If you are reencoding in your ffmpeg command line, that may be the reason why it is CPU intensive. You need to simply copy the streams to the single container. Since I do not have your command line I cannot suggest a specific improvement here. Your acodec and vcodec should be set to copy is all I can say.

EDIT: On seeing your command line and given you have already tried it, this is for the benefit of others who come across the same question. The command:

ffmpeg -i rtsp://@192.168.241.1:62156 -acodec copy -vcodec copy c:/abc.mp4

will not do transcoding and dump the file for you in an mp4. Of course this is assuming the streamed contents are compatible with an mp4 (which in all probability they are).

This also can happen if the device you are trying to run on has some older version of the provisioning profile you are using that points to an old, expired or revoked certificate or a certificate without associated private key. Delete any invalid Provisioning Profiles under your device section in Xcode organizer.

For me nothing have helped, I've ended up with a solution:

create /lib/systemd/system/mongod.service file with content

[Unit]
Description=High-performance, schema-free document-oriented database
After=network.target
Documentation=https://docs.mongodb.org/manual

[Service]
User=mongodb
Group=mongodb
ExecStart=/usr/bin/mongod --quiet --config /etc/mongod.conf

[Install]
WantedBy=multi-user.target

then start/stop commands should work

$ sudo service mongod start

For reference - I have Ubuntu 14.04 LTS, MongoDB 3.2.9 installed from

deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse

I got this error when Updating code first MVC5 database. Dropping (right click, delete) all the tables from my database and removing the migrations from the Migration folder worked for me.

Add the /usr/local/opt/python/libexec/bin explicitly to your .bash_profile:

export PATH="/usr/local/opt/python/libexec/bin:$PATH"

After that, it should work correctly.

A JavaScript function must first be made that holds what you want to be done:

function print() { console.log("Hello World!") }

and then that function must be called in the onClick method from inside an element:

<a onClick="print()"> ... </a>

You can learn more about modal interactions directly from the Bootstrap 3 documentation found here: http://getbootstrap.com/javascript/#modals

Your modal bind is also incorrect. It should be something like this, where "myModal" = ID of element:

$('#myModal').modal(options)

In other words, if you truly want to keep what you already have, put a "#" in front GSCCModal and see if that works.

It is also not very wise to have an onClick bound to a div element; something like a button would be more suitable.

Hope this helps!

Thanks to unutbu for the explanation. By default numpy.cov calculates the sample covariance. To obtain the population covariance you can specify normalisation by the total N samples like this:

Covariance = numpy.cov(a, b, bias=True)[0][1]
print(Covariance)

or like this:

Covariance = numpy.cov(a, b, ddof=0)[0][1]
print(Covariance)

The best way to achieve what you want is to create your own wpf based control , or use a one that was made by other people
why ? because there will be a noticeable performance impact when using the winforms dialog in a wpf application (for some reason)
i recommend this project
https://opendialog.codeplex.com/
or Nuget :

PM> Install-Package OpenDialog

it's very MVVM friendly and it isn't wraping the winforms dialog

Just saw the bug in one of my applications, as a catch-all, remember to enclose the name of all javascript properties that are the same as keyword.

Found this bug after attending to a bug where an object such as:

var x = { class: 'myClass', function: 'myFunction'};

generated the error (class and function are keywords) this was fixed by adding quotes

var x = { 'class': 'myClass', 'function': 'myFunction'};

I hope to save you some time

If you are using Docker you need to make sure ports are exposed as well

If you are connecting to multiple servers you should add a 'GO' before switching servers, or your sql statements will run against the wrong server.

e.g.

:CONNECT SERVER1
Select * from Table
GO
enter code here
:CONNECT SERVER1
Select * from Table
GO

The answers here are not actually completely correct. Close, but there's an edge case.

The difference is that $('body') actually selects the element by the tag name, whereas document.body references the direct object on the document.

That means if you (or a rogue script) overwrites the document.body element (shame!) $('body') will still work, but $(document.body) will not. So by definition they're not equivalent.

I'd venture to guess there are other edge cases (such as globally id'ed elements in IE) that would also trigger what amounts to an overwritten body element on the document object, and the same situation would apply.

Just use in the CSS whatever you would use in a fill attribute. Of course, this requires that you have defined the linear gradient somewhere in your SVG.

Here is a complete example:

rect {_x000D_
    cursor: pointer;_x000D_
    shape-rendering: crispEdges;_x000D_
    fill: url(#MyGradient);_x000D_
}

<svg width="100" height="50" version="1.1" xmlns="http://www.w3.org/2000/svg">_x000D_
      <style type="text/css">_x000D_
        rect{fill:url(#MyGradient)}_x000D_
      </style>_x000D_
      <defs>_x000D_
        <linearGradient id="MyGradient">_x000D_
          <stop offset="5%" stop-color="#F60" />_x000D_
          <stop offset="95%" stop-color="#FF6" />_x000D_
        </linearGradient>_x000D_
      </defs>_x000D_
      _x000D_
      <rect width="100" height="50"/>_x000D_
    </svg>

I used

diff -rqyl folder1 folder2 --exclude=node_modules

in my nodejs apps.

The Left join in this query is pointless:

UPDATE md SET md.status = '3' 
FROM pd_mounting_details AS md 
LEFT OUTER JOIN pd_order_ecolid AS oe ON md.order_data = oe.id

It would update all rows of pd_mounting_details, whether or not a matching row exists in pd_order_ecolid. If you wanted to only update matching rows, it should be an inner join.

If you want to apply some condition based on the join occurring or not, you need to add a WHERE clause and/or a CASE expression in your SET clause.

Q1) Here are couple things to read or google more :

Main differences between SOAP and RESTful web services in java http://www.ajaxonomy.com/2008/xml/web-services-part-1-soap-vs-rest

It's up to you what do you want to learn first. I'd recommend you take a look at the CXF framework. You can build both rest/soap services.

Q2) Here are couple of good tutorials for soap (I had them bookmarked) :

http://united-coders.com/phillip-steffensen/developing-a-simple-soap-webservice-using-spring-301-and-apache-cxf-226

http://www.benmccann.com/blog/web-services-tutorial-with-apache-cxf/

http://www.mastertheboss.com/web-interfaces/337-apache-cxf-interceptors.html

Best way to learn is not just reading tutorials. But you would first go trough tutorials to get a basic idea so you can see that you're able to produce something(or not) and that would get you motivated.

SO is great way to learn particular technology (or more), people ask lot of wierd questions, and there are ever weirder answers. But overall you'll learn about ways to solve issues on other way. Maybe you didn't know of that way, maybe you couldn't thought of it by yourself.

Subscribe to couple of tags that are interesting to you and be persistent, ask good questions and try to give good answers and I guarantee you that you'll learn this as time passes (if you're persistent that is).

Q3) You will have to answer this one yourself. First by deciding what you're going to build, after all you will need to think of some mini project or something and take it from there.

If you decide to use CXF as your framework for building either REST/SOAP services I'd recommend you look up this book Apache CXF Web Service Development. It's fantastic, not hard to read and not too big either (win win).

You can also fix this problem by adding to model (Entity Framework version >= 5)

[DatabaseGenerated(DatabaseGeneratedOption.Computed)]
public DateTime CreationDate { get; set; }

You can use output parameters with sp_executesql.

DECLARE @dbName nvarchar(128) = 'myDb'
DECLARE @siteId int 
DECLARE @SQL nvarchar(max) = N'SELECT TOP 1 @siteId = Id FROM ' + quotename(@dbName) + N'..myTbl'
exec sp_executesql @SQL, N'@siteId int out', @siteId out
select @siteId

You ca try this:

ul { list-style: none;}

li { position: relative;}

li:before {
    position: absolute;  
    top: 8px;  
    margin: 8px 0 0 -12px;    
    vertical-align: middle;
    display: inline-block;
    width: 4px;
    height: 4px;
    background: #ccc;
    content: "";
}

It worked for me, thanks to this post.

To run the batch file when the VM user logs in:

Drag the shortcut--the one that's currently on your desktop--(or the batch file itself) to Start - All Programs - Startup. Now when you login as that user, it will launch the batch file.

Another way to do the same thing is to save the shortcut or the batch file in %AppData%\Microsoft\Windows\Start Menu\Programs\Startup\.

As far as getting it to run full screen, it depends a bit what you mean. You can have it launch maximized by editing your batch file like this:

start "" /max "C:\Program Files\Oracle\VirtualBox\VirtualBox.exe" --comment "VM" --startvm "12dada4d-9cfd-4aa7-8353-20b4e455b3fa"

But if VirtualBox has a truly full-screen mode (where it hides even the taskbar), you'll have to look for a command-line parameter on VirtualBox.exe. I'm not familiar with that product.

Check if scp is installed or not on from where you want want to copy check using which scp

If it's already installed, it will print you a path like /usr/bin/scp Else, install scp using:

yum -y install openssh-clients

Then copy command

Hovercraft Full Of Eels' answer is very good, but i had to change it a bit in order to get it working on my program:

int y1 = (int) ((this.height - 2 * BORDER_GAP) - (values.get(i) * yScale - BORDER_GAP));

instead of

int y1 = (int) (scores.get(i) * yScale + BORDER_GAP);

because if i used his way the graphic would be upside down

(you'd see it if you used hardcoded values (e.g 1,3,5,7,9) instead of random values)

You have to know the structure of your page, because if your canvas is a child of a div which in turn is a child of another div... then the story gets more complicated. Here's my code for a canvas which is inside 2 levels of div s:

canvas.addEventListener("click", function(event) {
var x = event.pageX - (this.offsetLeft + this.parentElement.offsetLeft);
var y = event.pageY - (this.offsetTop + this.parentElement.offsetTop);
console.log("relative x=" + x, "relative y" + y);

});

This works for me when aligning image view in linearlayout.

With iOS 7 system default font, you'll be using helvetica neue bold if you are looking to keep system default font.

    [titleText setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:16.0]];

Or you can simply call it:

    [titleText setFont:[UIFont boldSystemFontOfSize:16.0]];

Try this.

import java.sql.Connection;

import java.sql.DriverManager;

     Connection conn = DriverManager.getConnection(db_connect_string,
              db_userid, db_password);
     System.out.println("connected");
     Statement statement = conn.createStatement();
     String queryString = "select * from cpl";
     ResultSet rs = statement.executeQuery(queryString);
     while (rs.next()) {
        System.out.println(rs.getString(1));
     }
  } catch (Exception e) {
     e.printStackTrace();
  }    }

public static void main(String[] args) {

There is a sample from google, which lists the existing google accounts and generates an access token upon selection , you can send that access token to server to retrieve the related details from it to identify the user.

You can also get the email id from access token , for that you need to modify the SCOPE

Please go through My Post

<?php $data = array('a'=>'apple','b'=>'banana','c'=>'orange');?>
<pre><?php print_r($data); ?></pre>

Result:
Array
(
          [a] => apple
          [b] => banana
          [c] => orange
)

Or you can use this function:

DELIMITER $$

CREATE FUNCTION BLOB2TXT (blobfield VARCHAR(255)) RETURNS longtext
DETERMINISTIC

BEGIN
       RETURN CAST(blobfield AS CHAR(10000) CHARACTER SET utf8);
END
$$


DELIMITER ;

By default, IE displays webpages in the Intranet zone in compatibility view. To change this:

• Press Alt to display the IE menu.
• Choose Tools | Compatibility View settings
• Remove the checkmark next to Display intranet sites in Compatibility View.
• Choose Close.

At this point, IE should rely on the webpage itself (or any relevant group policies) to determine the compatibility settings for your Intranet webpages.

Note that certain sites may no longer function correctly after making this change. You can use the same dialog box to add specific sites to enable compatibility view when needed.

If you look at the docs for bytes, it points you to bytearray:

bytearray([source[, encoding[, errors]]])

Return a new array of bytes. The bytearray type is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that the bytes type has, see Bytes and Byte Array Methods.

The optional source parameter can be used to initialize the array in a few different ways:

If it is a string, you must also give the encoding (and optionally, errors) parameters; bytearray() then converts the string to bytes using str.encode().

If it is an integer, the array will have that size and will be initialized with null bytes.

If it is an object conforming to the buffer interface, a read-only buffer of the object will be used to initialize the bytes array.

If it is an iterable, it must be an iterable of integers in the range 0 <= x < 256, which are used as the initial contents of the array.

Without an argument, an array of size 0 is created.

So bytes can do much more than just encode a string. It's Pythonic that it would allow you to call the constructor with any type of source parameter that makes sense.

For encoding a string, I think that some_string.encode(encoding) is more Pythonic than using the constructor, because it is the most self documenting -- "take this string and encode it with this encoding" is clearer than bytes(some_string, encoding) -- there is no explicit verb when you use the constructor.

Edit: I checked the Python source. If you pass a unicode string to bytes using CPython, it calls PyUnicode_AsEncodedString, which is the implementation of encode; so you're just skipping a level of indirection if you call encode yourself.

Also, see Serdalis' comment -- unicode_string.encode(encoding) is also more Pythonic because its inverse is byte_string.decode(encoding) and symmetry is nice.

I think I got there in the end.

The task is like this:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default({}) | combine( {item.item.name: item.stdout} ) }}"
  with_items: "{{ people.results }}"

It loops through each of the dicts (item) in the people.results array, each time creating a new dict like {Bob: "male"}, and combine()s that new dict in the genders array, which ends up like:

{
    "Bob": "male",
    "Thelma": "female"
}

It assumes the keys (the name in this case) will be unique.

I then realised I actually wanted a list of dictionaries, as it seems much easier to loop through using with_items:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default([]) + [ {'name': item.item.name, 'gender': item.stdout} ] }}"
  with_items: "{{ people.results }}"

This keeps combining the existing list with a list containing a single dict. We end up with a genders array like this:

[
    {'name': 'Bob', 'gender': 'male'},
    {'name': 'Thelma', 'gender': 'female'}
]

Right click on the file with file explorer, choose Properties, then General tab and click on the Unblock button. This error message is very misleading.

Really fast, really easy:

srand(time(NULL)); // Seed the time
int finalNum = rand()%(max-min+1)+min; // Generate the number, assign to variable.

And that is it. However, this is biased towards the lower end, but if you are using C++ TR1/C++11 you can do it using the random header to avoid that bias like so:

#include <random>

std::mt19937 rng(seed);
std::uniform_int_distribution<int> gen(min, max); // uniform, unbiased

int r = gen(rng);

But you can also remove the bias in normal C++ like this:

int rangeRandomAlg2 (int min, int max){
    int n = max - min + 1;
    int remainder = RAND_MAX % n;
    int x;
    do{
        x = rand();
    }while (x >= RAND_MAX - remainder);
    return min + x % n;
}

and that was gotten from this post.

If you're using the IE developer tools, make sure you haven't accidentally left them at an older setting. I was making myself crazy with this same issue until I saw that it was set to Internet Explorer 7 Standards. Changed it to Internet Explorer 9 Standards and everything snapped right into place.

The check has to be like this:

if num == line.split()[0]:

If file.txt has a layout like this:

1 foo
20 bar
30 20

We split up "1 foo" into ['1', 'foo'] and just use the first item, which is the number.

In my case, my server was configured to work only in https mode, and error occured when I try to access http mode. So changing http://my-service to https://my-service helped.

If the response code isn't 200 or 2xx, use getErrorStream() instead of getInputStream().

There is no need to kill entire session. In Oracle 18c you could use ALTER SYSTEM CANCEL:

Cancelling a SQL Statement in a Session

You can cancel a SQL statement in a session using the ALTER SYSTEM CANCEL SQL statement.

Instead of terminating a session, you can cancel a high-load SQL statement in a session. When you cancel a DML statement, the statement is rolled back.

ALTER SYSTEM CANCEL SQL 'SID, SERIAL[, @INST_ID][, SQL_ID]';

If @INST_ID is not specified, the instance ID of the current session is used.

If SQL_ID is not specified, the currently running SQL statement in the specified session is terminated.

MDN suggests that there's a much cleaner way of doing this in modern browsers:

// Assuming we're listening for e.g. a 'change' event on `element`

// Create a new 'change' event
var event = new Event('change');

// Dispatch it.
element.dispatchEvent(event);

if you recently added multidex support in android studio like this:

// To Support MultiDex
implementation 'com.android.support:multidex:1.0.1'

so your solution is just extend From MultiDexApplication instead of Application

public class MyApp extends MultiDexApplication {

Try this:

REGEXP '^[a-z0-9]+$'

As regexp is not case sensitive except for binary fields.

You can use while(in.available() != 0) instead of while(true).

Prototype 1.7.1 way

function get_element_registry(element) {
    var cache = Event.cache;
    if(element === window) return 0;
    if(typeof element._prototypeUID === 'undefined') {
        element._prototypeUID = Element.Storage.UID++;
    }
    var uid =  element._prototypeUID;           
    if(!cache[uid]) cache[uid] = {element: element};
    return cache[uid];
}

I also faced the same issue...try to do this...this worked for me

        .scrollBbar 
        {
        position:fixed;
        top:50px;
        bottom:0;
        left:0;
        width:200px;
        overflow-x:hidden;
        overflow-y:auto;
       }

Easy peasy:

var date = DateTime.Parse("14/11/2011"); // may need some Culture help here
Console.Write(date.ToString("yyyy-MM-dd"));

Take a look at DateTime.ToString() method, Custom Date and Time Format Strings and Standard Date and Time Format Strings

string customFormattedDateTimeString = DateTime.Now.ToString("yyyy-MM-dd");

You can wrap them in a div and give the div a set width (the width of the widest image + margin maybe?) and then float the divs. Then, set the images to the center of their containing divs. Your margins between images won't be consistent for the differently sized images but it'll lay out much more nicely on the page.

This is what you need:

 =NOT(ISERROR(MATCH(<cell in col A>,<column B>, 0)))  ## pseudo code

For the first cell of A, this would be:

 =NOT(ISERROR(MATCH(A2,$B$2:$B$5, 0)))

Enter formula (and drag down) as follows:

You will get:

function _modulename_getData($field, $table) {
  try {
    if (empty($field)) {
      throw new Exception("The field is undefined."); 
    }
    // rest of code here...
  }
  catch (Exception $e) {
    /*
        Here you can either echo the exception message like: 
        echo $e->getMessage(); 

        Or you can throw the Exception Object $e like:
        throw $e;
    */
  }
}

Simplest way is to use dimensions in % or em. Just change the base font size everything will change.

Less

@media (max-width: @screen-xs) {
    body{font-size: 10px;}
}

@media (max-width: @screen-sm) {
    body{font-size: 14px;}
}


h5{
    font-size: 1.4rem;
}

// Since `slice` is available on an array's prototype chain,
'slice' in []; //-> true
[].slice === Array.prototype.slice; //-> true

// … we can just invoke it directly:
[].slice(); //-> []

// `arguments` has no `slice` method
'slice' in arguments; //-> false

// … but we can apply it the same way:
Array.prototype.slice.call(arguments); //-> […]

// In fact, though `slice` belongs to `Array.prototype`,
// it can operate on any array-like object:
Array.prototype.slice.call({0: 1, length: 1}); //-> [1]

Assign a int -1 to an unsigned: As -1 does not fit in the range [0...UINT_MAX], multiples of UINT_MAX+1 are added until the answer is in range. Evidently UINT_MAX is pow(2,32)-1 or 429496725 on OP's machine so a has the value of 4294967295.

    unsigned int a = -1;

The "%x", "%u" specifier expects a matching unsigned. Since these do not match, "If a conversion specification is invalid, the behavior is undefined. If any argument is not the correct type for the corresponding conversion specification, the behavior is undefined." C11 §7.21.6.1 9. The printf specifier does not change b.

    printf("%x\n", b);  // UB
    printf("%u\n", b);  // UB

The "%d" specifier expects a matching int. Since these do not match, more UB.

    printf("%d\n", a);  // UB

Given undefined behavior, the conclusions are not supported.

both cases, the bytes are the same (ffffffff).

Even with the same bit pattern, different types may have different values. ffffffff as an unsigned has the value of 4294967295. As an int, depending signed integer encoding, it has the value of -1, -2147483647 or TBD. As a float it may be a NAN.

what is unsigned word for?

unsigned stores a whole number in the range [0 ... UINT_MAX]. It never has a negative value. If code needs a non-negative number, use unsigned. If code needs a counting number that may be +, - or 0, use int.

Update: to avoid a compiler warning about assigning a signed int to unsigned, use the below. This is an unsigned 1u being negated - which is well defined as above. The effect is the same as a -1, but conveys to the compiler direct intentions.

unsigned int a = -1u;

Adding to Winnie's great answer,

If anyone is not able to find the postgresql.conf file location in your setup, you can always ask the postgres itself.

SHOW config_file;

For me changing the max_connections alone made the trick.

Use the ListView.ItemContainerStyle property to give your ListViewItems an EventSetter that will handle the PreviewMouseLeftButtonDown event. Then, in the handler, check to see if the item that was clicked is selected.

XAML:

<ListView ItemsSource={Binding MyItems}>
    <ListView.View>
        <GridView>
            <!-- declare a GridViewColumn for each property -->
        </GridView>
    </ListView.View>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <EventSetter Event="PreviewMouseLeftButtonDown" Handler="ListViewItem_PreviewMouseLeftButtonDown" />
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

Code-behind:

private void ListViewItem_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
    var item = sender as ListViewItem;
    if (item != null && item.IsSelected)
    {
        //Do your stuff
    }
}

A lot of people hear adviced to use List and i prefer to use it as well

here are two methods you need to sort the entries of the Map according to their values.

    static final Comparator<Entry<?, Double>> DOUBLE_VALUE_COMPARATOR = 
        new Comparator<Entry<?, Double>>() {
            @Override
            public int compare(Entry<?, Double> o1, Entry<?, Double> o2) {
                return o1.getValue().compareTo(o2.getValue());
            }
        };

        static final List<Entry<?, Double>> sortHashMapByDoubleValue(HashMap temp)
        {
            Set<Entry<?, Double>> entryOfMap = temp.entrySet();

            List<Entry<?, Double>> entries = new ArrayList<Entry<?, Double>>(entryOfMap);
            Collections.sort(entries, DOUBLE_VALUE_COMPARATOR);
            return entries;
        }

Java doesn't have the concept of optional parameters with default values either in constructors or in methods. You're basically stuck with overloading. However, you chain constructors easily so you don't need to repeat the code:

public Foo(int param1, int param2)
{
    this.param1 = param1;
    this.param2 = param2;
}

public Foo(int param1)
{
    this(param1, 2);
}

Your dialog should not be a "long-lived object that needs a context". The documentation is confusing. Basically if you do something like:

static Dialog sDialog;

(note the static)

Then in an activity somewhere you did

 sDialog = new Dialog(this);

You would likely be leaking the original activity during a rotation or similar that would destroy the activity. (Unless you clean up in onDestroy, but in that case you probably wouldn't make the Dialog object static)

For some data structures it would make sense to make them static and based off the application's context, but generally not for UI related things, like dialogs. So something like this:

Dialog mDialog;

...

mDialog = new Dialog(this);

Is fine and shouldn't leak the activity as mDialog would be freed with the activity since it's not static.

jQuery to check for checked? Really?

if(!this.checked) {

Don't use a bazooka to do a razor's job.

ES2015 and later

In ES2015, parameter destructuring can be used to simulate named parameters. It would require the caller to pass an object, but you can avoid all of the checks inside the function if you also use default parameters:

myFunction({ param1 : 70, param2 : 175});

function myFunction({param1, param2}={}){
  // ...function body...
}

// Or with defaults, 
function myFunc({
  name = 'Default user',
  age = 'N/A'
}={}) {
  // ...function body...
}

ES5

There is a way to come close to what you want, but it is based on the output of Function.prototype.toString ^[ES5], which is implementation dependent to some degree, so it might not be cross-browser compatible.

The idea is to parse the parameter names from the string representation of the function so that you can associate the properties of an object with the corresponding parameter.

A function call could then look like

func(a, b, {someArg: ..., someOtherArg: ...});

where a and b are positional arguments and the last argument is an object with named arguments.

For example:

var parameterfy = (function() {
    var pattern = /function[^(]*\(([^)]*)\)/;

    return function(func) {
        // fails horribly for parameterless functions ;)
        var args = func.toString().match(pattern)[1].split(/,\s*/);

        return function() {
            var named_params = arguments[arguments.length - 1];
            if (typeof named_params === 'object') {
                var params = [].slice.call(arguments, 0, -1);
                if (params.length < args.length) {
                    for (var i = params.length, l = args.length; i < l; i++) {
                        params.push(named_params[args[i]]);
                    }
                    return func.apply(this, params);
                }
            }
            return func.apply(null, arguments);
        };
    };
}());

Which you would use as:

var foo = parameterfy(function(a, b, c) {
    console.log('a is ' + a, ' | b is ' + b, ' | c is ' + c);     
});

foo(1, 2, 3); // a is 1  | b is 2  | c is 3
foo(1, {b:2, c:3}); // a is 1  | b is 2  | c is 3
foo(1, {c:3}); // a is 1  | b is undefined  | c is 3
foo({a: 1, c:3}); // a is 1  | b is undefined  | c is 3 

DEMO

There are some drawbacks to this approach (you have been warned!):

• If the last argument is an object, it is treated as a "named argument objects"
• You will always get as many arguments as you defined in the function, but some of them might have the value undefined (that's different from having no value at all). That means you cannot use arguments.length to test how many arguments have been passed.

Instead of having a function creating the wrapper, you could also have a function which accepts a function and various values as arguments, such as

call(func, a, b, {posArg: ... });

or even extend Function.prototype so that you could do:

foo.execute(a, b, {posArg: ...});

With the help of the of Guido mail provided by @kindall, we can understand the standard import process as trying to find the module in each member of sys.path, and file as the result of this lookup (more details in PyMOTW Modules and Imports.). So if the module is located in an absolute path in sys.path the result is absolute, but if it is located in a relative path in sys.path the result is relative.

Now the site.py startup file takes care of delivering only absolute path in sys.path, except the initial '', so if you don't change it by other means than setting the PYTHONPATH (whose path are also made absolute, before prefixing sys.path), you will get always an absolute path, but when the module is accessed through the current directory.

Now if you trick sys.path in a funny way you can get anything.

As example if you have a sample module foo.py in /tmp/ with the code:

import sys
print(sys.path)
print (__file__)

If you go in /tmp you get:

>>> import foo
['', '/tmp', '/usr/lib/python3.3', ...]
./foo.py

When in in /home/user, if you add /tmp your PYTHONPATH you get:

>>> import foo
['', '/tmp', '/usr/lib/python3.3', ...]
/tmp/foo.py

Even if you add ../../tmp, it will be normalized and the result is the same.

But if instead of using PYTHONPATH you use directly some funny path you get a result as funny as the cause.

>>> import sys
>>> sys.path.append('../../tmp')
>>> import foo
['', '/usr/lib/python3.3', .... , '../../tmp']
../../tmp/foo.py

Guido explains in the above cited thread, why python do not try to transform all entries in absolute paths:

we don't want to have to call getpwd() on every import .... getpwd() is relatively slow and can sometimes fail outright,

So your path is used as it is.

function myFunction() {
    console.log('It works!');
}

var name = 'myFunction';

window[name].call();

Invoking of validation on form element could be handled by triggering change event on this element:

a) exemple: trigger change on separated element in form

$scope.formName.elementName.$$element.change();

b) exemple: trigger change event for each of form elements for example on ng-submit, ng-click, ng-blur ...

vm.triggerChangeForFormElements = function() {
    // trigger change event for each of form elements
    angular.forEach($scope.formName, function (element, name) {
        if (!name.startsWith('$')) {
            element.$$element.change();
        }
    });
};

c) and one more way for that

    var handdleChange = function(form){
        var formFields = angular.element(form)[0].$$controls;
        angular.forEach(formFields, function(field){
            field.$$element.change();
        });
    };

It appears you no longer need toggleButton.setTextOff(textOff); and toggleButton.setTextOn(textOn);. The text for each toggled state will change by merely including the relevant xml characteristics. This will override the default ON/OFF text.

<ToggleButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/toggleText"
    android:textOff="ADD TEXT"
    android:textOn="CLOSE TEXT"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="10dp"
    android:visibility="gone"/>

@klode's answer is right.

However, you are supposed to set another response header to make your header accessible to others.

Example:

First, you add 'page-size' in response header

response.set('page-size', 20);

Then, all you need to do is expose your header

response.set('Access-Control-Expose-Headers', 'page-size')

Run it through a fairly simple regex: [^a-zA-Z]

And then check it's length separately:

if(string.Length > 7)

import java.util.SortedSet;
import java.util.TreeSet;

import javax.swing.JOptionPane;
import javax.swing.JFrame;

public class Average {

    public static void main(String [] args) {

        String test1= JOptionPane.showInputDialog("Please input mark for test 1: ");

        String test2= JOptionPane.showInputDialog("Please input mark for test 2: ");

        String test3= JOptionPane.showInputDialog("Please input mark for test 3: ");

        int int1 = Integer.parseInt(test1);
        int int2 = Integer.parseInt(test2);
        int int3 = Integer.parseInt(test3);

        SortedSet<Integer> set = new TreeSet<>();
        set.add(int1);
        set.add(int2);
        set.add(int3);

        Integer [] intArray = set.toArray(new Integer[3]);
        JFrame frame = new JFrame();
        JOptionPane.showInternalMessageDialog(frame.getContentPane(), String.format("Result %f", (intArray[1] + intArray[2]) / 2.0));

    }

}

Escape it. The pipe symbol is one that has been handled differently over time and between browsers. For instance, Chrome and Firefox convert a URL with pipe differently when copy/paste them. However, the most compatible, and necessary with Tomcat 8.5 it seems, is to escape it:

http://localhost:8080/app/handleResponse?msg=name%7Cid%7C

Maybe an interesting point to make, is the difference between priorities between both.

As far as I can tell, the ng-if directive has one of the highest (if not the highest) priority of all Angular directives. Which means: it will run FIRST before all other, lower prioritised, directives. The fact that it runs FIRST, means that effectively, the element is removed before any inner directives are processed. Or at least: that's what I make of it.

I observerd and used this in the UI I'm building for my current customer. The entire UI is quite heavily packed, and it had ng-show and ng-hide all over it. Not to go into too much detail, but I built a generic component, which could be managed using JSON config, so I had to do some switching inside the template. There is an ng-repeat present, and inside the ng-repeat, a table is shown, which has a lot of ng-shows, ng-hides and even ng-switches present. They wanted to show at least 50 repeats in the list, which would result in more or less 1500-2000 directives to be resolved. I checked the code, and the Java backend + custom JS on the front would take about 150ms to process the data, and then Angular would chew some 2-3 seconds on it, before displaying. The customer did not complain, but I was appalled :-)

In my search, I stumbled across the ng-if directive. Now, maybe it's best to point out that at the point of conceiving this UI, there was no ng-if available. Because the ng-show and ng-hide had functions in them, which returned booleans, I could easily replace them all with ng-if. By doing so, all inner directives seemed to be no longer evaluated. That meant that I dropped back to about a third of all directives being evaluated, and thus, the UI speeded up to about 500ms - 1 sec loading time. (I have no way to determine exact seconds)

Do note: the fact that the directives are not evaluated, is an educated guess about what is happening underneath.

So, in my opinion: if you need the element to be present on the page (ie: for checking the element, or whatever), but simply be hidden, use ng-show/ng-hide. In all other cases, use ng-if.

This worked for me. Thank you Rody!

y="HELLO"
val=$(echo $y | tr '[:upper:]' '[:lower:]')
string="$val world"

one small modification, if you are using underscore next to the variable You need to encapsulate the variable name in {}.

string="${val}_world"

You may also try the following in order to get the entire first entry,

Map.Entry<String, String> entry = map.entrySet().stream().findFirst().get();
String key = entry.getKey();
String value = entry.getValue();

The following shows how you may get the key of the first entry,

String key = map.entrySet().stream().map(Map.Entry::getKey).findFirst().get();
// or better
String key = map.keySet().stream().findFirst().get();

The following shows how you may get the value of the first entry,

String value = map.entrySet().stream().map(Map.Entry::getValue).findFirst().get();
// or better
String value = map.values().stream().findFirst().get();

Moreover, in case wish to get the second (same for third etc) item of a map and you have validated that this map contains at least 2 entries, you may use the following.

Map.Entry<String, String> entry = map.entrySet().stream().skip(1).findFirst().get();
String key = map.keySet().stream().skip(1).findFirst().get();
String value = map.values().stream().skip(1).findFirst().get();

You'll want something like this:

$("#next").click(function(){
      var currentElement = currentElement.next();
      $('html, body').animate({scrollLeft: $(currentElement).offset().left}, 800);
      return false;
   }); 

These regexes are equivalent (for matching purposes):

• /^(7|8|9)\d{9}$/
• /^[789]\d{9}$/
• /^[7-9]\d{9}$/

The explanation:

• (a|b|c) is a regex "OR" and means "a or b or c", although the presence of brackets, necessary for the OR, also captures the digit. To be strictly equivalent, you would code (?:7|8|9) to make it a non capturing group.

• [abc] is a "character class" that means "any character from a,b or c" (a character class may use ranges, e.g. [a-d] = [abcd])

The reason these regexes are similar is that a character class is a shorthand for an "or" (but only for single characters). In an alternation, you can also do something like (abc|def) which does not translate to a character class.

How to download and install if you have SUSE. As an example I am downloading the tablefunc module so I can use crosstab. I have PostgreSQL 9.6.1.

right-click desktop, terminal, type:

sudo zypper in postgreql-contrib

Enter credentials, continue by typing:

y

Run query (I ran mine from pgAdminIII):

CREATE EXTENSION tablefunc;

You should now have the crosstab function.

I did not have to restart.

I had named my file dockerfile instead of Dockerfile (capitalized), and once I changed that, it started processing my "Dockerfile".

Networking code is notoriously difficult to write, test and debug.

You often have lots of things to consider such as:

• what "endian" will you use for the data that is exchanged (Intel x86/x64 is based on little-endian) - systems that use big-endian can still read data that is in little-endian (and vice versa), but they have to rearrange the data. When documenting your "protocol" just make it clear which one you are using.

• are there any "settings" that have been set on the sockets which can affect how the "stream" behaves (e.g. SO_LINGER) - you might need to turn certain ones on or off if your code is very sensitive

• how does congestion in the real world which causes delays in the stream affect your reading/writing logic

If the "message" being exchanged between a client and server (in either direction) can vary in size then often you need to use a strategy in order for that "message" to be exchanged in a reliable manner (aka Protocol).

Here are several different ways to handle the exchange:

• have the message size encoded in a header that precedes the data - this could simply be a "number" in the first 2/4/8 bytes sent (dependent on your max message size), or could be a more exotic "header"

• use a special "end of message" marker (sentinel), with the real data encoded/escaped if there is the possibility of real data being confused with an "end of marker"

• use a timeout....i.e. a certain period of receiving no bytes means there is no more data for the message - however, this can be error prone with short timeouts, which can easily be hit on congested streams.

• have a "command" and "data" channel on separate "connections"....this is the approach the FTP protocol uses (the advantage is clear separation of data from commands...at the expense of a 2nd connection)

Each approach has its pros and cons for "correctness".

The code below uses the "timeout" method, as that seems to be the one you want.

See http://msdn.microsoft.com/en-us/library/bk6w7hs8.aspx. You can get access to the NetworkStream on the TCPClient so you can change the ReadTimeout.

string SendCmd(string cmd, string ip, int port)
{
  var client = new TcpClient(ip, port);
  var data = Encoding.GetEncoding(1252).GetBytes(cmd);
  var stm = client.GetStream();
  // Set a 250 millisecond timeout for reading (instead of Infinite the default)
  stm.ReadTimeout = 250;
  stm.Write(data, 0, data.Length);
  byte[] resp = new byte[2048];
  var memStream = new MemoryStream();
  int bytesread = stm.Read(resp, 0, resp.Length);
  while (bytesread > 0)
  {
      memStream.Write(resp, 0, bytesread);
      bytesread = stm.Read(resp, 0, resp.Length);
  }
  return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}

As a footnote for other variations on this writing network code...when doing a Read where you want to avoid a "block", you can check the DataAvailable flag and then ONLY read what is in the buffer checking the .Length property e.g. stm.Read(resp, 0, stm.Length);

— :: — :: \u2014

When representing the m-dash in a JavaScript text string for output to HTML, note that it will be represented by its unicode value. There are cases when ampersand characters ('&') will not be resolved—notably certain contexts within JSX. In this case, neither — nor — will work. Instead you need to use the Unicode escape sequence: \u2014.

For example, when implementing a render() method to output text from a JavaScript variable:

render() {
   let text='JSX transcoders will preserve the & character—to ' 
            + 'protect from possible script hacking and cross-site hacks.'
   return (
     <div>{text}</div>
   )
}

This will output:

<div>JSX transcoders will preserve the & character&mdash;to protect from possible script hacking and cross-site hacks.</div>

Instead of the &– prefixed representation, you should use \u2014:

let text='JSX transcoders will preserve the & character\u2014to …'

In case you do not want to use Asset Catalog, you can add an iOS 7 icon for an old app by creating a 120x120 .png image. Name it Icon-120.png and drag in to the project.

Under TARGET > Your App > Info > Icon files, add one more entry in the Target Properties:

I tested on Xcode 5 and an app was submitted without the missing retina icon warning.

I have a similar problem, but now I know the reason.

After we use git init, we should add a remote repository using

git remote add name url

Pay attention to the word name, if we change it to origin, then this problem will not happen.

Of course, if we change it to py, then using git pull py branch and git push py branch every time you pull and push something will also be OK.

Since I never can remember that LINQ calls it Where, Select and Aggregate instead of Filter, Map and Reduce so I created a few extension methods you can use:

IEnumerable<string> myStrings = new List<string>() { "1", "2", "3", "4", "5" };
IEnumerable<int> convertedToInts = myStrings.Map(s => int.Parse(s));
IEnumerable<int> filteredInts = convertedToInts.Filter(i => i <= 3); // Keep 1,2,3
int sumOfAllInts = filteredInts.Reduce((sum, i) => sum + i); // Sum up all ints
Assert.Equal(6, sumOfAllInts); // 1+2+3 is 6

Here are the 3 methods (from https://github.com/cs-util-com/cscore/blob/master/CsCore/PlainNetClassLib/src/Plugins/CsCore/com/csutil/collections/IEnumerableExtensions.cs ):

public static IEnumerable<R> Map<T, R>(this IEnumerable<T> self, Func<T, R> selector) {
    return self.Select(selector);
}

public static T Reduce<T>(this IEnumerable<T> self, Func<T, T, T> func) {
    return self.Aggregate(func);
}

public static IEnumerable<T> Filter<T>(this IEnumerable<T> self, Func<T, bool> predicate) {
    return self.Where(predicate);
}

Some more details from https://github.com/cs-util-com/cscore#ienumerable-extensions :

To be more specific, in order for a web application to send push notifications to a mobile device, such as the iPhone, the mobile device must have registered to receive push notifications for a particular application. The registration for push notification is done through a native app and can only be performed through a native app. Once the native app is registered for push notification, it can send the authorization token to the server, which can be used in conjunction with the certificate used to provision the native client, to send the push notifications to the mobile device.

As specified in another answer, one option is to 'wrap' your web application in a native application. Meaning that you would create a native application that basically presents a UIWebView (for iPhone dev) to the user showing your web application. While this pretty much functions in the same manner as the native browser, you would be able to add the ability to register for push notifications using the native controls.

It would be beneficial to you to review the Apple's push notification document as it provides some pretty good information on how push messaging functions on the iPhone.

No. Standard CSS does not provide the kind of thing you're looking for.

However, you might want to look into LESS and SASS.

These are two projects which aim to extend default CSS syntax by introducing additional features, including variables, nested rules, and other enhancements.

They allow you to write much more structured CSS code, and either of them will almost certainly solve your particular use case.

Of course, none of the browsers support their extended syntax (especially since the two projects each have different syntax and features), but what they do is provide a "compiler" which converts your LESS or SASS code into standard CSS, which you can then deploy on your site.

Try setting a custom CultureInfo for CurrentCulture and CurrentUICulture:

Globalization.CultureInfo customCulture = new Globalization.CultureInfo("en-US", true);

customCulture.DateTimeFormat.ShortDatePattern = "yyyy-MM-dd h:mm tt";

System.Threading.Thread.CurrentThread.CurrentCulture = customCulture;
System.Threading.Thread.CurrentThread.CurrentUICulture = customCulture;

DateTime newDate = System.Convert.ToDateTime(DateTime.Now.ToString("yyyy-MM-dd h:mm tt"));

here you are adding the foreign key for your "Child" table

ALTER TABLE child
ADD FOREIGN KEY (P_Id)
REFERENCES parent(P_Id) 
ON DELETE CASCADE
ON UPDATE CASCADE;

After that if you make a DELETE query on "Parent" table like this

DELETE FROM parent WHERE .....

since the child has a reference to parent with DELETE CASCADE, the "Child" rows also will be deleted! along with the "parent".

You probably shouldn't, and you can probably do what you want to do in a safer and simpler way. Technically to use variable number of arguments in C you include stdarg.h. From that you'll get the va_list type as well as three functions that operate on it called va_start(), va_arg() and va_end().

#include<stdarg.h>

int maxof(int n_args, ...)
{
    va_list ap;
    va_start(ap, n_args);
    int max = va_arg(ap, int);
    for(int i = 2; i <= n_args; i++) {
        int a = va_arg(ap, int);
        if(a > max) max = a;
    }
    va_end(ap);
    return max;
}

If you ask me, this is a mess. It looks bad, it's unsafe, and it's full of technical details that have nothing to do with what you're conceptually trying to achieve. Instead, consider using overloading or inheritance/polymorphism, builder pattern (as in operator<<() in streams) or default arguments etc. These are all safer: the compiler gets to know more about what you're trying to do so there are more occasions it can stop you before you blow your leg off.

With Internet Explorer you often have to specify the Pragma: public header as well for the download to function properly..

header('Pragma: public');

Just my 2 cents..

use

%cd SwitchFrequencyAnalysis

to change the current working directory for the notebook environment (and not just the subshell that runs your ! command).

you can confirm it worked with the pwd command like this:

!pwd

First, you have to create two animation resources in res/anim dir

slide_up.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
    android:duration="@android:integer/config_mediumAnimTime"
    android:fromYDelta="100%"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toXDelta="0">
</translate>
</set>

slide_bottom.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate 
    android:duration="@android:integer/config_mediumAnimTime" 
    android:fromYDelta="0%p" 
    android:interpolator="@android:anim/accelerate_interpolator" 
    android:toYDelta="100%p">
</translate>
</set>

then you have to create a style

<style name="DialogAnimation">
    <item name="android:windowEnterAnimation">@anim/slide_up</item>
    <item name="android:windowExitAnimation">@anim/slide_bottom</item>
</style>

and add this line to your class

dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation; //style id

Based in http://www.devexchanges.info/2015/10/showing-dialog-with-animation-in-android.html

Silverlight applications do not have direct access to machine.config.

I generally use array split because it's easier simple syntax and scales better with more than 2 partitions.

import numpy as np
partitions = 2
dfs = np.array_split(df, partitions)

np.split(df, [100,200,300], axis=0] wants explicit index numbers which may or may not be desirable.

On Windows:

You can create a shortcut executing

Anaconda3\pythonw.exe Anaconda3\cwp.py Anaconda3\envs\<your_env> Anaconda3\envs\<your env>\pythonw.exe Anaconda3\envs\<your_env>\Scripts\spyder-script.py

However, if you started spyder from your venv inside Anaconda shell, it creates this shortcut for you automatically in the Windows menu. The steps:

1. install spyder in your venv using the methods mentioned in the other answers here.

2. (in anaconda:) activate testenv

3. Look up the windows menu "recently added" or just search for "spyder" in the windows menu, find spyder (testenv) and

• [add that to taskbar] and / or

• [look up the file source location] and copy that to your desktop, e.g. from C:\Users\USER\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Anaconda3 (64-bit), where the spyder links for any of my environments can be found.

Now you can directly start spyder from a shortcut without the need to open anaconda prompt.

It's not print that does the formatting, It's a property of strings, so you can just use

newstring = "%.9f" % numvar

This can be used to get the first two characters as hours and last two as minutes. Same logic may be applied to seconds.

Enhanced for loop:

for (String element : array) {

    // rest of code handling current element
}

Traditional for loop equivalent:

for (int i=0; i < array.length; i++) {
    String element = array[i]; 

    // rest of code handling current element
}

Take a look at these forums: https://blogs.oracle.com/CoreJavaTechTips/entry/using_enhanced_for_loops_with

http://www.java-tips.org/java-se-tips/java.lang/the-enhanced-for-loop.html

var a = ["a","a","b","c","c"];

a.filter(function(value,index,self){ return (self.indexOf(value) !== index )})

Kind of an anonymous lookup table rather than a long switch statement:

return (const char *[]) {
    "bananas & monkeys",
    "Round and orange", 
    "APPLE",
}[enumVal];

If you want code is running on multiple servers with different environments,then we have need to use dirname(FILE) in an include or include_once statement. reason is follows. 1. Do not give absolute path to include files on your server. 2. Dynamically calculate the full path like absolute path.

Use a combination of dirname(FILE) and subsequent calls to itself until you reach to the home of your '/myfile.php'. Then attach this variable that contains the path to your included files.

I just had the same issue with Font Awesome. Turned out this was caused by a problem with FTP. The file was uploaded as text (ASCII) instead of binary, which corrupted the file. I simply changed my FTP software to binary, re-uploaded the font files, and then it all worked.

https://css-tricks.com/forums/topic/custom-fonts-returns-failed-to-decode-downloaded-font/ this helped me in the end I had the same issue with FTP transferring files as text

just add

android:gravity="center"

and done :)

Response status comes as second parameter in callback, (from docs):

// Simple GET request example :
$http.get('/someUrl').
  success(function(data, status, headers, config) {
    // this callback will be called asynchronously
    // when the response is available
  }).
  error(function(data, status, headers, config) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

It looks like you want a grid to evaluate your function, in which case you can use numpy.ogrid (open) or numpy.mgrid (fleshed out):

import numpy
my_grid = numpy.mgrid[[slice(0,1,0.1)]*6]

Would the use of <caption> be allowed?

<ul>
  <caption> Title of List </caption>
  <li> Item 1 </li>
  <li> Item 2 </li>
</ul>

Your code works, but it uses deprecated methods to do so. You should use the CSS text-align property to do this rather than the align property. Even so, it must be your browser or something else affecting it. Try this demo in Chrome (I had to disable normalize.css to get it to render).

• Source: http://jsfiddle.net/EDSWL/
• Demo: http://jsfiddle.net/EDSWL/show

In my case I get the same error title could not resolve all dependencies for configuration

However suberror said, it was due to a linting jar not loaded with its url given saying status 502 received, I ran the deployment command again, this time it succeeded.

Use a setter for the ViewChild:

 private contentPlaceholder: ElementRef;

 @ViewChild('contentPlaceholder') set content(content: ElementRef) {
    if(content) { // initially setter gets called with undefined
        this.contentPlaceholder = content;
    }
 }

The setter is called with an element reference once *ngIf becomes true.

Note, for Angular 8 you have to make sure to set { static: false }, which is a default setting in other Angular versions:

 @ViewChild('contentPlaceholder', { static: false })

Note: if contentPlaceholder is a component you can change ElementRef to your component Class:

  private contentPlaceholder: MyCustomComponent;

  @ViewChild('contentPlaceholder') set content(content: MyCustomComponent) {
     if(content) { // initially setter gets called with undefined
          this.contentPlaceholder = content;
     }
  }

SQLMenace's solution worked for me with a slight tweak to how data is deleted - DELETE FROM instead of TRUNCATE.

-- disable referential integrity
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL' 
GO 

EXEC sp_MSForEachTable 'DELETE FROM ?' 
GO 

-- enable referential integrity again 
EXEC sp_MSForEachTable 'ALTER TABLE ? WITH CHECK CHECK CONSTRAINT ALL' 
GO

I don't know about other browsers, but IE7 has a 2083 character limit for HTTP GET operations. Unless any other browsers have lower limits, I don't see why you'd need any more characters than 2083.

Here is the perfect example of downloading a file using javaScript.

Usage: download_file(fileURL, fileName);

The shortest way! it's working for me, Where NA is my default value.

<td th:text="${ins.eValue!=null}? ${ins.eValue}:'NA'" />

As said in the comments, the problem lies in your script. Actually, there are 2 problems:

• There is a matplotlib error, I guess that you're passing an argument as None somewhere. Maybe due to the defaultdict ?
• You call show() after each subplot. show() should be called once at the end of your script. The alternative is to use interactive mode, look for ion in matplotlib's documentation.

The most effective method is list comprehension, many people show their case, of course, it is also a good way to get an iterator through filter.

Filter receives a function and a sequence. Filter applies the passed function to each element in turn, and then decides whether to retain or discard the element depending on whether the function return value is True or False.

There is an example (get the odds in the tuple):

list(filter(lambda x:x%2==1, (1, 2, 4, 5, 6, 9, 10, 15)))  
# result: [1, 5, 9, 15]

Caution: You can also not handle iterators. Iterators are sometimes better than sequences.

Adding an approach to this old question just for the fun of it:

$ cat input.file # file containing input that needs to be processed
a;b;c;d;e
1;2;3;4;5
no delimiter here
124;adsf;15454
foo;bar;is;null;info

$ cat tmp.sh # showing off the script to do the job
#!/bin/bash
delim=';'
while read -r line; do  
    while [[ "$line" =~ "$delim" ]]; do
        line=$(cut -d"$delim" -f 2- <<<"$line")
    done
    echo "$line"
done < input.file

$ ./tmp.sh # output of above script/processed input file
e
5
no delimiter here
15454
info

Besides bash, only cut is used. Well, and echo, I guess.

There are a few options

Short Syntax

Using the host : guest format you can do any of the following:

volumes:
  # Just specify a path and let the Engine create a volume
  - /var/lib/mysql

  # Specify an absolute path mapping
  - /opt/data:/var/lib/mysql

  # Path on the host, relative to the Compose file
  - ./cache:/tmp/cache

  # User-relative path
  - ~/configs:/etc/configs/:ro

  # Named volume
  - datavolume:/var/lib/mysql

Long Syntax

As of docker-compose v3.2 you can use long syntax which allows the configuration of additional fields that can be expressed in the short form such as mount type (volume, bind or tmpfs) and read_only.

version: "3.2"
services:
  web:
    image: nginx:alpine
    ports:
      - "80:80"
    volumes:
      - type: volume
        source: mydata
        target: /data
        volume:
          nocopy: true
      - type: bind
        source: ./static
        target: /opt/app/static

networks:
  webnet:

volumes:
  mydata:

Check out https://docs.docker.com/compose/compose-file/#long-syntax-3 for more info.

First click once on your package and then click setting icon on Android Studio.

Close/Unselect Compact Empty Middle Packages

Then, right click your package and rename it.

Thats all.

Call myTextInputLayout.setError() instead of myEditText.setError().

These container and containment have double functionality on setting errors. Functionality you need is container's one. But you could require minimal version of 23 for that.

Steps to install curl in windows

Install cURL on Windows

There are 4 steps to follow to get cURL installed on Windows.

Step 1 and Step 2 is to install SSL library. Step 3 is to install cURL. Step 4 is to install a recent certificate

Step One: Install Visual C++ 2008 Redistributables

From https://www.microsoft.com/en-za/download/details.aspx?id=29 For 64bit systems Visual C++ 2008 Redistributables (x64) For 32bit systems Visual C++ 2008 Redistributables (x32)

Step Two: Install Win(32/64) OpenSSL v1.0.0k Light

From http://www.shininglightpro.com/products/Win32OpenSSL.html For 64bit systems Win64 OpenSSL v1.0.0k Light For 32bit systems Win32 OpenSSL v1.0.0k Light

Step Three: Install cURL

Depending on if your system is 32 or 64 bit, download the corresponding** curl.exe.** For example, go to the Win64 - Generic section and download the Win64 binary with SSL support (the one where SSL is not crossed out). Visit http://curl.haxx.se/download.html

Copy curl.exe to C:\Windows\System32

Step Four: Install Recent Certificates

Do not skip this step. Download a recent copy of valid CERT files from https://curl.haxx.se/ca/cacert.pem Copy it to the same folder as you placed curl.exe (C:\Windows\System32) and rename it as curl-ca-bundle.crt

If you have already installed curl or after doing the above steps, add the directory where it's installed to the windows path:

1 - From the Desktop, right-click My Computer and click Properties.
2 - Click Advanced System Settings .
3 - In the System Properties window click the Environment Variables button.
4 - Select Path and click Edit.
5 - Append ;c:\path to curl directory at the end.
5 - Click OK.
6 - Close and re-open the command prompt

There are 3 main ways to perform a case-insensitive search in Oracle without using full-text indexes.

Ultimately what method you choose is dependent on your individual circumstances; the main thing to remember is that to improve performance you must index correctly for case-insensitive searching.

1. Case your column and your string identically.

You can force all your data to be the same case by using UPPER() or LOWER():

select * from my_table where upper(column_1) = upper('my_string');

or

select * from my_table where lower(column_1) = lower('my_string');

If column_1 is not indexed on upper(column_1) or lower(column_1), as appropriate, this may force a full table scan. In order to avoid this you can create a function-based index.

create index my_index on my_table ( lower(column_1) );

If you're using LIKE then you have to concatenate a % around the string you're searching for.

select * from my_table where lower(column_1) LIKE lower('my_string') || '%';

This SQL Fiddle demonstrates what happens in all these queries. Note the Explain Plans, which indicate when an index is being used and when it isn't.

2. Use regular expressions.

From Oracle 10g onwards REGEXP_LIKE() is available. You can specify the _match_parameter_ 'i', in order to perform case-insensitive searching.

In order to use this as an equality operator you must specify the start and end of the string, which is denoted by the carat and the dollar sign.

select * from my_table where regexp_like(column_1, '^my_string$', 'i');

In order to perform the equivalent of LIKE, these can be removed.

select * from my_table where regexp_like(column_1, 'my_string', 'i');

Be careful with this as your string may contain characters that will be interpreted differently by the regular expression engine.

This SQL Fiddle shows you the same example output except using REGEXP_LIKE().

3. Change it at the session level.

The NLS_SORT parameter governs the collation sequence for ordering and the various comparison operators, including = and LIKE. You can specify a binary, case-insensitive, sort by altering the session. This will mean that every query performed in that session will perform case-insensitive parameters.

alter session set nls_sort=BINARY_CI

There's plenty of additional information around linguistic sorting and string searching if you want to specify a different language, or do an accent-insensitive search using BINARY_AI.

You will also need to change the NLS_COMP parameter; to quote:

The exact operators and query clauses that obey the NLS_SORT parameter depend on the value of the NLS_COMP parameter. If an operator or clause does not obey the NLS_SORT value, as determined by NLS_COMP, the collation used is BINARY.

The default value of NLS_COMP is BINARY; but, LINGUISTIC specifies that Oracle should pay attention to the value of NLS_SORT:

Comparisons for all SQL operations in the WHERE clause and in PL/SQL blocks should use the linguistic sort specified in the NLS_SORT parameter. To improve the performance, you can also define a linguistic index on the column for which you want linguistic comparisons.

So, once again, you need to alter the session

alter session set nls_comp=LINGUISTIC

As noted in the documentation you may want to create a linguistic index to improve performance

create index my_linguistc_index on my_table 
   (NLSSORT(column_1, 'NLS_SORT = BINARY_CI'));

I suggest writing a little script and doing multiple searches with Grep. I've never found a way to search for multiple patterns, and believe me, I've looked!

Like so, your shell file, with an embedded string:

 #!/bin/bash 
 grep *A6* "Alex A1 Alex A6 Alex A7 Bob A1 Chris A9 Chris A6";
 grep *A7* "Alex A1 Alex A6 Alex A7 Bob A1 Chris A9 Chris A6";
 grep *A8* "Alex A1 Alex A6 Alex A7 Bob A1 Chris A9 Chris A6";

Then run by typing myshell.sh.

If you want to be able to pass in the string on the command line, do it like this, with a shell argument--this is bash notation btw:

 #!/bin/bash 
 $stingtomatch = "${1}";
 grep *A6* "${stingtomatch}";
 grep *A7* "${stingtomatch}";
 grep *A8* "${stingtomatch}";

And so forth.

If there are a lot of patterns to match, you can put it in a for loop.

I think I did encounter the same issue as yours. I created a simple mvn project and used "mvn eclipse:eclipse" to setup a eclipse project.

For example, my source file "Router.java" locates in "java/main/org/jhoh/mvc". And Router.java wants to read file "routes" which locates in "java/main/org/jhoh/mvc/resources"

I run "Router.java" in eclipse, and eclipse's console got NullPointerExeption. I set pom.xml with this setting to make all *.class java bytecode files locate in build directory.

<build>
    <defaultGoal>package</defaultGoal>
    <directory>${basedir}/build</directory>
<build>

I went to directory "build/classes/org/jhoh/mvc/resources", and there is no "routes". Eclipse DID NOT copy "routes" to "build/classes/org/jhoh/mvc/resources"

I think you can copy your "install.xml" to your *.class bytecode directory, NOT in your source code directory.

fsevents is dealt differently in mac and other linux system. Linux system ignores fsevents whereas mac install it. As the above error message states that fsevents is optional and it is skipped in installation process.

You can run npm install --no-optional command in linux system to avoid above warning.

Something like this substitutions will be needed for your tables and field names.

Declare @TableUsers Table (User_ID, MyRowCount Int Identity(1,1)
Declare @i Int, @MaxI Int, @UserID nVarchar(50)

Insert into @TableUser
Select User_ID
From Users 
Where (My Criteria)
Select @MaxI = @@RowCount, @i = 1

While @i <= @MaxI
Begin
Select @UserID = UserID from @TableUsers Where MyRowCount = @i
Exec prMyStoredProc @UserID
Select

 @i = @i + 1, @UserID = null
End

You can return json in PHP this way:

header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;

To increase the amount of memory allocated to R you can use memory.limit

memory.limit(size = ...)

Or

memory.size(max = ...)

About the arguments

• size - numeric. If NA report the memory limit, otherwise request a new limit, in Mb. Only values of up to 4095 are allowed on 32-bit R builds, but see ‘Details’.
• max - logical. If TRUE the maximum amount of memory obtained from the OS is reported, if FALSE the amount currently in use, if NA the memory limit.

It means it's a decimal literal, as others have said. However, the origins are probably not those suggested elsewhere in this answer. From the C# Annotated Standard (the ECMA version, not the MS version):

The decimal suffix is M/m since D/d was already taken by double. Although it has been suggested that M stands for money, Peter Golde recalls that M was chosen simply as the next best letter in decimal.

A similar annotation mentions that early versions of C# included "Y" and "S" for byte and short literals respectively. They were dropped on the grounds of not being useful very often.

I know its too late but this solution is working perfect for both .net framework and .net core:

@System.Web.HttpUtility.JavaScriptStringEncode()

Yes, there is a difference, incase of x++(postincrement), value of x will be used in the expression and x will be incremented by 1 after the expression has been evaluated, on the other hand ++x(preincrement), x+1 will be used in the expression. Take an example:

public static void main(String args[])
{
    int i , j , k = 0;
    j = k++; // Value of j is 0
    i = ++j; // Value of i becomes 1
    k = i++; // Value of k is 1
    System.out.println(k);  
}

Save the count as you go - and use validation to enforce it. I hacked this together - for keeping a count of unique votes and counts which keeps coming up!. But this time I have tested my suggestion! (notwithstanding cut/paste errors!).

The 'trick' here is to use the node priority to as the vote count...

The data is:

vote/$issueBeingVotedOn/user/$uniqueIdOfVoter = thisVotesCount, priority=thisVotesCount vote/$issueBeingVotedOn/count = 'user/'+$idOfLastVoter, priority=CountofLastVote

,"vote": {
  ".read" : true
  ,".write" : true
  ,"$issue" : {
    "user" : {
      "$user" : {
        ".validate" : "!data.exists() && 
             newData.val()==data.parent().parent().child('count').getPriority()+1 &&
             newData.val()==newData.GetPriority()" 

user can only vote once && count must be one higher than current count && data value must be same as priority.

      }
    }
    ,"count" : {
      ".validate" : "data.parent().child(newData.val()).val()==newData.getPriority() &&
             newData.getPriority()==data.getPriority()+1 "
    }

count (last voter really) - vote must exist and its count equal newcount, && newcount (priority) can only go up by one.

  }
}

Test script to add 10 votes by different users (for this example, id's faked, should user auth.uid in production). Count down by (i--) 10 to see validation fail.

<script src='https://cdn.firebase.com/v0/firebase.js'></script>
<script>
  window.fb = new Firebase('https:...vote/iss1/');
  window.fb.child('count').once('value', function (dss) {
    votes = dss.getPriority();
    for (var i=1;i<10;i++) vote(dss,i+votes);
  } );

function vote(dss,count)
{
  var user='user/zz' + count; // replace with auth.id or whatever
  window.fb.child(user).setWithPriority(count,count);
  window.fb.child('count').setWithPriority(user,count);
}
</script>

The 'risk' here is that a vote is cast, but the count not updated (haking or script failure). This is why the votes have a unique 'priority' - the script should really start by ensuring that there is no vote with priority higher than the current count, if there is it should complete that transaction before doing its own - get your clients to clean up for you :)

The count needs to be initialised with a priority before you start - forge doesn't let you do this, so a stub script is needed (before the validation is active!).

Generally speaking:

all and any are functions that take some iterable and return True, if

• in the case of all(), no values in the iterable are falsy;
• in the case of any(), at least one value is truthy.

A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.

Any non-booleans in the iterable will be fine — bool(x) will coerce any x according to these rules: 0, 0.0, None, [], (), [], set(), and other empty collections will yield False, anything else True. The docstring for bool uses the terms 'true'/'false' for 'truthy'/'falsy', and True/False for the concrete boolean values.

In your specific code samples:

You misunderstood a little bit how these functions work. Hence, the following does something completely not what you thought:

if any(foobars) == big_foobar:

...because any(foobars) would first be evaluated to either True or False, and then that boolean value would be compared to big_foobar, which generally always gives you False (unless big_foobar coincidentally happened to be the same boolean value).

Note: the iterable can be a list, but it can also be a generator/generator expression (˜ lazily evaluated/generated list) or any other iterator.

What you want instead is:

if any(x == big_foobar for x in foobars):

which basically first constructs an iterable that yields a sequence of booleans—for each item in foobars, it compares the item to big_foobar and emits the resulting boolean into the resulting sequence:

tmp = (x == big_foobar for x in foobars)

then any walks over all items in tmp and returns True as soon as it finds the first truthy element. It's as if you did the following:

In [1]: foobars = ['big', 'small', 'medium', 'nice', 'ugly']                                        

In [2]: big_foobar = 'big'                                                                          

In [3]: any(['big' == big_foobar, 'small' == big_foobar, 'medium' == big_foobar, 'nice' == big_foobar, 'ugly' == big_foobar])        
Out[3]: True

Note: As DSM pointed out, any(x == y for x in xs) is equivalent to y in xs but the latter is more readable, quicker to write and runs faster.

Some examples:

In [1]: any(x > 5 for x in range(4))
Out[1]: False

In [2]: all(isinstance(x, int) for x in range(10))
Out[2]: True

In [3]: any(x == 'Erik' for x in ['Erik', 'John', 'Jane', 'Jim'])
Out[3]: True

In [4]: all([True, True, True, False, True])
Out[4]: False

Here's a plugin which can list all event handlers for any given element/event:

$.fn.listHandlers = function(events, outputFunction) {
    return this.each(function(i){
        var elem = this,
            dEvents = $(this).data('events');
        if (!dEvents) {return;}
        $.each(dEvents, function(name, handler){
            if((new RegExp('^(' + (events === '*' ? '.+' : events.replace(',','|').replace(/^on/i,'')) + ')$' ,'i')).test(name)) {
               $.each(handler, function(i,handler){
                   outputFunction(elem, '\n' + i + ': [' + name + '] : ' + handler );
               });
           }
        });
    });
};

Use it like this:

// List all onclick handlers of all anchor elements:
$('a').listHandlers('onclick', console.info);

// List all handlers for all events of all elements:
$('*').listHandlers('*', console.info);

// Write a custom output function:
$('#whatever').listHandlers('click',function(element,data){
    $('body').prepend('<br />' + element.nodeName + ': <br /><pre>' + data + '<\/pre>');
});

There is another javascript library based on SVG. It is called Protovis and it comes from Stanford Visualization Group

It also allows making nice interactive graphics and visualizations.

http://vis.stanford.edu/protovis/ex/

Although it is only for modern web browsers

UPDATE: The protovis team has moved to another library called d3.js (Data Driven Documents) as they said:

"The Protovis team is now developing a new visualization library, D3.js, with improved support for animation and interaction. D3 builds on many of the concepts in Protovis"

The new library can now be found in:

http://mbostock.github.com/d3/

UPDATE 2:

"Rickshaw" is a JavaScript toolkit for creating interactive time series graphs. Based on d3.js that simplifies a lot the work with d3.js although is a little bit less powerful.

On SuSE, there are two different configuration files for PHP: one for Apache, and one for CLI (command line interface). In the /etc/php5/ directory, you will find an "apache2" directory and a "cli" directory. Each has a "php.ini" file. The files are for the same purpose (php configuration), but apply to the two different ways of running PHP. These files, among other things, load the modules PHP uses.

If your OS is similar, then these two files are probably not the same. Your Apache php.ini is probably loading the gearman module, while the cli php.ini isn't. When the module was installed (auto or manual), it probably only updated the Apache php.ini file.

You could simply copy the Apache php.ini file over into the cli directory to make the CLI environment exactly like the Apache environment.

Or, you could find the line that loads the gearman module in the Apache file and copy/paste just it to the CLI file.

From the Twitter FAQ:

Most integrations with the API will require you to identify your application to Twitter by way of an API key. On the Twitter platform, the term "API key" usually refers to what's called an OAuth consumer key. This string identifies your application when making requests to the API. In OAuth 1.0a, your "API keys" probably refer to the combination of this consumer key and the "consumer secret," a string that is used to securely "sign" your requests to Twitter.

Firstly, in your react project go to your package.json and adjust this line line of code to match your destination domain address + folder:

"homepage": "https://yourwebsite.com/your_folder_name/",

Secondly, go to terminal in your react project and type:

npm run build

Now, take all files from that newly created build folder and upload them into your_folder_name, with filezilla in subfolder like this:

public_html/your_folder_name

Check in the browser!

In Typescript and ES6 you can also use for..of:

for (var product of products) {
     console.log(product.product_desc)
}

which will be transcoded to javascript:

for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
    var product = products_1[_i];
    console.log(product.product_desc);
}

Appreciate there are a few good answers here, but as I've just lost time working this out, hopefully this can help someone.

In my case, everything had been working fine, then stopped for no apparent reason with the error stated in the question.

IIS was running as Network service and Network Service had been set up on SQL Server previously (see other answers to this post). Server roles and user mappings looked correct.

The issue was; for absolutely no apparent reason; Network Service had switched to 'Deny' Login rights in the database.

To fix:

1. Open SSMS > Security > Logins.
2. Right click 'NT AUTHORITY\NETWORK SERVICE' and Click Properties.
3. Go to 'Status' tab and set Permission to Connect To Database Engine To 'Grant'.

You're after the zip function.

Taken directly from the question: How to merge lists into a list of tuples in Python?

>>> list_a = [1, 2, 3, 4]
>>> list_b = [5, 6, 7, 8]
>>> zip(list_a,list_b)
[(1, 5), (2, 6), (3, 7), (4, 8)]

You can go with option 3 if you modify your abstract base class to require the property value in the constructor, you won't miss any paths. I'd really consider this option.

abstract class Aunt
{
    protected int MyInt;
    protected Aunt(int myInt)
    {
        MyInt = myInt;
    }

}

Of course, you then still have the option of making the field private and then, depending on the need, exposing a protected or public property getter.

Look at my solution:

1.Insert this function (and variable) into your javascript file:

var runFunctionQueue_callback;

function runFunctionQueue(f, index, callback) {

  var next_index = index + 1

  if (callback !== undefined) runFunctionQueue_callback = callback;

  if (f[next_index] !== undefined) {
    console.log(index + ' Next function avalaible -> ' + next_index);
    $.ajax({
      type: 'GET',
      url: f[index].file,
      data: (f[index].data),
      complete: function() {
        runFunctionQueue(f, next_index);
      }
    });
  } else {
    console.log(index + ' Last function');
    $.ajax({
      type: 'GET',
      url: f[index].file,
      data: (f[index].data),
      async: false,
      complete: runFunctionQueue_callback
    });
  }
}

2.Buil an array with your requests, like this:

var f = [
           {file: 'file_path', data: {action: 'action', data: 'any_data}},
           {file: 'file_path', data: {action: 'action', data: 'any_data}},
           {file: 'file_path', data: {action: 'action', data: 'any_data}},
           {file: 'file_path', data: {action: 'action', data: 'any_data}}
        ];

3.Create callback function:

function Function_callback() {
  alert('done');
}

4.Call the runFunctionQueue function with parameters:

runFunctionQueue(f, 0, QuestionInsert_callback);
// first parameter: array with requests data
// second parameter: start from first request
// third parameter: the callback function

In simple words:

1. Padding - creates space inside the view's border.
2. Margin - creates space outside the view's border.

Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%" - but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.

It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.

To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%".

Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.

Updated answer to reflect question update:

I say that doing a WHERE field LIKE "%value%" is slower than WHERE field LIKE "value%" if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:

1/ If you do SELECT field FROM table WHERE field LIKE "%value%", MySQL will scan the entire table, and only send the fields containing "value".

2/ If you do SELECT field FROM table and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.

Solution: Please do use the WHERE clause, and use EXPLAIN to see the performance.

This was marked as a duplicate to this question https://stackoverflow.com/questions/24401064/understanding-and-solving-the-diamond-problems-in-java

You need Java 8 to get a multiple inheritance problem, but it is still not a diamon problem as such.

interface A {
    default void hi() { System.out.println("A"); }
}

interface B {
    default void hi() { System.out.println("B"); }
}

class AB implements A, B { // won't compile
}

new AB().hi(); // won't compile.

As JB Nizet comments you can fix this my overriding.

class AB implements A, B {
    public void hi() { A.super.hi(); }
}

However, you don't have a problem with

interface D extends A { }

interface E extends A { }

interface F extends A {
    default void hi() { System.out.println("F"); }
}

class DE implement D, E { }

new DE().hi(); // prints A

class DEF implement D, E, F { }

new DEF().hi(); // prints F as it is closer in the heirarchy than A.

simpler:

re.findall(r'/(?!ignoreme)(\w+)',  "/hello /ignoreme and /ignoreme2 /ignoreme2M.")

you will get:

['hello']

Got here from Google but this wasn't much help for me. It turned out that there is a minimum aspect ratio of 3:1 required for the logo. Mine was almost 4:1. I used Gimp to crop it to exactly 3:1 and voila - my logo is now shown on FB.

Its a common error which happens when we try to access a database which doesn't exist. So create the database using

CREATE DATABASE blog_development;

The error commonly occours when we have dropped the database using

DROP DATABASE blog_development;

and then try to access the database.

if(isnull({uspRptMonthlyGasRevenueByGas;1.YearTotal})) = true then
   "nd"
else
    totext({uspRptMonthlyGasRevenueByGas;1.YearTotal},'###.00')

The above logic should be what you are looking for.

Vadim Shender response is great. You can also use a simpler decorator like below:

import datetime
def calc_timing(original_function):                            
    def new_function(*args,**kwargs):                        
        start = datetime.datetime.now()                     
        x = original_function(*args,**kwargs)                
        elapsed = datetime.datetime.now()                      
        print("Elapsed Time = {0}".format(elapsed-start))     
        return x                                             
    return new_function()  

@calc_timing
def a_func(*variables):
    print("do something big!")

   string myString = "abcdxxx";
   if (myString.Length<3)
      return;
   string newString=myString.Remove(myString.Length - 3, 3);

I was also facing the same issue until I added the type="module" to the script.

Before it was like this

<script src="../src/main.js"></script>

And after changing it to

<script type="module" src="../src/main.js"></script>

It worked perfectly.

This worked for me:

echo(header('content-type: text/xml'));

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

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

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

Add system variable path, this path is where jupyter and other scripts are located

PATH -->

`C:\Users\<userName>\AppData\Roaming\Python\Python39\Scripts`

Like in my laptop PATH is:

"C:\Users\developer\AppData\Roaming\Python\Python39\Scripts"

After that, You will be able to run jupyter from any folder & any directory by running the below command

jupyter notebook

For example, i created a table :

DataTable dt = new DataTable ();
dt.Columns.Add("Title", typeof(string));
dt.Columns.Add("Value", typeof(int));

Add recorde to table :

DataRow row = dt.NewRow();
row["Title"] = "Price"
row["Value"] = 2000;
dt.Rows.Add(row);

or :

dt.Rows.Add("Price",2000);

finally :

combo.DataSource = dt;
combo.DisplayMember = "Title";
combo.ValueMember = "Value";

Fibonacci sequence is: 1, 1, 2, 3, 5, 8, ....

That is f(1) = 1, f(2) = 1, f(3) = 2, ..., f(n) = f(n-1) + f(n-2).

My favorite implementation (simplest and yet achieves a light speed in compare to other implementations) is this:

def fibonacci(n):
    a, b = 0, 1
    for _ in range(1, n):
        a, b = b, a + b
    return b

Test

>>> [fibonacci(i) for i in range(1, 10)]
[1, 1, 2, 3, 5, 8, 13, 21, 34]

Timing

>>> %%time
>>> fibonacci(100**3)
CPU times: user 9.65 s, sys: 9.44 ms, total: 9.66 s
Wall time: 9.66 s

Edit: an example visualization for this implementations.

In matrix multiplication there are 3 for loop, we are using since execution of each for loop requires time complexity O(n). So for three loops it becomes O(n^3)

I recently found (Jan/2020) an article about all this. I'll add a link here....sometimes having 2 different people show/explain it helps someone trying to learn it.

http://luisquintanilla.me/2017/12/25/client-credentials-authentication-csharp/

I also faced same issue i followed the best and the easiest way

Environment : Windows

IDE : Android Studio

Tools>flutter(last option)> select flutter clean

after flutter clean finished you all set and good to go.

In my case, I have used a URL object instead Path.

File

File file = new File("my_path");
URL url = file.toURI().toURL();

Resource in classpath using classloader

URL url = MyClass.class.getClassLoader().getResource("resource_name")

When I need to read the content, I can use the following code:

InputStream stream = url.openStream();

And you can access the content using an InputStream.

This will work:

DECLARE @MyValue NVarChar(4000) = 'something';

SELECT S.name SchemaName, T.name TableName
INTO #T
FROM sys.schemas S INNER JOIN
     sys.tables T ON S.schema_id = T.schema_id;

WHILE (EXISTS (SELECT * FROM #T)) BEGIN
  DECLARE @SQL NVarChar(4000) = 'SELECT * FROM $$TableName WHERE (0 = 1) ';
  DECLARE @TableName NVarChar(1000) = (
    SELECT TOP 1 SchemaName + '.' + TableName FROM #T
  );
  SELECT @SQL = REPLACE(@SQL, '$$TableName', @TableName);

  DECLARE @Cols NVarChar(4000) = '';

  SELECT
    @Cols = COALESCE(@Cols + 'OR CONVERT(NVarChar(4000), ', '') + C.name + ') = CONVERT(NVarChar(4000), ''$$MyValue'') '
  FROM sys.columns C
  WHERE C.object_id = OBJECT_ID(@TableName);

  SELECT @Cols = REPLACE(@Cols, '$$MyValue', @MyValue);
  SELECT @SQL = @SQL + @Cols;

  EXECUTE(@SQL);

  DELETE FROM #T
  WHERE SchemaName + '.' + TableName = @TableName;
END;

DROP TABLE #T;

A couple caveats, though. First, this is outrageously slow and non-optimized. All values are being converted to nvarchar simply so that they can be compared without error. You may run into problems with values like datetime not converting as expected and therefore not being matched when they should be (false negatives).

The WHERE (0 = 1) is there to make building the OR clause easier. If there are not matches you won't get any rows back.

You may approach this differently; omit the use of the :empty pseudo-class and utilize input events to detect a significant value in the <input> field and style it accordingly:

var inputs = document.getElementsByTagName('input');_x000D_
_x000D_
for (var i = 0; i < inputs.length; i++) {_x000D_
  var input = inputs[i];_x000D_
  input.addEventListener('input', function() {_x000D_
    var bg = this.value ? 'green' : 'red';_x000D_
    this.style.backgroundColor = bg;_x000D_
  });_x000D_
}

body {_x000D_
  padding: 40px;_x000D_
}_x000D_
#inputList li {_x000D_
  list-style-type: none;_x000D_
  padding-bottom: 1.5em;_x000D_
}_x000D_
#inputList li input,_x000D_
#inputList li label {_x000D_
  float: left;_x000D_
  width: 10em;_x000D_
}_x000D_
#inputList li input {_x000D_
  color: white;_x000D_
  background-color: red;_x000D_
}_x000D_
#inputList li label {_x000D_
  text-align: right;_x000D_
  padding-right: 1em;_x000D_
}

<ul id="inputList">_x000D_
  <li>_x000D_
    <label for="username">Enter User Name:</label>_x000D_
    <input type="text" id="username" />_x000D_
  </li>_x000D_
  <li>_x000D_
    <label for="password">Enter Password:</label>_x000D_
    <input type="password" id="password" />_x000D_
  </li>_x000D_
</ul>

• Another post on DOM Mutation Events, suggesting the use of input Events (DOM Mutation Events are now deprecated in DOM level 4, and have been replaced by DOM Mutation Observers).

Disclaimer: note that input events are currently experimental, and probably not widely supported.

Go into your project structure, under project Settings, Modules, select the dependencies table. For each dependency, change the scope from 'Test' to 'Compile'.

Use an extension to UITableView to fetch the cell that contains any view:

@Paulw11's answer of setting up a custom cell type with a delegate property that sends messages to the table view is a good way to go, but it requires a certain amount of work to set up.

I think walking the table view cell's view hierarchy looking for the cell is a bad idea. It is fragile - if you later enclose your button in a view for layout purposes, that code is likely to break.

Using view tags is also fragile. You have to remember to set up the tags when you create the cell, and if you use that approach in a view controller that uses view tags for another purpose you can have duplicate tag numbers and your code can fail to work as expected.

I have created an extension to UITableView that lets you get the indexPath for any view that is contained in a table view cell. It returns an Optional that will be nil if the view passed in actually does not fall within a table view cell. Below is the extension source file in it's entirety. You can simply put this file in your project and then use the included indexPathForView(_:) method to find the indexPath that contains any view.

//
//  UITableView+indexPathForView.swift
//  TableViewExtension
//

//  copyright notice is included.

import UIKit

public extension UITableView {
  
  /**
  This method returns the indexPath of the cell that contains the specified view
   
   - Parameter view: The view to find.
   
   - Returns: The indexPath of the cell containing the view, or nil if it can't be found
   
  */
  
    func indexPathForView(_ view: UIView) -> IndexPath? {
        let center = view.center
        let viewCenter = self.convert(center, from: view.superview)
        let indexPath = self.indexPathForRow(at: viewCenter)
        return indexPath
    }
}

To use it, you can simply call the method in the IBAction for a button that's contained in a cell:

func buttonTapped(_ button: UIButton) {
  if let indexPath = self.tableView.indexPathForView(button) {
    print("Button tapped at indexPath \(indexPath)")
  }
  else {
    print("Button indexPath not found")
  }
}

(Note that the indexPathForView(_:) function will only work if the view object it's passed is contained by a cell that's currently on-screen. That's reasonable, since a view that is not on-screen doesn't actually belong to a specific indexPath; it's likely to be assigned to a different indexPath when it's containing cell is recycled.)

EDIT:

You can download a working demo project that uses the above extension from Github: TableViewExtension.git

Here is what I use

function windowSizes(){
    var e = window,
        a = 'inner';
    if (!('innerWidth' in window)) {
        a = 'client';
        e = document.documentElement || document.body;
    }
    return {
        width: e[a + 'Width'],
        height: e[a + 'Height']
    };  
}

$(window).on('resize', function () {
    console.log( windowSizes().width,windowSizes().height );
});

As for now there is no proper solution, as @spro says.

However, if you have an in-flight response and are using ReadableStream, you can close the stream to cancel the request.

fetch('http://example.com').then((res) => {
  const reader = res.body.getReader();

  /*
   * Your code for reading streams goes here
   */

  // To abort/cancel HTTP request...
  reader.cancel();
});

First of all, you're missing a quote at the beginning but this is probably a copy/paste error.

In Python 3.x, the end=' ' part will place a space after the displayed string instead of a newline. To do the same thing in Python 2.x, you'd put a comma at the end:

print "Building internam Index for %d tile(s) ..." % len(inputTiles),

There are more than a few gateways out there, but I am not aware of a reliable gateway that is free. Most gateways like PayPal will provide you APIs that will allow you to process credit cards, as well as do things like void, charge, or refund.

The other thing you need to worry about is the coming of PCI compliance which basically says if you are not compliant, you (or the company you work for) will be liable by your Merchant Bank and/or Card Vendor for not being compliant by July of 2010. This will impose large fines on you and possibly revoke the ability for you to process credit cards.

All that being said companies like PayPal have a PHP SDK:

https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&content_ID=developer/library_download_sdks

Authorize.Net:

Those are two of the more popular ones for the United States.

There is no real speed difference. They are really all the same to the compiler. The difference is with the human beings trying to use and read your code.

For me that makes bool, true, and false the best choice in C++ code. In C code, there are some compilers around that don't support bool (I often have to work with old systems), so I might go with the defines in some circumstances.

headers = { 'User-Agent' : 'Mozilla/5.0' }
req = urllib2.Request('www.example.com', None, headers)
html = urllib2.urlopen(req).read()

Or, a bit shorter:

req = urllib2.Request('www.example.com', headers={ 'User-Agent': 'Mozilla/5.0' })
html = urllib2.urlopen(req).read()

Expanding on Dave's answer, you can set the contentMode of the button's imageView all in IB, without any code, using Runtime Attributes:

• 1 means UIViewContentModeScaleAspectFit,
• 2 would mean UIViewContentModeScaleAspectFill.

Answer given by kennyut/Kistian works very well but to get exact RDD like output when RDD consist of list of attributes e.g. [1,2,3,4] we can use flatmap command as below,

rdd = df.rdd.flatMap(list)
or 
rdd = df.rdd.flatmap(lambda x: list(x))

The accepted answer by @kevinsa5 is correct, but you might be thinking "I swear this code used to work and now it doesn't," and you would be right.

There was an API change in the MySQLdb library between 1.2.3 and 1.2.5. The 1.2.3 versions supported

cursor.execute("SELECT * FROM foo WHERE bar = %s", 'baz')

but the 1.2.5 versions require

cursor.execute("SELECT * FROM foo WHERE bar = %s", ['baz'])

as the other answers state. I can't find the change in the changelogs, and it's possible the earlier behavior was considered a bug.

The Ubuntu 14.04 repository has python-mysqldb 1.2.3, but Ubuntu 16.04 and later have python-mysqldb 1.3.7+.

If you're dealing with a legacy codebase that requires the old behavior but your platform is a newish Ubuntu, install MySQLdb from PyPI instead:

$ pip install MySQL-python==1.2.3

You will have to provide the entire user dn in SECURITY_PRINCIPAL

like this

env.put(Context.SECURITY_PRINCIPAL, "cn=username,ou=testOu,o=test"); 

Here is an example on how to use the onClickListener in Kotlin

button1.setOnClickListener(object : View.OnClickListener{
            override fun onClick(v: View?) {
                //Your code here
            }})

The difference is that const char * is a pointer to a const char, while char * const is a constant pointer to a char.

The first, the value being pointed to can't be changed but the pointer can be. The second, the value being pointed at can change but the pointer can't (similar to a reference).

There is also a

const char * const

which is a constant pointer to a constant char (so nothing about it can be changed).

Note:

The following two forms are equivalent:

const char *

and

char const *

The exact reason for this is described in the C++ standard, but it's important to note and avoid the confusion. I know several coding standards that prefer:

char const

over

const char

(with or without pointer) so that the placement of the const element is the same as with a pointer const.

You have to return a promise instead of a variable. So in your function just return:

return relationsManagerResource.GetParentId(nodeId)

And later resolve the returned promise. Or you can make another deferred and resolve theParentId with it.

Angular UI library has built-in directive ui-if for condition in template/Views upto angular ui 1.1.4

Example: Support in Angular UI upto ui 1.1.4

<div ui-if="array.length>0"></div>

ng-if available in all the angular version after 1.1.4

<div ng-if="array.length>0"></div>

if you have any data in array variable then only the div will appear

public OnClickListener moreListener = new OnClickListener() {

    @Override
      public void onClick(View v) {
          adapter.add("aaaa")
      }
}

Follow instructions (steps 1 to 3 don't needed in windows):

1. Find mysql config to edit:

   /etc/mysql/my.cnf (Mysql 5.5)

   /etc/mysql/conf.d/mysql.cnf (Mysql 5.6+)

2. Find bind-address=127.0.0.1 in config file change bind-address=0.0.0.0 (you can set bind address to one of your interface ips or like me use 0.0.0.0)

3. Restart mysql service run on console: service restart mysql

4. Create a user with a safe password for remote connection. To do this run following command in mysql (if you are linux user to reach mysql console run mysql and if you set password for root run mysql -p):

   GRANT ALL PRIVILEGES 
    ON *.* TO 'remote'@'%' 
    IDENTIFIED BY 'safe_password' 
    WITH GRANT OPTION;`
   

Now you should have a user with name of user and password of safe_password with capability of remote connect.

Found this useful explanation from http://ng-learn.org/2013/11/Bower-vs-npm/

On one hand npm was created to install modules used in a node.js environment, or development tools built using node.js such Karma, lint, minifiers and so on. npm can install modules locally in a project ( by default in node_modules ) or globally to be used by multiple projects. In large projects the way to specify dependencies is by creating a file called package.json which contains a list of dependencies. That list is recognized by npm when you run npm install, which then downloads and installs them for you.

On the other hand bower was created to manage your frontend dependencies. Libraries like jQuery, AngularJS, underscore, etc. Similar to npm it has a file in which you can specify a list of dependencies called bower.json. In this case your frontend dependencies are installed by running bower install which by default installs them in a folder called bower_components.

As you can see, although they perform a similar task they are targeted to a very different set of libraries.

Even after changing the compiler compliance setting to 1.6 or 1.7 from windows tab, then prefernces, then java, then compiler and setting the compiler compliance, I was still having this issue. The idea is that we need to go the the project folder, right click, Java and set compiler compliance to 1.6 or higer. This worked for me.

Many sites use AJAX/XHR/fetch to add, show, modify content dynamically and window.history API instead of in-site navigation so current URL is changed programmatically. Such sites are called SPA, short for Single Page Application.

Usual JS methods of detecting page changes

• MutationObserver (docs) to literally detect DOM changes:

  • How to change the HTML content as it's loading on the page

  • Performance of MutationObserver to detect nodes in entire DOM.

  • Simple example:

    let lastUrl = location.href; 
    new MutationObserver(() => {
      const url = location.href;
      if (url !== lastUrl) {
        lastUrl = url;
        onUrlChange();
      }
    }).observe(document, {subtree: true, childList: true});
    
    function onUrlChange() {
      console.log('URL changed!', location.href);
    }
    

• Event listener for sites that signal content change by sending a DOM event:

  • pjax:end on document used by many pjax-based sites e.g. GitHub,
    see How to run jQuery before and after a pjax load?
  • message on window used by e.g. Google search in Chrome browser,
    see Chrome extension detect Google search refresh
  • yt-navigate-finish used by Youtube,
    see How to detect page navigation on YouTube and modify its appearance seamlessly?

• Periodic checking of DOM via setInterval:
  Obviously this will work only in cases when you wait for a specific element identified by its id/selector to appear, and it won't let you universally detect new dynamically added content unless you invent some kind of fingerprinting the existing contents.

• Cloaking History API:

  let _pushState = History.prototype.pushState;
  History.prototype.pushState = function (state, title, url) {
    _pushState.call(this, state, title, url);
    console.log('URL changed', url)
  };
  

• Listening to hashchange, popstate events:

  window.addEventListener('hashchange', e => {
    console.log('URL hash changed', e);
    doSomething();
  });
  window.addEventListener('popstate', e => {
    console.log('State changed', e);
    doSomething();
  });
  

Extensions-specific methods

All above-mentioned methods can be used in a content script. Note that content scripts aren't automatically executed by the browser in case of programmatic navigation via window.history in the web page because only the URL was changed but the page itself remained the same (the content scripts run automatically only once in page lifetime).

Now let's look at the background script.

Detect URL changes in a background / event page.

There are advanced API to work with navigation: webNavigation, webRequest, but we'll use simple chrome.tabs.onUpdated event listener that sends a message to the content script:

• manifest.json:
  declare background/event page
  declare content script
  add "tabs" permission.

• background.js

  var rxLookfor = /^https?:\/\/(www\.)?google\.(com|\w\w(\.\w\w)?)\/.*?[?#&]q=/;
  chrome.tabs.onUpdated.addListener(function (tabId, changeInfo, tab) {
    if (rxLookfor.test(changeInfo.url)) {
      chrome.tabs.sendMessage(tabId, 'url-update');
    }
  });
  

• content.js

  chrome.runtime.onMessage.addListener((msg, sender, sendResponse) => {
    if (msg === 'url-update') {
      // doSomething();
    }
  });
  

Your css is fine, but I think it's not applying on divs. Just write simple class name and then try. You can check it at Jsfiddle.

.left {
  float: left;
  width: 125px;
  text-align: right;
  margin: 2px 10px;
  display: inline;
}

.right {
  float: left;
  text-align: left;
  margin: 2px 10px;
  display: inline;
}

This jQuery plugin (jQuery File Upload Demo) does it without flash, in the form it's using:

<input type='file' name='files[]' multiple />

I got frustrated too. My need was very straightforward. All I wanted was the ARGB color from the resources, so I wrote a simple static method.

protected static int getARGBColor(Context c, int resId)
        throws Resources.NotFoundException {

    TypedValue color = new TypedValue();
    try {
        c.getResources().getValue(resId, color, true);
    }
    catch (Resources.NotFoundException e) {
        throw(new Resources.NotFoundException(
                  String.format("Failed to find color for resourse id 0x%08x",
                                resId)));
    }
    if (color.type != TYPE_INT_COLOR_ARGB8) {
        throw(new Resources.NotFoundException(
                  String.format(
                      "Resourse id 0x%08x is of type 0x%02d. Expected TYPE_INT_COLOR_ARGB8",
                      resId, color.type))
        );
    }
    return color.data;
}

Try to make the bounds's size integer.

#include <math.h>
....

    if (ratio > 1) {
        bounds.size.width = resolution;
        bounds.size.height = round(bounds.size.width / ratio);
    } else {
        bounds.size.height = resolution;
        bounds.size.width = round(bounds.size.height * ratio);
    }

Please Use map() python function.

Input: In case of list of values

index = [u'CARBO1004' u'CARBO1006' u'CARBO1008' u'CARBO1009' u'CARBO1020']

encoded_string = map(str, index)

Output: ['CARBO1004', 'CARBO1006', 'CARBO1008', 'CARBO1009', 'CARBO1020']

For a Single string input:

index = u'CARBO1004'
# Use Any one of the encoding scheme.
index.encode("utf-8")  # To utf-8 encoding scheme
index.encode('ascii', 'ignore')  # To Ignore Encoding Errors and set to default scheme

Output: 'CARBO1004'

I know this an old subject but in case any finds this like myself:

I used the following code when i needed my directive to update values when the "parent scope" updated. Please by all means correct me if am doing something wrong as i am still learning angular, but this did what i needed;

directive:

directive('dateRangePrint', function(){
    return {
        restrict: 'E',
        scope:{
        //still using the single dir binding
            From: '@rangeFrom',
            To: '@rangeTo',
            format: '@format'
        },
        controller: function($scope, $element){

            $scope.viewFrom = function(){
                    return formatDate($scope.From, $scope.format);
                }

            $scope.viewTo = function(){
                    return formatDate($scope.To, $scope.format);
                }

            function formatDate(date, format){
                format = format || 'DD-MM-YYYY';

                //do stuff to date...

                return date.format(format);
            }

        },
        replace: true,
        // note the parenthesis after scope var
        template: '<span>{{ viewFrom() }} - {{ viewTo() }}</span>'
    }
})

This is because keypress events are fired before the new character is added to the value of the element (so the first keypress event is fired before the first character is added, while the value is still empty). You should use keyup instead, which is fired after the character has been added.

Note that, if your element #dSuggest is the same as input:text[name=dSuggest] you can simplify this code considerably (and if it isn't, having an element with a name that is the same as the id of another element is not a good idea).

$('#dSuggest').keypress(function() {
    var dInput = this.value;
    console.log(dInput);
    $(".dDimension:contains('" + dInput + "')").css("display","block");
});
