From the "View" menu, select "Workspaces". You'll see all of the workspaces you've created. Select the workspaces you want to delete and click "Edit" -> "Delete Workspace", or right-click and select "Delete Workspace". If the workspace is "locked" to prevent changes, you'll get an error message.

To unlock the workspace, click "Edit" (or right-click and click "Edit Workspace") to pull up the workspace editor, uncheck the "locked" checkbox, and save your changes. You can delete the workspace once it's unlocked.

In my experience, the workspace will continue to be shown in the drop-down list until you click on it, at which point p4v will figure out you've deleted it and remove it from the list.

Apparently GitHub now offer git training courses to companies. Quoth their blog post about it:

I’ve been down to the Google campus a number of times in the last few weeks helping to train the Androids there in Git. I was asked by Shawn Pearce (you may know him from his Git and EGit/JGit glory – he is the hero that takes over maintanance when Junio is out of town) to come in to help him train the Google engineers working on Andriod in transitioning from Perforce to Git, so Android could be shared with the masses. I can tell you I was more than happy to do it.

[…]

Logical Awesome is now officially offering this type of custom training service to all companies, where we can help your organization with training and planning if you are thinking about switching to Git as well.

Emphasis mine.

Rollback... will prompt you to select a folder to rollback, ie, it will work on specific folders, and you can rollback to labels or changlists or dates. Back out works on the files in specific changelists.

How to declare the various functions?

Compile, Controller, Pre-link & Post-link

If one is to use all four function, the directive will follow this form:

myApp.directive( 'myDirective', function () {
    return {
        restrict: 'EA',
        controller: function( $scope, $element, $attrs, $transclude ) {
            // Controller code goes here.
        },
        compile: function compile( tElement, tAttributes, transcludeFn ) {
            // Compile code goes here.
            return {
                pre: function preLink( scope, element, attributes, controller, transcludeFn ) {
                    // Pre-link code goes here
                },
                post: function postLink( scope, element, attributes, controller, transcludeFn ) {
                    // Post-link code goes here
                }
            };
        }
    };  
});

Notice that compile returns an object containing both the pre-link and post-link functions; in Angular lingo we say the compile function returns a template function.

Compile, Controller & Post-link

If pre-link isn't necessary, the compile function can simply return the post-link function instead of a definition object, like so:

myApp.directive( 'myDirective', function () {
    return {
        restrict: 'EA',
        controller: function( $scope, $element, $attrs, $transclude ) {
            // Controller code goes here.
        },
        compile: function compile( tElement, tAttributes, transcludeFn ) {
            // Compile code goes here.
            return function postLink( scope, element, attributes, controller, transcludeFn ) {
                    // Post-link code goes here                 
            };
        }
    };  
});

Sometimes, one wishes to add a compile method, after the (post) link method was defined. For this, one can use:

myApp.directive( 'myDirective', function () {
    return {
        restrict: 'EA',
        controller: function( $scope, $element, $attrs, $transclude ) {
            // Controller code goes here.
        },
        compile: function compile( tElement, tAttributes, transcludeFn ) {
            // Compile code goes here.

            return this.link;
        },
        link: function( scope, element, attributes, controller, transcludeFn ) {
            // Post-link code goes here
        }

    };  
});

Controller & Post-link

If no compile function is needed, one can skip its declaration altogether and provide the post-link function under the link property of the directive's configuration object:

myApp.directive( 'myDirective', function () {
    return {
        restrict: 'EA',
        controller: function( $scope, $element, $attrs, $transclude ) {
            // Controller code goes here.
        },
        link: function postLink( scope, element, attributes, controller, transcludeFn ) {
                // Post-link code goes here                 
        },          
    };  
});

No controller

In any of the examples above, one can simply remove the controller function if not needed. So for instance, if only post-link function is needed, one can use:

myApp.directive( 'myDirective', function () {
    return {
        restrict: 'EA',
        link: function postLink( scope, element, attributes, controller, transcludeFn ) {
                // Post-link code goes here                 
        },          
    };  
});

Why you just don't add a class to the string container and then replace the inner text ? Just like in this example.

HTML:

<div>
    <div>
        <p>
           <h1>
             <a class="swapText">lollipops</a>
           </h1>
        </p>
        <span class="swapText">lollipops</span>
    </div>
</div>
<p>
   <span class="lollipops">Hello, World!</span>
   <img src="/lollipops.jpg" alt="Cool image" />
</p>

jQuery:

$(document).ready(function() {
    $('.swapText').text("marshmallows");
});

Use strlen to get the length of a null-terminated string.

sizeof returns the length of the array not the string. If it's a pointer (char *s), not an array (char s[]), it won't work, since it will return the size of the pointer (usually 4 bytes on 32-bit systems). I believe an array will be passed or returned as a pointer, so you'd lose the ability to use sizeof to check the size of the array.

So, only if the string spans the entire array (e.g. char s[] = "stuff"), would using sizeof for a statically defined array return what you want (and be faster as it wouldn't need to loop through to find the null-terminator) (if the last character is a null-terminator, you will need to subtract 1). If it doesn't span the entire array, it won't return what you want.

An alternative to all this is actually storing the size of the string.

Bergi's solution works nicely when fs is promise based. You can use bluebird, fs-extra or fs-promise for this.

However, solution for node's native fs libary is as follows:

const result = await Promise.all(filePaths
    .map( async filePath => {
      const fileContents = await getAssetFromCache(filePath, async function() {

        // 1. Wrap with Promise    
        // 2. Return the result of the Promise
        return await new Promise((res, rej) => {
          fs.readFile(filePath, 'utf8', function(err, data) {
            if (data) {
              res(data);
            }
          });
        });
      });

      return fileContents;
    }));

Note: require('fs') compulsorily takes function as 3rd arguments, otherwise throws error:

TypeError [ERR_INVALID_CALLBACK]: Callback must be a function

I'm not familiar with python 3 yet, but it seems like urllib.request.urlopen().read() returns a byte object rather than string.

You might try to feed it into a StringIO object, or even do a str(response).

No, there is no "easy" way. Your best bet would be to do a loop where you first check each previous sibling, then move to the parent node and all of its previous siblings.

You'll need to break the selector into two, 1 to check if the current node could be the top level node in your selector, and 1 to check if it's descendants match.

Edit: This might as well be a plugin. You can use this with any selector in any HTML:

(function($) {
    $.fn.closestPrior = function(selector) {
        selector = selector.replace(/^\s+|\s+$/g, "");
        var combinator = selector.search(/[ +~>]|$/);
        var parent = selector.substr(0, combinator);
        var children = selector.substr(combinator);
        var el = this;
        var match = $();
        while (el.length && !match.length) {
            el = el.prev();
            if (!el.length) {
                var par = el.parent();
                // Don't use the parent - you've already checked all of the previous 
                // elements in this parent, move to its previous sibling, if any.
                while (par.length && !par.prev().length) {
                    par = par.parent();
                }
                el = par.prev();
                if (!el.length) {
                    break;
                }
            }
            if (el.is(parent) && el.find(children).length) {
                match = el.find(children).last();
            }
            else if (el.find(selector).length) {
                match = el.find(selector).last();
            }
        }
        return match;
    }
})(jQuery);

If you are using svn+ssh to connect to the repository then the only thing that authenticates you and authorizes you is your ssh credentials. EVERYTHING else is ignored. Your username will be logged in subversion exactly as it is established in your ssh connection. An excellent explanation of this is at jimmyg.org/blog/2007/subversion-over-svnssh-on-debian.html

Checking your linked site, you may include a script tag passing a ?var=desiredVarName parameter which will be set as a global variable containing the IP address:

<script type="text/javascript" src="http://l2.io/ip.js?var=myip"></script>
                                                      <!-- ^^^^ -->
<script>alert(myip);</script>

Demo

I believe I don't have to say that this can be easily spoofed (through either use of proxies or spoofed request headers), but it is worth noting in any case.

HTTPS support

In case your page is served using the https protocol, most browsers will block content in the same page served using the http protocol (that includes scripts and images), so the options are rather limited. If you have < 5k hits/day, the Smart IP API can be used. For instance:

<script>
var myip;
function ip_callback(o) {
    myip = o.host;
}
</script>
<script src="https://smart-ip.net/geoip-json?callback=ip_callback"></script>
<script>alert(myip);</script>

Demo

Edit: Apparently, this https service's certificate has expired so the user would have to add an exception manually. Open its API directly to check the certificate state: https://smart-ip.net/geoip-json

With back-end logic

The most resilient and simple way, in case you have back-end server logic, would be to simply output the requester's IP inside a <script> tag, this way you don't need to rely on external resources. For example:

PHP:

<script>var myip = '<?php echo $_SERVER['REMOTE_ADDR']; ?>';</script>

There's also a more sturdy PHP solution (accounting for headers that are sometimes set by proxies) in this related answer.

C#:

<script>var myip = '<%= Request.UserHostAddress %>';</script>

Laravel 5.2+ solution.

Model::getQuery()->delete();

Just grab underlying builder with table name and do whatever. Couldn't be any tidier than that.

Laravel 5.6 solution

\App\Model::query()->delete();

Tested and working!

I am not using a windows machine, I am on a linux platform. I ran across this executable-not-found issue in the context of using the python package pyAgrum for plotting bayesian networks. pyAgrum uses graphviz to plot the networks. I installed pyagrum and graphviz using the anaconda platform in a python 3.6.4 environment (i.e. conda install <package name>).

I found the executables in /conda/envs/<environment name>/bin directory. So, it was just a matter of getting my notebook kernel to find them.

If you import os, use the command os.environ['PATH'].split(os.pathsep) to see the executable paths in which your environment is looking. If the path containing your graphviz executables isn't in there, you can add it by doing the following: os.environ['PATH'] += os.pathsep + <path to executables>.

I imagine this solution will work outside of my context. The main downside to this solution is that you need to do it every time you restart the kernel.

To search google using API you should use Google Custom Search, scraping web page is not allowed

In java you can use CustomSearch API Client Library for Java

The maven dependency is:

<dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-customsearch</artifactId>
    <version>v1-rev57-1.23.0</version>
</dependency> 

Example code searching using Google CustomSearch API Client Library

public static void main(String[] args) throws GeneralSecurityException, IOException {

    String searchQuery = "test"; //The query to search
    String cx = "002845322276752338984:vxqzfa86nqc"; //Your search engine

    //Instance Customsearch
    Customsearch cs = new Customsearch.Builder(GoogleNetHttpTransport.newTrustedTransport(), JacksonFactory.getDefaultInstance(), null) 
                   .setApplicationName("MyApplication") 
                   .setGoogleClientRequestInitializer(new CustomsearchRequestInitializer("your api key")) 
                   .build();

    //Set search parameter
    Customsearch.Cse.List list = cs.cse().list(searchQuery).setCx(cx); 

    //Execute search
    Search result = list.execute();
    if (result.getItems()!=null){
        for (Result ri : result.getItems()) {
            //Get title, link, body etc. from search
            System.out.println(ri.getTitle() + ", " + ri.getLink());
        }
    }

}

As you can see you will need to request an api key and setup an own search engine id, cx.

Note that you can search the whole web by selecting "Search entire web" on basic tab settings during setup of cx, but results will not be exactly the same as a normal browser google search.

Currently (date of answer) you get 100 api calls per day for free, then google like to share your profit.

This is a huge topic, with answers from 3 lines of code to entire research magazines.

I will outline the most common such techniques and their results.

Comparing histograms

One of the simplest & fastest methods. Proposed decades ago as a means to find picture simmilarities. The idea is that a forest will have a lot of green, and a human face a lot of pink, or whatever. So, if you compare two pictures with forests, you'll get some simmilarity between histograms, because you have a lot of green in both.

Downside: it is too simplistic. A banana and a beach will look the same, as both are yellow.

OpenCV method: compareHist()

Template matching

A good example here matchTemplate finding good match. It convolves the search image with the one being search into. It is usually used to find smaller image parts in a bigger one.

Downsides: It only returns good results with identical images, same size & orientation.

OpenCV method: matchTemplate()

Feature matching

Considered one of the most efficient ways to do image search. A number of features are extracted from an image, in a way that guarantees the same features will be recognized again even when rotated, scaled or skewed. The features extracted this way can be matched against other image feature sets. Another image that has a high proportion of the features matching the first one is considered to be depicting the same scene.

Finding the homography between the two sets of points will allow you to also find the relative difference in shooting angle between the original pictures or the amount of overlapping.

There are a number of OpenCV tutorials/samples on this, and a nice video here. A whole OpenCV module (features2d) is dedicated to it.

Downsides: It may be slow. It is not perfect.

Over on the OpenCV Q&A site I am talking about the difference between feature descriptors, which are great when comparing whole images and texture descriptors, which are used to identify objects like human faces or cars in an image.

px ? Pixels

All of these answers seem to be incorrect. Contrary to intuition, in CSS the px is not pixels. At least, not in the simple physical sense.

Read this article from the W3C, EM, PX, PT, CM, IN…, about how px is a "magical" unit invented for CSS. The meaning of px varies by hardware and resolution. (That article is fresh, last updated 2014-10.)

My own way of thinking about it: 1 px is the size of a thin line intended by a designer to be barely visible.

To quote that article:

The px unit is the magic unit of CSS. It is not related to the current font and also not related to the absolute units. The px unit is defined to be small but visible, and such that a horizontal 1px wide line can be displayed with sharp edges (no anti-aliasing). What is sharp, small and visible depends on the device and the way it is used: do you hold it close to your eyes, like a mobile phone, at arms length, like a computer monitor, or somewhere in between, like a book? The px is thus not defined as a constant length, but as something that depends on the type of device and its typical use.

To get an idea of the appearance of a px, imagine a CRT computer monitor from the 1990s: the smallest dot it can display measures about 1/100th of an inch (0.25mm) or a little more. The px unit got its name from those screen pixels.

Nowadays there are devices that could in principle display smaller sharp dots (although you might need a magnifier to see them). But documents from the last century that used px in CSS still look the same, no matter what the device. Printers, especially, can display sharp lines with much smaller details than 1px, but even on printers, a 1px line looks very much the same as it would look on a computer monitor. Devices change, but the px always has the same visual appearance.

That article gives some guidance about using pt vs px vs em, to answer this Question.

Edited the config file and changed bare = true to bare = false

If this didn't work:

  <ImageView
    android:layout_gravity="center_horizontal"
    android:paddingTop="10px"
    android:paddingBottom="5px"
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"
    android:src="@android:drawable/divider_horizontal_bright" />

Try this raw View:

<View
    android:layout_width="fill_parent"
    android:layout_height="1dip"
    android:background="#000000" />

I got this error because I didn't create my own test suite correctly:

Here is how I did it correctly:

Put this in Foobar.java:

public class Foobar{
    public int getfifteen(){
        return 15;
    }
}

Put this in FoobarTest.java:

import static org.junit.Assert.*;
import junit.framework.JUnit4TestAdapter;
import org.junit.Test;
public class FoobarTest {
    @Test
    public void mytest() {
        Foobar f = new Foobar();

        assert(15==f.getfifteen());
    }
    public static junit.framework.Test suite(){
       return new JUnit4TestAdapter(FoobarTest.class);
    }
}

Download junit4-4.8.2.jar I used the one from here:

http://www.java2s.com/Code/Jar/j/Downloadjunit4jar.htm

Compile it:

javac -cp .:./libs/junit4-4.8.2.jar Foobar.java FoobarTest.java

Run it:

el@failbox /home/el $ java -cp .:./libs/* org.junit.runner.JUnitCore FoobarTest
JUnit version 4.8.2
.
Time: 0.009    
OK (1 test)

One test passed.

Since it's an external resource you'd need to go with JSONP because of the Same origin policy.
To do that you need to add the querystring parameter callback:

$.getJSON("http://myjsonsource?callback=?", function(data) {
    // Get the element with id summary and set the inner text to the result.
    $('#summary').text(data.result);
});

If you're talking about ASP.NET MVC then you should have a controller method that returns the following:

return Redirect("http://www.google.com");

Otherwise we need more info on the error you're getting in the redirect. I'd step through to make sure the url isn't empty.

Try JSMin, got C#, Java, C and other ports and readily available too.

Use java.util.regex.Pattern class's static method matches(regex, String obj)
regex : characters in lower and upper case & digits between 0-9
String obj : String object you want to check either it contain special character or not.

It returns boolean value true if only contain characters and numbers, otherwise returns boolean value false

Example.

String isin = "12GBIU34RT12";<br>
if(Pattern.matches("[a-zA-Z0-9]+", isin)<br>{<br>
   &nbsp; &nbsp; &nbsp; &nbsp;System.out.println("Valid isin");<br>
}else{<br>
   &nbsp; &nbsp; &nbsp; &nbsp;System.out.println("Invalid isin");<br>
}

After painful experimentation to find something faster than the accepted answer, I got this to work. It ran around 100x faster on the dataset I tried it on.

If someone knows a way to make this more elegant, by all means please modify my code. I couldn't find a way that works without setting the other columns you want to keep as the index and then resetting the index and re-naming the columns, but I'd imagine there's something else that works.

b = DataFrame(a.var1.str.split(',').tolist(), index=a.var2).stack()
b = b.reset_index()[[0, 'var2']] # var1 variable is currently labeled 0
b.columns = ['var1', 'var2'] # renaming var1

The correct statement should be :

SELECT
  student.firstname,
  student.lastname,
  exam.name,
  exam.date,
  grade.grade
FROM grade
  INNER JOIN student
    ON student.studentId = grade.fk_studentId
  INNER JOIN exam

A table is refered to other on the basis of the foreign key relationship defined. You should refer the ids properly if you wish the data to show as queried. So you should refer the id's to the proper foreign keys in the table rather than just on the id which doesn't define a proper relation

Here are a few ways to do it

INSERT INTO pxlot (realname,email,address,phone,status,regtime,ip) 
select '$realname','$email','$address','$phone','0','$dateTime','$ip' 
from SOMETABLEWITHTONSOFROWS LIMIT 3;

or

INSERT INTO pxlot (realname,email,address,phone,status,regtime,ip) 
select '$realname','$email','$address','$phone','0','$dateTime','$ip'
union all select '$realname','$email','$address','$phone','0','$dateTime','$ip'
union all select '$realname','$email','$address','$phone','0','$dateTime','$ip'

or

INSERT INTO pxlot (realname,email,address,phone,status,regtime,ip) 
values ('$realname','$email','$address','$phone','0','$dateTime','$ip')
,('$realname','$email','$address','$phone','0','$dateTime','$ip')
,('$realname','$email','$address','$phone','0','$dateTime','$ip')

 return $this->db->select('(CASE 
            enter code hereWHEN orderdetails.ProductID = 0   THEN dealmaster.deal_name
            WHEN orderdetails.DealID = 0 THEN products.name
            END) as product_name')

You can simply use | filter:yourFunction:arg

<div ng-repeat="group in groups | filter:weDontLike:group">...</div>

And in js

$scope.weDontLike = function(group) {
//here your condition/criteria
return !!group 
}

Try this:

import matplotlib as plt

after importing the file we can use matplotlib library but remember to use it as plt

df.plt(kind='line',figsize=(10,5))

after that the plot will be done and size increased. In figsize the 10 is for breadth and 5 is for height. Also other attributes can be added to the plot too.

This works for me:

pandas.factorize( ['B', 'C', 'D', 'B'] )[0]

Output:

[0, 1, 2, 0]

If SQL Server edition is 2005/2008, you can use DMVs to calculate the row count in a table:

-- Shows all user tables and row counts for the current database 
-- Remove is_ms_shipped = 0 check to include system objects 
-- i.index_id < 2 indicates clustered index (1) or hash table (0) 
SELECT o.name, 
 ddps.row_count 
FROM sys.indexes AS i 
 INNER JOIN sys.objects AS o ON i.OBJECT_ID = o.OBJECT_ID 
 INNER JOIN sys.dm_db_partition_stats AS ddps ON i.OBJECT_ID = ddps.OBJECT_ID 
 AND i.index_id = ddps.index_id 
WHERE i.index_id < 2 
 AND o.is_ms_shipped = 0 
ORDER BY o.NAME 

For SQL Server 2000 database engine, sysindexes will work, but it is strongly advised to avoid using it in future editions of SQL Server as it may be removed in the near future.

Sample code taken from: How To Get Table Row Counts Quickly And Painlessly

You can use <Text> like a container for your other text components. This is example:

...
<Text>
  <Text>This is a sentence</Text>
  <Text style={{fontWeight: "bold"}}> with</Text>
  <Text> one word in bold</Text>
</Text>
...

Here is an example.

I had the same problem and came across this post. Nothing worked. After randomly playing around, I found that <embed ........ play="false"> stopped it from playing automatically. I now have the problem that I can't get a controller to appear, so can't start the movie! :S

VMDK/VMX are VMWare file formats but you can use it with VirtualBox:

1. Create a new Virtual Machine and when asks for a hard disk choose "Use an existing hard disk"
2. Click on the "button with folder and green arrow image on the combo box right" which opens Virtual Media Manager, it looks like this (you can open it directly pressing CTRL+D on main window or in File > Virtual Media Manager menu)...
3. Then you can add the VMDK/VMX hard disk image and setup it for your virtual machine :)

@id/ and @android:id/ is not the same.

@id/ referencing ID in your application, @android:id/ referencing an item in Android platform.

Eclipse is wrong.

You have multiple columns named the same thing in your inner query, so the error is raised in the outer query. If you get rid of the outer query, it should run, although still be confusing:

SELECT DISTINCT
    coaches.id,
    people.*,
    users.*,
    coaches.*
FROM "COACHES"
    INNER JOIN people ON people.id = coaches.person_id
    INNER JOIN users ON coaches.person_id = users.person_id
    LEFT OUTER JOIN organizations_users ON organizations_users.user_id = users.id
WHERE
    rownum <= 25

It would be much better (for readability and performance both) to specify exactly what fields you need from each of the tables instead of selecting them all anyways. Then if you really need two fields called the same thing from different tables, use column aliases to differentiate between them.

There is a timeout on broken connections (i.e. due to network errors), which relies on the OS' TCP keepalive feature. By default on Linux, broken TCP connections are closed after ~2 hours (see sysctl net.ipv4.tcp_keepalive_time).

There is also a timeout on abandoned transactions, idle_in_transaction_session_timeout and on locks, lock_timeout. It is recommended to set these in postgresql.conf.

But there is no timeout for a properly established client connection. If a client wants to keep the connection open, then it should be able to do so indefinitely. If a client is leaking connections (like opening more and more connections and never closing), then fix the client. Do not try to abort properly established idle connections on the server side.

Best solution is posted at phpjs.org implementation of PHP function htmlentities

The format is htmlentities(string, quote_style, charset, double_encode) Full documentation on the PHP function which is identical can be read here

You Can Used This :

function ViewImage(){
 function getBase64(file) {
  return new Promise((resolve, reject) => {
    const reader = new FileReader();
    reader.readAsDataURL(file);
    reader.onload = () => resolve(reader.result);
    reader.onerror = error => reject(error);
  });
}
var file = document.querySelector('input[type="file"]').files[0];
getBase64(file).then(data =>$("#ImageBase46").val(data));
}

Add To Your Input onchange=ViewImage();

$url="http://example.com";

$html = file_get_contents($url);

$doc = new DOMDocument();
@$doc->loadHTML($html);

$tags = $doc->getElementsByTagName('img');

foreach ($tags as $tag) {
       echo $tag->getAttribute('src');
}

Coupled with reflection, I found Activator.CreateInstance to be very helpful in mapping stored procedure result to a custom class as described in the following answer.

I have just published to npm a micro-library called sort-helper (source on github). The idea is to import the helper by to create the comparison function for sort array method through the syntax items.sort(by(column, ...otherColumns)), with several way to express the columns to sort by:

• By key: persons.sort(by('lastName', 'firstName')),
• By selector: dates.sort(by(x => x.toISOString())),
• In descending order: [3, 2, 4, 1].sort(by(desc(n => n))) ? [3, 2, 1, 0],
• Ignoring case: ['B', 'D', 'c', 'a'].sort(by(ignoreCase(x => x))).join('') ? 'aBcD'.

It's similar to the nice thenBy mentioned in this answer but with the following differences that may be more to the taste of some:

• An approach more functional than object-oriented (see thenBy fluent API),
• A syntax a bit terser and still as much readable, natural almost like SQL.
• Fully implemented in TypeScript, to benefit from type safety and type expressivity.

Here is the simplest way given

 <script type="text/javascript">

        $(document).ready(function () {
            $("#chk_selall").change("click", function () {

                if (this.checked)
                {
                    //do something
                }
                if (!this.checked)
                {
                    //do something

                }

            });

        });

    </script>

The primary key class must define equals and hashCode methods

1. When implementing equals you should use instanceof to allow comparing with subclasses. If Hibernate lazy loads a one to one or many to one relation, you will have a proxy for the class instead of the plain class. A proxy is a subclass. Comparing the class names would fail.
   More technically: You should follow the Liskows Substitution Principle and ignore symmetricity.
2. The next pitfall is using something like name.equals(that.name) instead of name.equals(that.getName()). The first will fail, if that is a proxy.

Maybe

if (inventory.contains("bread") && !inventory.contains("water"))

Or

if (inventory.contains("bread")) {
    if (!inventory.contains("water")) {
        // do something here
    } 
}

You Can not Use the Intent's Context for Creating Intent. So You need to use your Fragment's Parent Activity Context

Intent intent = new Intent(getActivity(),MyClass.class);

All the gory details can be found in the current RFC on the topic: RFC 3986 (Uniform Resource Identifier (URI): Generic Syntax)

Based on this related answer, you are looking at a list that looks like: A-Z, a-z, 0-9, -, ., _, ~, :, /, ?, #, [, ], @, !, $, &, ', (, ), *, +, ,, ;, %, and =. Everything else must be url-encoded. Also, some of these characters can only exist in very specific spots in a URI and outside of those spots must be url-encoded (e.g. % can only be used in conjunction with url encoding as in %20), the RFC has all of these specifics.

A more consistent and robust way is to use NextResponderTextField You can configure it totally from interface builder with no need for setting the delegate or using view.tag.

All you need to do is

1. Set the class type of your UITextField to be NextResponderTextField
2. Then set the outlet of the nextResponderField to point to the next responder it can be anything UITextField or any UIResponder subclass. It can be also a UIButton and the library is smart enough to trigger the TouchUpInside event of the button only if it's enabled.

Here is the library in action:

It seems that your problem is simply a concurrency issue. The post function takes a callback argument to tell you when the post has been finished. You cannot make the alert in global scope like this and expect that the post has already been finished. You have to move it to the callback function.

Read the following: http://docs.python.org/library/codecs.html#module-encodings.utf_8_sig

Do this

with codecs.open("test_output", "w", "utf-8-sig") as temp:
    temp.write("hi mom\n")
    temp.write(u"This has ?")

The resulting file is UTF-8 with the expected BOM.

This works for non-associative arrays:

while(($item = array_shift($array2)) !== null && array_push($array1, $item));

My mac was connected to a 2.5GHZ network, I had to enable my wifi to 5GHz. And the problem disappeared.

Rebind your DatagridView to the source.

DataGridView dg1 = new DataGridView();
dg1.DataSource = src1;

// Update Data in src1

dg1.DataSource = null;
dg1.DataSource = src1;

you have to pass values with the single quotes

$(document).ready(function() {    
    $("#raaagh").click(function(){    
        $.ajax({
            url: 'ajax.php', //This is the current doc
            type: "POST",
            data: ({name: '145'}), //variables should be pass like this
            success: function(data){
                console.log(data);
                           }
        });  
        $.ajax({
    url:'ajax.php',
    data:"",
    dataType:'json',
    success:function(data1){
            var y1=data1;
            console.log(data1);
            }
        });

    });
});

try it it may work.......

The simplest way to show unallocated free space in a single command:

$ sudo sfdisk --list-free /dev/sdX

(Add the --quiet option if you don't need the extra info about sector size, etc.)

For using Google SignIn in Android app, you need

google-services.json

which you can generate using the instruction mentioned here

In Java 8 you can do it like this:

import java.util.*;
import java.util.stream.*;

List<JsonNode> datasets = StreamSupport
    .stream(datasets.get("datasets").spliterator(), false)
    .collect(Collectors.toList())

Hey check this, works for me... hope it work for u too

If list item contains ImageButton

Problem: OnItemClickListener just doesn’t repond any at all!

Reason: No idea

Solution: in code, set ImageButton's focus to “false”

1: ImageButton button = (ImageButton) convertView.findViewById(R.id.imageButton);

2: button.setFocusable(false);

    function loadMarkers(){
          {% for location in object_list %}
              var point = new google.maps.LatLng({{location.latitude}},{{location.longitude}});
              var marker = new google.maps.Marker({
              position: point,
              map: map,
              url: {{location.id}},
          });

          google.maps.event.addDomListener(marker, 'click', function() {
              window.location.href = this.url; });

          {% endfor %}

Example:

Process process = Process.Start(@"Data\myApp.exe");
int id = process.Id;
Process tempProc = Process.GetProcessById(id);
this.Visible = false;
tempProc.WaitForExit();
this.Visible = true;

With Hibernate 5.2, you can now force the UTC time zone using the following configuration property:

<property name="hibernate.jdbc.time_zone" value="UTC"/>

In this case a relatively simple GROUP BY can work, but in general, when there are additional columns where you can't order by but you want them from the particular row which they are associated with, you can either join back to the detail using all the parts of the key or use OVER():

Runnable example (Wofkflow20 error in original data corrected)

;WITH partitioned AS (
    SELECT company
        ,workflow
        ,date
        ,other_columns
        ,ROW_NUMBER() OVER(PARTITION BY company, workflow
                            ORDER BY date) AS seq
    FROM workflowTable
)
SELECT *
FROM partitioned WHERE seq = 1

You can use find with a Predicate as follows:

list.Find(x => x.Id == IdToFind);

This will return the first object in the list which meets the conditions defined by the predicate (ie in my example I am looking for an object with an ID).

Try this explanation on...

TypeSafe means that variables are statically checked for appropriate assignment at compile time. For example, consder a string or an integer. These two different data types cannot be cross-assigned (ie, you can't assign an integer to a string nor can you assign a string to an integer).

For non-typesafe behavior, consider this:

object x = 89;
int y;

if you attempt to do this:

y = x;

the compiler throws an error that says it can't convert a System.Object to an Integer. You need to do that explicitly. One way would be:

y = Convert.ToInt32( x );

The assignment above is not typesafe. A typesafe assignement is where the types can directly be assigned to each other.

Non typesafe collections abound in ASP.NET (eg, the application, session, and viewstate collections). The good news about these collections is that (minimizing multiple server state management considerations) you can put pretty much any data type in any of the three collections. The bad news: because these collections aren't typesafe, you'll need to cast the values appropriately when you fetch them back out.

For example:

Session[ "x" ] = 34;

works fine. But to assign the integer value back, you'll need to:

int i = Convert.ToInt32( Session[ "x" ] );

Read about generics for ways that facility helps you easily implement typesafe collections.

C# is a typesafe language but watch for articles about C# 4.0; interesting dynamic possibilities loom (is it a good thing that C# is essentially getting Option Strict: Off... we'll see).

public enum Tax {

NONE(1), SALES(2), IMPORT(3);

private final int value;
    private Tax(int value) {
        this.value = value;
    }

    public String toString() {
        return Integer.toString(value);
    }
}

class Test {
    System.out.println(Tax.NONE);    //Just an example.
}

First

ps -ef

to list all processes. Note the the process number of the one you want to kill. Then

kill 1234

were you replace 1234 with the process number that you want.

Alternatively, if you are absolutely certain that there is only one process with a particular name, or you want to kill multiple processes which share the same name

killall processname

If you are OK with converting the input button to a server side control by specifying runat="server", and you are using asp.net, an option could be using the HtmlButton.OnServerClick property.

<input id="foo "runat="server" type="button" onserverclick="foo_OnClick" />

This should work and call foo_OnClick in your server side code. Also notice that based on Microsoft documentation linked above, you should also be able to use the HTML 4.0 tag.

encode it with JSON

There are a few ways to get all unique combinations of a set of factors.

with(df, interaction(yad, per, drop=TRUE))   # gives labels
with(df, yad:per)                            # ditto

aggregate(numeric(nrow(df)), df[c("yad", "per")], length)    # gives a data frame

You can't: It's a security feature in all modern browsers.

For IE8, it's off by default, but can be reactivated using a security setting:

When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.

The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.

In all other current mainstream browsers I know of, it is also turned off. The file name is the best you can get.

More detailed info and good links in this question. It refers to getting the value server-side, but the issue is the same in JavaScript before the form's submission.

As pointed out in this answer, Django 1.9 added the Field.disabled attribute:

The disabled boolean argument, when set to True, disables a form field using the disabled HTML attribute so that it won’t be editable by users. Even if a user tampers with the field’s value submitted to the server, it will be ignored in favor of the value from the form’s initial data.

With Django 1.8 and earlier, to disable entry on the widget and prevent malicious POST hacks you must scrub the input in addition to setting the readonly attribute on the form field:

class ItemForm(ModelForm):
    def __init__(self, *args, **kwargs):
        super(ItemForm, self).__init__(*args, **kwargs)
        instance = getattr(self, 'instance', None)
        if instance and instance.pk:
            self.fields['sku'].widget.attrs['readonly'] = True

    def clean_sku(self):
        instance = getattr(self, 'instance', None)
        if instance and instance.pk:
            return instance.sku
        else:
            return self.cleaned_data['sku']

Or, replace if instance and instance.pk with another condition indicating you're editing. You could also set the attribute disabled on the input field, instead of readonly.

The clean_sku function will ensure that the readonly value won't be overridden by a POST.

Otherwise, there is no built-in Django form field which will render a value while rejecting bound input data. If this is what you desire, you should instead create a separate ModelForm that excludes the uneditable field(s), and just print them inside your template.

Swift 3 *

Code to convert 12 hours (i.e. AM and PM) to 24 hours format which includes-

Hours:Minutes:Seconds:AM/PM to Hours:Minutes:Seconds

func timeConversion24(time12: String) -> String {
    let dateAsString = time12
    let df = DateFormatter()
    df.dateFormat = "hh:mm:ssa"

    let date = df.date(from: dateAsString)
    df.dateFormat = "HH:mm:ss"

    let time24 = df.string(from: date!)
    print(time24)
    return time24
}

Input

07:05:45PM

Output

19:05:45

Similarly

Code to convert 24 hours to 12 hours (i.e. AM and PM) format which includes-

Hours:Minutes:Seconds to Hours:Minutes:Seconds:AM/PM

func timeConversion12(time24: String) -> String {
    let dateAsString = time24
    let df = DateFormatter()
    df.dateFormat = "HH:mm:ss"

    let date = df.date(from: dateAsString)
    df.dateFormat = "hh:mm:ssa"

    let time12 = df.string(from: date!)
    print(time12)
    return time12
}

Input

19:05:45

Output

07:05:45PM

In Debian you can also use: encguess:

$ encguess test.txt
test.txt  US-ASCII

Using ripgrep's replace option, it is possible to change the output to a capture group:

rg --only-matching --replace '$1' '(\d+) rofl'

• --only-matching or -o outputs only the part that matches instead of the whole line.
• --replace '$1' or -r replaces the output by the first capture group.

On XAMPP use

D:\xampp\apache\bin>httpd -t -D DUMP_VHOSTS

This will yield errors in your configuration of the virtual hosts

just copy " _CRT_SECURE_NO_WARNINGS " paste it on projects->properties->c/c++->preprocessor->preprocessor definitions click ok.it will work

Instead of

Image.open(picture.jpg)
Img.show

You should have

from PIL import Image

#...

img = Image.open('picture.jpg')
img.show()

You should probably also think about an other system to show your messages, because this way it will be a lot of manual work. Look into string substitution (using %s or .format()).

jQuery has some issues loading binary data using AJAX requests, as it does not yet implement some HTML5 XHR v2 capabilities, see this enhancement request and this discussion

Given that, you have one of two solutions:

First solution, abandon JQuery and use XMLHTTPRequest

Go with the native HTMLHTTPRequest, here is the code to do what you need

  var req = new XMLHttpRequest();
  req.open("GET", "/file.pdf", true);
  req.responseType = "blob";

  req.onload = function (event) {
    var blob = req.response;
    console.log(blob.size);
    var link=document.createElement('a');
    link.href=window.URL.createObjectURL(blob);
    link.download="Dossier_" + new Date() + ".pdf";
    link.click();
  };

  req.send();

Second solution, use the jquery-ajax-native plugin

The plugin can be found here and can be used to the XHR V2 capabilities missing in JQuery, here is a sample code how to use it

$.ajax({
  dataType: 'native',
  url: "/file.pdf",
  xhrFields: {
    responseType: 'blob'
  },
  success: function(blob){
    console.log(blob.size);
      var link=document.createElement('a');
      link.href=window.URL.createObjectURL(blob);
      link.download="Dossier_" + new Date() + ".pdf";
      link.click();
  }
});

See Introduction to the POM

finalName is created as:

<build>
    <finalName>${project.artifactId}-${project.version}</finalName>
</build>

One of the solutions is to add own property:

<properties>
    <finalName>${project.artifactId}-${project.version}</finalName>
</properties>
<build>
    <finalName>${finalName}</finalName>
 </build>

And now try:

mvn -DfinalName=build clean package

I have been successfull at impersonating users in another domain, but only with a trust set up between the 2 domains.

var token = IntPtr.Zero;
var result = LogonUser(userID, domain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref token);
if (result)
{
    return WindowsIdentity.Impersonate(token);
}

Well, first, you need to actually define a function before you can run it (and it doesn't need to be called main). For instance:

class Example(object):
    def run(self):
        print "Hello, world!"

if __name__ == '__main__':
    Example().run()

You don't need to use a class, though - if all you want to do is run some code, just put it inside a function and call the function, or just put it in the if block:

def main():
    print "Hello, world!"

if __name__ == '__main__':
    main()

or

if __name__ == '__main__':
    print "Hello, world!"

When you don't have a PC on hand, you could use Eruda, which is devtools for mobile browsers https://github.com/liriliri/eruda
It is provided as embeddable javascript and also a bookmarklet (pasting bookmarklet in chrome removes the javascript: prefix, so you have to type it yourself)

    protected void FindCsv()
    {
        string strToFind = "2";

        importFolder = @"C:\Documents and Settings\gmendez\Desktop\";

        fileName = "CSVFile.csv";

        connectionString= @"Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq="+importFolder+";Extended Properties=Text;HDR=No;FMT=Delimited";
        conn = new OdbcConnection(connectionString);

        System.Data.Odbc.OdbcDataAdapter  da = new OdbcDataAdapter("select * from [" + fileName + "]", conn);
        DataTable dt = new DataTable();
        da.Fill(dt);

        dt.Columns[0].ColumnName = "id";

        DataRow[] dr = dt.Select("id=" + strToFind);

        Response.Write(dr[0][0].ToString() + dr[0][1].ToString() + dr[0][2].ToString() + dr[0][3].ToString() + dr[0][4].ToString() + dr[0][5].ToString());
    }

a combination of answers gave me a very fast running time. using the shift method to create new column of next row values, then using the row_iterator function as @alisdt did, but here i changed it from iterrows to itertuples which is 100 times faster.

my script is for iterating dataframe of duplications in different length and add one second for each duplication so they all be unique.

# create new column with shifted values from the departure time column
df['next_column_value'] = df['column_value'].shift(1)
# create row iterator that can 'save' the next row without running for loop
row_iterator = df.itertuples()
# jump to the next row using the row iterator
last = next(row_iterator)
# because pandas does not support items alteration i need to save it as an object
t = last[your_column_num]
# run and update the time duplications with one more second each
for row in row_iterator:
    if row.column_value == row.next_column_value:
         t = t + add_sec
         df_result.at[row.Index, 'column_name'] = t
    else:
         # here i resetting the 'last' and 't' values
         last = row
         t = last[your_column_num]

Hope it will help.

onchange is only triggered when the control is blurred. Try onkeypress instead.

I have used the following before:

var my_form = $('#form-id');
var data = {};

$('input:not([type=checkbox]), input[type=checkbox]:selected, select, textarea', my_form).each(
    function() {
        var name = $(this).attr('name');
        var val = $(this).val();

        if (!data.hasOwnProperty(name)) {
            data[name] = new Array;
        }

        data[name].push(val);
    }
);

This is just written from memory, so might contain mistakes, but this should make an object called data that contains the values for all your inputs.

Note that you have to deal with checkboxes in a special way, to avoid getting the values of unchecked checkboxes. The same is probably true of radio inputs.

Also note using arrays for storing the values, as for one input name, you might have values from several inputs (checkboxes in particular).

I've had similar requirements as described in the question and it took a while to figure things out based on existing answers, so I would like to share my final solution.

Requirements

The state of my view (component, technically) can be changed by the user (filter settings, sorting options, etc.) When state changes happen, i.e. the user changes the sorting direction, I want to:

• Reflect the state changes in the URL
• Handle state changes, i.e. make an API call to receive a new result set

additionally, I would like to:

• Specify if the URL changes are considered in the browser history (back/forward) based on circumstances
• use complex objects as state params to provide greater flexibility in handling of state changes (optional, but makes life easier for example when some state changes trigger backend/API calls while others are handled by the frontend internally)

Solution: Change state without reloading component

A state change does not cause a component reload when using route parameters or query parameters. The component instance stays alive. I see no good reason to mess with the router state by using Location.go() or location.replaceState().

var state = { q: 'foo', sort: 'bar' }; 
var url = this.router.createUrlTree([], { relativeTo: this.activatedRoute, queryParams: state }).toString();
this.router.navigateByUrl(url);

The state object will be transformed to URL query params by Angular's Router:

https://localhost/some/route?q=foo&sort=bar

Solution: Handling state changes to make API calls

The state changes triggered above can be handled by subscribing to ActivatedRoute.queryParams:

export class MyComponent implements OnInit {

   constructor(private activatedRoute: ActivatedRoute) { }

   ngOnInit()
   {
      this.activatedRoute.queryParams.subscribe((params) => {
         // params is the state object passed to the router on navigation 
         // Make API calls here
      });
   }

}

The state object of the above axample will be passed as the params argument of the queryParams observable. In the handler API calls can be made if necessary.

But: I would prefer handling the state changes directly in my component and avoid the detour over ActivatedRoute.queryParams. IMO, navigating the router, letting Angular do routing magic and handle the queryParams change to do something, completely obfuscates whats happening in my component with regards to maintenability and readability of my code. What I do instead:

Compare the state passed in to queryParams observable with the current state in my component, do nothing, if it hasn't changed there and handle state changes directly instead:

export class MyComponent implements OnInit {

   private _currentState;

   constructor(private activatedRoute: ActivatedRoute) { }

   ngOnInit()
   {
      this.activatedRoute.queryParams.subscribe((params) => {
         // Following comparison assumes, that property order doesn't change
         if (JSON.stringify(this._currentState) == JSON.stringify(params)) return;
         // The followig code will be executed only when the state changes externally, i.e. through navigating to a URL with params by the user
         this._currentState = params;
         this.makeApiCalls();
      });
   }

   updateView()
   {          
      this.makeApiCalls();
      this.updateUri();
   }    

   updateUri()
   {
      var url = this.router.createUrlTree([], { relativeTo: this.activatedRoute, queryParams: this._currentState }).toString();
this.router.navigateByUrl(url);
   }
}

Solution: Specify browser history behavior

var createHistoryEntry = true // or false
var url = ... // see above
this.router.navigateByUrl(url, { replaceUrl : !createHistoryEntry});

Solution: Complex objects as state

This is beyond the original question but adresses common scenarios and might thus be useful: The state object above is limited to flat objects (an object with only simple string/bool/int/... properties but no nested objects). I found this limiting, because I need to distinguish between properties that need to be handled with a backend call and others, that are only used by the component internally. I wanted a state object like:

var state = { filter: { something: '', foo: 'bar' }, viewSettings: { ... } };

To use this state as queryParams object for the router, it needs to be flattened. I simply JSON.stringify all first level properties of the object:

private convertToParamsData(data) {
    var params = {};

    for (var prop in data) {
      if (Object.prototype.hasOwnProperty.call(data, prop)) {
        var value = data[prop];
        if (value == null || value == undefined) continue;
        params[prop] = JSON.stringify(value, (k, v) => {
          if (v !== null) return v
        });
      }
    }
    return params;
 }

and back, when handling the queryParams returned passed in by the router:

private convertFromParamsData(params) {
    var data = {};

    for (var prop in params) {
      if (Object.prototype.hasOwnProperty.call(params, prop)) {
        data[prop] = JSON.parse(params[prop]);
      }
    }
    return data;
}

Finally: A ready-to-use Angular service

And finally, all of this isolated in one simple service:

import { Injectable } from '@angular/core';
import { ActivatedRoute, Router } from '@angular/router';
import { Observable } from 'rxjs';
import { Location } from '@angular/common';
import { map, filter, tap } from 'rxjs/operators';

@Injectable()
export class QueryParamsService {

  private currentParams: any;

  externalStateChange: Observable<any>;

  constructor(private activatedRoute: ActivatedRoute, private router: Router, private location: Location) {

    this.externalStateChange = this.activatedRoute.queryParams
      .pipe(map((flatParams) => {
        var params = this.convertFromParamsData(flatParams);
        return params
      }))
      .pipe(filter((params) => {
        return !this.equalsCurrentParams(params);
      }))
      .pipe(tap((params) => {
        this.currentParams = params;
      }));
  }

  setState(data: any, createHistoryEntry = false) {
    var flat = this.convertToParamsData(data);
    const url = this.router.createUrlTree([], { relativeTo: this.activatedRoute, queryParams: flat }).toString();
    this.currentParams = data;
    this.router.navigateByUrl(url, { replaceUrl: !createHistoryEntry });
  }

  private equalsCurrentParams(data) {
    var isEqual = JSON.stringify(data) == JSON.stringify(this.currentParams);
    return isEqual;
  }

  private convertToParamsData(data) {
    var params = {};

    for (var prop in data) {
      if (Object.prototype.hasOwnProperty.call(data, prop)) {
        var value = data[prop];
        if (value == null || value == undefined) continue;
        params[prop] = JSON.stringify(value, (k, v) => {
          if (v !== null) return v
        });
      }
    }
    return params;
  }

  private convertFromParamsData(params) {
    var data = {};

    for (var prop in params) {
      if (Object.prototype.hasOwnProperty.call(params, prop)) {
        data[prop] = JSON.parse(params[prop]);
      }
    }
    return data;
  }
}

which can be used like:

@Component({
  selector: "app-search",
  templateUrl: "./search.component.html",
  styleUrls: ["./search.component.scss"],
  providers: [QueryParamsService]
})
export class ProjectSearchComponent implements OnInit {

    filter : any;

    viewSettings : any;

    constructor(private queryParamsService: QueryParamsService) { }

    ngOnInit(): void {

        this.queryParamsService.externalStateChange
          .pipe(debounce(() => interval(500))) // Debounce optional
          .subscribe(params => {
           // Set state from params, i.e.
           if (params.filter) this.filter = params.filter;
           if (params.viewSettings) this.viewSettings = params.viewSettings;

           // You might want to init this.filter, ... with default values here
           // If you want to write default values to URL, you can call setState here
            this.queryParamsService.setState(params, false); // false = no history entry

            this.initializeView(); //i.e. make API calls        
         });
     }

     updateView() {

       var data = {
         filter: this.filter,
         viewSettings: this.viewSettings
       };

       this.queryParamsService.setState(data, true);

       // Do whatever to update your view
     }

  // ...

}

Don't forget the providers: [QueryParamsService] statement on component level to create a new service instance for the component. Don't register the service globally on app module.

Instead of playing with tags, I took different approach. Made delegate for my subclass of UITableViewCell(OptionButtonsCell) and added an indexPath var. From my button in storyboard I connected @IBAction to the OptionButtonsCell and there I send delegate method with the right indexPath to anyone interested. In cell for index path I set current indexPath and it works :)

Let the code speak for itself:

Swift 3 Xcode 8

OptionButtonsTableViewCell.swift

import UIKit
protocol OptionButtonsDelegate{
    func closeFriendsTapped(at index:IndexPath)
}
class OptionButtonsTableViewCell: UITableViewCell {
    var delegate:OptionButtonsDelegate!
    @IBOutlet weak var closeFriendsBtn: UIButton!
    var indexPath:IndexPath!
    @IBAction func closeFriendsAction(_ sender: UIButton) {
        self.delegate?.closeFriendsTapped(at: indexPath)
    }
}

MyTableViewController.swift

class MyTableViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, OptionButtonsDelegate {...

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "optionCell") as! OptionButtonsTableViewCell
    cell.delegate = self
    cell.indexPath = indexPath
    return cell   
}

func closeFriendsTapped(at index: IndexPath) {
     print("button tapped at index:\(index)")
}

If you want to use form's reset feature, you'd better to use this:

$('input[type=checkbox]').prop('checked',true); 

OR

$('input[type=checkbox]').prop('checked',false);

Looks like removeAttr() can not be reset by form.reset().

I know this is old but I just encountered the issue in my team (some mac, some linux, some windows , all vscode).

solution was to set the line ending in vscode's settings:

.vscode/settings.json

{
    "files.eol": "\n",
}

https://qvault.io/2020/06/18/how-to-get-consistent-line-breaks-in-vs-code-lf-vs-crlf/

Add this line under the dependencies in your gradle file

compile 'com.android.support:support-annotations:27.1.1'

If you are using PHP's password_hash() with the PASSWORD_DEFAULT algorithm to generate the bcrypt hash (which I would assume is a large percentage of people reading this question) be sure to keep in mind that in the future password_hash() might use a different algorithm as the default and this could therefore affect the length of the hash (but it may not necessarily be longer).

From the manual page:

Note that this constant is designed to change over time as new and stronger algorithms are added to PHP. For that reason, the length of the result from using this identifier can change over time. Therefore, it is recommended to store the result in a database column that can expand beyond 60 characters (255 characters would be a good choice).

Using bcrypt, even if you have 1 billion users (i.e. you're currently competing with facebook) to store 255 byte password hashes it would only ~255 GB of data - about the size of a smallish SSD hard drive. It is extremely unlikely that storing the password hash is going to be the bottleneck in your application. However in the off chance that storage space really is an issue for some reason, you can use PASSWORD_BCRYPT to force password_hash() to use bcrypt, even if that's not the default. Just be sure to stay informed about any vulnerabilities found in bcrypt and review the release notes every time a new PHP version is released. If the default algorithm is ever changed it would be good to review why and make an informed decision whether to use the new algorithm or not.

Verified build settings such as Platform Target are all the same (x86).

That's not what the crash log says:

Assembly manager loaded from: C:\Windows\Microsoft.NET\Framework64

Note the 64 in the name, that's the home of the 64-bit version of the framework. Set the Target platform setting on your EXE project, not your class library project. The XxxDevicesService EXE project determines the bitness of the process.

The ls command has a parameter -t to sort by time. You can then grab the first (newest) with head -1.

ls -t b2* | head -1

But beware: Why you shouldn't parse the output of ls

My personal opinion: parsing ls is only dangerous when the filenames can contain funny characters like spaces or newlines. If you can guarantee that the filenames will not contain funny characters then parsing ls is quite safe.

If you are developing a script which is meant to be run by many people on many systems in many different situations then I very much do recommend to not parse ls.

Here is how to do it "right": How can I find the latest (newest, earliest, oldest) file in a directory?

unset -v latest
for file in "$dir"/*; do
  [[ $file -nt $latest ]] && latest=$file
done

You can write that in single line, but it's not something that someone would be able to read. Keep it like you already wrote it, it's already beautiful by itself.

If you have too much if/else constructs, you may think about using of different datastructures, like Dictionaries (to look up keys) or Collection (to run conditional LINQ queries on it)

The "iterable interface" in python consists of two methods __next__() and __iter__(). The __next__ function is the most important, as it defines the iterator behavior - that is, the function determines what value should be returned next. The __iter__() method is used to reset the starting point of the iteration. Often, you will find that __iter__() can just return self when __init__() is used to set the starting point.

See the following code for defining a Class Reverse which implements the "iterable interface" and defines an iterator over any instance from any sequence class. The __next__() method starts at the end of the sequence and returns values in reverse order of the sequence. Note that instances from a class implementing the "sequence interface" must define a __len__() and a __getitem__() method.

class Reverse:
    """Iterator for looping over a sequence backwards."""
    def __init__(self, seq):
        self.data = seq
        self.index = len(seq)

    def __iter__(self):
        return self

    def __next__(self):
        if self.index == 0:
            raise StopIteration
        self.index = self.index - 1
        return self.data[self.index]

>>> rev = Reverse('spam')
>>> next(rev)   # note no need to call iter()
'm'
>>> nums = Reverse(range(1,10))
>>> next(nums)

svn merge will merge revisions, not revert them. i.e. if you have some addition in your HEAD version then merge that with a previous revision, then the change will persist.

I use svn cat then redirect it into the file:

svn cat -r 851 l3toks.dtx > l3toks.dtx

Then you have the 851 content in that file and can check it back in.

You may already have this working, but the I created a test project with the classes below allowing you to retrieve the data into an entity, projection or dto.

Projection - this will return the code column twice, once named code and also named text (for example only). As you say above, you don't need the @Projection annotation

import org.springframework.beans.factory.annotation.Value;

public interface DeadlineTypeProjection {
    String getId();

    // can get code and or change name of getter below
    String getCode();

    // Points to the code attribute of entity class
    @Value(value = "#{target.code}")
    String getText();
}

DTO class - not sure why this was inheriting from your base class and then redefining the attributes. JsonProperty just an example of how you'd change the name of the field passed back to a REST end point

import com.fasterxml.jackson.annotation.JsonProperty;
import lombok.AllArgsConstructor;
import lombok.Data;

@Data
@AllArgsConstructor
public class DeadlineType {
    String id;

    // Use this annotation if you need to change the name of the property that is passed back from controller
    // Needs to be called code to be used in Repository
    @JsonProperty(value = "text")
    String code;

}

Entity class

import lombok.Data;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

@Data
@Entity
@Table(name = "deadline_type")
public class ABDeadlineType {

    @Id
    private String id;
    private String code;
}

Repository - your repository extends JpaRepository<ABDeadlineType, Long> but the Id is a String, so updated below to JpaRepository<ABDeadlineType, String>

import com.example.demo.entity.ABDeadlineType;
import com.example.demo.projection.DeadlineTypeProjection;
import com.example.demo.transfer.DeadlineType;
import org.springframework.data.jpa.repository.JpaRepository;

import java.util.List;

public interface ABDeadlineTypeRepository extends JpaRepository<ABDeadlineType, String> {

    List<ABDeadlineType> findAll();

    List<DeadlineType> findAllDtoBy();

    List<DeadlineTypeProjection> findAllProjectionBy();

}

Example Controller - accesses the repository directly to simplify code

@RequestMapping(value = "deadlinetype")
@RestController
public class DeadlineTypeController {

    private final ABDeadlineTypeRepository abDeadlineTypeRepository;

    @Autowired
    public DeadlineTypeController(ABDeadlineTypeRepository abDeadlineTypeRepository) {
        this.abDeadlineTypeRepository = abDeadlineTypeRepository;
    }

    @GetMapping(value = "/list")
    public ResponseEntity<List<ABDeadlineType>> list() {

        List<ABDeadlineType> types = abDeadlineTypeRepository.findAll();
        return ResponseEntity.ok(types);
    }

    @GetMapping(value = "/listdto")
    public ResponseEntity<List<DeadlineType>> listDto() {

        List<DeadlineType> types = abDeadlineTypeRepository.findAllDtoBy();
        return ResponseEntity.ok(types);
    }

    @GetMapping(value = "/listprojection")
    public ResponseEntity<List<DeadlineTypeProjection>> listProjection() {

        List<DeadlineTypeProjection> types = abDeadlineTypeRepository.findAllProjectionBy();
        return ResponseEntity.ok(types);
    }
}

Hope that helps

Definitely avoid using eval to do something like this, or you will open yourself to XSS (Cross-Site Scripting) vulnerabilities.

For example, if you were to use the eval solutions proposed here, a nefarious user could send a link to their victim that looked like this:

http://yoursite.com/foo.html?func=function(){alert('Im%20In%20Teh%20Codez');}

And their javascript, not yours, would get executed. This code could do something far worse than just pop up an alert of course; it could steal cookies, send requests to your application, etc.

So, make sure you never eval untrusted code that comes in from user input (and anything on the query string id considered user input). You could take user input as a key that will point to your function, but make sure that you don't execute anything if the string given doesn't match a key in your object. For example:

// set up the possible functions:
var myFuncs = {
  func1: function () { alert('Function 1'); },
  func2: function () { alert('Function 2'); },
  func3: function () { alert('Function 3'); },
  func4: function () { alert('Function 4'); },
  func5: function () { alert('Function 5'); }
};
// execute the one specified in the 'funcToRun' variable:
myFuncs[funcToRun]();

This will fail if the funcToRun variable doesn't point to anything in the myFuncs object, but it won't execute any code.

Try being explicit about all the border properties. For example:

border:1px solid black;

See Border shorthand property. Although the other bits are optional some browsers don't set the width or colour to a default you'd expect. In your case I'd bet that it's the width that's zero unless specified.

You need to add annotations to the Junit class, telling it to use the SpringJunitRunner. The ones you want are:

@ContextConfiguration("/test-context.xml")
@RunWith(SpringJUnit4ClassRunner.class)

This tells Junit to use the test-context.xml file in same directory as your test. This file should be similar to the real context.xml you're using for spring, but pointing to test resources, naturally.

For the kotlin users out there here is a kotlin extension method that has worked for my use cases:

fun View.hideKeyboard() {
    val imm = this.context.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(windowToken, 0)
}

put it in a file called ViewExtensions (or what have you) and call it on your views just like a normal method.

Update: The JSESSIONID stuff here is only for older containers. Please use jt's currently accepted answer unless you are using < Tomcat 6.0.19 or < Tomcat 5.5.28 or another container that does not support HttpOnly JSESSIONID cookies as a config option.

When setting cookies in your app, use

response.setHeader( "Set-Cookie", "name=value; HttpOnly");

However, in many webapps, the most important cookie is the session identifier, which is automatically set by the container as the JSESSIONID cookie.

If you only use this cookie, you can write a ServletFilter to re-set the cookies on the way out, forcing JSESSIONID to HttpOnly. The page at http://keepitlocked.net/archive/2007/11/05/java-and-httponly.aspx http://alexsmolen.com/blog/?p=16 suggests adding the following in a filter.

if (response.containsHeader( "SET-COOKIE" )) {
  String sessionid = request.getSession().getId();
  response.setHeader( "SET-COOKIE", "JSESSIONID=" + sessionid 
                      + ";Path=/<whatever>; Secure; HttpOnly" );
} 

but note that this will overwrite all cookies and only set what you state here in this filter.

If you use additional cookies to the JSESSIONID cookie, then you'll need to extend this code to set all the cookies in the filter. This is not a great solution in the case of multiple-cookies, but is a perhaps an acceptable quick-fix for the JSESSIONID-only setup.

Please note that as your code evolves over time, there's a nasty hidden bug waiting for you when you forget about this filter and try and set another cookie somewhere else in your code. Of course, it won't get set.

This really is a hack though. If you do use Tomcat and can compile it, then take a look at Shabaz's excellent suggestion to patch HttpOnly support into Tomcat.

Another option if you really want to repackage the other JARs contents inside your single resultant JAR is the Maven Assembly plugin. It unpacks and then repacks everything into a directory via <unpack>true</unpack>. Then you'd have a second pass that built it into one massive JAR.

Another option is the OneJar plugin. This performs the above repackaging actions all in one step.

Sharding is just another name for "horizontal partitioning" of a database. You might want to search for that term to get it clearer.

From Wikipedia:

Horizontal partitioning is a design principle whereby rows of a database table are held separately, rather than splitting by columns (as for normalization). Each partition forms part of a shard, which may in turn be located on a separate database server or physical location. The advantage is the number of rows in each table is reduced (this reduces index size, thus improves search performance). If the sharding is based on some real-world aspect of the data (e.g. European customers vs. American customers) then it may be possible to infer the appropriate shard membership easily and automatically, and query only the relevant shard.

Some more information about sharding:

Firstly, each database server is identical, having the same table structure. Secondly, the data records are logically split up in a sharded database. Unlike the partitioned database, each complete data record exists in only one shard (unless there's mirroring for backup/redundancy) with all CRUD operations performed just in that database. You may not like the terminology used, but this does represent a different way of organizing a logical database into smaller parts.

Update: You wont break MVC. The work of determining the correct shard where to store the data would be transparently done by your data access layer. There you would have to determine the correct shard based on the criteria which you used to shard your database. (As you have to manually shard the database into some different shards based on some concrete aspects of your application.) Then you have to take care when loading and storing the data from/into the database to use the correct shard.

Maybe this example with Java code makes it somewhat clearer (it's about the Hibernate Shards project), how this would work in a real world scenario.

To address the "why sharding": It's mainly only for very large scale applications, with lots of data. First, it helps minimizing response times for database queries. Second, you can use more cheaper, "lower-end" machines to host your data on, instead of one big server, which might not suffice anymore.

TRY:

SELECT EXTRACT(YEAR FROM (STR_TO_DATE(subdateshow, '%d/%m/%Y')));

Can also be done this way..

regex=re.compile('^hello')

## THIS WAY YOU CAN CHECK FOR MULTIPLE STRINGS
## LIKE
## regex=re.compile('^hello|^john|^world')

if re.match(regex, somestring):
    print("Yes")

Configure your webserver to send caching control HTTP headers for the script.

Fake headers in the HTML documents:

1. Aren't as well supported as real HTTP headers
2. Apply to the HTML document, not to resources that it links to

I know this is an old question, and most people have replied with good answers. But for reference and hopefully saving somebody else's time. Check if your function:

$(document).ready(function(){}

is being called after you have loaded the JQuery library

input width is 10 + 2 times 1 px for border

deferred.done()

adds handlers to be called only when Deferred is resolved. You can add multiple callbacks to be called.

var url = 'http://jsonplaceholder.typicode.com/posts/1';
$.ajax(url).done(doneCallback);

function doneCallback(result) {
    console.log('Result 1 ' + result);
}

You can also write above like this,

function ajaxCall() {
    var url = 'http://jsonplaceholder.typicode.com/posts/1';
    return $.ajax(url);
}

$.when(ajaxCall()).then(doneCallback, failCallback);

deferred.then()

adds handlers to be called when Deferred is resolved, rejected or still in progress.

var url = 'http://jsonplaceholder.typicode.com/posts/1';
$.ajax(url).then(doneCallback, failCallback);

function doneCallback(result) {
    console.log('Result ' + result);
}

function failCallback(result) {
    console.log('Result ' + result);
}

Frames were not deprecated in HTML5, but were deprecated in XHTML 1.1 Strict and 2.0, but remained in XHTML Transitional and returned in HTML5. Also here is an interesting article on using CSS to mimic frames without frames. I just tested it in IE 8, FF 3, Opera 11, Safari 5, Chrome 8. I love frames, but they do have their problems, particularly with search engines, bookmarks and printing and with CSS you can create print or display only content. I'm hoping to upgrade Alex's XHTML/CSS frame without frames solution to HTML5/CSS3.

Without knowing all the information... You could bind a reset trigger to your model or controller:

this.bind("reset", this.updateView);

and when you want to reset the views, trigger a reset.

For your callback, do something like:

updateView: function() {
  view.remove();
  view.render();
};

The problem is that your class contains a managed RAW pointer but does not implement the rule of three (five in C++11). As a result you are getting (expectedly) a double delete because of copying.

If you are learning you should learn how to implement the rule of three (five). But that is not the correct solution to this problem. You should be using standard container objects rather than try to manage your own internal container. The exact container will depend on what you are trying to do but std::vector is a good default (and you can change afterwords if it is not opimal).

#include <queue>
#include <vector>

class Test{
    std::vector<int> myArray;

    public:
    Test(): myArray(10){
    }    
};

int main(){
    queue<Test> q
    Test t;
    q.push(t);
}

The reason you should use a standard container is the separation of concerns. Your class should be concerned with either business logic or resource management (not both). Assuming Test is some class you are using to maintain some state about your program then it is business logic and it should not be doing resource management. If on the other hand Test is supposed to manage an array then you probably need to learn more about what is available inside the standard library.

Updated Solution - using the schema solution that we were debating. This gets you to your answer:

.scroll-menu{
   min-width: 220px;
   max-height: 90vh;
   overflow: auto;

I've just tried the following, and it appears to do the trick on Chrome 53 - it also disables the "Use password for:" drop down when entering the password field.

Simply set your password input type to text, and then add the onfocus handler (inline or via jQuery/vanilla JS) to set the type to password:

onfocus="this.setAttribute('type','password')"

Or even better:

onfocus="if(this.getAttribute('type')==='text') this.setAttribute('type','password')"

I received the exact same error message. Except that my error message said "Could not load file or assembly 'EntityFramework, Version=6.0.0.0...", because I installed EF 6.1.1. Here's what I did to resolve the problem.

1) I started NuGet Manager Console by clicking on Tools > NuGet Package Manager > Package Manager Console 2) I uninstalled the installed EntityFramework 6.1.1 by typing the following command:

Uninstall-package EntityFramework

3) Once I received confirmation that the package has been uninstalled successfully, I installed the 5.0.0 version by typing the following command:

Install-Package EntityFramework -version 5.0.0

The problem is resolved.

Because UTF-8 is multibyte and there is no char corresponding to your combination of \xe9 plus following space.

Why should it succeed in both utf-8 and latin-1?

Here how the same sentence should be in utf-8:

>>> o.decode('latin-1').encode("utf-8")
'a test of \xc3\xa9 char'

First cast your Edit text like this:

TextView tekst = (TextView) findViewById(R.id.editText1);
tekst.setText(text);

And after that close the DB not befor this line...

 myDataBaseHelper.close(); 

There you go! You are welcome!

    var tmp = {}, out = [];
    for(var i = 0, n = this.length; i < n; ++i)

    }

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

I had the same issue, so tried a few things. One of which seemed to work for me - removing the width and adding a float to the body tag.

May not work for all instances, but in the scenario I recently had, hiding overflow on content elements was a no go...

Try this code.

<!DOCTYPE HTML>
<html>
  <head>
    <title>PhoneGap</title>

        <script type="text/javascript" charset="utf-8" src="cordova-1.5.0.js"></script>      
        <script type="text/javascript" charset="utf-8">

            function onLoad()
            {
                  document.addEventListener("deviceready", onDeviceReady, true);
            }

            function exitFromApp()
             {
                navigator.app.exitApp();
             }

        </script>

    </head>

    <body onload="onLoad();">
       <button name="buttonClick" onclick="exitFromApp()">Click Me!</button>
    </body>
</html>

Replace src="cordova-1.5.0.js" with your phonegap js .

The easiest way would be at the application level. In the file

app/Providers/AppServiceProvider.php

add the following:

use Illuminate\Support\Facades\URL;

and in the boot() method add the following:

$this->app['request']->server->set('HTTPS', true);
URL::forceScheme('https');

This should redirect all request to https at the application level.

( Note: this has been tested with laravel 5.5 LTS )

From experience I'll just note that while it is the C++ way to put formerly-static functions into the anonymous namespace, older compilers can sometimes have problems with this. I currently work with a few compilers for our target platforms, and the more modern Linux compiler is fine with placing functions into the anonymous namespace.

But an older compiler running on Solaris, which we are wed to until an unspecified future release, will sometimes accept it, and other times flag it as an error. The error is not what worries me, it's what it might be doing when it accepts it. So until we go modern across the board, we are still using static (usually class-scoped) functions where we'd prefer the anonymous namespace.

While the instructions on the Boost web site are helpful, here is a condensed version that also builds x64 libraries.

• You only need to do this if you are using one of the libraries mentioned in section 3 of the instructions page. (E.g., to use Boost.Filesystem requires compilation.) If you are not using any of those, just unzip and go.

Build the 32-bit libraries

This installs the Boost header files under C:\Boost\include\boost-(version), and the 32-bit libraries under C:\Boost\lib\i386. Note that the default location for the libraries is C:\Boost\lib but you’ll want to put them under an i386 directory if you plan to build for multiple architectures.

1. Unzip Boost into a new directory.
2. Start a 32-bit MSVC command prompt and change to the directory where Boost was unzipped.
3. Run: bootstrap

4. Run: b2 toolset=msvc-12.0 --build-type=complete --libdir=C:\Boost\lib\i386 install

   • For Visual Studio 2012, use toolset=msvc-11.0
   • For Visual Studio 2010, use toolset=msvc-10.0
   • For Visual Studio 2017, use toolset=msvc-14.1

5. Add C:\Boost\include\boost-(version) to your include path.

6. Add C:\Boost\lib\i386 to your libs path.

Build the 64-bit libraries

This installs the Boost header files under C:\Boost\include\boost-(version), and the 64-bit libraries under C:\Boost\lib\x64. Note that the default location for the libraries is C:\Boost\lib but you’ll want to put them under an x64 directory if you plan to build for multiple architectures.

1. Unzip Boost into a new directory.
2. Start a 64-bit MSVC command prompt and change to the directory where Boost was unzipped.
3. Run: bootstrap
4. Run: b2 toolset=msvc-12.0 --build-type=complete --libdir=C:\Boost\lib\x64 architecture=x86 address-model=64 install
   • For Visual Studio 2012, use toolset=msvc-11.0
   • For Visual Studio 2010, use toolset=msvc-10.0
5. Add C:\Boost\include\boost-(version) to your include path.
6. Add C:\Boost\lib\x64 to your libs path.

Another very subtle cause:

Multi-flavor library should be compiled in specific way than a normal single-flavored. Otherwise it silently produces cannot resolve symbols error.

From android API Level 19, when I want to instance JSONArray object I put JSONObject directly as parameter like below:

JSONArray jsonArray=new JSONArray(jsonObject);

JSONArray has constructor to accept object.

The Instagram API requires user authentication through OAuth to access the recent media endpoint for a user. There doesn't appear to be any other way right now to get all media for a user.

Note that you should note that your logic flow must never rely on accessing the HashMap elements in some order, simply put because HashMaps are not ordered Collections and that is not what they are aimed to do. (You can read more about odered and sorter collections in this post).

Back to the post, you already did half the job by loading the first element key:

Object myKey = statusName.keySet().toArray()[0];

Just call map.get(key) to get the respective value:

Object myValue = statusName.get(myKey);

You can add:

-ErrorVariable errvar

And then look in $errvar.

Not exactly sure why, or what I missed, but after running trough most of the answers and failing. I realized that with this .env file:

MY_VAR="hello there!"
MY_OTHER_VAR=123

I could simply do this:

source .env
echo $MY_VAR

Outputs: Hello there!

Seems to work just fine in Ubuntu linux.

Try ["points.bean.pointsBase"]

Some of the columns in MySQL have an "on update" clause, see:

mysql> SHOW COLUMNS FROM your_table_name;

I'm not sure how to update this but will post an edit when I find out.

table {
    background: #fff;
    box-shadow: 0 0 0 10px #fff;
    margin: 10px;
    width: calc(100% - 20px); 
}

Update (9/25/2018)

Newer versions of AngularJS (>= 1.3.0) allow you to do this with only a variable (no function needed):

<li ng-repeat="x in [].constructor(number) track by $index">
    <span>{{ $index+1 }}</span>
</li>

$scope.number = 5;

This was not possible at the time the question was first asked. Credit to @Nikhil Nambiar from his answer below for this update

Original (5/29/2013)

At the moment, ng-repeat only accepts a collection as a parameter, but you could do this:

<li ng-repeat="i in getNumber(number)">
    <span>{{ $index+1 }}</span>
</li>

And somewhere in your controller:

$scope.number = 5;
$scope.getNumber = function(num) {
    return new Array(num);   
}

This would allow you to change $scope.number to any number as you please and still maintain the binding you're looking for.

EDIT (1/6/2014) -- Newer versions of AngularJS (>= 1.1.5) require track by $index:

<li ng-repeat="i in getNumber(number) track by $index">
    <span>{{ $index+1 }}</span>
</li>

Here is a fiddle with a couple of lists using the same getNumber function.

One possible C loop would be:

#include <stdio.h>
int main()
{
    int c;
    while ((c = getchar()) != EOF)
    {
        /*
        ** Do something with c, such as check against '\n'
        ** and increment a line counter.
        */
    }
}

For now, I would ignore feof and similar functions. Exprience shows that it is far too easy to call it at the wrong time and process something twice in the belief that eof hasn't yet been reached.

Pitfall to avoid: using char for the type of c. getchar returns the next character cast to an unsigned char and then to an int. This means that on most [sane] platforms the value of EOF and valid "char" values in c don't overlap so you won't ever accidentally detect EOF for a 'normal' char.

I found a difference when creating a Form Contact: slim (recommended by boostrap 4.5):

• After sending an email the global variables get stuck, and that makes if the user gives f5 (reload page) it is sent again. min:
• The previous error will be solved. how i suffered!

You can use the rpad and lpad functions to pad numbers to the right or to the left, respectively. Note that this does not work directly on numbers, so you'll have to use ::char or ::text to cast them:

SELECT RPAD(numcol::text, 3, '0'), -- Zero-pads to the right up to the length of 3
       LPAD(numcol::text, 3, '0'), -- Zero-pads to the left up to the length of 3
FROM   my_table

A simple way to solve the issue would be to wrap the try/catch in a while loop and maintain a count. This way you could prevent an infinite loop by checking a count against some other variable while maintaining a log of your failures. It isn't the most exquisite solution, but it would work.

I'd Use the following:

SHOW VARIABLES LIKE 'query_cache_type';
SET SESSION query_cache_type = OFF;
SHOW VARIABLES LIKE 'query_cache_type';

Sometimes we have to use loops, for example, when we don't know how many iterations we need to get the result. Take while loops as an example. Below are methods you absolutely should avoid:

a=numeric(0)
b=1
system.time(
  {
    while(b<=1e5){
      b=b+1
      a<-c(a,pi)
    }
  }
)
# user  system elapsed 
# 13.2     0.0    13.2 

a=numeric(0)
b=1
system.time(
  {
    while(b<=1e5){
      b=b+1
      a<-append(a,pi)
    }
  }
)
# user  system elapsed 
# 11.06    5.72   16.84 

These are very inefficient because R copies the vector every time it appends.

The most efficient way to append is to use index. Note that this time I let it iterate 1e7 times, but it's still much faster than c.

a=numeric(0)
system.time(
  {
    while(length(a)<1e7){
      a[length(a)+1]=pi
    }
  }
)
# user  system elapsed 
# 5.71    0.39    6.12  

This is acceptable. And we can make it a bit faster by replacing [ with [[.

a=numeric(0)
system.time(
  {
    while(length(a)<1e7){
      a[[length(a)+1]]=pi
    }
  }
)
# user  system elapsed 
# 5.29    0.38    5.69   

Maybe you already noticed that length can be time consuming. If we replace length with a counter:

a=numeric(0)
b=1
system.time(
  {
    while(b<=1e7){
      a[[b]]=pi
      b=b+1
    }
  }
)
# user  system elapsed 
# 3.35    0.41    3.76

As other users mentioned, pre-allocating the vector is very helpful. But this is a trade-off between speed and memory usage if you don't know how many loops you need to get the result.

a=rep(NaN,2*1e7)
b=1
system.time(
  {
    while(b<=1e7){
      a[[b]]=pi
      b=b+1
    }
    a=a[!is.na(a)]
  }
)
# user  system elapsed 
# 1.57    0.06    1.63 

An intermediate method is to gradually add blocks of results.

a=numeric(0)
b=0
step_count=0
step=1e6
system.time(
  {
    repeat{
      a_step=rep(NaN,step)
      for(i in seq_len(step)){
        b=b+1
        a_step[[i]]=pi
        if(b>=1e7){
          a_step=a_step[1:i]
          break
        }
      }
      a[(step_count*step+1):b]=a_step
      if(b>=1e7) break
      step_count=step_count+1
    }
  }
)
#user  system elapsed 
#1.71    0.17    1.89

I've found good example here Display-char-as-Hexadecimal-String-in-C++:

  std::vector<char> randomBytes(n);
  file.read(&randomBytes[0], n);

  // Displaying bytes: method 1
  // --------------------------
  for (auto& el : randomBytes)
    std::cout << std::setfill('0') << std::setw(2) << std::hex << (0xff & (unsigned int)el);
  std::cout << '\n';

  // Displaying bytes: method 2
  // --------------------------
  for (auto& el : randomBytes)
    printf("%02hhx", el);
  std::cout << '\n';
  return 0;

Method 1 as shown above is probably the more C++ way:

Cast to an unsigned int
Use std::hex to represent the value as hexadecimal digits
Use std::setw and std::setfill from <iomanip> to format
Note that you need to mask the cast int against 0xff to display the least significant byte:
(0xff & (unsigned int)el).

Otherwise, if the highest bit is set the cast will result in the three most significant bytes being set to ff.

unset is a function, not an operator. Use it like unset($_SESSION['key']); to unset that session key. You can, however, use session_destroy(); as well. (Make sure to start the session with session_start(); as well)

Use something like header( 'Location: /my-other-page.html' ); to redirect. You can't have sent any other data on the page before you do this though.

If you want to make temporary files in Python, there's a module called tempfile in Python's standard libraries. If you want to launch other programs to operate on the file, use tempfile.mkstemp() to create files, and os.fdopen() to access the file descriptors that mkstemp() gives you.

Incidentally, you say you're running commands from a Python program? You should almost certainly be using the subprocess module.

So you can quite merrily write code that looks like:

import subprocess
import tempfile
import os

(fd, filename) = tempfile.mkstemp()
try:
    tfile = os.fdopen(fd, "w")
    tfile.write("Hello, world!\n")
    tfile.close()
    subprocess.Popen(["/bin/cat", filename]).wait()        
finally:
    os.remove(filename)

Running that, you should find that the cat command worked perfectly well, but the temporary file was deleted in the finally block. Be aware that you have to delete the temporary file that mkstemp() returns yourself - the library has no way of knowing when you're done with it!

(Edit: I had presumed that NamedTemporaryFile did exactly what you're after, but that might not be so convenient - the file gets deleted immediately when the temp file object is closed, and having other processes open the file before you've closed it won't work on some platforms, notably Windows. Sorry, fail on my part.)

Ta da:

NSInteger myInteger = 42;
int myInt = (int) myInteger;

NSInteger is nothing more than a 32/64 bit int. (it will use the appropriate size based on what OS/platform you're running)

Setting PYTHONPATH can also help with this problem.

Here is how it can be done on Windows

set PYTHONPATH=.

Default values are only used if the arguments are not specified. In your case you did specify the arguments - both were supplied, with a value of NULL. (Yes, in this case NULL is considered a real value :-). Try:

EXEC TEST()

Share and enjoy.

Addendum: The default values for procedure parameters are certainly buried in a system table somewhere (see the SYS.ALL_ARGUMENTS view), but getting the default value out of the view involves extracting text from a LONG field, and is probably going to prove to be more painful than it's worth. The easy way is to add some code to the procedure:

CREATE OR REPLACE PROCEDURE TEST(X IN VARCHAR2 DEFAULT 'P',
                                 Y IN NUMBER DEFAULT 1)
AS
  varX VARCHAR2(32767) := NVL(X, 'P');
  varY NUMBER          := NVL(Y, 1);
BEGIN
  DBMS_OUTPUT.PUT_LINE('X=' || varX || ' -- ' || 'Y=' || varY);
END TEST;

To make the answer provided by @abourget more complete, the value of scopeValue[field] in the following line of code could be undefined. This would result in an error when setting subfield:

<textarea ng-model="scopeValue[field][subfield]"></textarea>

One way of solving this problem is by adding an attribute ng-focus="nullSafe(field)", so your code would look like the below:

<textarea ng-focus="nullSafe(field)" ng-model="scopeValue[field][subfield]"></textarea>

Then you define nullSafe( field ) in a controller like the below:

$scope.nullSafe = function ( field ) {
  if ( !$scope.scopeValue[field] ) {
    $scope.scopeValue[field] = {};
  }
};

This would guarantee that scopeValue[field] is not undefined before setting any value to scopeValue[field][subfield].

Note: You can't use ng-change="nullSafe(field)" to achieve the same result because ng-change happens after the ng-model has been changed, which would throw an error if scopeValue[field] is undefined.

EDIT: As @Jukka K. Korpela correctly points out, RFC 1738 was updated by RFC 3986. This has expanded and clarified the characters valid for host, unfortunately it's not easily copied and pasted, but I'll do my best.

In first matched order:

host        = IP-literal / IPv4address / reg-name

IP-literal  = "[" ( IPv6address / IPvFuture  ) "]"

IPvFuture   = "v" 1*HEXDIG "." 1*( unreserved / sub-delims / ":" )

IPv6address =         6( h16 ":" ) ls32
                  /                       "::" 5( h16 ":" ) ls32
                  / [               h16 ] "::" 4( h16 ":" ) ls32

Original answer from RFC 1738 specification:

Thus, only alphanumerics, the special characters "$-_.+!*'(),", and reserved characters used for their reserved purposes may be used unencoded within a URL.

^ obsolete since 1998.

An orthodox way to achieve it, is by defining a new function:

public static String join(String joinStr, String... strings) {
    if (strings == null || strings.length == 0) {
        return "";
    } else if (strings.length == 1) {
        return strings[0];
    } else {
        StringBuilder sb = new StringBuilder(strings.length * 1 + strings[0].length());
        sb.append(strings[0]);
        for (int i = 1; i < strings.length; i++) {
            sb.append(joinStr).append(strings[i]);
        }
        return sb.toString();
    }
}

Sample:

String[] array = new String[] { "7, 7, 7", "Bill", "Bob", "Steve",
        "[Bill]", "1,2,3", "Apple ][","~,~" };

String joined;
joined = join(" and ","7, 7, 7", "Bill", "Bob", "Steve", "[Bill]", "1,2,3", "Apple ][","~,~");
joined = join(" and ", array); // same result

System.out.println(joined);

Output:

7, 7, 7 and Bill and Bob and Steve and [Bill] and 1,2,3 and Apple ][ and ~,~

It should be

Intent myIntent = new Intent(this, Katra_home.class);
startActivity(myIntent);

You have to use existing activity context to start new activity, new activity is not created yet, and you cannot use its context or call methods upon it.

not an enclosing class error is thrown because of your usage of this keyword. this is a reference to the current object — the object whose method or constructor is being called. With this you can only refer to any member of the current object from within an instance method or a constructor.

Katra_home.this is invalid construct

If i understand your question right then,

Yes you can set style of individual element if its id or name is available,

e.g.

if id available then u can get control over the element like,

<input type="submit" value="Go" name="goButton">

var v_obj = document.getElementsById('goButton');

v_obj.setAttribute('style','color:red;background:none');

else if name is available then u can get control over the element like,

<input type="submit" value="Go" name="goButton">

var v_obj = document.getElementsByName('goButton');

v_obj.setAttribute('style','color:red;background:none');

I created empty data frame using following code

df = data.frame(id = numeric(0), jobs = numeric(0));

and tried to bind some rows to populate the same as follows.

newrow = c(3, 4)
df <- rbind(df, newrow)

but it started giving incorrect column names as follows

  X3 X4
1  3  4

Solution to this is to convert newrow to type df as follows

newrow = data.frame(id=3, jobs=4)
df <- rbind(df, newrow)

now gives correct data frame when displayed with column names as follows

  id nobs
1  3   4 

Instead of using config files you can use a configuration database with a scoped systemConfig table and add all your settings there.

CREATE TABLE [dbo].[SystemConfig]  
    (  
      [Id] [int] IDENTITY(1, 1)  
                 NOT NULL ,  
      [AppName] [varchar](128) NULL ,  
      [ScopeName] [varchar](128) NOT NULL ,  
      [Key] [varchar](256) NOT NULL ,  
      [Value] [varchar](MAX) NOT NULL ,  
      CONSTRAINT [PK_SystemConfig_ID] PRIMARY KEY NONCLUSTERED ( [Id] ASC )  
        WITH ( PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF,  
               IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON,  
               ALLOW_PAGE_LOCKS = ON ) ON [PRIMARY]  
    )  
ON  [PRIMARY]  

GO  

SET ANSI_PADDING OFF  
GO  

ALTER TABLE [dbo].[SystemConfig] ADD  CONSTRAINT [DF_SystemConfig_ScopeName]  DEFAULT ('SystemConfig') FOR [ScopeName]  
GO 

With such configuration table you can create rows like such:

Then from your your application dal(s) wrapping EF you can easily retrieve the scoped configuration.
If you are not using dal(s) and working in the wire directly with EF, you can make an Entity from the SystemConfig table and use the value depending on the application you are on.

You may do it using xargs if you like, but the main idea is still the same:

find *.txt | xargs -I{} sh -c "cat {}; echo ''" > finalfile.txt

The code says everything:

max@serv$ chmod 777 .

Okay, it doesn't say everything.

In UNIX and Linux, the ability to remove a file is not determined by the access bits of that file. It is determined by the access bits of the directory which contains the file.

Think of it this way -- deleting a file doesn't modify that file. You aren't writing to the file, so why should "w" on the file matter? Deleting a file requires editing the directory that points to the file, so you need "w" on the that directory.

1st answer of Denis is the answer to resolve the trouble. But in fact it is no more a find with several commands in only one exec like the title suggest. To answer the one exec with several commands thing we will have to look for something else to resolv. Here is a example:

Keep last 10000 lines of .log files which has been modified in the last 7 days using 1 exec command using severals {} references

1) see what the command will do on which files:

find / -name "*.log" -a -type f -a -mtime -7 -exec sh -c "echo tail -10000 {} \> fictmp; echo cat fictmp \> {} " \;

2) Do it: (note no more "\>" but only ">" this is wanted)

find / -name "*.log" -a -type f -a -mtime -7 -exec sh -c "tail -10000 {} > fictmp; cat fictmp > {} ; rm fictmp" \;

The simplest thing you can do is use reset.css. It normalizes the default stylesheet across browsers, and coincidentally allows button { vertical-align: middle; } to work just fine. Give it a shot - I use it in virtually all of my projects just to kill little bugs like this.

kieron's answer contains w3schools ref. to which nobody rely , bobince's answer gives link , which actually tells native implementation of IE ,

so here is the original documentation quoted to rightly understand what readystate represents :

The XMLHttpRequest object can be in several states. The readyState attribute must return the current state, which must be one of the following values:

UNSENT (numeric value 0)
The object has been constructed.

OPENED (numeric value 1)
The open() method has been successfully invoked. During this state request headers can be set using setRequestHeader() and the request can be made using the send() method.

HEADERS_RECEIVED (numeric value 2)
All redirects (if any) have been followed and all HTTP headers of the final response have been received. Several response members of the object are now available.

LOADING (numeric value 3)
The response entity body is being received.

DONE (numeric value 4)
The data transfer has been completed or something went wrong during the transfer (e.g. infinite redirects).

Please Read here : W3C Explaination Of ReadyState

You can use this js code. Just change .post-thumb img with your img.

$('.post-thumb img').each(function(){           // Note: {.post-thumb img} is css selector of the image tag
    var t = $(this),
        s = 'url(' + t.attr('src') + ')',
        p = t.parent(),
        d = $('<div></div>');
    t.hide();
    p.append(d);
    d.css({
        'height'                : 260,          // Note: You can change it for your needs
        'background-size'       : 'cover',
        'background-repeat'     : 'no-repeat',
        'background-position'   : 'center',
        'background-image'      : s
    });
});

I don't see why Microsoft didn't handle this. A smart little utility method to deal with this (I had the issue with int, but replacing int with DateTime will be the same effect, could be.....

    public static bool NullableValueTryParse(string text, out int? nInt)
    {
        int value;
        if (int.TryParse(text, out value))
        {
            nInt = value;
            return true;
        }
        else
        {
            nInt = null;
            return false;
        }
    }

Just had the same issue. Wanted to dynamically trigger parametrized downstream jobs based on the outcome of some groovy scripting.

Unfortunately on our Jenkins it's not possible to run System Groovy scripts. Therefore I had to do a small workaround:

1. Run groovy script which creates a properties file where the environment variable to be set is specified

   def props = new File("properties.text")
   if (props.text == 'foo=bar') {
       props.text = 'foo=baz'
   } else {
       props.text = 'foo=bar'
   }
   

2. Use env inject plugin to inject the variable written into this script

   Inject environment variable
   Property file path: properties.text
   

After that I was able to use the variable 'foo' as parameter for the parametrized trigger plugin. Some kind of workaround. But works!

I would definitely advise you to have a look at System.Diagnostics.Stopwatch

And when I looked around for more about Stopwatch I found this site;

Beware of the stopwatch

There mentioned another possibility

Process.TotalProcessorTime

Nothing but plain Javascript (you don't even need a controller):

<div ng-repeat="n in [].constructor(10) track by $index">
    {{ $index }}
</div>

Very useful when mockuping

It's part of the Oracle analytic functions.

Spring cron expression for every day 1:01:am

@Scheduled(cron = "0 1 1 ? * *")

for more information check this information:

https://docs.oracle.com/cd/E12058_01/doc/doc.1014/e12030/cron_expressions.htm

Use the -e argument and the escape character \n:

echo -e "This will generate a next line \nThis new line is the result"

You may just want:

Dim regDate As Date = Date.Today()

I followed the db.dropDatabase() route for a long time, however if you're trying to use this for wiping the database in between test cases you may eventually find problems with index constraints not being honored after the database drop. As a result, you'll either need to mess about with ensureIndexes, or a simpler route would be avoiding the dropDatabase alltogether and just removing from each collection in a loop such as:

db.getCollectionNames().forEach(
  function(collection_name) {
    db[collection_name].remove()
  }
);

In my case I was running this from the command-line using:

mongo [database] --eval "db.getCollectionNames().forEach(function(n){db[n].remove()});"

handles lookinng for something > 1 char long. feel free to increase the parm sizes if you like.

couldnt resist posting

drop function if exists lastIndexOf
go 
create function lastIndexOf(@searchFor varchar(100),@searchIn varchar(500))
returns int
as
begin 

if LEN(@searchfor) > LEN(@searchin) return 0 
declare @r varchar(500), @rsp varchar(100)
select @r = REVERSE(@searchin)
select @rsp = REVERSE(@searchfor)
return len(@searchin) - charindex(@rsp, @r) - len(@searchfor)+1
end 

and tests

select dbo.lastIndexof('greg','greg greg asdflk; greg sadf' )  -- 18
select dbo.lastIndexof('greg','greg greg asdflk; grewg sadf' )  --5
select dbo.lastIndexof(' ','greg greg asdflk; grewg sadf' ) --24

Besides Manuel's way, you can still use the Manifest.

In Android Studio stable, you have to add the following 2 lines to application in the AndroidManifest file:

    android:debuggable="true"
    tools:ignore="HardcodedDebugMode"

The first one will enable debugging of signed APK, and the second one will prevent compile-time error.

After this, you can attach to the process via "Attach debugger to Android process" button.

 var cors = new EnableCorsAttribute("*","*","*");
 config.EnableCors(cors);

 var constraints = new {httpMethod = new HttpMethodConstraint(HttpMethod.Options)};
 config.Routes.IgnoreRoute("OPTIONS", "*pathInfo",constraints);

In my project i am using ajax and i create a web method in my code behind like this

in front

 $("#attachedfiles a").live("click", function () {
            var row = $(this).closest("tr");
            var fileName = $("td", row).eq(0).html();
            $.ajax({
                type: "POST",
                url: "SendEmail.aspx/RemoveFile",
                data: '{fileName: "' + fileName + '" }',
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function () { },
                failure: function (response) {
                    alert(response.d);
                }
            });
            row.remove();
        });  

in code behind

        [WebMethod]
        public static void RemoveFile(string fileName)
        {
            List<HttpPostedFile> files = (List<HttpPostedFile>)HttpContext.Current.Session["Files"];
            files.RemoveAll(f => f.FileName.ToLower().EndsWith(fileName.ToLower()));

            if (System.IO.File.Exists(HttpContext.Current.Server.MapPath("~/Employee/uploads/" + fileName)))
            {
                System.IO.File.Delete(HttpContext.Current.Server.MapPath("~/Employee/uploads/" + fileName));
            }
        }

i think this will help you.

var formValues = {
    firstName: $('#firstName').val(),
    lastName: $('#lastName').val(),
    phone: $('#phoneNumber').val(),
    address: $('#address').val()
};

Note this will contain the values of the elements at the point in time the object literal was interpreted, not when the properties of the object are accessed. You'd need to write a getter for that.

Here's a generic helper function with assumption checking:

func assumeNoError(value interface{}, err error) interface{} {
    if err != nil {
        panic("error encountered when none assumed:" + err.Error())
    }
    return value
}

Since this returns as an interface{}, you'll generally need to cast it back to your function's return type.

For example, the OP's example called Get(1), which returns (Item, error).

item := assumeNoError(Get(1)).(Item)

The trick that makes this possible: Multi-values returned from one function call can be passed in as multi-variable arguments to another function.

As a special case, if the return values of a function or method g are equal in number and individually assignable to the parameters of another function or method f, then the call f(g(parameters_of_g)) will invoke f after binding the return values of g to the parameters of f in order.

This answer borrows heavily from existing answers, but none had provided a simple, generic solution of this form.

Use CompatPadding in CardView Item

You could compare String representations so:

array1.toString() == array2.toString()
array1.toString() !== array3.toString()

but that would also make

array4 = ['1',2,3,4,5]

equal to array1 if that matters to you

The default formatting is not very useful, in my opinion. I prefer ISO8601 as it's sortable, relatively compact and widely recognized:

>> require 'time'
=> true
>> Time.now.utc.iso8601
=> "2011-07-28T23:14:04Z"

You can solve this problem by following few steps:

1) open your terminal window

2) please write following command in your terminal

ssh root@yourIP port

3) Enter root password

4) Now edit your server my.cnf file using below command

nano /etc/my.cnf  

if command is not recognized do this first or try vi then repeat: yum install nano.

OR

  vi /etc/my.cnf 

5) Add the line under the [MYSQLD] section. :

max_allowed_packet=524288000 (obviously adjust size for whatever you need) 
wait_timeout = 100

6) Control + O (save) then ENTER (confirm) then Control + X (exit file)

7) Then restart your mysql server by following command

/etc/init.d/mysql stop
/etc/init.d/mysql start

8) You can verify by going into PHPMyAdmin or opening a SQL command window and executing:

SHOW VARIABLES LIKE 'max_allowed_packet'

This works for me. I hope it should work for you.

I found this version most suitable for all cases. It doesn't remove all whitespaces.

For example "a (test) b" -> "a b"

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim(); "Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();

The pack() method is defined in Window class in Java and it sizes the frame so that all its contents are at or above their preferred sizes.

The problem is caused by your #grid having a width:1140px.

You need to set a min-width:1140px on the body.

This will stop the body from getting smaller than the #grid. Remove width:100% as block level elements take up the available width by default. Live example: http://jsfiddle.net/tw16/LX8R3/

html, body{
    margin:0;
    padding:0;
    min-width: 1140px; /* this is the important part*/
}
#grid-container{
    background:#f8f8f8 url(../images/grid-container-bg.gif) repeat-x top left;
}
#grid{
    width:1140px;
    margin:0px auto;
}

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

You can use this Polyfill in ie and chrome

if (!('contains' in String.prototype)) {
    String.prototype.contains = function (str, startIndex) {
        "use strict";
        return -1 !== String.prototype.indexOf.call(this, str, startIndex);
    };
}

I realize that this is quite an old question and that mongodump/mongorestore is clearly the right way if you want a 100% faithful result, including indexes.

However, I needed a quick and dirty solution that would likely be forwards and backwards compatible between old and new versions of MongoDB, provided there's nothing especially wacky going on. And for that I wanted the answer to the original question.

There are other acceptable solutions above, but this Unix pipeline is relatively short and sweet:

mongo --quiet mydatabase --eval "db.getCollectionNames().join('\n')" | \
grep -v system.indexes | \
xargs -L 1 -I {} mongoexport -d mydatabase -c {} --out {}.json

This produces an appropriately named .json file for each collection.

Note that the database name ("mydatabase") appears twice. I'm assuming the database is local and you don't need to pass credentials but it's easy to do that with both mongo and mongoexport.

Note that I'm using grep -v to discard system.indexes, because I don't want an older version of MongoDB to try to interpret a system collection from a newer one. Instead I'm allowing my application to make its usual ensureIndex calls to recreate the indexes.

I have searched a lot for a solution in which I can compare two array of objects with different attribute names (something like a left outer join). I came up with this solution. Here I used Lodash. I hope this will help you.

var Obj1 = [
    {id:1, name:'Sandra'},
    {id:2, name:'John'},   
];

var Obj2 = [
    {_id:2, name:'John'},
    {_id:4, name:'Bobby'}
];

var Obj3 = lodash.differenceWith(Obj1, Obj2, function (o1, o2) {
    return o1['id'] === o2['_id']
});

console.log(Obj3);
//  {id:1, name:'Sandra'}

Exit code 137 (128+9) indicates that your program exited due to receiving signal 9, which is SIGKILL. This also explains the killed message. The question is, why did you receive that signal?

The most likely reason is probably that your process crossed some limit in the amount of system resources that you are allowed to use. Depending on your OS and configuration, this could mean you had too many open files, used too much filesytem space or something else. The most likely is that your program was using too much memory. Rather than risking things breaking when memory allocations started failing, the system sent a kill signal to the process that was using too much memory.

As I commented earlier, one reason you might hit a memory limit after printing finished counting is that your call to counter.items() in your final loop allocates a list that contains all the keys and values from your dictionary. If your dictionary had a lot of data, this might be a very big list. A possible solution would be to use counter.iteritems() which is a generator. Rather than returning all the items in a list, it lets you iterate over them with much less memory usage.

So, I'd suggest trying this, as your final loop:

for key, value in counter.iteritems():
    writer.writerow([key, value])

Note that in Python 3, items returns a "dictionary view" object which does not have the same overhead as Python 2's version. It replaces iteritems, so if you later upgrade Python versions, you'll end up changing the loop back to the way it was.

I had same error and the mistake was that I had added list and dictionary into the same list (object) and when I used to iterate over the list of dictionaries and use to hit a list (type) object then I used to get this error.

Its was a code error and made sure that I only added dictionary objects to that list and list typed object into the list, this solved my issue as well.

I created a github project Json2Java that does this. https://github.com/inder123/json2java

Json2Java provides customizations such as renaming fields, and creating inheritance hierarchies.

I have used the tool to create some relatively complex APIs:

Gracenote's TMS API: https://github.com/inder123/gracenote-java-api

Google Maps Geocoding API: https://github.com/inder123/geocoding

Take double array as an example, if the initial input values array is not empty, the following code snippet is superior to traditional direct for-loop in time complexity:

public static void resetValues(double[] values) {
  int len = values.length;
  if (len > 0) {
    values[0] = 0.0;
  }
  for (int i = 1; i < len; i += i) {
    System.arraycopy(values, 0, values, i, ((len - i) < i) ? (len - i) : i);
  }
}

Dim and Private work the same, though the common convention is to use Private at the module level, and Dim at the Sub/Function level. Public and Global are nearly identical in their function, however Global can only be used in standard modules, whereas Public can be used in all contexts (modules, classes, controls, forms etc.) Global comes from older versions of VB and was likely kept for backwards compatibility, but has been wholly superseded by Public.

In this state:

The thread is reading and processing rows for a SELECT statement, and sending data to the client.

Because operations occurring during this this state tend to perform large amounts of disk access (reads).

That's why it takes more time to complete and so is the longest-running state over the lifetime of a given query.

When we have a big/lengthy class say more than couple 100 lines of code we can't see everything on Monitor screen, hence we can't see overview (also called document items) of our class. Sometime we want to see overview of our class; its all methods, constants, properties etc at a glance. You can press Ctrl+6 in XCode to see overview of your class. You'll get a pop-up kind of Window aka Jump Bar.

By default, this jump bar doesn't have any buckets/sections. It's just one long list. (Though we can just start typing when jump Bar appears and it will search among jump bar items). Here comes the need of pragma mark

If you want to create sections in your Jump Bar then you can use pragma marks with relevant description. Now refer snapshot attached in question. There 'View lifeCycle' and 'A section dedicated ..' are sections created by pragma marks

With Swift you don't need anymore to check the equality with isEqualToString

You can now use ==

Example:

let x = "hello"
let y = "hello"
let isEqual = (x == y)

now isEqual is true.

You can't set a minimum length on a text field. Otherwise, users wouldn't be able to type in the first five characters.

Your best bet is to validate the input when the form is submitted to ensure that the length is six.

maxlength is not a validation attribute. It is designed to prevent the user from physically typing in more than six characters. The corresponding minlengh is not in scope of the HTML specification, because its implementation would render the textbox unusable.
