Here's how I did it in Swift 4.2:

extension Date {

    /// Create a date from specified parameters
    ///
    /// - Parameters:
    ///   - year: The desired year
    ///   - month: The desired month
    ///   - day: The desired day
    /// - Returns: A `Date` object
    static func from(year: Int, month: Int, day: Int) -> Date? {
        let calendar = Calendar(identifier: .gregorian)
        var dateComponents = DateComponents()
        dateComponents.year = year
        dateComponents.month = month
        dateComponents.day = day
        return calendar.date(from: dateComponents) ?? nil
    }
}

Usage:

let marsOpportunityLaunchDate = Date.from(year: 2003, month: 07, day: 07)

This works for stdout too:

spring.jpa.properties.hibernate.show_sql=true
spring.jpa.properties.hibernate.use_sql_comments=true
spring.jpa.properties.hibernate.format_sql=true

To log values:

logging.level.org.hibernate.type=trace

Just add this to application.properties.

Edit (2020.12.28): GitHub change default master branch to main branch since October 2020. See https://github.com/github/renaming

Update March 2013

Git 1.8.2 added the possibility to track branches.

"git submodule" started learning a new mode to integrate with the tip of the remote branch (as opposed to integrating with the commit recorded in the superproject's gitlink).

# add submodule to track master branch
git submodule add -b master [URL to Git repo];

# update your submodule
git submodule update --remote 

If you had a submodule already present you now wish would track a branch, see "how to make an existing submodule track a branch".

Also see Vogella's tutorial on submodules for general information on submodules.

Note:

git submodule add -b . [URL to Git repo];
                    ^^^

See git submodule man page:

A special value of . is used to indicate that the name of the branch in the submodule should be the same name as the current branch in the current repository.

See commit b928922727d6691a3bdc28160f93f25712c565f6:

submodule add: If --branch is given, record it in .gitmodules

This allows you to easily record a submodule.<name>.branch option in .gitmodules when you add a new submodule. With this patch,

$ git submodule add -b <branch> <repository> [<path>]
$ git config -f .gitmodules submodule.<path>.branch <branch>

reduces to

$ git submodule add -b <branch> <repository> [<path>]

This means that future calls to

$ git submodule update --remote ...

will get updates from the same branch that you used to initialize the submodule, which is usually what you want.

Original answer (February 2012):

A submodule is a single commit referenced by a parent repo.
Since it is a Git repo on its own, the "history of all commits" is accessible through a git log within that submodule.

So for a parent to track automatically the latest commit of a given branch of a submodule, it would need to:

• cd in the submodule
• git fetch/pull to make sure it has the latest commits on the right branch
• cd back in the parent repo
• add and commit in order to record the new commit of the submodule.

gitslave (that you already looked at) seems to be the best fit, including for the commit operation.

It is a little annoying to make changes to the submodule due to the requirement to check out onto the correct submodule branch, make the change, commit, and then go into the superproject and commit the commit (or at least record the new location of the submodule).

Other alternatives are detailed here.

You need to use jq 'keys[]'. For example:

echo '{"example1" : 1, "example2" : 2, "example3" : 3}' | jq 'keys[]'

Will output a line separated list:

"example1"
"example2"
"example3"

for a simple way to get all tables on the server, try this:

SET NOCOUNT ON
DECLARE @AllTables table (CompleteTableName nvarchar(4000))
INSERT INTO @AllTables (CompleteTableName)
    EXEC sp_msforeachdb 'select @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name from [?].sys.tables t inner join sys.schemas s on t.schema_id=s.schema_id'
SET NOCOUNT OFF
SELECT * FROM @AllTables ORDER BY 1

it will return a single column that contains the server+database+schema+table name: sample output:

CompleteTableName
--------------------------------------------
YourServer.YourDatabase1.YourSchema1.YourTable1
YourServer.YourDatabase1.YourSchema1.YourTable2
YourServer.YourDatabase1.YourSchema2.YourTable1
YourServer.YourDatabase1.YourSchema2.YourTable2
YourServer.YourDatabase2.YourSchema1.YourTable1

if you are not on SQL Server 2005 or up, replace the DECLARE @AllTables table with CREATE TABLE #AllTables and then every @AllTables with #AllTables and it will work.

EDIT
here is a version that will allow a search parameter to be used on any part or parts of the server+database+schema+table names:

SET NOCOUNT ON
DECLARE @AllTables table (CompleteTableName nvarchar(4000))
DECLARE @Search nvarchar(4000)
       ,@SQL   nvarchar(4000)
SET @Search=null --all rows
SET @SQL='select @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name from [?].sys.tables t inner join sys.schemas s on t.schema_id=s.schema_id WHERE @@SERVERNAME+''.''+''?''+''.''+s.name+''.''+t.name LIKE ''%'+ISNULL(@SEARCH,'')+'%'''

INSERT INTO @AllTables (CompleteTableName)
    EXEC sp_msforeachdb @SQL
SET NOCOUNT OFF
SELECT * FROM @AllTables ORDER BY 1

set @Search to NULL for all tables, set it to things like 'dbo.users' or 'users' or '.master.dbo' or even include wildcards like '.master.%.u', etc.

Best solution so far that I have seen is in FastAdapter library for recycler views. It has a EndlessRecyclerOnScrollListener.

Here is an example usage: EndlessScrollListActivity

Once I used it for endless scrolling list I have realised that the setup is a very robust. I'd definitely recommend it.

You can hide an image using javascript like this:

document.images['imageName'].style.visibility = hidden;

If that isn't what you are after, you need to explain yourself more clearly.

... Could not load file or assembly 'X' or one of its dependencies ...

Most likely it fails to load another dependency.

you could try to check the dependencies with a dependency walker.

I.e: https://www.dependencywalker.com/

Also check your build configuration (x86 / 64)

Edit: I also had this problem once when I was copying dlls in zip from a "untrusted" network share. The file was locked by Windows and the FileNotFoundException was raised.

See here: Detected DLLs that are from the internet and "blocked" by CASPOL

This works

declare @v int=A
select * from Table_Name where XYZ=202 
and 
dbkey=(case @v  when A then 'Some Value 1'
else 'Some Value 2'
end)

A new option is Jexus Manager for IIS Express,

https://blog.lextudio.com/2014/10/jexus-manager-for-iis-express/

It is just the management tool you know how to use.

sys.exit() should return an integer, not a string:

sys.exit(1)

The value 1 is in $?.

$ cat e.py
import sys
sys.exit(1)
$ python e.py
$ echo $?
1

Edit:

If you want to write to stderr, use sys.stderr.

Wrote a quick TDD Test for this

    [TestMethod]
    public void Test()
    {
        var input = @"ProjectName\Iteration\Release1\Iteration1";
        var pattern = @"\\Iteration";

        var rgx = new Regex(pattern);
        var result = rgx.Replace(input, "", 1);

        Assert.IsTrue(result.Equals(@"ProjectName\Release1\Iteration1"));
    }

rgx.Replace(input, "", 1); says to look in input for anything matching the pattern, with "", 1 time.

In order to get the http status code returned from the server, you can add validateStatus: status => true to axios options:

axios({
    method: 'POST',
    url: 'http://localhost:3001/users/login',
    data: { username, password },
    validateStatus: () => true
}).then(res => {
    console.log(res.status);
});

This way, every http response resolves the promise returned from axios.

https://github.com/axios/axios#handling-errors

Yes, it will serialize and deserialize a List<>. Just make sure you use the [XmlArray] attribute if in doubt.

[Serializable]
public class A
{
    [XmlArray]
    public List<string> strings;
}

This works with both Serialize() and Deserialize().

Or

jar xvf myproject.war

If inserting 'too much data' fails due to the max_allowed_packet setting of the database server, the following warning is raised:

SQLSTATE[08S01]: Communication link failure: 1153 Got a packet bigger than 
'max_allowed_packet' bytes

If this warning is catched as exception (due to the set error handler), the database connection is (probably) lost but the application doesn't know about this (failing inserts can have several causes). The next query in line, which can be as simple as:

SELECT 1 FROM DUAL

Will then fail with the error this SO-question started:

Error while sending QUERY packet. PID=18486

Simple test script to reproduce my explanation, try it with and without the error handler to see the difference in impact:

set_error_handler(function($errno, $errstr, $errfile, $errline, array $errcontext) {
    // error was suppressed with the @-operator
    if (0 === error_reporting()) {
        return false;
    }

    throw new ErrorException($errstr, 0, $errno, $errfile, $errline);
});

try
{
    // $oDb is instance of PDO
    var_dump($oDb->query('SELECT 1 FROM DUAL'));

    $oStatement = $oDb->prepare('INSERT INTO `test` (`id`, `message`) VALUES (NULL, :message);');
    $oStatement->bindParam(':message', $largetext, PDO::PARAM_STR);
    var_dump($oStatement->execute());
}
catch(Exception $e)
{
    $e->getMessage();
}
var_dump($oDb->query('SELECT 2 FROM DUAL'));

When I don't have permission to write a file out from Postgres I find that I can run the query from the command line.

psql -U user -d db_name -c "Copy (Select * From foo_table LIMIT 10) To STDOUT With CSV HEADER DELIMITER ',';" > foo_data.csv

May be this time stamp fit you better Code

Function LastInputTimeStamp() As Date
  LastInputTimeStamp = Now()
End Function

and each time you input data in defined cell (in my example below it is cell C36) you'll get a new constant time stamp. As an example in Excel file may use this

=IF(C36>0,LastInputTimeStamp(),"")

If using Android.

Make sure you have added the permission to write to your EXTERNAL_STORAGE to your AndroidManifest.xml.

Add this line to your AndroidManifest.xml file above and outside your <application> tag.

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

This will allow your application to write to the sdcard. This will help if your EXTERNAL_STORAGE is where you have stored your database on the device.

For This Issue check My answer at above given url

Using a request scoped bean outside of an actual web request

In Chrome, For "Selenium IDE", I was also struggling that it doesn't pause. It will pause, if you give as below:

• Command: pause
• Target: blank
• Value: 10000

This will pause for 10 seconds.

If the usage pattern justifies it, why not? While your team doesn't recognize the operator right away, with time they could. Humans learn new words all the time. Why not in programming?

The only caution I might state is that "^" doesn't have the short circuit semantics of your second boolean check. If you really need the short circuit semantics, then a static util method works too.

public static boolean xor(boolean a, boolean b) {
    return (a && !b) || (b && !a);
}

You can use https://github.com/mxcl/OMGHTTPURLRQ

id config = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:someID];
id session = [NSURLSession sessionWithConfiguration:config delegate:someObject delegateQueue:[NSOperationQueue new]];

OMGMultipartFormData *multipartFormData = [OMGMultipartFormData new];
[multipartFormData addFile:data1 parameterName:@"file1" filename:@"myimage1.png" contentType:@"image/png"];

NSURLRequest *rq = [OMGHTTPURLRQ POST:url:multipartFormData];

id path = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:@"upload.NSData"];
[rq.HTTPBody writeToFile:path atomically:YES];

[[session uploadTaskWithRequest:rq fromFile:[NSURL fileURLWithPath:path]] resume];

If you use this, check man sudo too:

#!/bin/bash

sudo echo "Hi, I'm root"

sudo -u nobody echo "I'm nobody"

sudo -u 1000 touch /test_user

There are none (at least in the standard Java library). Character sets vary from platform to platform so there isn't a standard list of them in Java.

There are some 3rd party libraries which contain these constants though. One of these is Guava (Google core libraries): http://guava-libraries.googlecode.com/svn/trunk/javadoc/com/google/common/base/Charsets.html

HTTP doesn't support redirection to a page using POST. When you redirect somewhere, the HTTP "Location" header tells the browser where to go, and the browser makes a GET request for that page. You'll probably have to just write the code for your page to accept GET requests as well as POST requests.

I think you can simple call like this, this will give you result value.

this.$route.query.page

Look image $route is object in Vue Instance and you can access with this keyword and next you can select object properties like above one :

Have a look Vue-router document for selecting queries value :

Vue Router Object

1. mydata$sCode is a vector, it's why nrow output is NULL.
2. mydata[mydata$sCode == 'CA',] returns data.frame where sCode == 'CA'. sCode includes character. That's why sum gives you the error.

3. subset(mydata, sCode='CA', select=c(sCode)), you should use sCode=='CA' instead sCode='CA'. Then subset returns you vector where sCode equals CA, so you should use

   length(subset(na.omit(mydata), sCode='CA', select=c(sCode)))

Or you can try this: sum(na.omit(mydata$sCode) == "CA")

Just putting it out there for newbies;

So First understand Word Context :

In english-lib. it means:

"The circumstances that form the setting for an event, statement, or idea, and in terms of which it can be fully understood and assessed."

"The parts of something written or spoken that immediately precede and follow a word or passage and clarify its meaning."

Now take the same understanding to programming world:

context of current state of the application/object. It lets newly created objects understand what has been going on. Typically you call it to get information regarding another part of your program (activity, package/application)

You can get the context by invoking getApplicationContext(), getContext(), getBaseContext() or this (when in the activity class).

To Get Context Anywhere in application use following code:

Create new class AppContext inside your android application

public class AppContext extends Application {

    private static Context context;

    public void onCreate(){
        super.onCreate();
        AppContext.context = getApplicationContext();
    }

    public static Context getAppContext() {
        return AppContext.context;
    }
}

Now any time you want application context in non-activity class, call this method and you have application context.

Hope this help ;)

empty() used to work for this, but the behavior of empty() has changed several times. As always, the php docs are always the best source for exact behavior and the comments on those pages usually provide a good history of the changes over time. If you want to check for a lack of object properties, a very defensive method at the moment is:

if (is_object($theObject) && (count(get_object_vars($theObject)) > 0)) {

If you already have a table pre_loaded_tbl with some data. You can use a trick to load the data into your table with following query

INSERT INTO TABLE tweet_table 
  SELECT  "my_data" AS my_column 
    FROM   pre_loaded_tbl 
   LIMIT   5;

Also please note that "my_data" is independent of any data in the pre_loaded_tbl. You can select any data and write any column name (here my_data and my_column). Hive does not require it to have same column name. However structure of select statement should be same as that of your tweet_table. You can use limit to determine how many times you can insert into the tweet_table.

However if you haven't' created any table, you will have to load the data using file copy or load data commands in above answers.

For me - here is a less confusing way of doing the socket.setTimeout

var request=require('https').get(
    url
   ,function(response){
        var r='';
        response.on('data',function(chunk){
            r+=chunk;
            });
        response.on('end',function(){
            console.dir(r);            //end up here if everything is good!
            });
        }).on('error',function(e){
            console.dir(e.message);    //end up here if the result returns an error
            });
request.on('error',function(e){
    console.dir(e);                    //end up here if a timeout
    });
request.on('socket',function(socket){
    socket.setTimeout(1000,function(){
        request.abort();                //causes error event ?
        });
    });

If you're willing and able to employ a little jquery, you can simply do this:

$('.someDiv').css([".radius", ".opacity"]);

If you have a javascript that already processes the page or you can enclose it somewhere in <script> tags. If so, wrap the above in the document ready function:

$(document).ready( function() {
  $('.someDiv').css([".radius", ".opacity"]);
}

I recently came across this while updating a wordpress plugin. The them has been changed which used a lot of "!important" directives across the css. I had to use jquery to force my styles because of the genius decision to declare !important on several tags.

This goes also for statements like this (auto-formatted by PyCharm):

    return combine_sample_generators(sample_generators['train']), \
           combine_sample_generators(sample_generators['dev']), \
           combine_sample_generators(sample_generators['test'])

Which will give the same style-warning. In order to get rid of it I had to rewrite it to:

    return \
        combine_sample_generators(sample_generators['train']), \
        combine_sample_generators(sample_generators['dev']), \
        combine_sample_generators(sample_generators['test'])

#fullDiv {
  position: absolute;
  margin: 0;
  padding: 0;
  left: 0;
  top: 0;
  bottom: 0;
  right: 0;
  overflow: hidden; /* or auto or scroll */
}

It should be quite simple if you are using LogBack or SLF4J. I do it as below

//imports
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

//Initialize logger
Logger logger = LoggerFactory.getLogger(<classname>.class);
try {
   //try something
} catch(Exception e){
   //Actual logging of error
   logger.error("some message", e);
}

just use class='text-center' in element for center heading.

<h2 class="text-center">sample center heading</h2>

use class='text-left' in element for left heading, and use class='text-right' in element for right heading.

Add the below lines in the log4j property file and it will shut the http logs :- log4j.logger.org.apache.http=OFF

var input_val=document.getElementById('my_variable');for (i=0; i<input_val.length; i++) {
xx = input_val[i];``
if (xx.name == "ans") {   
    new = xx.value;
    alert(new);    }}

there is one more difference, but only in internet explorer. It occurs when you mix HTML and SVG. if the parent is the 'other' of those two, then .parentNode gives the parent, while .parentElement gives undefined.

Swift 4.2

A quick one line solution. Replace originalString with the String you want to encode.

var encodedString = originalString.addingPercentEncoding(withAllowedCharacters: CharacterSet(charactersIn: "!*'();:@&=+$,/?%#[]{} ").inverted)

Online Playground Demo

I encountered this error when running on Mac 10.15.5 using homebrew and seems to be a more updated solution that works where the ones above did not.

There is a file called postmaster.pid which should is automatically deleted when postresql exits.

If it doesn't do the following

• brew services stop postgresql <--- Failing to exit before rm could corrupt db
• sudo rm /usr/local/var/postgres/postmaster.pid

ES6 for the win!

const b = 'b';
const c = 'c';

const data = {
    a: true,
    [b]: true, // dynamic property
    [`interpolated-${c}`]: true, // dynamic property + interpolation
    [`${b}-${c}`]: true
}

If you log data you get this:

{
  a: true,
  b: true,
  interpolated-c: true,
  b-c: true
}

This makes use of the new Computed Property syntax and Template Literals.

You forgot the HTTP part:

window.location.href = "http://example.com/Registration/Success/";

Additionally to overflow:hidden, use

white-space:nowrap;

Controller :

public ActionResult Refresh(string ID)
    {
        DetailsViewModel vm = new DetailsViewModel();  // Model
        vm.productDetails = _product.GetproductDetails(ID); 
        /* "productDetails " is a property in "DetailsViewModel"
        "GetProductDetails" is a method in "Product" class
        "_product" is an interface of "Product" class */

        return PartialView("_Details", vm); // Details is a partial view
    }

In yore index page you should to have refresh link :

     <a href="#" id="refreshItem">Refresh</a>

This Script should be also in your index page:

<script type="text/javascript">

    $(function () {
    $('a[id=refreshItem]:last').click(function (e) {
        e.preventDefault();

        var url = MVC.Url.action('Refresh', 'MyController', { itemId: '@(Model.itemProp.itemId )' }); // Refresh is an Action in controller, MyController is a controller name

        $.ajax({
            type: 'GET',
            url: url,
            cache: false,
            success: function (grid) {
                $('#tabItemDetails').html(grid);
                clientBehaviors.applyPlugins($("#tabProductDetails")); // "tabProductDetails" is an id of div in your "Details partial view"
            }
        });
    });
});

If you like to have the modal fade in rather than slide in (why is it called .fade anyway?) you can overwrite the class in your CSS file or directly in bootstrap.css with this:

.modal.fade{
    -webkit-transition: opacity .2s linear, none;
    -moz-transition: opacity .2s linear, none;
    -ms-transition: opacity .2s linear, none;
    -o-transition: opacity .2s linear, none;
    transition: opacity .2s linear, none;
    top: 50%;
}

If you don't want any effect just remove the fade class from the modal classes.

To the C language, '\0' means exactly the same thing as the integer constant 0 (same value zero, same type int).

To someone reading the code, writing '\0' suggests that you're planning to use this particular zero as a character.

This is a function that works for me:

function removeFromArray(array, value) {
    var idx = array.indexOf(value);
    if (idx !== -1) {
        array.splice(idx, 1);
    }
    return array;
}

View -> Datasets (bottom of menu, above Refresh)

You can use the opt(int) method and use a classical for loop.

The accepted way to rename a table in Laravel 4 is to use the Schema builder. So you would want to do:

Schema::rename('photos', 'images');

From http://laravel.com/docs/4.2/schema#creating-and-dropping-tables

If you really want to write out a raw SQL query yourself, you can always do:

DB::statement('alter table photos rename to images');

Note: Laravel's DB class also supports running raw SQL select, insert, update, and delete queries, like:

$users = DB::select('select id, name from users');

For more info, see http://laravel.com/docs/4.2/database#running-queries.

It seems the answers here do not support an enterprise use case where a Nexus server has multiple users and has project-based isolation (protection) based on user id ALONG with using an automated build (CI) system like Jenkins. You would not be able to create a settings.xml file to satisfy the different user ids needed for different projects. I am not sure how to solve this, except by opening Nexus up to anonymous access for reading repositories, unless the projects could store a project-specific generic user id in their pom.xml.

1) What is the difference between awk and sed ?

Both are tools that transform text. BUT awk can do more things besides just manipulating text. Its a programming language by itself with most of the things you learn in programming, like arrays, loops, if/else flow control etc You can "program" in sed as well, but you won't want to maintain the code written in it.

2) What kind of application are best use cases for sed and awk tools ?

Conclusion: Use sed for very simple text parsing. Anything beyond that, awk is better. In fact, you can ditch sed altogether and just use awk. Since their functions overlap and awk can do more, just use awk. You will reduce your learning curve as well.

The self closing script tag won't work, because the script tag can contain inline code, and HTML is not smart enough to turn on or off that feature based on the presence of an attribute.

On the other hand, HTML does have an excellent tag for including references to outside resources: the <link> tag, and it can be self-closing. It's already used to include stylesheets, RSS and Atom feeds, canonical URIs, and all sorts of other goodies. Why not JavaScript?

If you want the script tag to be self enclosed you can't do that as I said, but there is an alternative, though not a smart one. You can use the self closing link tag and link to your JavaScript by giving it a type of text/javascript and rel as script, something like below:

<link type="text/javascript" rel ="script" href="/path/tp/javascript" />

For enum type, I think this is a suitable way, and the difference between class is how to calculate hash value.

template <typename T>
struct EnumTypeHash {
  std::size_t operator()(const T& type) const {
    return static_cast<std::size_t>(type);
  }
};

enum MyEnum {};
class MyValue {};

std::unordered_map<MyEnum, MyValue, EnumTypeHash<MyEnum>> map_;

You have to use sizeof() function.

Code Snippet:

#include<bits/stdc++.h>
using namespace std;

int main()
{
      ios::sync_with_stdio(false);

      int arr[] ={5, 3, 6, 7};

      int size = sizeof(arr) / sizeof(arr[0]);
      cout<<size<<endl;

      return 0;
}

This code will count frequency and remove duplicate elements:

from collections import Counter

str1='the cat sat on the hat hat'

int_list=str1.split();

unique_list = []
for el in int_list:

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

print unique_list

c=Counter(int_list)

c.values()

c.keys()

print c

Another way to add that I used to 'hack' this solution was to do this: I set up a seperate computed value that would simply return the nested object value.

data : function(){
    return {
        my_object : {
            my_deep_object : {
                my_value : "hello world";
            }.
        },
    };
},
computed : {
    helper_name : function(){
        return this.my_object.my_deep_object.my_value;
    },
},
watch : {
    helper_name : function(newVal, oldVal){
        // do this...
    }
}

I'm late to the party, but this solution worked for me quite well. Based on this library, you can use a function lik this - setting the image, quality, max-width, and output format (jepg,png):

function compress(source_img_obj, quality, maxWidth, output_format){
    var mime_type = "image/jpeg";
    if(typeof output_format !== "undefined" && output_format=="png"){
        mime_type = "image/png";
    }

    maxWidth = maxWidth || 1000;
    var natW = source_img_obj.naturalWidth;
    var natH = source_img_obj.naturalHeight;
    var ratio = natH / natW;
    if (natW > maxWidth) {
        natW = maxWidth;
        natH = ratio * maxWidth;
    }

    var cvs = document.createElement('canvas');
    cvs.width = natW;
    cvs.height = natH;

    var ctx = cvs.getContext("2d").drawImage(source_img_obj, 0, 0, natW, natH);
    var newImageData = cvs.toDataURL(mime_type, quality/100);
    var result_image_obj = new Image();
    result_image_obj.src = newImageData;
    return result_image_obj;
}

Another solution without using any height but still fills 100% available height. Checkout this e.g on the codepen. http://codepen.io/gauravshankar/pen/PqoLLZ

For this html and body should have 100% height. This height is equal to the viewport height.

Make inner div position absolute and give top and bottom 0. This fills the div to available height. (height equal to body.)

html code:

<head></head>

<body>
  <div></div>
</body>

</html>

css code:

* {
  margin: 0;
  padding: 0;
}

html,
body {
  height: 100%;
  position: relative;
}

html {
  background-color: red;
}

body {
  background-color: green;
}

body> div {
  position: absolute;
  background-color: teal;
  width: 300px;
  top: 0;
  bottom: 0;
}

New answer to old question

None of the existing answers to this old question address the real problem.

The real problem was that xs:complexType cannot directly have a xs:extension as a child in XSD. The fix is to use xs:simpleContent first. Details follow...

Your XML,

<price currency="euros">20000.00</price>

will be valid against either of the following corrected XSDs:

Locally defined attribute type

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:element name="price">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="xs:decimal">
          <xs:attribute name="currency">
            <xs:simpleType>
              <xs:restriction base="xs:string">
                <xs:enumeration value="pounds" />
                <xs:enumeration value="euros" />
                <xs:enumeration value="dollars" />
              </xs:restriction>
            </xs:simpleType>
          </xs:attribute>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
</xs:schema>

Globally defined attribute type

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:simpleType name="currencyType">
    <xs:restriction base="xs:string">
      <xs:enumeration value="pounds" />
      <xs:enumeration value="euros" />
      <xs:enumeration value="dollars" />
    </xs:restriction>
  </xs:simpleType>

  <xs:element name="price">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="xs:decimal">
          <xs:attribute name="currency" type="currencyType"/>
        </xs:extension>
      </xs:simpleContent>
    </xs:complexType>
  </xs:element>
</xs:schema>

Notes

• As commented by @Paul, these do change the content type of price from xs:string to xs:decimal, but this is not strictly necessary and was not the real problem.
• As answered by @user998692, you could separate out the definition of currency, and you could change to xs:decimal, but this too was not the real problem.

The real problem was that xs:complexType cannot directly have a xs:extension as a child in XSD; xs:simpleContent is needed first.

A related matter (that wasn't asked but may have confused other answers):

How could price be restricted given that it has an attribute?

In this case, a separate, global definition of priceType would be needed; it is not possible to do this with only local type definitions.

      <xs:maxInclusive value="99999.99"/>  
    </xs:restriction>  
  </xs:simpleType>

  <xs:element name="price">
    <xs:complexType>
      <xs:simpleContent>
        <xs:extension base="priceType">

Enter SQL*Plus with:

sqlplus /nolog

And then:

connect sys@<SID> AS sysdba

According to this : we can write this help function :

    public static int convertBinaryToDecimal(String str) {
        int result = 0;
        for (int i = 0; i < str.length(); i++) {
            int value = Character.getNumericValue(str.charAt(i));
            result = result * 2 + value;
        }
        return result;
    }

See the timeseries documentation. It includes a list of offsets (and 'anchored' offsets), and a section about resampling.

Note that there isn't a list of all the different how options, because it can be any NumPy array function and any function that is available via groupby dispatching can be passed to how by name.

An other solution is to use the response.status function. This will give you the http status wich is returned by the ajax call.

function checkHttpStatus(url) {     
    $.ajax({
        type: "GET",
        data: {},
        url: url,
        error: function(response) {
            alert(url + " returns a " + response.status);
        }, success() {
            alert(url + " Good link");
        }
    });
}

After days trying to find the answer, I finally found

display: table;

There was surprisingly very little information available online about how to actually getting it to work, even here, so on to the "How":

To use this fantastic piece of code, you need to think back to when tables were the only real way to structure HTML, namely the syntax. To get a table with 2 rows and 3 columns, you'd have to do the following:

<table>
    <tr>
        <td></td>
        <td></td>
        <td></td>
    </tr>
    <tr>
        <td></td>
        <td></td>
        <td></td>
    </tr>
</table>

Similarly to get CSS to do it, you'd use the following:

HTML

<div id="table">
    <div class="tr">
        <div class="td"></div>
        <div class="td"></div>
        <div class="td"></div>
    </div>
    <div class="tr">
        <div class="td"></div>
        <div class="td"></div>
        <div class="td"></div>
    </div>
</div>

CSS

#table{ 
    display: table; 
}
.tr{ 
    display: table-row; 
}
.td{ 
    display: table-cell; }

As you can see in the JSFiddle example below, the divs in the 3rd column have no content, yet are respecting the auto height set by the text in the first 2 columns. WIN!

http://jsfiddle.net/blyzz/1djs97yv/1/

It's worth noting that display: table; does not work in IE6 or 7 (thanks, FelipeAls), so depending on your needs with regards to browser compatibility, this may not be the answer that you are seeking.

QUESTION:

What does => mean?

ANSWER:

=> Is the symbol we humans decided to use to separate "Key" => "Value" pairs in Associative Arrays.

ELABORATING:

To understand this, we have to know what Associative Arrays are. The first thing that comes up when a conventional programmer thinks of an array (in PHP) would be something similar to:

$myArray1 = array(2016, "hello", 33);//option 1

$myArray2 = [2016, "hello", 33];//option 2

$myArray3 = [];//option 3
$myArray3[] = 2016; 
$myArray3[] = "hello"; 
$myArray3[] = 33;

Where as, if we wanted to call the array in some later part of the code, we could do:

echo $myArray1[1];// output: hello
echo $myArray2[1];// output: hello
echo $myArray3[1];// output: hello

So far so good. However, as humans, we might find it hard to remember that index [0] of the array is the value of the year 2016, index [1] of the array is a greetings, and index [2] of the array is a simple integer value. The alternative we would then have is to use what is called an Associative Array. An Associative array has a few differences from a Sequential Array (which is what the previous cases were since they increment the index used in a predetermined sequence, by incrementing by 1 for each following value).

Differences (between a sequential and associative array):

• Durring the declaration of an Associative Array, you don't only include the value of what you want to put in the array, but you also put the index value (called the key) which you want to use when calling the array in later parts of the code. The following syntax is used during it's declaration: "key" => "value".

• When using the Associative Array, the key value would then be placed inside the index of the array to retrieve the desired value.

For instance:

$myArray1 = array( 
    "Year" => 2016, 
    "Greetings" => "hello", 
    "Integer_value" => 33);//option 1

$myArray2 = [ 
    "Year" =>  2016, 
    "Greetings" => "hello", 
    "Integer_value" => 33];//option 2

$myArray3 = [];//option 3
$myArray3["Year"] = 2016; 
$myArray3["Greetings"] = "hello"; 
$myArray3["Integer_value"] = 33;

And now, to receive the same output as before, the key value would be used in the arrays index:

echo $myArray1["Greetings"];// output: hello
echo $myArray2["Greetings"];// output: hello
echo $myArray3["Greetings"];// output: hello

FINAL POINT:

So from the above example, it is pretty easy to see that the => symbol is used to express the relationship of an Associative Array between each of the key and value pairs in an array DURING the initiation of the values within the array.

The problem happened because I was trying to bind a HTML element before it was created.

My script was loaded on top of the HTML and it needs to be loaded at the bottom of my HTML code.

I have recently written a plugin that does exactly that - jquery.initialize

You use it the same way as .each function

$(".some-element").initialize( function(){
    $(this).css("color", "blue"); 
});

The difference from .each is - it takes your selector, in this case .some-element and wait for new elements with this selector in the future, if such element will be added, it will be initialized too.

In our case initialize function just change element color to blue. So if we'll add new element (no matter if with ajax or even F12 inspector or anything) like:

$("<div/>").addClass('some-element').appendTo("body"); //new element will have blue color!

Plugin will init it instantly. Also plugin makes sure one element is initialized only once. So if you add element, then .detach() it from body and then add it again, it will not be initialized again.

$("<div/>").addClass('some-element').appendTo("body").detach()
    .appendTo(".some-container");
//initialized only once

Plugin is based on MutationObserver - it will work on IE9 and 10 with dependencies as detailed on the readme page.

You can find the number of characters using system function LEN. i.e.

SELECT LEN(Column) FROM TABLE

My simple fix to stop it putting speech marks around numeric values...

while($r = mysql_fetch_assoc($rs)){
    while($elm=each($r))
    {
        if(is_numeric($r[$elm["key"]])){
                    $r[$elm["key"]]=intval($r[$elm["key"]]);
        }
    }
    $rows[] = $r;
}   

From man clock:

The clock() function returns an approximation of processor time used by the program.

So there is no indication you should treat it as milliseconds. Some standards require precise value of CLOCKS_PER_SEC, so you could rely on it, but I don't think it is advisable. Second thing is that, as @unwind stated, it is not float/double. Man times suggests that will be an int. Also note that:

this function will return the same value approximately every 72 minutes

And if you are unlucky you might hit the moment it is just about to start counting from zero, thus getting negative or huge value (depending on whether you store the result as signed or unsigned value).

This:

printf("\n\n%6.3f", stop);

Will most probably print garbage as treating any int as float is really not defined behaviour (and I think this is where most of your problem comes). If you want to make sure you can always do:

printf("\n\n%6.3f", (double) stop);

Though I would rather go for printing it as long long int at first:

printf("\n\n%lldf", (long long int) stop);

import { Component, Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'timePipe'
})
export class TimeValuePipe implements PipeTransform {

  transform(value: any, args?: any): any {
   var hoursMinutes = value.split(/[.:]/);
  var hours = parseInt(hoursMinutes[0], 10);
  var minutes = hoursMinutes[1] ? parseInt(hoursMinutes[1], 10) : 0;
  console.log('hours ', hours);
  console.log('minutes ', minutes/60);
  return (hours + minutes / 60).toFixed(2);
  }
}
@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  name = 'Angular';
  order = [
    {
      "order_status": "Still at Shop",
      "order_id": "0:02"
    },
    {
      "order_status": "On the way",
      "order_id": "02:29"
    },
    {
      "order_status": "Delivered",
      "order_id": "16:14"
    },
     {
      "order_status": "Delivered",
      "order_id": "07:30"
    }
  ]
}

Invoke this module in App.Module.ts file.

You can configure your Lambda function to pull in additional code and content in the form of layers. A layer is a ZIP archive that contains libraries, a custom runtime, or other dependencies. With layers, you can use libraries in your function without needing to include them in your deployment package. Layers let you keep your deployment package small, which makes development easier.

-pattern_type glob

This great option makes it easier to select the images in many cases.

Slideshow video with one image per second

ffmpeg -framerate 1 -pattern_type glob -i '*.png' \
  -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4

Add some music to it, cutoff when the presumably longer audio when the images end:

ffmpeg -framerate 1 -pattern_type glob -i '*.png' -i audio.ogg \
  -c:a copy -shortest -c:v libx264 -r 30 -pix_fmt yuv420p out.mp4

Here are two demos on YouTube:

• https://www.youtube.com/watch?v=grV64VE1U6c
• https://www.youtube.com/watch?v=_6D05gCWh_I

Be a hippie and use the Theora patent-unencumbered video format:

ffmpeg -framerate 1 -pattern_type glob -i '*.png' -i audio.ogg \
  -c:a copy -shortest -c:v libtheora -r 30 -pix_fmt yuv420p out.ogg

Your images should of course be sorted alphabetically, typically as:

0001-first-thing.jpg
0002-second-thing.jpg
0003-and-third.jpg

and so on.

I would also first ensure that all images to be used have the same aspect ratio, possibly by cropping them with imagemagick or nomacs beforehand, so that ffmpeg will not have to make hard decisions. In particular, the width has to be divisible by 2, otherwise conversion fails with: "width not divisible by 2".

Normal speed video with one image per frame at 30 FPS

ffmpeg -framerate 30 -pattern_type glob -i '*.png' \

It is cool to observe how much the video compresses the image sequence way better than ZIP as it is able to compress across frames with specialized algorithms:

# Convert all to PNG for consistency.
# https://unix.stackexchange.com/questions/29869/converting-multiple-image-files-from-jpeg-to-pdf-format
# Hardlink the ones that are already PNG.
mkdir -p png
mogrify -format png -path png orig/*.jpg
ln -P orig/*.png png

Now we have a quick look at all image sizes to decide on the final aspect ratio:

identify png/*

which outputs:

png/1.png PNG 557x495 557x495+0+0 8-bit sRGB 653KB 0.000u 0:00.000
png/2.png PNG 664x800 664x800+0+0 8-bit sRGB 853KB 0.000u 0:00.000
png/3.png PNG 544x680 544x680+0+0 8-bit sRGB 442KB 0.000u 0:00.000
png/4.png PNG 207x238 207x238+0+0 8-bit sRGB 76.8KB 0.000u 0:00.000
png/5.png PNG 450x600 450x600+0+0 8-bit sRGB 627KB 0.000u 0:00.000

so the classic 480p (640x480 == 4/3) aspect ratio seems appropriate.

Do one conversion with minimal resizing to make widths even (TODO automate for any width, here I just manually looked at identify output and reduced width and height by one):

mkdir -p raw
convert png/1.png -resize 556x494 raw/1.png
ln -P png/2.png png/3.png png/4.png png/5.png raw
ffmpeg -framerate 1 -pattern_type glob -i 'raw/*.png' -i orig/audio.ogg -c:v libx264 -c:a copy -shortest -r 30 -pix_fmt yuv420p raw.mp4

This produces terrible output, because as seen from:

ffprobe raw.mp4

ffmpeg just takes the size of the first image, 556x494, and then converts all others to that exact size, breaking their aspect ratio.

Now let's convert the images to the target 480p aspect ratio automatically by cropping as per ImageMagick: how to minimally crop an image to a certain aspect ratio?

mkdir -p auto
mogrify -path auto -geometry 640x480^ -gravity center -crop 640x480+0+0 png/*.png
ffmpeg -framerate 1 -pattern_type glob -i 'auto/*.png' -i orig/audio.ogg -c:v libx264 -c:a copy -shortest -r 30 -pix_fmt yuv420p auto.mp4

So now, the aspect ratio is good, but inevitably some cropping had to be done, which kind of cut up interesting parts of the images.

The other option is to pad with black background to have the same aspect ratio as shown at: Resize to fit in a box and set background to black on "empty" part

mkdir -p black
ffmpeg -framerate 1 -pattern_type glob -i 'black/*.png' -i orig/audio.ogg -c:v libx264 -c:a copy -shortest -r 30 -pix_fmt yuv420p black.mp4

Generally speaking though, you will ideally be able to select images with the same or similar aspect ratios to avoid those problems in the first place.

About the CLI options

Note however that despite the name, -glob this is not as general as shell Glob patters, e.g.: -i '*' fails: https://trac.ffmpeg.org/ticket/3620 (apparently because filetype is deduced from extension).

-r 30 makes the -framerate 1 video 30 FPS to overcome bugs in players like VLC for low framerates: VLC freezes for low 1 FPS video created from images with ffmpeg Therefore it repeats each frame 30 times to keep the desired 1 image per second effect.

Next steps

You will also want to:

• cut up the part of the audio that you want before joining it: Cutting the videos based on start and end time using ffmpeg

  ffmpeg -i in.mp3 -ss 03:10 -to 03:30 -c copy out.mp3
  

TODO: learn to cut and concatenate multiple audio files into the video without intermediate files, I'm pretty sure it's possible:

• ffmpeg cut and concat single command line
• https://video.stackexchange.com/questions/21315/concatenating-split-media-files-using-concat-protocol
• https://superuser.com/questions/587511/concatenate-multiple-wav-files-using-single-command-without-extra-file

Tested on

ffmpeg 3.4.4, vlc 3.0.3, Ubuntu 18.04.

USE update_attribute instead of update_attributes

Updates a single attribute and saves the record without going through the normal validation procedure.

if a.update_attribute('state', a.state)

Note:- 'update_attribute' update only one attribute at a time from the code given in question i think it will work for you.

.....

$("#testID #testID2").removeClass("test2").addClass("test3");

Because you have assigned an id to img too, you can simply do this too:

$("#testID2").removeClass("test2").addClass("test3");

And finally, you can do this too:

$("#testID img").removeClass("test2").addClass("test3");

A file ending in .o is an object file. The compiler creates an object file for each source file, before linking them together, into the final executable.

You need to ensure that any code that modifies the HTTP headers is executed before the headers are sent. This includes statements like session_start(). The headers will be sent automatically when any HTML is output.

Your problem here is that you're sending the HTML ouput at the top of your page before you've executed any PHP at all.

Move the session_start() to the top of your document :

<?php    session_start(); ?> <html> <head> <title>PHP SDK</title> </head> <body> <?php require_once 'src/facebook.php';    // more PHP code here. 

Eclipse is defaulting to Java 1.5 and you have classes implementing interface methods (which in Java 1.6 can be annotated with @Override, but in Java 1.5 can only be applied to methods overriding a superclass method).

Go to your project/IDE preferences and set the Java compiler level to 1.6 and also make sure you select JRE 1.6 to execute your program from Eclipse.

Note that you can use the Polynomial class directly to do the fitting and return a Polynomial instance.

from numpy.polynomial import Polynomial

p = Polynomial.fit(x, y, 4)
plt.plot(*p.linspace())

p uses scaled and shifted x values for numerical stability. If you need the usual form of the coefficients, you will need to follow with

pnormal = p.convert(domain=(-1, 1))

If your modulus / divisor is a known constant, and you care about performance, see this and this. A multiplicative inverse is even possible for loop-invariant values that aren't known until runtime, e.g. see https://libdivide.com/ (But without JIT code-gen, that's less efficient than hard-coding just the steps necessary for one constant.)

Never use div for known powers of 2: it's much slower than and for remainder, or right-shift for divide. Look at C compiler output for examples of unsigned or signed division by powers of 2, e.g. on the Godbolt compiler explorer. If you know a runtime input is a power of 2, use lea eax, [esi-1] ; and eax, edi or something like that to do x & (y-1). Modulo 256 is even more efficient: movzx eax, cl has zero latency on recent Intel CPUs (mov-elimination), as long as the two registers are separate.

In the simple/general case: unknown value at runtime

The DIV instruction (and its counterpart IDIV for signed numbers) gives both the quotient and remainder. For unsigned, remainder and modulus are the same thing. For signed idiv, it gives you the remainder (not modulus) which can be negative:
e.g. -5 / 2 = -2 rem -1. x86 division semantics exactly match C99's % operator.

DIV r32 divides a 64-bit number in EDX:EAX by a 32-bit operand (in any register or memory) and stores the quotient in EAX and the remainder in EDX. It faults on overflow of the quotient.

Unsigned 32-bit example (works in any mode)

mov eax, 1234          ; dividend low half
mov edx, 0             ; dividend high half = 0.  prefer  xor edx,edx

mov ebx, 10            ; divisor can be any register or memory

div ebx       ; Divides 1234 by 10.
        ; EDX =   4 = 1234 % 10  remainder
        ; EAX = 123 = 1234 / 10  quotient

In 16-bit assembly you can do div bx to divide a 32-bit operand in DX:AX by BX. See Intel's Architectures Software Developer’s Manuals for more information.

Normally always use xor edx,edx before unsigned div to zero-extend EAX into EDX:EAX. This is how you do "normal" 32-bit / 32-bit => 32-bit division.

For signed division, use cdq before idiv to sign-extend EAX into EDX:EAX. See also Why should EDX be 0 before using the DIV instruction?. For other operand-sizes, use cbw (AL->AX), cwd (AX->DX:AX), cdq (EAX->EDX:EAX), or cqo (RAX->RDX:RAX) to set the top half to 0 or -1 according to the sign bit of the low half.

div / idiv are available in operand-sizes of 8, 16, 32, and (in 64-bit mode) 64-bit. 64-bit operand-size is much slower than 32-bit or smaller on current Intel CPUs, but AMD CPUs only care about the actual magnitude of the numbers, regardless of operand-size.

Note that 8-bit operand-size is special: the implicit inputs/outputs are in AH:AL (aka AX), not DL:AL. See 8086 assembly on DOSBox: Bug with idiv instruction? for an example.

Signed 64-bit division example (requires 64-bit mode)

   mov    rax,  0x8000000000000000   ; INT64_MIN = -9223372036854775808
   mov    ecx,  10           ; implicit zero-extension is fine for positive numbers

   cqo                       ; sign-extend into RDX, in this case = -1 = 0xFF...FF
   idiv   rcx
       ; quotient  = RAX = -922337203685477580 = 0xf333333333333334
       ; remainder = RDX = -8                  = 0xfffffffffffffff8

Limitations / common mistakes

div dword 10 is not encodeable into machine code (so your assembler will report an error about invalid operands).

Unlike with mul/imul (where you should normally use faster 2-operand imul r32, r/m32 or 3-operand imul r32, r/m32, imm8/32 instead that don't waste time writing a high-half result), there is no newer opcode for division by an immediate, or 32-bit/32-bit => 32-bit division or remainder without the high-half dividend input.

Division is so slow and (hopefully) rare that they didn't bother to add a way to let you avoid EAX and EDX, or to use an immediate directly.

div and idiv will fault if the quotient doesn't fit into one register (AL / AX / EAX / RAX, the same width as the dividend). This includes division by zero, but will also happen with a non-zero EDX and a smaller divisor. This is why C compilers just zero-extend or sign-extend instead of splitting up a 32-bit value into DX:AX.

And also why INT_MIN / -1 is C undefined behaviour: it overflows the signed quotient on 2's complement systems like x86. See Why does integer division by -1 (negative one) result in FPE? for an example of x86 vs. ARM. x86 idiv does indeed fault in this case.

The x86 exception is #DE - divide exception. On Unix/Linux systems, the kernel delivers a SIGFPE arithmetic exception signal to processes that cause a #DE exception. (On which platforms does integer divide by zero trigger a floating point exception?)

For div, using a dividend with high_half < divisor is safe. e.g. 0x11:23 / 0x12 is less than 0xff so it fits in an 8-bit quotient.

Extended-precision division of a huge number by a small number can be implemented by using the remainder from one chunk as the high-half dividend (EDX) for the next chunk. This is probably why they chose remainder=EDX quotient=EAX instead of the other way around.

you could also use $location.$$search.yourparameter

Try this

#include <stdio.h>

struct context;

struct funcptrs{
  void (*func0)(struct context *ctx);
  void (*func1)(void);
};

struct context{
    struct funcptrs fps;
}; 

void func1 (void) { printf( "1\n" ); }
void func0 (struct context *ctx) { printf( "0\n" ); }

void getContext(struct context *con){
    con->fps.func0 = func0;  
    con->fps.func1 = func1;  
}

int main(int argc, char *argv[]){
 struct context c;
   c.fps.func0 = func0;
   c.fps.func1 = func1;
   getContext(&c);
   c.fps.func0(&c);
   getchar();
   return 0;
}

Replying in particular to:

You can create a new interface in the networking panel, based on an existing interface, but it will not act as a real fully functional interface (if the original interface is inactive, then the derived one is also inactive).

This can be achieved using a Tun/Tap device as suggested by psv141, and manipulating the /Library/Preferences/SystemConfiguration/preferences.plist file to add a NetworkService based on either a tun or tap interface. Mac OS X will not allow the creation of a NetworkService based on a virtual network interface, but one can directly manipulate the preferences.plist file to add the NetworkService by hand. Basically you would open the preferences.plist file in Xcode (or edit the XML directly, but Xcode is likely to be more fool-proof), and copy the configuration from an existing Ethernet interface. The place to create the new NetworkService is under "NetworkServices", and if your Mac has an Ethernet device the NetworkService profile will also be under this property entry. The Ethernet entry can be copied pretty much verbatim, the only fields you would actually be changing are:

• UUID
• UserDefinedName
• IPv4 configuration and set the interface to your tun or tap device (i.e. tun0 or tap0).
• DNS server if needed.

Then you would also manipulate the particular Location you want this NetworkService for (remember Mac OS X can configure all network interfaces dependent on your "Location"). The default location UUID can be obtained in the root of the PropertyList as the key "CurrentSet". After figuring out which location (or set) you want, expand the Set property, and add entries under Global/IPv4/ServiceOrder with the UUID of the new NetworkService. Also under the Set property you need to expand the Service property and add the UUID here as a dictionary with one String entry with key __LINK__ and value as the UUID (use the other interfaces as an example).

After you have modified your preferences.plist file, just reboot, and the NetworkService will be available under SystemPreferences->Network. Note that we have mimicked an Ethernet device so Mac OS X layer of networking will note that "a cable is unplugged" and will not let you activate the interface through the GUI. However, since the underlying device is a tun/tap device and it has an IP address, the interface will become active and the proper routing will be added at the BSD level.

As a reference this is used to do special routing magic.

In case you got this far and are having trouble, you have to create the tun/tap device by opening one of the devices under /dev/. You can use any program to do this, but I'm a fan of good-old-fashioned C myself:

#include <stdio.h>
#include <fcntl.h>
#include <unistd.h>
int main()
{
   int fd = open("/dev/tun0", O_RDONLY);
   if (fd < 0)
   {
      printf("Failed to open tun/tap device. Are you root? Are the drivers installed?\n");
      return -1;
   }
   while (1)
   {
      sleep(100000);
   }
   return 0;
}

If you are talking about debugging to see the assembly code, the easiest way is Debug->Windows->Disassembly (or Alt-8). This will let you step into a called function and stay in Disassembly.

I've seen projects implemented using a number of different approaches, each have their merits and drawbacks.

• One did it in the config file (not my favourite)
• One did it using a database - this worked pretty well, but was a pain in the you know what to maintain.
• One used resource files the way you're suggesting and I have to say it was my favourite approach.
• The most basic one did it using an include file full of strings - ugly.

I'd say the resource method you've chosen makes a lot of sense. It would be interesting to see other people's answers too as I often wonder if there's a better way of doing things like this. I've seen numerous resources that all point to the using resources method, including one right here on SO.

You have to modify your server side code, as given below

public class CorsResponseFilter implements ContainerResponseFilter {
@Override
public void filter(ContainerRequestContext requestContext,   ContainerResponseContext responseContext)
    throws IOException {
        responseContext.getHeaders().add("Access-Control-Allow-Origin","*");
        responseContext.getHeaders().add("Access-Control-Allow-Methods", "GET, POST, DELETE, PUT");

  }
}

import java.util.ArrayList;
import java.util.Random;
public class shuffle {
    public static void main(String[] args) {
        int a[] =  {1,2,3,4,5,6,7,8,9};
         ArrayList b = new ArrayList();
       int i=0,q=0;
       Random rand = new Random();

       while(a.length!=b.size())
       {
           int l = rand.nextInt(a.length);
//this is one option to that but has a flaw on 0
//           if(a[l] !=0)
//           {
//                b.add(a[l]);
//               a[l]=0;
//               
//           }
//           
// this works for every no. 
                if(!(b.contains(a[l])))
                {
                    b.add(a[l]);
                }



       }

//        for (int j = 0; j <b.size(); j++) {
//            System.out.println(b.get(j));
//            
//        }
System.out.println(b);
    }

}

For those using the very popular Json.Net project from Newtonsoft the task is trivial:

using Newtonsoft.Json;

....
var s = JsonConvert.ToString(@"a\b");
Console.WriteLine(s);
....

This code prints:

"a\\b"

That is, the resulting string value contains the quotes as well as the escaped backslash.

Find your stopped container id

docker ps -a

Commit the stopped container:

This command saves modified container state into a new image user/test_image

docker commit $CONTAINER_ID user/test_image

Start/run with a different entry point:

docker run -ti --entrypoint=sh user/test_image

Entrypoint argument description: https://docs.docker.com/engine/reference/run/#/entrypoint-default-command-to-execute-at-runtime

Note:

Steps above just start a stopped container with the same filesystem state. That is great for a quick investigation. But environment variables, network configuration, attached volumes and other staff is not inherited, you should specify all these arguments explicitly.

Steps to start a stopped container have been borrowed from here: (last comment) https://github.com/docker/docker/issues/18078

To late for the original asker of the question, but with SQL Server 2008 R2 this is now possible:

Set the property "Pagebreak" on the tablix or table or other element to force a new tab, and then set the property "Pagename" on both the element before the pagebreak and the element after the pagebreak. These names will appear on the tabs when the report is exported to Excel.

I know this is a little off the OPs original request but I came across this while looking for a way to use Invoke-WebRequest against a site requiring basic authentication.

The difference is, I did not want to record the password in the script. Instead, I wanted to prompt the script runner for credentials for the site.

Here's how I handled it

$creds = Get-Credential

$basicCreds = [pscredential]::new($Creds.UserName,$Creds.Password)

Invoke-WebRequest -Uri $URL -Credential $basicCreds

The result is the script runner is prompted with a login dialog for the U/P then, Invoke-WebRequest is able to access the site with those credentials. This works because $Creds.Password is already an encrypted string.

I hope this helps someone looking for a similar solution to the above question but without saving the username or PW in the script

The Git GUI for Windows has a window-based application that allows you to paste in locations for ssh keys and repo url etc:

https://gitforwindows.org/

In Angular, <a>s are directives. As such, if you have an empty href or no href, Angular will call event.preventDefault.

From the source:

    element.on('click', function(event){
      // if we have no href url, then don't navigate anywhere.
      if (!element.attr(href)) {
        event.preventDefault();
      }
    });

Here's a plnkr demonstrating the missing href scenario.

You can use:

 a.delete(a[0])   
 a.delete_at 0

Both can work

I'd love to post this as a comment to Tendayi Mawushe's answer, but I'm afraid there is not enough space ;)

This is the relevant part from the Apache Commons UrlValidator source:

/**
 * This expression derived/taken from the BNF for URI (RFC2396).
 */
private static final String URL_PATTERN =
        "/^(([^:/?#]+):)?(//([^/?#]*))?([^?#]*)(\\?([^#]*))?(#(.*))?/";
//         12            3  4          5       6   7        8 9

/**
 * Schema/Protocol (ie. http:, ftp:, file:, etc).
 */
private static final int PARSE_URL_SCHEME = 2;

/**
 * Includes hostname/ip and port number.
 */
private static final int PARSE_URL_AUTHORITY = 4;

private static final int PARSE_URL_PATH = 5;

private static final int PARSE_URL_QUERY = 7;

private static final int PARSE_URL_FRAGMENT = 9;

You can easily build your own validator from there.

Request class doesn't offer a method that would return exactly what you need. But you can easily get it by concatenating results of 2 other methods:

echo (Request::getPathInfo() . (Request::getQueryString() ? ('?' . Request::getQueryString()) : '');

Here's an alternative solution:

>>> import pyexcel as pe
>>> text="""1,2,3
... a,b,c
... d,e,f"""
>>> s = pe.load_from_memory('csv', text)
>>> s
Sheet Name: csv
+---+---+---+
| 1 | 2 | 3 |
+---+---+---+
| a | b | c |
+---+---+---+
| d | e | f |
+---+---+---+
>>> s.to_array()
[[u'1', u'2', u'3'], [u'a', u'b', u'c'], [u'd', u'e', u'f']]

Here's the documentation

I faced the same issue. But i resolved it by changing my port numbers to different one.

I also had a config file at /etc/my.cnf that I needed to delete on my Mac OS X Snow Leopard install

I know it's an old question, but I needed this solution too, and I acme with another solution.

I used an entrypoint.sh to execute the following line, and define a variable with the actual hostname for that instance:

HOST=`hostname --fqdn`

Then, I used it across my entrypoint script:

echo "Value: $HOST"

Hope this helps

A little late but this could help: http://webdesign.tutsplus.com/tutorials/how-to-make-responsive-scrollable-panels-with-flexbox--cms-23269

Basically you need to put html,body to height: 100%; and wrap all your content into a <div class="wrap"> <!-- content --> </div>

CSS:

html, body {
  height: 100%;
}

.wrap {
  height: 100vh;
  display: flex;
}

Worked for me. Hope it helps

int? here = (list.ElementAtOrDefault(2) != 0 ? list[2]:(int?) null);

When putting resource files in another location is not the best solution you can use:

<build>
  <resources>
    <resource>
      <directory>src/main/java</directory>
      <excludes>
        <exclude>**/*.java</exclude>
      </excludes>
    </resource>
  </resources>
<build>

For example when resources files (e.g. jaxb.properties) goes deep inside packages along with Java classes.

The thing that works best for me when that happens is :

1. Create a new eclipse project(JAVA)

2. Take your source file (contents of the src folder!!!) and drag from finder and drop into the src folder in eclipse IDE

3. Make sure you add your external jars and stuff and tada you're done!!

Don't think anyone mentioned the overhead in exception handling - takes additional resources to load up and process the exception so unless its a true app killing or process stopping event (going forward would cause more harm than good) I would opt for passing back a value the calling environment could interpret as it sees fit.

I realize this question was about creating a plugin, but since the new Jenkins 2 Pipeline builds use Groovy, I found myself here while trying to figure out how to read a file from a workspace in a Pipeline build. So maybe I can help someone like me out in the future.

Turns out it's very easy, there is a readfile step, and I should have rtfm:

env.WORKSPACE = pwd()
def version = readFile "${env.WORKSPACE}/version.txt"

Although not specific to the answer, this error mostly occurs when you mistakenly using a JavaScript expression inside a JavaScript context using {}

For example

let x=5;

export default function App(){ return( {x} ); };

Correct way to do this would be

let x=5;
export default function App(){ return( x ); };

In Swift:

override func viewDidLayoutSubviews() {
      super.viewDidLayoutSubviews()
      self.tableView.contentInset = UIEdgeInsets(top: 108, left: 0, bottom: 0, right: 0)
}

Maybe a bit more lazy:

a = [1,2,3,4]
b = [2,7]

print any((True for x in a if x in b))

Use the retainAll() method of Set:

Set<String> s1;
Set<String> s2;
s1.retainAll(s2); // s1 now contains only elements in both sets

If you want to preserve the sets, create a new set to hold the intersection:

Set<String> intersection = new HashSet<String>(s1); // use the copy constructor
intersection.retainAll(s2);

The javadoc of retainAll() says it's exactly what you want:

Retains only the elements in this set that are contained in the specified collection (optional operation). In other words, removes from this set all of its elements that are not contained in the specified collection. If the specified collection is also a set, this operation effectively modifies this set so that its value is the intersection of the two sets.

I had this keep coming up as a newbie and found that present loads modal views that can be dismissed but switching to root controller is best if you don't need to show a modal.

I was using this

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc  = storyboard?.instantiateViewController(withIdentifier: "MainAppStoryboard") as! TabbarController
present(vc, animated: false, completion: nil)

Using this instead with my tabController:

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let view = storyboard.instantiateViewController(withIdentifier: "MainAppStoryboard") as UIViewController
let appDelegate = UIApplication.shared.delegate as! AppDelegate
//show window
appDelegate.window?.rootViewController = view

Just adjust to a view controller if you need to switch between multiple storyboard screens.

You want this:

function validate() {
    var acc = document.getElementsByName('acc')[0].value;
    var pass = document.getElementsByName('pass')[0].value;

    alert (acc);
}

Check if your OS is Windows 7 Service Pack 1.. use "winver" to verify.

For those of you who came here looking for the actual Unicode character values for a keycode, like I did, here is a function for that. For instance, given the right arrow unicode keycode this will output the visible string \u001B\u005B\u0043

function toUnicode(theString) {
    var unicodeString = '';
    for (var i = 0; i < theString.length; i++) {
        var theUnicode = theString.charCodeAt(i).toString(16).toUpperCase();
        while (theUnicode.length < 4) {
            theUnicode = '0' + theUnicode;
        }
        theUnicode = '\\u' + theUnicode;
        unicodeString += theUnicode;
    }
    return unicodeString;
}

Ruby doesn't like that you are assigning the constant inside of a method because it risks re-assignment. Several SO answers before me give the alternative of assigning it outside of a method--but in the class, which is a better place to assign it.

I think the question was about to open a local file directly instead of downloading a local file to the download folder and open the file in the download folder, which seems not possible in Chrome, except some add-on mentioned above.

My workaround would be to right click -> Copy the link location Windows + R and paste the link there and Enter It will go to the file directly.

For those who are having trouble indenting phpstorm here I have a tip and I hope they help ...

First you have to go to file-> settings-> keymap-> select-> windows.

If they are on the windows machine. If you are on mac and choose macos.

 private void CheckIfPalindrome(string str) 
        {
            //place string in array of chars
            char[] array = str.ToCharArray(); 
            int length = array.Length -1 ;
            Boolean palindrome =true;
            for (int i = 0; i <= length; i++)//go through the array
            {
                if (array[i] != array[length])//compare if the char in the same positions are the same eg "tattarrattat" will compare array[0]=t with array[11] =t if are not the same stop the for loop
                {
                    MessageBox.Show("not");
                    palindrome = false;
                    break;

                }
                else //if they are the same make length smaller by one and do the same 
                {                   
                  length--;
                }

            }
            if (palindrome) MessageBox.Show("Palindrome"); 

        }

Deep copy literally performs a deep copy. It means, that if your class has some fields that are references, their values will be copied, not references themselves. If, for example you have two instances of a class, A & B with fields of reference type, and perform a deep copy, changing a value of that field in A won't affect a value in B. And vise-versa. Things are different with shallow copy, because only references are copied, therefore, changing this field in a copied object would affect the original object.

What type of a copy does a copy constructor does?

It is implementation - dependent. This means that there are no strict rules about that, you can implement it like a deep copy or shallow copy, however as far as i know it is a common practice to implement a deep copy in a copy constructor. A default copy constructor performs a shallow copy though.

exampleData=

        const json1 = [
            {id: 1, test: 1},
            {id: 2, test: 2},
            {id: 3, test: 3},
            {id: 4, test: 4},

            {id: 4, test: 7},
            {id: 5, test: 8},
            {id: 6, test: 9},
            {id: 7, test: 10}
        ];

        const finalData1 = json1.concat(json2).reduce(function (index, obj) {
            index[obj.id] = Object.assign({}, obj, index[obj.id]);
            return index;
        }, []).filter(function (res, obj) {
            return obj;
        });

example2=

        let hashData = new Map();

        json1.concat(json2).forEach(function (obj) {
            hashData.set(obj.id, Object.assign(hashData.get(obj.id) || {}, obj))
        });

        const finalData2 = Array.from(hashData.values());

I recommend second example , it is faster.

When a and b are 1-dimensional sequences, numpy.cov(a,b)[0][1] is equivalent to your cov(a,b).

The 2x2 array returned by np.cov(a,b) has elements equal to

cov(a,a)  cov(a,b)

cov(a,b)  cov(b,b)

(where, again, cov is the function you defined above.)

It looks like your Google Play registration payment didn’t process. This can happen sometimes if a card has expired, the credit card or credit card verification (CVC) number was entered incorrectly, or if your billing address doesn't match the address in your Google Payments account.

Here’s how you can find the details of your transaction:

1. Sign in to your Google Payments account at https://payments.google.com.

2. On the left menu, select the “Subscriptions and services” page.

3. On the “Other purchase activity” card, click View purchases.

4. Click the “Google Play” registration transaction to see your payment method.

5. You can click “Payment methods” on the left menu if you need to edit the addresses on your Google Payments account.

To add a new credit or debit card to your account, you can follow the instructions on the Google Payments Help Center (https://support.google.com/payments/answer/6220309).

Custom filter is more appropriate, then you can use it anywhere in the project

js file

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

myApp.filter('utcdate', ['$filter','$locale', function($filter, $locale){

    return function (input, format) {
        if (!angular.isDefined(format)) {
            format = $locale['DATETIME_FORMATS']['medium'];
        }

        var date = new Date(input);
        var d = new Date()
        var _utc = new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(),  date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds());
        return $filter('date')(_utc, format)
    };

 }]);

in template

<p>This will convert UTC time to local time<p>
<span>{{dateTimeInUTC | utcdate :'MMM d, y h:mm:ss a'}}</span>

You can see my answer to this in my answer to another question.

In Windows, the global install path is actually in your user's profile directory

• %USERPROFILE%\AppData\Roaming\npm
• %USERPROFILE%\AppData\Roaming\npm-cache
• WARNING: If you're doing timed events or other automation as a different user, make sure you run npm install as that user. Some modules/utilities should be installed globally.
• INSTALLER BUGS: You may have to create these directories or add the ...\npm directory to your users path yourself.

To change the "global" location for all users to a more appropriate shared global location %ALLUSERSPROFILE%\(npm|npm-cache) (do this as an administrator):

• create an [NODE_INSTALL_PATH]\etc\ directory
  • this is needed before you try npm config --global ... actions
• create the global (admin) location(s) for npm modules
  • C:\ProgramData\npm-cache - npm modules will go here
  • C:\ProgramData\npm - binary scripts for globally installed modules will go here
  • C:\ProgramData\npm\node_modules - globally installed modules will go here
  • set the permissions appropriately
    • administrators: modify
    • authenticated users: read/execute
• Set global configuration settings (Administrator Command Prompt)
  • npm config --global set prefix "C:\ProgramData\npm"
  • npm config --global set cache "C:\ProgramData\npm-cache"
• Add C:\ProgramData\npm to your System's Path environment variable

If you want to change your user's "global" location to %LOCALAPPDATA%\(npm|npm-cache) path instead:

• Create the necessary directories
  • C:\Users\YOURNAME\AppData\Local\npm-cache - npm modules will go here
  • C:\Users\YOURNAME\AppData\Local\npm - binary scripts for installed modules will go here
  • C:\Users\YOURNAME\AppData\Local\npm\node_modules - globally installed modules will go here
• Configure npm
  • npm config set prefix "C:\Users\YOURNAME\AppData\Local\npm"
  • npm config set cache "C:\Users\YOURNAME\AppData\Local\npm-cache"
• Add the new npm path to your environment's PATH.
  • setx PATH "%PATH%;C:\Users\YOURNAME\AppData\Local\npm"

It's a good practice if you need them. It's also a good practice is they make sense, so future coders can understand what you're doing.

But generally, no it's not a good practice to attach 10 class names to an object because most likely whatever you're using them for, you could accomplish the same thing with far fewer classes. Probably just 1 or 2.

To qualify that statement, javascript plugins and scripts may append far more classnames to do whatever it is they're going to do. Modernizr for example appends anywhere from 5 - 25 classes to your body tag, and there's a very good reason for it. jQuery UI appends lots of classnames when you use one of the widgets in that library.

Schema behaves seem like a parent object as seen in OOP world. so it's not a database itself. maybe this link is useful.

But, In MySQL, the two are equivalent. The keyword DATABASE or DATABASES can be replaced with SCHEMA or SCHEMAS wherever it appears. Examples:

• CREATE DATABASE <=> CREATE SCHEMA
• SHOW DATABASES <=> SHOW SCHEMAS

Documentation of MySQL

SCHEMA & DATABASE terms are something DBMS dependent.

A Table is a set of data elements (values) that is organized using a model of vertical columns (which are identified by their name) and horizontal rows. A database contains one or more(usually) Tables . And you store your data in these tables. The tables may be related with one another(See here).

Since Bootstrap v4.1 you can add table-borderless to your table, see official documentation:

<table class='table table-borderless'>

I'm using EasyPHP in making my Thesis about Content Management System. So far, this tool is very good and easy to use.

From a mysql datetime/timestamp format:

var dateStr="2011-08-03 09:15:11"; //returned from mysql timestamp/datetime field
var a=dateStr.split(" ");
var d=a[0].split("-");
var t=a[1].split(":");
var date = new Date(d[0],(d[1]-1),d[2],t[0],t[1],t[2]);

Did research for this at school and as Justing already said. The specification is far from ready, so it wil probably take a while before HTML5 is being supported in editor. Though browsers are busy implementing the parts from the specification that are good enough to be used.

Best you can do is follow blogs, tutorials and other articles on the internet and experiment with developing in HTML5 yourself.

EDIT: Just found an Visual Studio 2008/2010 Plug-in here

You should use PDO Prepare

From the link:

Calling PDO::prepare() and PDOStatement::execute() for statements that will be issued multiple times with different parameter values optimizes the performance of your application by allowing the driver to negotiate client and/or server side caching of the query plan and meta information, and helps to prevent SQL injection attacks by eliminating the need to manually quote the parameters.

While performance issues are valid the real reasons in practice that you should avoid storing images in a database are for database management reasons. Your database will grow very rapidly and databases cost much more than simple file storage. Database backups and restores are much more expensive and time-consuming than file backup restores. In a pinch, you can restore a smaller database much more quickly than one bloated with images. Compare 1 TB of file storage on Azure to a 1 TB database and you'll see the vast difference in cost.

Give a class .border-lb and give this CSS

In Year 2019, we can use Javascript's ES6 Spread syntax to do it concisely and efficiently

data = [...data, {"label": 2, "value": 13}]

Examples

var data = [_x000D_
      {"label" : "1", "value" : 12},_x000D_
      {"label" : "1", "value" : 12},_x000D_
      {"label" : "1", "value" : 12},_x000D_
    ];_x000D_
    _x000D_
data = [...data, {"label" : "2", "value" : 14}] _x000D_
console.log(data)

For your case (i know it was in 2011), we can do it with map() & forEach() like below

var lab = ["1","2","3","4"];_x000D_
var val = [42,55,51,22];_x000D_
_x000D_
//Using forEach()_x000D_
var data = [];_x000D_
val.forEach((v,i) => _x000D_
   data= [...data, {"label": lab[i], "value":v}]_x000D_
)_x000D_
_x000D_
//Using map()_x000D_
var dataMap = val.map((v,i) => _x000D_
 ({"label": lab[i], "value":v})_x000D_
)_x000D_
_x000D_
console.log('data: ', data);_x000D_
console.log('dataMap : ', dataMap);

1. Check for your configuration files by running the aforementioned command: sudo nginx -t.

2. Check for port conflicts. For instance, if apache2 (ps waux | grep apache2) or any other service is using the same ports configured for nginx (say port 80) the service will not start and will fail silently (err... the cousin of my friend had this problem...)

Have you tried to set isUserInteractionEnabled to true on the tripDetails label? This should work.

There is no way for CSS/HTML to know if the image is broken link, so you are going to have to use JavaScript no matter what

But here is a minimal method for either hiding the image, or replacing the source with a backup.

<img src="Error.src" onerror="this.style.display='none'"/>

or

<img src="Error.src" onerror="this.src='fallback-img.jpg'"/>

Update

You can apply this logic to multiple images at once by doing something like this:

document.addEventListener("DOMContentLoaded", function(event) {_x000D_
   document.querySelectorAll('img').forEach(function(img){_x000D_
   img.onerror = function(){this.style.display='none';};_x000D_
   })_x000D_
});

<img src="error.src">_x000D_
<img src="error.src">_x000D_
<img src="error.src">_x000D_
<img src="error.src">

Update 2

For a CSS option see michalzuber's answer below. You can't hide the entire image, but you change how the broken icon looks.

Use replaceAll instead of replace

str = str.replaceAll("X,"");

This should give you the desired answer.

Try using SCP on Windows to transfer files, you can download SCP from Putty's website. Then try running:

In JavaScript this always refers to the “owner” of the function we're executing, or rather, to the object that a function is a method of. When we define our faithful function doSomething() in a page, its owner is the page, or rather, the window object (or global object) of JavaScript.

How does the "this" keyword work?

might be surprised to know.. its PHP. read all about it here

I encapsulated the logic in the following helper method.

public class JpaResultHelper {
    public static Object getSingleResultOrNull(Query query){
        List results = query.getResultList();
        if (results.isEmpty()) return null;
        else if (results.size() == 1) return results.get(0);
        throw new NonUniqueResultException();
    }
}

I had the same problem.

If you are using a Mac, you will need to empty the Cache (Option+?+E) and reload the page in addition to restarting the app (and of course changing the path in index.html).

There are many answers to the question, but I felt there is a need for some really simple answer clearly comparing the two. Here's the discussion I made up when a user searches for a movie name in an MVP and MVC app:

User: Click click …

View: Who’s that? [MVP|MVC]

User: I just clicked on the search button …

View: Ok, hold on a sec … . [MVP|MVC]

( View calling the Presenter|Controller … ) [MVP|MVC]

View: Hey Presenter|Controller, a User has just clicked on the search button, what shall I do? [MVP|MVC]

Presenter|Controller: Hey View, is there any search term on that page? [MVP|MVC]

View: Yes,… here it is … “piano” [MVP|MVC]

Presenter: Thanks View,… meanwhile I’m looking up the search term on the Model, please show him/her a progress bar [MVP|MVC]

( Presenter|Controller is calling the Model … ) [MVP|MVC]

Presenter|Controller: Hey Model, Do you have any match for this search term?: “piano” [MVP|MVC]

Model: Hey Presenter|Controller, let me check … [MVP|MVC]

( Model is making a query to the movie database … ) [MVP|MVC]

( After a while ... )

-------------- This is where MVP and MVC start to diverge ---------------

Model: I found a list for you, Presenter, here it is in JSON “[{"name":"Piano Teacher","year":2001},{"name":"Piano","year":1993}]” [MVP]

Model: There is some result available, Controller. I have created a field variable in my instance and filled it with the result. It's name is "searchResultsList" [MVC]

(Presenter|Controller thanks Model and gets back to the View) [MVP|MVC]

Presenter: Thanks for waiting View, I found a list of matching results for you and arranged them in a presentable format: ["Piano Teacher 2001","Piano 1993"]. Please show it to the user in a vertical list. Also please hide the progress bar now [MVP]

Controller: Thanks for waiting View, I have asked Model about your search query. It says it has found a list of matching results and stored them in a variable named "searchResultsList" inside its instance. You can get it from there. Also please hide the progress bar now [MVC]

View: Thank you very much Presenter [MVP]

View: Thank you "Controller" [MVC] (Now the View is questioning itself: How should I present the results I get from the Model to the user? Should the production year of the movie come first or last...? Should it be in a vertical or horizontal list? ...)

In case you're interested, I have been writing a series of articles dealing with app architectural patterns (MVC, MVP, MVVP, clean architecture, ...) accompanied by a Github repo here. Even though the sample is written for android, the underlying principles can be applied to any medium.

Yeah it's possible.

Button myBtn = (Button)findViewById(R.id.myButtonId);
myBtn.requestFocus();

or in XML

<Button ...><requestFocus /></Button>

Important Note: The button widget needs to be focusable and focusableInTouchMode. Most widgets are focusable but not focusableInTouchMode by default. So make sure to either set it in code

myBtn.setFocusableInTouchMode(true);

or in XML

android:focusableInTouchMode="true"

Approach: 1

Given original string format: 2019/03/04 00:08:48

you can use

updated_df = df['timestamp'].astype('datetime64[ns]')

The result will be in this datetime format: 2019-03-04 00:08:48

Approach: 2

updated_df = df.astype({'timestamp':'datetime64[ns]'})

If you could not set your application autostart you can try to paste this code to manifest

<requestedExecutionLevel  level="asInvoker" uiAccess="false" />

or delete manifest I had found it in my application

I tried all possible options but result is zero. Finally i found correct solution which is helpful for me. Just go to disable Instant Run Go to File -> Settings -> Build,Execution, Deployment -> Instant Run -> Uncheck the checkbox for instant run. Run your app once and this apk file work properly..

You can get the original host from X-Forwarded-For header field.

If you have sklearn isntalled, a simple alternative is to use sklearn.metrics.auc

This computes the area under the curve using the trapezoidal rule given arbitrary x, and y array

import numpy as np
from sklearn.metrics import auc

dx = 5
xx = np.arange(1,100,dx)
yy = np.arange(1,100,dx)

print('computed AUC using sklearn.metrics.auc: {}'.format(auc(xx,yy)))
print('computed AUC using np.trapz: {}'.format(np.trapz(yy, dx = dx)))

both output the same area: 4607.5

the advantage of sklearn.metrics.auc is that it can accept arbitrarily-spaced 'x' array, just make sure it is ascending otherwise the results will be incorrect

I think you need to get some fundamentals right. With the examples above you have created tensors (multi dimensional array). But for tensor flow to really work you have to initiate a "session" and run your "operation" in the session. Notice the word "session" and "operation". You need to know 4 things to work with tensorflow:

1. tensors
2. Operations
3. Sessions
4. Graphs

Now from what you wrote out you have given the tensor, and the operation but you have no session running nor a graph. Tensor (edges of the graph) flow through graphs and are manipulated by operations (nodes of the graph). There is default graph but you can initiate yours in a session.

When you say print , you only access the shape of the variable or constant you defined.

So you can see what you are missing :

 with tf.Session() as sess:     
           print(sess.run(product))
           print (product.eval())

Hope it helps!

Pure html is not able to do what you want. My suggestion would be to write a simple javascript function to do the roudning for you.

private String message;
private ScreenManager s;


//Here is an example of code to add the keyListener() as suggested; modify 
public void init(){
Window w = s.getFullScreenWindow();
w.addKeyListener(this);

public void keyPressed(KeyEvent e){
    int keyCode = e.getKeyCode();
        if(keyCode == KeyEvent.VK_F5)
            message = "Pressed: " + KeyEvent.getKeyText(keyCode);
}

svn info -r HEAD

This will give you the latest revision number at the head of your repository.

There are some nice blog posts about integrating subversion numbers into your build script:

• Getting Subversion Revision in Ant
• Automatic Build Sub-Versioning in Xcode

Below was the similar kind of error i encountered

The model backing the 'PsnlContext' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).

I added the below section in the Application Start event of the Global.asax to solve the error

Database.SetInitializer (null);

This fixed the issue

Serialization

Serialization is the process of converting an object or a set of objects graph into a stream, it is a byte array in the case of binary serialization

Uses of Serialization

1. To save the state of an object into a file, database etc. and use it latter.
2. To send an object from one process to another (App Domain) on the same machine and also send it over wire to a process running on another machine.
3. To create a clone of the original object as a backup while working on the main object.
4. A set of objects can easily be copied to the system’s clipboard and then pasted into the same or another application

Below are some useful custom attributes that are used during serialization of an object

[Serializable] -> It is used when we mark an object’s serializable [NonSerialized] -> It is used when we do not want to serialize an object’s field. [OnSerializing] -> It is used when we want to perform some action while serializing an object [OnSerialized] -> It is used when we want to perform some action after serialized an object into stream.

Below is the example of serialization

[Serializable]
    internal class DemoForSerializable
    {
        internal string Fname = string.Empty;
        internal string Lname = string.Empty;

        internal Stream SerializeToMS(DemoForSerializable demo)
        {
            DemoForSerializable objSer = new DemoForSerializable();
            MemoryStream ms = new MemoryStream();
            BinaryFormatter bf = new BinaryFormatter();
            bf.Serialize(ms, objSer);
            return ms;
        }

        [OnSerializing]
        private void OnSerializing(StreamingContext context) {
            Fname = "sheo";
            Lname = "Dayal";
        }
        [OnSerialized]
        private void OnSerialized(StreamingContext context)
        {
       // Do some work after serialized object
        }

    }

Here is the calling code

class Program
    {
        string fname = string.Empty;
        string Lname = string.Empty; 

       static void Main(string[] args)
        {
            DemoForSerializable demo = new DemoForSerializable();

            Stream ms = demo.SerializeToMS(demo);
            ms.Position = 0;

            DemoForSerializable demo1 = new BinaryFormatter().Deserialize(ms) as DemoForSerializable;

            Console.WriteLine(demo1.Fname);
            Console.WriteLine(demo1.Lname);
            Console.ReadLine();
        }

    }

We have this problem and to solve

Create a script file called to-utf8.sh

#!/bin/bash
TO="UTF-8"; FILE=$1
FROM=$(file -i $FILE | cut -d'=' -f2)
if [[ $FROM = "binary" ]]; then
 echo "Skipping binary $FILE..."
 exit 0
fi
iconv -f $FROM -t $TO -o $FILE.tmp $FILE; ERROR=$?
if [[ $ERROR -eq 0 ]]; then
  echo "Converting $FILE..."
  mv -f $FILE.tmp $FILE
else
  echo "Error on $FILE"
fi

Set the executable bit

chmod +x to-utf8.sh

Do a conversion

./to-utf8.sh MyFile.txt

If you want to convert all files under a folder, do

find /your/folder/here | xargs -n 1 ./to-utf8.sh

Hope it's help.

You need to commit or destroy any unsaved changes before you switch branch.

Git won't let you switch branch if it means unsaved changes would be removed.

yes stale element error is thrown when (taking your scenario) you have defined locator strategy to click on 'Add Item' first and then when you close the pop up the page gets refreshed hence the reference defined for 'Add Item' is lost in the memory so to overcome this you have to redefine the locator strategy for 'Add Item' again

understand it with a dummy code

// clicking on view details 
driver.findElement(By.id("")).click();
// closing the pop up 
driver.findElement(By.id("")).click();


// and when you try to click on Add Item
driver.findElement(By.id("")).click();
// you get stale element exception as reference to add item is lost 
// so to overcome this you have to re identify the locator strategy for add item 
// Please note : this is one of the way to overcome stale element exception 

// Step 1 please add a universal wait in your script like below 
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS); // just after you have initiated browser

rows.RemoveAt(rows.Count - 1);

Create a Directive with the show and size attributes ( you can add more also )

    app.directive('loader',function(){
    return {
    restrict:'EA',
    scope:{
        show : '@',
      size : '@'
    },
    template : '<div class="loader-container"><div class="loader" ng-if="show" ng-class="size"></div></div>'
  }
})

and in html use as

 <loader show="{{loader1}}" size="sm"></loader>

In the show variable pass true when any promise is running and make that false when request is completed. Active demo - Angular Loader directive example demo in JsFiddle

the correct answer is @chepner's

EXT=java
for i in *.${EXT}; do
    ...
done

however, here's a small trick to check whether a filename has a given extensions:

EXT=java
for i in *; do
    if [ "${i}" != "${i%.${EXT}}" ];then
        echo "I do something with the file $i"
    fi
done

If you have background on that element, then, adding padding would be useless.

So, in this case, you can use background-clip: content-box; or outline-offset

Explanation: If you use wrapper, then it would be simple to separate the background from border. But if you want to style the same element, which has a background, no matter how much padding you would add, there would be no space between background and border, unless you use background-clip or outline-offset

you can swipe the key and the value. For example

        String[] k = {"Elena", "Thomas", "Hamilton", "Suzie", "Phil"};
        int[] v = {341, 273, 278, 329, 445};
        TreeMap<Integer,String>a=new TreeMap();
        for (int i = 0; i < k.length; i++) 
           a.put(v[i],k[i]);            
        System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());
        a.remove(a.firstEntry().getKey());
        System.out.println(a.firstEntry().getValue()+"\t"+a.firstEntry().getKey());

HTML:

<tr>
    <th>Language</th>
    <th>Skill Level</th>
    <th>&nbsp;</th>
</tr>

CSS:

tr, th {
    padding: 10px;
    text-align: center;
}

The time.time() function returns the number of seconds since the epoch, as seconds. Note that the "epoch" is defined as the start of January 1st, 1970 in UTC. So the epoch is defined in terms of UTC and establishes a global moment in time. No matter where you are "seconds past epoch" (time.time()) returns the same value at the same moment.

Here is some sample output I ran on my computer, converting it to a string as well.

Python 2.7.3 (default, Apr 24 2012, 00:00:54) 
[GCC 4.7.0 20120414 (prerelease)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import time
>>> ts = time.time()
>>> print ts
1355563265.81
>>> import datetime
>>> st = datetime.datetime.fromtimestamp(ts).strftime('%Y-%m-%d %H:%M:%S')
>>> print st
2012-12-15 01:21:05
>>>

The ts variable is the time returned in seconds. I then converted it to a string using the datetime library making it a string that is human readable.

Started a jsFiddle here.

It seems the horizontal alignment works with a text-align : center. Still trying to get the vertical align to work; might have to use absolute positioning and something like top: 50% or a pre-calculated padding from the top.

Best Solution is go to File -> Sync Project With Gradle Files

I hope this helped

Apparently this would be possible in settings.gradle with something like this.

rootProject.name = 'someName'
gradle.rootProject {
    it.sourceCompatibility = '1.7'
}

I recently received advice that a project property can be set by using a closure which will be called later when the Project is available.

I experienced this today. The value in Config was the updated one but the application would return the older value, stop and starting the solution did nothing.

So I cleared the .Net Temp folder.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

It shouldn't create bugs but to be safe close your solution down first. Clear the Temporary ASP.NET Files then load up your solution.

My issue was sorted.

Have a look at iconv() or mb_convert_encoding(). Just by the way: why don't utf8_encode() and utf8_decode() work for you?

utf8_decode — Converts a string with ISO-8859-1 characters encoded with UTF-8 to single-byte ISO-8859-1

utf8_encode — Encodes an ISO-8859-1 string to UTF-8

So essentially

$utf8 = 'ÄÖÜ'; // file must be UTF-8 encoded
$iso88591_1 = utf8_decode($utf8);
$iso88591_2 = iconv('UTF-8', 'ISO-8859-1', $utf8);
$iso88591_2 = mb_convert_encoding($utf8, 'ISO-8859-1', 'UTF-8');

$iso88591 = 'ÄÖÜ'; // file must be ISO-8859-1 encoded
$utf8_1 = utf8_encode($iso88591);
$utf8_2 = iconv('ISO-8859-1', 'UTF-8', $iso88591);
$utf8_2 = mb_convert_encoding($iso88591, 'UTF-8', 'ISO-8859-1');

all should do the same - with utf8_en/decode() requiring no special extension, mb_convert_encoding() requiring ext/mbstring and iconv() requiring ext/iconv.

below will work with any previously pushed revision, not only HEAD

for abbreviated revision hash:

git log -1 --pretty=format:%h

for long revision hash:

git log -1 --pretty=format:%H

Your Problem were the slice declarations in your data structs (except for Track, they shouldn't be slices...). This was compounded by some rather goofy fieldnames in the fetched json file, which can be fixed via structtags, see godoc.

The code below parsed the json successfully. If you've further questions, let me know.

package main

import "fmt"
import "net/http"
import "io/ioutil"
import "encoding/json"

type Tracks struct {
    Toptracks Toptracks_info
}

type Toptracks_info struct {
    Track []Track_info
    Attr  Attr_info `json: "@attr"`
}

type Track_info struct {
    Name       string
    Duration   string
    Listeners  string
    Mbid       string
    Url        string
    Streamable Streamable_info
    Artist     Artist_info   
    Attr       Track_attr_info `json: "@attr"`
}

type Attr_info struct {
    Country    string
    Page       string
    PerPage    string
    TotalPages string
    Total      string
}

type Streamable_info struct {
    Text      string `json: "#text"`
    Fulltrack string
}

type Artist_info struct {
    Name string
    Mbid string
    Url  string
}

type Track_attr_info struct {
    Rank string
}

func perror(err error) {
    if err != nil {
        panic(err)
    }
}

func get_content() {
    url := "http://ws.audioscrobbler.com/2.0/?method=geo.gettoptracks&api_key=c1572082105bd40d247836b5c1819623&format=json&country=Netherlands"

    res, err := http.Get(url)
    perror(err)
    defer res.Body.Close()

    decoder := json.NewDecoder(res.Body)
    var data Tracks
    err = decoder.Decode(&data)
    if err != nil {
        fmt.Printf("%T\n%s\n%#v\n",err, err, err)
        switch v := err.(type){
            case *json.SyntaxError:
                fmt.Println(string(body[v.Offset-40:v.Offset]))
        }
    }
    for i, track := range data.Toptracks.Track{
        fmt.Printf("%d: %s %s\n", i, track.Artist.Name, track.Name)
    }
}

}

In my case, I updated one of my libraries in my android project.

I'm using Reservoir as my cache storage solution: https://github.com/anupcowkur/Reservoir

I went from:

compile 'com.anupcowkur:reservoir:2.1'

To:

compile 'com.anupcowkur:reservoir:3.1.0'

The library author must have removed the commons-io library from the repo so my app no longer worked.

I had to manually include the commons-io by adding this onto gradle:

compile 'commons-io:commons-io:2.5'

https://mvnrepository.com/artifact/commons-io/commons-io/2.5

Change

var svg   = document.documentElement;

to

var svg = document.createElementNS("http://www.w3.org/2000/svg", "svg");

so that you create a SVG element.

For the link to be an hyperlink, simply add a href attribute :

h.setAttributeNS(null, 'href', 'http://www.google.com');

Demonstration

I don't know about best (simplest? fastest? most readable?), but one way would be:

dict(zip([1, 2, 3, 4], [a, b, c, d]))

Just put this blur view on the imageView. Here is an example in Objective-C:

UIVisualEffect *blurEffect;
blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];

UIVisualEffectView *visualEffectView;
visualEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];

visualEffectView.frame = imageView.bounds;
[imageView addSubview:visualEffectView];

and Swift:

var visualEffectView = UIVisualEffectView(effect: UIBlurEffect(style: .Light))    

visualEffectView.frame = imageView.bounds

imageView.addSubview(visualEffectView)

Such kind of error normally happens when you try using functions like php_info() wrongly.

<?php 
     php_info(); // 500 error
     phpinfo(); // Works correctly
?>

A close look at your code will be better.

There's tonnes of them on regexlib

Or you can use the Central Maven Repository with the Servlet 3.0 API which is also provided for the Tomcat Server 7.0.X

    <dependency>
        <groupId>org.apache.tomcat</groupId>
        <artifactId>tomcat-servlet-api</artifactId>
        <version>7.0.21</version>
        <scope>provided</scope>
    </dependency>

from here: http://repo2.maven.org/maven2/org/apache/tomcat/tomcat-servlet-api/7.0.21/

Alternative solution:

>>> from datetime import date
>>> (date(2012, 3, 1) - date(2012, 2, 1)).days

In MS Windows the temporary directory is set by the environment variable TEMP. In XP, the temporary directory was set per-user as Local Settings\Temp.

If you change your TEMP environment variable to C:\temp, then you get the same when you run :

System.out.println(System.getProperty("java.io.tmpdir"));

Yes, you can set a timeout of say 2 seconds on each and every key up event which will fire an ajax request. You can also store the XHR method and abort it on subsequent key press events so that you save bandwith even more. Here's something I've written for an autocomplete script of mine.

var timer;
var x;

$(".some-input").keyup(function () {
    if (x) { x.abort() } // If there is an existing XHR, abort it.
    clearTimeout(timer); // Clear the timer so we don't end up with dupes.
    timer = setTimeout(function() { // assign timer a new timeout 
        x = $.getJSON(...); // run ajax request and store in x variable (so we can cancel)
    }, 2000); // 2000ms delay, tweak for faster/slower
});

Hope this helps,

I would do it using a for loop as shown below :

def determine_period(universe_array):
    tmp = universe_array
    for period in xrange(1, 13):
        tmp = apply_rules(tmp)
        if numpy.array_equal(tmp, universe_array):
            return period
    return 0

I had the same problem and this is how i done it.

remove comment in httpd.conf (apache configuration file):

LoadModule rewrite_module modules/mod_rewrite.so 

Using private API:

@objc func tableViewDidFinishReload(_ tableView: UITableView) {
    print(#function)
    cellsAreLoaded = true
}

Using public API:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    // cancel the perform request if there is another section
    [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(tableViewDidLoadRows:) object:tableView];

    // create a perform request to call the didLoadRows method on the next event loop.
    [self performSelector:@selector(tableViewDidLoadRows:) withObject:tableView afterDelay:0];

    return [self.myDataSource numberOfRowsInSection:section];
}

// called after the rows in the last section is loaded
-(void)tableViewDidLoadRows:(UITableView*)tableView{
    self.cellsAreLoaded = YES;
}

A possible better design is to add the visible cells to a set, then when you need to check if the table is loaded you can instead do a for loop around this set, e.g.

var visibleCells = Set<UITableViewCell>()

override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    visibleCells.insert(cell)
}

override func tableView(_ tableView: UITableView, didEndDisplaying cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    visibleCells.remove(cell)
}

// example property you want to show on a cell that you only want to update the cell after the table is loaded. cellForRow also calls configure too for the initial state.
var count = 5 {
    didSet {
        for cell in visibleCells {
            configureCell(cell)
        }
    }
}

When navigating between two separate directories and copying files back and forth, I do this:

cd /some/where/long
src=`pwd`
cd /other/where/long
dest=`pwd`

cp $src/foo $dest

command completion will work by expanding the variable, so you can use tab completion to specify a file you're working with.
