If you want one row for each filename, reflecting a specific states and listing the most recent date then this is your friend:

select filename ,
       status   ,
       max_date = max( dates )
from some_table t
group by filename , status
having status = '<your-desired-status-here>'

Easy!

Simple explanation: Parsing is breaking a block of data into smaller pieces (tokens) by following a set of rules (using delimiters for example), so that this data could be processes piece by piece (managed, analysed, interpreted, transmitted, ets).

Examples: Many applications (like Spreadsheet programs) use CSV (Comma Separated Values) file format to import and export data. CSV format makes it possible for the applications to process this data with a help of a special parser. Web browsers have special parsers for HTML and CSS files. JSON parsers exist. All special file formats must have some parsers designed specifically for them.

As the accepted answer suggests you can add "using" to all views by adding to section of config file.

But for a single view you could just use

@using SomeNamespace.Extensions

Those are zero-length strings, not null. But if you want to remove them:

firstArray[0] refers to the first element
firstArray[1] refers to the second element

You can move the second into the first thusly:

firstArray[0]  = firstArray[1]

If you were to do this for elements [1,2], then [2,3], etc. you would eventually shift the entire contents of the array to the left, eliminating element 0. Can you see how that would apply?

If you haven't install mysql_client yet and using Docker container instead:

sudo docker exec MySQL_CONTAINER_NAME /usr/bin/mysqldump --host=192.168.1.1 -u username --password=password db_name > dump.sql

That is because is does not exist, since it is bounded to Windows.

Use the standard functions from <stdio.h> instead, such as getc

The suggested ncurses library is good if you want to write console-based GUIs, but I don't think it is what you want.

This is due to your mysql configuration. According to this error you are trying to connect with the user 'root' to the database host 'localhost' on a database namend 'sgce' without being granted access rights.

Presuming you did not configure your mysql instance. Log in as root user and to the folloing:

CREATE DATABASE sgce;

CREATE USER 'root'@'localhost' IDENTIFIED BY 'mikem';
GRANT ALL PRIVILEGES ON sgce. * TO 'root'@'localhost';
FLUSH PRIVILEGES;

Also add your database_port in the parameters.yml. By default mysql listens on 3306:

database_port: 3306

SQL is a declarative language, not a procedural language. That is, you construct a SQL statement to describe the results that you want. You are not telling the SQL engine how to do the work.

As a general rule, it is a good idea to let the SQL engine and SQL optimizer find the best query plan. There are many person-years of effort that go into developing a SQL engine, so let the engineers do what they know how to do.

Of course, there are situations where the query plan is not optimal. Then you want to use query hints, restructure the query, update statistics, use temporary tables, add indexes, and so on to get better performance.

As for your question. The performance of CTEs and subqueries should, in theory, be the same since both provide the same information to the query optimizer. One difference is that a CTE used more than once could be easily identified and calculated once. The results could then be stored and read multiple times. Unfortunately, SQL Server does not seem to take advantage of this basic optimization method (you might call this common subquery elimination).

Temporary tables are a different matter, because you are providing more guidance on how the query should be run. One major difference is that the optimizer can use statistics from the temporary table to establish its query plan. This can result in performance gains. Also, if you have a complicated CTE (subquery) that is used more than once, then storing it in a temporary table will often give a performance boost. The query is executed only once.

The answer to your question is that you need to play around to get the performance you expect, particularly for complex queries that are run on a regular basis. In an ideal world, the query optimizer would find the perfect execution path. Although it often does, you may be able to find a way to get better performance.

I do get the same information while debugging. Though not while I am checking the stacktrace. Most probably you would have used the optimization flag I think. Check this link - something related.

Try compiling with -g3 remove any optimization flag. Then it might work. HTH!

I've done this kind of thing with a form that contains a TextBox.

So if you wanted to put this in say cell H1, then use:

ActiveSheet.Range("H1").Value = txtBoxName.Text

Check out the link given it has Apache HTTP Server 2.4.2 x86 and x64 Windows Installers http://www.anindya.com/apache-http-server-2-4-2-x86-and-x64-windows-installers/

You can use PowerShell to run b.bat as administrator from a.bat:

set mydir=%~dp0

Powershell -Command "& { Start-Process \"%mydir%b.bat\" -verb RunAs}"

It will prompt the user with a confirmation dialog. The user chooses YES, and then b.bat will be run as administrator.

Send the data from the form:

$("#change_section_type").live "change", ->
url = $(this).attr("data-url")
postData = $(this).parents("#contract_setting_form").serializeArray()
$.ajax
  type: "PUT"
  url: url
  dataType: "script"
  data: postData

Besides grep, you can also use other utilities such as awk or sed

Here is a few examples. Let say you want to search for a string is in the file named GPL.

Your sample file

user@linux:~$ cat -n GPL 
     1    The GNU General Public License is a free, copyleft license for
     2    The licenses for most software and other practical works are designed
     3  the GNU General Public License is intended to guarantee your freedom to
     4  GNU General Public License for most of our software;
user@linux:~$ 

1. grep

user@linux:~$ grep is GPL 
  The GNU General Public License is a free, copyleft license for
the GNU General Public License is intended to guarantee your freedom to
user@linux:~$ 

2. awk

user@linux:~$ awk /is/ GPL 
  The GNU General Public License is a free, copyleft license for

3. sed

user@linux:~$ sed -n '/is/p' GPL
  The GNU General Public License is a free, copyleft license for

Hope this helps

Easiest way to do this is close the project. Using file explorer head to the location of that project and delete.

Alot of processes, even simply deleting can be annoying to figure out in studio. Most deleting options a good work around is to delete using file explorer. This is a part of the process tht works for deleting modules as well. Which u will prob find is painful as well

Routes

export const MyRoutes: Routes = [
    { path: '/items/:id', component: MyComponent }
]

Component

import { ActivatedRoute } from '@angular/router';
public id: string;

constructor(private route: ActivatedRoute) {}

ngOnInit() {
   this.id = this.route.snapshot.paramMap.get('id');
}

for me that issue happened because i generated .jks file on my laptop with 1.8.0_251 and i copied it on server witch had java 1.8.0_45 and when I used that .jks file in my code i got java.io.IOException: Invalid Keystore format.

to solve this issue i generated .jks file directly on the server instead of copy there from my laptop which had different java version.

Floating point numbers in C use IEEE 754 encoding.

This type of encoding uses a sign, a significand, and an exponent.

Because of this encoding, many numbers will have small changes to allow them to be stored.

Also, the number of significant digits can change slightly since it is a binary representation, not a decimal one.

Single precision (float) gives you 23 bits of significand, 8 bits of exponent, and 1 sign bit.

Double precision (double) gives you 52 bits of significand, 11 bits of exponent, and 1 sign bit.

As others have mentioned, Dart's is operator is the equivalent of Javascript's instanceof operator. However, I haven't found a direct analogue of the typeof operator in Dart.

Thankfully the dart:mirrors reflection API has recently been added to the SDK, and is now available for download in the latest Editor+SDK package. Here's a short demo:

import 'dart:mirrors'; 

getTypeName(dynamic obj) {
  return reflect(obj).type.reflectedType.toString();
}

void main() {
  var val = "\"Dart is dynamically typed (with optional type annotations.)\"";
  if (val is String) {
    print("The value is a String, but I needed "
        "to check with an explicit condition.");
  }
  var typeName = getTypeName(val);
  print("\nThe mirrored type of the value is $typeName.");
}

I know this is an old question, but I wanted to make an answer of my own. here is another way to do this if you "really" want to add to the end of the list instead of using list.add(str) you can do it this way, but I don't recommend.

 String[] items = new String[]{"Hello", "World"};
        ArrayList<String> list = new ArrayList<>();
        Collections.addAll(list, items);
        int endOfList = list.size();
        list.add(endOfList, "This goes end of list");
        System.out.println(Collections.singletonList(list));

this is the 'Compact' way of adding the item to the end of list. here is a safer way to do this, with null checking and more.

String[] items = new String[]{"Hello", "World"};
        ArrayList<String> list = new ArrayList<>();
        Collections.addAll(list, items);
        addEndOfList(list, "Safer way");
        System.out.println(Collections.singletonList(list));

 private static void addEndOfList(List<String> list, String item){
            try{
                list.add(getEndOfList(list), item);
            } catch (IndexOutOfBoundsException e){
                System.out.println(e.toString());
            }
        }

   private static int getEndOfList(List<String> list){
        if(list != null) {
            return list.size();
        }
        return -1;
    }

Heres another way to add items to the end of list, happy coding :)

I had my files at the correct places, and just removing <scope>test</scope> from the JUnit dependency entry solved the problem (I am using JUnit 4.12). I believe that with the test scope the dependency was just being ignored during the compilation phase. Now everything is working even when I call mvn test.

No need to activate or selection sheets or cells if you're using VBA. You can access it all directly. The code:

Dim rng As Range
For Each rng In Sheets("Feuil2").Range("A1:A333")
    Sheets("Classeur2.csv").Cells(rng.Value, rng.Offset(, 1).Value) = "1"
Next rng

is producing the same result as Joe's code.

If you need to switch sheets for some reasons, use Application.ScreenUpdating = False at the beginning of your macro (and Application.ScreenUpdating=True at the end). This will remove the screenflickering - and speed up the execution.

Uninstall composer

To remove just composer package itself from Ubuntu 16.04 (Xenial Xerus) execute on terminal:

sudo apt-get remove composer

Uninstall composer and it's dependent packages

To remove the composer package and any other dependant package which are no longer needed from Ubuntu Xenial.

sudo apt-get remove --auto-remove composer

Purging composer

If you also want to delete configuration and/or data files of composer from Ubuntu Xenial then this will work:

sudo apt-get purge composer

To delete configuration and/or data files of composer and it's dependencies from Ubuntu Xenial then execute:

sudo apt-get purge --auto-remove composer

https://www.howtoinstall.co/en/ubuntu/xenial/composer?action=remove

I think that the best way to do this is:

Stash your local changes:

git stash

Update the branch to the latest code

git pull

Merge your local changes into the latest code:

git stash apply

Add, commit and push your changes

git add
git commit
git push

In my experience this is the path to least resistance with Git (on the command line anyway).

Usage: mysqldump [OPTIONS] database [tables]

i.e.

mysqldump -u username -p db_name table1_name table2_name table3_name > dump.sql

I know you've found another solution, but for those like me who find this question, looking for the same thing, it can be achieved with requests as follows:

Firstly, as Marcus did, check the source of the login form to get three pieces of information - the url that the form posts to, and the name attributes of the username and password fields. In his example, they are inUserName and inUserPass.

Once you've got that, you can use a requests.Session() instance to make a post request to the login url with your login details as a payload. Making requests from a session instance is essentially the same as using requests normally, it simply adds persistence, allowing you to store and use cookies etc.

Assuming your login attempt was successful, you can simply use the session instance to make further requests to the site. The cookie that identifies you will be used to authorise the requests.

Example

import requests

# Fill in your details here to be posted to the login form.
payload = {
    'inUserName': 'username',
    'inUserPass': 'password'
}

# Use 'with' to ensure the session context is closed after use.
with requests.Session() as s:
    p = s.post('LOGIN_URL', data=payload)
    # print the html returned or something more intelligent to see if it's a successful login page.
    print p.text

    # An authorised request.
    r = s.get('A protected web page url')
    print r.text
        # etc...

As of iOS 9.0 there's no way to get the orientation reliably. This is the code I used for an app I design for only portrait mode, so if the app is opened in landscape mode it will still be accurate:

screenHeight = [[UIScreen mainScreen] bounds].size.height;
screenWidth = [[UIScreen mainScreen] bounds].size.width;
if (screenWidth > screenHeight) {
    float tempHeight = screenWidth;
    screenWidth = screenHeight;
    screenHeight = tempHeight;
}

You can use xp_dirtree

It takes three parameters:

Path of a Root Directory, Depth up to which you want to get files and folders and the last one is for showing folders only or both folders and files.

EXAMPLE: EXEC xp_dirtree 'C:\', 2, 1

It was changed between 3.1 and 3.2:

This is a terse description of the new features added to bash-3.2 since the release of bash-3.1.

Quoting the string argument to the [[ command's =~ operator now forces string matching, as with the other pattern-matching operators.

So use it without the quotes thus:

i="test"
if [[ $i =~ 200[78] ]] ; then
    echo "OK"
else
    echo "not OK"
fi

I prefer to use mutex mechanism in such cases, but if you really want to use boolean, then you should declare it as volatile (to provide the change visibility across threads) and just run the body-less cycle with that boolean as a condition :

//.....some class

volatile boolean someBoolean; 

Thread someThread = new Thread() {

    @Override 
    public void run() {
        //some actions
        while (!someBoolean); //wait for condition 
        //some actions 
    }

};

You must instruct your logger not to send its messages on up to its parent logger:

...
import java.util.logging.*;
...
Logger logger = Logger.getLogger(this.getClass().getName());
logger.setUseParentHandlers(false);
...

However, this should be done before adding any more handlers to logger.

For those who are still getting blank response with $request->getContent(), you can use:

$request->all()

e.g:

public function foo(Request $request){
   $bodyContent = $request->all();
}

Yes, that is normal behavior. You basically read to the end of the file the first time (you can sort of picture it as reading a tape), so you can't read any more from it unless you reset it, by either using f.seek(0) to reposition to the start of the file, or to close it and then open it again which will start from the beginning of the file.

If you prefer you can use the with syntax instead which will automatically close the file for you.

e.g.,

with open('baby1990.html', 'rU') as f:
  for line in f:
     print line

once this block is finished executing, the file is automatically closed for you, so you could execute this block repeatedly without explicitly closing the file yourself and read the file this way over again.

Also, Given a DataFrame

data

as in your example, if you would like to extract column a and d only (e.i. the 1st and the 4th column), iloc mothod from the pandas dataframe is what you need and could be used very effectively. All you need to know is the index of the columns you would like to extract. For example:

>>> data.iloc[:,[0,3]]

will give you

          a         d
0  0.883283  0.100975
1  0.614313  0.221731
2  0.438963  0.224361
3  0.466078  0.703347
4  0.955285  0.114033
5  0.268443  0.416996
6  0.613241  0.327548
7  0.370784  0.359159
8  0.692708  0.659410
9  0.806624  0.875476

Simply you can add that way. see below the console image

I encountered this problem as well, but it is not quite the same, so just FYI. Recent upgrades causes this error message due to this decorator syntax.

ERROR/MainProcess] Received unregistered task of type 'my_server_check'.

@task('my_server_check')

Had to be change to just

@task()

No clue why.

I'd start with something like this (and if there is something wrong with my code, I'd of course appreciate any comment):

public class ItemsList extends ListActivity {

private ItemsAdapter adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.items_list);

    this.adapter = new ItemsAdapter(this, R.layout.items_list_item, ItemManager.getLoadedItems());
    setListAdapter(this.adapter);
}

private class ItemsAdapter extends ArrayAdapter<Item> {

    private Item[] items;

    public ItemsAdapter(Context context, int textViewResourceId, Item[] items) {
        super(context, textViewResourceId, items);
        this.items = items;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View v = convertView;
        if (v == null) {
            LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            v = vi.inflate(R.layout.items_list_item, null);
        }

        Item it = items[position];
        if (it != null) {
            ImageView iv = (ImageView) v.findViewById(R.id.list_item_image);
            if (iv != null) {
                iv.setImageDrawable(it.getImage());
            }
        }

        return v;
    }
}

@Override
protected void onListItemClick(ListView l, View v, int position, long id) {
    this.adapter.getItem(position).click(this.getApplicationContext());
}
}

E.g. extending ArrayAdapter with own type of Items (holding information about your pictures) and overriden getView() method, that prepares view for items within list. There is also method add() on ArrayAdapter to add items to the end of the list.

R.layout.items_list is simple layout with ListView

R.layout.items_list_item is layout representing one item in list

request.args is a MultiDict with the parsed contents of the query string. From the documentation of get method:

get(key, default=None, type=None)

Return the default value if the requested data doesn’t exist. If type is provided and is a callable it should convert the value, return it or raise a ValueError if that is not possible.

You could also try this function. Can't remember the original author, but all credits goes to him/her.

You can't manipulate :after, because it's not technically part of the DOM and therefore is inaccessible by any JavaScript. But you can add a new class with a new :after specified.

CSS:

.pageMenu .active.changed:after { 
/* this selector is more specific, so it takes precedence over the other :after */
    border-top-width: 22px;
    border-left-width: 22px;
    border-right-width: 22px;
}

JS:

$('.pageMenu .active').toggleClass('changed');

UPDATE: while it's impossible to directly modify the :after content, there are ways to read and/or override it using JavaScript. See "Manipulating CSS pseudo-elements using jQuery (e.g. :before and :after)" for a comprehensive list of techniques.

Based on this code (which you provided in response to Alex's answer):

Editable newTxt=(Editable)userName1.getText(); 
String newString = newTxt.toString();

It looks like you're trying to get the text out of a TextView or EditText. If that's the case then this should work:

String newString = userName1.getText().toString();

You need to change from queue import Queue to from multiprocessing import Queue.

The root reason is the former Queue is designed for threading module Queue while the latter is for multiprocessing.Process module.

For details, you can read some source code or contact me!

Short answer: it's closely related to the Content-Security-Policy: upgrade-insecure-requests response header, indicating that the browser supports it (and in fact prefers it).

It took me 30mins of Googling, but I finally found it buried in the W3 spec.

The confusion comes because the header in the spec was HTTPS: 1, and this is how Chromium implemented it, but after this broke lots of websites that were poorly coded (particularly WordPress and WooCommerce) the Chromium team apologized:

"I apologize for the breakage; I apparently underestimated the impact based on the feedback during dev and beta."
— Mike West, in Chrome Issue 501842

Their fix was to rename it to Upgrade-Insecure-Requests: 1, and the spec has since been updated to match.

Anyway, here is the explanation from the W3 spec (as it appeared at the time)...

The HTTPS HTTP request header field sends a signal to the server expressing the client’s preference for an encrypted and authenticated response, and that it can successfully handle the upgrade-insecure-requests directive in order to make that preference as seamless as possible to provide.

...

When a server encounters this preference in an HTTP request’s headers, it SHOULD redirect the user to a potentially secure representation of the resource being requested.

When a server encounters this preference in an HTTPS request’s headers, it SHOULD include a Strict-Transport-Security header in the response if the request’s host is HSTS-safe or conditionally HSTS-safe [RFC6797].

function TellFirstCharacterType(inputString){
    var firstCharacter = inputString[0];
    if(isNaN(firstCharacter)){
        if(firstCharacter == firstCharacter.toUpperCase()){
            return "It's a uppercase character";
        }
        else{
            return "It's a lowercase character";
        }
    }
    else{
        return "It's a Number";
    }
}

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}

So you can use:

myvar = getURLParameter('myvar');

In Symfony 2.6 and older versions, to get a parameter in a controller - you should get the container first, and then - the needed parameter.

$this->container->getParameter('api_user');

This documentation chapter explains it.

While $this->get() method in a controller will load a service (doc)

In Symfony 2.7 and newer versions, to get a parameter in a controller you can use the following:

$this->getParameter('api_user');

function EnableHyperLink(id) {
        $('#' + id).attr('onclick', 'Pagination("' + id + '")');//onclick event which u 
        $('#' + id).addClass('enable-link');
        $('#' + id).removeClass('disable-link');
    }

    function DisableHyperLink(id) {
        $('#' + id).addClass('disable-link');
        $('#' + id).removeClass('enable-link');
        $('#' + id).removeAttr('onclick');
    }

.disable-link
{
    text-decoration: none !important;
    color: black !important;
    cursor: default;
}
.enable-link
{
    text-decoration: underline !important;
    color: #075798 !important;
    cursor: pointer !important;
}

Its faster with MUTT command

3. -y to send the mail

Use the length property or the size method to find out how many items are in a jQuery collection. Use the descendant selector to select all <option>'s within a <select>.

HTML:

<select id="myDropDown">
<option>1</option>
<option>2</option>
.
.
.
</select>

JQuery:

var numberOfOptions = $('select#myDropDown option').length

And a quick note, often you will need to do something in jquery for a very specific thing, but you first need to see if the very specific thing exists. The length property is the perfect tool. example:

   if($('#myDropDown option').length > 0{
      //do your stuff..
    } 

This 'translates' to "If item with ID=myDropDown has any descendent 'option' s, go do what you need to do.

My idea is that you assume that first and second members of the array are your first max and second max. Then you take each new member of an array and compare it with the 2nd max. Don't forget to compare 2nd max with the 1st one. If it's bigger, just swap them.

   public static int getMax22(int[] arr){
    int max1 = arr[0];
    int max2 = arr[1];
    for (int i = 2; i < arr.length; i++){
        if (arr[i] > max2)
        {
            max2 = arr[i];
        }

        if (max2 > max1)
        {
            int temp = max1;
            max1 = max2;
            max2 = temp;
        }
    }
     return max2;
}

The subprocess module has come along way since 2008. In particular check_call and check_output make simple subprocess stuff even easier. The check_* family of functions are nice it that they raise an exception if something goes wrong.

import os
import subprocess

files = os.listdir('.')
for f in files:
   subprocess.check_call( [ 'myscript', f ] )

Any output generated by myscript will display as though your process produced the output (technically myscript and your python script share the same stdout). There are a couple of ways to avoid this.

• check_call( [ 'myscript', f ], stdout=subprocess.PIPE )
  The stdout will be supressed (beware if myscript produces more that 4k of output). stderr will still be shown unless you add the option stderr=subprocess.PIPE.
• check_output( [ 'myscript', f ] )
check_output returns the stdout as a string so it isnt shown. stderr is still shown unless you add the option stderr=subprocess.STDOUT.

[NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToSecondButton:) userInfo:nil repeats:NO];

Is the best one to use. Using sleep(15); will cause the user unable to perform any other actions. With the following function, you would replace goToSecondButton with the appropriate selector or command, which can also be from the frameworks.

$scope.$watch('age + name', function () {
  //called when name or age changed
});

Here function will get called when both age and name value get changed.

Use a list instead and replace your foreach loop with a for loop:

@model IList<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()

    @for (var i = 0; i < Model.Count; i++) 
    {
        <tr>
            <td>
                @Html.HiddenFor(x => x[i].IP)           
                @Html.CheckBoxFor(x => x[i].Checked)
            </td>
            <td>
                @Html.DisplayFor(x => x[i].IP)
            </td>
        </tr>
    }
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

Alternatively you could use an editor template:

@model IEnumerable<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()
    @Html.EditorForModel()   
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

and then define the template ~/Views/Shared/EditorTemplates/BlockedIPViewModel.cshtml which will automatically be rendered for each element of the collection:

@model BlockedIPViewModel
<tr>
    <td>
        @Html.HiddenFor(x => x.IP)
        @Html.CheckBoxFor(x => x.Checked)
    </td>
    <td>
        @Html.DisplayFor(x => x.IP)
    </td>
</tr>

The reason you were getting null in your controller is because you didn't respect the naming convention for your input fields that the default model binder expects to successfully bind to a list. I invite you to read the following article.

Once you have read it, look at the generated HTML (and more specifically the names of the input fields) with my example and yours. Then compare and you will understand why yours doesn't work.

One of the data columns in the excel (Column Id 6) has one or more cell data that exceed the datacolumn datatype length in the database.

Verify the data in excel. Also verify the data in the excel for its format to be in compliance with the database table schema.

To avoid this, try exceeding the data-length of the string datatype in the database table.

Hope this helps.

You can setup environment variables in your code as follows:

import sys,os,os.path
sys.path.append(os.path.expanduser('~/code/eol_hsrl_python'))
os.environ['HSRL_INSTRUMENT']='gvhsrl'
os.environ['HSRL_CONFIG']=os.path.expanduser('~/hsrl_config')

This if of course a temporary fix, to get a permanent one, you probably need to export the variables into your ~.profile, more information can be found here

The correct answer to this question has been changed by the publication of RFC 8314. As a result, port 465 and 587 are both valid ports for a mail submission agent (MSA). Port 465 requires negotiation of TLS/SSL at connection setup and port 587 uses STARTTLS if one chooses to negotiate TLS. The IANA registry was updated to allow legitimate use of port 465 for this purpose. For mail relay, only port 25 is used so STARTTLS is the only way to do TLS with mail relay. It's helpful to think of mail relay and mail submission as two very different services (with many behavior differences like requiring auth, different timeouts, different message modification rules, etc.) that happen to use a similar wire protocol.

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

It is better to use scanf(" %[^\n]",str) in c++ than cin.ignore() after cin>> statement.To do that first you have to include < cstdio > header.

If you don't want add the /s regex modifier (perhaps you still want . to retain its original meaning elsewhere in the regex), you may also use a character class. One possibility:

[\S\s]

a character which is not a space or is a space. In other words, any character.

You can also change modifiers locally in a small part of the regex, like so:

Yes, a UIGestureRecognizer can be added to a UIImageView. As stated in the other answer, it is very important to remember to enable user interaction on the image view by setting its userInteractionEnabled property to YES. UIImageView inherits from UIView, whose user interaction property is set to YES by default, however, UIImageView's user interaction property is set to NO by default.

From the UIImageView docs:

New image view objects are configured to disregard user events by default. If you want to handle events in a custom subclass of UIImageView, you must explicitly change the value of the userInteractionEnabled property to YES after initializing the object.

Anyway, on the the bulk of the answer. Here's an example of how to create a UIImageView with a UIPinchGestureRecognizer, a UIRotationGestureRecognizer, and a UIPanGestureRecognizer.

First, in viewDidLoad, or another method of your choice, create an image view, give it an image, a frame, and enable its user interaction. Then create the three gestures as follows. Be sure to utilize their delegate property (most likely set to self). This will be required to use multiple gestures at the same time.

- (void)viewDidLoad
{
    [super viewDidLoad];

    // set up the image view
    UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"someImage"]];
    [imageView setBounds:CGRectMake(0.0, 0.0, 120.0, 120.0)];
    [imageView setCenter:self.view.center];
    [imageView setUserInteractionEnabled:YES]; // <--- This is very important

    // create and configure the pinch gesture
    UIPinchGestureRecognizer *pinchGestureRecognizer = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinchGestureDetected:)];
    [pinchGestureRecognizer setDelegate:self];
    [imageView addGestureRecognizer:pinchGestureRecognizer];

    // create and configure the rotation gesture
    UIRotationGestureRecognizer *rotationGestureRecognizer = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotationGestureDetected:)];
    [rotationGestureRecognizer setDelegate:self];
    [imageView addGestureRecognizer:rotationGestureRecognizer];

    // creat and configure the pan gesture
    UIPanGestureRecognizer *panGestureRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panGestureDetected:)];
    [panGestureRecognizer setDelegate:self];
    [imageView addGestureRecognizer:panGestureRecognizer];


    [self.view addSubview:imageView]; // add the image view as a subview of the view controllers view
}

Here are the three methods that will be called when the gestures on your view are detected. Inside them, we will check the current state of the gesture, and if it is in either the began or changed UIGestureRecognizerState we will read the gesture's scale/rotation/translation property, apply that data to an affine transform, apply the affine transform to the image view, and then reset the gestures scale/rotation/translation.

- (void)pinchGestureDetected:(UIPinchGestureRecognizer *)recognizer
{
    UIGestureRecognizerState state = [recognizer state];

    if (state == UIGestureRecognizerStateBegan || state == UIGestureRecognizerStateChanged)
    {
        CGFloat scale = [recognizer scale];
        [recognizer.view setTransform:CGAffineTransformScale(recognizer.view.transform, scale, scale)];
        [recognizer setScale:1.0];
    }
}

- (void)rotationGestureDetected:(UIRotationGestureRecognizer *)recognizer
{
    UIGestureRecognizerState state = [recognizer state];

    if (state == UIGestureRecognizerStateBegan || state == UIGestureRecognizerStateChanged)
    {
        CGFloat rotation = [recognizer rotation];
        [recognizer.view setTransform:CGAffineTransformRotate(recognizer.view.transform, rotation)];
        [recognizer setRotation:0];
    }
}

- (void)panGestureDetected:(UIPanGestureRecognizer *)recognizer
{
    UIGestureRecognizerState state = [recognizer state];

    if (state == UIGestureRecognizerStateBegan || state == UIGestureRecognizerStateChanged)
    {
        CGPoint translation = [recognizer translationInView:recognizer.view];
        [recognizer.view setTransform:CGAffineTransformTranslate(recognizer.view.transform, translation.x, translation.y)];
        [recognizer setTranslation:CGPointZero inView:recognizer.view];
    }
}

Finally and very importantly, you'll need to utilize the UIGestureRecognizerDelegate method gestureRecognizer: shouldRecognizeSimultaneouslyWithGestureRecognizer to allow the gestures to work at the same time. If these three gestures are the only three gestures that have this class assigned as their delegate, then you can simply return YES as shown below. However, if you have additional gestures that have this class assigned as their delegate, you may need to add logic to this method to determine which gesture is which before allowing them to all work together.

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

Don't forget to make sure that your class conforms to the UIGestureRecognizerDelegate protocol. To do so, make sure that your interface looks something like this:

@interface MyClass : MySuperClass <UIGestureRecognizerDelegate>

If you prefer to play with the code in a working sample project yourself, the sample project I've created containing this code can be found here.

one = [1, 2, 3]
two = [9, 8, 5, 3, 2, 1]

set(x in two for x in one) == set([True])

If list1 is in list 2:

• (x in two for x in one) generates a list of True.

• when we do a set(x in two for x in one) has only one element (True).

If you're more used to using ax objects to do your plotting, you might find the ax.xaxis.label.set_size() easier to remember, or at least easier to find using tab in an ipython terminal. It seems to need a redraw operation after to see the effect. For example:

import matplotlib.pyplot as plt

# set up a plot with dummy data
fig, ax = plt.subplots()
x = [0, 1, 2]
y = [0, 3, 9]
ax.plot(x,y)

# title and labels, setting initial sizes
fig.suptitle('test title', fontsize=12)
ax.set_xlabel('xlabel', fontsize=10)
ax.set_ylabel('ylabel', fontsize='medium')   # relative to plt.rcParams['font.size']

# setting label sizes after creation
ax.xaxis.label.set_size(20)
plt.draw()

I don't know of a similar way to set the suptitle size after it's created.

Update: The code in this answer is for Super CSV 1.52. Updated code examples for Super CSV 2.4.0 can be found at the project website: http://super-csv.github.io/super-csv/index.html

The SuperCSV project directly supports the parsing and structured manipulation of CSV cells. From http://super-csv.github.io/super-csv/examples_reading.html you'll find e.g.

given a class

public class UserBean {
    String username, password, street, town;
    int zip;

    public String getPassword() { return password; }
    public String getStreet() { return street; }
    public String getTown() { return town; }
    public String getUsername() { return username; }
    public int getZip() { return zip; }
    public void setPassword(String password) { this.password = password; }
    public void setStreet(String street) { this.street = street; }
    public void setTown(String town) { this.town = town; }
    public void setUsername(String username) { this.username = username; }
    public void setZip(int zip) { this.zip = zip; }
}

and that you have a CSV file with a header. Let's assume the following content

username, password,   date,        zip,  town
Klaus,    qwexyKiks,  17/1/2007,   1111, New York
Oufu,     bobilop,    10/10/2007,  4555, New York

You can then create an instance of the UserBean and populate it with values from the second line of the file with the following code

class ReadingObjects {
  public static void main(String[] args) throws Exception{
    ICsvBeanReader inFile = new CsvBeanReader(new FileReader("foo.csv"), CsvPreference.EXCEL_PREFERENCE);
    try {
      final String[] header = inFile.getCSVHeader(true);
      UserBean user;
      while( (user = inFile.read(UserBean.class, header, processors)) != null) {
        System.out.println(user.getZip());
      }
    } finally {
      inFile.close();
    }
  }
}

using the following "manipulation specification"

final CellProcessor[] processors = new CellProcessor[] {
    new Unique(new StrMinMax(5, 20)),
    new StrMinMax(8, 35),
    new ParseDate("dd/MM/yyyy"),
    new Optional(new ParseInt()),
    null
};

This is very late, but I was wondering why energee's solution works: specifically, how the <object> element affects its parent elements.

tl;dr You cannot click on an anchor that has an <object> element in it because the click events are being captured by whatever is inside of the <object> element, which then doesn't bubble it back out.

jsfiddle

To expand on the symptom described in the original question: not only will an <object> element inside an anchor element cause the anchor to become unclickable, it seems that an <object> element as a child of any element will cause click, mousedown, and mouseup events (possibly touch events too) to not fire on the parent element, (when you are clicking inside the <object>'s bounding rect.)

<span>
    <object type="image/svg+xml" data="https://icons.getbootstrap.com/icons/three-dots.svg">
    </object>
</span>

document
    .querySelector('span')
    .addEventListener('click', console.log) // will not fire

Now, <object> elements behave somewhat "like" <iframe>s, in the sense that they will establish new browsing contexts, including when the content is an <svg> document. In JavaScript, this is manifested through the existence of the HTMLObjectElement.contentDocument and HTMLObjectElement.contentWindow properties.

This means that if you add an event listener to the <svg> element inside the <object>:

document
    .querySelector('object')
    .contentDocument  // returns null if cross-origin: the same-origin policy
    .querySelector('svg')
    .addEventListener('click', console.log)

and then click on the image, you will see the events being fired.

Then it becomes clear why the pointer-events: none; solution works:

• Without this style, any MouseEvent that is considered "interactive" (such as click and mousedown, but not mouseenter) is sent to the nested browsing context inside the <object>, which will never bubble out of it.

• With this style, the MouseEvents aren't sent into the <object> in the first place, then the <object>'s parent elements will receive the events as usual.

This should explain the z-index solution as well: as long as you can prevent click events from being sent to the nested document, the clicking should work as expected.

(In my test, the z-index solution will work as long as the parent element is not inline and the <object> is positioned and has a negative z-index)

(Alternatively, you can find a way to bubble the event back up):

let objectElem = document.querySelector('object')
let svgElemt = objectElem.contentDocument.querySelector('svg')

svgElem.addEventListener('click', () => {
    window.postMessage('Take this click event please.')
    // window being the outermost window
})

window.addEventListener('message', console.log)

I found several posts telling me to run several gpg commands, but they didn't solve the problem because of two things. First, I was missing the debian-keyring package on my system and second I was using an invalid keyserver. Try different keyservers if you're getting timeouts!

Thus, the way I fixed it was:

apt-get install debian-keyring
gpg --keyserver pgp.mit.edu --recv-keys 1F41B907
gpg --armor --export 1F41B907 | apt-key add -

Then running a new "apt-get update" worked flawlessly!

Easy:

print my_queryset.query

For example:

from django.contrib.auth.models import User
print User.objects.filter(last_name__icontains = 'ax').query

It should also be mentioned that if you have DEBUG = True, then all of your queries are logged, and you can get them by accessing connection.queries:

from django.db import connections
connections['default'].queries

The django debug toolbar project uses this to present the queries on a page in a neat manner.

I would defiantly give BlackFire a try.

There is this virtualBox I've put together using puphpet, to test different php frameworks which coms with BlackFire, please feel free to fork and/or distribute if required :)

https://github.com/webit4me/PHPFrameworks

Starting Python 3.8, and the introduction of assignment expressions (PEP 572) (:= operator), we can now capture the condition value re.search(pattern, statement) in a variable (let's all it match) in order to both check if it's not None and then re-use it within the body of the condition:

if match := re.search('I love (\w+)', statement):
  print(f'He loves {match.group(1)}')
elif match := re.search("Ich liebe (\w+)", statement):
  print(f'Er liebt {match.group(1)}')
elif match := re.search("Je t'aime (\w+)", statement):
  print(f'Il aime {match.group(1)}')

As the others mentioned, it's "exec" ..

but, in case your code contains variables, you can use "global" to access it, also to prevent the compiler to raise the following error:

NameError: name 'p_variable' is not defined

exec('p_variable = [1,2,3,4]')
global p_variable
print(p_variable)

JAVACMD is an Ant specific environment variable. Ant doc says:

JAVACMD—full path of the Java executable. Use this to invoke a different JVM than JAVA_HOME/bin/java(.exe).

So, if your java.exe full path is: C:\Program Files\Java\jdk1.8.0_211\bin\java.exe, create a new environment variable called JAVACMD and set its value to the mentioned path (including \java.exe). Note that you need to close and reopen your terminal (cmd, Powershell, etc) so the new environment variable takes effect.

To create elements with equal width using Flex, you should set to your's child (flex elements):

flex-basis: 25%;
flex-grow: 0;

It will give to all elements in row 25% width. They will not grow and go one by one.

I've used the queuing approach, and it works well as you can defer that processing until your server load is idle, letting you manage your load quite effectively if you can partition off "tasks which aren't urgent" easily.

Rolling your own isn't too tricky, here's a few other options to check out:

• GearMan - this answer was written in 2009, and since then GearMan looks a popular option, see comments below.
• ActiveMQ if you want a full blown open source message queue.
• ZeroMQ - this is a pretty cool socket library which makes it easy to write distributed code without having to worry too much about the socket programming itself. You could use it for message queuing on a single host - you would simply have your webapp push something to a queue that a continuously running console app would consume at the next suitable opportunity
• beanstalkd - only found this one while writing this answer, but looks interesting
• dropr is a PHP based message queue project, but hasn't been actively maintained since Sep 2010
• php-enqueue is a recently (2017) maintained wrapper around a variety of queue systems
• Finally, a blog post about using memcached for message queuing

Another, perhaps simpler, approach is to use ignore_user_abort - once you've sent the page to the user, you can do your final processing without fear of premature termination, though this does have the effect of appearing to prolong the page load from the user perspective.

img.UriSource = new Uri("pack://application:,,,/images/" + fileName, UriKind.Absolute);

<script type="text/javascript">
    document.write(document.referrer);
</script>

document.referrer serves your purpose, but it doesn't work for Internet Explorer versions earlier than IE9.

It will work for other popular browsers, like Chrome, Mozilla, Opera, Safari etc.

To understand with words not cods:

Use Case:
With “And” the compiler will check all conditions so if you are checking that an object could be “Nothing” and then you are checking one of it’s properties you will have a run time error.
But with AndAlso with the first “false” in the conditions it will checking the next one so you will not have an error.

It's possible with a lot of work.

Basically, you have to post likes action via the Open Graph API. Then, you can add a custom design to your like button.

But then, you''ll need to keep track yourself of the likes so a returning user will be able to unlike content he liked previously.

Plus, you'll need to ask user to log into your app and ask them the publish_action permission.

All in all, if you're doing this for an application, it may worth it. For a website where you basically want user to like articles, then this is really to much.

Also, consider that you increase your drop-off rate each time you ask user a permission via a Facebook login.

If you want to see an example, I've recently made an app using the open graph like button, just hover on some photos in the mosaique to see it

Either remove one } from end of responseText;}} or from the end of the line

Here is another way:

df['rnd'] = np.random.rand(len(df)) df = df.sort_values(by='rnd', inplace=True).drop('rnd', axis=1)

MD5 also benefits from SSE2 usage, check out BarsWF and then tell me that it doesn't. All it takes is a little assembler knowledge and you can craft your own MD5 SSE2 routine(s). For large amounts of throughput however, there is a tradeoff of the speed during hashing as opposed to the time spent rearranging the input data to be compatible with the SIMD instructions used.

Starting from Java 7, the simplest way and less error prone is to simply use the command jcmd that is part of the JDK such that it will work the same way on all OS.

Example:

> jcmd
5485 sun.tools.jcmd.JCmd
2125 MyProgram

jcmd allows to send diagnostic command requests to a running Java Virtual Machine (JVM).

The following worked for me on a Windows 8.1 machine to download and prepare the setup folder, and then on a Windows 10 laptop to install:

1. Go to https://my.visualstudio.com/downloads?q=visual%20studio%20community%202015
2. Select “Visual Studio Community 2015 with Update 3” x64, English, DVD, and Download.
3. Open the folder containing the download, which is called: en_visual_studio_community_2015_with_update_3_x86_x64_dvd_8923300.iso and its size is 7,617,847,296 bytes.
4. Right-click on the file name: Mount
5. On the mount folder, shift-right-click on an empty space: Open command window here
6. On the command window: vs_community.exe /layout "blah blah blah blah \Visual Studio 2015\Setup" (or whatever path you want; the Setup folder gets created).
7. Follow the dialog box instructions.

When I did this, it remained for exactly two hours and ten secs in the Acquiring: Optional items. Don’t despair.

When it completed, the size of the Setup folder was 12.9 GB. Compare with the size of the .iso above.

After completion, I succeeded on installing without a network connection, and that even though on completion I had got the following:

I've created a factory that controls shared scope between route path's pattern, so you can maintain the shared data just when users are navigating in the same route parent path.

.controller('CadastroController', ['$scope', 'RouteSharedScope',
    function($scope, routeSharedScope) {
      var customerScope = routeSharedScope.scopeFor('/Customer');
      //var indexScope = routeSharedScope.scopeFor('/');
    }
 ])

So, if the user goes to another route path, for example '/Support', the shared data for path '/Customer' will be automatically destroyed. But, if instead of this the user goes to 'child' paths, like '/Customer/1' or '/Customer/list' the the scope won't be destroyed.

You can see an sample here: http://plnkr.co/edit/OL8of9

Use this Code for read all files in folder and sub-folders also

class Program
{
    static void Main(string[] args)
    {

        getfiles get = new getfiles();
        List<string> files =  get.GetAllFiles(@"D:\Document");

        foreach(string f in files)
        {
            Console.WriteLine(f);
        }


        Console.Read();
    }


}

class getfiles
{
    public List<string> GetAllFiles(string sDirt)
    {
        List<string> files = new List<string>();

        try
        {
            foreach (string file in Directory.GetFiles(sDirt))
            {
                files.Add(file);
            }
            foreach (string fl in Directory.GetDirectories(sDirt))
            {
                files.AddRange(GetAllFiles(fl));
            }
        }
        catch (Exception ex)
        {

            Console.WriteLine(ex.Message);
        }



        return files;
    }
}

Handler - is communication medium between threads. In android it is mostly used to communicate with main thread by creating and sending messages through handler

AsyncTask - is used to perform long running applications in a background thread. With nAsyncTask you get can do the operation in a background thread and get the result in the main thread of the application.

Thread - is a light weight process, to achieve concurrency and maximum cpu utilization. In android you can use thread to perform activities which does not touch UI of the app

The approach to loading the yaml properties, IMHO can be done in two ways:

a. You can put the configuration in a standard location - application.yml in the classpath root - typically src/main/resources and this yaml property should automatically get loaded by Spring boot with the flattened path name that you have mentioned.

b. The second approach is a little more extensive, basically define a class to hold your properties this way:

@ConfigurationProperties(path="classpath:/appprops.yml", name="db")
public class DbProperties {
    private String url;
    private String username;
    private String password;
...
}

So essentially this is saying that load the yaml file and populate the DbProperties class based on the root element of "db".

Now to use it in any class you will have to do this:

@EnableConfigurationProperties(DbProperties.class)
public class PropertiesUsingService {

    @Autowired private DbProperties dbProperties;

}

Either of these approaches should work for you cleanly using Spring-boot.

Use this:

bytes.NewBuffer(byteArray).String()

Try

CREATE TABLE foo LIKE bar;

so the keys and indexes are copied over as, well.

Documentation

File pathBinary = new File("Firefox.exe location");
FirefoxBinary ffBinary = new FirefoxBinary(pathBinary);
FirefoxProfile firefoxProfile = new FirefoxProfile();
FirefoxDriver driver = new FirefoxDriver(ffBinary,firefoxProfile);

You need to add binary of the browser

or

Best and forever solution: Just add Firefox.exe location to environmental variables

Using sorted(d.items()) isn't enough to get us a stable repr. Some of the values in d could be dictionaries too, and their keys will still come out in an arbitrary order. As long as all the keys are strings, I prefer to use:

json.dumps(d, sort_keys=True)

That said, if the hashes need to be stable across different machines or Python versions, I'm not certain that this is bulletproof. You might want to add the separators and ensure_ascii arguments to protect yourself from any changes to the defaults there. I'd appreciate comments.

Marking a controller's session state as readonly or disabled will solve the problem.

You can decorate a controller with the following attribute to mark it read-only:

[SessionState(System.Web.SessionState.SessionStateBehavior.ReadOnly)]

the System.Web.SessionState.SessionStateBehavior enum has the following values:

• Default
• Disabled
• ReadOnly
• Required

What seems easy is actually tricky if you want to be completely compatible.

var e = document.createElement('div');

Let's say you have an id of 'div1' to add.

e['id'] = 'div1';
e.id = 'div1';
e.attributes['id'] = 'div1';
e.createAttribute('id','div1')

But there are contingencies, of course. Will not work in IE prior to 8:e.attributes['style'] Will not error but won't actually set the class, it must be className:e['class'] .
However, if you're using attributes then this WILL work:e.attributes['class']

In summary, think of attributes as literal and object-oriented.

In literal, you just want it to spit out x='y' and not think about it. This is what attributes, setAttribute, createAttribute is for (except for IE's style exception). But because these are really objects things can get confused.

Since you are going to the trouble of properly creating a DOM element instead of jQuery innerHTML slop, I would treat it like one and stick with the e.className = 'fooClass' and e.id = 'fooID'. This is a design preference, but in this instance trying to treat is as anything other than an object works against you.

It will never backfire on you like the other methods might, just be aware of class being className and style being an object so it's style.width not style="width:50px". Also remember tagName but this is already set by createElement so you shouldn't need to worry about it.

This was longer than I wanted, but CSS manipulation in JS is tricky business.

you can use html entity as •

This did the job for me including active main dropdowns and the active childrens (thanks to 422):

$(document).ready(function () {
    var url = window.location;
    // Will only work if string in href matches with location
    $('ul.nav a[href="' + url + '"]').parent().addClass('active');

    // Will also work for relative and absolute hrefs
    $('ul.nav a').filter(function () {
        return this.href == url;
    }).parent().addClass('active').parent().parent().addClass('active');
});

All of them need to be vertically aligned within the div

Aligned how? Tops of the images aligned with the top of the text?

One of the images needs to be absolute positioned within the div.

Absolutely positioned relative to the DIV? Perhaps you could sketch out what you're looking for...?

fd has described the steps for absolute positioning, as well as adjusting the display of the H1 element such that images will appear inline with it. To that, i'll add that you can align the images by use of the vertical-align style:

#header h1 { display: inline; }
#header img { vertical-align: middle; }

...this would put the header and images together, with top edges aligned. Other alignment options exist; see the documentation. You might also find it beneficial to drop the DIV and move the images inside the H1 element - this provides semantic value to the container, and removes the need to adjust the display of the H1:

<h1 id=header">
   <img src=".." ></img>
   testing...
   <img src="..."></img>
</h1>

i think the main things to remember about parsing csv is that it follows some simple rules:

a)it's a text file so easily opened b) each row is determined by a line end \n so split the string into lines first c) each row/line has columns determined by a comma so split each line by that to get an array of columns

have a read of this post to see what i am talking about

it's actually very easy to do once you have the hang of it and becomes very useful.

I'll add on to mike3875's answer for future readers using Laravel 5.1 and onward.

To make things quicker, you can use the flag "--table" like this:

php artisan make:migration add_paid_to_users --table="users"

This will add the up and down method content automatically:

/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::table('users', function (Blueprint $table) {
        //
    });
}

Similarily, you can use the --create["table_name"] option when creating new migrations which will add more boilerplate to your migrations. Small point, but helpful when doing loads of them!

Other answers are correct to suggest Sort, but they seem to have missed the fact that the storage location is typed as IList<string. Sort is not part of the interface.

If you know that ListaServizi will always contain a List<string>, you can either change its declared type, or use a cast. If you're not sure, you can test the type:

if (typeof(List<string>).IsAssignableFrom(ListaServizi.GetType()))
    ((List<string>)ListaServizi).Sort();
else
{
    //... some other solution; there are a few to choose from.
}

Perhaps more idiomatic:

List<string> typeCheck = ListaServizi as List<string>;
if (typeCheck != null)
    typeCheck.Sort();
else
{
    //... some other solution; there are a few to choose from.
}

If you know that ListaServizi will sometimes hold a different implementation of IList<string>, leave a comment, and I'll add a suggestion or two for sorting it.

For me it turned out to be in c/Program Files/Java/jdk1.7.0_25/bin (Windows 8). A more general answer to this question is that it will most likely be in the bin sub directory of wherever your jdk is installed.

use case: list of item are displaying in recycler view, whenever any item click it hides recycler view and shows web view with item url.

problem: i have similar problem in which once i open a url_one in webview , then try to open another url_two in webview, it shows url_one in background till url_two is loaded.

solution: so to solve what i did is load blank string "" as url just before hiding url_one and loading url_two.

output: whenever i load any new url in webview it does not show any other web page in background.

code

public void showWebView(String url){
        webView.loadUrl(url);
        recyclerView.setVisibility(View.GONE);
        webView.setVisibility(View.VISIBLE);
    }

public void onListItemClick(String url){
   showWebView(url);
}

public void hideWebView(){
        // loading blank url so it overrides last open url
        webView.loadUrl("");
        webView.setVisibility(View.GONE);
        recyclerView.setVisibility(View.GONE);
   }


 @Override
public void onBackPressed() {
    if(webView.getVisibility() == View.VISIBLE){
        hideWebView();
    }else{
        super.onBackPressed();
    }
}

You can also do this using git remote prune origin

$ git remote prune origin
Pruning origin
URL: [email protected]/yourrepo.git
 * [pruned] origin/some-branchs

It prunes and deletes remote-tracking branches from a git branch -r listing.

Linux manual said:

EPIPE The local end has been shut down on a connection oriented socket. In this case the process will also receive a SIGPIPE unless MSG_NOSIGNAL is set.

But for Ubuntu 12.04 it isn't right. I wrote a test for that case and I always receive EPIPE withot SIGPIPE. SIGPIPE is genereated if I try to write to the same broken socket second time. So you don't need to ignore SIGPIPE if this signal happens it means logic error in your program.

I have another case when I have no chance to put CDATA into the xml as I receive the string HTML from a server.

Here is what I get from a server:

<p>The quick brown&nbsp;<br />
fox jumps&nbsp;<br />
 over the lazy dog<br />
</p>

It seems to be more complicated but the solution is much simpler.

private TextView textView;

protected void onCreate(Bundle savedInstanceState) { 
.....
textView = (TextView) findViewById(R.id.text); //need to define in your layout
String htmlFromServer = getHTMLContentFromAServer(); 
textView.setText(Html.fromHtml(htmlFromServer).toString());

}

Hope it helps!

For me adding the same host details into Putty with the private key (convert with puttygen) worked. Any git bash commands after that had no problems.

It doesn't matter is your app Boot or just raw Spring. There is just enough to inject org.springframework.core.env.Environment to your bean.

@Autowired
private Environment environment;
....

this.environment.getActiveProfiles();

super is used to call the constructor, methods and properties of parent class.

If you want to just select the id use select max(id) from customer.

If you want to select the entire row then use a query like this:

select c1.*
from customer c1, (select max(id) as max_id from customer )c2 
where c1.id=c2.max_id

c2 is an alias for the new temporary table which contains max id. Then its cross product is taken with customer table to get the entire row.

Here we are writing a query in the from clause, which can often be quite useful.

J2V8 is best solution of your problem. It's run Nodejs application on jvm(java and android).

If Character.isLetter(ch) looks a bit wordy/ugly you can use a static import.

import static java.lang.Character.*;


if(isLetter(ch)) {

} else if(isDigit(ch)) {

Sometimes the first call to cvQueryFrame() returns an empty image. Try:

IplImage *pSaveImg = cvQueryFrame(pCapturedImage);
pSaveImg = cvQueryFrame(pCapturedImage);

If that does not work, try to select capture device automatically:

CvCapture *pCapturedImage = cvCreateCameraCapture(-1);

Or you may try to select other capture devices where n=1,2,3...

CvCapture *pCapturedImage = cvCreateCameraCapture(n);

PS: Also I believe there is a misunderstanding about captured image looking at your variable name. The variable pCapturedImage is not an Image it is a Capture. You can always 'read' an image from capture.

All previous answers have overlooked that the setcookie could have been used with an explicit domain. Furthermore, the cookie might have been set on a higher subdomain, e.g. if you were on a foo.bar.tar.com domain, there might be a cookie set on tar.com. Therefore, you want to unset cookies for all domains that might have dropped the cookie:

$host = explode('.', $_SERVER['HTTP_HOST']);

while ($host) {
    $domain = '.' . implode('.', $host);

    foreach ($_COOKIE as $name => $value) {
        setcookie($name, '', 1, '/', $domain);
    }

    array_shift($host);
}

Acoording to RFC 2046 (Multipurpose Internet Mail Extensions):

The recommended action for an implementation that receives an
"application/octet-stream" entity is to simply offer to put the data in a file

So I'd go for that one.

This is because strings are immutable in Python.

Which means that X.replace("hello","goodbye") returns a copy of X with replacements made. Because of that you need replace this line:

X.replace("hello", "goodbye")

with this line:

X = X.replace("hello", "goodbye")

More broadly, this is true for all Python string methods that change a string's content "in-place", e.g. replace,strip,translate,lower/upper,join,...

You must assign their output to something if you want to use it and not throw it away, e.g.

X  = X.strip(' \t')
X2 = X.translate(...)
Y  = X.lower()
Z  = X.upper()
A  = X.join(':')
B  = X.capitalize()
C  = X.casefold()

and so on.

You have #include "fun.cpp" in mainfile.cpp so compiling with:

g++ -o hw1 mainfile.cpp

will work, however if you compile by linking these together like

g++ -g -std=c++11 -Wall -pedantic   -c -o fun.o fun.cpp
g++ -g -std=c++11 -Wall -pedantic   -c -o mainfile.o mainfile.cpp

As they mention above, adding #include "fun.hpp" will need to be done or it won't work. However, your case with the funct() function is slightly different than my problem.

I had this issue when doing a HW assignment and the autograder compiled by the lower bash recipe, yet locally it worked using the upper bash.

You can use CSS for that.

HTML (only for demo, it is customizable)

<div class="button">
    <input type="radio" name="a" value="a" id="a" />
    <label for="a">a</label>
</div>
<div class="button">
    <input type="radio" name="a" value="b" id="b" />
    <label for="b">b</label>
</div>
<div class="button">
    <input type="radio" name="a" value="c" id="c" />
    <label for="c">c</label>
</div>
...

CSS

input[type="radio"] {
    display: none;
}
input[type="radio"]:checked + label {
    border: 1px solid red;
}

You're right, the Instagram API will only return 20 images per call. So you'll have to use the pagination feature.

If you're trying to use the API console. You'll want to first allow the API console to authenticate via your Instagram login. To do this you'll want to select OAUTH2 under the Authentication dropdown.

Once Authenticated, use the left hand side menu to select the users/{user-id}/media/recent endpoint. So for the sake of this post for {user-id} you can just replace it with self. This will then use your account to retrieve information.

At a bare minimum that is what's needed to do a GET for this endpoint. Once you send, you'll get some json returned to you. At the very top of the returned information after all the server info, you'll see a pagination portion with next_url and next_max_id.

next_max_id is what you'll use as a parameter for your query. Remember max_id is the id of the image that is the oldest of the 20 that was first returned. This will be used to return images earlier than this image.

You don't have to use the max_id if you don't want to. You can actually just grab the id of the image where you'd like to start querying more images from.

So from the returned data, copy the max_id into the parameter max_id. The request URL should look something like this https://api.instagram.com/v1/users/self/media/recent?max_id=XXXXXXXXXXX where XXXXXXXXXXX is the max_id. Hit send again and you should get the next 20 photos.

From there you'll also receive an updated max_id. You can then use that again to get the next set of 20 photos until eventually going through all of the user's photos.

What I've done in the project I'm working on is to load the first 20 photos returned from the initial recent media request. I then, assign the images with a data-id (-id can actually be whatever you'd like it to be). Then added a load more button on the bottom of the photo set.

When the button is clicked, I use jQuery to grab the last image and it's data-id attribute and use that to create a get call via ajax and append the results to the end of the photos already on the page. Instead of a button you could just replace it to have a infinite scrolling effect.

Hope that helps.

Well if you know the order of your words.. you can use:

SELECT `name` FROM `table` WHERE `name` REGEXP 'Stylus.+2100'

Also you can use:

SELECT `name` FROM `table` WHERE `name` LIKE '%Stylus%' AND `name` LIKE '%2100%'

Try to add

GRANT USAGE ON SCHEMA public to readonly;

You probably were not aware that one needs to have the requisite permissions to a schema, in order to use objects in the schema.

You can use backslash either way;

string str = "He said to me, \"Hello World\". How are you?";

It prints;

He said to me, "Hello World". How are you?

which is exactly same prints with;

string str = @"He said to me, ""Hello World"". How are you?";

Here is a DEMO.

" is still part of your string.

Check out Escape Sequences and String literals from MSDN.

You can subscribe to the KeyUp event of the TextBox.

private void txtInput_KeyUp(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
       DoSomething();
}

You can also delete the branch on the remote directly. Having done that, the next update will remove it from your working copy.

svn rm "^/reponame/branches/name_of_branch" -m "cleaning up old branch name_of_branch"

The ^ is short for the URL of the remote, as seen in 'svn info'. The double quotes are necessary on Windows command line, because ^ is a special character.

This command will also work if you have never checked out the branch.

Ok, if anyone ever reads this: the best option is to add four  s at each extra level of indentation, it would seem!

If you are using .NET 3.5+ you could use LINQ (Language INtegrated Query).

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();

I always thought this was one of the better articles on the subject. It includes the following example that I think makes it clear and includes the frequently overlooked @@trancount which is needed for reliable nested transactions

PRINT 'BEFORE TRY'
BEGIN TRY
    BEGIN TRAN
     PRINT 'First Statement in the TRY block'
     INSERT INTO dbo.Account(AccountId, Name , Balance) VALUES(1, 'Account1',  10000)
     UPDATE dbo.Account SET Balance = Balance + CAST('TEN THOUSAND' AS MONEY) WHERE AccountId = 1
     INSERT INTO dbo.Account(AccountId, Name , Balance) VALUES(2, 'Account2',  20000)
     PRINT 'Last Statement in the TRY block'
    COMMIT TRAN
END TRY
BEGIN CATCH
    PRINT 'In CATCH Block'
    IF(@@TRANCOUNT > 0)
        ROLLBACK TRAN;

    THROW; -- raise error to the client
END CATCH
PRINT 'After END CATCH'
SELECT * FROM dbo.Account WITH(NOLOCK)
GO

The easiest way to do this without any framework is to use element.classList.add method.

var element = document.getElementById("div1");
element.classList.add("otherclass");

Edit: And if you want to remove class from an element -

element.classList.remove("otherclass");

I prefer not having to add any empty space and duplicate entry handling myself (which is required when using the document.className approach). There are some browser limitations, but you can work around them using polyfills.

Those reference pretty much answered your question. Simply put, vectors' lengths are dynamic while arrays have a fixed size. when using an array, you specify its size upon declaration:

int myArray[100];
myArray[0]=1;
myArray[1]=2;
myArray[2]=3;

for vectors, you just declare it and add elements

vector<int> myVector;
myVector.push_back(1);
myVector.push_back(2);
myVector.push_back(3);
...

at times you wont know the number of elements needed so a vector would be ideal for such a situation.

            var getHtmlWeb = new HtmlWeb() { AutoDetectEncoding = false, OverrideEncoding = Encoding.GetEncoding("iso-8859-2") };

            WebProxy myproxy = new WebProxy("127.0.0.1:8888", false);
            NetworkCredential cred = (NetworkCredential)CredentialCache.DefaultCredentials;
            var document = getHtmlWeb.Load("URL", "GET", myproxy, cred);

This also works in Silverlight 5 (perhaps earlier as well but i haven't tested it). I used the relative source like this and it worked fine.

RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=telerik:RadGridView}"

jspdf does not work with css but it can work along with html2canvas. You can use jspdf along with html2canvas.

include these two files in script on your page :

<script type="text/javascript" src="html2canvas.js"></script>
  <script type="text/javascript" src="jspdf.min.js"></script>
  <script type="text/javascript">
  function genPDF()
  {
   html2canvas(document.body,{
   onrendered:function(canvas){

   var img=canvas.toDataURL("image/png");
   var doc = new jsPDF();
   doc.addImage(img,'JPEG',20,20);
   doc.save('test.pdf');
   }

   });

  }
  </script>

You need to download script files such as https://github.com/niklasvh/html2canvas/releases https://cdnjs.com/libraries/jspdf

make clickable button on page so that it will generate pdf and it will be seen same as that of original html page.

<a href="javascript:genPDF()">Download PDF</a>  

It will work perfectly.

This is another way and is good to use with some text editors that are unable to correctly highlight every intricate code you create:

read -r -d '' str < <(cat somefile.txt)
echo "${#str}"
echo "$str"

With Java 7 or above you could use

ThreadLocalRandom.current().nextInt(int origin, int bound)

Javadoc: ThreadLocalRandom.nextInt

This is a common problem. Use this instead of getApplicationContext() That should solve your problem

In my case it was gcc 6 the one missing

Not mentioned yet on this thread: since C++11, the member initializer list can use list-initialization (aka. "uniform initialization", "braced initialization"):

Foo(int num): bar{num} {}

which has the same semantics as list-initialization in other contexts.

import requests
# assume sending two files
url = "put ur url here"
f1 = open("file 1 path", 'rb')
f2 = open("file 2 path", 'rb')
response = requests.post(url,files={"file1 name": f1, "file2 name":f2})
print(response)

This is because you have specified the form method as GET

And another useful command to do this (after git fetch) is:

git log origin/master ^master

This shows the commits that are in origin/master but not in master. You can also do it in opposite when doing git pull, to check what commits will be submitted to remote.

If you use sufficiently big list not in b clause will do a linear search for each of the item in a. Why not use set? Set takes iterable as parameter to create a new set object.

>>> a = ["a", "b", "c", "d", "e"]
>>> b = ["c", "d", "f", "g"]
>>> set(a).intersection(set(b))
{'c', 'd'}

right-click in your project and select Properties. In the Properties window -> "Android" -> uncheck the option "is Library" and apply -> Click "ok" to close the properties window.

This is the best answer to solve the problem

Why don't you disable the button and enable it after you finish the event?

<input type="button" id="xx" onclick="checkEnableSubmit('true');yourFunction();">

<script type="text/javascript">

function checkEnableSubmit(status) {  
  document.getElementById("xx").disabled = status;
}

function yourFunction(){

//add your functionality

checkEnableSubmit('false');
}

</script>

Happy coding !!!

As to the actual code

get your CloudFront distribution id

aws cloudfront list-distributions

Invalidate all files in the distribution, so CloudFront fetches fresh ones

aws cloudfront create-invalidation --distribution-id=S11A16G5KZMEQD --paths /

My actual full release script is

#!/usr/bin/env bash

BUCKET=mysite.com
SOURCE_DIR=dist/

export AWS_ACCESS_KEY_ID=xxxxxxxxxxx
export AWS_SECRET_ACCESS_KEY=xxxxxxxxx
export AWS_DEFAULT_REGION=eu-west-1


echo "Building production"
if npm run build:prod ; then
   echo "Build Successful"
else
  echo "exiting.."
  exit 1
fi


echo "Removing all files on bucket"
aws s3 rm s3://${BUCKET} --recursive


echo "Attempting to upload site .."
echo "Command:  aws s3  sync $SOURCE_DIR s3://$BUCKET/"
aws s3  sync ${SOURCE_DIR} s3://${BUCKET}/
echo "S3 Upload complete"

echo "Invalidating cloudfrond distribution to get fresh cache"
aws cloudfront create-invalidation --distribution-id=S11A16G5KZMEQD --paths / --profile=myawsprofile

echo "Deployment complete"

if you need a lighter solution i recommend mysql-shell, install using the command below.

brew cask install mysql-shell

To start after installation type mysqlsh.

Quick Answer:

• File --> Setting
• In left side in project section --> Project interpreter
• Select desired Project interpreter
• Apply + OK

[NOTE]:

Tested on Pycharm 2018 and 2017.

Just got rid of the error in my project. I had imported a sample project, I had changed the package folders but I had not updated the package in one of the java files.

Most likely cause of this error 'package R does not exist' is that the package name in Java or manifest file is incorrect. Make sure it is correct and in sync and then do a clean build.

I created a web site https://www.swdoc.org/ that specifically addresses the problem. So it automates swagger.json -> Asciidoc, Asciidoc -> pdf transformation as suggested in the answers. Benefit of this is that you dont need to go through the installation procedures. It accepts a spec document in form of url or just a raw json. Project is written in C# and its page is https://github.com/Irdis/SwDoc

EDIT

It might be a good idea to validate your json specs here: http://editor.swagger.io/ if you are having any problems with SwDoc, like the pdf being generated incomplete.

In Swift 2.0,

My solution to the problem is a combination of a couple of answers on this question. The problem I faced in @Phil's answer was that I couldn't change the position of the icon, and it always appeared in right the corner. And the one answer from @anatoliy_v, I couldn't resize the icon size I want to append to the string.

To make it work for me, I first did a pod 'SMIconLabel' and then created this function:

func drawTextWithIcon(labelName: SMIconLabel, imageName: String, labelText: String!,  width: Int, height: Int) {

        let newSize = CGSize(width: width, height: height)
        let image = UIImage(named: imageName)
        UIGraphicsBeginImageContextWithOptions(newSize, false, 0.0)
        image?.drawInRect(CGRectMake(0, 0, newSize.width, newSize.height))
        let imageResized = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()

        labelName.text = " \(labelText)"
        labelName.icon = imageResized
        labelName.iconPosition = .Left
    }

This solution will not only help you place the image but will also allow you to make necessary changes to the icon size and other attributes.

Thank You.

UITableView's selectRowAtIndexPath:animated:scrollPosition: should do the trick.

Just pass UITableViewScrollPositionNone for scrollPosition and the user won't see any movement.

You should also be able to manually run the action:

[theTableView.delegate tableView:theTableView didSelectRowAtIndexPath:indexPath]

after you selectRowAtIndexPath:animated:scrollPosition: so the highlight happens as well as any associated logic.

No one mentioned .env in here yet? Make a .env file in your app root, then require('dotenv').config() and read the values. Easily changed, easily read, cross platform.

https://www.npmjs.com/package/dotenv

1. You take scanf().
2. You throw it in the bin.
3. You use fgets() to get an entire line.
4. You use strtol() to parse the line as an integer, checking if it consumed the entire line.

char *end;
char buf[LINE_MAX];

do {
     if (!fgets(buf, sizeof buf, stdin))
        break;

     // remove \n
     buf[strlen(buf) - 1] = 0;

     int n = strtol(buf, &end, 10);
} while (end != buf + strlen(buf));

You can also "WAITFOR" a "TIME":

    RAISERROR('Im about to wait for a certain time...', 0, 1) WITH NOWAIT
    WAITFOR TIME '16:43:30.000'
    RAISERROR('I waited!', 0, 1) WITH NOWAIT

If you need run thread predioticly with different codes here is example:

Listener:

public interface ESLThreadListener {

    public List onBackground();

    public void onPostExecute(List list);

}

Thread Class

public class ESLThread extends AsyncTask<Void, Void, List> {


    private ESLThreadListener mListener;

    public ESLThread() {

        if(mListener != null){

            mListener.onBackground();
        }
    }

    @Override
    protected List doInBackground(Void... params) {

        if(mListener != null){

            List list = mListener.onBackground();

            return list;
        }

        return null;
    }

    @Override
    protected void onPostExecute(List t) {
        if(mListener != null){

            if ( t != null) {
                mListener.onPostExecute(t);
            }
        }

    }


    public void setListener(ESLThreadListener mListener){

        this.mListener = mListener;
    }
}

Run different codes:

  ESLThread thread = new ESLThread();
                        thread.setListener(new ESLThreadListener() {
                            @Override
                            public List onBackground() {
                                List<EntityShoppingListItems>  data = RoomDB.getDatabase(context).sliDAO().getSL(fId);

                                return data;

                            }

                            @Override
                            public void onPostExecute(List t) {

                                List<EntityShoppingListItems> data = (List<EntityShoppingListItems>)t;
                                adapter.setList(data);
                            }
                        });

                        thread.execute();

If you want to get which column values are different, you could use Entity-Attribute-Value model:

declare @Data1 xml, @Data2 xml

select @Data1 = 
(
    select * 
    from (select * from Test1 except select * from Test2) as a
    for xml raw('Data')
)

select @Data2 = 
(
    select * 
    from (select * from Test2 except select * from Test1) as a
    for xml raw('Data')
)

;with CTE1 as (
    select
        T.C.value('../@ID', 'bigint') as ID,
        T.C.value('local-name(.)', 'nvarchar(128)') as Name,
        T.C.value('.', 'nvarchar(max)') as Value
    from @Data1.nodes('Data/@*') as T(C)    
), CTE2 as (
    select
        T.C.value('../@ID', 'bigint') as ID,
        T.C.value('local-name(.)', 'nvarchar(128)') as Name,
        T.C.value('.', 'nvarchar(max)') as Value
    from @Data2.nodes('Data/@*') as T(C)     
)
select
    isnull(C1.ID, C2.ID) as ID, isnull(C1.Name, C2.Name) as Name, C1.Value as Value1, C2.Value as Value2
from CTE1 as C1
    full outer join CTE2 as C2 on C2.ID = C1.ID and C2.Name = C1.Name
where
not
(
    C1.Value is null and C2.Value is null or
    C1.Value is not null and C2.Value is not null and C1.Value = C2.Value
)

SQL FIDDLE EXAMPLE

plot has a plot.function method

plot(eq, 1, 1000)

Or

curve(eq, 1, 1000)

Should be pretty straightforward, its just the reverse of your previous method;

public static int GetEnumFromDescription(string description, Type enumType)
{
    foreach (var field in enumType.GetFields())
    {
        DescriptionAttribute attribute
            = Attribute.GetCustomAttribute(field, typeof(DescriptionAttribute))as DescriptionAttribute;
        if(attribute == null)
            continue;
        if(attribute.Description == description)
        {
            return (int) field.GetValue(null);
        }
    }
    return 0;
}

Usage:

Console.WriteLine((Animal)GetEnumFromDescription("Giant Panda",typeof(Animal)));

You can use a static lookup map to avoid the exception and return a null, then throw as you'd like:

public enum Mammal {
    COW,
    MOUSE,
    OPOSSUM;

    private static Map<String, Mammal> lookup = 
            Arrays.stream(values())
                  .collect(Collectors.toMap(Enum::name, Function.identity()));

    public static Mammal getByName(String name) {
        return lookup.get(name);
    }
}

Based on Wakas Bukhary answer, you could make it async by puting the last line in the response scope.

$('#myform').submit(function(event) {

  event.preventDefault(); //this will prevent the default submit
  var _this = $(this); //store form so it can be accessed later

  $.ajax('GET', 'url').then(function(resp) {

    // your code here 

   _this.unbind('submit').submit(); // continue the submit unbind preventDefault
  })  
}

You really shouldn't be doing this, the correct use of timeout is the right tool for the OP's problem and any other occasion where you just want to run something after a period of time. Joseph Silber has demonstrated that well in his answer. However, if in some non-production case you really want to hang the main thread for a period of time, this will do it.

function wait(ms){
   var start = new Date().getTime();
   var end = start;
   while(end < start + ms) {
     end = new Date().getTime();
  }
}

With execution in the form:

console.log('before');
wait(7000);  //7 seconds in milliseconds
console.log('after');

I've arrived here because I was building a simple test case for sequencing a mix of asynchronous operations around long-running blocking operations (i.e. expensive DOM manipulation) and this is my simulated blocking operation. It suits that job fine, so I thought I post it for anyone else who arrives here with a similar use case. Even so, it's creating a Date() object in a while loop, which might very overwhelm the GC if it runs long enough. But I can't emphasize enough, this is only suitable for testing, for building any actual functionality you should refer to Joseph Silber's answer.

It usually happens because one of the following reasons:

• Entity Set is mapped from Database view
• A custom Database query
• Database table doesn't have a primary key

After doing so, you may still need to update in the Entity Framework designer (or alternatively delete the entity and then add it) before you stop getting the error.

This error arise from the fact that you are trying to define an object of shape (0,) as an object of shape (2,). If you append what you want without forcing it to be equal to result[0] there is no any issue:

b = np.append([result[0]], [1,2])

But when you define result[0] = b you are equating objects of different shapes, and you can not do this. What are you trying to do?

Expression -- from the New Oxford American Dictionary:

expression: Mathematics a collection of symbols that jointly express a quantity : the expression for the circumference of a circle is 2pr.

In gross general terms: Expressions produce at least one value.

In Python, expressions are covered extensively in the Python Language Reference In general, expressions in Python are composed of a syntactically legal combination of Atoms, Primaries and Operators.

Python expressions from Wikipedia

Examples of expressions:

Literals and syntactically correct combinations with Operators and built-in functions or the call of a user-written functions:

>>> 23
23
>>> 23l
23L
>>> range(4)
[0, 1, 2, 3] 
>>> 2L*bin(2)
'0b100b10'
>>> def func(a):      # Statement, just part of the example...
...    return a*a     # Statement...
... 
>>> func(3)*4
36    
>>> func(5) is func(a=5)
True

Statement from Wikipedia:

In computer programming a statement can be thought of as the smallest standalone element of an imperative programming language. A program is formed by a sequence of one or more statements. A statement will have internal components (e.g., expressions).

Python statements from Wikipedia

In gross general terms: Statements Do Something and are often composed of expressions (or other statements)

The Python Language Reference covers Simple Statements and Compound Statements extensively.

The distinction of "Statements do something" and "expressions produce a value" distinction can become blurry however:

• List Comprehensions are considered "Expressions" but they have looping constructs and therfore also Do Something.
• The if is usually a statement, such as if x<0: x=0 but you can also have a conditional expression like x=0 if x<0 else 1 that are expressions. In other languages, like C, this form is called an operator like this x=x<0?0:1;
• You can write you own Expressions by writing a function. def func(a): return a*a is an expression when used but made up of statements when defined.
• An expression that returns None is a procedure in Python: def proc(): pass Syntactically, you can use proc() as an expression, but that is probably a bug...
• Python is a bit more strict than say C is on the differences between an Expression and Statement. In C, any expression is a legal statement. You can have func(x=2); Is that an Expression or Statement? (Answer: Expression used as a Statement with a side-effect.) The assignment statement of x=2 inside of the function call of func(x=2) in Python sets the named argument a to 2 only in the call to func and is more limited than the C example.

Why not just remove that attribute?

1. vanilla JS: elem.removeAttribute('disabled')
2. jQuery: elem.removeAttr('disabled')

Nullable<T> (or ?) exposes a HasValue flag to denote if a value is set or the item is null.

Also, nullable types support ==:

if (Age == null)

The ?? is the null coalescing operator and doesn't result in a boolean expression, but a value returned:

int i = Age ?? 0;

So for your example:

if (age == null || age == 0)

Or:

if (age.GetValueOrDefault(0) == 0)

Or:

if ((age ?? 0) == 0)

Or ternary:

int i = age.HasValue ? age.Value : 0;

Query to count the number of columns in a table:

select count(*) from user_tab_columns where table_name = 'tablename';

Replace tablename with the name of the table whose total number of columns you want returned.

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

Actually it is possible in JPA, although a little bit of a hack using the columnDefinition property of the @Column annotation, for example:

@Column(name="Price", columnDefinition="Decimal(10,2) default '100.00'")

I followed Alohci's recommendation of looping in reverse because it's a live nodeList. Here's what I did for those who are curious...

  var activeObjects = documents.getElementsByClassName('active'); // a live nodeList

  //Use a reverse-loop because the array is an active NodeList
  while(activeObjects.length > 0) {
    var lastElem = activePaths[activePaths.length-1]; //select the last element

    //Remove the 'active' class from the element.  
    //This will automatically update the nodeList's length too.
    var className = lastElem.getAttribute('class').replace('active','');
    lastElem.setAttribute('class', className);
  }

I read all the comments and suggestions. 500 - HTTP ERROR CODE represents internal server error.

Reasons for this error:

• These mainly cause due to permission issues
• Environment variables not found or .env file not found on your root directory
• PHP extensions problem
• Database problem

Fix:

• Set the correct permissions:

• Run these commands (Ubuntu/Debian)

find /path/to/your/root/dir/ -type f -exec chmod 644 {} \;
find /path/to/your/root/dir/ -type d -exec chmod 755 {} \;

chown -R www-data:www-data /path/to/your/root/dir/

chgrp -R www-data storage bootstrap/cache
chmod -R ug+rwx storage bootstrap/cache

• If .env file doesn't exist, create one by touch .env and paste your environment variables and then run

   php artisan key:generate
   php artisan cache:clear
   php artisan config:clear
   composer dump-autoload

• Check your php.ini file and uncomment the extensions you need (In some case you have to install the extension by running this command apt-get install php7.2-[extension-name]
• Check your database credentials and values in .env file. And grant permissions to the database user for that database.

These are some common problem you likely going to face when deploying your laravel app and once you start getting all these commands, I suggest you to make a script which will save your time.

You have to use execute immediate (dynamic sql).

DECLARE 
v_owner varchar2(40); 
v_table_name varchar2(40); 
cursor get_tables is 
select distinct table_name,user 
from user_tables 
where lower(user) = 'schema_name'; 
begin 
open get_tables; 
loop
    fetch get_tables into v_table_name,v_owner; 
    EXIT WHEN get_tables%NOTFOUND;
    execute immediate 'INSERT INTO STATS_TABLE(TABLE_NAME,SCHEMA_NAME,RECORD_COUNT,CREATED) 
    SELECT ''' || v_table_name || ''' , ''' || v_owner ||''',COUNT(*),TO_DATE(SYSDATE,''DD-MON-YY'')     FROM ' || v_table_name; 
end loop;
CLOSE get_tables; 
END; 

Are you trying to get a) Reader functionality out of InputStreamReader, or b) InputStream functionality out of InputStreamReader? You won't get b). InputStreamReader is not an InputStream.

The purpose of InputStreamReader is to take an InputStream - a source of bytes - and decode the bytes to chars in the form of a Reader. You already have your data as chars (your original String). Encoding your String into bytes and decoding the bytes back to chars would be a redundant operation.

If you are trying to get a Reader out of your source, use StringReader.

If you are trying to get an InputStream (which only gives you bytes), use apache commons IOUtils.toInputStream(..) as suggested by other answers here.

Alternatively, if using javax.net.ssl.trustStore for specifying the location of your truststore does not work ( as it did in my case for two way authentication ), you can also use SSLContextBuilder as shown in the example below. This example also includes how to create a httpclient as well to show how the SSL builder would work.

SSLContextBuilder sslcontextbuilder = SSLContexts.custom();

sslcontextbuilder.loadTrustMaterial(
            new File("C:\\path to\\truststore.jks"), //path to jks file
            "password".toCharArray(), //enters in the truststore password for use
            new TrustSelfSignedStrategy() //will trust own CA and all self-signed certs
            );

SSLContext sslcontext = sslcontextbuilder.build(); //load trust store

SSLConnectionSocketFactory sslsockfac = new SSLConnectionSocketFactory(sslcontext,new String[] { "TLSv1" },null,SSLConnectionSocketFactory.getDefaultHostnameVerifier());

CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsockfac).build(); //sets up a httpclient for use with ssl socket factory 



try { 
        HttpGet httpget = new HttpGet("https://localhost:8443"); //I had a tomcat server running on localhost which required the client to have their trust cert

        System.out.println("Executing request " + httpget.getRequestLine());

        CloseableHttpResponse response = httpclient.execute(httpget);
        try {
            HttpEntity entity = response.getEntity();

            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());

            EntityUtils.consume(entity);
        } finally {
            response.close();
        }
    } finally {
        httpclient.close();
    }

Consider this example of counting the occurrence of words in a list using dictionary comprehension

my_list = ['hello', 'hi', 'hello', 'today', 'morning', 'again', 'hello']
my_dict = {k:my_list.count(k) for k in my_list}
print(my_dict)

And the result is

{'again': 1, 'hi': 1, 'hello': 3, 'today': 1, 'morning': 1}

While creating the object for the progressbar check the following.

This fails:

dialog = new ProgressDialog(getApplicationContext());

While adding the activities context works..

dialog = new ProgressDialog(MainActivity.this);

I know this has been answered in another SOF post. However, you could do this if you know the hexadecimal.

textBox1.Background = (SolidColorBrush)new BrushConverter().ConvertFromString("#082049");

Try this if you have array and add objects to it.

$product_details = array();

foreach ($products_in_store as $key => $objects) {
  $product_details[$key] = new stdClass(); //the magic
  $product_details[$key]->product_id = $objects->id; 
   //see new object member created on the fly without warning.
}

This sends ARRAY of Objects for later use~!

You can even say:

FollowHyperlink "www.google.com"

If you get Automation Error then use http://:

ThisWorkbook.FollowHyperlink("http://www.google.com")

Very quick Interface Builder solution:

For any number of views to be evenly spaced within a superview, simply give each an "Align Center X to superview" constraint for horizontal layout, or "Align Center Y superview" for vertical layout, and set the Multiplier to be N:p (NOTE: some have had better luck with p:N - see below)

where

N = total number of views, and

p = position of the view including spaces

First position is 1, then a space, making the next position 3, so p becomes a series [1,3,5,7,9,...]. Works for any number of views.

So, if you have 3 views to space out, it looks like this:

EDIT Note: The choice of N:p or p:N depends on the relation order of your alignment constraint. If "First Item" is Superview.Center, you may use p:N, while if Superview.Center is "Second Item", you may use N:p. If in doubt, just try both out... :-)

I was able to translate my Crypto object

• Get a copy of php with mcrypt to decrypt the old data. I went to http://php.net/get/php-7.1.12.tar.gz/from/a/mirror, compiled it, then added the ext/mcrypt extension (configure;make;make install). I think I had to add the extenstion=mcrypt.so line to the php.ini as well. A series of scripts to build intermediate versions of the data with all data unencrypted.

• Build a public and private key for openssl

  openssl genrsa -des3 -out pkey.pem 2048
  (set a password)
  openssl rsa -in pkey.pem -out pkey-pub.pem -outform PEM -pubout
  

• To Encrypt (using public key) use openssl_seal. From what I've read, openssl_encrypt using an RSA key is limited to 11 bytes less than the key length (See http://php.net/manual/en/function.openssl-public-encrypt.php comment by Thomas Horsten)

  $pubKey = openssl_get_publickey(file_get_contents('./pkey-pub.pem'));
  openssl_seal($pwd, $sealed, $ekeys, [ $pubKey ]);
  $encryptedPassword = base64_encode($sealed);
  $key = base64_encode($ekeys[0]);
  

You could probably store the raw binary.

• To Decrypt (using private key)

  $passphrase="passphrase here";
  $privKey = openssl_get_privatekey(file_get_contents('./pkey.pem'), $passphrase);
  // I base64_decode() from my db columns
  openssl_open($encryptedPassword, $plain, $key, $privKey);
  echo "<h3>Password=$plain</h3>";
  

P.S. You can't encrypt the empty string ("")

P.P.S. This is for a password database not for user validation.

Set the max-width:1250px; that is currently on your body on your #container. This way your header will be 100% of his parent (body) :)

For my mac environment

sudo chown -R $USER /usr/local/lib/node_modules

solve the issue

I have pieced together the following that is hopefully simpler and cleaner than some of the existing answers and uses only the AWS CLI and no additional tools.

This code example shows how to get the value of tag 'myTag' for the current EC2 instance:

Using describe-tags:

export AWS_DEFAULT_REGION=us-east-1
instance_id=$(curl -s http://169.254.169.254/latest/meta-data/instance-id)
aws ec2 describe-tags \
  --filters "Name=resource-id,Values=$instance_id" 'Name=key,Values=myTag' \
  --query 'Tags[].Value' --output text

Or, alternatively, using describe-instances:

aws ec2 describe-instances --instance-id $instance_id \
  --query 'Reservations[].Instances[].Tags[?Key==`myTag`].Value' --output text

Just to extend the pratical scope of the question and as an appendix to the given answers: Sometimes one might find it necessary to specify the selectors a little bit more.

By defining the the full span as display:inline-block you might have a hard time displaying images.

Therefore I prefer to define a span like so:

span {
  display:block;
  width:150px;
  word-wrap:break-word;      
}
p span, a span,
h1 span, h2 span, h3 span, h4 span, h5 span {
  display:inline-block;
}
img{
  display:block;
}

The solution is so simple:

Replace type "Submit" with button

<input type="button" value="Submit" onclick="this.form.submit()" />

If the list to compare against is large, (ie the manilaListRange range in the example above), it is a smart move to use the match function. It avoids the use of a loop which could slow down the procedure. If you can ensure that the manilaListRange is all upper or lower case then this seems to be the best option to me. It is quick to apply 'UCase' or 'LCase' as you do your match.

If you did not have control over the ManilaListRange then you might have to resort to looping through this range in which case there are many ways to compare 'search', 'Instr', 'replace' etc.

A handle is like a primary key value of a record in a database.

edit 1: well, why the downvote, a primary key uniquely identifies a database record, and a handle in the Windows system uniquely identifies a window, an opened file, etc, That's what I'm saying.

(Swift 3) Add text box and uipickerview to the storyboard then add delegate and data source to uipickerview and add delegate to textbox. Follow video for assistance https://youtu.be/SfjZwgxlwcc

import UIKit

class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource, UITextFieldDelegate {

    @IBOutlet weak var textBox: UITextField!
    @IBOutlet weak var dropDown: UIPickerView!

    var list = ["1", "2", "3"]

    public func numberOfComponents(in pickerView: UIPickerView) -> Int{
        return 1
    }

    public func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{

        return list.count
    }

    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

        self.view.endEditing(true)
        return list[row]
    }

    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

        self.textBox.text = self.list[row]
        self.dropDown.isHidden = true
    }

    func textFieldDidBeginEditing(_ textField: UITextField) {

        if textField == self.textBox {
            self.dropDown.isHidden = false
            //if you don't want the users to se the keyboard type:

            textField.endEditing(true)
        }
    }
}

In case you want to cast to a class and not just a string:

YourClass model = await request.Content.ReadAsAsync<YourClass>();

you could inherit your controller then use it inside your action filter

inside your ActionFilterAttribute class:

   if( filterContext.Controller is MyController )
      if(filterContext.HttpContext.Session["login"] == null)
           (filterContext.Controller as MyController).RedirectToAction("Login");

inside your base controller:

public class MyController : Controller 
{
    public void  RedirectToAction(string actionName) { 
        base.RedirectToAction(actionName); 
    }
}

Cons. of this is to change all controllers to inherit from "MyController" class

Select count(distinct(Column_Name)) from TableName

sudo npm install npm@latest -g

This worked for me in ubuntu 18.04
