In addition, If you have sections for tableview, you should not try to find every rows you want to refresh, you should use reload sections. It is easy and more balanced process:

yourTableView.reloadSections(IndexSet, with: UITableViewRowAnimation)

Obligatory answer in Swift : NSIndexPath(forRow:row, inSection: section)

You will notice that NSIndexPath.indexPathForRow(row, inSection: section) is not available in swift and you must use the first method to construct the indexPath.

You can use the following code to get last cell.

UITableViewCell *cell = [tableView cellForRowAtIndexPath:lastIndexPath];

I know the OP says Recycle Bin. What I do though is recreate the file, especially if it's a single file. And when in the file, I just press CMD+Z (I'm on a Mac) and I get my file back.

1. Recreate the file in the same directory from where it was deleted.
2. CMD+Z inside of the newly created file.

I had a doubt that whether the encrypted text will be same for single text when encryption done by multiple times on a same text??

This depends strongly on the crypto algorithm you use:

• One goal of some/most (mature) algorithms is that the encrypted text is different when encryption done twice. One reason to do this is, that an attacker how known the plain and the encrypted text is not able to calculate the key.
• Other algorithm (mainly one way crypto hashes) like MD5 or SHA based on the fact, that the hashed text is the same for each encryption/hash.

As "@sarnold", aptly pointed out, any process can send signal to any other process, hence, one process can send SIGABORT to other process & in that case the receiving process is unable to distinguish whether its coming because of its own tweaking of memory etc, or someone else has "unicastly", send to it.

In one of the systems I worked there is one deadlock detector which actually detects if process is coming out of some task by giving heart beat or not. If not, then it declares the process is in deadlock state and sends SIGABORT to it.

I just wanted to share this prospective with reference to question asked.

I think the Java Service Wrapper works well. Note that there are three ways to integrate your application. It sounds like option 1 will work best for you given that you don't want to change the code. The configuration file can get a little crazy, but just remember that (for option 1) the program you're starting and for which you'll be specifying arguments, is their helper program, which will then start your program. They have an example configuration file for this.

Try this:

$objPHPExcel->getActiveSheet()->getRowDimension('1')->setRowHeight(40);

The best thing to do is to install the Tampermonkey extension.

This will allow you to easily install Greasemonkey scripts, and to easily manage them. Also it makes it easier to install userscripts directly from sites like OpenUserJS, MonkeyGuts, etc.

Finally, it unlocks most all of the GM functionality that you don't get by installing a GM script directly with Chrome. That is, more of what GM on Firefox can do, is available with Tampermonkey.

But, if you really want to install a GM script directly, it's easy a right pain on Chrome these days...

Chrome After about August, 2014:

You can still drag a file to the extensions page and it will work... Until you restart Chrome. Then it will be permanently disabled. See Continuing to "protect" Chrome users from malicious extensions for more information. Again, Tampermonkey is the smart way to go. (Or switch browsers altogether to Opera or Firefox.)

Chrome 21+ :

Chrome is changing the way extensions are installed. Userscripts are pared-down extensions on Chrome but. Starting in Chrome 21, link-click behavior is disabled for userscripts. To install a user script, drag the **.user.js* file into the Extensions page (chrome://extensions in the address input).

Older Chrome versions:

Merely drag your **.user.js* files into any Chrome window. Or click on any Greasemonkey script-link.

You'll get an installation warning:

Click Continue.

You'll get a confirmation dialog:

Click Add.

Notes:

1. Scripts installed this way have limitations compared to a Greasemonkey (Firefox) script or a Tampermonkey script. See Cross-browser user-scripting, Chrome section.

Controlling the Script and name:

By default, Chrome installs scripts in the Extensions folder¹, full of cryptic names and version numbers. And, if you try to manually add a script under this folder tree, it will be wiped the next time Chrome restarts.

To control the directories and filenames to something more meaningful, you can:

1. Create a directory that's convenient to you, and not where Chrome normally looks for extensions. For example, Create: C:\MyChromeScripts\.

2. For each script create its own subdirectory. For example, HelloWorld.

3. In that subdirectory, create or copy the script file. For example, Save this question's code as: HelloWorld.user.js.

4. You must also create a manifest file in that subdirectory, it must be named: manifest.json.

   For our example, it should contain:

   {
       "manifest_version": 2,
       "content_scripts": [ {
           "exclude_globs":    [  ],
           "include_globs":    [ "*" ],
           "js":               [ "HelloWorld.user.js" ],
           "matches":          [   "https://stackoverflow.com/*",
                                   "https://stackoverflow.com/*"
                               ],
           "run_at": "document_end"
       } ],
       "converted_from_user_script": true,
       "description":  "My first sensibly named script!",
       "name":         "Hello World",
       "version":      "1"
   }
   

   The manifest.json file is automatically generated from the meta-block by Chrome, when an user script is installed. The values of @include and @exclude meta-rules are stored in include_globs and exclude_globs, @match (recommended) is stored in the matches list. "converted_from_user_script": true is required if you want to use any of the supported GM_* methods.

5. Now, in Chrome's Extension manager (URL = chrome://extensions/), Expand "Developer mode".

6. Click the Load unpacked extension... button.

7. For the folder, paste in the folder for your script, In this example it is: C:\MyChromeScripts\HelloWorld.

8. Your script is now installed, and operational!

9. If you make any changes to the script source, hit the Reload link for them to take effect:

   

¹ The folder defaults to:

Windows XP:
  Chrome  : %AppData%\..\Local Settings\Application Data\Google\Chrome\User Data\Default\Extensions\
  Chromium: %AppData%\..\Local Settings\Application Data\Chromium\User Data\Default\Extensions\

Windows Vista/7/8:
  Chrome  : %LocalAppData%\Google\Chrome\User Data\Default\Extensions\
  Chromium: %LocalAppData%\Chromium\User Data\Default\Extensions\

Linux:
  Chrome  : ~/.config/google-chrome/Default/Extensions/
  Chromium: ~/.config/chromium/Default/Extensions/

Mac OS X:
  Chrome  : ~/Library/Application Support/Google/Chrome/Default/Extensions/
  Chromium: ~/Library/Application Support/Chromium/Default/Extensions/

Although you can change it by running Chrome with the --user-data-dir= option.

Unique key allows max 2 NULL values. Explaination:

create table teppp
(
id int identity(1,1) primary key,
name varchar(10 )unique,
addresss varchar(10)
)

insert into teppp ( name,addresss) values ('','address1')
insert into teppp ( name,addresss) values ('NULL','address2')
insert into teppp ( addresss) values ('address3')

select * from teppp
null string , address1
NULL,address2
NULL,address3

If you try inserting same values as below:

insert into teppp ( name,addresss) values ('','address4')
insert into teppp ( name,addresss) values ('NULL','address5')
insert into teppp ( addresss) values ('address6')

Every time you will get error like:

Violation of UNIQUE KEY constraint 'UQ__teppp__72E12F1B2E1BDC42'. Cannot insert duplicate key in object 'dbo.teppp'.
The statement has been terminated.

Maybe bind() would help:

button.bind('click', function() {
  alert('User clicked');
});

Use the random module: http://docs.python.org/library/random.html

import random
random.sample(set([1, 2, 3, 4, 5, 6]), 2)

This samples the two values without replacement (so the two values are different).

You need a gutter between two div gutter can be made as following

margin(gutter) = width - gutter size E.g margin = calc(70% - 2em)

<body bgcolor="gray">
<section id="main">
        <div id="left">
            Something here     
        </div>
        <div id="right">
                Someone there
        </div>
</section>
</body>
<style>
body{
    font-size: 10px;
}

#main div{
    float: left;
    background-color:#ffffff;
    width: calc(50% - 1.5em);
    margin-left: 1.5em;
}
</style>

Slight update to cumul's solution.

The function upperFirstAll doesn't work properly if there is more than one space between words. Replace the regular expression for this one to solve it:

$(this).val(txt.toLowerCase().replace(/^(.)|(\s|\-)+(.)/g,

Modern browsers now throw a security error for otherwise well-formed self-signed certificates if they are missing a SAN (Subject Alternate Name). OpenSSL does not provide a command-line way to specify this, so many developers' tutorials and bookmarks are suddenly outdated.

The quickest way to get running again is a short, stand-alone conf file:

1. Create an OpenSSL config file (example: req.cnf)

   [req]
   distinguished_name = req_distinguished_name
   x509_extensions = v3_req
   prompt = no
   [req_distinguished_name]
   C = US
   ST = VA
   L = SomeCity
   O = MyCompany
   OU = MyDivision
   CN = www.company.com
   [v3_req]
   keyUsage = critical, digitalSignature, keyAgreement
   extendedKeyUsage = serverAuth
   subjectAltName = @alt_names
   [alt_names]
   DNS.1 = www.company.com
   DNS.2 = company.com
   DNS.3 = company.net
   

2. Create the certificate referencing this config file

   openssl req -x509 -nodes -days 730 -newkey rsa:2048 \
    -keyout cert.key -out cert.pem -config req.cnf -sha256
   

Example config from https://support.citrix.com/article/CTX135602

Things change. The escape/unescape methods have been deprecated.

You can URI encode the string before you Base64-encode it. Note that this does't produce Base64-encoded UTF8, but rather Base64-encoded URL-encoded data. Both sides must agree on the same encoding.

See working example here: http://codepen.io/anon/pen/PZgbPW

// encode string
var base64 = window.btoa(encodeURIComponent('€ ?? æøåÆØÅ'));
// decode string
var str = decodeURIComponent(window.atob(tmp));
// str is now === '€ ?? æøåÆØÅ'

For OP's problem a third party library such as js-base64 should solve the problem.

List is an interface and ArrayList is an implementation of the List interface. The ArrayList class has only a few methods(i.e clone(), trimToSize(), removeRange() and ensureCapacity()) in addition to the methods available in the List interface. There is not much difference in this.

   1. List<String> l = new ArrayList<>();
   2. ArrayList<String> l = new ArrayList<>();

If you use the first, you will be able to call the methods available in the List interface and you cannot make calls to the new methods available in the ArrayList class. Where as, you are free to use all the methods available in the ArrayList if you use the second one.

I would say the first approach is a better one because, when you are developing java applications, when you are supposed to pass the collection framework objects as arguments to the methods, then it is better to go with first approach.

List<String> l = new ArrayList<>();
doSomething(l);

In future due to performance constraints, if you are changing the implementation to use LinkedList or someother classes which implements List interface, instead of ArrayList, you need to change at one point only(the instantiation part).

List<String> l = new LinkedList<>();

Else you will be supposed to change at all the places, wherever, you have used the specific class implementation as method arguments.

This is an adaptation from my code for you. I was inspired from developpez.com (Look in the page for : "Pour insérer des données, vaut-il mieux passer par un RecordSet ou par une requête de type INSERT ?"). They explain (with a little French). This way is much faster than the one upper. In the example, this way was 37 times faster. Try it.

Const tableName As String = "InvoiceNumbers"
Const columnIdName As String = "??"
Const columnDateName As String = "date"

Dim rsTable As DAO.recordSet
Dim recordId as long

Set rsTable = CurrentDb.OpenRecordset(tableName)
Call rsTable .AddNew
recordId = CLng(rsTable (columnIdName)) ' Save your Id in a variable
rsTable (columnDateName) = Now()        ' Store your data
rsTable .Update

recordSet.Close

LeCygne

If you make the vertical scale on your chart (using format axis) run from 0.0001 (say) then a value that Excel thinks is zero will not be plotted. Your axis in the chart will still look like it runs from zero upwards.

Rather than explaining the theoretical part, I'll give a simple example.

>>> from collections import OrderedDict
>>> my_dictionary=OrderedDict()
>>> my_dictionary['foo']=3
>>> my_dictionary['aol']=1
>>> my_dictionary
OrderedDict([('foo', 3), ('aol', 1)])
>>> dict(my_dictionary)
{'foo': 3, 'aol': 1}

There is no need to destroy current instance, just refresh.

$('#datepicker')
    .datepicker('option', 'minDate', new Date)
    .datepicker('refresh');

Another possible cause is to have the wrong order of RequestMapping attributes. As spring doc says:

An @RequestMapping handler method can have a very flexible signatures. The supported method arguments and return values are described in the following section. Most arguments can be used in arbitrary order with the only exception of BindingResult arguments. This is described in the next section.

If you scroll down the doc, you will see that the BindingResult has to be immediatelly after the model attribute, since we can have multiple model objects per request and thus multiple bindings

The Errors or BindingResult parameters have to follow the model object that is being bound immediately as the method signature might have more than one model object and Spring will create a separate BindingResult instance for each of them so the following sample won’t work:

Here are two examples:

Invalid ordering of BindingResult and @ModelAttribute.

@RequestMapping(method = RequestMethod.POST) public String processSubmit(@ModelAttribute("pet") Pet pet, Model model, BindingResult result) { ... } Note, that there is a Model parameter in between Pet and BindingResult. To get this working you have to reorder the parameters as follows:

@RequestMapping(method = RequestMethod.POST) public String processSubmit(@ModelAttribute("pet") Pet pet, BindingResult result, Model model) { ... }

This page from Microsoft's Excel VBA documentation helped me: https://docs.microsoft.com/en-us/office/vba/api/excel.xlpastetype

It gives a bunch of options to customize how you paste. For instance, you could xlPasteAll (probably what you're looking for), or xlPasteAllUsingSourceTheme, or even xlPasteAllExceptBorders.

This gets messy with foreign and primary key constraints, so here's some scripts to help you on your way:

First, create a duplicate column with a temporary name:

alter table yourTable add tempId int NOT NULL default -1;
update yourTable set tempId = id;

Next, get the name of your primary key constraint:

SELECT * FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE TABLE_NAME = 'yourTable';

Now try drop the primary key constraint for your column:

ALTER TABLE yourTable DROP CONSTRAINT PK_yourTable_id;

If you have foreign keys, it will fail, so if so drop the foreign key constraints. KEEP TRACK OF WHICH TABLES YOU RUN THIS FOR SO YOU CAN ADD THE CONSTRAINTS BACK IN LATER!!!

SELECT * FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE TABLE_NAME = 'otherTable';
alter table otherTable drop constraint fk_otherTable_yourTable;
commit;
..

Once all of your foreign key constraints have been removed, you'll be able to remove the PK constraint, drop that column, rename your temp column, and add the PK constraint to that column:

ALTER TABLE yourTable DROP CONSTRAINT PK_yourTable_id;
alter table yourTable drop column id;
EXEC sp_rename 'yourTable.tempId', 'id', 'COLUMN';
ALTER TABLE yourTable ADD CONSTRAINT PK_yourTable_id PRIMARY KEY (id) 
commit;

Finally, add the FK constraints back in:

alter table otherTable add constraint fk_otherTable_yourTable foreign key (yourTable_id) references yourTable(id);
..

El Fin!

You can do this be using a new Subject too:

Typescript:

let subject = new Subject();

get_categories(...) {
   this.http.post(...).subscribe( 
      (response) => {
         this.total = response.json();
         subject.next();
      }
   ); 

   return subject; // can be subscribed as well 
}

get_categories(...).subscribe(
   (response) => {
     // ...
   }
);

Implement repr for every class you implement. There should be no excuse. Implement str for classes which you think readability is more important of non-ambiguity.

Refer this link: https://www.pythoncentral.io/what-is-the-difference-between-str-and-repr-in-python/

Data-Binding

You go around making your webpage, and keep on putting {{data bindings}} whenever you feel you would have dynamic data. Angular will then provide you a $scope handler, which you can populate (statically or through calls to the web server).

This is a good understanding of data-binding. I think you've got that down.

DOM Manipulation

For simple DOM manipulation, which doesnot involve data manipulation (eg: color changes on mousehover, hiding/showing elements on click), jQuery or old-school js is sufficient and cleaner. This assumes that the model in angular's mvc is anything that reflects data on the page, and hence, css properties like color, display/hide, etc changes dont affect the model.

I can see your point here about "simple" DOM manipulation being cleaner, but only rarely and it would have to be really "simple". I think DOM manipulation is one the areas, just like data-binding, where Angular really shines. Understanding this will also help you see how Angular considers its views.

I'll start by comparing the Angular way with a vanilla js approach to DOM manipulation. Traditionally, we think of HTML as not "doing" anything and write it as such. So, inline js, like "onclick", etc are bad practice because they put the "doing" in the context of HTML, which doesn't "do". Angular flips that concept on its head. As you're writing your view, you think of HTML as being able to "do" lots of things. This capability is abstracted away in angular directives, but if they already exist or you have written them, you don't have to consider "how" it is done, you just use the power made available to you in this "augmented" HTML that angular allows you to use. This also means that ALL of your view logic is truly contained in the view, not in your javascript files. Again, the reasoning is that the directives written in your javascript files could be considered to be increasing the capability of HTML, so you let the DOM worry about manipulating itself (so to speak). I'll demonstrate with a simple example.

This is the markup we want to use. I gave it an intuitive name.

<div rotate-on-click="45"></div>

First, I'd just like to comment that if we've given our HTML this functionality via a custom Angular Directive, we're already done. That's a breath of fresh air. More on that in a moment.

Implementation with jQuery

live demo here (click).

function rotate(deg, elem) {
  $(elem).css({
    webkitTransform: 'rotate('+deg+'deg)', 
    mozTransform: 'rotate('+deg+'deg)', 
    msTransform: 'rotate('+deg+'deg)', 
    oTransform: 'rotate('+deg+'deg)', 
    transform: 'rotate('+deg+'deg)'    
  });
}

function addRotateOnClick($elems) {
  $elems.each(function(i, elem) {
    var deg = 0;
    $(elem).click(function() {
      deg+= parseInt($(this).attr('rotate-on-click'), 10);
      rotate(deg, this);
    });
  });
}

addRotateOnClick($('[rotate-on-click]'));

Implementation with Angular

live demo here (click).

app.directive('rotateOnClick', function() {
  return {
    restrict: 'A',
    link: function(scope, element, attrs) {
      var deg = 0;
      element.bind('click', function() {
        deg+= parseInt(attrs.rotateOnClick, 10);
        element.css({
          webkitTransform: 'rotate('+deg+'deg)', 
          mozTransform: 'rotate('+deg+'deg)', 
          msTransform: 'rotate('+deg+'deg)', 
          oTransform: 'rotate('+deg+'deg)', 
          transform: 'rotate('+deg+'deg)'    
        });
      });
    }
  };
});

Pretty light, VERY clean and that's just a simple manipulation! In my opinion, the angular approach wins in all regards, especially how the functionality is abstracted away and the dom manipulation is declared in the DOM. The functionality is hooked onto the element via an html attribute, so there is no need to query the DOM via a selector, and we've got two nice closures - one closure for the directive factory where variables are shared across all usages of the directive, and one closure for each usage of the directive in the link function (or compile function).

Two-way data binding and directives for DOM manipulation are only the start of what makes Angular awesome. Angular promotes all code being modular, reusable, and easily testable and also includes a single-page app routing system. It is important to note that jQuery is a library of commonly needed convenience/cross-browser methods, but Angular is a full featured framework for creating single page apps. The angular script actually includes its own "lite" version of jQuery so that some of the most essential methods are available. Therefore, you could argue that using Angular IS using jQuery (lightly), but Angular provides much more "magic" to help you in the process of creating apps.

This is a great post for more related information: How do I “think in AngularJS” if I have a jQuery background?

General differences.

The above points are aimed at the OP's specific concerns. I'll also give an overview of the other important differences. I suggest doing additional reading about each topic as well.

Angular and jQuery can't reasonably be compared.

Angular is a framework, jQuery is a library. Frameworks have their place and libraries have their place. However, there is no question that a good framework has more power in writing an application than a library. That's exactly the point of a framework. You're welcome to write your code in plain JS, or you can add in a library of common functions, or you can add a framework to drastically reduce the code you need to accomplish most things. Therefore, a more appropriate question is:

Why use a framework?

Good frameworks can help architect your code so that it is modular (therefore reusable), DRY, readable, performant and secure. jQuery is not a framework, so it doesn't help in these regards. We've all seen the typical walls of jQuery spaghetti code. This isn't jQuery's fault - it's the fault of developers that don't know how to architect code. However, if the devs did know how to architect code, they would end up writing some kind of minimal "framework" to provide the foundation (achitecture, etc) I discussed a moment ago, or they would add something in. For example, you might add RequireJS to act as part of your framework for writing good code.

Here are some things that modern frameworks are providing:

• Templating
• Data-binding
• routing (single page app)
• clean, modular, reusable architecture
• security
• additional functions/features for convenience

Before I further discuss Angular, I'd like to point out that Angular isn't the only one of its kind. Durandal, for example, is a framework built on top of jQuery, Knockout, and RequireJS. Again, jQuery cannot, by itself, provide what Knockout, RequireJS, and the whole framework built on top them can. It's just not comparable.

If you need to destroy a planet and you have a Death Star, use the Death star.

Angular (revisited).

Building on my previous points about what frameworks provide, I'd like to commend the way that Angular provides them and try to clarify why this is matter of factually superior to jQuery alone.

DOM reference.

In my above example, it is just absolutely unavoidable that jQuery has to hook onto the DOM in order to provide functionality. That means that the view (html) is concerned about functionality (because it is labeled with some kind of identifier - like "image slider") and JavaScript is concerned about providing that functionality. Angular eliminates that concept via abstraction. Properly written code with Angular means that the view is able to declare its own behavior. If I want to display a clock:

<clock></clock>

Done.

Yes, we need to go to JavaScript to make that mean something, but we're doing this in the opposite way of the jQuery approach. Our Angular directive (which is in it's own little world) has "augumented" the html and the html hooks the functionality into itself.

MVW Architecure / Modules / Dependency Injection

Angular gives you a straightforward way to structure your code. View things belong in the view (html), augmented view functionality belongs in directives, other logic (like ajax calls) and functions belong in services, and the connection of services and logic to the view belongs in controllers. There are some other angular components as well that help deal with configuration and modification of services, etc. Any functionality you create is automatically available anywhere you need it via the Injector subsystem which takes care of Dependency Injection throughout the application. When writing an application (module), I break it up into other reusable modules, each with their own reusable components, and then include them in the bigger project. Once you solve a problem with Angular, you've automatically solved it in a way that is useful and structured for reuse in the future and easily included in the next project. A HUGE bonus to all of this is that your code will be much easier to test.

It isn't easy to make things "work" in Angular.

THANK GOODNESS. The aforementioned jQuery spaghetti code resulted from a dev that made something "work" and then moved on. You can write bad Angular code, but it's much more difficult to do so, because Angular will fight you about it. This means that you have to take advantage (at least somewhat) to the clean architecture it provides. In other words, it's harder to write bad code with Angular, but more convenient to write clean code.

Angular is far from perfect. The web development world is always growing and changing and there are new and better ways being put forth to solve problems. Facebook's React and Flux, for example, have some great advantages over Angular, but come with their own drawbacks. Nothing's perfect, but Angular has been and is still awesome for now. Just as jQuery once helped the web world move forward, so has Angular, and so will many to come.

This is my work around:

1) Add a wrapper div to the recaptcha div.

<div id="recaptcha-wrapper"><div class="g-recaptcha" data-sitekey="..."></div></div>

2) Add javascript/jquery code.

$(function(){
    // global variables
    captchaResized = false;
    captchaWidth = 304;
    captchaHeight = 78;
    captchaWrapper = $('#recaptcha-wrapper');
    captchaElements = $('#rc-imageselect, .g-recaptcha');

    resizeCaptcha();
    $(window).on('resize', function() {
        resizeCaptcha();
    });
});

function resizeCaptcha() {
    if (captchaWrapper.width() >= captchaWidth) {
        if (captchaResized) {
            captchaElements.css('transform', '').css('-webkit-transform', '').css('-ms-transform', '').css('-o-transform', '').css('transform-origin', '').css('-webkit-transform-origin', '').css('-ms-transform-origin', '').css('-o-transform-origin', '');
            captchaWrapper.height(captchaHeight);
            captchaResized = false;
        }
    } else {
        var scale = (1 - (captchaWidth - captchaWrapper.width()) * (0.05/15));
        captchaElements.css('transform', 'scale('+scale+')').css('-webkit-transform', 'scale('+scale+')').css('-ms-transform', 'scale('+scale+')').css('-o-transform', 'scale('+scale+')').css('transform-origin', '0 0').css('-webkit-transform-origin', '0 0').css('-ms-transform-origin', '0 0').css('-o-transform-origin', '0 0');
        captchaWrapper.height(captchaHeight * scale);
        if (captchaResized == false) captchaResized = true;
    }
}

3) Optional: add some styling if needed.

#recaptcha-wrapper { text-align:center; margin-bottom:15px; }

.g-recaptcha { display:inline-block; }

You can access characters in strings in the same way as you would access an array index, e.g.

$length = strlen($string);
$thisWordCodeVerdeeld = array();
for ($i=0; $i<$length; $i++) {
    $thisWordCodeVerdeeld[$i] = $string[$i];
}

You could also do:

$thisWordCodeVerdeeld = str_split($string);

However you might find it is easier to validate the string as a whole string, e.g. using regular expressions.

Using dplyr:

If all images are of the same format:

import cv2
import glob

images = [cv2.imread(file) for file in glob.glob('path/to/files/*.jpg')]

For reading images of different formats:

import cv2
import glob

imdir = 'path/to/files/'
ext = ['png', 'jpg', 'gif']    # Add image formats here

files = []
[files.extend(glob.glob(imdir + '*.' + e)) for e in ext]

images = [cv2.imread(file) for file in files]

var jsonIssues = [
 {ID:'1',Name:'Some name',Notes:'NOTES'},
 {ID:'2',Name:'Some name 2',Notes:'NOTES 2'}
];

If you want to add to the array then you can do this

jsonIssues[jsonIssues.length] = {ID:'3',Name:'Some name 3',Notes:'NOTES 3'};

Or you can use the push technique that the other guy posted, which is also good.

Use tail command:

ls -t | tail -n 5

Rather than changing owners, which might lock out other local users, or –some day– your own ruby server/deployment-things... running under a different user...

I would rather simply extend rights of that particular folder to... well, everybody:

cd /var/lib
sudo chmod -R a+w gems/

(I did encounter your error as well. So this is fairly verified.)

Or

public class Section
{
  public String Head { get; set; }
  private readonly List<string> _subHead = new List<string>();
  private readonly List<string> _content = new List<string>();

  public IEnumerable<string> SubHead { get { return _subHead; } }
  public IEnumerable<string> Content { get { return _content; } }

  public void AddContent(String argValue)
  {
    _content.Add(argValue);
  }

  public void AddSubHeader(String argValue)
  {
    _subHead.Add(argValue);
  }
}

All depends on how much of the implementaton of content and subhead you want to hide.

Currently there is a far simpler solution than the ones already provided. When running your application you just have to pass along the threaded=True parameter to the app.run() call, like:

app.run(host="your.host", port=4321, threaded=True)

Another option as per what we can see in the werkzeug docs, is to use the processes parameter, which receives a number > 1 indicating the maximum number of concurrent processes to handle:

• threaded – should the process handle each request in a separate thread?
• processes – if greater than 1 then handle each request in a new process up to this maximum number of concurrent processes.

Something like:

app.run(host="your.host", port=4321, processes=3) #up to 3 processes

More info on the run() method here, and the blog post that led me to find the solution and api references.

Note: on the Flask docs on the run() methods it's indicated that using it in a Production Environment is discouraged because (quote): "While lightweight and easy to use, Flask’s built-in server is not suitable for production as it doesn’t scale well."

However, they do point to their Deployment Options page for the recommended ways to do this when going for production.

Complete answer is located in the official PostgreSQL documentation.

You can use new PG9.0 anonymous code block feature (http://www.postgresql.org/docs/9.1/static/sql-do.html )

DO $$
DECLARE v_List TEXT;
BEGIN
  v_List := 'foobar' ;
  SELECT *
  FROM   dbo.PubLists
  WHERE  Name = v_List;
  -- ...
END $$;

Also you can get the last insert id:

DO $$
DECLARE lastid bigint;
BEGIN
  INSERT INTO test (name) VALUES ('Test Name') 
  RETURNING id INTO lastid;

  SELECT * FROM test WHERE id = lastid;
END $$;

Whilst the accepted answer works and is good for Linq to Objects it bugged me that the SQL query isn't just a straight Left Outer Join.

The following code relies on the LinkKit Project that allows you to pass expressions and invoke them to your query.

static IQueryable<TResult> LeftOuterJoin<TSource,TInner, TKey, TResult>(
     this IQueryable<TSource> source, 
     IQueryable<TInner> inner, 
     Expression<Func<TSource,TKey>> sourceKey, 
     Expression<Func<TInner,TKey>> innerKey, 
     Expression<Func<TSource, TInner, TResult>> result
    ) {
    return from a in source.AsExpandable()
            join b in inner on sourceKey.Invoke(a) equals innerKey.Invoke(b) into c
            from d in c.DefaultIfEmpty()
            select result.Invoke(a,d);
}

It can be used as follows

Table1.LeftOuterJoin(Table2, x => x.Key1, x => x.Key2, (x,y) => new { x,y});

As ibram stated, add the manifest thru solution explorer:

You can also visit the feed url directly in your browser. You may end up with a response that contains a message like this, which may make your diagnosis a lot quicker:

Logically OLAP functions are calculated after GROUP BY/HAVING, so you can only access columns in GROUP BY or columns with an aggregate function. Following looks strange, but is Standard SQL:

SELECT employee_number,
       MAX(MAX(course_completion_date)) 
           OVER (PARTITION BY course_code) AS max_course_date,
       MAX(course_completion_date) AS max_date
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code

And as Teradata allows re-using an alias this also works:

SELECT employee_number,
       MAX(max_date) 
           OVER (PARTITION BY course_code) AS max_course_date,
       MAX(course_completion_date) AS max_date
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code

I tried this code, it may work for you also:

            DateFormat dateFormat2 = new SimpleDateFormat("dd"); 
            Date date2 = new Date();

            String today = dateFormat2.format(date2); 

            //find the calendar
            WebElement dateWidget = driver.findElement(By.id("dp-calendar"));  
            List<WebElement> columns=dateWidget.findElements(By.tagName("td"));  

            //comparing the text of cell with today's date and clicking it.
            for (WebElement cell : columns)
            {
               if (cell.getText().equals(today))
               {
                  cell.click();
                  break;
               }
            }

Almost done. Quoting from http://docs.python.org/library/stdtypes.html?highlight=strip#str.strip

The chars argument is a string specifying the set of characters to be removed.

[...]

The chars argument is not a prefix or suffix; rather, all combinations of its values are stripped:

So the argument is not a regexp.

>>> string = '"" " " ""\\1" " "" ""'
>>> string.strip('"')
' " " ""\\1" " "" '
>>> 

Note, that this is not exactly what you requested, because it eats multiple quotes from both end of the string!

If you can't just use filter join but need to perform some operations on the array's entry:

{% for entry in array %}
User {{ entry.attribute1 }} has id {{ entry.attribute2 }}
{% if not loop.last %}, {% endif %}
{% endfor %}

I would rather put my answer in How to flush output of print function? or in Python's print function that flushes the buffer when it's called?, but since they were marked as duplicates of this one (what I do not agree), I'll answer it here.

Since Python 3.3, print() supports the keyword argument "flush" (see documentation):

print('Hello World!', flush=True)

"saving" is something wholly different from changing paragraph content with jquery.

If you need to save changes you will have to write them to your server somehow (likely form submission along with all the security and input sanitizing that entails). If you have information that is saved on the server then you are no longer changing the content of a paragraph, you are drawing a paragraph with dynamic content (either from a database or a file which your server altered when you did the "saving").

Judging by your question, this is a topic on which you will have to do MUCH more research.

Input page (input.html):

<form action="/saveMyParagraph.php">
    <input name="pContent" type="text"></input>
</form>

Saving page (saveMyParagraph.php) and Ouput page (output.php):

For Mac users

Here is @Joseph's accepted answer, but with the default Mac install path location of kdiff3

(Note that you can copy and paste this and run it in one go)

git config --global --add merge.tool kdiff3 
git config --global --add mergetool.kdiff3.path  "/Applications/kdiff3.app/Contents/MacOS/kdiff3" 
git config --global --add mergetool.kdiff3.trustExitCode false

git config --global --add diff.guitool kdiff3
git config --global --add difftool.kdiff3.path "/Applications/kdiff3.app/Contents/MacOS/kdiff3"
git config --global --add difftool.kdiff3.trustExitCode false

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

I had similar problem. I needed to write down csv file on driver while I was connect to cluster in client mode.

I wanted to reuse the same CSV parsing code as Apache Spark to avoid potential errors.

I checked spark-csv code and found code responsible for converting dataframe into raw csv RDD[String] in com.databricks.spark.csv.CsvSchemaRDD.

Sadly it is hardcoded with sc.textFile and the end of relevant method.

I copy-pasted that code and removed last lines with sc.textFile and returned RDD directly instead.

My code:

/*
  This is copypasta from com.databricks.spark.csv.CsvSchemaRDD
  Spark's code has perfect method converting Dataframe -> raw csv RDD[String]
  But in last lines of that method it's hardcoded against writing as text file -
  for our case we need RDD.

Pygmentize + Python json.tool = Pretty Print with Syntax Highlighting

Pygmentize is a killer tool. See this.

I combine python json.tool with pygmentize

echo '{"foo": "bar"}' | python -m json.tool | pygmentize -l json

See the link above for pygmentize installation instruction.

A demo of this is in the image below:

As mentioned in other answers, by default div will be rendered as a block element, while span will be rendered inline within its context. But neither has any semantic value; they exist to allow you to apply styling and an identity to any given bit of content. Using styles, you can make a div act like a span and vice-versa.

One of the useful styles for div is inline-block

Examples:

1. http://dustwell.com/div-span-inline-block.html

2. CSS display: inline vs inline-block

I have used inline-block to a great success, in game web projects.

Stub, Fakes and Mocks have different meanings across different sources. I suggest you to introduce your team internal terms and agree upon their meaning.

I think it is important to distinguish between two approaches: - behaviour validation (implies behaviour substitution) - end-state validation (implies behaviour emulation)

Consider email sending in case of error. When doing behaviour validation - you check that method Send of IEmailSender was executed once. And you need to emulate return result of this method, return Id of the sent message. So you say: "I expect that Send will be called. And I will just return dummy (or random) Id for any call". This is behaviour validation: emailSender.Expect(es=>es.Send(anyThing)).Return((subject,body) => "dummyId")

When doing state validation you will need to create TestEmailSender that implements IEmailSender. And implement Send method - by saving input to some data structure that will be used for future state verification like array of some objects SentEmails and then it tests you will check that SentEmails contains expected email. This is state validation: Assert.AreEqual(1, emailSender.SentEmails.Count)

From my readings I understood that Behaviour validation usually called Mocks. And State validation usually called Stubs or Fakes.

In-order to make SQL server send email notification you need to create mail profile from Management, database mail.

1) User Right click to get the mail profile menu and choose configure database mail

2)choose the first open (set up a database mail by following the following tasks) and press next Note: if the SMTP is not configured please refer the the URL below

http://www.symantec.com/business/support/index?page=content&id=TECH86263

3) in the second screen fill the the profile name and add SMTP account, then press next

4) choose the type of mail account ( public or private ) then press next

5) change the parameters that related to the sending mail options, and press next 6) press finish

Now to make SQL server send an email if action X happened you can do that via trigger or job ( This is the common ways not the only ones).

1) you can create Job from SQL server agent, then right click on operators and check mails (fill the your email for example) and press OK after that right click Jobs and choose new job and fill the required info as well as the from steps, name, ...etc and from notification tab select the profile you made.

2) from triggers please refer to the example below.

AS
declare @results varchar(max)
declare @subjectText varchar(max)
declare @databaseName VARCHAR(255)
SET @subjectText = 'your subject'
SET @results = 'your results'
-- write the Trigger JOB
EXEC msdb.dbo.sp_send_dbmail
 @profile_name = 'SQLAlerts',
 @recipients = '[email protected]',
 @body = @results,
 @subject = @subjectText,
 @exclude_query_output = 1 --Suppress 'Mail Queued' message

Use the Office FileDialog object to have the user pick a file from the filesystem. Add a reference in your VB project or in the VBA editor to Microsoft Office Library and look in the help. This is much better than having people enter full paths.

Here is an example using msoFileDialogFilePicker to allow the user to choose multiple files. You could also use msoFileDialogOpen.

'Note: this is Excel VBA code
Public Sub LogReader()
    Dim Pos As Long
    Dim Dialog As Office.FileDialog
    Set Dialog = Application.FileDialog(msoFileDialogFilePicker)

    With Dialog
        .AllowMultiSelect = True
        .ButtonName = "C&onvert"
        .Filters.Clear
        .Filters.Add "Log Files", "*.log", 1
        .Title = "Convert Logs to Excel Files"
        .InitialFileName = "C:\InitialPath\"
        .InitialView = msoFileDialogViewList

        If .Show Then
            For Pos = 1 To .SelectedItems.Count
                LogRead .SelectedItems.Item(Pos) ' process each file
            Next
        End If
    End With
End Sub

There are lots of options, so you'll need to see the full help files to understand all that is possible. You could start with Office 2007 FileDialog object (of course, you'll need to find the correct help for the version you're using).

Try this:

MyContext Context = new MyContext(); 
Context.YourEntity.Add(obj);
Context.SaveChanges();

The problem is in the sequence 0xe2 0x80 0x8b, which precedes https. This sequence is a ZERO WIDTH JOINER encoded in UTF-8.

The solution below uses a double loop to add data to the bottom of a 2x2 array in the Case 3. The inner loop pushes selected elements' values into a new row array. The outerloop then pushes the new row array to the bottom of an existing array (see Newbie: Add values to two-dimensional array with for loops, Google Apps Script).

In this example, I created a function that extracts a section from an existing array. The extracted section can be a row (full or partial), a column (full or partial), or a 2x2 section of the existing array. A new blank array (newArr) is filled by pushing the relevant section from the existing array (arr) into the new array.

 function arraySection(arr, r1, c1, rLength, cLength) {      
   rowMax = arr.length;
    if(isNaN(rowMax)){rowMax = 1};
   colMax = arr[0].length;
   if(isNaN(colMax)){colMax = 1};
   var r2 = r1 + rLength - 1;
   var c2 = c1 + cLength - 1;

   if ((r1< 0 || r1 > r2 || r1 > rowMax || (r1 | 0) != r1) || (r2 < 0 || 
     r2 > rowMax || (r2 | 0) != r2)|| (c1< 0 || c1 > c2 || c1 > colMax || 
   (c1 | 0) != c1) ||(c2 < 0 || c2 > colMax || (c2 | 0) != c2)){
        throw new Error(
        'arraySection: invalid input')       
        return;
     };
   var newArr = [];

// Case 1: extracted section is a column array, 
//          all elements are in the same column
 if (c1 == c2){
   for (var i = r1; i <= r2; i++){ 
         // Logger.log("arr[i][c1] for i = " + i);
         // Logger.log(arr[i][c1]);
     newArr.push([arr[i][c1]]); 
     };
    };  

// Case 2: extracted section is a row array, 
//          all elements are in the same row
  if (r1 == r2 && c1 != c2){
    for (var j = c1; j <= c2; j++){ 
      newArr.push(arr[r1][j]); 
      };
   };  

// Case 3: extracted section is a 2x2 section 
    if (r1 != r2 && c1 != c2){     
     for (var i = r1; i <= r2; i++) {
          rowi = [];
       for (var j = c1; j <= c2; j++) {
          rowi.push(arr[i][j]);
        }
       newArr.push(rowi)
      };
    };
   return(newArr);
  };

As other folks already mention, I will suggest not to use "sudo apt-get" to install node or any development library. You can download required version from https://nodejs.org/dist/v6.9.2/ and setup you own environment.

I will recommend tools like nvm and n, to manage you node version. It is very convenient to switch and work with these modules. https://github.com/creationix/nvm https://github.com/tj/n

Or write basic bash to download zip/tar, extract move folder and create a soft link. Whenever you need to update, just point the old soft link to new downloaded version. Like I have created for my own, you can refer: https://github.com/deepakshrma/NodeJs-4.0-Reference-Guide/blob/master/nodejs-installer.sh

I suppose that you needed that in form of a script, but if someone else just want to have a look through the Jenkins GUI, that list can be found by selecting the "Environment Variables" section in contextual left menu of every build Select project => Select build => Environment Variables

You can use:

WHERE LEFT (name_field, 1) = 'B';

Remember that the "folders/groups" you make in xcode, those which are yellowish are not reflected as real folders in your iPhone app. They are just there to structure your XCode project. You can nest as many yellow group as you want and they still only serve the purpose of organizing code in XCode.

EDIT

Make a folder outside of XCode then drag it over, and select "Create folder references for any added folders" instead of "Create groups for any added folders" in the popup.

in Swift 4.2 it is a property now.

override var prefersStatusBarHidden: Bool {
    return true
}

In Python3 iteritems() is no longer supported

Use .items

for field, possible_values in fields.items():
    print(field, possible_values)

What does the percentage sign mean?

It's an operator in Python that can mean several things depending on the context. A lot of what follows was already mentioned (or hinted at) in the other answers but I thought it could be helpful to provide a more extensive summary.

% for Numbers: Modulo operation / Remainder / Rest

The percentage sign is an operator in Python. It's described as:

x % y       remainder of x / y

So it gives you the remainder/rest that remains if you "floor divide" x by y. Generally (at least in Python) given a number x and a divisor y:

x == y * (x // y) + (x % y)

For example if you divide 5 by 2:

>>> 5 // 2
2
>>> 5 % 2
1

>>> 2 * (5 // 2) + (5 % 2)
5

In general you use the modulo operation to test if a number divides evenly by another number, that's because multiples of a number modulo that number returns 0:

>>> 15 % 5  # 15 is 3 * 5
0

>>> 81 % 9  # 81 is 9 * 9
0

That's how it's used in your example, it cannot be a prime if it's a multiple of another number (except for itself and one), that's what this does:

if n % x == 0:
    break

If you feel that n % x == 0 isn't very descriptive you could put it in another function with a more descriptive name:

def is_multiple(number, divisor):
    return number % divisor == 0

...

if is_multiple(n, x):
    break

Instead of is_multiple it could also be named evenly_divides or something similar. That's what is tested here.

Similar to that it's often used to determine if a number is "odd" or "even":

def is_odd(number):
    return number % 2 == 1

def is_even(number):
    return number % 2 == 0

And in some cases it's also used for array/list indexing when wrap-around (cycling) behavior is wanted, then you just modulo the "index" by the "length of the array" to achieve that:

>>> l = [0, 1, 2]
>>> length = len(l)
>>> for index in range(10):
...     print(l[index % length])
0
1
2
0
1
2
0
1
2
0

Note that there is also a function for this operator in the standard library operator.mod (and the alias operator.__mod__):

>>> import operator
>>> operator.mod(5, 2)  # equivalent to 5 % 2
1

But there is also the augmented assignment %= which assigns the result back to the variable:

>>> a = 5
>>> a %= 2  # identical to: a = a % 2
>>> a
1

% for strings: printf-style String Formatting

For strings the meaning is completely different, there it's one way (in my opinion the most limited and ugly) for doing string formatting:

>>> "%s is %s." % ("this", "good") 
'this is good'

Here the % in the string represents a placeholder followed by a formatting specification. In this case I used %s which means that it expects a string. Then the string is followed by a % which indicates that the string on the left hand side will be formatted by the right hand side. In this case the first %s is replaced by the first argument this and the second %s is replaced by the second argument (good).

Note that there are much better (probably opinion-based) ways to format strings:

>>> "{} is {}.".format("this", "good")
'this is good.'

% in Jupyter/IPython: magic commands

To quote the docs:

To Jupyter users: Magics are specific to and provided by the IPython kernel. Whether magics are available on a kernel is a decision that is made by the kernel developer on a per-kernel basis. To work properly, Magics must use a syntax element which is not valid in the underlying language. For example, the IPython kernel uses the % syntax element for magics as % is not a valid unary operator in Python. While, the syntax element has meaning in other languages.

This is regularly used in Jupyter notebooks and similar:

In [1]:  a = 10
         b = 20
         %timeit a + b   # one % -> line-magic

54.6 ns ± 2.7 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

In [2]:  %%timeit  # two %% -> cell magic 
         a ** b

362 ns ± 8.4 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

The % operator on arrays (in the NumPy / Pandas ecosystem)

The % operator is still the modulo operator when applied to these arrays, but it returns an array containing the remainder of each element in the array:

>>> import numpy as np
>>> a = np.arange(10)
>>> a
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])

>>> a % 2
array([0, 1, 0, 1, 0, 1, 0, 1, 0, 1])

Customizing the % operator for your own classes

Of course you can customize how your own classes work when the % operator is applied to them. Generally you should only use it to implement modulo operations! But that's a guideline, not a hard rule.

Just to provide a simple example that shows how it works:

class MyNumber(object):
    def __init__(self, value):
        self.value = value

    def __mod__(self, other):
        print("__mod__ called on '{!r}'".format(self))
        return self.value % other

    def __repr__(self):
        return "{self.__class__.__name__}({self.value!r})".format(self=self)

This example isn't really useful, it just prints and then delegates the operator to the stored value, but it shows that __mod__ is called when % is applied to an instance:

>>> a = MyNumber(10)
>>> a % 2
__mod__ called on 'MyNumber(10)'
0

Note that it also works for %= without explicitly needing to implement __imod__:

>>> a = MyNumber(10)
>>> a %= 2
__mod__ called on 'MyNumber(10)'

>>> a
0

However you could also implement __imod__ explicitly to overwrite the augmented assignment:

class MyNumber(object):
    def __init__(self, value):
        self.value = value

    def __mod__(self, other):
        print("__mod__ called on '{!r}'".format(self))
        return self.value % other

    def __imod__(self, other):
        print("__imod__ called on '{!r}'".format(self))
        self.value %= other
        return self

    def __repr__(self):
        return "{self.__class__.__name__}({self.value!r})".format(self=self)

Now %= is explicitly overwritten to work in-place:

>>> a = MyNumber(10)
>>> a %= 2
__imod__ called on 'MyNumber(10)'

>>> a
MyNumber(0)

In C, there's no (real, distinct type of) strings. Every C "string" is an array of chars, zero terminated.

Therefore, to extract a character c at index i from string your_string, just use

char c = your_string[i];

Index is base 0 (first character is your_string[0], second is your_string[1]...).

Use .. LIMIT :pageSize OFFSET :pageStart

Where :pageStart is bound to the_page_index (i.e. 0 for the first page) * number_of_items_per_pages (e.g. 4) and :pageSize is bound to number_of_items_per_pages.

To detect for "has more pages", either use SQL_CALC_FOUND_ROWS or use .. LIMIT :pageSize OFFSET :pageStart + 1 and detect a missing last (pageSize+1) record. Needless to say, for pages with an index > 0, there exists a previous page.

If the page index value is embedded in the URL (e.g. in "prev page" and "next page" links) then it can be obtained via the appropriate $_GET item.

Time 30 minutes later

$newTime = date("Y-m-d H:i:s",strtotime(date("Y-m-d H:i:s")." +30 minutes"))

Change alert(buttons[i].text); to alert(i);

I have read multiple threads and none of them fixed the issue that people are describing and I have experienced too.

I have even tried to move away from conda and use pip, to upgrade to python 3.7, i have tried all coding proposed and none of them fixed.

And here is why (the problem):

by default python/flask search the static and the template in a folder structure like:

/Users/username/folder_one/folder_two/ProjectName/src/app_name/<static>
 and 
/Users/username/folder_one/folder_two/ProjectName/src/app_name/<template>

you can verify by yourself using the debugger on Pycharm (or anything else) and check the values on the app (app = Flask(name)) and search for teamplate_folder and static_folder

in order to fix this, you have to specify the values when creating the app something like this:

TEMPLATE_DIR = os.path.abspath('../templates')
STATIC_DIR = os.path.abspath('../static')

# app = Flask(__name__) # to make the app run without any
app = Flask(__name__, template_folder=TEMPLATE_DIR, static_folder=STATIC_DIR)

the path TEMPLATE_DIR and STATIC_DIR depend on where the file app is located. in my case, see the picture, it was located within a folder under src.

you can change the template and static folders as you wish and register on the app = Flask...

In truth, I have started experiencing the problem when messing around with folder and at times worked at times not. this fixes the problem once and for all

the html code looks like this:

<link href="{{ url_for('static', filename='libraries/css/bootstrap.css') }}" rel="stylesheet" type="text/css" >

This the code

Here the structure of the folders

When creating AVD,

1. Pick a device with google play icon.

2. Pick the google play version of the image, of your desired API level.

Now, after creating the AVD, you should see the google play icon .

Using JSTL:

<c:set var="message" value='${requestScope["Error_Message"]}' />

Here var sets the variable name and request.getAttribute is equal to requestScope. But it's not essential. ${Error_Message} will give you the same outcome. It'll search every scope. If you want to do some operation with content you take from Error_Message you have to do it using message. like below one.

<c:out value="${message}"/>

The method to change the color, position and background color of toast is:

Toast toast=Toast.makeText(getApplicationContext(),"This is advanced toast",Toast.LENGTH_LONG);
toast.setGravity(Gravity.BOTTOM | Gravity.RIGHT,0,0);
View view=toast.getView();
TextView  view1=(TextView)view.findViewById(android.R.id.message);
view1.setTextColor(Color.YELLOW);
view.setBackgroundResource(R.color.colorPrimary);
toast.show();

The real answer has to include keyCode:

var e = jQuery.Event("keydown");
e.which = 50; // # Some key code value
e.keyCode = 50
$("input").trigger(e);

Even though jQuery's website says that which and keyCode are normalized they are very badly mistaken. It's always safest to do the standard cross-browser checks for e.which and e.keyCode and in this case just define both.

There are a few ways, not including a custom COM or ActiveX object

1. ReDim Preserve
2. Dictionary object, which can have string keys and search for them
3. ArrayList .Net Framework Class, which has many methods including: sort (forward, reverse, custom), insert, remove, binarysearch, equals, toArray, and toString

With the code below, I found Redim Preserve is fastest below 54000, Dictionary is fastest from 54000 to 690000, and Array List is fastest above 690000. I tend to use ArrayList for pushing because of the sorting and array conversion.

user326639 provided FastArray, which is pretty much the fastest.

Dictionaries are useful for searching for the value and returning the index (i.e. field names), or for grouping and aggregation (histograms, group and add, group and concatenate strings, group and push sub-arrays). When grouping on keys, set CompareMode for case in/sensitivity, and check the "exists" property before "add"-ing.

Redim wouldn't save much time for one array, but it's useful for a dictionary of arrays.

To send a message to a user you first need a User instance representing the user you want to send the message to.

Obtaining a User instance

• You can obtain a User instance from a message the user sent by doing message.autor
• You can obtain a User instance from a user id with client.fetchUser

Once you got a user instance you can send the message with .send

Examples

client.on('message', (msg) => {
 if (!msg.author.bot) msg.author.send('ok ' + msg.author.id);
});

client.fetchUser('487904509670337509', false).then((user) => {
 user.send('heloo');
});

for linux (bash) following code works for me:

System.out.print("\033[31mERROR  \033[0m");

the \033[31m will switch the color to red and \033[0m will switch it back to normal.

A logical address is a reference to memory location independent of the current assignment of data to memory. A physical address or absolute address is an actual location in main memory.

It is in chapter 7.2 of Stallings.

Integrated application pool mode

When an application pool is in Integrated mode, you can take advantage of the integrated request-processing architecture of IIS and ASP.NET. When a worker process in an application pool receives a request, the request passes through an ordered list of events. Each event calls the necessary native and managed modules to process portions of the request and to generate the response.

There are several benefits to running application pools in Integrated mode. First the request-processing models of IIS and ASP.NET are integrated into a unified process model. This model eliminates steps that were previously duplicated in IIS and ASP.NET, such as authentication. Additionally, Integrated mode enables the availability of managed features to all content types.

Classic application pool mode

When an application pool is in Classic mode, IIS 7.0 handles requests as in IIS 6.0 worker process isolation mode. ASP.NET requests first go through native processing steps in IIS and are then routed to Aspnet_isapi.dll for processing of managed code in the managed runtime. Finally, the request is routed back through IIS to send the response.

This separation of the IIS and ASP.NET request-processing models results in duplication of some processing steps, such as authentication and authorization. Additionally, managed code features, such as forms authentication, are only available to ASP.NET applications or applications for which you have script mapped all requests to be handled by aspnet_isapi.dll.

Be sure to test your existing applications for compatibility in Integrated mode before upgrading a production environment to IIS 7.0 and assigning applications to application pools in Integrated mode. You should only add an application to an application pool in Classic mode if the application fails to work in Integrated mode. For example, your application might rely on an authentication token passed from IIS to the managed runtime, and, due to the new architecture in IIS 7.0, the process breaks your application.

Taken from: What is the difference between DefaultAppPool and Classic .NET AppPool in IIS7?

Original source: Introduction to IIS Architecture

Npm and Bower are both dependency management tools. But the main difference between both is npm is used for installing Node js modules but bower js is used for managing front end components like html, css, js etc.

A fact that makes this more confusing is that npm provides some packages which can be used in front-end development as well, like grunt and jshint.

These lines add more meaning

Bower, unlike npm, can have multiple files (e.g. .js, .css, .html, .png, .ttf) which are considered the main file(s). Bower semantically considers these main files, when packaged together, a component.

Edit: Grunt is quite different from Npm and Bower. Grunt is a javascript task runner tool. You can do a lot of things using grunt which you had to do manually otherwise. Highlighting some of the uses of Grunt:

1. Zipping some files (e.g. zipup plugin)
2. Linting on js files (jshint)
3. Compiling less files (grunt-contrib-less)

There are grunt plugins for sass compilation, uglifying your javascript, copy files/folders, minifying javascript etc.

Please Note that grunt plugin is also an npm package.

Question-1

When I want to add a package (and check in the dependency into git), where does it belong - into package.json or into bower.json

It really depends where does this package belong to. If it is a node module(like grunt,request) then it will go in package.json otherwise into bower json.

Question-2

When should I ever install packages explicitly like that without adding them to the file that manages dependencies

It does not matter whether you are installing packages explicitly or mentioning the dependency in .json file. Suppose you are in the middle of working on a node project and you need another project, say request, then you have two options:

• Edit the package.json file and add a dependency on 'request'
• npm install

OR

• Use commandline: npm install --save request

--save options adds the dependency to package.json file as well. If you don't specify --save option, it will only download the package but the json file will be unaffected.

You can do this either way, there will not be a substantial difference.

I have been searching for this for ages on my CM 11 android phone, running kitkat.

Well.. finally I found it. It's hidden in a totally unintuitive location:

1. Go to settings
2. Go to storage
3. Open the menu and choose USB computer connection

Here you can choose between Media Device (MTP), Camera (PTP) and Mass storage (UMS). Turn them all off to get it to charge only.

Sadly, if the option is not there, it is not supported by the phone. This seems to be the case for my HTC One (M7).

You almost did it. You were tricked by the fact that abs(imagem-255) will give a wrong result since your dtype is an unsigned integer. You have to do (255-imagem) in order to keep the integers unsigned:

def inverte(imagem, name):
    imagem = (255-imagem)
    cv2.imwrite(name, imagem)

You can also invert the image using the bitwise_not function of OpenCV:

imagem = cv2.bitwise_not(imagem)

If you want to parse a String to a char, whereas the String object represent more than one character, you just simply use the following expression: char c = (char) Integer.parseInt(s). Where s equals the String you want to parse. Most people forget that char's represent a 16-bit number, and thus can be a part of any numerical expression :)

            if (this.files && this.files[0]) {

                    var img = $('<img>');

This also handles case when file with invalid type ( ex. pdf ) is choosen

I had the same issue on Windows, Docker 18.06.1-ce-win73 (19507).

Removing and re-adding the shared drive via the Docker settings panel and everything worked again.

use htaccess:

#if domain has www. and not https://
  RewriteCond %{HTTPS} =off [NC]
  RewriteCond %{HTTP_HOST} ^(?i:www+\.+[^.]+\.+[^.]+)$
  RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [QSA,L,R=307]

#if domain has not www.
  RewriteCond %{HTTP_HOST} ^([^.]+\.+[^.]+)$
  RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [QSA,L,R=307]

My solution might not be the cleanest but it should work with no problems. The logic is simply to create a static variable to store your data on the Service and update your view each second on your Activity.

Let's say that you have a String on your Service that you want to send it to a TextView on your Activity. It should look like this

Your Service:

public class TestService extends Service {
    public static String myString = "";
    // Do some stuff with myString

Your Activty:

public class TestActivity extends Activity {
    TextView tv;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        tv = new TextView(this);
        setContentView(tv);
        update();
        Thread t = new Thread() {

Firstly I'd like to draw your attention to the Cocoa/CF documentation (which is always a great first port of call). The Apple docs have a section at the top of each reference article called "Companion Guides", which lists guides for the topic being documented (if any exist). For example, with NSTimer, the documentation lists two companion guides:

• Timer Programming Topics for Cocoa
• Threading Programming Guide

For your situation, the Timer Programming Topics article is likely to be the most useful, whilst threading topics are related but not the most directly related to the class being documented. If you take a look at the Timer Programming Topics article, it's divided into two parts:

• Timers
• Using Timers

For articles that take this format, there is often an overview of the class and what it's used for, and then some sample code on how to use it, in this case in the "Using Timers" section. There are sections on "Creating and Scheduling a Timer", "Stopping a Timer" and "Memory Management". From the article, creating a scheduled, non-repeating timer can be done something like this:

[NSTimer scheduledTimerWithTimeInterval:2.0
    target:self
    selector:@selector(targetMethod:)
    userInfo:nil
    repeats:NO];

This will create a timer that is fired after 2.0 seconds and calls targetMethod: on self with one argument, which is a pointer to the NSTimer instance.

If you then want to look in more detail at the method you can refer back to the docs for more information, but there is explanation around the code too.

If you want to stop a timer that is one which repeats, (or stop a non-repeating timer before it fires) then you need to keep a pointer to the NSTimer instance that was created; often this will need to be an instance variable so that you can refer to it in another method. You can then call invalidate on the NSTimer instance:

[myTimer invalidate];
myTimer = nil;

It's also good practice to nil out the instance variable (for example if your method that invalidates the timer is called more than once and the instance variable hasn't been set to nil and the NSTimer instance has been deallocated, it will throw an exception).

Note also the point on Memory Management at the bottom of the article:

Because the run loop maintains the timer, from the perspective of memory management there's typically no need to keep a reference to a timer after you’ve scheduled it. Since the timer is passed as an argument when you specify its method as a selector, you can invalidate a repeating timer when appropriate within that method. In many situations, however, you also want the option of invalidating the timer—perhaps even before it starts. In this case, you do need to keep a reference to the timer, so that you can send it an invalidate message whenever appropriate. If you create an unscheduled timer (see “Unscheduled Timers”), then you must maintain a strong reference to the timer (in a reference-counted environment, you retain it) so that it is not deallocated before you use it.

Here is a complete example

#include <thread>
#include <iostream>

class Wrapper {
   public:
      void member1() {
          std::cout << "i am member1" << std::endl;
      }
      void member2(const char *arg1, unsigned arg2) {
          std::cout << "i am member2 and my first arg is (" << arg1 << ") and second arg is (" << arg2 << ")" << std::endl;
      }
      std::thread member1Thread() {
          return std::thread([=] { member1(); });
      }
      std::thread member2Thread(const char *arg1, unsigned arg2) {
          return std::thread([=] { member2(arg1, arg2); });
      }
};
int main(int argc, char **argv) {
   Wrapper *w = new Wrapper();
   std::thread tw1 = w->member1Thread();
   std::thread tw2 = w->member2Thread("hello", 100);
   tw1.join();
   tw2.join();
   return 0;
}

Compiling with g++ produces the following result

g++ -Wall -std=c++11 hello.cc -o hello -pthread

i am member1
i am member2 and my first arg is (hello) and second arg is (100)

JAVA_HOME is an Environment Variable set to the location of the Java directory on your computer. PATH is an internal DOS command that finds the /bin directory of the version of Java that you are using. Usually they are the same, except that the PATH entry ends with /bin

Try

• which pkg-config
• if it is empty then fire
  1. brew install pkg-config
  2. OR : ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null

To change the labels for Pandas df.plot() use ax.legend([...]):

import pandas as pd
import matplotlib.pyplot as plt

fig, ax = plt.subplots()
df = pd.DataFrame({'A':26, 'B':20}, index=['N'])
df.plot(kind='bar', ax=ax)
#ax = df.plot(kind='bar') # "same" as above
ax.legend(["AAA", "BBB"]);

Another approach is to do the same by plt.legend([...]):

import matplotlib.pyplot as plt
df.plot(kind='bar')
plt.legend(["AAA", "BBB"]);

The filter option filters only the first level subkey below ansible_facts

I think it would help your comprehension if you think of connect() and listen() as counterparts, rather than connect() and bind(). The reason for this is that you can call or omit bind() before either, although it's rarely a good idea to call it before connect(), or not to call it before listen().

If it helps to think in terms of servers and clients, it is listen() which is the hallmark of the former, and connect() the latter. bind() can be found - or not found - on either.

If we assume our server and client are on different machines, it becomes easier to understand the various functions.

bind() acts locally, which is to say it binds the end of the connection on the machine on which it is called, to the requested address and assigns the requested port to you. It does that irrespective of whether that machine will be a client or a server. connect() initiates a connection to a server, which is to say it connects to the requested address and port on the server, from a client. That server will almost certainly have called bind() prior to listen(), in order for you to be able to know on which address and port to connect to it with using connect().

If you don't call bind(), a port and address will be implicitly assigned and bound on the local machine for you when you call either connect() (client) or listen() (server). However, that's a side effect of both, not their purpose. A port assigned in this manner is ephemeral.

An important point here is that the client does not need to be bound, because clients connect to servers, and so the server will know the address and port of the client even though you are using an ephemeral port, rather than binding to something specific. On the other hand, although the server could call listen() without calling bind(), in that scenario they would need to discover their assigned ephemeral port, and communicate that to any client that it wants to connect to it.

I assume as you mention connect() you're interested in TCP, but this also carries over to UDP, where not calling bind() before the first sendto() (UDP is connection-less) also causes a port and address to be implicitly assigned and bound. One function you cannot call without binding is recvfrom(), which will return an error, because without an assigned port and bound address, there is nothing to receive from (or too much, depending on how you interpret the absence of a binding).

Nested with statements will do the same job, and in my opinion, are more straightforward to deal with.

Let's say you have inFile.txt, and want to write it into two outFile's simultaneously.

with open("inFile.txt", 'r') as fr:
    with open("outFile1.txt", 'w') as fw1:
        with open("outFile2.txt", 'w') as fw2:
            for line in fr.readlines():
                fw1.writelines(line)
                fw2.writelines(line)

EDIT:

I don't understand the reason of the downvote. I tested my code before publishing my answer, and it works as desired: It writes to all of outFile's, just as the question asks. No duplicate writing or failing to write. So I am really curious to know why my answer is considered to be wrong, suboptimal or anything like that.

This is very simple in LinQ... You can use the select statement to get an Enumerable of properties of the objects.

var mySkus = myLines.Select(x => x.Sku);

Or if you want it as an Array just do...

var mySkus = myLines.Select(x => x.Sku).ToArray();

Every time you when you try to start mongod just type

sudo mongod

or if permanently want to fix this just try to give rwx premission to /data/db folder

 chmod +rwx data/

You CAN add css clases, and any type of attributes you need to blade template, try this:

{{ Form::open(array('url' => '/', 'method' => 'PUT', 'class'=>'col-md-12')) }}
.... wathever code here
{{ Form::close() }}

If you dont want to go the blade way you can add a hidden input. This is the form Laravel does, any way:

Note: Since HTML forms only support POST and GET, PUT and DELETE methods will be spoofed by automatically adding a _method hidden field to your form. (Laravel docs)

<form class="col-md-12" action="<?php echo URL::to('/');?>/post/<?=$post->postID?>" method="POST">

    <!-- Rendered blade HTML form use this hidden. Dont forget to put the form method to POST -->

    <input name="_method" type="hidden" value="PUT">

    <div class="form-group">
        <textarea type="text" class="form-control input-lg" placeholder="Text Here" name="post"><?=$post->post?></textarea>
    </div>

    <div class="form-group">
        <button class="btn btn-primary btn-lg btn-block" type="submit" value="Edit">Edit</button>
    </div>
</form>

Here is my working solution (SCSS):

.item{
  display: flex;
  justify-content: space-between;
  align-items: center;
  min-height: 120px;
  &:after{
    content:'';
    min-height:inherit;
    font-size:0;
  }
}

In short, it lets you assign values to a variable in an outer (but non-global) scope. See PEP 3104 for all the gory details.

The android Time class provides 3 formatting methods http://developer.android.com/reference/android/text/format/Time.html

This is how I did it:

/**
* This method will format the data from the android Time class (eg. myTime.setToNow())   into the format
* Date: dd.mm.yy Time: hh.mm.ss
*/
private String formatTime(String time)
{
    String fullTime= "";
    String[] sa = new String[2];

    if(time.length()>1)
    {
        Time t = new Time(Time.getCurrentTimezone());
        t.parse(time);
        // or t.setToNow();
        String formattedTime = t.format("%d.%m.%Y %H.%M.%S");
        int x = 0;

        for(String s : formattedTime.split("\\s",2))
        {   
            System.out.println("Value = " + s);
            sa[x] = s;
            x++;
        }
        fullTime = "Date: " + sa[0] + " Time: " + sa[1];
    }
    else{
        fullTime = "No time data";
    }
    return fullTime;
}

I hope thats helpful :-)

In Java you can only import class Names, or static methods/fields.

To import class use

import full.package.name.of.SomeClass;

to import static methods/fields use

import static full.package.name.of.SomeClass.staticMethod;
import static full.package.name.of.SomeClass.staticField;

The problem with DataGrip is that it puts a grip on your wallet. It is not free. Try the community edition of DBeaver at dbeaver.io. It is a FOSS multi-platform database tool for SQL programmers, DBAs and analysts that supports all popular databases: MySQL, PostgreSQL, SQLite, Oracle, DB2, SQL Server, Sybase, MS Access, Teradata, Firebird, Hive, Presto, etc.

DBeaver Community Edition makes it trivial to connect to a database, issue queries to retrieve data, and then download the result set to save it to CSV, JSON, SQL, or other common data formats. It's a viable FOSS competitor to TOAD for Postgres, TOAD for SQL Server, or Toad for Oracle.

I have no affiliation with DBeaver. I love the price and functionality, but I wish they would open up the DBeaver/Eclipse application more and made it easy to add analytics widgets to DBeaver / Eclipse, rather than requiring users to pay for the annual subscription to create graphs and charts directly within the application. My Java coding skills are rusty and I don't feel like taking weeks to relearn how to build Eclipse widgets, only to find that DBeaver has disabled the ability to add third-party widgets to the DBeaver Community Edition.

Do DBeaver users have insight as to the steps to create analytics widgets to add into the Community Edition of DBeaver?

Updated answer

Here is how to change the box model used by the input/textarea/select elements so that they all behave the same way. You need to use the box-sizing property which is implemented with a prefix for each browser

-ms-box-sizing:content-box;
-moz-box-sizing:content-box;
-webkit-box-sizing:content-box; 
box-sizing:content-box;

This means that the 2px difference we mentioned earlier does not exist..

example at http://www.jsfiddle.net/gaby/WaxTS/5/

note: On IE it works from version 8 and upwards..

Original

if you reset their borders then the select element will always be 2 pixels less than the input elements..

example: http://www.jsfiddle.net/gaby/WaxTS/2/

Use this to get an accurate count for each connection pool (assuming each user/host process uses the same connection string)

SELECT 
DB_NAME(dbid) as DBName, 
COUNT(dbid) as NumberOfConnections,
loginame as LoginName, hostname, hostprocess
FROM
sys.sysprocesses with (nolock)
WHERE 
dbid > 0
GROUP BY 
dbid, loginame, hostname, hostprocess

The file permission is okay (0777) but i think your on the shared server, so to delete your file correctly use; 1. create a correct path to your file

// delete from folder
$filename = 'test.txt';
$ifile = '/newy/made/link/uploads/'. $filename; // this is the actual path to the file you want to delete.
unlink($_SERVER['DOCUMENT_ROOT'] .$ifile); // use server document root
// your file will be removed from the folder

That small code will do the magic and remove any selected file you want from any folder provided the actual file path is collect.

For someone who needs quick reference of C# Escape Sequences that can be used in string literals:

\t     Horizontal tab (ASCII code value: 9)

\n     Line feed (ASCII code value: 10)

\r     Carriage return (ASCII code value: 13)

\'     Single quotation mark

\"     Double quotation mark

\\     Backslash

\?     Literal question mark

\x12     ASCII character in hexadecimal notation (e.g. for 0x12)

\x1234     Unicode character in hexadecimal notation (e.g. for 0x1234)

It's worth mentioning that these (in most cases) are universal codes. So \t is 9 and \n is 10 char value on Windows and Linux. But newline sequence is not universal. On Windows it's \n\r and on Linux it's just \n. That's why it's best to use Environment.Newline which gets adjusted to current OS settings. With .Net Core it gets really important.

What I do usually when I commit and push (if anyone pushed his commit this solve the problem):

git reset --hard HEAD~1

git push -f origin

We've had much better luck encrypting the jars rather than obfuscating. We use Classguard.

Getting java.nio.file.AccessDeniedException when trying to write to a folder

Unobviously, Comodo antivirus has an "Auto-Containment" setting that can cause this exact error as well. (e.g. the user can write to a location, but the java.exe and javaw.exe processes cannot).

In this edge-case scenario, adding an exception for the process and/or folder should help.

Temporarily disabling the antivirus feature will help understand if Comodo AV is the culprit.

I post this not because I use or prefer Comodo, but because it's a tremendously unobvious symptom to an otherwise functioning Java application and can cost many hours of troubleshooting file permissions that are sane and correct, but being blocked by a 3rd-party application.

While numpy arrays and pandas may be preferrable, this function imitates the behavior of zip(*args) when called as unzip(args).

Allows for generators, like the result from zip in Python 3, to be passed as args as it iterates through values.

def unzip(items, cls=list, ocls=tuple):
    """Zip function in reverse.

    :param items: Zipped-like iterable.
    :type  items: iterable

    :param cls: Container factory. Callable that returns iterable containers,
        with a callable append attribute, to store the unzipped items. Defaults
        to ``list``.
    :type  cls: callable, optional

    :param ocls: Outer container factory. Callable that returns iterable
        containers. with a callable append attribute, to store the inner
        containers (see ``cls``). Defaults to ``tuple``.
    :type  ocls: callable, optional

    :returns: Unzipped items in instances returned from ``cls``, in an instance
        returned from ``ocls``.
    """
    # iter() will return the same iterator passed to it whenever possible.
    items = iter(items)

    try:
        i = next(items)
    except StopIteration:
        return ocls()

    unzipped = ocls(cls([v]) for v in i)

    for i in items:
        for c, v in zip(unzipped, i):
            c.append(v)

    return unzipped

To use list cointainers, simply run unzip(zipped), as

unzip(zip(["a","b","c"],[1,2,3])) == (["a","b","c"],[1,2,3])

To use deques, or other any container sporting append, pass a factory function.

from collections import deque

unzip([("a",1),("b",2)], deque, list) == [deque(["a","b"]),deque([1,2])]

(Decorate cls and/or main_cls to micro manage container initialization, as briefly shown in the final assert statement above.)

The 'c' means it's a character special file.

I don't understand the issue. But here is the thing that solved my issue.

Go to Excel Options > Save > Save Files in this format > Select "Excel Workbook(*.xlsx)". Previously, my WorkBooks were opening in [Compatibuility Mode] And now they are opening in normal mode. Range function works fine with that.

Just check your php.ini file, In this file Semicolon(;) used for comment if you see then remove semicolon ;.

;extension=mysql.dll

Now your extension is enable but you need to restart appache

extension=mysql.dll

Try this:

a = 1
b = 2
int_div  = a // b

json.loads will load a json string into a python dict, json.dumps will dump a python dict to a json string, for example:

>>> json_string = '{"favorited": false, "contributors": null}'
'{"favorited": false, "contributors": null}'
>>> value = json.loads(json_string)
{u'favorited': False, u'contributors': None}
>>> json_dump = json.dumps(value)
'{"favorited": false, "contributors": null}'

So that line is incorrect since you are trying to load a python dict, and json.loads is expecting a valid json string which should have <type 'str'>.

So if you are trying to load the json, you should change what you are loading to look like the json_string above, or you should be dumping it. This is just my best guess from the given information. What is it that you are trying to accomplish?

Also you don't need to specify the u before your strings, as @Cld mentioned in the comments.

you can also use the following:

s.concat("world")

So I got this to work today. My URL is http://localhost:8888. The domain I gave facebook is localhost. I thought that it was not working because I was trying to pull data using the FB.api method. I kept on getting an "undefined" name and an image without a source, so definitely didn't have access to the Graph.

Later I realized that my problem was really that I was only passing a first argument of /me to FB.api, and I didn't have a token. So you'll need to use the FB.getLoginStatus function to get a token, which should be added to the /me argument.

map doesn't relate to a Cartesian product at all, although I imagine someone well versed in functional programming could come up with some impossible to understand way of generating a one using map.

map in Python 3 is equivalent to this:

def map(func, iterable):
    for i in iterable:
        yield func(i)

and the only difference in Python 2 is that it will build up a full list of results to return all at once instead of yielding.

Although Python convention usually prefers list comprehensions (or generator expressions) to achieve the same result as a call to map, particularly if you're using a lambda expression as the first argument:

[func(i) for i in iterable]

As an example of what you asked for in the comments on the question - "turn a string into an array", by 'array' you probably want either a tuple or a list (both of them behave a little like arrays from other languages) -

 >>> a = "hello, world"
 >>> list(a)
['h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd']
>>> tuple(a)
('h', 'e', 'l', 'l', 'o', ',', ' ', 'w', 'o', 'r', 'l', 'd')

A use of map here would be if you start with a list of strings instead of a single string - map can listify all of them individually:

>>> a = ["foo", "bar", "baz"]
>>> list(map(list, a))
[['f', 'o', 'o'], ['b', 'a', 'r'], ['b', 'a', 'z']]

Note that map(list, a) is equivalent in Python 2, but in Python 3 you need the list call if you want to do anything other than feed it into a for loop (or a processing function such as sum that only needs an iterable, and not a sequence). But also note again that a list comprehension is usually preferred:

>>> [list(b) for b in a]
[['f', 'o', 'o'], ['b', 'a', 'r'], ['b', 'a', 'z']]

You can use Dictonary to map Assume Milk,Butter,Chesse are group A (ListA) Water,Beer,Wine are group B

Dictonary<string,List<string>>) dataMap;
dataMap.add("A",ListA);
dataMap.add("B",ListB);

At View , you can foreach Keys in dataMap and process your action

This is a sample method i created to validate email addresses, if the string parameter passed is a valid email address , it returns true, else false is returned.

private boolean validateEmailAddress(String emailAddress){
    String  expression="^[\\w\\-]([\\.\\w])+[\\w]+@([\\w\\-]+\\.)+[A-Z]{2,4}$";  
       CharSequence inputStr = emailAddress;  
       Pattern pattern = Pattern.compile(expression,Pattern.CASE_INSENSITIVE);  
       Matcher matcher = pattern.matcher(inputStr);  
       return matcher.matches();
}

In order to take advantage of the auto-incrementing capability of the column, do not supply a value for that column when inserting rows. The database will supply a value for you.

Just do a simple .keys()

>>> dct = {
...     "1": "a", 
...     "3": "b", 
...     "8": {
...         "12": "c", 
...         "25": "d"
...     }
... }
>>> 
>>> dct.keys()
['1', '8', '3']
>>> for key in dct.keys(): print key
...
1
8
3
>>>

If you need a sorted list:

keylist = dct.keys()
keylist.sort()

You are logging sup directly which is a string

console.log('sup')

Also you are using the wrong id

The template says #main_search but you are using #searchBar

I suppose you are trying this out

$(function() {
   var sup = $('#main_search').val('hi')
   console.log(sup);  // sup is a variable here
});

Selenium WebDriver Java code:

Download Gecko Driver from https://github.com/mozilla/geckodriver/releases based on your platform. Extract it in a location by your choice. Write the following code:

System.setProperty("webdriver.gecko.driver", "D:/geckodriver-v0.16.1-win64/geckodriver.exe");
WebDriver driver = new FirefoxDriver();
driver.get("https://www.lynda.com/Selenium-tutorials/Mastering-Selenium-Testing-Tools/521207-2.html");

Use max():

 
Using itemgetter():

In [53]: lis=[(101, 153), (255, 827), (361, 961)]

In [81]: from operator import itemgetter

In [82]: max(lis,key=itemgetter(1))[0]    #faster solution
Out[82]: 361

using lambda:

In [54]: max(lis,key=lambda item:item[1])
Out[54]: (361, 961)

In [55]: max(lis,key=lambda item:item[1])[0]
Out[55]: 361

timeit comparison:

In [30]: %timeit max(lis,key=itemgetter(1))
1000 loops, best of 3: 232 us per loop

In [31]: %timeit max(lis,key=lambda item:item[1])
1000 loops, best of 3: 556 us per loop

Try moving ValueDate:

select sum(CASE  
             WHEN ValueDate > @startMonthDate THEN cash 
              ELSE 0 
           END) 
 from Table a
where a.branch = p.branch 
  and a.transID = p.transID

(reformatted for clarity)

You might also consider using '0' instead of NULL, as you are doing a sum. It works correctly both ways, but is maybe more indicitive of what your intentions are.

You could also group functions in one main file together with the main function looking like this:

function [varargout] = main( subfun, varargin )
[varargout{1:nargout}] = feval( subfun, varargin{:} ); 

% paste your subfunctions below ....
function str=subfun1
str='hello'

Then calling subfun1 would look like this: str=main('subfun1')

Usually this implies some Android setup issue with the project. Go to the "Resource Manager" tab where you will be able to click on "Add Android Module" and click on import gradle files. If the import fails, you will get error messages that you can work with

It's document.getElementById() and not document.getElementByID(). Check the casing for Id.

The only mistake you are doing is, you are parsing already parsed object so it's throwing error, use this and you will be good to go.

console.log(products[0].name); //name of item at 0th index

if you want to print entire json then use JSON.stringify()

This question has been asked before. Please see this question.

Using the accepted answer and adapting it to your problem you get:

SELECT tt.*
FROM myTable tt
INNER JOIN
    (SELECT ID, MAX(Date) AS MaxDateTime
    FROM myTable
    GROUP BY ID) groupedtt 
ON tt.ID = groupedtt.ID 
AND tt.Date = groupedtt.MaxDateTime

You will only see the difference if you have ties within a partition for a particular ordering value.

RANK and DENSE_RANK are deterministic in this case, all rows with the same value for both the ordering and partitioning columns will end up with an equal result, whereas ROW_NUMBER will arbitrarily (non deterministically) assign an incrementing result to the tied rows.

Example: (All rows have the same StyleID so are in the same partition and within that partition the first 3 rows are tied when ordered by ID)

WITH T(StyleID, ID)
     AS (SELECT 1,1 UNION ALL
         SELECT 1,1 UNION ALL
         SELECT 1,1 UNION ALL
         SELECT 1,2)
SELECT *,
       RANK() OVER(PARTITION BY StyleID ORDER BY ID)       AS 'RANK',
       ROW_NUMBER() OVER(PARTITION BY StyleID ORDER BY ID) AS 'ROW_NUMBER',
       DENSE_RANK() OVER(PARTITION BY StyleID ORDER BY ID) AS 'DENSE_RANK'
FROM   T  

Returns

StyleID     ID       RANK      ROW_NUMBER      DENSE_RANK
----------- -------- --------- --------------- ----------
1           1        1         1               1
1           1        1         2               1
1           1        1         3               1
1           2        4         4               2

You can see that for the three identical rows the ROW_NUMBER increments, the RANK value remains the same then it leaps to 4. DENSE_RANK also assigns the same rank to all three rows but then the next distinct value is assigned a value of 2.

So there's loads of posts on the web that show how to do this, I've found 3 ways, same as pointed out by Johan & Sjoerd. I couldn't get any of these queries to work, well obviously they work fine it's my database that's not working correctly and those queries all ran slow.

So I worked out another way that someone else may find useful:

The basic jist of it is to create a temporary table and fill it with all the information, then remove all the rows that ARE in the other table.

So I did these 3 queries, and it ran quickly (in a couple moments).

CREATE TEMPORARY TABLE

`database1`.`newRows`

SELECT

`t1`.`id` AS `columnID`

FROM

`database2`.`table` AS `t1`

.

CREATE INDEX `columnID` ON `database1`.`newRows`(`columnID`)

.

DELETE FROM `database1`.`newRows`

WHERE

EXISTS(
    SELECT `columnID` FROM `database1`.`product_details` WHERE `columnID`=`database1`.`newRows`.`columnID`
)

I too was looking for a good way to do this, I found the best way was to set a transition on the "transform" property and then change the transform and then remove the transition.

I put it all together in a jQuery plugin

https://gist.github.com/dustinpoissant/8a4837c476e3939a5b3d1a2585e8d1b0

You would use the code like this:

$("#myElement").animateTransform("rotate(180deg)", 750, function(){
  console.log("animation completed after 750ms");
});

Found Promise.prototype.catch() examples on MDN below very helpful.

(The accepted answer mentions then(null, onErrorHandler) which is basically the same as catch(onErrorHandler).)

Using and chaining the catch method

var p1 = new Promise(function(resolve, reject) {
  resolve('Success');
});

p1.then(function(value) {
  console.log(value); // "Success!"
  throw 'oh, no!';
}).catch(function(e) {
  console.log(e); // "oh, no!"
}).then(function(){
  console.log('after a catch the chain is restored');
}, function () {
  console.log('Not fired due to the catch');
});

// The following behaves the same as above
p1.then(function(value) {
  console.log(value); // "Success!"
  return Promise.reject('oh, no!');
}).catch(function(e) {
  console.log(e); // "oh, no!"
}).then(function(){
  console.log('after a catch the chain is restored');
}, function () {
  console.log('Not fired due to the catch');
});

Gotchas when throwing errors

// Throwing an error will call the catch method most of the time
var p1 = new Promise(function(resolve, reject) {
  throw 'Uh-oh!';
});

p1.catch(function(e) {
  console.log(e); // "Uh-oh!"
});

// Errors thrown inside asynchronous functions will act like uncaught errors
var p2 = new Promise(function(resolve, reject) {
  setTimeout(function() {
    throw 'Uncaught Exception!';
  }, 1000);
});

p2.catch(function(e) {
  console.log(e); // This is never called
});

// Errors thrown after resolve is called will be silenced
var p3 = new Promise(function(resolve, reject) {
  resolve();
  throw 'Silenced Exception!';
});

p3.catch(function(e) {
   console.log(e); // This is never called
});

If it is resolved

//Create a promise which would not call onReject
var p1 = Promise.resolve("calling next");

var p2 = p1.catch(function (reason) {
    //This is never called
    console.log("catch p1!");
    console.log(reason);
});

p2.then(function (value) {
    console.log("next promise's onFulfilled"); /* next promise's onFulfilled */
    console.log(value); /* calling next */
}, function (reason) {
    console.log("next promise's onRejected");
    console.log(reason);
});

(parseFloat('2.3') + parseFloat('2.4')).toFixed(1);

its going to give you solution i suppose

I've started a project to help people making their first GitHub pull request. You can do the hands-on tutorial to make your first PR here

The workflow is simple as

• Fork the repo in github
• Get clone url by clicking on clone repo button
• Go to terminal and run git clone <clone url you copied earlier>
• Make a branch for changes you're makeing git checkout -b branch-name
• Make necessary changes
• Commit your changes git commit
• Push your changes to your fork on GitHub git push origin branch-name
• Go to your fork on GitHub to see a Compare and pull request button
• Click on it and give necessary details

You can use any selector with not

p:not(:first-child){}
p:not(:first-of-type){}
p:not(:checked){}
p:not(:last-child){}
p:not(:last-of-type){}
p:not(:first-of-type){}
p:not(:nth-last-of-type(2)){}
p:not(nth-last-child(2)){}
p:not(:nth-child(2)){}

There's a far more simpler solution to tackle this.

The reason why you get ValueError: Index contains duplicate entries, cannot reshape is because, once you unstack "Location", then the remaining index columns "id" and "date" combinations are no longer unique.

You can avoid this by retaining the default index column (row #) and while setting the index using "id", "date" and "location", add it in "append" mode instead of the default overwrite mode.

So use,

e.set_index(['id', 'date', 'location'], append=True)

Once this is done, your index columns will still have the default index along with the set indexes. And unstack will work.

Let me know how it works out.

ng g component componentname

It generates the component and adds the component to module declarations.

when creating component manually , you should add the component in declaration of the module like this :

@NgModule({
  imports: [
    yourCommaSeparatedModules
    ],
  declarations: [
    yourCommaSeparatedComponents
  ]
})
export class yourModule { }

function get_dir_size($directory){
    $size = 0;
    $files = glob($directory.'/*');
    foreach($files as $path){
        is_file($path) && $size += filesize($path);
        is_dir($path)  && $size += get_dir_size($path);
    }
    return $size;
} 

Wrap your div with

<a name="sushi">
  <div id="sushi">
  </div>
</a>

and link to it by

<a href="#sushi">Sushi</a>

 ssh user@machine 'bash -s' < local_script.sh

or you can just

 ssh user@machine "remote command to run" 

Unfortunately, "shallow copy", "deep copy" and "clone" are all rather ill-defined terms.

In the Java context, we first need to make a distinction between "copying a value" and "copying an object".

int a = 1;
int b = a;     // copying a value
int[] s = new int[]{42};
int[] t = s;   // copying a value (the object reference for the array above)

StringBuffer sb = new StringBuffer("Hi mom");
               // copying an object.
StringBuffer sb2 = new StringBuffer(sb);

In short, an assignment of a reference to a variable whose type is a reference type is "copying a value" where the value is the object reference. To copy an object, something needs to use new, either explicitly or under the hood.

Now for "shallow" versus "deep" copying of objects. Shallow copying generally means copying only one level of an object, while deep copying generally means copying more than one level. The problem is in deciding what we mean by a level. Consider this:

public class Example {
    public int foo;
    public int[] bar;
    public Example() { };
    public Example(int foo, int[] bar) { this.foo = foo; this.bar = bar; };
}

Example eg1 = new Example(1, new int[]{1, 2});
Example eg2 = ... 

The normal interpretation is that a "shallow" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to the same array as in the original; e.g.

Example eg2 = new Example(eg1.foo, eg1.bar);

The normal interpretation of a "deep" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to a copy of the original array; e.g.

Example eg2 = new Example(eg1.foo, Arrays.copy(eg1.bar));

(People coming from a C / C++ background might say that a reference assignment produces a shallow copy. However, that's not what we normally mean by shallow copying in the Java context ...)

Two more questions / areas of uncertainty exist:

• How deep is deep? Does it stop at two levels? Three levels? Does it mean the whole graph of connected objects?

• What about encapsulated data types; e.g. a String? A String is actually not just one object. In fact, it is an "object" with some scalar fields, and a reference to an array of characters. However, the array of characters is completely hidden by the API. So, when we talk about copying a String, does it make sense to call it a "shallow" copy or a "deep" copy? Or should we just call it a copy?

Finally, clone. Clone is a method that exists on all classes (and arrays) that is generally thought to produce a copy of the target object. However:

• The specification of this method deliberately does not say whether this is a shallow or deep copy (assuming that is a meaningful distinction).

• In fact, the specification does not even specifically state that clone produces a new object.

Here's what the javadoc says:

"Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression x.clone() != x will be true, and that the expression x.clone().getClass() == x.getClass() will be true, but these are not absolute requirements. While it is typically the case that x.clone().equals(x) will be true, this is not an absolute requirement."

Note, that this is saying that at one extreme the clone might be the target object, and at the other extreme the clone might not equal the original. And this assumes that clone is even supported.

In short, clone potentially means something different for every Java class.

Some people argue (as @supercat does in comments) that the Java clone() method is broken. But I think the correct conclusion is that the concept of clone is broken in the context of OO. AFAIK, it is impossible to develop a unified model of cloning that is consistent and usable across all object types.

A slightly modified version of Tim Downs answer. However, since Tim rolled back my edit, I've to answer this myself. My solution makes it possible to use extra arguments as third (3, 4, 5...) parameter and to clear the timer:

function Timer(callback, delay) {
    var args = arguments,
        self = this,
        timer, start;

    this.clear = function () {
        clearTimeout(timer);
    };

    this.pause = function () {
        this.clear();
        delay -= new Date() - start;
    };

    this.resume = function () {
        start = new Date();
        timer = setTimeout(function () {
            callback.apply(self, Array.prototype.slice.call(args, 2, args.length));
        }, delay);
    };

    this.resume();
}

As Tim mentioned, extra parameters are not available in IE lt 9, however I worked a bit around so that it will work in oldIE's too.

Usage: new Timer(Function, Number, arg1, arg2, arg3...)

function callback(foo, bar) {
    console.log(foo); // "foo"
    console.log(bar); // "bar"
}

var timer = new Timer(callback, 1000, "foo", "bar");

timer.pause();
document.onclick = timer.resume;

To make the solution by @flion look really great, you could adjust the center point for that icon so it doesn't wobble up and down. This looks right for me at a small font size:

.glyphicon-refresh.spinning {
  transform-origin: 48% 50%;
}

You might also look to dotenv which follows the tenets of a twelve-factor app.

I used to use node-config, but created dotenv for that reason. It was completely inspired by ruby's dotenv library.

Usage is quite easy:

var dotenv = require('dotenv');
dotenv.load();

Then you just create a .env file and put your settings in there like so:

S3_BUCKET=YOURS3BUCKET
SECRET_KEY=YOURSECRETKEYGOESHERE
OTHER_SECRET_STUFF=my_cats_middle_name

That's dotenv for nodejs.

You could use a combination of SUBSTR and INSTR as follows :

Example string : field = 'DE124028#@$1048708#@$000#@$536967136#@$'

The seperator being #@$.

To get the '1048708' for example :

If the field is of fixed length ( 7 here ) :

substr(field,instr(field,'#@$',1,1)+3,7)

If the field is of variable length :

substr(field,instr(field,'#@$',1,1)+3,instr(field,'#@$',1,2) - (instr(field,'#@$',1,1)+3)) 

You should probably look into SUBSTR and INSTR functions for more flexibility.

The enumerate function works as follows:

doc = """I like movie. But I don't like the cast. The story is very nice"""
doc1 = doc.split('.')
for i in enumerate(doc1):
     print(i)

The output is

(0, 'I like movie')
(1, " But I don't like the cast")
(2, ' The story is very nice')

I had to disable selinux to make this work. Note. The system needs to be rebooted for selinux to take effect.

If you are using Forms you can use the icon setting in the properties pane. To do this select the form and scroll down in the properties pane till you see the icon setting. When you open the application it will have the icon wherever you have it in your application and in the task bar

Seeing as I stumbled upon this from Google while trying to solve the very same problem, I'm just gonna throw in the solution I cooked up in case someone finds it useful.

From my point of view there's really only 1 solutions to this problem -- @PrePersist. If you do it in @PrePersist, you gotta check if the value's been set already though.

Suppose there are multiple static synchronized methods (m1, m2, m3, m4) in a class, and suppose one thread is accessing m1, then no other thread at the same time can access any other static synchronized methods.

I tried all of stack overflow and all didn't works. But this works for me:

1. Open System Configuration
2. Click Service tab
3. Uncheck all of Hyper-V related

java.time

The java.time framework built into Java 8 and later supplants both the old date-time classes bundled with the earliest versions of Java and the Joda-Time library. The java.time classes have been back-ported to Java 6 & 7 and to Android.

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds.

Instant instant = Instant.now();

Apply an offset-from-UTC (a number of hours and possible minutes and seconds) to get an OffsetDateTime.

ZoneOffset offset = ZoneOffset.of( "-04:00" );
OffsetDateTime odt = OffsetDateTime.ofInstant( instant , offset );

Better yet is applying a full time zone which is an offset plus a set of rules for handling anomalies such as Daylight Saving Time (DST).

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

Database

Hopefully the JDBC drivers will be updated to work directly with the java.time classes. Until then we must use the java.sql classes to move date-time values to/from the database. But limit your use of the java.sql classes to the chore of database transit. Do not use them for business logic. As part of the old date-time classes they are poorly designed, confusing, and troublesome.

Use new methods added to the old classes to convert to/from java.time. Look for to… and valueOf methods.

Use the java.sql.Timestamp class for date-time values.

java.sql.Timestamp ts = java.sql.Timestamp.valueOf( instant );

And going the other direction…

Instant instant = ts.toInstant();

For date-time data you virtually always want the TIMESTAMP WITH TIME ZONE data type rather than WITHOUT when designing your table columns in your database.

Possibly some mileage with this approach. This seems to get the date back to a session variable. The string it returns displays the javascript date but when I try to manipulate the string it displays the javascript code.

ob_start();
?>
<script type="text/javascript">
    var d = new Date();
    document.write(d);
</script>
<?
$_SESSION["date"]  = ob_get_contents();
ob_end_clean();
echo $_SESSION["date"]; // displays the date
echo substr($_SESSION["date"],28); 
// displays 'script"> var d = new Date(); document.write(d);'

You can generate a set of colors like this:

myCol = c("pink1", "violet", "mediumpurple1", "slateblue1", "purple", "purple3",
          "turquoise2", "skyblue", "steelblue", "blue2", "navyblue",
          "orange", "tomato", "coral2", "palevioletred", "violetred", "red2",
          "springgreen2", "yellowgreen", "palegreen4",
          "wheat2", "tan", "tan2", "tan3", "brown",
          "grey70", "grey50", "grey30")

These colors are as distinct as possible. For those similar colors, they form a gradient so that you can easily tell the differences between them.

Try something like this:

IWebDriver _driver = new FirefoxDriver();
_driver.Manage().Window.Position = new Point(0, 0);
_driver.Manage().Window.Size = new Size(1024, 768);

Not sure if it'll resize after being launched though, so maybe it's not what you want

Android has all the tools you need to parse json built-in. Example follows, no need for GSON or anything like that.

Get your JSON:

Assume you have a json string

String result = "{\"someKey\":\"someValue\"}";

Create a JSONObject:

JSONObject jObject = new JSONObject(result);

If your json string is an array, e.g.:

String result = "[{\"someKey\":\"someValue\"}]"

then you should use JSONArray as demonstrated below and not JSONObject

To get a specific string

String aJsonString = jObject.getString("STRINGNAME");

To get a specific boolean

boolean aJsonBoolean = jObject.getBoolean("BOOLEANNAME");

To get a specific integer

int aJsonInteger = jObject.getInt("INTEGERNAME");

To get a specific long

long aJsonLong = jObject.getLong("LONGNAME");

To get a specific double

double aJsonDouble = jObject.getDouble("DOUBLENAME");

To get a specific JSONArray:

JSONArray jArray = jObject.getJSONArray("ARRAYNAME");

To get the items from the array

for (int i=0; i < jArray.length(); i++)
{
    try {
        JSONObject oneObject = jArray.getJSONObject(i);
        // Pulling items from the array
        String oneObjectsItem = oneObject.getString("STRINGNAMEinTHEarray");
        String oneObjectsItem2 = oneObject.getString("anotherSTRINGNAMEINtheARRAY");
    } catch (JSONException e) {
        // Oops
    }
}

Console outputs to the console window and Winforms applications do not show the console window. You should be able to use System.Diagnostics.Debug.WriteLine to send output to the output window in your IDE.

Edit: In regards to the problem, have you verified your mainForm_Load is actually being called? You could place a breakpoint at the beginning of mainForm_Load to see. If it is not being called, I suspect that mainForm_Load is not hooked up to the Load event.

Also, it is more efficient and generally better to override On{EventName} instead of subscribing to {EventName} from within derived classes (in your case overriding OnLoad instead of Load).

I tried all the above solution, but didn't worked for me. Finally was able to resolve it with a simple fix.

on STS, Run Configuration > open your Spring Boot App > Open your configuration, Follow the steps,

1. In Spring boot Tab, check your Main class and profile.
2. Then go to classpath tab, In the bottom you will see two checkboxes,one is "Exclude Test Code"(Check this if you do not want to run test classes) and other, "Use Temporary Jar file to specify classpath" (this is necessary).

Save your configuration and run.

You don't need to use arrays.

JSON values can be arrays, objects, or primitives (numbers or strings).

You can write JSON like this:

{ 
    "stuff": {
        "onetype": [
            {"id":1,"name":"John Doe"},
            {"id":2,"name":"Don Joeh"}
        ],
        "othertype": {"id":2,"company":"ACME"}
    }, 
    "otherstuff": {
        "thing": [[1,42],[2,2]]
     }
}

You can use it like this:

obj.stuff.onetype[0].id
obj.stuff.othertype.id
obj.otherstuff.thing[0][1]  //thing is a nested array or a 2-by-2 matrix.
                            //I'm not sure whether you intended to do that.

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("param1","value1");

String query = URLEncodedUtils.format(params, "utf-8");

URI url = URIUtils.createURI(scheme, userInfo, authority, port, path, query, fragment); //can be null
HttpGet httpGet = new HttpGet(url);

URI javadoc

Note: url = new URI(...) is buggy

And yet another option: https://github.com/apptik/jus

• It is modular like Volley, but more extended and documentation is improving, supporting different HTTP stacks and converters out of the box
• It has a module to generate server API interface mappings like Retrofit
• It also has JavaRx support

And many other handy features like markers, transformers, etc.

A complete example using schedule and multiprocessing, with on and off control and parameter to run_job() the return codes are simplified and interval is set to 10sec, change to every(2).hour.do()for 2hours. Schedule is quite impressive it does not drift and I've never seen it more than 100ms off when scheduling. Using multiprocessing instead of threading because it has a termination method.

#!/usr/bin/env python3

import schedule
import time
import datetime
import uuid

from flask import Flask, request
from multiprocessing import Process

app = Flask(__name__)
t = None
job_timer = None

def run_job(id):
    """ sample job with parameter """
    global job_timer
    print("timer job id={}".format(id))
    print("timer: {:.4f}sec".format(time.time() - job_timer))
    job_timer = time.time()

def run_schedule():
    """ infinite loop for schedule """
    global job_timer
    job_timer = time.time()
    while 1:
        schedule.run_pending()
        time.sleep(1)

@app.route('/timer/<string:status>')
def mytimer(status, nsec=10):
    global t, job_timer
    if status=='on' and not t:
        schedule.every(nsec).seconds.do(run_job, str(uuid.uuid4()))
        t = Process(target=run_schedule)
        t.start()
        return "timer on with interval:{}sec\n".format(nsec)
    elif status=='off' and t:
        if t:
            t.terminate()
            t = None
            schedule.clear()
        return "timer off\n"
    return "timer status not changed\n"

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=5000)

You test this by just issuing:

$ curl http://127.0.0.1:5000/timer/on
timer on with interval:10sec
$ curl http://127.0.0.1:5000/timer/on
timer status not changed
$ curl http://127.0.0.1:5000/timer/off
timer off
$ curl http://127.0.0.1:5000/timer/off
timer status not changed

Every 10sec the timer is on it will issue a timer message to console:

127.0.0.1 - - [18/Sep/2018 21:20:14] "GET /timer/on HTTP/1.1" 200 -
timer job id=b64ed165-911f-4b47-beed-0d023ead0a33
timer: 10.0117sec
timer job id=b64ed165-911f-4b47-beed-0d023ead0a33
timer: 10.0102sec

The OP needed to cast as string outside the {% set ... %}. But if that not your case you can do:

{% set curYear = 2013 | string() %}

Note that you need the parenthesis on that jinja filter.

If you're concatenating 2 variables, you can also use the ~ custom operator.

Get document size without jQuery

document.documentElement.clientWidth
document.documentElement.clientHeight

And use this if you need Screen size

screen.width
screen.height

A closure is a block of code that can be referenced (and passed around) with access to the variables of the enclosing scope.

Since Java 1.1, anonymous inner class have provided this facility in a highly verbose manner. They also have a restriction of only being able to use final (and definitely assigned) local variables. (Note, even non-final local variables are in scope, but cannot be used.)

Java SE 8 is intended to have a more concise version of this for single-method interfaces*, called "lambdas". Lambdas have much the same restrictions as anonymous inner classes, although some details vary randomly.

Lambdas are being developed under Project Lambda and JSR 335.

*Originally the design was more flexible allowing Single Abstract Methods (SAM) types. Unfortunately the new design is less flexible, but does attempt to justify allowing implementation within interfaces.

This error happens when you have a __unicode__ method that is a returning a field that is not entered. Any blank field is None and Python cannot convert None, so you get the error.

In your case, the problem most likely is with the PCE model's __unicode__ method, specifically the field its returning.

You can prevent this by returning a default value:

def __unicode__(self):
   return self.some_field or u'None'

From the Python glossary:

An object is hashable if it has a hash value which never changes during its lifetime (it needs a __hash__() method), and can be compared to other objects (it needs an __eq__() or __cmp__() method). Hashable objects which compare equal must have the same hash value.

Hashability makes an object usable as a dictionary key and a set member, because these data structures use the hash value internally.

All of Python’s immutable built-in objects are hashable, while no mutable containers (such as lists or dictionaries) are. Objects which are instances of user-defined classes are hashable by default; they all compare unequal, and their hash value is their id().

For a similar effect to form's target attribute, you can also use the formtarget attribute of input[type="submit]" or button[type="submit"].

From MDN:

...this attribute is a name or keyword indicating where to display the response that is received after submitting the form. This is a name of, or keyword for, a browsing context (for example, tab, window, or inline frame). If this attribute is specified, it overrides the target attribute of the elements's form owner. The following keywords have special meanings:

• _self: Load the response into the same browsing context as the current one. This value is the default if the attribute is not specified.
• _blank: Load the response into a new unnamed browsing context.
• _parent: Load the response into the parent browsing context of the current one. If there is no parent, this option behaves the same way as _self.
• _top: Load the response into the top-level browsing context (that is, the browsing context that is an ancestor of the current one, and has no parent). If there is no parent, this option behaves the same way as _self.

Your loop will run only for count/2 times. So it will not print the whole array.

Also, temp=ar[i] should be used instead of ar[i]=temp as value of ar[i] is not getting stored anywhere in the latter statement, hence it is getting destroyed.

For applications such as games and embedded systems where memory and performance are both critical, float is usually the numeric type of choice as it is faster and half the size of a double. Integers used to be the weapon of choice, but floating point performance has overtaken integer in modern processors. Decimal is right out!
