Use requests library. Try this solution, or just add https:// before the URL:

import requests
from bs4 import BeautifulSoup
import re

pages = set()
def getLinks(pageUrl):
    global pages
    html = requests.get("http://en.wikipedia.org"+pageUrl, verify=False).text
    bsObj = BeautifulSoup(html)
    for link in bsObj.findAll("a", href=re.compile("^(/wiki/)")):
        if 'href' in link.attrs:
            if link.attrs['href'] not in pages:
                #We have encountered a new page
                newPage = link.attrs['href']
                print(newPage)
                pages.add(newPage)
                getLinks(newPage)
getLinks("")

Check if this works for you

On a Mac, you need to use this command:

STATIC_DEPS=true sudo pip install lxml

Another solution would be to implement a download handler or download handler middleware. (see scrapy docs for more information on downloader middleware) The following is an example class using selenium with headless phantomjs webdriver:

1) Define class within the middlewares.py script.

from selenium import webdriver
from scrapy.http import HtmlResponse

class JsDownload(object):

    @check_spider_middleware
    def process_request(self, request, spider):
        driver = webdriver.PhantomJS(executable_path='D:\phantomjs.exe')
        driver.get(request.url)
        return HtmlResponse(request.url, encoding='utf-8', body=driver.page_source.encode('utf-8'))

2) Add JsDownload() class to variable DOWNLOADER_MIDDLEWARE within settings.py:

DOWNLOADER_MIDDLEWARES = {'MyProj.middleware.MiddleWareModule.MiddleWareClass': 500}

3) Integrate the HTMLResponse within your_spider.py. Decoding the response body will get you the desired output.

class Spider(CrawlSpider):
    # define unique name of spider
    name = "spider"

    start_urls = ["https://www.url.de"] 

    def parse(self, response):
        # initialize items
        item = CrawlerItem()

        # store data as items
        item["js_enabled"] = response.body.decode("utf-8") 

Optional Addon:
I wanted the ability to tell different spiders which middleware to use so I implemented this wrapper:

def check_spider_middleware(method):
@functools.wraps(method)
def wrapper(self, request, spider):
    msg = '%%s %s middleware step' % (self.__class__.__name__,)
    if self.__class__ in spider.middleware:
        spider.log(msg % 'executing', level=log.DEBUG)
        return method(self, request, spider)
    else:
        spider.log(msg % 'skipping', level=log.DEBUG)
        return None

return wrapper

for wrapper to work all spiders must have at minimum:

middleware = set([])

to include a middleware:

middleware = set([MyProj.middleware.ModuleName.ClassName])

Advantage:
The main advantage to implementing it this way rather than in the spider is that you only end up making one request. In A T's solution for example: The download handler processes the request and then hands off the response to the spider. The spider then makes a brand new request in it's parse_page function -- That's two requests for the same content.

I guess the answer you need is referenced here Python sets are not json serializable

Not all datatypes can be json serialized . I guess pickle module will serve your purpose.

The high voted answers didn't work for me, it seems to work for El Capitan users. But for MacOS Sierra users try the following steps

1. brew install python
2. sudo pip install --user <package name>

The default value parameter expansion is often useful in build scripts like the example one below. If the user just calls the script as-is, perl will not be built in. The user has to explicitly set WITH_PERL to a value other than "no" to have it built in.

$ cat defvar.sh
#!/bin/bash

WITH_PERL=${WITH_PERL:-no}

if [[ "$WITH_PERL" != no ]]; then
    echo "building with perl"
    # ./configure --enable=perl
else
    echo "not building with perl"
    # ./configure
fi

Build without Perl

$ ./defvar.sh
not building with perl

Build with Perl

$ WITH_PERL=yes ./defvar.sh
building with perl

Python does not require semi-colons to terminate statements. Semi colons can be used to delimit statements if you wish to put multiple statements on the same line.

Now, why is this allowed? It's a simple design decision. I don't think Python needs this semi-colon thing, but somebody thought it would be nice to have and added it to the language.

If you want to set something on a timer, you can use JavaScript's setTimeout or setInterval methods:

setTimeout ( expression, timeout );
setInterval ( expression, interval );

Where expression is a function and timeout and interval are integers in milliseconds. setTimeout runs the timer once and runs the expression once whereas setInterval will run the expression every time the interval passes.

So in your case it would work something like this:

setInterval(function() {
    //call $.ajax here
}, 5000); //5 seconds

As far as the Ajax goes, see jQuery's ajax() method. If you run an interval, there is nothing stopping you from calling the same ajax() from other places in your code.

If what you want is for an interval to run every 30 seconds until a user initiates a form submission...and then create a new interval after that, that is also possible:

setInterval() returns an integer which is the ID of the interval.

var id = setInterval(function() {
    //call $.ajax here
}, 30000); // 30 seconds

If you store that ID in a variable, you can then call clearInterval(id) which will stop the progression.

Then you can reinstantiate the setInterval() call after you've completed your ajax form submission.

This regex validates dates between 01-01-2000 and 12-31-2099 with matching separators.

EDIT - since Jul 23, 2015

The official postgres docker image will run .sql scripts found in the /docker-entrypoint-initdb.d/ folder.

So all you need is to create the following sql script:

init.sql

CREATE USER docker;
CREATE DATABASE docker;
GRANT ALL PRIVILEGES ON DATABASE docker TO docker;

and add it in your Dockerfile:

Dockerfile

FROM library/postgres
COPY init.sql /docker-entrypoint-initdb.d/

But since July 8th, 2015, if all you need is to create a user and database, it is easier to just make use to the POSTGRES_USER, POSTGRES_PASSWORD and POSTGRES_DB environment variables:

docker run -e POSTGRES_USER=docker -e POSTGRES_PASSWORD=docker -e POSTGRES_DB=docker library/postgres

or with a Dockerfile:

FROM library/postgres
ENV POSTGRES_USER docker
ENV POSTGRES_PASSWORD docker
ENV POSTGRES_DB docker

for images older than Jul 23, 2015

From the documentation of the postgres Docker image, it is said that

[...] it will source any *.sh script found in that directory [/docker-entrypoint-initdb.d] to do further initialization before starting the service

What's important here is "before starting the service". This means your script make_db.sh will be executed before the postgres service would be started, hence the error message "could not connect to database postgres".

After that there is another useful piece of information:

If you need to execute SQL commands as part of your initialization, the use of Postgres single user mode is highly recommended.

Agreed this can be a bit mysterious at the first look. What it says is that your initialization script should start the postgres service in single mode before doing its actions. So you could change your make_db.ksh script as follows and it should get you closer to what you want:

NOTE, this has changed recently in the following commit. This will work with the latest change:

export PGUSER=postgres
psql <<- EOSQL
    CREATE USER docker;
    CREATE DATABASE docker;
    GRANT ALL PRIVILEGES ON DATABASE docker TO docker;
EOSQL

Previously, the use of --single mode was required:

gosu postgres postgres --single <<- EOSQL
    CREATE USER docker;
    CREATE DATABASE docker;
    GRANT ALL PRIVILEGES ON DATABASE docker TO docker;
EOSQL

I have used the gulp-order plugin but it is not always successful as you can see by my stack overflow post gulp-order node module with merged streams. When browsing through the Gulp docs I came across the streamque module which has worked quite well for specifying order of in my case concatenation. https://github.com/gulpjs/gulp/blob/master/docs/recipes/using-multiple-sources-in-one-task.md

Example of how I used it is below

var gulp         = require('gulp');
var concat       = require('gulp-concat');
var handleErrors = require('../util/handleErrors');
var streamqueue  = require('streamqueue');

gulp.task('scripts', function() {
    return streamqueue({ objectMode: true },
        gulp.src('./public/angular/config/*.js'),
        gulp.src('./public/angular/services/**/*.js'),
        gulp.src('./public/angular/modules/**/*.js'),
        gulp.src('./public/angular/primitives/**/*.js'),
        gulp.src('./public/js/**/*.js')
    )
        .pipe(concat('app.js'))
        .pipe(gulp.dest('./public/build/js'))
        .on('error', handleErrors);
});

This one will calculate a HashCode for each object, optimized for string, number and virtually anything that has a getHashCode function. For the rest it assigns a new reference number.

(function() {
  var __gRefID = 0;
  window.getHashCode = function(ref)
  {
      if (ref == null) { throw Error("Unable to calculate HashCode on a null reference"); }

      // already cached reference id
      if (ref.hasOwnProperty("__refID")) { return ref["__refID"]; }

      // numbers are already hashcodes
      if (typeof ref === "number") { return ref; }

      // strings are immutable, so we need to calculate this every time
      if (typeof ref === "string")
      {
          var hash = 0, i, chr;
          for (i = 0; i < ref.length; i++) {
            chr = ref.charCodeAt(i);
            hash = ((hash << 5) - hash) + chr;
            hash |= 0;
          }
          return hash;
      }

      // virtual call
      if (typeof ref.getHashCode === "function") { return ref.getHashCode(); }

      // generate and return a new reference id
      return (ref["__refID"] = "ref" + __gRefID++);
  }
})();

You can simply use,

import json

json.loads(my_bytes_value)

Had the same problem with embeded youtube iframe (Translations were used for centering iframe element). None of the solutions above worked until tried reset css filters and magic happened.

Structure:

<div class="translate">
     <iframe/>
</div>

Style [before]

.translate {
  transform: translateX(-50%);
  -webkit-transform: translateX(-50%);
}

Style [after]

.translate {
  transform: translateX(-50%);
  -webkit-transform: translateX(-50%);
  filter: blur(0);
  -webkit-filter: blur(0);
}

Here is a simple and elegant way of getting filtered files

var allowedFileExtensions = ".csv,.txt";


var files = Directory.EnumerateFiles(@"C:\MyFolder", "*.*", SearchOption.TopDirectoryOnly)
                .Where(s => allowedFileExtensions.IndexOf(Path.GetExtension(s)) > -1).ToArray(); 

You array is being allocated on the stack in this case attempt to allocate an array of the same size using alloc.

Piere's answer is correct but one issue is that bulk_save_objects by default does not return the primary keys of the objects, if that is of concern to you. Set return_defaults to True to get this behavior.

The documentation is here.

foos = [Foo(bar='a',), Foo(bar='b'), Foo(bar='c')]
session.bulk_save_objects(foos, return_defaults=True)
for foo in foos:
    assert foo.id is not None
session.commit()

I am a fan of keeping logic out of the template as much as possible. I would suggest creating a helper function that returns the data that you care about to the template. For instance:

getItemsForDisplay():String[] {
 return [].concat.apply([],this.groups.map(group => group.items));
};

<tr *ngFor="let item of getItemsForDisplay()"><td>{{item}}</td></tr>

This will let you keep your presentation free of special logic. This also lets you use your datasource "directly".

Like this:

from c in db.Company
group c by c.Name into grp
where grp.Count() > 1
select grp.Key

Or, using the method syntax:

Company
    .GroupBy(c => c.Name)
    .Where(grp => grp.Count() > 1)
    .Select(grp => grp.Key);

cat /etc/*release

It's universal for almost any major distribution.

This is the one I use:

I had this issue occurring with mailto: and tel: links inside an iframe (in Chrome, not a webview). Clicking the links would show the grey "page not found" page and inspecting the page showed it had a ERR_UNKNOWN_URL_SCHEME error.

Adding target="_blank", as suggested by this discussion of the issue fixed the problem for me.

Edit: now there is yet an easier way to do this - when creating your group, just mention the full bot name (eg. @UniversalAgent1Bot) and it will list it as you type. Then you can just tap on it to add it.

Old answer:

1. Create a new group from the menu. Don't add any bots yet
2. Find the bot (for instance you can go to Contacts and search for it)
3. Tap to open
4. Tap the bot name on the top bar. Your page becomes like this:
5. Now, tap the triple ... and you will get the Add to Group button:
6. Now select your group and add the bot - and confirm the addition

Try creating a new pivot table, and not just refreshing.

I had a case where I forgot to add in a few dates. After adding them in I updated the pivot table range and hit refresh. They appeared at the end of the pivot table, out of order. I then tried to simply create a new pivot table and the dates where all in order.

$timeFirst  = strtotime('2011-05-12 18:20:20');
$timeSecond = strtotime('2011-05-13 18:20:20');
$differenceInSeconds = $timeSecond - $timeFirst;

You will then be able to use the seconds to find minutes, hours, days, etc.

I think, you haven't selected device or emulator , on which running your application,

In eclipse go to DDMS Perspective and select device or emulator on which you are running your application.

(Note: No need to restart the Eclipse)

create a new class called ComboKeyValue.java

    public class ComboKeyValue {
        private String key;
        private String value;
    
        public ComboKeyValue(String key, String value) {
            this.key = key;
            this.value = value;
        }
        
        @Override
        public String toString(){
            return key;
        }
    
        public String getKey() {
            return key;
        }
    
        public String getValue() {
            return value;
        }
}

when you want to add a new item, just write the code as below

 DefaultComboBoxModel model = new DefaultComboBoxModel();
    model.addElement(new ComboKeyValue("key", "value"));
    properties.setModel(model);

One thing missing here: if you have a varying number of elements that you want to put together to something like

WHERE [...] AND (field LIKE '%abc%' OR field LIKE '%def%')

and dont want to assemble a DQL-String yourself, you can use the orX mentioned above like this:

$patterns = ['abc', 'def'];
$orStatements = $qb->expr()->orX();
foreach ($patterns as $pattern) {
    $orStatements->add(
        $qb->expr()->like('field', $qb->expr()->literal('%' . $pattern . '%'))
    );
}
$qb->andWhere($orStatements);

This is an old question but it has a high view count, so I think some new information should be added: In the mean time a lot has changed, and you can now also use Microsoft's own .NET Core on linux. It's also available in ARM builds, 32 and 64 bit.

It sounds like something like the below will suit your needs:

With Sheets("Sheet1")
    .Rows( X & ":" & .Rows.Count).Delete
End With

Where X is a variable that = the row number ( 415 )

This is the most complicated scenario I can imagine: I have a PDF file created with Ilustrator and modified with Acrobat to have AcroFields (AcroForm) that I'm going to fill with data with this Java code, the result of that PDF file with the data in the fields is modified adding a Document.

Actually in this case I'm dynamically generating a background that is added to a PDF that is also dynamically generated with a Document with an unknown amount of data or pages.

I'm using JBoss and this code is inside a JSP file (should work in any JSP webserver).

Note: if you are using IExplorer you must submit a HTTP form with POST method to be able to download the file. If not you are going to see the PDF code in the screen. This does not happen in Chrome or Firefox.

<%@ page import="java.io.*, com.lowagie.text.*, com.lowagie.text.pdf.*" %><%

response.setContentType("application/download");
response.setHeader("Content-disposition","attachment;filename=listaPrecios.pdf" );  

// -------- FIRST THE PDF WITH THE INFO ----------
String str = "";
// lots of words
for(int i = 0; i < 800; i++) str += "Hello" + i + " ";
// the document
Document doc = new Document( PageSize.A4, 25, 25, 200, 70 );
ByteArrayOutputStream streamDoc = new ByteArrayOutputStream();
PdfWriter.getInstance( doc, streamDoc );
// lets start filling with info
doc.open();
doc.add(new Paragraph(str));
doc.close();
// the beauty of this is the PDF will have all the pages it needs
PdfReader frente = new PdfReader(streamDoc.toByteArray());
PdfStamper stamperDoc = new PdfStamper( frente, response.getOutputStream());

// -------- THE BACKGROUND PDF FILE -------
// in JBoss the file has to be in webinf/classes to be readed this way
PdfReader fondo = new PdfReader("listaPrecios.pdf");
ByteArrayOutputStream streamFondo = new ByteArrayOutputStream();
PdfStamper stamperFondo = new PdfStamper( fondo, streamFondo);
// the acroform
AcroFields form = stamperFondo.getAcroFields();
// the fields 
form.setField("nombre","Avicultura");
form.setField("descripcion","Esto describe para que sirve la lista ");
stamperFondo.setFormFlattening(true);
stamperFondo.close();
// our background is ready
PdfReader fondoEstampado = new PdfReader( streamFondo.toByteArray() );

// ---- ADDING THE BACKGROUND TO EACH DATA PAGE ---------
PdfImportedPage pagina = stamperDoc.getImportedPage(fondoEstampado,1);
int n = frente.getNumberOfPages();
PdfContentByte background;
for (int i = 1; i <= n; i++) {
    background = stamperDoc.getUnderContent(i);
    background.addTemplate(pagina, 0, 0);
}
// after this everithing will be written in response.getOutputStream()
stamperDoc.close(); 
%>

There is another solution much simpler, and solves your problem. It depends the amount of text you want to add.

// read the file
PdfReader fondo = new PdfReader("listaPrecios.pdf");
PdfStamper stamper = new PdfStamper( fondo, response.getOutputStream());
PdfContentByte content = stamper.getOverContent(1);
// add text
ColumnText ct = new ColumnText( content );
// this are the coordinates where you want to add text
// if the text does not fit inside it will be cropped
ct.setSimpleColumn(50,500,500,50);
ct.setText(new Phrase(str, titulo1));
ct.go();

I like eTicket Support, is very simple to use and install.

From the Oracle documentation page about multiple inheritance type,we can find the accurate answer here. Here we should first know the type of multiple inheritance in java:-

1. Multiple inheritance of state.
2. Multiple inheritance of implementation.
3. Multiple inheritance of type.

Java "doesn't support the multiple inheritance of state, but it support multiple inheritance of implementation with default methods since java 8 release and multiple inheritance of type with interfaces.

Then here the question arises for "diamond problem" and how Java deal with that:-

1. In case of multiple inheritance of implementation java compiler gives compilation error and asks the user to fix it by specifying the interface name. Example here:-

               interface A {
                   void method();
               }
   
               interface B extends A {
                   @Override
                   default void method() {
                       System.out.println("B");
                   }
               }
   
               interface C extends A { 
                   @Override
                   default void method() {
                       System.out.println("C");
                   }
               }
   
               interface D extends B, C {
   
               }
   

So here we will get error as:- interface D inherits unrelated defaults for method() from types B and C interface D extends B, C

You can fix it like:-

interface D extends B, C {
                @Override
                default void method() {
                    B.super.method();
                }
            }

2. In multiple inheritance of type java allows it because interface doesn't contain mutable fields and only one implementation will belong to the class so java doesn't give any issue and it allows you to do so.

In Conclusion we can say that java doesn't support multiple inheritance of state but it does support multiple inheritance of implementation and multiple inheritance of type.

There are tons of sample code online as to how to do this.

Here is just one example of how to do this: http://geekswithblogs.net/dotNETvinz/archive/2009/04/30/creating-a-simple-registration-form-in-asp.net.aspx

you define the text boxes between the following tag:

<form id="form1" runat="server"> 

you create your textboxes and define them to runat="server" like so:

<asp:TextBox ID="TxtName" runat="server"></asp:TextBox>

define a button to process your logic like so (notice the onclick):

<asp:Button ID="Button1" runat="server" Text="Save" onclick="Button1_Click" />

in the code behind, you define what you want the server to do if the user clicks on the button by defining a method named

protected void Button1_Click(object sender, EventArgs e)

or you could just double click the button in the design view.

Here is a very quick sample of code to insert into a table in the button click event (codebehind)

protected void Button1_Click(object sender, EventArgs e)

The usual way to find just the common elements in a set is to use Python's set class. Just add all the elements to the set, then convert the set to a list, and bam the duplicates are gone.

The problem, of course, is that a set() can only contain hashable entries, and a dict is not hashable.

If I had this problem, my solution would be to convert each dict into a string that represents the dict, then add all the strings to a set() then read out the string values as a list() and convert back to dict.

A good representation of a dict in string form is JSON format. And Python has a built-in module for JSON (called json of course).

The remaining problem is that the elements in a dict are not ordered, and when Python converts the dict to a JSON string, you might get two JSON strings that represent equivalent dictionaries but are not identical strings. The easy solution is to pass the argument sort_keys=True when you call json.dumps().

EDIT: This solution was assuming that a given dict could have any part different. If we can assume that every dict with the same "id" value will match every other dict with the same "id" value, then this is overkill; @gnibbler's solution would be faster and easier.

EDIT: Now there is a comment from André Lima explicitly saying that if the ID is a duplicate, it's safe to assume that the whole dict is a duplicate. So this answer is overkill and I recommend @gnibbler's answer.

void 0 returns undefined and can not be overwritten while undefined can be overwritten.

There is a very nice command line XML utility called xmlstarlet(http://xmlstar.sourceforge.net/) that can do a lot of things which a lot of people use.

You could execute this program programmatically using Runtime.exec and then read in the formatted output file. It has more options and better error reporting than a few lines of Java code can provide.

download xmlstarlet : http://sourceforge.net/project/showfiles.php?group_id=66612&package_id=64589

It's simple-

SELECT empname,
       empid,
       (SELECT COUNT (profileid)
          FROM profile
         WHERE profile.empid = employee.empid)
           AS number_of_profiles
  FROM employee;

It is even simpler when you use a table join like this:

  SELECT e.empname, e.empid, COUNT (p.profileid) AS number_of_profiles
    FROM employee e LEFT JOIN profile p ON e.empid = p.empid
GROUP BY e.empname, e.empid;

Explanation for the subquery:

Essentially, a subquery in a select gets a scalar value and passes it to the main query. A subquery in select is not allowed to pass more than one row and more than one column, which is a restriction. Here, we are passing a count to the main query, which, as we know, would always be only a number- a scalar value. If a value is not found, the subquery returns null to the main query. Moreover, a subquery can access columns from the from clause of the main query, as shown in my query where employee.empid is passed from the outer query to the inner query.

Edit:

When you use a subquery in a select clause, Oracle essentially treats it as a left join (you can see this in the explain plan for your query), with the cardinality of the rows being just one on the right for every row in the left.

Explanation for the left join

A left join is very handy, especially when you want to replace the select subquery due to its restrictions. There are no restrictions here on the number of rows of the tables in either side of the LEFT JOIN keyword.

For more information read Oracle Docs on subqueries and left join or left outer join.

Is a JNDI problem. You will see that exception if the InitialContext class has neither default properties for the JNDI service provider nor explicitly configured server properties.

Set the Context.INITIAL_CONTEXT_FACTORY environment property to the class name of the initial context implementation that you are using. This class must be available to your program in the classpath.

• http://java.sun.com/products/jndi/tutorial/getStarted/TOC.html (runtime problems)

x^y is not "x to the power of y". It's "x XOR y".

To literally change the color, you could incorporate a CSS transition with a -webkit-filter where when something happens you would invoke the -webkit-filter of your choice. For example:

img {
    -webkit-filter:grayscale(0%);
    transition: -webkit-filter .3s linear;
    }
img:hover 
    {
    -webkit-filter:grayscale(75%);
    }

theharshest's answer is the best solution, but FYI the problem you were encountering has to do with the fact that a Tag object in Beautiful Soup acts like a Python dictionary. If you access tag['name'] on a tag that doesn't have a 'name' attribute, you'll get a KeyError.

I use this all the time :

#!/usr/bin/python

l = [1,2,3,7] 
print "".join([str(x) for x in l])

If someone wants expandable/collapsible version of the treeview from Vitaliy Bychik's answer, you can save some time :)

    $('.tree li:first').show();
    $('.tree li').on('click', function (e) {

        if (children.is(":visible")) children.hide('fast');
        else children.show('fast');
        e.stopPropagation();

One nice thing about logging.exception that SiggyF's answer doesn't show is that you can pass in an arbitrary message, and logging will still show the full traceback with all the exception details:

import logging
try:
    1/0
except ZeroDivisionError:
    logging.exception("Deliberate divide by zero traceback")

With the default (in recent versions) logging behaviour of just printing errors to sys.stderr, it looks like this:

>>> import logging
>>> try:
...     1/0
... except ZeroDivisionError:
...     logging.exception("Deliberate divide by zero traceback")
... 
ERROR:root:Deliberate divide by zero traceback
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
ZeroDivisionError: integer division or modulo by zero

I tried every answer on here and none of them worked. I ended up getting it working by upping the deployment target from 10.0 to 11.0. I have no idea why that fixed it, but I suspect it has to do with upgrading to Xcode 10.2.1.

You have to close all tags like , etc for this to not show.

You don't add links to style sheets. They are for describing the style of the page. You would change your mark-up or add JavaScript to navigate when the image is clicked.

Based only on your style you would have:

I think floats may work best for you here, if you dont want the element to occupy the whole line, float it left should work.

.text span {
       background:rgba(165, 220, 79, 0.8);
       float: left;
       clear: left;
       padding:7px 10px;
       color:white;
    }

Note:Remove <br/>'s before using this off course.

If you have a readonly text box, could you not not make it a label and set AutoEllipsis=true?

alternatively there are posts with code for generating the autoellipsis yourself: (this does it for a grid, you would need to pass i the width for the text box instead. It isn't quite right as it hacks off a bit more than is necessary, and I haven;t got around to finding where the calculation is incorrect. it would be easy enough to modify to remove the first part of the directory rather than the last if you desire.

Private Function AddEllipsisPath(ByVal text As String, ByVal colIndex As Integer, ByVal grid As DataGridView) As String
    'Get the size with the column's width 
    Dim colWidth As Integer = grid.Columns(colIndex).Width

    'Calculate the dimensions of the text with the current font
    Dim textSize As SizeF = MeasureString(text, grid.Font)

    Dim rawText As String = text
    Dim FileNameLen As Integer = text.Length - text.LastIndexOf("\")
    Dim ReplaceWith As String = "\..."

    Do While textSize.Width > colWidth
        ' Trim to make room for the ellipsis
        Dim LastFolder As Integer = rawText.LastIndexOf("\", rawText.Length - FileNameLen - 1)

        If LastFolder < 0 Then
            Exit Do
        End If

        rawText = rawText.Substring(0, LastFolder) + ReplaceWith + rawText.Substring(rawText.Length - FileNameLen)

        If ReplaceWith.Length > 0 Then
            FileNameLen += 4
            ReplaceWith = ""
        End If
        textSize = MeasureString(rawText, grid.Font)
    Loop

    Return rawText
End Function

Private Function MeasureString(ByVal text As String, ByVal fontInfo As Font) As SizeF
    Dim size As SizeF
    Dim emSize As Single = fontInfo.Size
    If emSize = 0 Then emSize = 12

    Dim stringFont As New Font(fontInfo.Name, emSize)

    Dim bmp As New Bitmap(1000, 100)
    Dim g As Graphics = Graphics.FromImage(bmp)

    size = g.MeasureString(text, stringFont)

As mentioned by others, PHP 7 introduces support for the \u Unicode syntax directly.

As also mentioned by others, the only way to obtain a string value from any sensible Unicode character description in PHP, is by converting it from something else (e.g. JSON parsing, HTML parsing or some other form). But this comes at a run-time performance cost.

However, there is one other option. You can encode the character directly in PHP with \x binary escaping. The \x escape syntax is also supported in PHP 5.

This is especially useful if you prefer not to enter the character directly in a string through its natural form. For example, if it is an invisible control character, or other hard to detect whitespace.

First, a proof example:

// Unicode Character 'HAIR SPACE' (U+200A)
$htmlEntityChar = " ";
$realChar = html_entity_decode($htmlEntityChar);
$phpChar = "\xE2\x80\x8A";
echo 'Proof: ';
var_dump($realChar === $phpChar); // bool(true)

Note that, as mentioned by Pacerier in another answer, this binary code is unique to a specific character encoding. In the above example, \xE2\x80\x8A is the binary coding for U+200A in UTF-8.

The next question is, how do you get from U+200A to \xE2\x80\x8A?

Below is a PHP script to generate the escape sequence for any character, based on either a JSON string, HTML entity, or any other method once you have it as a native string.

function str_encode_utf8binary($str) {
    /** @author Krinkle 2018 */
    $output = '';
    foreach (str_split($str) as $octet) {
        $ordInt = ord($octet);
        // Convert from int (base 10) to hex (base 16), for PHP \x syntax
        $ordHex = base_convert($ordInt, 10, 16);
        $output .= '\x' . $ordHex;
    }
    return $output;
}

function str_convert_html_to_utf8binary($str) {
    return str_encode_utf8binary(html_entity_decode($str));
}
function str_convert_json_to_utf8binary($str) {
    return str_encode_utf8binary(json_decode($str));
}

// Example for raw string: Unicode Character 'INFINITY' (U+221E)
echo str_encode_utf8binary('8') . "\n";
// \xe2\x88\x9e

// Example for HTML: Unicode Character 'HAIR SPACE' (U+200A)
echo str_convert_html_to_utf8binary(' ') . "\n";
// \xe2\x80\x8a

// Example for JSON: Unicode Character 'HAIR SPACE' (U+200A)
echo str_convert_json_to_utf8binary('"\u200a"') . "\n";
// \xe2\x80\x8a

For anyone else who runs into this...

Version 1.2.0 of this plugin (current as of this post) doesn't quite work in all cases as documented with Bootstrap 3.0, but it does with a minor workaround.

Specifically, if using an input with icon, the HTML markup is of course slightly different as class names have changed:

<div class="input-group" data-datepicker="true">
    <input name="date" type="text" class="form-control" />
    <span class="input-group-addon"><i class="icon-calendar"></i></span>
</div>

It seems because of this, you need to use a selector that points directly to the input element itself NOT the parent container (which is what the auto generated HTML on the demo page suggests).

$('*[data-datepicker="true"] input[type="text"]').datepicker({
    todayBtn: true,
    orientation: "top left",
    autoclose: true,
    todayHighlight: true
});

Having done this you will probably also want to add a listener for clicking/tapping on the icon so it sets focus on the text input when clicked (which is the behaviour when using this plugin with TB 2.x by default).

$(document).on('touch click', '*[data-datepicker="true"] .input-group-addon', function(e){
    $('input[type="text"]', $(this).parent()).focus();
});

NB: I just use a data-datepicker boolean attribute because the class name 'datepicker' is reserved by the plugin and I already use 'date' for styling elements.

If you need to return an IHttpActionResult and want to return the error code plus a message, use:

return ResponseMessage(Request.CreateErrorResponse(HttpStatusCode.NotModified, "Error message here"));

You can use these functions to brutally remove everything Docker related:

removecontainers() {
    docker stop $(docker ps -aq)
    docker rm $(docker ps -aq)
}

armageddon() {
    removecontainers
    docker network prune -f
    docker rmi -f $(docker images --filter dangling=true -qa)
    docker volume rm $(docker volume ls --filter dangling=true -q)
    docker rmi -f $(docker images -qa)
}

You can add those to your ~/Xrc file, where X is your shell interpreter (~/.bashrc if you're using bash) file and reload them via executing source ~/Xrc. Also, you can just copy paste them to the console and afterwards (regardless the option you took before to get the functions ready) just run:

armageddon

It's also useful for just general Docker clean up. Have in mind that this will also remove your images, not only your containers (either running or not) and your volumes of any kind.

Json.NET has a JsonPropertyAttribute which allows you to specify the name of a JSON property, so your code should be:

public class TeamScore
{
    [JsonProperty("eighty_min_score")]
    public string EightyMinScore { get; set; }
    [JsonProperty("home_or_away")]
    public string HomeOrAway { get; set; }
    [JsonProperty("score ")]
    public string Score { get; set; }
    [JsonProperty("team_id")]
    public string TeamId { get; set; }
}

public class Team
{
    public string v1 { get; set; }
    [JsonProperty("attributes")]
    public TeamScore TeamScores { get; set; }
}

public class RootObject
{
    public List<Team> Team { get; set; }
}

By default:
join is a column-wise left join
pd.merge is a column-wise inner join
pd.concat is a row-wise outer join

pd.concat:
takes Iterable arguments. Thus, it cannot take DataFrames directly (use [df,df2])
Dimensions of DataFrame should match along axis

Join and pd.merge:
can take DataFrame arguments

Use the FROM_UNIXTIME() function in MySQL

Remember that if you are using a framework that stores it in milliseconds (for example Java's timestamp) you have to divide by 1000 to obtain the right Unix time in seconds.

I was able to resolve the issue, the resource was in my project directories but when the junit utility tries to load it, it was returning an error of MissingResourceException. And the reason was the resource was in the not on the classpath of the test class package so when I added the cfg/ folder to my classpath path entry in eclipse and set the output directory in the build conf to the same class package the issue was resolved.

When you try this approach just make sure, the classpath conf file shows the classpath entry of the resource directory (eg. cfg/)

(Google search brought me to this question even though I did not ask for perl)

I had a problem with running scripts (albeit bash not perl). Apache had a config of ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ however Apache error log showed File does not exist: /var/www/cgi-bin/test.html.

Tried putting the script in both /usr/lib/cgi-bin/ and /var/www/cgi-bin/ but neither were working.

After a prolonged googling session what cracked it for me was sudo a2enmod cgi and everything fell into place using /usr/lib/cgi-bin/.

According to http://www.techotopia.com/index.php/Ruby_String_Concatenation_and_Comparison

Doing either

mystring == yourstring

or

mystring.eql? yourstring

Are equivalent.

1. Remove all code references to System.Net.*

Here is how you get the execution path of the application:

var path = System.IO.Path.GetDirectoryName( 
      System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);

MSDN has a full reference on how to determine the Executing Application's Path.

Note that the value in path will be in the form of file:\c:\path\to\bin\folder, so before using the path you may need to strip the file:\ off the front. E.g.:

path = path.Substring(6);

numpy.fromiter() is what you are looking for:

big_array = numpy.fromiter(xrange(5), dtype="int")

It also works with generator expressions, e.g.:

big_array = numpy.fromiter( (i*(i+1)/2 for i in xrange(5)), dtype="int" )

If you know the length of the array in advance, you can specify it with an optional 'count' argument.

I found the right answer just by comparing the conversion to 1/1/1970 w/o the local time adjustment;

DateTime date = new DateTime(2011, 4, 1, 12, 0, 0, 0);
DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0);
TimeSpan span = (date - epoch);
double unixTime =span.TotalSeconds;

with in the code editor, Open the class you want to create the UID for , Right click -> Generate -> SerialVersionUID. You may need to have the GenerateSerialVersionUID plugin installed for this to work.

JavaScript automatically inserts semicolons whilst interpreting your code, so if you put the value of the return statement below the line, it won't be returned:

Your Code:

return
5

JavaScript Interpretation:

return;
5;

Thus, nothing is returned, because of JavaScript's auto semicolon insertion

Can be done via changing the Collation. By default it is case insensitive.

Excerpt from the link:

SELECT 1
FROM dbo.Customers
WHERE   CustID = @CustID COLLATE SQL_Latin1_General_CP1_CS_AS
    AND CustPassword = @CustPassword COLLATE SQL_Latin1_General_CP1_CS_AS

Or, change the columns to be case sensitive.

set DNS 8.8.4.4 and run emulator -avd react-native-device -dns-server 8.8.4.4

Not sure why this incredibly simple solution has been passed up:

#include <stdio.h>

class aClass
{
public:
    void aTest(int a, int b)
    {
        printf("%d + %d = %d\n", a, b, a + b);
    }
};

template<class C>
void function1(void (C::*function)(int, int), C& c)
{
    (c.*function)(1, 1);
}
void function1(void (*function)(int, int)) {
  function(1, 1);
}

void test(int a,int b)
{
    printf("%d - %d = %d\n", a , b , a - b);
}

int main (int argc, const char* argv[])
{
    aClass a;

    function1(&test);
    function1<aClass>(&aClass::aTest, a);
    return 0;
}

Output:

1 - 1 = 0
1 + 1 = 2

So you are doing the right thing concerning "-XX:MaxPermSize=512m": it is indeed the correct syntax. You could try to set these options directly to the Catalyna server files so they are used on server start.

Otherwise, you have function alpha in package scales in which you can directly input your vector of colors (even if they are factors as in your example):

plot(x, y, main= "Fragment recruitment plot - FR-HIT", 
     ylab = "Percent identity", xlab = "Base pair position", 
     col = alpha(cols, 0.4), pch=16) 
# For an alpha of 0.4, i. e. an opacity of 40%.

I had the same $count variable in a while loop getting lost issue.

@fedorqui's answer (and a few others) are accurate answers to the actual question: the sub-shell is indeed the problem.

But it lead me to another issue: I wasn't piping a file content... but the output of a series of pipes & greps...

my erroring sample code:

count=0
cat /etc/hosts | head | while read line; do
  ((count++))
  echo $count $line
done
echo $count

and my fix thanks to the help of this thread and the process substitution:

count=0
while IFS= read -r line; do
  ((count++))
  echo "$count $line"
done < <(cat /etc/hosts | head)
echo "$count"

try this:

#include <iostream>
using namespace std;

int main()
{
    int positiveInteger;
    int startingNumber = 1;

    cout << "Please input an integer upto 100." << endl;

    cin >> positiveInteger;

    int result = 0;
    for (int i=startingNumber; i <= positiveInteger; i++)
    {
        result += i;
        cout << result;
    }

    cout << result;

    return 0;

}

If you just want to filter null values out of a stream, you can simply use a method reference to java.util.Objects.nonNull(Object). From its documentation:

This method exists to be used as a Predicate, filter(Objects::nonNull)

For example:

List<String> list = Arrays.asList( null, "Foo", null, "Bar", null, null);

list.stream()
    .filter( Objects::nonNull )  // <-- Filter out null values
    .forEach( System.out::println );

This will print:

Foo
Bar

First of all, there are still browsers out there that don't support those pseudo-elements (ie. :first-child, :last-child), so you have to 'deal' with this issue.

There is a good example how to make that work without using pseudo-elements:

http://www.darowski.com/tracesofinspiration/2010/01/11/this-newbies-first-impressions-of-haml-and-sass/

       -- see the divider pipe example.

I hope that was useful.

Though this question has an answer, I resolved it differently when I had the same issue. I had this issue when I copied folders with the option Create Folder references; then the above solution of adding the folder to the build_path worked. But when the folder was added using the Create groups for any added folder option, the headers were picked up automatically.

In Windows OS the following commands works for me.

mysql>Use <DatabaseName>
mysql>SOURCE C:/data/ScriptFile.sql;

No single quotes or double quotes around file name. Path would contain '/' instead of '\'.

I was trying to re-install AppFabric 1.1 on my Dev Computer running Windows 8 and I get this error. I found here that adding this :

%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\  

to PSModulePath (System properties -> Environment Variables -> System variables) solved my issue.

My routes have a pattern like this:

• user/edit/1 -> Edit
• user/create/0 -> Create
• user/ -> List

When i am on Edit page, for example, and i need go back to list page, i will return 2 levels up on the route.

Thinking about that, i created my method with a "level" parameter.

goBack(level: number = 1) {
    let commands = '../';
    this.router.navigate([commands.repeat(level)], { relativeTo: this.route });
}

So, to go from edit to list i call the method like that:

this.goBack(2);

a very common try_files line which can be applied on your condition is

location / {
    try_files $uri $uri/ /test/index.html;
}

you probably understand the first part, location / matches all locations, unless it's matched by a more specific location, like location /test for example

The second part ( the try_files ) means when you receive a URI that's matched by this block try $uri first, for example http://example.com/images/image.jpg nginx will try to check if there's a file inside /images called image.jpg if found it will serve it first.

Second condition is $uri/ which means if you didn't find the first condition $uri try the URI as a directory, for example http://example.com/images/, ngixn will first check if a file called images exists then it wont find it, then goes to second check $uri/ and see if there's a directory called images exists then it will try serving it.

Side note: if you don't have autoindex on you'll probably get a 403 forbidden error, because directory listing is forbidden by default.

EDIT: I forgot to mention that if you have index defined, nginx will try to check if the index exists inside this folder before trying directory listing.

Third condition /test/index.html is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html inside the folder test and serve it if it exists.

If the third condition fails too, then nginx will serve the 404 error page.

Also there's something called named locations, like this

location @error {
}

You can call it with try_files like this

try_files $uri $uri/ @error;

TIP: If you only have 1 condition you want to serve, like for example inside folder images you only want to either serve the image or go to 404 error, you can write a line like this

location /images {
    try_files $uri =404;
}

which means either serve the file or serve a 404 error, you can't use only $uri by it self without =404 because you need to have a fallback option.
You can also choose which ever error code you want, like for example:

location /images {
    try_files $uri =403;
}

This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..

Please check in your server specification again, if you have changed your port number to something else. And change the port number in your link whatever new port number it is.

Also check whether your server is running properly before you try accessing your localhost.

A simple way to remove spaces from the whole string is to use the explode function and print the whole string using a for loop.

 $text = $_POST['string'];
            $a=explode(" ", $text);
            $count=count($a);
            for($i=0;$i<$count; $i++){

                echo $a[$i];
            }

just a matter of taste but if you prefer accessing the variable or function directly like this:

<div id="playlist-icon" back-img="playlist.icon">

instead of interpolating like this:

<div id="playlist-icon" back-img="{{playlist.icon}}">

then you can define the directive a bit differently with scope.$watch which will do $parse on the attribute

angular.module('myApp', [])
.directive('bgImage', function(){

    return function(scope, element, attrs) {
        scope.$watch(attrs.bgImage, function(value) {
            element.css({
                'background-image': 'url(' + value +')',
                'background-size' : 'cover'
            });
        });
    };
})

there is more background on this here: AngularJS : Difference between the $observe and $watch methods

In java array length is fixed.

You can use a List to hold the values and invoke the toArray method if needed See the following sample:

import java.util.List;
import java.util.ArrayList;
import java.util.Random;

public class A  {

    public static void main( String [] args ) {
        // dynamically hold the instances
        List<xClass> list = new ArrayList<xClass>();

        // fill it with a random number between 0 and 100
        int elements = new Random().nextInt(100);  
        for( int i = 0 ; i < elements ; i++ ) {
            list.add( new xClass() );
        }

        // convert it to array
        xClass [] array = list.toArray( new xClass[ list.size() ] );


        System.out.println( "size of array = " + array.length );
    }
}
class xClass {}

TCP / HTTP Listening On Ports: How Can Many Users Share the Same Port

So, what happens when a server listen for incoming connections on a TCP port? For example, let's say you have a web-server on port 80. Let's assume that your computer has the public IP address of 24.14.181.229 and the person that tries to connect to you has IP address 10.1.2.3. This person can connect to you by opening a TCP socket to 24.14.181.229:80. Simple enough.

Intuitively (and wrongly), most people assume that it looks something like this:

    Local Computer    | Remote Computer
    --------------------------------
    <local_ip>:80     | <foreign_ip>:80

    ^^ not actually what happens, but this is the conceptual model a lot of people have in mind.

This is intuitive, because from the standpoint of the client, he has an IP address, and connects to a server at IP:PORT. Since the client connects to port 80, then his port must be 80 too? This is a sensible thing to think, but actually not what happens. If that were to be correct, we could only serve one user per foreign IP address. Once a remote computer connects, then he would hog the port 80 to port 80 connection, and no one else could connect.

Three things must be understood:

1.) On a server, a process is listening on a port. Once it gets a connection, it hands it off to another thread. The communication never hogs the listening port.

2.) Connections are uniquely identified by the OS by the following 5-tuple: (local-IP, local-port, remote-IP, remote-port, protocol). If any element in the tuple is different, then this is a completely independent connection.

3.) When a client connects to a server, it picks a random, unused high-order source port. This way, a single client can have up to ~64k connections to the server for the same destination port.

So, this is really what gets created when a client connects to a server:

    Local Computer   | Remote Computer           | Role
    -----------------------------------------------------------
    0.0.0.0:80       | <none>                    | LISTENING
    127.0.0.1:80     | 10.1.2.3:<random_port>    | ESTABLISHED

Looking at What Actually Happens

First, let's use netstat to see what is happening on this computer. We will use port 500 instead of 80 (because a whole bunch of stuff is happening on port 80 as it is a common port, but functionally it does not make a difference).

    netstat -atnp | grep -i ":500 "

As expected, the output is blank. Now let's start a web server:

    sudo python3 -m http.server 500

Now, here is the output of running netstat again:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      - 

So now there is one process that is actively listening (State: LISTEN) on port 500. The local address is 0.0.0.0, which is code for "listening for all ip addresses". An easy mistake to make is to only listen on port 127.0.0.1, which will only accept connections from the current computer. So this is not a connection, this just means that a process requested to bind() to port IP, and that process is responsible for handling all connections to that port. This hints to the limitation that there can only be one process per computer listening on a port (there are ways to get around that using multiplexing, but this is a much more complicated topic). If a web-server is listening on port 80, it cannot share that port with other web-servers.

So now, let's connect a user to our machine:

    quicknet -m tcp -t localhost:500 -p Test payload.

This is a simple script (https://github.com/grokit/quickweb) that opens a TCP socket, sends the payload ("Test payload." in this case), waits a few seconds and disconnects. Doing netstat again while this is happening displays the following:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      -
    tcp        0      0 192.168.1.10:500        192.168.1.13:54240      ESTABLISHED -

If you connect with another client and do netstat again, you will see the following:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      -
    tcp        0      0 192.168.1.10:500        192.168.1.13:26813      ESTABLISHED -

... that is, the client used another random port for the connection. So there is never confusion between the IP addresses.

You can use Environment.Exit(0); and Application.Exit

Environment.Exit(0) is cleaner.

For the text after the first = and before the next =

cut -d "=" -f2 <<< "$your_str"

or

sed -e 's#.*=\(\)#\1#' <<< "$your_str"

For all text after the first = regardless of if there are multiple =

cut -d "=" -f2- <<< "$your_str"

Something like this should work:

UPDATE
    table_Name
SET 
  column_A = CASE WHEN @flag = '1' THEN column_A + @new_value ELSE column_A END,
  column_B = CASE WHEN @flag = '0' THEN column_B + @new_value ELSE column_B END
WHERE
    ID = @ID

It is because you forgot to pass in event into the click function:

$('.menuOption').on('click', function (e) { // <-- the "e" for event

    e.preventDefault(); // now it'll work

    var categories = $(this).attr('rel');
    $('.pages').hide();
    $(categories).fadeIn();
});

On a side note, e is more commonly used as opposed to the word event since Event is a global variable in most browsers.

Solution is: in anaconda (as well as in other implementations), set the path environment variable to the directory where 'python.exe' is installed.

As a default, the python.exe file in anaconda is in:

c:\.....\anaconda

after you do that, obviously, the python command works, in my case, yielding the following.

python
Python 3.4.3 |Anaconda 2.2.0. (64|bit)|(default, Nov 7 2015), etc, etc

Just to correct and slightly extend Scott Wilson answer.
You can use data.table's setnames function on data.frames too.

Do not expect speed up of the operation but you can expect the setnames to be more efficient for memory consumption as it updates column names by reference. This can be tracked with address function, see below.

library(data.table)
set.seed(123)
n = 1e8

df = data.frame(bad=sample(1:3, n, TRUE), worse=rnorm(n))
address(df)
#[1] "0x208f9f00"
colnames(df) <- c("good", "better")
address(df)
#[1] "0x208fa1d8"
rm(df)

dt = data.table(bad=sample(1:3, n, TRUE), worse=rnorm(n))
address(dt)
#[1] "0x535c830"
setnames(dt, c("good", "better"))
address(dt)
#[1] "0x535c830"
rm(dt)

So if you are hitting your memory limits you may consider to use this one instead.

It's much simpler to do this:

DateTime dt = new DateTime(633896886277130000);

Which gives

dt.ToString() ==> "9/27/2009 10:50:27 PM"

You can format this any way you want by using dt.ToString(MyFormat). Refer to this reference for format strings. "MMMM dd, yyyy" works for what you specified in the question.

Not sure where you get October 1.

Oracle Workshop for Weblogic is supposed to have a pretty nice jsp editor but I've never used it. You needn't be using Weblogic to use it.

you can add gpx files to your project and use it:
edit scheme > options > allow location simulation > pick the file name that contains for example:

<?xml version="1.0"?>
<gpx version="1.1" creator="Xcode"> 
    <wpt lat="41.92296" lon="-87.63892"></wpt>
</gpx>

optionally just hardcode the lat/lon values that are returned by the location manager. This is old style though.

so you won't add it to the simulator, but to your Xcode project.

I've found that these errors sometimes are from lack of permissions when compiling a project - so I run as administrator to get it to work properly.

Add the disable part in the submit event.

$(document).ready(function () {
    $("#yourFormId").submit(function () {
        $(".submitBtn").attr("disabled", true);
        return true;
    });
});

Try as follows:

public function funcname($id)
{
    $this->db->select('*');
    $this->db->from('Album a'); 
    $this->db->join('Category b', 'b.cat_id=a.cat_id', 'left');
    $this->db->join('Soundtrack c', 'c.album_id=a.album_id', 'left');
    $this->db->where('c.album_id',$id);
    $this->db->order_by('c.track_title','asc');         
    $query = $this->db->get(); 
    return $query->result_array();
}

If no result found CI returns false otherwise true

I agree with what @fge said, more over. Lets look at example. Consider you have a method:

class A {
    public void foo(OtherClass other) {
        SomeData data = new SomeData("Some inner data");
        other.doSomething(data);
    }
}

Now if you want to check the inner data you can use the captor:

// Create a mock of the OtherClass
OtherClass other = mock(OtherClass.class);

// Run the foo method with the mock
new A().foo(other);

// Capture the argument of the doSomething function
ArgumentCaptor<SomeData> captor = ArgumentCaptor.forClass(SomeData.class);
verify(other, times(1)).doSomething(captor.capture());

// Assert the argument
SomeData actual = captor.getValue();
assertEquals("Some inner data", actual.innerData);

The -Pattern parameter in Select-String supports an array of patterns. So the one you're looking for is:

Get-Content .\doc.txt | Select-String -Pattern (Get-Content .\regex.txt)

This searches through the textfile doc.txt by using every regex(one per line) in regex.txt

You can directly return a different view like:

return View("NameOfView", Model);

Or you can make a partial view and can return like:

return PartialView("PartialViewName", Model);

You override $today in the if statement.

if($dd<10){$dd='0'+dd} if($mm<10){$mm='0'+$mm} $today = $dd+'/'+$mm+'/'+$yyyy;

It is then not a Date() object anymore - hence the error.

In my opinion, Sergiy's answer should be the selected answer for the given question. I'm sharing my understanding.

I was looking to autoload my package files using composer which I have under the dir structure given below.

<web-root>
    |--------src/
    |           |--------App/
    |           |
    |           |--------Test/
    |
    |---------library/
    |
    |---------vendor/
    |           |
    |           |---------composer/
    |           |           |---------autoload_psr4.php
    |           |           
    |           |----------autoload.php
    |
    |-----------composer.json
    |

I'm using psr-4 autoloading specification.

Had to add below lines to the project's composer.json. I intend to place my class files inside src/App , src/Test and library directory.

"autoload": {
        "psr-4": {
            "OrgName\\AppType\\AppName\\": ["src/App", "src/Test", "library/"]
        }
    } 

This is pretty much self explaining. OrgName\AppType\AppName is my intended namespace prefix. e.g for class User in src/App/Controller/Provider/User.php -

namespace OrgName\AppType\AppName\Controller\Provider; // namespace declaration

use OrgName\AppType\AppName\Controller\Provider\User; // when using the class

Also notice "src/App", "src/Test" .. are from your web-root that is where your composer.json is. Nothing to do with the vendor dir. take a look at vendor/autoload.php

Now if composer is installed properly all that is required is #composer update

After composer update my classes loaded successfully. What I observed is that composer is adding a line in vendor/composer/autoload_psr4.php

$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);

return array(
    'Monolog\\' => array($vendorDir . '/monolog/monolog/src/Monolog'),
    'OrgName\\AppType\\AppName\\' => array($baseDir . '/src/App', $baseDir . '/src/Test', $baseDir . '/library'),
);

This is how composer maps. For psr-0 mapping is in vendor/composer/autoload_classmap.php

A bit late to the party, but that's why I wrote jenny, a small reimplementation of some core Jenkinsfile steps. (https://github.com/bmustiata/jenny)

its simple as possible by using this util method

/*
 * param@ imageView is your image you want to bordered it
 */
public static Bitmap generateBorders(ImageView imageView){
    Bitmap mbitmap = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
    Bitmap imageRounded = Bitmap.createBitmap(mbitmap.getWidth(), mbitmap.getHeight(), mbitmap.getConfig());
    Canvas canvas = new Canvas(imageRounded);
    Paint mpaint = new Paint();
    mpaint.setAntiAlias(true);
    mpaint.setShader(new BitmapShader(mbitmap, Shader.TileMode.CLAMP, Shader.TileMode.CLAMP));
    canvas.drawRoundRect((new RectF(0, 0, mbitmap.getWidth(), mbitmap.getHeight())), 100, 100, mpaint);// Round Image Corner 100 100 100 100
    return imageRounded;
}

then set your image view bitmap with returned value have fun

That should do exactly what you want. Demonstrated here.

An algorithm is a self-contained step-by-step set of operations to be performed 4, typically interpreted as a finite sequence of (computer or human) instructions to determine a solution to a problem such as: is there a path from A to B, or what is the smallest path between A and B. In the latter case, you could also be satisfied with a 'reasonably close' alternative solution.

There are certain categories of algorithms, of which the heuristic algorithm is one. Depending on the (proven) properties of the algorithm in this case, it falls into one of these three categories (note 1):

• Exact: the solution is proven to be an optimal (or exact solution) to the input problem
• Approximation: the deviation of the solution value is proven to be never further away from the optimal value than some pre-defined bound (for example, never more than 50% larger than the optimal value)
• Heuristic: the algorithm has not been proven to be optimal, nor within a pre-defined bound of the optimal solution

Notice that an approximation algorithm is also a heuristic, but with the stronger property that there is a proven bound to the solution (value) it outputs.

For some problems, noone has ever found an 'efficient' algorithm to compute the optimal solutions (note 2). One of those problems is the well-known Traveling Salesman Problem. Christophides' algorithm for the Traveling Salesman Problem, for example, used to be called a heuristic, as it was not proven that it was within 50% of the optimal solution. Since it has been proven, however, Christophides' algorithm is more accurately referred to as an approximation algorithm.

Due to restrictions on what computers can do, it is not always possible to efficiently find the best solution possible. If there is enough structure in a problem, there may be an efficient way to traverse the solution space, even though the solution space is huge (i.e. in the shortest path problem).

Heuristics are typically applied to improve the running time of algorithms, by adding 'expert information' or 'educated guesses' to guide the search direction. In practice, a heuristic may also be a sub-routine for an optimal algorithm, to determine where to look first.

(note 1): Additionally, algorithms are characterised by whether they include random or non-deterministic elements. An algorithm that always executes the same way and produces the same answer, is called deterministic.

(note 2): This is called the P vs NP problem, and problems that are classified as NP-complete and NP-hard are unlikely to have an 'efficient' algorithm. Note; as @Kriss mentioned in the comments, there are even 'worse' types of problems, which may need exponential time or space to compute.

There are several answers that answer part of the question. I deemed them less complete and not accurate enough, and decided not to edit the accepted answer made by @Kriss

I'm really late to party here, but most of the answers seem to be about the whys and whens of using assertions in general, rather than using AssertionError in particular.

assert and throw new AssertionError() are very similar and serve the same conceptual purpose, but there are differences.

1. throw new AssertionError() will throw the exception regardless of whether assertions are enabled for the jvm (i.e., through the -ea switch).
2. The compiler knows that throw new AssertionError() will exit the block, so using it will let you avoid certain compiler errors that assert will not.

For example:

    {
        boolean b = true;
        final int n;
        if ( b ) {
            n = 5;
        } else {
            throw new AssertionError();
        }
        System.out.println("n = " + n);
    }

    {
        boolean b = true;
        final int n;
        if ( b ) {
            n = 5;
        } else {
            assert false;
        }
        System.out.println("n = " + n);
    }

The first block, above, compiles just fine. The second block does not compile, because the compiler cannot guarantee that n has been initialized by the time the code tries to print it out.

1. Open the app you wish to extract the apk from on your phone.

2. Get the currently opened app with:

   adb shell dumpsys activity activities | grep mFocusedActivity
   

3. Get the path to the package name

   adb shell pm path <packagename.apk>
   

4.Copy the path you got to the sdcard directory

    adb shell cp /data/app/<packagename.apk> /sdcard

5.Pull the apk

    adb pull /sdcard/base.apk

Edit

If step no 2 doesn't work use this:

It could be quotes themselves that are the entire problem. I had a similar problem and it was due to quotes around the column name in the CREATE TABLE statement. Note there were no whitespace issues, just quotes causing problems.

The column looked like it was called anID but was really called "anID". The quotes don't appear in typical queries so it was hard to detect (for this postgres rookie). This is on postgres 9.4.1

Some more detail:

Doing postgres=# SELECT * FROM test; gave:

  anID | value 
 ------+-------
     1 | hello
     2 | baz
     3 | foo (3 rows)

but trying to select just the first column SELECT anID FROM test; resulted in an error:

ERROR:  column "anid" does not exist 
LINE 1: SELECT anID FROM test;
                ^

Just looking at the column names didn't help: postgres=# \d test;

          Table "public.test"
 Column |       Type        | Modifiers 
--------+-------------------+-----------
 anID   | integer           | not null
 value  | character varying | 
Indexes:
    "PK on ID" PRIMARY KEY, btree ("anID")

but in pgAdmin if you click on the column name and look in the SQL pane it populated with:

ALTER TABLE test ADD COLUMN "anID" integer;
ALTER TABLE test ALTER COLUMN "anID" SET NOT NULL;

and lo and behold there are the quoutes around the column name. So then ultimately postgres=# select "anID" FROM test; works fine:

 anID 
------
    1
    2
    3
(3 rows)

Same moral, don't use quotes.

If you have constant URL I recommend use simplified http-request built on apache http.

You can build your client as following:

private filan static HttpRequest<YourResponseType> httpRequest = 
                   HttpRequestBuilder.createGet(yourUri,YourResponseType)
                   .build();

public void send(){
    ResponseHendler<YourResponseType> rh = 
         httpRequest.execute(param1, value1, param2, value2);

    handler.ifSuccess(this::whenSuccess).otherwise(this::whenNotSuccess);
}

public void whenSuccess(ResponseHendler<YourResponseType> rh){
     rh.ifHasContent(content -> // your code);
}

public void whenSuccess(ResponseHendler<YourResponseType> rh){
   LOGGER.error("Status code: " + rh.getStatusCode() + ", Error msg: " + rh.getErrorText());
}

Note: There are many useful methods to manipulate your response.

Python 2.x:

print '-' * 3

Try restart Eclipse first, in my case I change different Compiler setting of the project then it shows this message, after restart it works.

The below code worked for me :)

window.open('your current page URL', '_self', '');
window.close();

Add pointer-events: none; to the overlay.

Original answer: My suggestion would be that you could capture the click event with the overlay, hide the overlay, then refire the click event, then display the overlay again. I'm not sure if you'd get a flicker effect though.

[Update] Exactly this problem and exactly my solution just appeared in this post: "Forwarding Mouse Events Through Layers". I know its probably a little late for the OP, but for the sake of somebody having this problem in the future, I though I would include it.

Verify current version of python by:

$ python --version

then check python is symbolic link to which file.

  $ ll /usr/bin/python

Output Ex:

 lrwxrwxrwx 1 root root 9 Jun 16  2014 /usr/bin/python -> python2.7*

Check other available versions of python:

$ ls /usr/bin/python*

Output Ex:

/usr/bin/python     /usr/bin/python2.7-config  /usr/bin/python3.4         /usr/bin/python3.4m-config  /usr/bin/python3.6m         /usr/bin/python3m
/usr/bin/python2    /usr/bin/python2-config    /usr/bin/python3.4-config  /usr/bin/python3.6          /usr/bin/python3.6m-config  /usr/bin/python3m-config
/usr/bin/python2.7  /usr/bin/python3           /usr/bin/python3.4m        /usr/bin/python3.6-config   /usr/bin/python3-config     /usr/bin/python-config

If want to change current version of python to 3.6 version edit file ~/.bashrc:

vim ~/.bashrc

add below line in the end of file and save:

alias python=/usr/local/bin/python3.6

To install pip for python 3.6

$ sudo apt-get install python3.6 python3.6-dev
$ sudo curl https://bootstrap.pypa.io/ez_setup.py -o - | sudo python3.6
$ sudo easy_install pip

On Success, check current version of pip:

$ pip3 -V

Output Ex:

pip 1.5.4 from /usr/lib/python3/dist-packages (python 3.6)

Building on @JustinBarber's example and noting @eric.frederich's comment, if you want to format negative values like -$1,000.00 rather than $-1,000.00 and don't want to use locale:

def as_currency(amount):
    if amount >= 0:
        return '${:,.2f}'.format(amount)
    else:
        return '-${:,.2f}'.format(-amount)

On Debian LINUX, I use: ps -o pid= -u username | xargs sudo kill -9.

With -o pid= the ps header is supressed, and the output is only the pid list. As far as I know, Debian shell is POSIX compliant.

Another good method to get an integer representation from binary is to use eval()

Like so:

def getInt(binNum = 0):
    return eval(eval('0b' + str(n)))

I guess this is a way to do it too. I hope this is a satisfactory answer :D

In the textbox add this:

textmode="Date"

It gives you nice looking Datepicker like this:

Other variations of this are:

textmode="DateTime"

It gives you this look:

textmode="DateTimeLocal"

I am not saying that you have to abandon PHP, but you need different technologies here.

Let's start off simple (without Akamai :-)) and think about the implications here. Video, chat, etc. - it's all client-side in the beginning. The user has a webcam, you want to grab the signal somehow and send it to the server. There is no PHP so far.

I know that Flash supports this though (check this tutorial on webcams and flash) so you could use Flash to transport the content to the server. I think if you'll stay with Flash, then Flex (flex and webcam tutorial) is probably a good idea to look into.

So those are just the basics, maybe it gives you an idea of where you need to research because obviously this won't give you a full video chat inside your app yet. For starters, you will need some sort of way to record the streams and re-publish them so others see other people from the chat, etc..

I'm also not sure how much traffic and bandwidth this is gonna consume though and generally, you will need way more than a Stackoverflow question to solve this issue. Best would be to do a full spec of your app and then hire some people to help you build it.

HTH!

var filteredFiles = Directory
    .EnumerateFiles(path, "*.*") // .NET4 better than `GetFiles`
    .Where(
        // ignorecase faster than tolower...
        file => file.ToLower().EndsWith("aspx")
        || file.EndsWith("ascx", StringComparison.OrdinalIgnoreCase))
    .ToList();

• Don't forget the new .NET4 Directory.EnumerateFiles for a performance boost (What is the difference between Directory.EnumerateFiles vs Directory.GetFiles?)
• "IgnoreCase" should be faster than "ToLower"

Or, it may be faster to split and merge your globs (at least it looks cleaner):

"*.ext1;*.ext2".Split(';')
    .SelectMany(g => Directory.EnumerateFiles(path, g))
    .ToList();

var str = "";
for(var k in obj)
    if (obj.hasOwnProperty(k)) //omit this test if you want to see built-in properties
        str += k + " = " + obj[k] + "\n";
alert(str);

In vi, J (that's Shift + J) or :join should do what you want, for the most part. Note that they adjust whitespace. In particular, you'll end up with a space between the two joined lines in many cases, and if the second line is indented that indentation will be removed prior to joining.

In Vim you can also use gJ (G, then Shift + J) or :join!. These will join lines without doing any whitespace adjustments.

In Vim, see :help J for more information.

use autoplay=0

autoplay takes 2 values.

Values: 0 or 1. Default is 0. Sets whether or not the initial video will autoplay when the player loads.

the important part

One thing to note - as I had exactly this problem today, depending on your HTML jQuery may or may not parse it that well. jQuery wouldn't parse my HTML into a correct DOM - on smaller XML compliant files it worked fine, but the HTML I had (that would render in a page) wouldn't parse when passed back to an Ajax callback.

In the end I simply searched manually in the string for the tag I wanted, not ideal but did work.

If you are using Python2.6 or newer, it's convenient to use socket.create_connection

sock = socket.create_connection(address, timeout=10)
sock.settimeout(None)
fileobj = sock.makefile('rb', 0)

Please, take a look at implementation of the copytree function which:

• List directory files with:

  names = os.listdir(src)

• Copy files with:

for name in names:
  srcname = os.path.join(src, name)
  dstname = os.path.join(dst, name)
  copy2(srcname, dstname)

Getting dstname is not necessary, because if destination parameter specifies a directory, the file will be copied into dst using the base filename from srcname.

Replace copy2 by move.

this might be a dirty code but i think it can suffice

<div v-for="(counter in counters">
{{ counter }}) {{ userlist[counter-1].name }}
</div>

on your script add this one

data(){return {userlist: [],user_id: '',counters: 0,edit: false,}},

document.getElementsByClassName returns an HTMLCollection(an array-like object) of all elements matching the class name. The style property is defined for Element not for HTMLCollection. You should access the first element using the bracket(subscript) notation.

document.getElementsByClassName('appBanner')[0].style.visibility = 'hidden';

Updated jsFiddle

To change the style rules of all elements matching the class, using the Selectors API:

[].forEach.call(document.querySelectorAll('.appBanner'), function (el) {
  el.style.visibility = 'hidden';
});

If for...of is available:

for (let el of document.querySelectorAll('.appBanner')) el.style.visibility = 'hidden';

All solutions I found were much more complex than necessary and none worked for me. Here is the solution that solved my problem. No need to restart mysqld or start it with special privileges.

sudo mysql

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';

With a single query we are changing the auth_plugin to mysql_native_password and setting the root password to root (feel free to change it in the query)

Now you should be able to login with root. More information can be found in mysql documentation

(exit mysql console with Ctrl + D or by typing exit)

Wherever you are trying to check NULL value of a column, you should use

IS NULL and IS NOT NULL

You should not use =NULL or ==NULL

Example(NULL)

select * from user_registration where registered_time IS NULL 

will return the rows with registered_time value is NULL

Example(NOT NULL)

select * from user_registration where registered_time IS NOT NULL 

will return the rows with registered_time value is NOT NULL

Note: The keyword null, not null and is are not case sensitive.

easy:

location.href.replace(/^http/, 'ws') + '/to/ws'
// or if you hate regexp:
location.href.replace('http://', 'ws://').replace('https://', 'wss://') + '/to/ws'

//    UITableViewCell set Identify "Cell"
//    UITableView Name is  tableReport

UIViewController,UITableViewDelegate,UITableViewDataSource,UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    @IBOutlet weak var tableReport: UITableView!  

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return 5;
        }

        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            let cell = tableReport.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
            cell.textLabel?.text = "Report Name"
            return cell;
        }
}

I know this is an old thread but stumbled upon it and found that some parts are no longer relevant.

I've found that if you want to just per-populate the text without adding a phone number, you can do the following:

sms:?&body=/* message body here */

Apparently it can be done via jQuery:

$('iframe').load( function() {
    $('iframe').contents().find("head")
      .append($("<style type='text/css'>  .my-class{display:none;}  </style>"));
});

Just solved this problem! I know the question is quite old, but I just had this same problem and none of the answers above helped to solve it.

Assuming the actual domain name you want to use is specified in your c:\windows\System32\drivers\etc\hosts and your configurations in apache\conf\httpd.conf and apache\conf\extra\httpd-vhots.conf are right, your problem might be the same as mine:

In Apache's htdocs directory I had a shortcut linking to the actual project I wanted to see in the browser. It turns out, Apache doesn't understand shortcuts. My solution was to create a proper symlink:

In windows, and within the httdocs directory, I ran this command in the terminal:

mklink /d ple <your project directory with index.html> 

This created a proper symlink in the httpdocs directory. After restarting the Apache service and then reloading the page, I was able to see my website up :)

Kotlin: In fragment.kt -> onCreateView()

       super.onCreateOptionsMenu(menu, inflater)

   override fun onOptionsItemSelected(item: MenuItem): Boolean {
        return when (item.itemId) {
             R.id.selected_id->{//to_do}

The delete[] operator is used to delete arrays. The delete operator is used to delete non-array objects. It calls operator delete[] and operator delete function respectively to delete the memory that the array or non-array object occupied after (eventually) calling the destructors for the array's elements or the non-array object.

The following shows the relations:

typedef int array_type[1];

// create and destroy a int[1]
array_type *a = new array_type;
delete [] a;

// create and destroy an int
int *b = new int;
delete b;

// create and destroy an int[1]
int *c = new int[1];
delete[] c;

// create and destroy an int[1][2]
int (*d)[2] = new int[1][2];
delete [] d;

For the new that creates an array (so, either the new type[] or new applied to an array type construct), the Standard looks for an operator new[] in the array's element type class or in the global scope, and passes the amount of memory requested. It may request more than N * sizeof(ElementType) if it wants (for instance to store the number of elements, so it later when deleting knows how many destructor calls to done). If the class declares an operator new[] that additional to the amount of memory accepts another size_t, that second parameter will receive the number of elements allocated - it may use this for any purpose it wants (debugging, etc...).

For the new that creates a non-array object, it will look for an operator new in the element's class or in the global scope. It passes the amount of memory requested (exactly sizeof(T) always).

For the delete[], it looks into the arrays' element class type and calls their destructors. The operator delete[] function used is the one in the element type's class, or if there is none then in the global scope.

For the delete, if the pointer passed is a base class of the actual object's type, the base class must have a virtual destructor (otherwise, behavior is undefined). If it is not a base class, then the destructor of that class is called, and an operator delete in that class or the global operator delete is used. If a base class was passed, then the actual object type's destructor is called, and the operator delete found in that class is used, or if there is none, a global operator delete is called. If the operator delete in the class has a second parameter of type size_t, it will receive the number of elements to deallocate.

I recommend you to use JSON.NET. it is an open source library to serialize and deserialize your c# objects into json and Json objects into .net objects ...

Serialization Example:

Product product = new Product();
product.Name = "Apple";
product.Expiry = new DateTime(2008, 12, 28);
product.Price = 3.99M;
product.Sizes = new string[] { "Small", "Medium", "Large" };

string json = JsonConvert.SerializeObject(product);
//{
//  "Name": "Apple",
//  "Expiry": new Date(1230422400000),
//  "Price": 3.99,
//  "Sizes": [
//    "Small",
//    "Medium",
//    "Large"
//  ]
//}

Product deserializedProduct = JsonConvert.DeserializeObject<Product>(json);

Performance Comparison To Other JSON serializiation Techniques

Pretty easy to overlook like I did, but don't forget to use UITapGestureRecognizer rather than UIGestureRecognizer.

As everyone else has said, @require only gets run when the script has installed. However, you should note as well that currently jQuery 1.4.* doesn't work with greasemonkey. You can see here for details: http://forum.jquery.com/topic/importing-jquery-1-4-1-into-greasemonkey-scripts-generates-an-error

You will have to use jQuery 1.3.2 until things change.

Use any of the following groupby and agg recipes.

# Setup
df = pd.DataFrame({
  'a': ['A', 'A', 'B', 'B', 'B', 'C'],
  'b': [1, 2, 5, 5, 4, 6],
  'c': ['x', 'y', 'z', 'x', 'y', 'z']
})
df

   a  b  c
0  A  1  x
1  A  2  y
2  B  5  z
3  B  5  x
4  B  4  y
5  C  6  z

To aggregate multiple columns as lists, use any of the following:

df.groupby('a').agg(list)
df.groupby('a').agg(pd.Series.tolist)

           b          c
a                      
A     [1, 2]     [x, y]
B  [5, 5, 4]  [z, x, y]
C        [6]        [z]

To group-listify a single column only, convert the groupby to a SeriesGroupBy object, then call SeriesGroupBy.agg. Use,

df.groupby('a').agg({'b': list})  # 4.42 ms 
df.groupby('a')['b'].agg(list)    # 2.76 ms - faster

a
A       [1, 2]
B    [5, 5, 4]
C          [6]
Name: b, dtype: object

        <div ng-if="!someothervar">_x000D_
            object (with ng-if): <input type="checkbox" ng-model="obj.test" />_x000D_
        </div>_x000D_
        _x000D_
    </div>_x000D_
</div>

So, your checkbox changes the testb inside of the child scope, but not the outer parent scope.

Note, that if you want to modify the data in the parent scope, you'll need to modify the internal properties of an object like in the last div that I added.

If you want to do it typed:

class Something {

  areas: Area[][];

  constructor() {
    this.areas = new Array<Array<Area>>();
    for (let y = 0; y <= 100; y++) {
      let row:Area[]  = new Array<Area>();      
      for (let x = 0; x <=100; x++){
        row.push(new Area(x, y));
      }
      this.areas.push(row);
    }
  }
}

I saw in getwindowtext (user32) on pinvoke.net that you can place a MarshalAs statement to state that the StringBuffer is equivalent to LPSTR.

<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Ansi)> _
Public Function GetWindowText(hwnd As IntPtr, <MarshalAs(UnManagedType.LPStr)>lpString As System.Text.StringBuilder, cch As Integer) As Integer
End Function

Note also, the string has a operator[] which returns a Char, and is an IEnumerable<char>, so for most purposes, you can use a string as a char[]. Hence:

string alpha = "ABCDEFGHIJKLMNOPQRSTUVQXYZ";
for (int i =0; i < 26; ++i)
{  
     Console.WriteLine(alpha[i]);
}

foreach(char c in alpha)
{  
     Console.WriteLine(c);
}

Differences

• KEY or INDEX refers to a normal non-unique index. Non-distinct values for the index are allowed, so the index may contain rows with identical values in all columns of the index. These indexes don't enforce any restraints on your data so they are used only for access - for quickly reaching certain ranges of records without scanning all records.

• UNIQUE refers to an index where all rows of the index must be unique. That is, the same row may not have identical non-NULL values for all columns in this index as another row. As well as being used to quickly reach certain record ranges, UNIQUE indexes can be used to enforce restraints on data, because the database system does not allow the distinct values rule to be broken when inserting or updating data.

  Your database system may allow a UNIQUE index to be applied to columns which allow NULL values, in which case two rows are allowed to be identical if they both contain a NULL value (the rationale here is that NULL is considered not equal to itself). Depending on your application, however, you may find this undesirable: if you wish to prevent this, you should disallow NULL values in the relevant columns.

• PRIMARY acts exactly like a UNIQUE index, except that it is always named 'PRIMARY', and there may be only one on a table (and there should always be one; though some database systems don't enforce this). A PRIMARY index is intended as a primary means to uniquely identify any row in the table, so unlike UNIQUE it should not be used on any columns which allow NULL values. Your PRIMARY index should be on the smallest number of columns that are sufficient to uniquely identify a row. Often, this is just one column containing a unique auto-incremented number, but if there is anything else that can uniquely identify a row, such as "countrycode" in a list of countries, you can use that instead.

  Some database systems (such as MySQL's InnoDB) will store a table's records on disk in the order in which they appear in the PRIMARY index.

• FULLTEXT indexes are different from all of the above, and their behaviour differs significantly between database systems. FULLTEXT indexes are only useful for full text searches done with the MATCH() / AGAINST() clause, unlike the above three - which are typically implemented internally using b-trees (allowing for selecting, sorting or ranges starting from left most column) or hash tables (allowing for selection starting from left most column).

  Where the other index types are general-purpose, a FULLTEXT index is specialised, in that it serves a narrow purpose: it's only used for a "full text search" feature.

Similarities

• All of these indexes may have more than one column in them.

• With the exception of FULLTEXT, the column order is significant: for the index to be useful in a query, the query must use columns from the index starting from the left - it can't use just the second, third or fourth part of an index, unless it is also using the previous columns in the index to match static values. (For a FULLTEXT index to be useful to a query, the query must use all columns of the index.)

Initialize all your array elements to null first, then look for the null to find the empty slot

You would use the replace method:

text = text.replace('old', 'new');

The first argument is what you're looking for, obviously. It can also accept regular expressions.

Just remember that it does not change the original string. It only returns the new value.

input element, of type file

<input id="fileInput" type="file" />

On your input change use the FileReader object and read your input file property:

$('#fileInput').on('change', function () {
    var fileReader = new FileReader();
    fileReader.onload = function () {
      var data = fileReader.result;  // data <-- in this var you have the file data in Base64 format
    };
    fileReader.readAsDataURL($('#fileInput').prop('files')[0]);
});

FileReader will load your file and in fileReader.result you have the file data in Base64 format (also the file content-type (MIME), text/plain, image/jpg, etc)

How about:

<asp:HtmlIframe ID="yourIframe" runat="server" />

Is supported since .Net Framework 4.5

If you have Problems using this control, you might take a look here.

I think this code will resolve your issue. Copy and paste this code on your MainActivity.java

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

    View decorView = getWindow().getDecorView();
    decorView.setOnSystemUiVisibilityChangeListener
    (new View.OnSystemUiVisibilityChangeListener() {
        @Override
        public void onSystemUiVisibilityChange(int visibility) {

            if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
                hideNavigationBar();
            } 
        }
    });
}



private void hideNavigationBar() {
   getWindow().getDecorView().setSystemUiVisibility(
        View.SYSTEM_UI_FLAG_HIDE_NAVIGATION|
        View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}

It will works on Android-10. I hope it will helps.

If you have a big nested JSON object and using it across several screens, you might face performance issues in page loading. I always go for small individual JSON objects and query the related objects as lazy load only where they are required.

you can achieve it using ng-init

<td class="lectureClass" ng-repeat="s in sessions" ng-init='presenters=getPresenters(s.id)'>
      {{s.name}}
      <div class="presenterClass" ng-repeat="p in presenters">
          {{p.name}}
      </div>
</td> 

The code on the controller side should look like below

$scope.getPresenters = function(id) {
    return SessionPresenters.get({id: id});
};

While the API factory is as follows:

angular.module('tryme3App').factory('SessionPresenters', function ($resource, DateUtils) {

        return $resource('api/session.Presenters/:id', {}, {
            'query': { method: 'GET', isArray: true},
            'get': {
                method: 'GET', isArray: true
            },
            'update': { method:'PUT' }
        });
    });

I dug myself into a slight variant on this problem by mistakenly running the setfacl command. I ran:

sudo setfacl -m user:nginx:r /home/foo/bar

I abandoned this route in favor of adding nginx to the foo group, but that custom ACL was foiling nginx's attempts to access the file. I cleared it by running:

sudo setfacl -b /home/foo/bar

And then nginx was able to access the files.

The best format to use is "yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffK".

The last K on string will be changed to 'Z' if the date is UTC or with timezone (+-hh:mm) if is local. (http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx)

As LukeH said, is good to use the ToUniversalTime if you want that all the dates will be UTC.

The final code is:

string foo = yourDateTime.ToUniversalTime()
                         .ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffK");

The two things that helped me best when learning about there were:

Chapter 8, "Functional Parsers," from Graham Hutton's book Programming in Haskell. This doesn't mention monads at all, actually, but if you can work through chapter and really understand everything in it, particularly how a sequence of bind operations is evaluated, you'll understand the internals of monads. Expect this to take several tries.

The tutorial All About Monads. This gives several good examples of their use, and I have to say that the analogy in Appendex I worked for me.

If you don't mind cloning the entire directory, this small bash/zsh function will have the end result of cloning a single file into your current directory (by cloning the repo into a temp directory and removing it afterwards).

Pro: You only get the file you want

Con: You still have to wait for the whole repo to clone

git-single-file () {
        if [ $# -lt 2 ]
        then
                echo "Usage: $0 <repo url> <file path>"
                return
        fi
        TEMP_DIR=$(mktemp -d)
        git clone $1 $TEMP_DIR
        cp $TEMP_DIR/$2 .
        rm -rf $TEMP_DIR
}

I have Android Studio version 3.1.2, it shows project full path when you click Build tab in bottom-left location of the studio.

I got this when I didn't type things right. I had

__init.py__ 

instead of

__init__.py

I have encountered the same error as well. I am sure my indentation did not have any problem. Only restarting the python sell solved the problem.

It sounds like the admin has locked the "authentication" node of the web.config, which one can do in the global web.config pretty easily. Or, in a nutshell, this is working as designed.

Basically just target the ID of the select and do this:

var numberOfOptions = $('#selectId option').length;

Update: 2020

You can use the parameter as_frame=True to get pandas dataframes.

If as_frame parameter available (eg. load_iris)

from sklearn import datasets
X,y = datasets.load_iris(return_X_y=True) # numpy arrays

dic_data = datasets.load_iris(as_frame=True)
print(dic_data.keys())

df = dic_data['frame'] # pandas dataframe data + target
df_X = dic_data['data'] # pandas dataframe data only
ser_y = dic_data['target'] # pandas series target only
dic_data['target_names'] # numpy array

If as_frame parameter NOT available (eg. load_boston)

from sklearn import datasets

fnames = [ i for i in dir(datasets) if 'load_' in i]
print(fnames)

fname = 'load_boston'
loader = getattr(datasets,fname)()
df = pd.DataFrame(loader['data'],columns= loader['feature_names'])
df['target'] = loader['target']
df.head(2)

My solution is inspired from the last comment. This is the code of invisible.html

<script src="http://code.jquery.com/jquery-1.8.2.js"></script>
<script type="text/javascript" src="invisible_debut.js" ></script>
<body>
</body>

The clear code of invisible_debut.js is:

$(document).ready(function () {
var ga = document.createElement("script"); //ga is to remember Google Analytics ;-)
ga.type = 'text/javascript';
ga.src = 'invisible.js';
ga.id = 'invisible';
document.body.appendChild(ga);
$('#invisible').remove();});

Notice that at the end I'm removing the created script. invisible.js is:

$(document).ready(function(){
    alert('try to find in the source the js script which did this alert!');
    document.write('It disappeared, my dear!');});

invisible.js doesn't appear in the console, because it has been removed and never in the source code because created by javascript.

Concerning invisible_debut.js, I obfuscated it, which means that it is very complicated to find the url of invisible.js. Not perfect, but enought hard for a normal hacker.

You can remove a string from an array like this:

array = ["Bob", "Same"]
array.remove("Bob")

Well using find is the best option here

just simply use like this

$(".class").click(function(){
        $("this").find('.subclass').css("visibility","visible");
})

and if there are many classes with the same name class its always better to give the class name of parent class like this

$(".parent .class").click(function(){
            $("this").find('.subclass').css("visibility","visible");
    })

To make the function more consistent with the normal means of using a canvas context, the canvas context class can be extended to include a 'fillRoundedRect' method -- that can be called in the same way fillRect is called:

var canv = document.createElement("canvas");
var cctx = canv.getContext("2d");

// If thie canvasContext class doesn't have  a fillRoundedRect, extend it now
if (!cctx.constructor.prototype.fillRoundedRect) {
  // Extend the canvaseContext class with a fillRoundedRect method
  cctx.constructor.prototype.fillRoundedRect = 
    function (xx,yy, ww,hh, rad, fill, stroke) {
      if (typeof(rad) == "undefined") rad = 5;
      this.beginPath();
      this.moveTo(xx+rad, yy);
      this.arcTo(xx+ww, yy,    xx+ww, yy+hh, rad);
      this.arcTo(xx+ww, yy+hh, xx,    yy+hh, rad);
      this.arcTo(xx,    yy+hh, xx,    yy,    rad);
      this.arcTo(xx,    yy,    xx+ww, yy,    rad);
      if (stroke) this.stroke();  // Default to no stroke
      if (fill || typeof(fill)=="undefined") this.fill();  // Default to fill
  }; // end of fillRoundedRect method
} 

The code checks to see if the prototype for the constructor for the canvas context object contains a 'fillRoundedRect' property and adds one -- the first time around. It is invoked in the same manner as the fillRect method:

  ctx.fillStyle = "#eef";  ctx.strokeStyle = "#ddf";
  // ctx.fillRect(10,10, 200,100);
  ctx.fillRoundedRect(10,10, 200,100, 5);

The method uses the arcTo method as Grumdring did. In the method, this is a reference to the ctx object. The stroke argument defaults to false if undefined. The fill argument defaults to fill the rectangle if undefined.

(Tested on Firefox, I don't know if all implementations permit extension in this manner.)

I found it working for me by setting this variable directly on Azure platorm (if you use it). Just select your web app -> configuration -> application settings and add the variable and its value, then press Save button.

import requests
