You should use ContextWrapper like this:

ContextWrapper cw = new ContextWrapper(context);
File directory = cw.getDir("media", Context.MODE_PRIVATE);

As always, refer to documentation, ContextWrapper has a lot to offer.

You probably want this (to make it like a normal CSS background-image declaration):

$('myObject').css('background-image', 'url(' + imageUrl + ')');

I think that maybe it is because you are declaring a variable that you already declared:

var Name = new Array(6);
//...
var Name[0] = Name_cell.getValue();  //  <-- Here's the issue: 'var'

I think this should be like this:

var Name = new Array(6);
//...
Name[0] = Name_cell.getValue();

Tell me if it works! ;)

If you have an Order class, adding a property that references another class in your model, for instance Customer should be enough to let EF know there's a relationship in there:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    public virtual Customer Customer { get; set; }
}

You can always set the FK relation explicitly:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    [ForeignKey("Customer")]
    public string CustomerID { get; set; }
    public virtual Customer Customer { get; set; }
}

The ForeignKeyAttribute constructor takes a string as a parameter: if you place it on a foreign key property it represents the name of the associated navigation property. If you place it on the navigation property it represents the name of the associated foreign key.

What this means is, if you where to place the ForeignKeyAttribute on the Customer property, the attribute would take CustomerID in the constructor:

public string CustomerID { get; set; }
[ForeignKey("CustomerID")]
public virtual Customer Customer { get; set; }

EDIT based on Latest Code You get that error because of this line:

[ForeignKey("Parent")]
public Patient Patient { get; set; }

EF will look for a property called Parent to use it as the Foreign Key enforcer. You can do 2 things:

1) Remove the ForeignKeyAttribute and replace it with the RequiredAttribute to mark the relation as required:

[Required]
public virtual Patient Patient { get; set; }

Decorating a property with the RequiredAttribute also has a nice side effect: The relation in the database is created with ON DELETE CASCADE.

I would also recommend making the property virtual to enable Lazy Loading.

2) Create a property called Parent that will serve as a Foreign Key. In that case it probably makes more sense to call it for instance ParentID (you'll need to change the name in the ForeignKeyAttribute as well):

public int ParentID { get; set; }

In my experience in this case though it works better to have it the other way around:

[ForeignKey("Patient")]
public int ParentID { get; set; }

public virtual Patient Patient { get; set; }

Manually cast the sender to the type of your custom control, and then use it to delete or disable etc. Eg, something like this:

private void myCustomControl_Click(object sender, EventArgs e)
{
  ((MyCustomControl)sender).DoWhatever();
}

The 'sender' is just the object that was actioned (eg clicked).

The event args is subclassed for more complex controls, eg a treeview, so that you can know more details about the event, eg exactly where they clicked.

As suggested here by @0x7fffffff, if you have UINavigationController it can be easier to do:

YourViewController *rootController =
    (YourViewController *)
        [self.navigationController.viewControllers objectAtIndex: 0];

The code in the answer above returns UINavigation controller (if you have it) and if this is what you need, you can use self.navigationController.

In my case you should put the function in $(document).ready

$(document).ready(function () {
    $('div#page').on('scroll', function () {
     ...
    });
});

If we're talking about data.frame, then you should ask yourself are the variables of the same type? If that's the case, you can use rapply, or unlist, since data.frames are lists, deep down in their souls...

 data(mtcars)
 unlist(mtcars)
 rapply(mtcars, c) # completely stupid and pointless, and slower

You should declare Environment Variable for PHP in path, so you could use like this:

C:\Path\to\somewhere>php cli.php

You can do it like this

you can add the 1px border to just the sides and bottom of each row. the first value is the top border, the second is the right border, the third is the bottom border, and the fourth is the left border.

div.row {
  border: 0px 1px 1px 1px solid;
}

You can use

//send message only to sender-client

socket.emit('message', 'check this');

//or you can send to all listeners including the sender

io.emit('message', 'check this');

//send to all listeners except the sender

socket.broadcast.emit('message', 'this is a message');

//or you can send it to a room

socket.broadcast.to('chatroom').emit('message', 'this is the message to all');

When you only need to check for equality, you can also simply use the in operator to do a membership test in a sequence of accepted elements:

if message.value[0] in ('/', '\\'):
    do_stuff()

Use ast.literal_eval to evaluate Python literals. However, what you have is JSON (note "true" for example), so use a JSON deserializer.

>>> import json
>>> s = """{"id":"123456789","name":"John Doe","first_name":"John","last_name":"Doe","link":"http:\/\/www.facebook.com\/jdoe","gender":"male","email":"jdoe\u0040gmail.com","timezone":-7,"locale":"en_US","verified":true,"updated_time":"2011-01-12T02:43:35+0000"}"""
>>> json.loads(s)
{u'first_name': u'John', u'last_name': u'Doe', u'verified': True, u'name': u'John Doe', u'locale': u'en_US', u'gender': u'male', u'email': u'[email protected]', u'link': u'http://www.facebook.com/jdoe', u'timezone': -7, u'updated_time': u'2011-01-12T02:43:35+0000', u'id': u'123456789'}

To get the most recent tag (example output afterwards):

git describe --tags --abbrev=0   # 0.1.0-dev

To get the most recent tag, with the number of additional commits on top of the tagged object & more:

git describe --tags              # 0.1.0-dev-93-g1416689

To get the most recent annotated tag:

git describe --abbrev=0

Using MAMP I changed the host=localhost to host=127.0.0.1. But a new issue came "connection refused"

Solved this by putting 'port' => '8889', in 'Datasources' => [

I already tried all suggestion posted in here, yet I'm still getting the errno 13,

I'm using Windows and my python version is 3.7.3

After 5 hours of trying to solve it, this step worked for me:

I try to open the command prompt by run as administrator

I guess it depends on your role

For me as a developer:

• Merge statement
• Reporting Services improvement
• Date/time changes

Edit, late update, after using it

• filtered indexes
• table valued parameters
• Reporting Services without IIS

I have been in this position, especially with new hardware. I suggest you write a little hex dump routine of your own. You will be able to see the data, and the addresses they are at, shown all together. It's good practice and a confidence builder.

More simple in Laravel 5.7 and 5.8

{{ Request()->parameter }}

Use That :

$(selector).trigger("change");

OR

$('#id').trigger("click");

OR

$('.class').trigger(event);

Trigger can be any event that javascript support.. Hope it's easy to understandable to all of You.

Simply, add a plus sign before the text value

var newValue = +currentValue + 1;

I know this post is old, but in case someone is searching google i think i should mention what fixed my problem. After the 3 steps from above the error message was gone but the screen still stayed black and opening an .apk got stuck on file transfer. It had something to do with a VPN application (in my case Hamachi). I just closed it and then the emulator ran fine. This post prompted me to do so: https://groups.google.com/forum/#!searchin/genymotion-users/network/genymotion-users/QAX_UrAzEn0/o947IXpsDuIJ

First of all, try toObject() instead of toJSON() maybe?

Secondly, you'll need to call it on the actual documents and not the array, so maybe try something more annoying like this:

var flatUsers = users.map(function() {
  return user.toObject();
})
return res.end(JSON.stringify(flatUsers));

It's a guess, but I hope it helps

SELECT count(*)         -- or count(myCol)
FROM   <table name>     -- replace <table name> with your table
WHERE  myCol = true;

Here's a way with Windowing Function:

SELECT DISTINCT *, count(*) over(partition by myCol)
FROM   <table name>;

-- Outputs:
-- --------------
-- myCol | count
-- ------+-------
--  f    |  2
--  t    |  3
--       |  1

You can use the following function to enqueue script or style from plugin.

function my_enqueued_assets() {
    wp_enqueue_script('my-js-file', plugin_dir_url(__FILE__) . '/js/script.js', '', time());
    wp_enqueue_style('my-css-file', plugin_dir_url(__FILE__) . '/css/style.css', '', time());
}
add_action('wp_enqueue_scripts', 'my_enqueued_assets');

try putting

ErrorDocument 404 /(root directory)/(error file) 

in .htaccess file.

Do this for any error but substitute 404 for your error.

You can simply restore these database backup files using native SQL Server methods, or you can use ApexSQL Restore tool to quickly virtually attach the files and access them as fully restored databases.

We experienced this on a HostGator account (who place inode limits on all their hosting) following a spam attack. It left vast numbers of queue records in /root/.cpanel/comet. If this happens and you find you have no free inodes, you can run this cpanel utility through shell:

/usr/local/cpanel/bin/purge_dead_comet_files

I just wanted to echo @Luann's comment as I use this approach always.

Just right click on the table > Script table as > Select to > New Query window.

You will see the select query. Just take out the column you want to exclude and you have your preferred select query.

both seem to be working.

I've found that if the input has no name (e.g. the name attribute is not set), the browser can't autocomplete the field. I know this is not a solution for everyone, but if you submit your form through AJAX, you may try this.

My problem is related to many of the other answers, but a little bit different reason for needing to make the change... I was trying to convert an Activity to a Fragment. So I moved the inflate code from onCreate to onCreateView, but I forgot to convert from setContentView to the inflate method, and the same IllegalStateException brought me to this page.

I changed this:

binding = DataBindingUtil.setContentView(requireActivity(), R.layout.my_fragment)

to this:

binding = DataBindingUtil.inflate(inflater, R.layout.my_fragment, container, false)

That solved the problem.

If you are trying to cache the tiles that Google serves, that may be a violation of Google's Terms of Service (unless, under certain circumstances, if you've purchased their enterprise Maps API Premier). That's why gmapcatcher has it crossed off their list. See http://code.google.com/p/gmapcatcher/issues/detail?id=210.

At the gmapcatcher URL above, you will also find a shell script that can download tiles (or so its author says).

There are also other projects that try to make Google Maps available offline:

http://code.google.com/p/ogmaps/

http://code.google.com/p/gmapoffline/

Lastly, if Google Earth can meet your needs, then you can use that. Offline usage of Google Earth requires a Google Earth Enterprise license according to http://www.google.com/permissions/geoguidelines.html.

Note that the preceding page also says: "You may not scrape or otherwise export Content from Google Maps or Earth or save it for offline use." So if you try to cache tiles, that will almost certainly be considered (by Google, anyway) a violation of the Terms of Service.

<input size="45" type="text" name="name">

The "size" specifies the visible width in characters of the element input.

You can also use the height and width from css.

<input type="text" name="name" style="height:100px; width:300px;">

Globbing uses brackets, hence the need to escape them with a slash \. Alternatively, the following command-line switch will disable globbing:

--globoff (or the short-option version: -g)

Ex:

curl --globoff https://www.google.com?test[]=1

If you want to clear all radio buttons in the DOM:

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

but i only wanted the for statement to be attached to the if statement, not the else if statements as well.

Well get rid of the else then. If the else if is not supposed to be part of the for then write it as:

           for(int i=0; i<something_in_the_array.length;i++)
                if(whatever_value==(something_in_the_array[i]))
                {
                    value=2;
                    break;
                }

           if(whatever_value==2)
           {
                value=3;
                break;  // redundant now
           }

           else if(whatever_value==3)
           {
                value=4;
                break;  // redundant now
           }

Having said that:

• it is not at all clear what you are really trying to do here,
• not having the else part in the loop doesn't seem to make a lot of sense here,
• a lot of people (myself included) think it is to always use braces ... so that people don't get tripped up by incorrect indentation when reading your code. (And in this case, it might help us figure out what you are really trying to do here ...)

Finally, braces are less obtrusive if you put the opening brace on the end of the previous line; e.g.

  if (something) {
     doSomething();
  }

rather than:

  if (something) 
  {
     doSomething();
  }

In case someone wants to actually knock out SQL statement logging (without changing logging level, and while keeping the logging from their AR models):

The line that writes to the log (in Rails 3.2.16, anyway) is the call to debug in lib/active_record/log_subscriber.rb:50.

That debug method is defined by ActiveSupport::LogSubscriber.

So we can knock out the logging by overwriting it like so:

module ActiveSupport
  class LogSubscriber
    def debug(*args, &block)
    end
  end
end

The only solution that work for me was put npx tsc -v or for the compiling npx tsc salida.ts

"salida.ts" is the name of the file

Use this code to setup your mongodb connection:

var mongoose = require('mongoose');

var mongoURI = "mongodb://localhost:27017/test";
var MongoDB = mongoose.connect(mongoURI).connection;
MongoDB.on('error', function(err) { console.log(err.message); });
MongoDB.once('open', function() {
  console.log("mongodb connection open");
});

Make sure mongod is running while you start the server. Are you using Express or just a simple node.js server? What is the error message you get with the above code?

another way is

nullif(trim(stringExpression),'') is not null

This is not quite the answer to this question, but it may be useful for some: as @SWeko said, thanks to covariance and contravariance, List<X> can not be cast in List<Y>, but List<X> can be cast into IEnumerable<Y>, and even with implicit cast.

Example:

List<Y> ListOfY = new List<Y>();
List<X> ListOfX = (List<X>)ListOfY; // Compile error

but

List<Y> ListOfY = new List<Y>();
IEnumerable<X> EnumerableOfX = ListOfY;  // No issue

The big advantage is that it does not create a new list in memory.

Not the most beautiful way of doing it I guess:

git log --pretty=oneline | wc -l

This gives you a number then

git log HEAD~<The number minus one>

One very easy way to do it is use the following command:

set /p mytextfile=< %pathtotextfile%\textfile.txt
echo %mytextfile%

This will only display the first line of text in a text file. The other way you can do it is use the following command:

type %pathtotextfile%\textfile.txt

This will put all the data in the text file on the screen. Hope this helps!

Check out the percent function from the formattable package:

library(formattable)
x <- c(0.23, 0.95, 0.3)
percent(x)
[1] 23.00% 95.00% 30.00%

I've found this to be a pain in javascript. Check out this link that helped me. Have you ever thought of extending the date object.

You need to convert the String object into an array of char using the toCharArray() method of the String class:

String str = "xyz";
char arr[] = str.toCharArray(); // convert the String object to array of char

// iterate over the array using the for-each loop.       
for(char c: arr){
    System.out.println(c);
}

You also need to include the Log4J JAR file in the classpath.

Note that slf4j-log4j12-1.6.4.jar is only an adapter to make it possible to use Log4J via the SLF4J API. It does not contain the actual implementation of Log4J.

Use

<ScrollView 
 onMomentumScrollEnd={(event) => this.getscrollposition(event)} 
 scrollEventThrottle={16}>

Show Position

getscrollposition(e) {console.log('scroll y ', e.nativeEvent.contentOffset.y);}

Get the PID of the task and kill it.

lsof -ti:8080 | xargs kill

I found this url to be very useful: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/2cdcab2e-ea49-4fd5-b2b8-13824ab4619b/help-server-not-listening-on-1433

In particular, my problem was that I did not enable the TCP/IP in Sql Server Configuration Manager->SQL Server Network Configuration->Protocols for SQLEXPRESS.

Once you open it, you have to go to the IP Addresses tab and for me, changing IPAll to TCP port 1433 and deleting the TCP Dynamic Ports value worked.

Follow the other steps to make sure 1433 is listening (Use netstat -an to make sure 0.0.0.0:1433 is LISTENING.), and that you can telnet to the port from the client machine.

Finally, I second the suggestion to remove the \SQLEXPRESS from the connection.

EDIT: I should note I am using SQL Server 2014 Express.

For completeness, echo $(__git_ps1), on Linux at least, should give you the name of the current branch surrounded by parentheses.

This may be useful is some scenarios as it is not a Git command (while depending on Git), notably for setting up your Bash command prompt to display the current branch.

For example:

/mnt/c/git/ConsoleApp1 (test-branch)> echo $(__git_ps1)
(test-branch)
/mnt/c/git/ConsoleApp1 (test-branch)> git checkout master
Switched to branch 'master'
/mnt/c/git/ConsoleApp1 (master)> echo $(__git_ps1)
(master)
/mnt/c/git/ConsoleApp1 (master)> cd ..
/mnt/c/git> echo $(__git_ps1)

/mnt/c/git>

You can use the following nginx configuration example:

upstream adminhost {
  server adminhostname:8080;
}

server {
  listen 80;

  location ~ ^/admin/(.*)$ {
    proxy_pass http://adminhost/$1$is_args$args;
    proxy_redirect off;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Host $server_name;
  }
}

Avro is a row-based storage format for Hadoop.

Parquet is a column-based storage format for Hadoop.

If your use case typically scans or retrieves all of the fields in a row in each query, Avro is usually the best choice.

If your dataset has many columns, and your use case typically involves working with a subset of those columns rather than entire records, Parquet is optimized for that kind of work.

Lombok Issue #78 references this page https://www.donneo.de/2015/09/16/lomboks-builder-annotation-and-inheritance/ with this lovely explanation:

@AllArgsConstructor 
public class Parent {   
     private String a; 
}

public class Child extends Parent {
  private String b;

  @Builder
  public Child(String a, String b){
    super(a);
    this.b = b;   
  } 
} 

As a result you can then use the generated builder like this:

Child.builder().a("testA").b("testB").build(); 

The official documentation explains this, but it doesn’t explicitly point out that you can facilitate it in this way.

I also found this works nicely with Spring Data JPA.

' is not part of the HTML 4 standard.

" is, though, so is fine to use.

After spending some time on Serialization, I find that, we should not generate serialVersionUID with some random value, we should give it a meaningful value.

Here is a details comment on this. I am coping the comment here.

Actually, you should not be "generating" serial version UIDs. It is a dumb "feature" that stems from the general misunderstanding of how that ID is used by Java. You should be giving these IDs meaningful, readable values, e.g. starting with 1L, and incrementing them each time you think the new version of the class should render all previous versions (that might be previously serialized) obsolete. All utilities that generate such IDs basically do what the JVM does when the ID is not defined: they generate the value based on the content of the class file, hence coming up with unreadable meaningless long integers. If you want each and every version of your class to be distinct (in the eyes of the JVM) then you should not even specify the serialVersionUID value isnce the JVM will produce one on the fly, and the value of each version of your class will be unique. The purpose of defining that value explicitly is to tell the serialization mechanism to treat different versions of the class that have the same SVUID as if they are the same, e.g. not to reject the older serialized versions. So, if you define the ID and never change it (and I assume that's what you do since you rely on the auto-generation, and you probably never re-generate your IDs) you are ensuring that all - even absolutely different - versions of your class will be considered the same by the serialization mechanism. Is that what you want? If not, and if you indeed want to have control over how your objects are recognized, you should be using simple values that you yourself can understand and easily update when you decide that the class has changed significantly. Having a 23-digit value does not help at all.

Hope this helps. Good luck.

ALLOW-FROM is not supported in Chrome or Safari. See MDN article: https://developer.mozilla.org/en-US/docs/Web/HTTP/X-Frame-Options

You are already doing the work to make a custom header and send it with the correct data, can you not just exclude the header when you detect it is from a valid partner and add DENY to every other request? I don't see the benefit of AllowFrom when you are already dynamically building the logic up?

As you're generating the image dynamically, set the onload property before the src.

var img = new Image();
img.onload = function () {
   alert("image is loaded");
}
img.src = "img.jpg";

Fiddle - tested on latest Firefox and Chrome releases.

You can also use the answer in this post, which I adapted for a single dynamically generated image:

var img = new Image();
// 'load' event
$(img).on('load', function() {
  alert("image is loaded");
});
img.src = "img.jpg";

Fiddle

There's a function in the standard-library for this: itertools.permutations.

import itertools
list(itertools.permutations([1, 2, 3]))

If for some reason you want to implement it yourself or are just curious to know how it works, here's one nice approach, taken from http://code.activestate.com/recipes/252178/:

def all_perms(elements):
    if len(elements) <=1:
        yield elements
    else:
        for perm in all_perms(elements[1:]):
            for i in range(len(elements)):
                # nb elements[0:1] works in both string and list contexts
                yield perm[:i] + elements[0:1] + perm[i:]

A couple of alternative approaches are listed in the documentation of itertools.permutations. Here's one:

def permutations(iterable, r=None):
    # permutations('ABCD', 2) --> AB AC AD BA BC BD CA CB CD DA DB DC
    # permutations(range(3)) --> 012 021 102 120 201 210
    pool = tuple(iterable)
    n = len(pool)
    r = n if r is None else r
    if r > n:
        return
    indices = range(n)
    cycles = range(n, n-r, -1)
    yield tuple(pool[i] for i in indices[:r])
    while n:
        for i in reversed(range(r)):
            cycles[i] -= 1
            if cycles[i] == 0:
                indices[i:] = indices[i+1:] + indices[i:i+1]
                cycles[i] = n - i
            else:
                j = cycles[i]
                indices[i], indices[-j] = indices[-j], indices[i]
                yield tuple(pool[i] for i in indices[:r])
                break
        else:
            return

And another, based on itertools.product:

def permutations(iterable, r=None):
    pool = tuple(iterable)
    n = len(pool)
    r = n if r is None else r
    for indices in product(range(n), repeat=r):
        if len(set(indices)) == r:
            yield tuple(pool[i] for i in indices)

$ git log --diff-filter=D --summary  | grep "delete" | sort

you would want to use php to write out a meta tag.

<meta http-equiv="refresh" content="5;url=http://www.yoursite.com">

It is not recommended but it is possible. The 5 in this example is the number of seconds before it refreshes.

Yes, it is possible. You have to do something like this:

if(isset($_POST['submit']))
{
  $type_id = ($_POST['type_id'] == '' ? "null" : "'".$_POST['type_id']."'");
  $sql = "INSERT INTO `table` (`type_id`) VALUES (".$type_id.")";
}

It checks if the $_POST['type_id'] variable has an empty value. If yes, it assign NULL as a string to it. If not, it assign the value with ' to it for the SQL notation

you have to be careful here not to miss the dates when in the loop a better solution would be.

this gives you the first date of startdate and use it in the loop before incrementing it and it will process all the dates including the last date of enddate hence <= enddate.

so the above answer is the correct one.

while (startdate <= enddate)
{
    // do something with the startdate
    startdate = startdate.adddays(interval);
}

Here's a way to bake this functionality right into all DOM elements:

HTMLElement.prototype.removeClass = function(remove) {
    var newClassName = "";
    var i;
    var classes = this.className.split(" ");
    for(i = 0; i < classes.length; i++) {
        if(classes[i] !== remove) {
            newClassName += classes[i] + " ";
        }
    }
    this.className = newClassName;
}

Here is from me to share

Option 1 - counting from same domain from different table

select distinct(select count(*) from domain1.table1) "count1", (select count(*) from domain1.table2) "count2" 
from domain1.table1, domain1.table2;

Option 2 - counting from different domain for same table

select distinct(select count(*) from domain1.table1) "count1", (select count(*) from domain2.table1) "count2" 
from domain1.table1, domain2.table1;

Option 3 - counting from different domain for same table with "union all" to have rows of count

select 'domain 1'"domain", count(*) 
from domain1.table1 
union all 
select 'domain 2', count(*) 
from domain2.table1;

Enjoy the SQL, I always do :)

On GitLab, you may have to set your branch to unprotected before doing this. You can do this in [repo] > Settings > Repository > Protected Branches. Then the method from Mark's answer works.

git reset --hard <commit-hash>
git push -f origin master

I came up with 4 methods to achieve the results. Here is demo

Method 1:

#a {
    margin-right: auto;
}

Method 2:

#a {
    flex-grow: 1;
}

Method 3:

#b {
    margin-left: auto;
}

Method 4:

#container {
    justify-content: space-between;
}

The following code snippet is doing it for me (lat and lng are doubles declared above this bit):

Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);

You’re looking for urllib.parse.urlencode

import urllib.parse

params = {'username': 'administrator', 'password': 'xyz'}
encoded = urllib.parse.urlencode(params)
# Returns: 'username=administrator&password=xyz'

You could also set an inputMask:

QLineEdit.setInputMask("9")

This allows the user to type only one digit ranging from 0 to 9. Use multiple 9's to allow the user to enter multiple numbers. See also the complete list of characters that can be used in an input mask.

(My answer is in Python, but it should not be hard to transform it to C++)

One thing that should be considered is licensing.

Notepad++ is free (as in speech and as in beer) for perpetual use, released under the GPL license, whereas Sublime Text 2 requires a license.

To quote the Sublime Text 2 website:

..a license must be purchased for continued use. There is currently no enforced time limit for the evaluation.

The same is now true of Sublime Text 3, and a paid upgrade will be needed for future versions.

Upgrade Policy A license is valid for Sublime Text 3, and includes all point updates, as well as access to prior versions (e.g., Sublime Text 2). Future major versions, such as Sublime Text 4, will be a paid upgrade.

This licensing requirement is still correct as of Dec 2019.

 public static <E> E[] arrayListToTypedArray(List<E> list) {

    if (list == null) {
      return null;
    }
    int noItems = list.size();
    if (noItems == 0) {
      return null;
    }

    E[] listAsTypedArray;
    E typeHelper = list.get(0);

    try {
      Object o = Array.newInstance(typeHelper.getClass(), noItems);
      listAsTypedArray = (E[]) o;
      for (int i = 0; i < noItems; i++) {
        Array.set(listAsTypedArray, i, list.get(i));
      }
    } catch (Exception e) {
      return null;
    }

    return listAsTypedArray;
  }

The javadoc says this:

"Returns an immutable list containing only the specified object. The returned list is serializable."

You ask:

Why would I want to have a separate method to do that?

Primarily as a convenience ... to save you having to write a sequence of statements to:

• create an empty list object
• add an element to it, and
• wrap it with an immutable wrapper.

It may also be a bit faster and/or save a bit of memory, but it is unlikely that these small savings will be significant. (An application that creates vast numbers of singleton lists is unusual to say the least.)

How does immutability play a role here?

It is part of the specification of the method; see above.

Are there any special useful use-cases for this method, rather than just being a convenience method?

Clearly, there are use-cases where it is convenient to use the singletonList method. But I don't know how you would (objectively) distinguish between an ordinary use-case and a "specially useful" one ...

You can overwrite your default activity animation and it perform better than overridePendingTransition. I use this solution that work for every android version. Just copy paste 4 files and add a 4 lines style as below:

Create a "CustomActivityAnimation" and add this to your base Theme by "windowAnimationStyle".

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorPrimary</item>
    <item name="android:windowAnimationStyle">@style/CustomActivityAnimation</item>

</style>

<style name="CustomActivityAnimation" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">@anim/slide_in_right</item>
    <item name="android:activityOpenExitAnimation">@anim/slide_out_left</item>
    <item name="android:activityCloseEnterAnimation">@anim/slide_in_left</item>
    <item name="android:activityCloseExitAnimation">@anim/slide_out_right</item>
</style>

Then Create anim folder under res folder and then create this four animation files into anim folder:

slide_in_right.xml

<?xml version="1.0" encoding="utf-8"?>

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

slide_out_left.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="0" android:toXDelta="-100%p"
        android:duration="@android:integer/config_mediumAnimTime"/>
</set>

slide_in_left.xml

<?xml version="1.0" encoding="utf-8"?>

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate android:fromXDelta="-100%p" android:toXDelta="0"

</set>

slide_out_right.xml

    <translate android:fromXDelta="0" android:toXDelta="100%p"
        android:duration="@android:integer/config_mediumAnimTime"/>
</set>

This is called the "shape" in NumPy, and can be requested via the .shape attribute:

>>> a = zeros((2, 5))
>>> a.shape
(2, 5)

If you prefer a function, you could also use numpy.shape(a).

You can use pandas.Dataframe.isin.

pandas.Dateframe.isin will return boolean values depending on whether each element is inside the list a or not. You then invert this with the ~ to convert True to False and vice versa.

import pandas as pd

a = ['2015-01-01' , '2015-02-01']

df = pd.DataFrame(data={'date':['2015-01-01' , '2015-02-01', '2015-03-01' , '2015-04-01', '2015-05-01' , '2015-06-01']})

print(df)
#         date
#0  2015-01-01
#1  2015-02-01
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

df = df[~df['date'].isin(a)]

print(df)
#         date
#2  2015-03-01
#3  2015-04-01
#4  2015-05-01
#5  2015-06-01

Yes, You can use gcc to compile your asm code. Use -c for compilation like this:

gcc -c file.S -o file.o

This will give object code file named file.o. To invoke linker perform following after above command:

gcc file.o -o file

As they have already indicated to you, you should use 'backticks'.

The alternative proposed $(command) works as well, and it also easier to read, but note that it is valid only with Bash or KornShell (and shells derived from those), so if your scripts have to be really portable on various Unix systems, you should prefer the old backticks notation.

Selecting all the text you wish to format and pressing CtrlK, CtrlF shortcut applies the indenting and space formatting.

As specified in the Formatting pane (of the language being used) in the Text Editor section of the Options dialog.

See VS Shortcuts for more.

While results will most likely be the same (no border), the 0 and none are technically addressing different things.

0 addresses border width and none addresses border style. Obviously a border of 0 width is nonexistent so will therefore have no style.

However, if later on in your stylesheet you intend to override this, you would naturally specifically address one or the other. If I now wanted a 3px border, that would be directly overriding border: 0 in regards to width. If I now wanted a dotted border, that would be directly overriding border: none in regards to styling.

This cannot be done with CMake. You have to generate two separate build folders. One for the x86 NMake build and one for the x64 NMake build. You cannot generate a single Visual Studio project covering both architectures with CMake, either.

To build Visual Studio projects from the command line for both 32-bit and 64-bit without starting a Visual Studio command prompt, use the regular Visual Studio generators.

For CMake 3.13 or newer, run the following commands:

cmake -G "Visual Studio 16 2019" -A Win32 -S \path_to_source\ -B "build32"
cmake -G "Visual Studio 16 2019" -A x64 -S \path_to_source\ -B "build64"
cmake --build build32 --config Release
cmake --build build64 --config Release

For earlier versions of CMake, run the following commands:

mkdir build32 & pushd build32
cmake -G "Visual Studio 15 2017" \path_to_source\
popd
mkdir build64 & pushd build64
cmake -G "Visual Studio 15 2017 Win64" \path_to_source\
popd
cmake --build build32 --config Release
cmake --build build64 --config Release

CMake generated projects that use one of the Visual Studio generators can be built from the command line with using the option --build followed by the build directory. The --config option specifies the build configuration.

The other answers here are correct - use reverse DNS lookups. If you want to do it via a scripting language (Python, Perl) you could use the gethostbyaddr API.

Try BeanComparator from Apache Commons.

import org.apache.commons.beanutils.BeanComparator;


BeanComparator fieldComparator = new BeanComparator("fruitName");
Collections.sort(fruits, fieldComparator);

I notice you have some C++ questions in your profile. If you understand the concept of multiple-inheritance from C++ (referring to classes that inherit characteristics from more than one other class), Java does not allow this, but it does have keyword interface, which is sort of like a pure virtual class in C++. As mentioned by lots of people, you extend a class (and you can only extend from one), and you implement an interface -- but your class can implement as many interfaces as you like.

Ie, these keywords and the rules governing their use delineate the possibilities for multiple-inheritance in Java (you can only have one super class, but you can implement multiple interfaces).

If you want the file from a particular commit (any branch) , say 06f8251f

git checkout 06f8251f path_to_file

for example , in windows:

git checkout 06f8251f C:\A\B\C\D\file.h

You can simply use shell commands. If you want to suppress echoing the output, use the "@" sign. For example:

clean:
    @if [ "test" = "test" ]; then\
        echo "Hello world";\
    fi

Note that the closing ";" and "\" are necessary.

The only way to do this is via various CSS hacks, which will make your page much more likely to fail on the next browser updates. If anything, it will be LESS safe than using a js-browser sniffer.

Another option that may be useful is a dedicated HTTP debugging tool. There's a few available, I'd suggest HTTP Toolkit: an open-source project I've been working on (yeah, I might be biased) to solve this same problem for myself.

The main difference is usability & power. The Chrome dev tools are good for simple things, and I'd recommend starting there, but if you're struggling to understand the information there, and you need either more explanation or more power then proper focused tools can be useful!

For this case, it'll show you the full POST body you're looking for, with a friendly editor and highlighting (all powered by VS Code) so you can dig around. It'll give you the request & response headers of course, but with extra info like docs from MDN (the Mozilla Developer Network) for every standard header and status code you can see.

A picture is worth a thousand StackOverflow answers:

The accepted answer is not ideal, so I decided to add my 2 cents

timeStamp.toLocalDateTime().toLocalDate();

is a bad solution in general, I'm not even sure why they added this method to the JDK as it makes things really confusing by doing an implicit conversion using the system timezone. Usually when using only java8 date classes the programmer is forced to specify a timezone which is a good thing.

The good solution is

timestamp.toInstant().atZone(zoneId).toLocalDate()

Where zoneId is the timezone you want to use which is typically either ZoneId.systemDefault() if you want to use your system timezone or some hardcoded timezone like ZoneOffset.UTC

The general approach should be

1. Break free to the new java8 date classes using a class that is directly related, e.g. in our case java.time.Instant is directly related to java.sql.Timestamp, i.e. no timezone conversions are needed between them.
2. Use the well-designed methods in this java8 class to do the right thing. In our case atZone(zoneId) made it explicit that we are doing a conversion and using a particular timezone for it.

This tutorial is a very good one for pandas slicing. Make sure you check it out. Onto some snippets... To slice a dataframe with a condition, you use this format:

>>> df[condition]

This will return a slice of your dataframe which you can index using iloc. Here are your examples:

1. Get first row where A > 3 (returns row 2)

   >>> df[df.A > 3].iloc[0]
   A    4
   B    6
   C    3
   Name: 2, dtype: int64
   

If what you actually want is the row number, rather than using iloc, it would be df[df.A > 3].index[0].

2. Get first row where A > 4 AND B > 3:

   >>> df[(df.A > 4) & (df.B > 3)].iloc[0]
   A    5
   B    4
   C    5
   Name: 4, dtype: int64
   

3. Get first row where A > 3 AND (B > 3 OR C > 2) (returns row 2)

   >>> df[(df.A > 3) & ((df.B > 3) | (df.C > 2))].iloc[0]
   A    4
   B    6
   C    3
   Name: 2, dtype: int64
   

Now, with your last case we can write a function that handles the default case of returning the descending-sorted frame:

>>> def series_or_default(X, condition, default_col, ascending=False):
...     sliced = X[condition]
...     if sliced.shape[0] == 0:
...         return X.sort_values(default_col, ascending=ascending).iloc[0]
...     return sliced.iloc[0]
>>> 
>>> series_or_default(df, df.A > 6, 'A')
A    5
B    4
C    5
Name: 4, dtype: int64

As expected, it returns row 4.

I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.

To answer the question in the header: To install make in ubuntu you have to install build-essentials

sudo apt-get install build-essential

I know this thread is old but I recently ran into a problem with JSToolNPP not being compatible with my newly updated N++, I did find a replacement that seems to work. http://sourceforge.net/projects/nppjsonviewer/

Use at your own risk, ofc. (standard disclaimer from me when linking anything outside the SExchange, fyi)

I also faced it and encorrected it like below successfully.

File > Settings > Build, Execution, Deployment > Gradle > Use local gradle distribution

Set the home path as : C:/Program Files/Android/Android Studio/gradle/gradle-version

You may need to upgrade your gradle version.

setState() is usually asynchronous, which means that at the time you console.log the state, it's not updated yet. Try putting the log in the callback of the setState() method. It is executed after the state change is complete:

this.setState({ dealersOverallTotal: total }, () => {
  console.log(this.state.dealersOverallTotal, 'dealersOverallTotal1');
}); 

npm module has to be bundeled inside your nodejs package and upload to AWS Lambda Layers as zip, then you would need to refer to your module/js as below and use available methods from it. const mymodule = require('/opt/nodejs/MyLogger');

The newer android phones in the market like HTC one, Xperia Z etc have resolutions in the >480dpi range, putting them in the new xxhdpi class as well. The new assets might be useful for them too.

Adding on to the main response that recommends the usage of WpfAnimatedGif, you must add the following lines in the end if you are swapping an image with a Gif to ensure the animation actually executes:

ImageBehavior.SetRepeatBehavior(img, new RepeatBehavior(0));
ImageBehavior.SetRepeatBehavior(img, RepeatBehavior.Forever);

So your code will look like:

var image = new BitmapImage();
image.BeginInit();
image.UriSource = new Uri(fileName);
image.EndInit();
ImageBehavior.SetAnimatedSource(img, image);
ImageBehavior.SetRepeatBehavior(img, new RepeatBehavior(0));
ImageBehavior.SetRepeatBehavior(img, RepeatBehavior.Forever);

var files = Directory.GetFiles(@"E:\ftproot\sales");

Here is another example using the lapply and table functions in base R.

freqList = lapply(select_if(tips, is.factor), 
              function(x) {
                  df = data.frame(table(x))

                  df = data.frame(fct = df[, 1], 
                                  n = sapply(df[, 2], function(y) {
                                      round(y / nrow(dat), 2)
                                    }
                                )
                            )
                  return(df) 
                    }
                )

Use print(freqList) to see the proportion tables (percent of frequencies) for each column/feature/variable (depending on your tradecraft) that is labeled as a factor.

The other option for using PHP scripts sans extension is

Options +MultiViews

Or even just following in the directories .htaccess:

DefaultType application/x-httpd-php

The latter allows having all filenames without extension script being treated as PHP scripts. While MultiViews makes the webserver look for alternatives, when just the basename is provided (there's a performance hit with that however).

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

You can use it by easy way, through store method in your controller

like the below

First, we must create a form with file input to let us upload our file.

{{Form::open(['route' => 'user.store', 'files' => true])}}

{{Form::label('user_photo', 'User Photo',['class' => 'control-label'])}}
{{Form::file('user_photo')}}
{{Form::submit('Save', ['class' => 'btn btn-success'])}}

{{Form::close()}}

Here is how we can handle file in our controller.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class UserController extends Controller
{

  public function store(Request $request)
  {

  // get current time and append the upload file extension to it,
  // then put that name to $photoName variable.
  $photoName = time().'.'.$request->user_photo->getClientOriginalExtension();

  /*
  talk the select file and move it public directory and make avatars
  folder if doesn't exsit then give it that unique name.
  */
  $request->user_photo->move(public_path('avatars'), $photoName);

  }
}

That’s it. Now you can save the $photoName to the database as a user_photo field value. You can use asset(‘avatars’) function in your view and access the photos.

From the ansible docs: If a required variable has not been set, you can skip or fail using Jinja2’s defined test. For example:

tasks:

- shell: echo "I've got '{{ foo }}' and am not afraid to use it!"
  when: foo is defined

- fail: msg="Bailing out. this play requires 'bar'"
  when: bar is not defined

So in your case, when: deployed_revision is not defined should work

There are mutiple applications for Java's annotations. First of all, they may used by the compiler (or compiler extensions). Consider for example the Override annotation:

class Foo {

    @Override public boolean equals(Object other) {
        return ...;
    }
}

This one is actually built into the Java JDK. The compiler will signal an error, if some method is tagged with it, which does not override a method inherited from a base class. This annotation may be helpful in order to avoid the common mistake, where you actually intend to override a method, but fail to do so, because the signature given in your method does not match the signature of the method being overridden:

class Foo {

    @Override public boolean equals(Foo other) {  // Compiler signals an error for this one
        return ...;
    }
}

As of JDK7, annotations are allowed on any type. This feature can now be used for compiler annotations such as NotNull, like in:

public void processSomething(@NotNull String text) {
    ...
}

which allows the compiler to warn you about improper/unchecked uses of variables and null values.

Another more advanced application for annotations involves reflection and annotation processing at run-time. This is (I think) what you had in mind when you speak of annotations as "replacement for XML based configuration". This is the kind of annotation processing used, for example, by various frameworks and JCP standards (persistence, dependency injection, you name it) in order to provide the necessary meta-data and configuration information.

This type of behaviour is typically solved (in OOP languages) using polymorphism. Each type of bullet would be responsible for knowing how it travels. For instance:

class Bullet(object):
    def __init__(self):
        self.curve = None
        self.speed = None
        self.acceleration = None
        self.sprite_image = None

class RegularBullet(Bullet):
    def __init__(self):
        super(RegularBullet, self).__init__()
        self.speed = 10

class Grenade(Bullet):
    def __init__(self):
        super(Grenade, self).__init__()
        self.speed = 4
        self.curve = 3.5

add_bullet(Grendade())

def add_bullet(bullet):
    c_function(bullet.speed, bullet.curve, bullet.acceleration, bullet.sprite, bullet.x, bullet.y)


void c_function(double speed, double curve, double accel, char[] sprite, ...) {
    if (speed != null && ...) regular_bullet(...)
    else if (...) curved_bullet(...)
    //..etc..
}

Pass as many arguments to the c_function that exist, and then do the job of determining which c function to call based on the values in the initial c function. So, Python should only ever be calling the one c function. That one c function looks at the arguments, and then can delegate to other c functions appropriately.

You're essentially just using each subclass as a different data container, but by defining all the potential arguments on the base class, the subclasses are free to ignore the ones they do nothing with.

When a new type of bullet comes along, you can simply define one more property on the base, change the one python function so that it passes the extra property, and the one c_function that examines the arguments and delegates appropriately. It doesn't sound too bad I guess.

That is the mode with which you are opening the file. "wb" means that you are writing to the file (w), and that you are writing in binary mode (b).

Check out the documentation for more: clicky

You can use list comprehension:

res_list = [i[0] for i in rows]

This should make the trick

create procedure <procedure_name>(p_cur out sys_refcursor) as begin open p_cur for select * from <table_name> end;

Please use Like below.
<a style="cursor: pointer" **(click)="yourFunctionComponent()"** >
<i class="fa fa-dribbble fa-4x"></i>
 </a>

The above can be used so that the fa icon will be shown and also on the click function you could write your logic.

I know this is quite an old one, but I faced similar issue and resolved it in a different way. The actuator-autoconfigure pom somehow was invalid and so it was throwing IllegalStateException. I removed the actuator* dependencies from my maven repo and did a Maven update in eclipse, which then downloaded the correct/valid dependencies and resolved my issue.

Actually, I think this is the best way.

from django.core.validators import URLValidator
from django.core.exceptions import ValidationError

val = URLValidator(verify_exists=False)
try:
    val('http://www.google.com')
except ValidationError, e:
    print e

If you set verify_exists to True, it will actually verify that the URL exists, otherwise it will just check if it's formed correctly.

edit: ah yeah, this question is a duplicate of this: How can I check if a URL exists with Django’s validators?

Do it like this. This approach lets you search a file of any size (big size won't crash the script) and will return ALL lines that match the string you want.

<?php
$searchthis = "mystring";
$matches = array();

$handle = @fopen("path/to/inputfile.txt", "r");
if ($handle)
{
    while (!feof($handle))
    {
        $buffer = fgets($handle);
        if(strpos($buffer, $searchthis) !== FALSE)
            $matches[] = $buffer;
    }
    fclose($handle);
}

//show results:
print_r($matches);
?>

Note the way strpos is used with !== operator.

All answers so far use find, so here's one with just the shell. No need for external tools in your case:

for dir in /tmp/*/     # list directories in the form "/tmp/dirname/"
do
    dir=${dir%*/}      # remove the trailing "/"
    echo "${dir##*/}"    # print everything after the final "/"
done

Add

@Produces({"image/jpeg,image/png"})

to

@POST
@Path("/pdf")
@Consumes({ MediaType.MULTIPART_FORM_DATA })
@Produces({"image/jpeg,image/png"})
//@Produces("text/plain")
public Response uploadPdfFile(@FormDataParam("file") InputStream fileInputStream,@FormDataParam("file") FormDataContentDisposition fileMetaData) throws Exception {
    ...
}

Set it in the body selector of your css. E.g.

body {
    font: 16px Arial, sans-serif;
}

I am one of the authors, so the answer can be biased. It is open-source (Apache 2.0), but the plugin is not free. You don't have to pay (obviously) if you clone and build it locally.

On Intellij IDEA, ZenUML can generate sequence diagram from Java code.

Check it out at https://plugins.jetbrains.com/plugin/12437-zenuml-support

You can use Context.checkCallingorSelfPermission() function for this. Here is an example:

private boolean checkWriteExternalPermission()
{
    String permission = android.Manifest.permission.WRITE_EXTERNAL_STORAGE;
    int res = getContext().checkCallingOrSelfPermission(permission);
    return (res == PackageManager.PERMISSION_GRANTED);            
}

You could potentially use goto, but I would prefer to set a flag that stops the loop. Then break out of the switch.

I always use something similar to this:

Uses
   StrUtils, Classes;

Var
  Str, Delimiter : String;
begin
  // Str is the input string, Delimiter is the delimiter
  With TStringList.Create Do
  try
    Text := ReplaceText(S,Delim,#13#10);

    // From here on and until "finally", your desired result strings are
    // in strings[0].. strings[Count-1)

  finally
    Free; //Clean everything up, and liberate your memory ;-)
  end;

end;

From this post:

To get the entire PC CPU and Memory usage:

using System.Diagnostics;

Then declare globally:

private PerformanceCounter theCPUCounter = 
   new PerformanceCounter("Processor", "% Processor Time", "_Total"); 

Then to get the CPU time, simply call the NextValue() method:

this.theCPUCounter.NextValue();

This will get you the CPU usage

As for memory usage, same thing applies I believe:

private PerformanceCounter theMemCounter = 
   new PerformanceCounter("Memory", "Available MBytes");

Then to get the memory usage, simply call the NextValue() method:

this.theMemCounter.NextValue();

For a specific process CPU and Memory usage:

private PerformanceCounter theCPUCounter = 
   new PerformanceCounter("Process", "% Processor Time",              
   Process.GetCurrentProcess().ProcessName);

where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

private PerformanceCounter theMemCounter = 
   new PerformanceCounter("Process", "Working Set",
   Process.GetCurrentProcess().ProcessName);

where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

Note that Working Set may not be sufficient in its own right to determine the process' memory footprint -- see What is private bytes, virtual bytes, working set?

To retrieve all Categories, see Walkthrough: Retrieving Categories and Counters

The difference between Processor\% Processor Time and Process\% Processor Time is Processor is from the PC itself and Process is per individual process. So the processor time of the processor would be usage on the PC. Processor time of a process would be the specified processes usage. For full description of category names: Performance Monitor Counters

An alternative to using the Performance Counter

Use System.Diagnostics.Process.TotalProcessorTime and System.Diagnostics.ProcessThread.TotalProcessorTime properties to calculate your processor usage as this article describes.

join is not a jQuery function .Its a javascript function.

The join() method joins the elements of an array into a string, and returns the string.The elements will be separated by a specified separator. The default separator is comma (,).

For all the Kotlin users out there:

context?.let {

Here is one common problem I haven't seen addressed in the other comments: is your host running a cache of some sort? If they are automatically caching results in some fashion you would get this sort of behavior.

If you are on windows and you encountered the same problem, try to kill the adb.exe process from task manager and then try to run your app again.

You have to create a variable of the type of the class, and set it equal to a new instance of the object first.

GradeBook myGradeBook = new GradeBook();

Then call the method on the obect you just created.

myGradeBook.[method you want called]

To specify any additional asset folder I've used this with my Gradle. This adds moreAssets, a folder in the project root, to the assets.

android {
    sourceSets {
        main.assets.srcDirs += '../moreAssets'
    }
}

The return statement you have is stuck in the inner function, so it won't return from the outer function. You just need a little more code:

function getMachine(color, qty) {
    var returnValue = null;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            returnValue = thisArray[3];
            return false; // this breaks out of the each
        }
    });
    return returnValue;
}

var retval = getMachine(color, qty);

Example:

driver.execute_script("arguments[0].scrollIntoView();", driver.find_element_by_css_selector(.your_css_selector))

This one always works for me for any type of selectors. There is also the Actions class, but for this case, it is not so reliable.

No, it's not possible in java.

You can do this way .. But try to avoid it.

String one, two, three;
one = two = three = "";

You can return Observable.of(empty_variable), for example

Observable.of('');

// or
Observable.of({});

// etc

You cannot do this on multiple fields. You can also look for this.

Try running you asyntask from the UI thread. I faced this issue when I wasn't doing the same!

You can connect to psql as below and write your sql queries like you do in a regular postgres function within the block. There, bash variables can be used. However, the script should be strictly sql, even for comments you need to use -- instead of #:

#!/bin/bash
psql postgresql://<user>:<password>@<host>/<db> << EOF
       <your sql queries go here>
EOF

With a <script> right after the <style> that applies the !important things, you should be able to do something like this:

var lastStylesheet = document.styleSheets[document.styleSheets.length - 1];
lastStylesheet.disabled = true;

document.write('<style type="text/css">');
// Call fixBackground for each element that needs fixing
document.write('</style>');

lastStylesheet.disabled = false;

function fixBackground(el) {
    document.write('html #' + el.id + ' { background-image: ' +
        document.defaultView.getComputedStyle(el).backgroundImage +
        ' !important; }');
}

This probably depends on what kind of browser compatibility you need, though.

Based on Wikipedia's articles.

Greedy Approach

A greedy algorithm is an algorithm that follows the problem solving heuristic of making the locally optimal choice at each stage with the hope of finding a global optimum. In many problems, a greedy strategy does not in general produce an optimal solution, but nonetheless a greedy heuristic may yield locally optimal solutions that approximate a global optimal solution in a reasonable time.

We can make whatever choice seems best at the moment and then solve the subproblems that arise later. The choice made by a greedy algorithm may depend on choices made so far but not on future choices or all the solutions to the subproblem. It iteratively makes one greedy choice after another, reducing each given problem into a smaller one.

Dynamic programming

The idea behind dynamic programming is quite simple. In general, to solve a given problem, we need to solve different parts of the problem (subproblems), then combine the solutions of the subproblems to reach an overall solution. Often when using a more naive method, many of the subproblems are generated and solved many times. The dynamic programming approach seeks to solve each subproblem only once, thus reducing the number of computations: once the solution to a given subproblem has been computed, it is stored or "memo-ized": the next time the same solution is needed, it is simply looked up. This approach is especially useful when the number of repeating subproblems grows exponentially as a function of the size of the input.

Difference

Greedy choice property

We can make whatever choice seems best at the moment and then solve the subproblems that arise later. The choice made by a greedy algorithm may depend on choices made so far but not on future choices or all the solutions to the subproblem. It iteratively makes one greedy choice after another, reducing each given problem into a smaller one. In other words, a greedy algorithm never reconsiders its choices.

This is the main difference from dynamic programming, which is exhaustive and is guaranteed to find the solution. After every stage, dynamic programming makes decisions based on all the decisions made in the previous stage, and may reconsider the previous stage's algorithmic path to solution.

For example, let's say that you have to get from point A to point B as fast as possible, in a given city, during rush hour. A dynamic programming algorithm will look into the entire traffic report, looking into all possible combinations of roads you might take, and will only then tell you which way is the fastest. Of course, you might have to wait for a while until the algorithm finishes, and only then can you start driving. The path you will take will be the fastest one (assuming that nothing changed in the external environment).

On the other hand, a greedy algorithm will start you driving immediately and will pick the road that looks the fastest at every intersection. As you can imagine, this strategy might not lead to the fastest arrival time, since you might take some "easy" streets and then find yourself hopelessly stuck in a traffic jam.

Some other details...

In mathematical optimization, greedy algorithms solve combinatorial problems having the properties of matroids.

Dynamic programming is applicable to problems exhibiting the properties of overlapping subproblems and optimal substructure.

I had a similar problem with pip and easy_install:

Cannot fetch index base URL https://pypi.python.org/simple/

As suggested in the referenced blog post, there must be an issue with some older versions of OpenSSL being incompatible with pip 1.3.1.

Installing pip-1.2.1 is a working workaround.

This definitely happens in RHEL/CentOS 4 distros

Just in case for data.table users, the following works for me:

df[, grep("ABC", names(df)), with = FALSE]

The ObjectDumper class has been known to do that. I've never confirmed, but I've always suspected that the immediate window uses that.

EDIT: I just realized, that the code for ObjectDumper is actually on your machine. Go to:

C:/Program Files/Microsoft Visual Studio 9.0/Samples/1033/CSharpSamples.zip

This will unzip to a folder called LinqSamples. In there, there's a project called ObjectDumper. Use that.

The short answer as to why I use an IDE is laziness.

I'm a lazy soul who doesn't like to do things a difficult way when there is an easy way to do it instead. IDE's make life easy and so appeal to us lazy folk.

As I type code, the IDE automatically checks the validity of the code, I can highlight a method and hit F1 to get help, right click and select "go to to definition" to jump straight to where it is defined. I hit one button and the application, with debugger automatically attached is launched for me. And so the list goes on. All the things that a developer does on a day to day basis is gathered under one roof.

There is no need to use an IDE. It is just much harder work not to.

One thing that has caught me out in the past is that if you have the services viewer running then that prevents the services from being fully deleted, so close that beforehand

The way you declare the date property as an input looks incorrect but its hard to say if it's the only problem without seeing all your code. Rather than using @Input('date') declare the date property like so: private _date: string;. Also, make sure you are instantiating the model with the new keyword. Lastly, access the property using regular dot notation.

Check your work against this example from https://www.typescriptlang.org/docs/handbook/classes.html :

let passcode = "secret passcode";

class Employee {
    private _fullName: string;

    get fullName(): string {
        return this._fullName;
    }

    set fullName(newName: string) {
        if (passcode && passcode == "secret passcode") {
            this._fullName = newName;
        }
        else {
            console.log("Error: Unauthorized update of employee!");
        }
    }
}

let employee = new Employee();
employee.fullName = "Bob Smith";
if (employee.fullName) {
    console.log(employee.fullName);
}

I recommend you to use the open-source package guzzle that is fully unit tested and uses the latest coding practices.

Installing Guzzle

Go to the command line in your project folder and type in the following command (assuming you already have the package manager composer installed). If you need help how to install Composer, you should have a look here.

php composer.phar require guzzlehttp/guzzle

Using Guzzle to send a POST request

The usage of Guzzle is very straight forward as it uses a light-weight object-oriented API:

// Initialize Guzzle client
$client = new GuzzleHttp\Client();

// Create a POST request
$response = $client->request(
    'POST',
    'http://example.org/',
    [
        'form_params' => [
            'key1' => 'value1',
            'key2' => 'value2'
        ]
    ]
);

// Parse the response object, e.g. read the headers, body, etc.
$headers = $response->getHeaders();
$body = $response->getBody();

// Output headers and body for debugging purposes
var_dump($headers, $body);

Now I return Object. I don't know better solution, but it works.

@RequestMapping(value="", method=RequestMethod.GET, produces=MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody ResponseEntity<Object> getAll() {
    List<Entity> entityList = entityManager.findAll();

    List<JSONObject> entities = new ArrayList<JSONObject>();
    for (Entity n : entityList) {
        JSONObject Entity = new JSONObject();
        entity.put("id", n.getId());
        entity.put("address", n.getAddress());
        entities.add(entity);
    }
    return new ResponseEntity<Object>(entities, HttpStatus.OK);
}

Use the extraData property on your FlatList component.

As the documentation states:

By passing extraData={this.state} to FlatList we make sure FlatList will re-render itself when the state.selected changes. Without setting this prop, FlatList would not know it needs to re-render any items because it is also a PureComponent and the prop comparison will not show any changes.

the easiest way to do that in angular or angularjs without external modules or directives is using list and datalist HTML5. You just get a json and use ng-repeat for feeding the options in datalist. The json you can fetch it from ajax.

in this example:

• ctrl.query is the query that you enter when you type.
• ctrl.msg is the message that is showing in the placeholder
• ctrl.dataList is the json fetched

then you can add filters and orderby in the ng-reapet

!! list and datalist id must have the same name !!

 <input type="text" list="autocompleList" ng-model="ctrl.query" placeholder={{ctrl.msg}}>
<datalist id="autocompleList">
        <option ng-repeat="Ids in ctrl.dataList value={{Ids}}  >
</datalist>

UPDATE : is native HTML5 but be carreful with the type browser and version. check it out : https://caniuse.com/#search=datalist.

The CURL extension ext/curl is not installed or enabled in your PHP installation. Check the manual for information on how to install or enable CURL on your system.

So,

You have plenty of options to check whether your variable is string or not:

a = "my string"
type(a) == str # first 
a.__class__ == str # second
isinstance(a, str) # third
str(a) == a # forth
type(a) == type('') # fifth

This order is for purpose.

The result of a subtraction generating a negative number in an unsigned type is well-defined:

1. [...] A computation involving unsigned operands can never overflow, because a result that cannot be represented by the resulting unsigned integer type is reduced modulo the number that is one greater than the largest value that can be represented by the resulting type. (ISO/IEC 9899:1999 (E) §6.2.5/9)

As you can see, (unsigned)0 - (unsigned)1 equals -1 modulo UINT_MAX+1, or in other words, UINT_MAX.

Note that although it does say "A computation involving unsigned operands can never overflow", which might lead you to believe that it applies only for exceeding the upper limit, this is presented as a motivation for the actual binding part of the sentence: "a result that cannot be represented by the resulting unsigned integer type is reduced modulo the number that is one greater than the largest value that can be represented by the resulting type." This phrase is not restricted to overflow of the upper bound of the type, and applies equally to values too low to be represented.

I have the same problem since yesterday. Yesterday, I fixed it by creating a new workspace and reimporting the projects. It seemed to work well, but today it started again.

So, today I created the folder and the file manually and gave the full permissions -rwxrwxrwx.

Seems to work again...

You're getting the error because result defined as Sequential() is just a container for the model and you have not defined an input for it.

Given what you're trying to build set result to take the third input x3.

first = Sequential()
first.add(Dense(1, input_shape=(2,), activation='sigmoid'))

second = Sequential()
second.add(Dense(1, input_shape=(1,), activation='sigmoid'))

third = Sequential()
# of course you must provide the input to result which will be your x3
third.add(Dense(1, input_shape=(1,), activation='sigmoid'))

# lets say you add a few more layers to first and second.
# concatenate them
merged = Concatenate([first, second])

# then concatenate the two outputs

result = Concatenate([merged,  third])

ada_grad = Adagrad(lr=0.1, epsilon=1e-08, decay=0.0)

result.compile(optimizer=ada_grad, loss='binary_crossentropy',
               metrics=['accuracy'])

However, my preferred way of building a model that has this type of input structure would be to use the functional api.

Here is an implementation of your requirements to get you started:

from keras.models import Model
from keras.layers import Concatenate, Dense, LSTM, Input, concatenate
from keras.optimizers import Adagrad

first_input = Input(shape=(2, ))
first_dense = Dense(1, )(first_input)

second_input = Input(shape=(2, ))
second_dense = Dense(1, )(second_input)

merge_one = concatenate([first_dense, second_dense])

third_input = Input(shape=(1, ))
merge_two = concatenate([merge_one, third_input])

model = Model(inputs=[first_input, second_input, third_input], outputs=merge_two)
ada_grad = Adagrad(lr=0.1, epsilon=1e-08, decay=0.0)
model.compile(optimizer=ada_grad, loss='binary_crossentropy',
               metrics=['accuracy'])

To answer the question in the comments:

1. How are result and merged connected? Assuming you mean how are they concatenated.

Concatenation works like this:

  a        b         c
a b c   g h i    a b c g h i
d e f   j k l    d e f j k l

i.e rows are just joined.

2. Now, x1 is input to first, x2 is input into second and x3 input into third.

while(choice!=99)
{
  cin>>choice;
  if (choice==99)
    exit(0);
  cin>>gNum;
}

Trust me, that will exit the loop. If that doesn't work nothing will. Mind, this may not be what you want...

Call SOAP webservice in c#

using (var client = new UpdatedOutlookServiceReferenceAPI.OutlookServiceSoapClient("OutlookServiceSoap"))
{
    ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12;
    var result = client.UploadAttachmentBase64(GUID, FinalFileName, fileURL);

    if (result == true)
    {
        resultFlag = true;
    }
    else
    {
        resultFlag = false;
    }
    LogWriter.LogWrite1("resultFlag : " + resultFlag);
}

One has exactly space for 11 bytes, the other for exactly 11 characters. Some charsets such as Unicode variants may use more than one byte per char, therefore the 11 byte field might have space for less than 11 chars depending on the encoding.

There is a php library (pdfparser) that does exactly what you want.

project website

http://www.pdfparser.org/

github

https://github.com/smalot/pdfparser

Demo page/api

http://www.pdfparser.org/demo

After including pdfparser in your project you can get all text from mypdf.pdf like so:

<?php
$parser = new \installpath\PdfParser\Parser();
$pdf    = $parser->parseFile('mypdf.pdf');  
$text = $pdf->getText();
echo $text;//all text from mypdf.pdf

?>

Simular you can get the metadata from the pdf as wel as getting the pdf objects (for example images).

file.length() will return you the length in bytes, then you divide that by 1048576, and now you've got megabytes!

You don't need to use display:inline to achieve this:

.inline { 
    border: 1px solid red;
    margin:10px;
    float:left;/*Add float left*/
    margin :10px;
}

You can use float-left.

Using float:left is best way to place multiple div elements in one line. Why? Because inline-block does have some problem when is viewed in IE older versions.

template<typename T>
string str(T begin, T end)

    stringstream ss;
    bool first = true;
    for (; begin != end; begin++)

            ss << ", ";
        ss << *begin;
        first = false;
    }
    return ss.str();
}

This is the str function that can make integers turn into a string and not into a char for what the integer represents. Also works for doubles.

If you can't use rgba due to browser support, and you don't want to include a semi-transparent white PNG, you will have to create two positioned elements. One for the white box, with opacity, and one for the overlaid text, solid.

Some IDEs highlight the code in heredoc strings automatically - which makes using heredoc for XML or HTML visually appealing.

I personally like it for longer parts of i.e. XML since I don't have to care about quoting quote characters and can simply paste the XML.

I'm very thoroughly investigating the matter of accuracy/rssi/proximity with iBeacons and I really really think that all the resources in the Internet (blogs, posts in StackOverflow) get it wrong.

davidgyoung (accepted answer, > 100 upvotes) says:

Note that the term "accuracy" here is iOS speak for distance in meters.

Actually, most people say this but I have no idea why! Documentation makes it very very clear that CLBeacon.proximity:

Indicates the one sigma horizontal accuracy in meters. Use this property to differentiate between beacons with the same proximity value. Do not use it to identify a precise location for the beacon. Accuracy values may fluctuate due to RF interference.

Let me repeat: one sigma accuracy in meters. All 10 top pages in google on the subject has term "one sigma" only in quotation from docs, but none of them analyses the term, which is core to understand this.

Very important is to explain what is actually one sigma accuracy. Following URLs to start with: http://en.wikipedia.org/wiki/Standard_error, http://en.wikipedia.org/wiki/Uncertainty

In physical world, when you make some measurement, you always get different results (because of noise, distortion, etc) and very often results form Gaussian distribution. There are two main parameters describing Gaussian curve:

1. mean (which is easy to understand, it's value for which peak of the curve occurs).
2. standard deviation, which says how wide or narrow the curve is. The narrower curve, the better accuracy, because all results are close to each other. If curve is wide and not steep, then it means that measurements of the same phenomenon differ very much from each other, so measurement has a bad quality.

one sigma is another way to describe how narrow/wide is gaussian curve.
It simply says that if mean of measurement is X, and one sigma is s, then 68% of all measurements will be between X - s and X + s.

Example. We measure distance and get a gaussian distribution as a result. The mean is 10m. If s is 4m, then it means that 68% of measurements were between 6m and 14m.

When we measure distance with beacons, we get RSSI and 1-meter calibration value, which allow us to measure distance in meters. But every measurement gives different values, which form gaussian curve. And one sigma (and accuracy) is accuracy of the measurement, not distance!

It may be misleading, because when we move beacon further away, one sigma actually increases because signal is worse. But with different beacon power-levels we can get totally different accuracy values without actually changing distance. The higher power, the less error.

There is a blog post which thoroughly analyses the matter: http://blog.shinetech.com/2014/02/17/the-beacon-experiments-low-energy-bluetooth-devices-in-action/

Author has a hypothesis that accuracy is actually distance. He claims that beacons from Kontakt.io are faulty beacuse when he increased power to the max value, accuracy value was very small for 1, 5 and even 15 meters. Before increasing power, accuracy was quite close to the distance values. I personally think that it's correct, because the higher power level, the less impact of interference. And it's strange why Estimote beacons don't behave this way.

I'm not saying I'm 100% right, but apart from being iOS developer I have degree in wireless electronics and I think that we shouldn't ignore "one sigma" term from docs and I would like to start discussion about it.

It may be possible that Apple's algorithm for accuracy just collects recent measurements and analyses the gaussian distribution of them. And that's how it sets accuracy. I wouldn't exclude possibility that they use info form accelerometer to detect whether user is moving (and how fast) in order to reset the previous distribution distance values because they have certainly changed.

The quotes you use are the issue:

You should use the "

Yes it is possible. When writing the stream creating the csv, the first thing to do is this:

myStream.Write(Encoding.UTF8.GetPreamble(), 0, Encoding.UTF8.GetPreamble().Length)

In the <tomcat-home>\conf\catalina.properties file, add this new line:

spring.profiles.active=dev

Taking reference of ThiefMaster? sometimes we get an error with value given as '\n' or null and perform for that required to handle ValueError:

Handling the exception is the way to go

try:
    gotdata = dlist[1]
except (IndexError, ValueError):
    gotdata = 'null'

Use a for loop instead of .forEach()

var myObj = [{"a": "1","b": null},{"a": "2","b": 5}]
var result = false

for(var call of myObj) {
    console.log(call)
    
    var a = call['a'], b = call['b']
     
    if(a == null || b == null) {

I did a small experiment of running a method "1,000,000,000 (one billion)" times with "Parallel.For" and one with "Task" objects.

I measured the processor time and found Parallel more efficient. Parallel.For divides your task in to small work items and executes them on all the cores parallely in a optimal way. While creating lot of task objects ( FYI TPL will use thread pooling internally) will move every execution on each task creating more stress in the box which is evident from the experiment below.

I have also created a small video which explains basic TPL and also demonstrated how Parallel.For utilizes your core more efficiently http://www.youtube.com/watch?v=No7QqSc5cl8 as compared to normal tasks and threads.

Experiment 1

Parallel.For(0, 1000000000, x => Method1());

Experiment 2

for (int i = 0; i < 1000000000; i++)
{
    Task o = new Task(Method1);
    o.Start();
}

It seems to me that the best and easiest way is commented by Dennis G:

And now go to [Settings > Shortcut Mapper > Plugin Commands > Copy all Formats to clipboard] and set it to CTRL+SHIFT+C --> Instant joy. CTRL+C to copy the raw text, CTRL+SHIFT+C to copy with formatting. This should be default.

Hoping help someone just like me!

Like what Amber says in her answer: create a function. In fact when you don't have to make classes if you have something like:

class Person(object):
    def __init__(self, arg1, arg2):
        self.arg1 = arg1
        self.arg2 = arg2

    def compute(self, other):
        """ Example of bad class design, don't care about the result """
        return self.arg1 + self.arg2 % other

Here you just have a function encapsulate in a class. This just make the code less readable and less efficient. In fact the function compute can be written just like this:

def compute(arg1, arg2, other):
     return arg1 + arg2 % other

You should use classes only if you have more than 1 function to it and if keep a internal state (with attributes) has sense. Otherwise, if you want to regroup functions, just create a module in a new .py file.

You might look this video (Youtube, about 30min), which explains my point. Jack Diederich shows why classes are evil in that case and why it's such a bad design, especially in things like API.
It's quite a long video but it's a must see.

You are pretty confused my friend. There are no LOOPS in SQL, only in PL/SQL. Here's a few examples based on existing Oracle table - copy/paste to see results:

-- Numeric FOR loop --
set serveroutput on -->> do not use in TOAD --
DECLARE
  k NUMBER:= 0;
BEGIN
  FOR i IN 1..10 LOOP
    k:= k+1;
    dbms_output.put_line(i||' '||k);
 END LOOP;
END;
/

-- Cursor FOR loop --
set serveroutput on
DECLARE
   CURSOR c1 IS SELECT * FROM scott.emp;
   i NUMBER:= 0;
BEGIN
  FOR e_rec IN c1 LOOP
  i:= i+1;
    dbms_output.put_line(i||chr(9)||e_rec.empno||chr(9)||e_rec.ename);
  END LOOP;
END;
/

-- SQL example to generate 10 rows --
SELECT 1 + LEVEL-1 idx
  FROM dual
CONNECT BY LEVEL <= 10
/

For 19.1 above on Linux,

Close the App or any window of Smartgit

Go to:

/home/[USERNAME]/.config/smartgit/[CURRENT OR LAST VERSION]

open the file:

preferences.yml

Search for:

"listx: {" in this file

You will find something like this:

listx: {ePP: 1607503071922, eUT: -9223377036854775808, nRT: -9223377036854775808, eV: '20.1', uid: emobf7q63s83}

So now all you need is delete the string inside the {} So it will be like this:

listx: {}

Now save the file and start Smartgit. You will have all repositories and other preferences and you will be asked for set the type of license.

You have all those 'junk variables' outside of your mainline while True loop. To make the code easier to read those variables can be brought inside the loop, right next to where they are used. You can also set up a variable naming convention for these program control switches. So for example:

#                                  # _already_done checkpoint logic
    try:
        ran_this_user_request_already_done
    except:
        this_user_request()
        ran_this_user_request_already_done = 1

Note that on the first execution of this code the variable ran_this_user_request_already_done is not defined until after this_user_request() is called.

a simple moving average for 10 items, using a list:

#include <list>

std::list<float> listDeltaMA;

float getDeltaMovingAverage(float delta)
{
    listDeltaMA.push_back(delta);
    if (listDeltaMA.size() > 10) listDeltaMA.pop_front();
    float sum = 0;
    for (std::list<float>::iterator p = listDeltaMA.begin(); p != listDeltaMA.end(); ++p)
        sum += (float)*p;
    return sum / listDeltaMA.size();
}

From man githooks:

pre-commit
This hook is invoked by git commit, and can be bypassed with --no-verify option. It takes no parameter, and is invoked before obtaining the proposed commit log message and making a commit. Exiting with non-zero status from this script causes the git commit to abort.

What you are looking for is 'type casting'. typecasting (putting the type you know you want in brackets) tells the compiler you know what you are doing and are cool with it. The old way that is inherited from C is as follows.

float var_a = 9.99;
int   var_b = (int)var_a;

If you had only tried to write

int var_b = var_a;

You would have got a warning that you can't implicitly (automatically) convert a float to an int, as you lose the decimal.

This is referred to as the old way as C++ offers a superior alternative, 'static cast'; this provides a much safer way of converting from one type to another. The equivalent method would be (and the way you should do it)

float var_x = 9.99;
int   var_y = static_cast<int>(var_x);

This method may look a bit more long winded, but it provides much better handling for situations such as accidentally requesting a 'static cast' on a type that cannot be converted. For more information on the why you should be using static cast, see this question.

The default parser can parse your input. So you don't need a custom formatter and

String dateTime = "2012-02-22T02:06:58.147Z";
ZonedDateTime d = ZonedDateTime.parse(dateTime);

works as expected.
