As others have correctly pointed out, the first part of the ternary needs to return true or false and in your question the return value is a jQuery object.

The problem that you may have in the comparison is that the web color will be converted to RGB so you have to text for that in the ternary condition.

So with the CSS:

#blackbox {
    background:pink;
    width:10px;
    height:10px;
}

The following jQuery will flip the colour:

var b = $('#blackbox');
b.css('background', (b.css('backgroundColor') === 'rgb(255, 192, 203)' ? 'black' : 'pink'));

To use CSS3 Animation you must also define the actual animation keyframes (which you named spin)

Read https://developer.mozilla.org/en-US/docs/CSS/Tutorials/Using_CSS_animations for more info

Once you've configured the animation's timing, you need to define the appearance of the animation. This is done by establishing two or more keyframes using the @keyframes at-rule. Each keyframe describes how the animated element should render at a given time during the animation sequence.

Demo at http://jsfiddle.net/gaby/9Ryvs/7/

@-moz-keyframes spin {
    from { -moz-transform: rotate(0deg); }
    to { -moz-transform: rotate(360deg); }
}
@-webkit-keyframes spin {
    from { -webkit-transform: rotate(0deg); }
    to { -webkit-transform: rotate(360deg); }
}
@keyframes spin {
    from {transform:rotate(0deg);}
    to {transform:rotate(360deg);}
}

Robi Code is work for me, just put if !null so that if phone number is null, user can fill the phone number by him/her self.

editTextPhoneNumber = (EditText) findViewById(R.id.editTextPhoneNumber);
TelephonyManager tMgr;
tMgr= (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();
if (mPhoneNumber != null){
editTextPhoneNumber.setText(mPhoneNumber);
}

Dim strFirstAddress As String
Dim searchlast As Range
Dim search As Range

Set search = ActiveSheet.Range("A1:A100")
Set searchlast = search.Cells(search.Cells.Count)

Set rngFindValue = ActiveSheet.Range("A1:A100").Find(Text, searchlast, xlValues)
If Not rngFindValue Is Nothing Then
  strFirstAddress = rngFindValue.Address
  Do
    Set rngFindValue = search.FindNext(rngFindValue)
  Loop Until rngFindValue.Address = strFirstAddress

>>> d = {}
>>> D = set()
>>> type(d)
<type 'dict'>
>>> type(D)
<type 'set'>

What you've made is a dictionary and not a Set.

The update method in dictionary is used to update the new dictionary from a previous one, like so,

>>> abc = {1: 2}
>>> d.update(abc)
>>> d
{1: 2}

Whereas in sets, it is used to add elements to the set.

>>> D.update([1, 2])
>>> D
set([1, 2])

I have just made use of a reference to a pointer to make all the pointers in a deleted binary tree except the root safe. To make the pointer safe we just have to set it to 0. I could not make the function that deletes the tree (keeping only the root) to accept a ref to a pointer since I am using the root (this pointer) as the first input to traverse left and right.

void BinTree::safe_tree(BinTree * &vertex ) {
    if ( vertex!=0 ) {  // base case
        safe_tree(vertex->left);    // left subtree.
            safe_tree(vertex->right);   //  right subtree.
          // delete vertex;  // using this delete causes an error, since they were deleted on the fly using inorder_LVR. If inorder_LVR does not perform delete to the nodes, then, use delete vertex;
        vertex=0;  // making a safe pointer
    }
} // end in

Bottom line, a reference to a pointer is invalid when the formal parameter is the (this) pointer.

One can skip grep like this:

ls ~/Linux/Old/ -QI Tux.png | xargs -I{} mv ~/Linux/Old/{} ~/Linux/New/

adding to scotty's answer:

Option 1: Either include this in your JS file:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>

Option 2: or just use the URL to download 'angular-route.min.js' to your local.

and then (whatever option you choose) add this 'ngRoute' as dependency.

explained: var app = angular.module('myapp', ['ngRoute']);

You can use VBScript, for example, file myscript.vbs:

set wsobject = wscript.createobject("wscript.shell")

do while 1=1
    wsobject.run "SnippingTool.exe",0,TRUE
    wscript.sleep 3000
loop

Batch file:

cscript myscript.vbs %1

I typically free every allocated block once I'm sure that I'm done with it. Today, my program's entry point might be main(int argc, char *argv[]) , but tomorrow it might be foo_entry_point(char **args, struct foo *f) and typed as a function pointer.

So, if that happens, I now have a leak.

Regarding your second question, if my program took input like a=5, I would allocate space for a, or re-allocate the same space on a subsequent a="foo". This would remain allocated until:

1. The user typed 'unset a'
2. My cleanup function was entered, either servicing a signal or the user typed 'quit'

I can not think of any modern OS that does not reclaim memory after a process exits. Then again, free() is cheap, why not clean up? As others have said, tools like valgrind are great for spotting leaks that you really do need to worry about. Even though the blocks you example would be labeled as 'still reachable' , its just extra noise in the output when you're trying to ensure you have no leaks.

Another myth is "If its in main(), I don't have to free it", this is incorrect. Consider the following:

char *t;

for (i=0; i < 255; i++) {
    t = strdup(foo->name);
    let_strtok_eat_away_at(t);
}

If that came prior to forking / daemonizing (and in theory running forever), your program has just leaked an undetermined size of t 255 times.

A good, well written program should always clean up after itself. Free all memory, flush all files, close all descriptors, unlink all temporary files, etc. This cleanup function should be reached upon normal termination, or upon receiving various kinds of fatal signals, unless you want to leave some files laying around so you can detect a crash and resume.

Really, be kind to the poor soul who has to maintain your stuff when you move on to other things .. hand it to them 'valgrind clean' :)

Java IO using stream oriented APIs is performed using a buffer as temporary storage of data within user space. Data read from disk by DMA is first copied to buffers in kernel space, which is then transfer to buffer in user space. Hence there is overhead. Avoiding it can achieve considerable gain in performance.

We could skip this temporary buffer in user space, if there was a way directly to access the buffer in kernel space. Java NIO provides a way to do so.

ByteBuffer is among several buffers provided by Java NIO. Its just a container or holding tank to read data from or write data to. Above behavior is achieved by allocating a direct buffer using allocateDirect() API on Buffer.

Java Documentation of Byte Buffer has useful information.

Why does this error occur?

Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.

The first element in a collection is generally located at index 0. The last element is at index n-1, where n is the Size of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1, you're going to get an error.

How indexing arrays works

When you declare an array like this:

var array = new int[6]

The first and last elements in the array are

var firstElement = array[0];
var lastElement = array[5];

So when you write:

var element = array[5];

you are retrieving the sixth element in the array, not the fifth one.

Typically, you would loop over an array like this:

for (int index = 0; index < array.Length; index++)
{
    Console.WriteLine(array[index]);
}

This works, because the loop starts at zero, and ends at Length-1 because index is no longer less than Length.

This, however, will throw an exception:

for (int index = 0; index <= array.Length; index++)
{
    Console.WriteLine(array[index]);
}

Notice the <= there? index will now be out of range in the last loop iteration, because the loop thinks that Length is a valid index, but it is not.

How other collections work

Lists work the same way, except that you generally use Count instead of Length. They still start at zero, and end at Count - 1.

for (int index = 0; i < list.Count; index++)
{
    Console.WriteLine(list[index]);
} 

However, you can also iterate through a list using foreach, avoiding the whole problem of indexing entirely:

foreach (var element in list)
{
    Console.WriteLine(element.ToString());
}

You cannot index an element that hasn't been added to a collection yet.

var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]);  // Throws exception.

Docker for Mac solution

17.06 onwards

Thanks to @Birchlabs' comment, now it is tons easier with this special Mac-only DNS name available:

docker run -e DB_PORT=5432 -e DB_HOST=docker.for.mac.host.internal

From 17.12.0-cd-mac46, docker.for.mac.host.internal should be used instead of docker.for.mac.localhost. See release note for details.

Older version

@helmbert's answer well explains the issue. But Docker for Mac does not expose the bridge network, so I had to do this trick to workaround the limitation:

$ sudo ifconfig lo0 alias 10.200.10.1/24

Open /usr/local/var/postgres/pg_hba.conf and add this line:

host    all             all             10.200.10.1/24            trust

Open /usr/local/var/postgres/postgresql.conf and edit change listen_addresses:

listen_addresses = '*'

Reload service and launch your container:

$ PGDATA=/usr/local/var/postgres pg_ctl reload
$ docker run -e DB_PORT=5432 -e DB_HOST=10.200.10.1 my_app 

What this workaround does is basically same with @helmbert's answer, but uses an IP address that is attached to lo0 instead of docker0 network interface.

You can set progress bar's style to this:

style="@android:style/Widget.ProgressBar.Horizontal"    

They are often used interchangeably in text, but in most standards the distinction is that an argument is an expression passed to a function, where a parameter is a reference declared in a function declaration.

Type in

chmod 755 scriptname.sh

In other words, give yourself permission to run the file. I'm guessing you only have r/w permission on it.

You can get more info about your config files using something like:

$ -> php -i | ack config # Use fgrep -i if you don't have ack

Configure Command =>  './configure'  ...
Loaded Configuration File => /path/to/php.ini

You can use exit method to quit an ios app :

exit(0);

You should say same alert message and ask him to quit

Another way is by using [[NSThread mainThread] exit]

However you should not do this way

According to Apple, your app should not terminate on its own. Since the user did not hit the Home button, any return to the Home screen gives the user the impression that your app crashed. This is confusing, non-standard behavior and should be avoided.

Convert the image to a byte[] and store that in the database.

Add this column to your model:

public byte[] Content { get; set; }

Then convert your image to a byte array and store that like you would any other data:

public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
    using(var ms = new MemoryStream())
    {
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

        return ms.ToArray();
    }
}

public Image ByteArrayToImage(byte[] byteArrayIn)
{
     using(var ms = new MemoryStream(byteArrayIn))
     {
         var returnImage = Image.FromStream(ms);

         return returnImage;
     }
}

Source: Fastest way to convert Image to Byte array

var image = new ImageEntity()
{
   Content = ImageToByteArray(image)
};

_context.Images.Add(image);
_context.SaveChanges();

When you want to get the image back, get the byte array from the database and use the ByteArrayToImage and do what you wish with the Image

This stops working when the byte[] gets to big. It will work for files under 100Mb

I would go with xml and xpath:

dir C:\Projects\project_*\project*.config -recurse | foreach-object{  
   $wc = [xml](Get-Content $_.fullname)
   $wc.SelectNodes("//add[@key='Environment'][@value='Dev']") | Foreach-Object {$_.value = 'Demo'}  
   $wc.Save($_.fullname)  
}

The boost (tm) way:

std::string str = boost::lexical_cast<std::string>(dbl);

The Standard C++ way:

std::ostringstream strs;
strs << dbl;
std::string str = strs.str();

Note: Don't forget #include <sstream>

Just for the sake of people who landed here for the same reason I did:

Don't use reserved keywords

I named a function in my class definition delete(), which is a reserved keyword and should not be used as a function name. Renaming it to deletion() (which also made sense semantically in my case) resolved the issue.

For a list of reserved keywords: http://en.cppreference.com/w/cpp/keyword

I quote: "Since they are used by the language, these keywords are not available for re-definition or overloading. "

Your method is right, all you have to do is add a .0 after both the tens and it will fix your problem!

double example = Math.round((187/35) * 10.0) / 10.0;

The output would be:

5.3

Remove the class 'Carousal slide' on page load & add it dynamically when image gets loaded using jquery.This fixed for me

Just a side note for anyone that stumbles onto this same inquiry... My Operating System is 64 bit - so of course I downloaded the 64 bit MySQL driver... however, my Office applications are 32 bit... Once I downloaded the 32 bit version, the error went away and I could move forward.

Here's a different approach:

digits = sprintf(numArr, "%d", num);    // where numArr is a char array
if (num < 0)
    digits--;

This may not be efficient, just something different than what others suggested.

I worked with Yarn and I got the same issue and I solve it doing this:

rm -rf ^file/folder pattern to avoid

With extended_glob

setopt extended_glob
rm -- ^*.txt
rm -- ^*.(sql|txt)

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>

cduruk's solution was quite effective, but caused problems on a few parts of my site. Because I was already using jQuery to add the CSS hover class, the easiest solution was to simply not add the CSS hover class on mobile devices (or more precisely, to ONLY add it when NOT on a mobile device).

Here was the general idea:

var device = navigator.userAgent.toLowerCase();
var ios = device.match(/(iphone|ipod|ipad)/);

if (!(ios)) {
    $(".portfolio-style").hover(
        function(){
            $(this).stop().animate({opacity: 1}, 100);
            $(this).addClass("portfolio-red-text");
        },
        function(){
            $(this).stop().animate({opacity: 0.85}, 100);
            $(this).removeClass("portfolio-red-text");
        }
    );
}

If you are using Ubuntu many distros the notify-send command will throw one of those nice perishable notifications in the top right corner. Like so:

See here for an example from the OpenJPA docs. CascadeType.ALL means it will do all actions.

Quote:

CascadeType.PERSIST: When persisting an entity, also persist the entities held in its fields. We suggest a liberal application of this cascade rule, because if the EntityManager finds a field that references a new entity during the flush, and the field does not use CascadeType.PERSIST, it is an error.

CascadeType.REMOVE: When deleting an entity, it also deletes the entities held in this field.

CascadeType.REFRESH: When refreshing an entity, also refresh the entities held in this field.

CascadeType.MERGE: When merging entity state, also merge the entities held in this field.

I stumbled upon another possible reason of this error. If you use NTFS symbolic links in your project tree, and probably subst'ed drives, you may get this error even if they point to your local drive. If this is the case, try to avoid the situation when .resx files are reached via symlinks.

A small trick using sum with level=1(work when level=1 is all unique)

df.sum(level=1,axis=1)
Out[202]: 
   b  c
0  1  2
1  3  4

More common solution get_level_values

df.columns=df.columns.get_level_values(1)
df
Out[206]: 
   b  c
0  1  2
1  3  4

The correct syntax ( as tested in VS 2008 SP1), is this:

public static class ErrorCode
{
    public static IDictionary<string, string> ErrorCodeDic;
     static ErrorCode()
    {
        ErrorCodeDic = new Dictionary<string, string>()
            { {"1", "User name or password problem"} };
    }
}

I faced this problem where the following query doesn't work as expected:

select 1 where getdate()<>null

we expect it to show 1 because getdate() doesn't return null. I guess it has something to do with SQL failing to cast null as datetime and skipping the row! of course we know we should use IS or IS NOT keywords to compare a variable with null but when comparing two parameters it gets hard to handle the null situation. as a solution you can create your own compare function like the following:

CREATE FUNCTION [dbo].[fnCompareDates]
(
    @DateTime1 datetime,
    @DateTime2 datetime
)
RETURNS bit
AS
BEGIN
    if (@DateTime1 is null and @DateTime2 is null) return 1;
    if (@DateTime1 = @DateTime2) return 1;
    return 0
END

and re writing the query like:

select 1 where dbo.fnCompareDates(getdate(),null)=0

DECLARE @yourSpecialMark = '/';
select len(@yourString) - len(replace(@yourString,@yourSpecialMark,''))

It will count, how many times occours the special mark '/'

Well, if you have a number like 0.123456 that is the result of a division to give a percentage, multiply it by 100 and then either round it or use toFixed like in your example.

Math.round(0.123456 * 100) //12

Here is a jQuery plugin to do that:

jQuery.extend({
    percentage: function(a, b) {
        return Math.round((a / b) * 100);
    }
});

Usage:

alert($.percentage(6, 10));

Close Code 1006 is a special code that means the connection was closed abnormally (locally) by the browser implementation.

If your browser client reports close code 1006, then you should be looking at the websocket.onerror(evt) event for details.

However, Chrome will rarely report any close code 1006 reasons to the Javascript side. This is likely due to client security rules in the WebSocket spec to prevent abusing WebSocket. (such as using it to scan for open ports on a destination server, or for generating lots of connections for a denial-of-service attack).

Note that Chrome will often report a close code 1006 if there is an error during the HTTP Upgrade to Websocket (this is the step before a WebSocket is technically "connected"). For reasons such as bad authentication or authorization, or bad protocol use (such as requesting a subprotocol, but the server itself doesn't support that same subprotocol), or even an attempt at talking to a server location that isn't a WebSocket (such as attempting to connect to ws://images.google.com/)

Fundamentally, if you see a close code 1006, you have a very low level error with WebSocket itself (similar to "Unable to Open File" or "Socket Error"), not really meant for the user, as it points to a low level issue with your code and implementation. Fix your low level issues, and then when you are connected, you can then include more reasonable error codes. You can accomplish this in terms of scope or severity in your project. Example: info and warning level are part of your project's specific protocol, and don't cause the connection to terminate. With severe or fatal messages reporting also using your project's protocol to convey as much detail as you want, and then closing the connection using the limited abilities of the WebSocket close flow.

Be aware that WebSocket close codes are very strictly defined, and the close reason phrase/message cannot exceed 123 characters in length (this is an intentional WebSocket limitation).

But not all is lost, if you are just wanting this information for debugging reasons, the detail of the closure, and its underlying reason is often reported with a fair amount of detail in Chrome's Javascript console.

You need to subscribe to the observable and pass a callback that processes emitted values

this.myService.getConfig().subscribe(val => console.log(val));

<?php //-- Very simple variant
$useragent = $_SERVER['HTTP_USER_AGENT']; 
$iPod = stripos($useragent, "iPod"); 
$iPad = stripos($useragent, "iPad"); 
$iPhone = stripos($useragent, "iPhone");
$Android = stripos($useragent, "Android"); 
$iOS = stripos($useragent, "iOS");
//-- You can add billion devices 

$DEVICE = ($iPod||$iPad||$iPhone||$Android||$iOS||$webOS||$Blackberry||$IEMobile||$OperaMini);

if ($DEVICE !=true) {?>

<!-- What you want for all non-mobile devices. Anything with all HTML codes-->

<?php }else{ ?> 

<!-- What you want for all mobile devices. Anything with all HTML codes --> 
<?php } ?>

In the action you can call:

this.Request.PhysicalPath

that returns the physical path in reference to the current controller. If you only need the root path call:

this.Request.PhysicalApplicationPath

Server.MapPath specifies the relative or virtual path to map to a physical directory.

• Server.MapPath(".")¹ returns the current physical directory of the file (e.g. aspx) being executed
• Server.MapPath("..") returns the parent directory
• Server.MapPath("~") returns the physical path to the root of the application
• Server.MapPath("/") returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)

An example:

Let's say you pointed a web site application (http://www.example.com/) to

C:\Inetpub\wwwroot

and installed your shop application (sub web as virtual directory in IIS, marked as application) in

D:\WebApps\shop

For example, if you call Server.MapPath() in following request:

http://www.example.com/shop/products/GetProduct.aspx?id=2342

then:

• Server.MapPath(".")¹ returns D:\WebApps\shop\products
• Server.MapPath("..") returns D:\WebApps\shop
• Server.MapPath("~") returns D:\WebApps\shop
• Server.MapPath("/") returns C:\Inetpub\wwwroot
• Server.MapPath("/shop") returns D:\WebApps\shop

If Path starts with either a forward slash (/) or backward slash (\), the MapPath() returns a path as if Path was a full, virtual path.

If Path doesn't start with a slash, the MapPath() returns a path relative to the directory of the request being processed.

Note: in C#, @ is the verbatim literal string operator meaning that the string should be used "as is" and not be processed for escape sequences.

Footnotes

1. Server.MapPath(null) and Server.MapPath("") will produce this effect too.

Another example

public IEnumerable<string> Tokenize(params string[] words)
{
  ...
}

var items = Tokenize(product.Name, product.FullName, product.Xyz)

You can use distutils.dir_util.copy_tree. It works just fine and you don't have to pass every argument, only src and dst are mandatory.

However in your case you can't use a similar tool likeshutil.copytree because it behaves differently: as the destination directory must not exist this function can't be used for overwriting its contents.

If you want to use the cp tool as suggested in the question comments beware that using the subprocess module is currently the recommended way for spawning new processes as you can see in the documentation of the os.system function.

One option is to give the <a> a display of inline-block and then apply text-align: center; on the containing block (remove the float as well):

div { 
    background: red;
    overflow: hidden; 
    text-align: center;
}

span a {
    background: #222;
    color: #fff;

-O3 option turns on more expensive optimizations, such as function inlining, in addition to all the optimizations of the lower levels ‘-O2’ and ‘-O1’. The ‘-O3’ optimization level may increase the speed of the resulting executable, but can also increase its size. Under some circumstances where these optimizations are not favorable, this option might actually make a program slower.

Alternatively you can edit the source and create your own incrementations

check your build.gradle file and make sure that use apply plugin: 'com.android.application' istead of apply plugin: 'com.android.library'

it worked for me

You are testing against the string minus the last character:

>>> '"xxx"'[:-1]
'"xxx'

Note how the last character, the ", is not part of the output of the slice.

I think you wanted just to test against the last character; use [-1:] to slice for just the last element.

However, there is no need to slice here; just use str.startswith() and str.endswith() directly.

I would grab date.js or else you will need to roll your own formatting function.

tl;dr: No! Arrow functions and function declarations / expressions are not equivalent and cannot be replaced blindly.
If the function you want to replace does not use this, arguments and is not called with new, then yes.

As so often: it depends. Arrow functions have different behavior than function declarations / expressions, so let's have a look at the differences first:

1. Lexical this and arguments

Arrow functions don't have their own this or arguments binding. Instead, those identifiers are resolved in the lexical scope like any other variable. That means that inside an arrow function, this and arguments refer to the values of this and arguments in the environment the arrow function is defined in (i.e. "outside" the arrow function):

// Example using a function expression
function createObject() {
  console.log('Inside `createObject`:', this.foo);
  return {
    foo: 42,
    bar: function() {
      console.log('Inside `bar`:', this.foo);
    },
  };
}

createObject.call({foo: 21}).bar(); // override `this` inside createObject

// Example using a arrow function
function createObject() {
  console.log('Inside `createObject`:', this.foo);
  return {
    foo: 42,
    bar: () => console.log('Inside `bar`:', this.foo),
  };
}

createObject.call({foo: 21}).bar(); // override `this` inside createObject

In the function expression case, this refers to the object that was created inside the createObject. In the arrow function case, this refers to this of createObject itself.

This makes arrow functions useful if you need to access the this of the current environment:

// currently common pattern
var that = this;
getData(function(data) {
  that.data = data;
});

// better alternative with arrow functions
getData(data => {
  this.data = data;
});

Note that this also means that is not possible to set an arrow function's this with .bind or .call.

If you are not very familiar with this, consider reading

• MDN - this
• YDKJS - this & Object prototypes

2. Arrow functions cannot be called with new

ES2015 distinguishes between functions that are callable and functions that are constructable. If a function is constructable, it can be called with new, i.e. new User(). If a function is callable, it can be called without new (i.e. normal function call).

Functions created through function declarations / expressions are both constructable and callable.
Arrow functions (and methods) are only callable. class constructors are only constructable.

If you are trying to call a non-callable function or to construct a non-constructable function, you will get a runtime error.

Knowing this, we can state the following.

Replaceable:

• Functions that don't use this or arguments.
• Functions that are used with .bind(this)

Not replaceable:

• Constructor functions
• Function / methods added to a prototype (because they usually use this)
• Variadic functions (if they use arguments (see below))

Lets have a closer look at this using your examples:

Constructor function

This won't work because arrow functions cannot be called with new. Keep using a function declaration / expression or use class.

Prototype methods

Most likely not, because prototype methods usually use this to access the instance. If they don't use this, then you can replace it. However, if you primarily care for concise syntax, use class with its concise method syntax:

class User {
  constructor(name) {
    this.name = name;
  }
  
  getName() {
    return this.name;
  }
}

Object methods

Similarly for methods in an object literal. If the method wants to reference the object itself via this, keep using function expressions, or use the new method syntax:

const obj = {
  getName() {
    // ...
  },
};

Callbacks

It depends. You should definitely replace it if you are aliasing the outer this or are using .bind(this):

// old
setTimeout(function() {
  // ...
}.bind(this), 500);

// new
setTimeout(() => {
  // ...
}, 500);

But: If the code which calls the callback explicitly sets this to a specific value, as is often the case with event handlers, especially with jQuery, and the callback uses this (or arguments), you cannot use an arrow function!

Variadic functions

Since arrow functions don't have their own arguments, you cannot simply replace them with an arrow function. However, ES2015 introduces an alternative to using arguments: the rest parameter.

// old
function sum() {
  let args = [].slice.call(arguments);
  // ...
}

// new
const sum = (...args) => {
  // ...
};

If we are talking about inexpensive implementation of the skip-list, I wonder in term of big O, what the cost of this operation is:

YourType[] array = someSet.toArray(new YourType[yourSet.size()]);

I mean it is always get stuck into a whole array creation, so it is O(n):

PHPMailer uses Exceptions. Try to adopt the following code:

require_once '../class.phpmailer.php';

$mail = new PHPMailer(true); //defaults to using php "mail()"; the true param means it will throw exceptions on errors, which we need to catch

try {
  $mail->AddReplyTo('[email protected]', 'First Last');
  $mail->AddAddress('[email protected]', 'John Doe');
  $mail->SetFrom('[email protected]', 'First Last');
  $mail->AddReplyTo('[email protected]', 'First Last');
  $mail->Subject = 'PHPMailer Test Subject via mail(), advanced';
  $mail->AltBody = 'To view the message, please use an HTML compatible email viewer!'; // optional - MsgHTML will create an alternate automatically
  $mail->MsgHTML(file_get_contents('contents.html'));
  $mail->AddAttachment('images/phpmailer.gif');      // attachment
  $mail->AddAttachment('images/phpmailer_mini.gif'); // attachment
  $mail->Send();
  echo "Message Sent OK\n";
} catch (phpmailerException $e) {
  echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
  echo $e->getMessage(); //Boring error messages from anything else!
}

You will have to make a call to the YouTube data API's video resource after you make the search call. You can put up to 50 video IDs in a search, so you won't have to call it for each element.

https://developers.google.com/youtube/v3/docs/videos/list

You'll want to set part=contentDetails, because the duration is there.

For example, the following call:

https://www.googleapis.com/youtube/v3/videos?id=9bZkp7q19f0&part=contentDetails&key={YOUR_API_KEY}

Gives this result:

{
 "kind": "youtube#videoListResponse",
 "etag": "\"XlbeM5oNbUofJuiuGi6IkumnZR8/ny1S4th-ku477VARrY_U4tIqcTw\"",
 "items": [
  {

   "id": "9bZkp7q19f0",
   "kind": "youtube#video",
   "etag": "\"XlbeM5oNbUofJuiuGi6IkumnZR8/HN8ILnw-DBXyCcTsc7JG0z51BGg\"",
   "contentDetails": {
    "duration": "PT4M13S",
    "dimension": "2d",
    "definition": "hd",
    "caption": "false",
    "licensedContent": true,
    "regionRestriction": {
     "blocked": [
      "DE"
     ]
    }
   }
  }
 ]
}

The time is formatted as an ISO 8601 string. PT stands for Time Duration, 4M is 4 minutes, and 13S is 13 seconds.

Simply, create log4j.properties under src/main/assembly folder. Depending on if you want log messages to be shown in the console or in the file you modify your file. The following is going to show your messages in the console.

# Root logger option
log4j.rootLogger=INFO, stdout

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

I'll look at my docs; there's a way of specifying a configuration to change the path of the root web application away from ROOT (or ROOT.war), but it seems to have changed between Tomcat 5 and 6.

Found this:

http://www.nabble.com/Re:-Tomcat-6-and-ROOT-application...-td20017401.html

So, it seems that changing the root path (in ROOT.xml) is possible, but a bit broken -- you need to move your WAR outside of the auto-deployment directory. Mind if I ask why just renaming your file to ROOT.war isn't a workable solution?

db.getCollection('').find({}).sort({_id:-1}) 

This will sort your collection in descending order based on the date of insertion

If your detached HEAD is a fast forward of master and you just want the commits upstream, you can

git push origin HEAD:master

to push directly, or

git checkout master && git merge [ref of HEAD]

will merge it back into your local master.

Same exact problem after TimeMachine backup import. My solution was to stop the MySQL server and fix read-write permissions on the ib* files.

Since for me, some elements are created on page load, and some are dynamically added by the user; I used this to make sure everything stayed DRY.

On submit, find everything with class x, remove class x, add rule x.

$('#form').on('submit', function(e) {
    $('.alphanumeric_dash').each(function() {
        var $this = $(this);
        $this.removeClass('alphanumeric_dash');
        $(this).rules('add', {
            alphanumeric_dash: true
        });
    });
});

I found this thread among others and I agree it contains the most complete answers so I'm adding mine too:

1. sed and ed are so useful...by hand. Look at this code from @Johnny:

   sed -i -e 's/abc/XYZ/g' /tmp/file.txt
   

2. When my restriction is to use it in a shell script, no variable can be used inside in place of "abc" or "XYZ". The BashFAQ seems to agree with what I understand at least. So, I can't use:

   x='abc'
   y='XYZ'
   sed -i -e 's/$x/$y/g' /tmp/file.txt
   #or,
   sed -i -e "s/$x/$y/g" /tmp/file.txt
   

   but, what can we do? As, @Johnny said use a while read... but, unfortunately that's not the end of the story. The following worked well with me:

   #edit user's virtual domain
   result=
   #if nullglob is set then, unset it temporarily
   is_nullglob=$( shopt -s | egrep -i '*nullglob' )
   if [[ is_nullglob ]]; then
      shopt -u nullglob
   fi
   while IFS= read -r line; do
      line="${line//'<servername>'/$server}"
      line="${line//'<serveralias>'/$alias}"
      line="${line//'<user>'/$user}"
      line="${line//'<group>'/$group}"
      result="$result""$line"'\n'
   done < $tmp
   echo -e $result > $tmp
   #if nullglob was set then, re-enable it
   if [[ is_nullglob ]]; then
      shopt -s nullglob
   fi
   #move user's virtual domain to Apache 2 domain directory
   ......
   

3. As one can see if nullglob is set then, it behaves strangely when there is a string containing a * as in:

   <VirtualHost *:80>
    ServerName www.example.com
   

   which becomes

   <VirtualHost ServerName www.example.com
   

   there is no ending angle bracket and Apache2 can't even load.

4. This kind of parsing should be slower than one-hit search and replace but, as you already saw, there are four variables for four different search patterns working out of one parse cycle.

The most suitable solution I can think of with the given assumptions of the problem.

Maybe this is a bit redundant, but no one appeared to have mentioned this as a solution.

As a beginner in SQL I find that when using a BEGIN and END SSMS usually adds a squiggly line with incorrect syntax near 'END' to END, simply because there's no content in between yet. If you're just setting up BEGIN and END to get started and add the actual query later, then simply add a bogus PRINT statement so SSMS stops bothering you.

For example:

IF (1=1)
BEGIN
  PRINT 'BOGUS'
END

The following will indeed set you on the wrong track, thinking you made a syntax error which in this case just means you still need to add content in between BEGIN and END:

IF (1=1)
BEGIN
END

I had the same problem when I tried from inside Visual Studio and "git status" in shell showed no problem. But I managed to push the local changes with "git push" via shell.

If you don't have any index structures, you'll not get around the reading of the complete file. But you can optimize it by avoiding to read it line by line and use a regex to match all line terminators.

Sounds like you're expecting size_t to be the same as unsigned long (possibly 64 bits) when it's actually an unsigned int (32 bits). Try using %zu in both cases.

I'm not entirely certain though.

I think it's worth answering the generic question "R - test if string contains string" here.

For that, use the grep function.

# example:
> if(length(grep("ab","aacd"))>0) print("found") else print("Not found")
[1] "Not found"
> if(length(grep("ab","abcd"))>0) print("found") else print("Not found")
[1] "found"

This doesn't work for me. I've tried this both under Win7 64bit and Vista 32.

I'm using the below commandline to add this capability.

reg add "HKEY_CURRENT_USER\Software\Microsoft\Command Processor" /v AutoRun /t REG_SZ /d "IF x"%COMSPEC%"==x%CMDCMDLINE% (cd /D c:)"

Typing n will go to the next match.

This message displays when Internet Explorer reaches the maximum number of synchronous instructions for a piece of JavaScript. The default maximum is 5,000,000 instructions, you can increase this number on a single machine by editing the registry.

Internet Explorer now tracks the total number of executed script statements and resets the value each time that a new script execution is started, such as from a timeout or from an event handler, for the current page with the script engine. Internet Explorer displays a "long-running script" dialog box when that value is over a threshold amount.

The only way to solve the problem for all users that might be viewing your page is to break up the number of iterations your loop performs using timers, or refactor your code so that it doesn't need to process as many instructions.

Breaking up a loop with timers is relatively straightforward:

var i=0;
(function () {
    for (; i < 6000000; i++) {
        /*
            Normal processing here
        */

        // Every 100,000 iterations, take a break
        if ( i > 0 && i % 100000 == 0) {
            // Manually increment `i` because we break
            i++;
            // Set a timer for the next iteration 
            window.setTimeout(arguments.callee);
            break;
        }
    }
})();

I know this question is pretty old now, but I thought you might have an easier time with ElementTree

from xml.etree import ElementTree as ET
import datetime

f = ET.XML(data)

for element in f:
    if element.tag == "currentTime":
        # Handle time data was pulled
        currentTime = datetime.datetime.strptime(element.text, "%Y-%m-%d %H:%M:%S")
    if element.tag == "cachedUntil":
        # Handle time until next allowed update
        cachedUntil = datetime.datetime.strptime(element.text, "%Y-%m-%d %H:%M:%S")
    if element.tag == "result":
        # Process list of skills
        pass

I know that's not super specific, but I just discovered it, and so far it's a lot easier to get my head around than the minidom (since so many nodes are essentially white space).

For instance, you have the tag name and the actual text together, just as you'd probably expect:

>>> element[0]
<Element currentTime at 40984d0>
>>> element[0].tag
'currentTime'
>>> element[0].text
'2010-04-12 02:45:45'e

I see the question is about Express Edition, but this topic is easy to pop up in Google Search, and doesn't have a solution for other editions.

So. If you run into this problem with any VS Edition except Express, you can rerun installation and include MFC files.

jQuery is just a set of helpers/libraries written in Javascript. You can still use all Javascript features, so you can call whatever functions, also from inside jQuery callbacks. So both possibilities should be okay.

This way works:

class A
{
    struct Wrap
    {
        A& a;
        Wrap(A& aa) aa(a) {}
        operator int() { return a.value; }
        operator std::string() { stringstream ss; ss << a.value; return ss.str(); } 
    }
    Wrap operator*() { return Wrap(*this); }
};

I wrote a set of scripts that provides a uniform interface for both BSD and GNU version of date.

Follow command will output the Epoch seconds for the date 2010-10-02, and it works with both BSD and GNU version of date.

$ xsh /date/convert "2010-10-02" "+%s"
1286020263

It's an equivalent of the command with GNU version of date:

date -d "2010-10-02" "+%s"

and also the command with BSD version of date:

date -j -f "%F" 2010-10-02 "+%s"

The scripts can be found at:

• https://github.com/xsh-lib/core/tree/master/functions/date

It's a part of a library called xsh-lib/core. To use them you need both repos xsh and xsh-lib/core, I list them below:

• https://github.com/alexzhangs/xsh
• https://github.com/xsh-lib/core

Making something both a C identifier and a string

Try this way it will hide the calendar and show year only

$(function() {
    $( "#datepicker" ).datepicker({dateFormat: 'yy'});
    });?

CSS

.ui-datepicker-calendar {
   display: none;
}

DEMO ?

Keep a reference to the timer somewhere, and use:

timer.cancel();
timer.purge();

to stop whatever it's doing. You could put this code inside the task you're performing with a static int to count the number of times you've gone around, e.g.

private static int count = 0;
public static void run() {
     count++;
     if (count >= 6) {
         timer.cancel();
         timer.purge();
         return;
     }

     ... perform task here ....

}

for regular Joins, it doesn't. TableA join TableB will produce the same execution plan as TableB join TableA (so your C and D examples would be the same)

for left and right joins it does. TableA left Join TableB is different than TableB left Join TableA, BUT its the same than TableB right Join TableA

This solution worked for me:

tabBarOptions: {
      showIcon: true,
      showLabel: false,
      style: {
        backgroundColor: '#000',
        borderTopLeftRadius: 40,
        borderTopRightRadius: 40,
        position: 'relative',
        zIndex: 2,
        marginTop: -48
      }
  }

One final word on PSQL variables:

1. They don't expand if you enclose them in single quotes in the SQL statement. Thus this doesn't work:

   SELECT * FROM foo WHERE bar = ':myvariable'
   

2. To expand to a string literal in a SQL statement, you have to include the quotes in the variable set. However, the variable value already has to be enclosed in quotes, which means that you need a second set of quotes, and the inner set has to be escaped. Thus you need:

   \set myvariable '\'somestring\''  
   SELECT * FROM foo WHERE bar = :myvariable
   

   EDIT: starting with PostgreSQL 9.1, you may write instead:

   \set myvariable somestring
   SELECT * FROM foo WHERE bar = :'myvariable'
   

Strings are immutable objects so you can copy them just coping the reference to them, because the object referenced can't change ...

So you can copy as in your first example without any problem :

String s = "hello";
String backup_of_s = s;
s = "bye";

Though Excel format conditions will only display 1 of 3 conditions related to number size (they code it as "positive; negative; zero; text" but I prefer to see it as : if isnumber and true; elseif isnumber and false; elseif number; elseif is text )

so to me the best answer is David's as well as Grastveit's comment for other regional format.

Here are the ones I use depending on reports I make.

Take your pick!

I actually prefer EditRocket over TextMate. I use it on both my Mac and Ubuntu machines. It is nice to use the same editor on multiple operating systems.

{
int main(void);

should be

int main(void)
{

Then I let you fix the next compilation errors of your program...

alert('Alert For your User!') ? "" : location.reload();

You can write above code in this format also.It seems quite decent

Wanted to ADD to the other answers described here an additional note, in the case of custom exceptions.

In the case where you create your own custom exception, that derives from std::exception, when you catch "all possible" exceptions types, you should always start the catch clauses with the "most derived" exception type that may be caught. See the example (of what NOT to do):

#include <iostream>
#include <string>

using namespace std;

class MyException : public exception
{
public:

NOTE:

0) The proper order should be vice-versa, i.e.- first you catch (const MyException& e) which is followed by catch (const std::exception& e).

1) As you can see, when you run the program as is, the first catch clause will be executed (which is probably what you did NOT wanted in the first place).

2) Even though the type caught in the first catch clause is of type std::exception, the "proper" version of what() will be called - cause it is caught by reference (change at least the caught argument std::exception type to be by value - and you will experience the "object slicing" phenomena in action).

3) In case that the "some code due to the fact that XXX exception was thrown..." does important stuff WITH RESPECT to the exception type, there is misbehavior of your code here.

4) This is also relevant if the caught objects were "normal" object like: class Base{}; and class Derived : public Base {}...

5) g++ 7.3.0 on Ubuntu 18.04.1 produces a warning that indicates the mentioned issue:

In function ‘void illustrateDerivedExceptionCatch()’: item12Linux.cpp:48:2: warning: exception of type ‘MyException’ will be caught catch(const MyException& e) ^~~~~

item12Linux.cpp:43:2: warning: by earlier handler for ‘std::exception’ catch (const exception& e) ^~~~~

Again, I will say, that this answer is only to ADD to the other answers described here (I thought this point is worth mention, yet could not depict it within a comment).

This code will count frequency and remove duplicate elements:

from collections import Counter

str1='the cat sat on the hat hat'

int_list=str1.split();

unique_list = []
for el in int_list:

    if el not in unique_list:
        unique_list.append(el)
    else:
        print "Element already in the list"

print unique_list

c=Counter(int_list)

c.values()

c.keys()

Network communication Host -> Guest

Connect to the Guest and find out the ip address:

ifconfig 

example of result (ip address is 10.0.2.15):

eth0      Link encap:Ethernet  HWaddr 08:00:27:AE:36:99
          inet addr:10.0.2.15  Bcast:10.0.2.255  Mask:255.255.255.0

Go to Vbox instance window -> Menu -> Network adapters:

• adapter should be NAT
• click on "port forwarding"
• insert new record (+ icon)
  • for host ip enter 127.0.0.1, and for guest ip address you got from prev. step (in my case it is 10.0.2.15)
  • in your case port is 8000 - put it on both, but you can change host port if you prefer

Go to host system and try it in browser:

http://127.0.0.1:8000

or your network ip address (find out on the host machine by running: ipconfig).

Network communication Guest -> Host

In this case port forwarding is not needed, the communication goes over the LAN back to the host.

On the host machine - find out your netw ip address:

ipconfig

example of result:

IP Address. . . . . . . . . . . . : 192.168.5.1

On the guest machine you can communicate directly with the host, e.g. check it with ping:

# ping 192.168.5.1
PING 192.168.5.1 (192.168.5.1) 56(84) bytes of data.
64 bytes from 192.168.5.1: icmp_seq=1 ttl=128 time=2.30 ms
...

Firewall issues?

@Stranger suggested that in some cases it would be necessary to open used port (8000 or whichever is used) in firewall like this (example for ufw firewall, I haven't tested):

sudo ufw allow 8000 

Dont go crazy I just clean , then rebuild project and error was gone

It is a static initializer. It's executed when the class is loaded and a good place to put initialization of static variables.

From http://java.sun.com/docs/books/tutorial/java/javaOO/initial.html

A class can have any number of static initialization blocks, and they can appear anywhere in the class body. The runtime system guarantees that static initialization blocks are called in the order that they appear in the source code.

If you have a class with a static look-up map it could look like this

class MyClass {
    static Map<Double, String> labels;
    static {
        labels = new HashMap<Double, String>();
        labels.put(5.5, "five and a half");
        labels.put(7.1, "seven point 1");
    }
    //...
}

It's useful since the above static field could not have been initialized using labels = .... It needs to call the put-method somehow.

This error is also at times deceiving. It says file is not found even though the files is indeed present. It could be because of invalid unreadable special characters present in the files that could be caused by the editor you are using. This link might help you in such cases.

-bash: ./my_script: /bin/bash^M: bad interpreter: No such file or directory

The best way to find out if it is this issue is to simple place an echo statement in the entire file and verify if the same error is thrown.

/usr/local/ssl/openssl.cnf

is soft link of

/etc/ssl/openssl.cnf

You can see that using long list (ls -l) on the /usr/local/ssl/ directory where you will find

Use this code. Works fine for me. Share Something from Outside of an activity:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");

// Append Text
String Text = "Your Text Here"

intent.putExtra(Intent.EXTRA_TEXT, Text);

To prevent this dialog box from appearing, do the following:

1. Right click on the setup.exe for the Oracle 11g 32-bit client, and select Properties.
2. Select the Compatibility tab, and set the Compatibility mode to Windows 7. Click OK to close the Properties tab.
3. Double click setup.exe to install the client.

FileNotFound is just an unfortunate exception used to indicate that the web server returned a 404.

I would strongly recommend using SourceTree from Atlassian. (It's free.) It makes this trivial. You can stage individual hunks of code or individual lines of code quickly and easily.

I implemented some code to do it manually:

using System.Security.Principal;
public bool IsUserAdministrator()
{
    bool isAdmin;
    try
    {
        WindowsIdentity user = WindowsIdentity.GetCurrent();
        WindowsPrincipal principal = new WindowsPrincipal(user);
        isAdmin = principal.IsInRole(WindowsBuiltInRole.Administrator);
    }
    catch (UnauthorizedAccessException ex)
    {
        isAdmin = false;
    }
    catch (Exception ex)
    {
        isAdmin = false;
    }
    return isAdmin;
}

if you need to include the key of the document in the response, another alternative is:

async getMarker() {
    const snapshot = await firebase.firestore().collection('events').get()
    const documents = [];
    snapshot.forEach(doc => {
       documents[doc.id] = doc.data();
    });
    return documents;
}

export CFLAGS=-m32

The problem is that salesAmount is being set to a string. If you enter the variable in the python interpreter and hit enter, you'll see the value entered surrounded by quotes. For example, if you entered 56.95 you'd see:

>>> sales_amount = raw_input("[Insert sale amount]: ")
[Insert sale amount]: 56.95
>>> sales_amount
'56.95'

You'll want to convert the string into a float before multiplying it by sales tax. I'll leave that for you to figure out. Good luck!

This error means the application pool to which your deployed application belongs is not in Integrated mode.

I had the same problem. Everything works in VS2010 but when I run the same project in VS2008 I get the mentioned exception.

What I did in my VS2008 project to make it work was adding a call to the AddServiceEndpoint member of my ServiceHost object.

Here is my code snippet:

Uri baseAddress = new Uri("http://localhost:8195/v2/SystemCallbackListener");

ServiceHost host = new ServiceHost(typeof(SystemCallbackListenerImpl), baseAddress);

host.AddServiceEndpoint(typeof(CsfServiceReference.SystemCallbackListener),
                        new BasicHttpBinding(),
                        baseAddress);
host.Open();

I didn't modify the app.config file. But I guess the service endpoint could also have been added in the .config file.

You could do this:

InputStream in = new ByteArrayInputStream(string.getBytes("UTF-8"));

Note the UTF-8 encoding. You should specify the character set that you want the bytes encoded into. It's common to choose UTF-8 if you don't specifically need anything else. Otherwise if you select nothing you'll get the default encoding that can vary between systems. From the JavaDoc:

The behavior of this method when this string cannot be encoded in the default charset is unspecified. The CharsetEncoder class should be used when more control over the encoding process is required.

prefetch_related use for prefetch data for Many to many and many to one relationship data. select_related is to select data from a single value relationship. Both of these are used to fetch data from their relationships from a model. For example, you build a model and a model that has a relationship with other models. When a request comes you will also query for their relationship data and Django has very good mechanisms To access data from their relationship like book.author.name but when you iterate a list of models for fetching their relationship data Django create each request for every single relationship data. To overcome this we do have prefetchd_related and selected_related

$array[] = 'Hi';

pushes on top of the array.

$array['Hi'] = 'FooBar';

sets a specific index.

or you can simply have

$('.date-pick').datePicker().val(new Date()).trigger('change')

I faced the same problem. Initially I deleted the .bash_profile but this is not the right way. After installing anaconda it is showing the instructions clearly for this problem. Please check the image for solution provided by Anaconda

Run this command after opening cmd as administrator

net start mssqlserver /T902

This command is called trace flag 902. It is used to bypass script upgrade mode. Every time when you try to start your sql service it also looks for script upgrades. and when the script upgrade fail your service unable to start. So, Whenever we have such upgrade script failure issue and SQL is not getting started, we need to use trace flag 902 to start SQL.

I hope this will help you..

^{A sample command that exhibits the symptom: sed 's/./@/' <<<$'\xfc' fails, because byte 0xfc is not a valid UTF-8 char.
Note that, by contrast, GNU sed (Linux, but also installable on macOS) simply passes the invalid byte through, without reporting an error.}

Using the formerly accepted answer is an option if you don't mind losing support for your true locale (if you're on a US system and you never need to deal with foreign characters, that may be fine.)

However, the same effect can be had ad-hoc for a single command only:

LC_ALL=C sed -i "" 's|"iphoneos-cross","llvm-gcc:-O3|"iphoneos-cross","clang:-Os|g' Configure

Note: What matters is an effective LC_CTYPE setting of C, so LC_CTYPE=C sed ... would normally also work, but if LC_ALL happens to be set (to something other than C), it will override individual LC_*-category variables such as LC_CTYPE. Thus, the most robust approach is to set LC_ALL.

However, (effectively) setting LC_CTYPE to C treats strings as if each byte were its own character (no interpretation based on encoding rules is performed), with no regard for the - multibyte-on-demand - UTF-8 encoding that OS X employs by default, where foreign characters have multibyte encodings.

In a nutshell: setting LC_CTYPE to C causes the shell and utilities to only recognize basic English letters as letters (the ones in the 7-bit ASCII range), so that foreign chars. will not be treated as letters, causing, for instance, upper-/lowercase conversions to fail.

Again, this may be fine if you needn't match multibyte-encoded characters such as é, and simply want to pass such characters through.

If this is insufficient and/or you want to understand the cause of the original error (including determining what input bytes caused the problem) and perform encoding conversions on demand, read on below.

The problem is that the input file's encoding does not match the shell's.
More specifically, the input file contains characters encoded in a way that is not valid in UTF-8 (as @Klas Lindbäck stated in a comment) - that's what the sed error message is trying to say by invalid byte sequence.

Most likely, your input file uses a single-byte 8-bit encoding such as ISO-8859-1, frequently used to encode "Western European" languages.

Example:

The accented letter à has Unicode codepoint 0xE0 (224) - the same as in ISO-8859-1. However, due to the nature of UTF-8 encoding, this single codepoint is represented as 2 bytes - 0xC3 0xA0, whereas trying to pass the single byte 0xE0 is invalid under UTF-8.

Here's a demonstration of the problem using the string voilà encoded as ISO-8859-1, with the à represented as one byte (via an ANSI-C-quoted bash string ($'...') that uses \x{e0} to create the byte):

Note that the sed command is effectively a no-op that simply passes the input through, but we need it to provoke the error:

  # -> 'illegal byte sequence': byte 0xE0 is not a valid char.
sed 's/.*/&/' <<<$'voil\x{e0}'

To simply ignore the problem, the above LCTYPE=C approach can be used:

  # No error, bytes are passed through ('á' will render as '?', though).
LC_CTYPE=C sed 's/.*/&/' <<<$'voil\x{e0}'

If you want to determine which parts of the input cause the problem, try the following:

  # Convert bytes in the 8-bit range (high bit set) to hex. representation.
  # -> 'voil\x{e0}'
iconv -f ASCII --byte-subst='\x{%02x}' <<<$'voil\x{e0}'

The output will show you all bytes that have the high bit set (bytes that exceed the 7-bit ASCII range) in hexadecimal form. (Note, however, that that also includes correctly encoded UTF-8 multibyte sequences - a more sophisticated approach would be needed to specifically identify invalid-in-UTF-8 bytes.)

Performing encoding conversions on demand:

Standard utility iconv can be used to convert to (-t) and/or from (-f) encodings; iconv -l lists all supported ones.

Examples:

Convert FROM ISO-8859-1 to the encoding in effect in the shell (based on LC_CTYPE, which is UTF-8-based by default), building on the above example:

  # Converts to UTF-8; output renders correctly as 'voilà'
sed 's/.*/&/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')"

Note that this conversion allows you to properly match foreign characters:

  # Correctly matches 'à' and replaces it with 'ü': -> 'voilü'
sed 's/à/ü/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')"

To convert the input BACK to ISO-8859-1 after processing, simply pipe the result to another iconv command:

sed 's/à/ü/' <<<"$(iconv -f ISO-8859-1 <<<$'voil\x{e0}')" | iconv -t ISO-8859-1

There is a way to do this without explicitly setting your SHELL variable to point to bash. This can be useful if you have many makefiles since SHELL isn't inherited by subsequent makefiles or taken from the environment. You also need to be sure that anyone who compiles your code configures their system this way.

If you run sudo dpkg-reconfigure dash and answer 'no' to the prompt, your system will not use dash as the default shell. It will then point to bash (at least in Ubuntu). Note that using dash as your system shell is a bit more efficient though.

From the document of pandas,DataFrame structure can apply an operation (function) to itself .

DataFrame.apply(func, axis=0, broadcast=False, raw=False, reduce=None, args=(), **kwds)

Applies function along input axis of DataFrame. Objects passed to functions are Series objects having index either the DataFrame’s index (axis=0) or the columns (axis=1). Return type depends on whether passed function aggregates, or the reduce argument if the DataFrame is empty.

You can apply a custom function to operate the DataFrame .

This Helper evaluates the expression and if equals to the value it checks the radio button, and has the same parameters than RadioButtonFor (for this reason the name is diferent):

public static MvcHtmlString CheckedRadioButtonFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, object value)
{
    return CheckedRadioButtonFor(htmlHelper, expression, value, null);
}

public static MvcHtmlString CheckedRadioButtonFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, object value, object htmlAttributes)
{
    var func = expression.Compile();
    var attributes = new RouteValueDictionary(htmlAttributes);
    if ((object)func(htmlHelper.ViewData.Model) == value) {
        attributes["checked"] = "checked";
    }
    return htmlHelper.RadioButtonFor(expression, value, attributes);
}

Usage:

<%= Html.CheckedRadioButtonFor(m => m.Gender, "Male", new { id = "gender-male" })%>

Result:

<!-- For Model.Gender = "Male" -->
<input checked="checked" id="gender-male" name="Gender" type="radio" value="Male">
<!-- For Model.Gender = "Female" -->
<input id="gender-male" name="Gender" type="radio" value="Male">

You can do it setting the transparency via style right within the table tag:

<table id="Main table" style="background-color:rgba(0, 0, 0, 0);">

The last digit in the rgba function is for transparency. 1 means 100% opaque, while 0 stands for 100% transparent.

For me, nothing worked except the following, which solved the problem: open IIS, select the site, open Authentication (in the IIS section), right click Anonymous Authentication and select Edit, select Application Pool Identity.

At the most basic level, something of the form (function(){...})() is a function literal that is executed immediately. What this means is that you have defined a function and you are calling it immediately.

This form is useful for information hiding and encapsulation since anything you define inside that function remains local to that function and inaccessible from the outside world (unless you specifically expose it - usually via a returned object literal).

A variation of this basic form is what you see in jQuery plugins (or in this module pattern in general). Hence:

(function($) {
  ...
})(jQuery);

Which means you're passing in a reference to the actual jQuery object, but it's known as $ within the scope of the function literal.

Type 1 isn't really a plugin. You're simply assigning an object literal to jQuery.fn. Typically you assign a function to jQuery.fn as plugins are usually just functions.

Type 2 is similar to Type 1; you aren't really creating a plugin here. You're simply adding an object literal to jQuery.fn.

Type 3 is a plugin, but it's not the best or easiest way to create one.

To understand more about this, take a look at this similar question and answer. Also, this page goes into some detail about authoring plugins.

A string can be escaped comprehensively and compactly using JSON.stringify. It is part of JavaScript as of ECMAScript 5 and supported by major newer browser versions.

str = JSON.stringify(String(str));
str = str.substring(1, str.length-1);

Using this approach, also special chars as the null byte, unicode characters and line breaks \r and \n are escaped properly in a relatively compact statement.

In UTF-8:

1 byte:       0 -     7F     (ASCII)
2 bytes:     80 -    7FF     (all European plus some Middle Eastern)
3 bytes:    800 -   FFFF     (multilingual plane incl. the top 1792 and private-use)
4 bytes:  10000 - 10FFFF

In UTF-16:

2 bytes:      0 -   D7FF     (multilingual plane except the top 1792 and private-use )
4 bytes:   D800 - 10FFFF

In UTF-32:

4 bytes:      0 - 10FFFF

10FFFF is the last unicode codepoint by definition, and it's defined that way because it's UTF-16's technical limit.

It is also the largest codepoint UTF-8 can encode in 4 byte, but the idea behind UTF-8's encoding also works for 5 and 6 byte encodings to cover codepoints until 7FFFFFFF, ie. half of what UTF-32 can.

For Ubuntu Server 15.04 and 16.04 you need execute only this command

If you want to do this with XML not programmatically you can use on your TextView:

The answers that use pattern and a regex write the user's password into the input properties as plain text pattern='mypassword'. This will only be visible if developer tools are open but it still doesn't seem like a good idea.

Another issue with using pattern to check for a match is that you are likely to want to use pattern to check that the password is of the right form, e.g. mixed letters and numbers.

I also think these methods won't work well if the user switches between inputs.

Here's my solution which uses a bit more JavaScript but performs a simple equality check when either input is updated and then sets a custom HTML validity. Both inputs can still be tested for a pattern such as email format or password complexity.

For a real page you would change the input types to 'password'.

<form>
    <input type="text" id="password1" oninput="setPasswordConfirmValidity();">
    <input type="text" id="password2" oninput="setPasswordConfirmValidity();">
</form>
<script>
    function setPasswordConfirmValidity(str) {
        const password1 = document.getElementById('password1');
        const password2 = document.getElementById('password2');

        if (password1.value === password2.value) {
             password2.setCustomValidity('');
        } else {
            password2.setCustomValidity('Passwords must match');
        }
        console.log('password2 customError ', document.getElementById('password2').validity.customError);
        console.log('password2 validationMessage ', document.getElementById('password2').validationMessage);
    }
</script>

If you need to iterate a queue ... queue isn't the container you need.
Why did you pick a queue?
Why don't you take a container that you can iterate over?

1.if you pick a queue then you say you want to wrap a container into a 'queue' interface: - front - back - push - pop - ...

if you also want to iterate, a queue has an incorrect interface. A queue is an adaptor that provides a restricted subset of the original container

2.The definition of a queue is a FIFO and by definition a FIFO is not iterable

Sorry, but--in my opinion--RichieHindle is completely right about saying that method...

It's a function which is a member of a class.

Here is the example of a function that becomes the member of the class. Since then it behaves as a method of the class. Let's start with the empty class and the normal function with one argument:

>>> class C:
...     pass
...
>>> def func(self):
...     print 'func called'
...
>>> func('whatever')
func called

Now we add a member to the C class, which is the reference to the function. After that we can create the instance of the class and call its method as if it was defined inside the class:

>>> C.func = func
>>> o = C()
>>> o.func()
func called

We can use also the alternative way of calling the method:

>>> C.func(o)
func called

The o.func even manifests the same way as the class method:

>>> o.func
<bound method C.func of <__main__.C instance at 0x000000000229ACC8>>

And we can try the reversed approach. Let's define a class and steal its method as a function:

>>> class A:
...     def func(self):
...         print 'aaa'
...
>>> a = A()
>>> a.func
<bound method A.func of <__main__.A instance at 0x000000000229AD08>>
>>> a.func()
aaa

So far, it looks the same. Now the function stealing:

>>> afunc = A.func
>>> afunc(a)
aaa    

The truth is that the method does not accept 'whatever' argument:

>>> afunc('whatever')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unbound method func() must be called with A instance as first 
  argument (got str instance instead)

IMHO, this is not the argument against method is a function that is a member of a class.

Later found the Alex Martelli's answer that basically says the same. Sorry if you consider it duplication :)

I've been working on a project called GiySync. It still needs some work, but it's open source and I've been using it every day for a couple of years. I'm also working on a native OS X version I've called GitSyncApp

Right now it's OS X only but it should be easy to add support for Linux, and possibly Windows too.

It works by watching file system events and it uses to git to sync a project folder on your local machine and a server.

I tried the other solutions like osx fuse, Expand Drive, Transmit, several solutions that used rsync, etc. They all work 'OK' for small projects, but if you're working with a lot of code they did not work for me.

A lot of the file system options do caching to improve performance, which is fine, until it's not. Like if you're working with other people and someone else changes the files on the server.

I also ran into issues if I was on a flaky or slow network where I'd end up with empty files. Or file that didn't sync, then the caching got weird; hopefully you committed recently. Using git solves this problem because it checks each commit's integrity.

Two bonus features:

1. You end up with a commit for every save. It's not super useful but if you ever have to go back in time you can.
2. It works with any text editor.

This took me ages to figure out but could you try the same -

1 - Update and Upgrade

sudo apt-get update
sudo apt-get upgrade

2 - Purge MySQL Server and Client (if installed).

sudo apt-get purge mysql-server mysql-client

3 - Install MySQL Server and Client fresh

sudo apt-get install mysql-server mysql-client

4 - Test MySQL

mysql -u root -p
> enter root password

*** should get socket not found in /var/run/mysqld/mysql.sock

4 - Configure mysqld.cnf with nano of vi

sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf

Change bind-address from 127.0.0.1 to localhost

bind-address            = localhost

** Write and Exit

5 - Restart MySQL

sudo /etc/init.d/mysql restart

6 - check mysql

mysql -u root -p
> enter root password

Before Rails 2.x the preferred way to get the current environment was using the RAILS_ENV constant. Likewise, you can use RAILS_DEFAULT_LOGGER to get the current logger or RAILS_ROOT to get the path to the root folder.

Starting from Rails 2.x, Rails introduced the Rails module with some special methods:

• Rails.root
• Rails.env
• Rails.logger

This isn't just a cosmetic change. The Rails module offers capabilities not available using the standard constants such as StringInquirer support. There are also some slight differences. Rails.root doesn't return a simple String buth a Path instance.

Anyway, the preferred way is using the Rails module. Constants are deprecated in Rails 3 and will be removed in a future release, perhaps Rails 3.1.

Integer is only there for the sql standard ie deprecated by Oracle.

You should use Number instead.

Integers get stored as Number anyway by Oracle behind the scenes.

Most commonly when ints are stored for IDs and such they are defined with no params - so in theory you could look at the scale and precision columns of the metadata views to see of no decimal values can be stored - however 99% of the time this will not help.

As was commented above you could look for number(38,0) columns or similar (ie columns with no decimal points allowed) but this will only tell you which columns cannot take decimals, and not what columns were defined so that INTS can be stored.

Suggestion: do a data profile on the number columns. Something like this:

 select max( case when trunc(column_name,0)=column_name then 0 else 1 end ) as has_dec_vals
 from table_name

form comment of JStrahl format(as.Date(df$date),"%w"), we get number of current day : as.numeric(format(as.Date("2016-05-09"),"%w"))

SIGABRT means in general that there is an uncaught exception. There should be more information on the console.

Since TypeScript 3.7 was released you can use optional chaining now.

Property example:

let x = foo?.bar.baz();

This is equvalent to:

let x = (foo === null || foo === undefined) ?
    undefined :
    foo.bar.baz();

Moreover you can call:

Optional Call

function(otherFn: (par: string) => void) {
   otherFn?.("some value");
}

otherFn will be called only if otherFn won't be equal to null or undefined

Usage optional chaining in IF statement

This:

if (someObj && someObj.someProperty) {
    // ...
}

can be replaced now with this

if (someObj?.someProperty) {
    // ...
}

On spring boot 2 with webflux you need to define a ReactiveAuthenticationManager

You can use Collections.sort as follows:

private static void order(List<Person> persons) {

    Collections.sort(persons, new Comparator() {

        public int compare(Object o1, Object o2) {

            String x1 = ((Person) o1).getName();
            String x2 = ((Person) o2).getName();
            int sComp = x1.compareTo(x2);

            if (sComp != 0) {
               return sComp;
            } 

            Integer x1 = ((Person) o1).getAge();
            Integer x2 = ((Person) o2).getAge();
            return x1.compareTo(x2);
    }});
}

List<Persons> is now sorted by name, then by age.

String.compareTo "Compares two strings lexicographically" - from the docs.

Collections.sort is a static method in the native Collections library. It does the actual sorting, you just need to provide a Comparator which defines how two elements in your list should be compared: this is achieved by providing your own implementation of the compare method.

A better way in long run is to integrate Gradle in your project environment. Its a build tool for Java, and now being used a lot in the android development space.

You will need to make a .gradle file and list your library dependencies. Then, all you would need to do is import the project in IntelliJ using Gradle.

Cheers

Yes. The querystring is also encrypted with SSL. Nevertheless, as this article shows, it isn't a good idea to put sensitive information in the URL. For example:

URLs are stored in web server logs - typically the whole URL of each request is stored in a server log. This means that any sensitive data in the URL (e.g. a password) is being saved in clear text on the server

The easiest way is probably to use two parameters: One for hosts (can be an array), and one for vlan.

param([String[]] $Hosts, [String] $VLAN)

Instead of

foreach ($i in $args)

you can use

foreach ($hostName in $Hosts)

If there is only one host, the foreach loop will iterate only once. To pass multiple hosts to the script, pass it as an array:

myScript.ps1 -Hosts host1,host2,host3 -VLAN 2

...or something similar.

<div [hidden]="myExpression">

myExpression may be set to true or false

JSX is used with ReactJS as it is very similar to HTML and it gives programmers feel of using HTML whereas it ultimately transpiles to a javascript file.

Writing a for-loop and specifying function as {this.props.removeTaskFunction(todo)} will execute the functions whenever the loop is triggered .

To stop this behaviour we need to return the function to onClick.

The fat arrow function has a hidden return statement along with the bind property. Thus it returns the function to OnClick as Javascript can return functions too !!!!!

Use -

onClick={() => { this.props.removeTaskFunction(todo) }}

which means-

var onClick = function() {
  return this.props.removeTaskFunction(todo);
}.bind(this);

Use the translateY CSS property to vertically center your text in it's container

<style>
.centertext{

    position: relative;
    top: 50%;
    transform: translateY(40%);

}
</style>

And then apply it to your containing DIV

  <div class="centertext">
        <font style="color:white; font-size:20px;">   Your Text Here </font>
  </div>

Adjust the translateY percentage to suit your needs. Hope this helps

info is a pointer to a dictionary - you keep adding the same pointer to your list contact.

Insert info = {} into the loop and it should solve the problem:

...
content = []
for iframe in soup.find_all('iframe'):
    info = {}
    info['src'] = iframe.get('src')
    info['height'] = iframe.get('height')
    info['width'] = iframe.get('width')
...

I also tried deleting the database again, called update-database and then add-migration. I ended up with an additional migration that seems not to change anything (see below)

Based on above details, I think you have done last thing first. If you run Update database before Add-migration, it won't update the database with your migration schemas. First you need to add the migration and then run update command.

Try them in this order using package manager console.

PM> Enable-migrations //You don't need this as you have already done it
PM> Add-migration Give_it_a_name
PM> Update-database

I use:

> echo Aa | tr -d '\n' | xxd -p
4161

> echo 414161 | tr -d '\n' | xxd -r -p
AAa

The tr -d '\n' will trim any possible newlines in your input

following sequence of commands works (I lose the first line of the data -no header=None present-, but at least it loads):

df = pd.read_csv(filename, usecols=range(0, 42)) df.columns = ['YR', 'MO', 'DAY', 'HR', 'MIN', 'SEC', 'HUND', 'ERROR', 'RECTYPE', 'LANE', 'SPEED', 'CLASS', 'LENGTH', 'GVW', 'ESAL', 'W1', 'S1', 'W2', 'S2', 'W3', 'S3', 'W4', 'S4', 'W5', 'S5', 'W6', 'S6', 'W7', 'S7', 'W8', 'S8', 'W9', 'S9', 'W10', 'S10', 'W11', 'S11', 'W12', 'S12', 'W13', 'S13', 'W14']

Following does NOT work:

df = pd.read_csv(filename, names=['YR', 'MO', 'DAY', 'HR', 'MIN', 'SEC', 'HUND', 'ERROR', 'RECTYPE', 'LANE', 'SPEED', 'CLASS', 'LENGTH', 'GVW', 'ESAL', 'W1', 'S1', 'W2', 'S2', 'W3', 'S3', 'W4', 'S4', 'W5', 'S5', 'W6', 'S6', 'W7', 'S7', 'W8', 'S8', 'W9', 'S9', 'W10', 'S10', 'W11', 'S11', 'W12', 'S12', 'W13', 'S13', 'W14'], usecols=range(0, 42))

CParserError: Error tokenizing data. C error: Expected 53 fields in line 1605634, saw 54 Following does NOT work:

df = pd.read_csv(filename, header=None)

CParserError: Error tokenizing data. C error: Expected 53 fields in line 1605634, saw 54

Hence, in your problem you have to pass usecols=range(0, 2)

There is no direct string compare function in SQL Server

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

Notes

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

You're trying to convert a (rather rare) .flv file that (already) contains H.264 video and AAC audio.

Formatting your console's output as FFmpeg brings out these details.

 Input #0, flv, from 'video.flv':
   Duration: 00:05:01.20, start: 0.000000, bitrate: 66 kb/s
    Stream #0.0: Video: h264, yuv420p, 320x240 [PAR 1:1 DAR 4:3], 66 kb/s, 29.92 tbr, 1k tbn, 2k tbc 
    Stream #0.1: Audio: aac, 22050 Hz, stereo, s16

The original flv is converted to an .mp4 file with H.264 video and AAC audio (just like the original .flv):

Output #0, mp4, to 'video.mp4': 
    Stream #0.0: Video: mpeg4, yuv420p, 320x240 [PAR 1:1 DAR 4:3], q=2-31, 200 kb/s, 90k tbn, 29.92 tbc 
    Stream #0.1: Audio: 0x0000, 22050 Hz, stereo, s16, 64 kb/s

Because the audio and video data in the .flv are already in the format/codecs you need for the .mp4, you can just copy everything to the new .mp4 container. This process will be massively faster than decoding and reencoding everything:

ffmpeg -i video.flv -vcodec copy -acodec copy video.mp4

or more simply:

ffmpeg -i video.flv -codec copy video.mp4

The real error you're getting is:

Unsupported codec for output stream #0.1

Which means FFmpeg can't convert audio (stream #0.1) to AAC.

You can skip the error by:

• copying the audio data since it's already AAC encoded (use the copy command above)

or you can solve the error by:

• using a FFmpeg build with AAC decode/encode support. FFmpeg currently supports 4 AAC libraries (see FFmpeg and AAC Encoding Guide).

For more details you should also read Converting FLV to MP4 With FFmpeg The Ultimate Guide

This version builds on Robert Elliot's, but I'm not 100% sure of its efficacy.

// There are a few dependencies added by one of the Scala plugins that this cannot reach.
task downloadDependencies {
  description "Pre-downloads *most* dependencies"
  doLast {
    configurations.getAsMap().each { name, config ->
      println "Retrieving dependencies for $name"
      try {
        config.files
      } catch (e) {
        project.logger.info e.message // some cannot be resolved, silentlyish skip them
      }
    }
  }
}

I tried putting it into configuration instead of action (by removing doLast) and it broke zinc. I worked around it, but the end result was the same with or without. So, I left it as an explicit state. It seems to work enough to reduce the dependencies that have to be downloaded later, but not eliminate them in my case. I think one of the Scala plugins adds dependencies later.

You could always use "%p" in order to display 8 bit hex numbers.

int main (void)
{
    uint8_t a;
    uint32_t b;
    a=15;
    b=a<<28;
    printf("%p", b);
    return 0;
}

Output:

0xf0000000

If you want the latest file in the directory and you are using only the LastWriteTime to determine the latest file, you can do something like below:

gci path | sort LastWriteTime | select -last 1

On the other hand, if you want to only rely on the names that have the dates in them, you should be able to something similar

gci path | select -last 1

Also, if there are directories in the directory, you might want to add a ?{-not $_.PsIsContainer}

A bearer token is like a currency note e.g 100$ bill . One can use the currency note without being asked any/many questions.

Bearer Token A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).

with pandas, it is much easier, for example. assuming you have the following data as CSV and let's call it test.txt / test.csv (you know CSV is a sort of text file )

a,b,c,d
1,2,3,4
5,6,7,8

now using pandas

import pandas as pd
df = pd.read_csv("./text.txt")
df_to_doct = df.to_dict()

for each row, it would be

df.to_dict(orient='records')

and that's it.

DBNull.Value is what the .NET Database providers return to represent a null entry in the database. DBNull.Value is not null and comparissons to null for column values retrieved from a database row will not work, you should always compare to DBNull.Value.

I'm astonished that there isn't an activated signal and have the same problem. I solved it by making a subclass of QComboBox. I think it's better to avoid having to directly access the object and call its functions because that means more tight coupling and goes against Qt's philosophy. So here's the class I made that works for me.

class SmartComboBox : public QComboBox {

    Q_OBJECT

private slots:

    void triggerVariantActivated(int index);

public:

    SmartComboBox(QWidget *parent);

signals:

    void activated(const QVariant &);

};

And the implementation

void SmartComboBox::triggerVariantActivated(int index)
{
    activated(itemData(index));
}

SmartComboBox::SmartComboBox(QWidget *parent)
:QComboBox(parent)
{
    connect(this, SIGNAL(activated(int)), this, SLOT(triggerVariantActivated(int)));
}

You need to use a pointer or a reference as the proper type is not known at this time the compiler can not instantiate it.

Instead try:

void action(const typename Subclass::mytype &var) {
            (static_cast<Subclass*>(this))->do_action();
    }

1. Delete node_modules folder and package-lock.json file.

2. Then run following command it will update npm packages.

   npm update

3. Later start project executing following command.

   ng serve

Above steps worked for me.

You can use this function :

function SendByFTP {
    param (
        $userFTP = "anonymous",
        $passFTP = "anonymous",
        [Parameter(Mandatory=$True)]$serverFTP,
        [Parameter(Mandatory=$True)]$localFile,
        [Parameter(Mandatory=$True)]$remotePath
    )
    if(Test-Path $localFile){
        $remoteFile = $localFile.Split("\")[-1]
        $remotePath = Join-Path -Path $remotePath -ChildPath $remoteFile
        $ftpAddr = "ftp://${userFTP}:${passFTP}@${serverFTP}/$remotePath"
        $browser = New-Object System.Net.WebClient
        $url = New-Object System.Uri($ftpAddr)
        $browser.UploadFile($url, $localFile)    
    }
    else{
        Return "Unable to find $localFile"
    }
}

This function send specified file by FTP. You must call the function with these parameters :

• userFTP = "anonymous" by default or your username
• passFTP = "anonymous" by default or your password
• serverFTP = IP address of the FTP server
• localFile = File to send
• remotePath = the path on the FTP server

For example :

SendByFTP -userFTP "USERNAME" -passFTP "PASSWORD" -serverFTP "MYSERVER" -localFile "toto.zip" -remotePath "path/on/the/FTP/"

Understanding that you're probably talking about a local/desktop machine and would probably like to continue talking about a local/desktop machine, I'll throw an alternative out there for you just in case it might help you or someone else:

Set up multiple virtual server instances in the cloud, and share your code between them as a git repository (or mercurial, I suppose, though I have no personal experience all you really need is something decentralized). This has the benefit of giving you as close to a production experience as possible, and if you have experience setting up servers then it's not that complicated (or expensive, if you just want to spin a server up, do what you need to do, then spin it down again, then you're talking about a few cents up to say 50 cents, up to a few bucks if you just leave it running).

I do all of my project development in the cloud these days and I've found it much simpler to manage the infrastructure than I ever did when using local/non-virtualized installs, and it makes this sort of side-by-side scenario fairly straight forward. I just wanted to throw the idea out there if you hadn't considered it.

With css:

.img {
    display:table-cell;
    max-width:...px;
    max-height:...px;
    width:100%;
}

Using "kill -9 [PID]" or "killall -9 node" worked for me where "kill -2 [PID]" did not work.

If you're using IPython, you can simply run:

%load path/to/your/file.py

See http://ipython.org/ipython-doc/rel-1.1.0/interactive/tutorial.html

I ended up doing the following and it works:

return DatabaseContext.Applications
     .Include("Children.ChildRelationshipType");

Use TO_TIMESTAMP function

TO_TIMESTAMP(date_string,'YYYY-MM-DD HH24:MI:SS')

This might be a bit overkill, but I always use the the np.take function for any wrap-around indexing:

>>> a = np.array([1, 2, 3])
>>> np.take(a, range(0, len(a)+1), mode='wrap')
array([1, 2, 3, 1])

>>> np.take(a, range(-1, len(a)+1), mode='wrap')
array([3, 1, 2, 3, 1])

First, as already mentioned, try cleaning and rebuilding the project. If that does not work for you, try this:

Settings > Build, Execution, Deployment: Un-check Enable Instant Run to hot swap code...

This solved the problem right away for me.

P.S. I posted this answer since it's 2017 and I don't think this feature existed in 2014, so it wouldn't cause this problem.

If you want a navigation drawer, you should use fragments. I followed this tutorial last week and it works great:

http://developer.android.com/training/implementing-navigation/nav-drawer.html

You can also download sample code from this tutorial, to see how you can do this.

Without fragments:

This is your BaseActivity Code:

public class BaseActivity extends Activity
{
    public DrawerLayout drawerLayout;
    public ListView drawerList;
    public String[] layers;
    private ActionBarDrawerToggle drawerToggle;
    private Map map;

    protected void onCreate(Bundle savedInstanceState)
    {
        // R.id.drawer_layout should be in every activity with exactly the same id.
        drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

        drawerToggle = new ActionBarDrawerToggle((Activity) this, drawerLayout, R.drawable.ic_drawer, 0, 0) 
        {
            public void onDrawerClosed(View view) 
            {
                getActionBar().setTitle(R.string.app_name);
            }

            public void onDrawerOpened(View drawerView) 
            {
                getActionBar().setTitle(R.string.menu);
            }
        };
        drawerLayout.setDrawerListener(drawerToggle);

        getActionBar().setDisplayHomeAsUpEnabled(true);
        getActionBar().setHomeButtonEnabled(true);

        layers = getResources().getStringArray(R.array.layers_array);
        drawerList = (ListView) findViewById(R.id.left_drawer);
        View header = getLayoutInflater().inflate(R.layout.drawer_list_header, null);
        drawerList.addHeaderView(header, null, false);
        drawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, android.R.id.text1,
                layers));
        View footerView = ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(
                R.layout.drawer_list_footer, null, false);
        drawerList.addFooterView(footerView);

        drawerList.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int pos, long arg3) {
                map.drawerClickEvent(pos);
            }
        });
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        if (drawerToggle.onOptionsItemSelected(item)) {
            return true;
        }
        return super.onOptionsItemSelected(item);

    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        drawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        drawerToggle.onConfigurationChanged(newConfig);
    }
}

All the other Activities that needs to have a navigation drawer should extend this Activity instead of Activity itself, example:

public class AnyActivity extends BaseActivity
{
    //Because this activity extends BaseActivity it automatically has the navigation drawer
    //You can just write your normal Activity code and you don't need to add anything for the navigation drawer
}

XML

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <!-- The main content view -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
        <!-- Put what you want as your normal screen in here, you can also choose for a linear layout or any other layout, whatever you prefer -->
    </FrameLayout>
    <!-- The navigation drawer -->
    <ListView android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:background="#111"/>
</android.support.v4.widget.DrawerLayout>

Edit:

I experienced some difficulties myself, so here is a solution if you get NullPointerExceptions. In BaseActivity change the onCreate function to protected void onCreateDrawer(). The rest can stay the same. In the Activities which extend BaseActivity put the code in this order:

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity);
    super.onCreateDrawer();

This helped me fix my problem, hope it helps!

This is how you can create a navigation drawer with multiple activities, if you have any questions feel free to ask.

Edit 2:

As said by @GregDan your BaseActivity can also override setContentView() and call onCreateDrawer there:

@Override 
public void setContentView(@LayoutRes int layoutResID) 
{ 
    super.setContentView(layoutResID); 
    onCreateDrawer() ;
}

From what I know, it's highly recommended NOT to use the Finalizer / Destructor:

public ~MyClass() {
  //dont use this
}

Mostly, this is due to not knowing when or IF it will be called. The dispose method is much better, especially if you us using or dispose directly.

using is good. use it :)

Use greenlock-express: Free SSL, Automated HTTPS

Greenlock handles certificate issuance and renewal (via Let's Encrypt) and http => https redirection, out-of-the box.

express-app.js:

var express = require('express');
var app = express();

app.use('/', function (req, res) {
  res.send({ msg: "Hello, Encrypted World!" })
});

// DO NOT DO app.listen()
// Instead export your app:
module.exports = app;

server.js:

require('greenlock-express').create({
  // Let's Encrypt v2 is ACME draft 11
  version: 'draft-11'
, server: 'https://acme-v02.api.letsencrypt.org/directory'

  // You MUST change these to valid email and domains
, email: '[email protected]'
, approveDomains: [ 'example.com', 'www.example.com' ]
, agreeTos: true
, configDir: "/path/to/project/acme/"

, app: require('./express-app.j')

, communityMember: true // Get notified of important updates
, telemetry: true       // Contribute telemetry data to the project
}).listen(80, 443);

For Localhost

Just answering this ahead-of-time because it's a common follow-up question:

You can't have SSL certificates on localhost. However, you can use something like Telebit which will allow you to run local apps as real ones.

You can also use private domains with Greenlock via DNS-01 challenges, which is mentioned in the README along with various plugins which support it.

Non-standard Ports (i.e. no 80 / 443)

Read the note above about localhost - you can't use non-standard ports with Let's Encrypt either.

However, you can expose your internal non-standard ports as external standard ports via port-forward, sni-route, or use something like Telebit that does SNI-routing and port-forwarding / relaying for you.

You can also use DNS-01 challenges in which case you won't need to expose ports at all and you can also secure domains on private networks this way.

This is the trick I use. Good for responsive designs. Works perfectly when user tries to mess with browser resizing.

I think groupby should work.

df.groupby(['A', 'B']).max()['C']

If you need a dataframe back you can chain the reset index call.

df.groupby(['A', 'B']).max()['C'].reset_index()

In Python 2.6+, you could use io.open() that is default (builtin open()) on Python 3:

import io

with io.open(filename, 'w', encoding=character_encoding) as file:
    file.write(unicode_text)

It might be more convenient if you need to write the text incrementally (you don't need to call unicode_text.encode(character_encoding) multiple times). Unlike codecs module, io module has a proper universal newlines support.

Due to some problem my adb.exe, was lost. My space of work suffered an electrical energy interruption, after that, I could not run or compile android programs.

Adb.exe is a file which should be located in your [android directory]/sdk/platform-tools. In my case, the file dissapeared, however the platform-tools was ther. My solution was as follows:

• I changed the name directory of [android directory]/sdk/platform-tools towards platform-tools_OLD, in order to hide it for android studio without erase it.
• In [android directory]/sdk there is a file SDK Manager.exe, ... I launched it.
• A window of "Android SDK Manager" is shown, then, in the Tools folder I chose "Android SDK Platform Tools" and then, Install packages.
• Enter to Android Studio

This was well for me

I prefer to do it by using a BAT file.

With BAT file you have more control and can do whatever you want.

string batFileName = path + @"\" + Guid.NewGuid() + ".bat";

using (StreamWriter batFile = new StreamWriter(batFileName))
{
    batFile.WriteLine($"YOUR COMMAND");
    batFile.WriteLine($"YOUR COMMAND");
    batFile.WriteLine($"YOUR COMMAND");
}

ProcessStartInfo processStartInfo = new ProcessStartInfo("cmd.exe", "/c " + batFileName);
processStartInfo.UseShellExecute = true;
processStartInfo.CreateNoWindow = true;
processStartInfo.WindowStyle = ProcessWindowStyle.Normal;

Process p = new Process();
p.StartInfo = processStartInfo;
p.Start();
p.WaitForExit();

File.Delete(batFileName);

I experience the same thing and this is what I do.

First my installation of

pip install -r requirements.txt

is not on my active environment. So I did is activate my environment then run again the

pip install -r requirements.txt

You can achieve what you are trying to do, using a Stored Procedure which returns a query result. Views are not suitable / developed for operations like this one.

This error can be caused by unchecked Java version requirements.

In my case I was able to resolve this error, while building a high-profile open-source project, by switching from Java 9 to Java 8 using SDKMAN!.

sdk list java
sdk install java 8u152-zulu
sdk use java 8u152-zulu

Then doing a clean install as described below.

When using Maven as your build tool, it is sometimes helpful -- and usually gratifying, to do a clean 'install' build with testing disabled.

mvn clean install -DskipTests

Now that everything has been built and installed, you can go ahead and run the tests.

mvn test

You can also use the AddRange method

listBox1.Items.AddRange(myList.ToArray());

$('.sys').children('input[type=text], select').each(function () { ... });

EDIT: Actually this code above is equivalent to the children selector .sys > input[type=text] if you want the descendant select (.sys input[type=text]) you need to use the options given by @NiftyDude.

• jQuery.children()
• multiple selector
