), ticks)
plt.xlim(-2, len(ticks)*2)
plt.ylim(0, 8)
plt.tight_layout()
plt.savefig('boxcompare.png')

I am short of reputation so I cannot post an image to here. You can run it and see the result. Basically it's very similar to what Molly did.

Note that, depending on the version of python you are using, you may need to replace xrange with range

Using Bash.

$ var1="1:2:3:4:0"
$ IFS=":"
$ set -- $var1
$ eval echo  \$${#}

As mentioned in "Polling must die: triggering Jenkins builds from a git hook", you can notify Jenkins of a new commit:

With the latest Git plugin 1.1.14 (that I just release now), you can now do this more >easily by simply executing the following command:

curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>

This will scan all the jobs that’s configured to check out the specified URL, and if they are also configured with polling, it’ll immediately trigger the polling (and if that finds a change worth a build, a build will be triggered in turn.)

This allows a script to remain the same when jobs come and go in Jenkins.
Or if you have multiple repositories under a single repository host application (such as Gitosis), you can share a single post-receive hook script with all the repositories. Finally, this URL doesn’t require authentication even for secured Jenkins, because the server doesn’t directly use anything that the client is sending. It runs polling to verify that there is a change, before it actually starts a build.

As mentioned here, make sure to use the right address for your Jenkins server:

since we're running Jenkins as standalone Webserver on port 8080 the URL should have been without the /jenkins, like this:

http://jenkins:8080/git/notifyCommit?url=git@gitserver:tools/common.git

To reinforce that last point, ptha adds in the comments:

It may be obvious, but I had issues with:

curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>. 

The url parameter should match exactly what you have in Repository URL of your Jenkins job.
When copying examples I left out the protocol, in our case ssh://, and it didn't work.

You can also use a simple post-receive hook like in "Push based builds using Jenkins and GIT"

#!/bin/bash
/usr/bin/curl --user USERNAME:PASS -s \

http://jenkinsci/job/PROJECTNAME/build?token=1qaz2wsx

Configure your Jenkins job to be able to “Trigger builds remotely” and use an authentication token (1qaz2wsx in this example).

However, this is a project-specific script, and the author mentions a way to generalize it.
The first solution is easier as it doesn't depend on authentication or a specific project.

I want to check in change set whether at least one java file is there the build should start.
Suppose the developers changed only XML files or property files, then the build should not start.

Basically, your build script can:

• put a 'build' notes (see git notes) on the first call
• on the subsequent calls, grab the list of commits between HEAD of your branch candidate for build and the commit referenced by the git notes 'build' (git show refs/notes/build): git diff --name-only SHA_build HEAD.
• your script can parse that list and decide if it needs to go on with the build.
• in any case, create/move your git notes 'build' to HEAD.

May 2016: cwhsu points out in the comments the following possible url:

you could just use curl --user USER:PWD http://JENKINS_SERVER/job/JOB_NAME/build?token=YOUR_TOKEN if you set trigger config in your item

June 2016, polaretto points out in the comments:

I wanted to add that with just a little of shell scripting you can avoid manual url configuration, especially if you have many repositories under a common directory.
For example I used these parameter expansions to get the repo name

repository=${PWD%/hooks}; 
repository=${repository##*/} 

and then use it like:

curl $JENKINS_URL/git/notifyCommit?url=$GIT_URL/$repository

For me this error was due to the command prompt, which was not running under administrator privileges. You need to right click on the command prompt and say "Run as administrator".

You need administrator role to install or uninstall a service.

    </thead>
    <tbody>
      <tr ng-repeat="(key, value) in vm.records">
        <td ng-repeat="(key, value) in value">
          {{value}}
        </td>
      </tr>
    </tbody>
</table>

LEFT is not a function in Oracle. This probably came from someone familiar with SQL Server:

Returns the left part of a character string with the specified number of characters.

-- Syntax for SQL Server, Azure SQL Database, Azure SQL Data Warehouse, Parallel Data Warehouse  
LEFT ( character_expression , integer_expression )  

ok , i've solved it by creating a handler on the onCreate of the service , and calling the gps functions through there .

The code is as simple as this:

final handler=new Handler(Looper.getMainLooper()); 

And then to force running things on the UI, I call post on it.

This should work:

$("label[for='comedyclubs']")

Just add "Container(width: 5, color: Colors.transparent)," between elements

new Container(
      alignment: FractionalOffset.center,
      child: new Row(
        mainAxisAlignment: MainAxisAlignment.spaceEvenly,
        children: <Widget>[
          new FlatButton(
            child: new Text('Don\'t have an account?', style: new TextStyle(color: Color(0xFF2E3233))),
          ),
            Container(width: 5, color: Colors.transparent),
          new FlatButton(
            child: new Text('Register.', style: new TextStyle(color: Color(0xFF84A2AF), fontWeight: FontWeight.bold),),
            onPressed: moveToRegister,
          )
        ],
      ),
    ),  

Based on A.K's code, here is a Helper Function. JS Fiddle Here (http://jsfiddle.net/M5vsL/1/) ...

// Helper Method Defined Here.
(function (helper, $) {
    // This is now a utility function to "Get the Document Hash"
    helper.getDocumentHash = function (urlString) {
        var hashValue = "";

        if (urlString.indexOf('#') != -1) {
            hashValue = urlString.substring(parseInt(urlString.indexOf('#')) + 1);
        }
        return hashValue;
    };
})(this.helper = this.helper || {}, jQuery);

Arrays are pretty flexible in JS, you can do:

var myArray = new Array();
myArray.push("string 1");
myArray.push("string 2");

Bit is also an option if tinyint isn't to your liking. A few links:

• Which MySQL data type to use for storing boolean values
• What is the difference between BIT and TINYINT in MySQL?

Not surprisingly, more info about numeric types is available in the manual.

One more link: http://blog.mclaughlinsoftware.com/2010/02/26/mysql-boolean-data-type/

And a quote from the comment section of the article above:

• TINYINT(1) isn’t a synonym for bit(1).
• TINYINT(1) can store -9 to 9.
• TINYINT(1) UNSIGNED: 0-9
• BIT(1): 0, 1. (Bit, literally).

Edit: This edit (and answer) is only remotely related to the original question...

Additional quotes by Justin Rovang and the author maclochlainn (comment section of the linked article).

Excuse me, seems I’ve fallen victim to substr-ism: TINYINT(1): -128-+127 TINYINT(1) UNSIGNED: 0-255 (Justin Rovang 25 Aug 11 at 4:32 pm)

True enough, but the post was about what PHPMyAdmin listed as a Boolean, and there it only uses 0 or 1 from the entire wide range of 256 possibilities. (maclochlainn 25 Aug 11 at 11:35 pm)

In my case I had to add both 'user agent' and 'default credentials = True'. I know this is pretty old, still wanted to share. Hope this helps. Below code is in powershell, but it should help others who are using c#.

[System.Net.HttpWebRequest] $req = [System.Net.HttpWebRequest]::Create($uri)
$req.UserAgent = "BlackHole"
$req.UseDefaultCredentials = $true

With Protractor, you can use the following approach

var EC = protractor.ExpectedConditions;
// Wait for new page url to contain newPageName
browser.wait(EC.urlContains('newPageName'), 10000);

So your code will look something like,

emailEl.sendKeys('jack');
passwordEl.sendKeys('123pwd');

btnLoginEl.click();

var EC = protractor.ExpectedConditions;
// Wait for new page url to contain efg
ptor.wait(EC.urlContains('efg'), 10000);

expect(ptor.getCurrentUrl()).toEqual(url + 'abc#/efg');

Note: This may not mean that new page has finished loading and DOM is ready. The subsequent 'expect()' statement will ensure Protractor waits for DOM to be available for test.

Reference: Protractor ExpectedConditions

If you are stuck on django 1.2 like I am and RedirectView doesn't exist, another route-centric way to add the redirect mapping is using:

(r'^match_rules/$', 'django.views.generic.simple.redirect_to', {'url': '/new_url'}),  

You can also re-route everything on a match. This is useful when changing the folder of an app but wanting to preserve bookmarks:

(r'^match_folder/(?P<path>.*)', 'django.views.generic.simple.redirect_to', {'url': '/new_folder/%(path)s'}),  

This is preferable to django.shortcuts.redirect if you are only trying to modify your url routing and do not have access to .htaccess, etc (I'm on Appengine and app.yaml doesn't allow url redirection at that level like an .htaccess).

If you're using some plugin which takes string and use construct Regex to create Regex Object i:e new RegExp()

Than Below string will work

'^\\S*$'

It's same regex @Bergi mentioned just the string version for new RegExp constructor

Based on the accepted answer, for those who encountered a similar issue, with full schema qualification:

([MyDataBase].[MySchemaName].[MyTable])... results in an error, you need to be in the context of that DB

That is, the following will throw an error:

DBCC CHECKIDENT ([MyDataBase].[MySchemaName].[MyTable], RESEED, 0)

Enclose the fully-qualified table name with single quotes instead:

DBCC CHECKIDENT ('[MyDataBase].[MySchemaName].[MyTable]', RESEED, 0)

Depending on what you want to do you could do this:

template<typename Base, typename T>
inline bool instanceof(const T*) {
    return std::is_base_of<Base, T>::value;
}

Use:

if (instanceof<BaseClass>(ptr)) { ... }

However, this purely operates on the types as known by the compiler.

Edit:

This code should work for polymorphic pointers:

template<typename Base, typename T>
inline bool instanceof(const T *ptr) {
    return dynamic_cast<const Base*>(ptr) != nullptr;
}

Example: http://cpp.sh/6qir

I was messing/musing on one-liners involving querySelector() & ended up here, & have a possible answer to the OP question using tag names & querySelector(), with credits to @JaredMcAteer for answering MY question, aka have RegEx-like matches with querySelector() in vanilla Javascript

Hoping the following will be useful & fit the OP's needs or everyone else's:

// basically, of before:
var youtubeDiv = document.querySelector('iframe[src="http://www.youtube.com/embed/Jk5lTqQzoKA"]')

// after     
var youtubeDiv = document.querySelector('iframe[src^="http://www.youtube.com"]');
// or even, for my needs
var youtubeDiv = document.querySelector('iframe[src*="youtube"]');

Then, we can, for example, get the src stuff, etc ...

console.log(youtubeDiv.src);
//> "http://www.youtube.com/embed/Jk5lTqQzoKA"
console.debug(youtubeDiv);
//> (...)

This is very handy when using a method that would otherwise be ambiguous. For example: JDialog has constructors with the following signatures:

JDialog(Frame, String, boolean, GraphicsConfiguration)
JDialog(Dialog, String, boolean, GraphicsConfiguration)

I need to use this constructor, because I want to set the GraphicsConfiguration, but I have no parent for this dialog, so the first argument should be null. Using

JDialog(null, String, boolean, Graphicsconfiguration) 

is ambiguous, so in this case I can narrow the call by casting null to one of the supported types:

JDialog((Frame) null, String, boolean, GraphicsConfiguration)

Like others, I had issues with Python 3.5.1/Anaconda 2.4.0 on OS X 10.11..

But I found a compatible package here:

https://anaconda.org/menpo/opencv3

It can be installed via the command line like so:

 conda install -c https://conda.anaconda.org/menpo opencv3

Worked like a charm. First time I've ever gotten OpenCV to work on 3.x!

here is a solution if you are not using jquery:

myArray = myArray.filter(function( obj ) {
  return obj.id !== id;
});

When Atom auto-indent-detection got it hopelessly wrong and refused to let me type a literal Tab character, I eventually found the 'Force-Tab' extension - which gave me back control. I wanted to keep shift-tab for outdenting, so set ctrl-tab to insert a hard tab. In my keymap I added:

'atom-text-editor': 'ctrl-tab': 'force-tab:insert-actual-tab'

NestedScrollView is just like ScrollView, but in NestedScrollView we can put other scrolling views as child of it, e.g. RecyclerView.

But if we put RecyclerView inside NestedScrollView, RecyclerView's smooth scrolling is disturbed. So to bring back smooth scrolling there's trick:

ViewCompat.setNestedScrollingEnabled(recyclerView, false);

put above line after setting adapter for recyclerView.

Here are two examples from my working project.

1. Using EntityUtils and HttpEntity

   HttpResponse response = httpClient.execute(new HttpGet(URL));
   HttpEntity entity = response.getEntity();
   String responseString = EntityUtils.toString(entity, "UTF-8");
   System.out.println(responseString);
   

2. Using BasicResponseHandler

   HttpResponse response = httpClient.execute(new HttpGet(URL));
   String responseString = new BasicResponseHandler().handleResponse(response);
   System.out.println(responseString);
   

An alterntive is to use an enum and a component class that extends the standard RadioButton.

public enum Genders
{
    Male,
    Female
}

[ToolboxBitmap(typeof(RadioButton))]
public partial class GenderRadioButton : RadioButton
{
    public GenderRadioButton()
    {
        InitializeComponent();
    }

    public GenderRadioButton (IContainer container)
    {
        container.Add(this);

        InitializeComponent();
    }

    public Genders gender{ get; set; }
}

Use a common event handler for the GenderRadioButtons

private void Gender_CheckedChanged(Object sender, EventArgs e)
{
    if (((RadioButton)sender).Checked)
    {
        //get selected value
        Genders myGender = ((GenderRadioButton)sender).Gender;
        //get the name of the enum value
        string GenderName = Enum.GetName(typeof(Genders ), myGender);
        //do any work required when you change gender
        switch (myGender)
        {
            case Genders.Male:
                break;
            case Genders.Female:
                break;
            default:
                break;
        }
    }
}

Use Array.prototype.keys:

for (const index of [1, 2, 3, 4, 5].keys()) {_x000D_
  console.log(index);_x000D_
}

If you want to access both the key and the value, you can use Array.prototype.entries() with destructuring:

for (const [index, value] of [1, 2, 3, 4, 5].entries()) {_x000D_
  console.log(index, value);_x000D_
}

Call Page_load function:

Page_Load(sender, e);

Change your gradle version in project setting: If you are using mac,click File->Project structure,then change gradle version,here:

And check your build.gradle of project,change dependency of gradle,like this:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.1'
    }
}

Why to annoy the user with three different Dialog Boxes to enter things, why not do all this in one go in a single Dialog and save time, instead of testing the patience of the USER ?

You can add everything in a single Dialog, by putting all the fields on your JPanel and then adding this JPanel to your JOptionPane. Below code can clarify a bit more :

import java.awt.*;
import java.util.*;
import javax.swing.*;

public class AverageExample
{
    private double[] marks;
    private JTextField[] marksField;
    private JLabel resultLabel;

    public AverageExample()
    {
        marks = new double[3];
        marksField = new JTextField[3];
        marksField[0] = new JTextField(10);
        marksField[1] = new JTextField(10);
        marksField[2] = new JTextField(10);
    }

    private void displayGUI()
    {
        int selection = JOptionPane.showConfirmDialog(
                null, getPanel(), "Input Form : "
                                , JOptionPane.OK_CANCEL_OPTION
                                , JOptionPane.PLAIN_MESSAGE);

        if (selection == JOptionPane.OK_OPTION) 
        {
            for ( int i = 0; i < 3; i++)
            {
                marks[i] = Double.valueOf(marksField[i].getText());             
            }
            Arrays.sort(marks);
            double average = (marks[1] + marks[2]) / 2.0;
            JOptionPane.showMessageDialog(null
                    , "Average is : " + Double.toString(average)
                    , "Average : "
                    , JOptionPane.PLAIN_MESSAGE);
        }
        else if (selection == JOptionPane.CANCEL_OPTION)
        {
            // Do something here.
        }
    }

    private JPanel getPanel()
    {
        JPanel basePanel = new JPanel();
        //basePanel.setLayout(new BorderLayout(5, 5));
        basePanel.setOpaque(true);
        basePanel.setBackground(Color.BLUE.darker());

        JPanel centerPanel = new JPanel();
        centerPanel.setLayout(new GridLayout(3, 2, 5, 5));
        centerPanel.setBorder(
            BorderFactory.createEmptyBorder(5, 5, 5, 5));
        centerPanel.setOpaque(true);
        centerPanel.setBackground(Color.WHITE);

        JLabel mLabel1 = new JLabel("Enter Marks 1 : ");
        JLabel mLabel2 = new JLabel("Enter Marks 2 : ");
        JLabel mLabel3 = new JLabel("Enter Marks 3 : ");

        centerPanel.add(mLabel1);
        centerPanel.add(marksField[0]);
        centerPanel.add(mLabel2);
        centerPanel.add(marksField[1]);
        centerPanel.add(mLabel3);
        centerPanel.add(marksField[2]);

        basePanel.add(centerPanel);

        return basePanel;
    }

    public static void main(String... args)
    {
        SwingUtilities.invokeLater(new Runnable()
        {
            @Override
            public void run()
            {
                new AverageExample().displayGUI();
            }
        });
    }
}

Try explicitly enumerating the results by calling ToList().

Change

foreach (var item in query)

to

foreach (var item in query.ToList())

value_counts is a Series method rather than a DataFrame method (and you are trying to use it on a DataFrame, clean). You need to perform this on a specific column:

clean[column_name].value_counts()

It doesn't usually make sense to perform value_counts on a DataFrame, though I suppose you could apply it to every entry by flattening the underlying values array:

pd.value_counts(df.values.flatten())

while(in.hasNextLine())  {
        lines++;
        String line = in.nextLine();
        for(int i=0;i<line.length();i++)
        {
            if(line.charAt(i)!=' ' && line.charAt(i)!='\n')
        chars ++;
        }
        words += new StringTokenizer(line, " ,;:.").countTokens();
    }

Don't write if statements without a corresponding else. Once you add the else to your fragment you'll see that your true and false are in fact the last expressions of the function.

def balanceMain(elem: List[Char]): Boolean =
  {
    if (elem.isEmpty)
      if (count == 0)
        true
      else
        false
    else
      if (elem.head == '(')
        balanceMain(elem.tail, open, count + 1)
      else....

This has caused me some confusion so I thought I'd share what I've come to learn the hard way:

When you request access using the access_type=offline and approval_prompt=force parameters you should receive both an access token and a refresh token. The access token expires soon after you receive it and you will need to refresh it.

You correctly made the request to get a new access token and received the response that has your new access token. I was also confused by the fact that I didn't get a new refresh token. However, this is how it is meant to be since you can use the same refresh token over and over again.

I think some of the other answers assume that you wanted to get yourself a new refresh token for some reason and sugggested that you re-authorize the user but in actual fact, you don't need to since the refresh token you have will work until revoked by the user.

In php:

• stripos() function is used to find the position of the first occurrence of a case-insensitive substring in a string.

• strripos() function is used to find the position of the last occurrence of a case-insensitive substring in a string.

Sample code:

$string = 'This is a string';
$substring ='i';
$firstIndex = stripos($string, $substring);
$lastIndex = strripos($string, $substring);

echo 'Fist index = ' . $firstIndex . ' ' . 'Last index = '. $lastIndex;

Output: Fist index = 2 Last index = 13

Technically, const is not part of the ECMAScript specification. Also, using the "CommonJS Module" pattern you've noted, you can change the value of that "constant" since it's now just an object property. (not sure if that'll cascade any changes to other scripts that require the same module, but it's possible)

To get a real constant that you can also share, check out Object.create, Object.defineProperty, and Object.defineProperties. If you set writable: false, then the value in your "constant" cannot be modified. :)

It's a little verbose, (but even that can be changed with a little JS) but you should only need to do it once for your module of constants. Using these methods, any attribute that you leave out defaults to false. (as opposed to defining properties via assignment, which defaults all the attributes to true)

So, hypothetically, you could just set value and enumerable, leaving out writable and configurable since they'll default to false, I've just included them for clarity.

Update - I've create a new module (node-constants) with helper functions for this very use-case.

constants.js -- Good

Object.defineProperty(exports, "PI", {
    value:        3.14,
    enumerable:   true,
    writable:     false,
    configurable: false
});

constants.js -- Better

function define(name, value) {
    Object.defineProperty(exports, name, {
        value:      value,
        enumerable: true
    });
}

define("PI", 3.14);

script.js

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

console.log(constants.PI); // 3.14
constants.PI = 5;
console.log(constants.PI); // still 3.14

This won't sum up the number; instead it will concatenate it:

var x = y + z;

You need to do:

var x = (y)+(z);

You must use parseInt in order to specify the operation on numbers. Example:

var x = parseInt(y) + parseInt(z); [final soulution, as everything us]

You need to change source to viewmodel object:

myBinding.Source = viewModelObject;

That is the textarea's job - for multiline text input. The input won't do it; it wasn't designed to do it.

So use a textarea. Besides their visual differences, they are accessed via JavaScript the same way (use value property).

You can prevent newlines being entered via the input event and simply using a replace(/\n/g, '').

Bandwidth is tiered by instance size, here's a comprehensive answer:

For t2/m3/c3/c4/r3/i2/d2 instances:

• t2.nano = ??? (Based on the scaling factors, I'd expect 20-30 MBit/s)
• t2.micro = ~70 MBit/s (qiita says 63 MBit/s) - t1.micro gets about ~100 Mbit/s
• t2.small = ~125 MBit/s (t2, qiita says 127 MBit/s, cloudharmony says 125 Mbit/s with spikes to 200+ Mbit/s)
• *.medium = t2.medium gets 250-300 MBit/s, m3.medium ~400 MBit/s
• *.large = ~450-600 MBit/s (the most variation, see below)
• *.xlarge = 700-900 MBit/s
• *.2xlarge = ~1 GBit/s +- 10%
• *.4xlarge = ~2 GBit/s +- 10%
• *.8xlarge and marked specialty = 10 Gbit, expect ~8.5 GBit/s, requires enhanced networking & VPC for full throughput

m1 small, medium, and large instances tend to perform higher than expected. c1.medium is another freak, at 800 MBit/s.

I gathered this by combing dozens of sources doing benchmarks (primarily using iPerf & TCP connections). Credit to CloudHarmony & flux7 in particular for many of the benchmarks (note that those two links go to google searches showing the numerous individual benchmarks).

Caveats & Notes:

The large instance size has the most variation reported:

• m1.large is ~800 Mbit/s (!!!)
• t2.large = ~500 MBit/s
• c3.large = ~500-570 Mbit/s (different results from different sources)
• c4.large = ~520 MBit/s (I've confirmed this independently, by the way)
• m3.large is better at ~700 MBit/s
• m4.large is ~445 Mbit/s
• r3.large is ~390 Mbit/s

Burstable (T2) instances appear to exhibit burstable networking performance too:

• The CloudHarmony iperf benchmarks show initial transfers start at 1 GBit/s and then gradually drop to the sustained levels above after a few minutes. PDF links to reports below:

• t2.small (PDF)

• t2.medium (PDF)
• t2.large (PDF)

Note that these are within the same region - if you're transferring across regions, real performance may be much slower. Even for the larger instances, I'm seeing numbers of a few hundred MBit/s.

1. Set the height of your label to the same height as the multiline textbox.

2. Add the cssClass .alignTop{vertical-align: middle;} for the label control.

   <p>
       <asp:Label ID="DescriptionLabel" runat="server" Text="Description: " Width="70px" Height="200px" CssClass="alignTop"></asp:Label>
       <asp:Textbox id="DescriptionTextbox" runat="server" Width="400px" Height="200px" TextMode="MultiLine"></asp:Textbox>

       ControlToValidate="DescriptionTextbox" ErrorMessage="Description is a required field.">    
   </asp:RequiredFieldValidator>
   

The only reason I'd worry about is that Dog is now allocated on the stack, rather than the heap. So if Dog is megabytes in size, you may have a problem,

If you do need to go the new/delete route, be wary of exceptions. And because of this you should use auto_ptr or one of the boost smart pointer types to manage the object lifetime.

Using pure javascript you can use Window.scrollX and Window.scrollY

window.addEventListener("scroll", function(event) {
    var top = this.scrollY,
        left =this.scrollX;
}, false);

Notes

The pageXOffset property is an alias for the scrollX property, and The pageYOffset property is an alias for the scrollY property:

window.pageXOffset == window.scrollX; // always true
window.pageYOffset == window.scrollY; // always true

Here is a quick demo

window.addEventListener("scroll", function(event) {_x000D_
  _x000D_
    var top = this.scrollY,_x000D_
        left = this.scrollX;_x000D_
  _x000D_
    var horizontalScroll = document.querySelector(".horizontalScroll"),_x000D_
        verticalScroll = document.querySelector(".verticalScroll");_x000D_
    _x000D_
    horizontalScroll.innerHTML = "Scroll X: " + left + "px";_x000D_
      verticalScroll.innerHTML = "Scroll Y: " + top + "px";_x000D_
  _x000D_

Simple: don't use an AsyncTask. AsyncTask is designed for short operations that end quickly (tens of seconds) and therefore do not need to be canceled. "Audio file playback" does not qualify. You don't even need a background thread for ordinary audio file playback.

Java heap size descriptions (xms, xmx, xmn)

-Xms size in bytes

Example : java -Xms32m

Sets the initial size of the Java heap. The default size is 2097152 (2MB). The values must be a multiple of, and greater than, 1024 bytes (1KB). (The -server flag increases the default size to 32M.)

-Xmn size in bytes

Example : java -Xmx2m

Sets the initial Java heap size for the Eden generation. The default value is 640K. (The -server flag increases the default size to 2M.)

-Xmx size in bytes

Example : java -Xmx2048m

Sets the maximum size to which the Java heap can grow. The default size is 64M. (The -server flag increases the default size to 128M.) The maximum heap limit is about 2 GB (2048MB).

Java memory arguments (xms, xmx, xmn) formatting

When setting the Java heap size, you should specify your memory argument using one of the letters “m” or “M” for MB, or “g” or “G” for GB. Your setting won’t work if you specify “MB” or “GB.” Valid arguments look like this:

-Xms64m or -Xms64M -Xmx1g or -Xmx1G Can also use 2048MB to specify 2GB Also, make sure you just use whole numbers when specifying your arguments. Using -Xmx512m is a valid option, but -Xmx0.5g will cause an error.

There is no correct answer, since it depends on what the definition of "syntax" is for your request. The most important thing is that you:

1. Use the response code(s) consistently
2. Include as much additional information in the response body as you can to help the developer(s) using your API figure out what's going on.=

Before everyone jumps all over me for saying that there is no right or wrong answer here, let me explain a bit about how I came to the conclusion.

In this specific example, the OP's question is about a JSON request that contains a different key than expected. Now, the key name received is very similar, from a natural language standpoint, to the expected key, but it is, strictly, different, and hence not (usually) recognized by a machine as being equivalent.

As I said above, the deciding factor is what is meant by syntax. If the request was sent with a Content Type of application/json, then yes, the request is syntactically valid because it's valid JSON syntax, but not semantically valid, since it doesn't match what's expected. (assuming a strict definition of what makes the request in question semantically valid or not).

If, on the other hand, the request was sent with a more specific custom Content Type like application/vnd.mycorp.mydatatype+json that, perhaps, specifies exactly what fields are expected, then I would say that the request could easily be syntactically invalid, hence the 400 response.

In the case in question, since the key was wrong, not the value, there was a syntax error if there was a specification for what valid keys are. If there was no specification for valid keys, or the error was with a value, then it would be a semantic error.
