This is my solution, for any list object you can use this code for convert to xml layout. KeyFather is your principal tag and KeySon is where start your Forech.

public string BuildXml<T>(ICollection<T> anyObject, string keyFather, string keySon)
    {
        var settings = new XmlWriterSettings
        {
            Indent = true
        };
        PropertyDescriptorCollection props = TypeDescriptor.GetProperties(typeof(T));
        StringBuilder builder = new StringBuilder();
        using (XmlWriter writer = XmlWriter.Create(builder, settings))
        {
            writer.WriteStartDocument();
            writer.WriteStartElement(keyFather);
            foreach (var objeto in anyObject)
            {
                writer.WriteStartElement(keySon);
                foreach (PropertyDescriptor item in props)
                {
                    writer.WriteStartElement(item.DisplayName);
                    writer.WriteString(props[item.DisplayName].GetValue(objeto).ToString());
                    writer.WriteEndElement();
                }
                writer.WriteEndElement();
            }
            writer.WriteFullEndElement();
            writer.WriteEndDocument();
            writer.Flush();
            return builder.ToString();
        }
    }

use defaultDate()

Set the date to highlight on first opening if the field is blank. Specify either an actual date via a Date object or as a string in the current [[UI/Datepicker#option-dateFormat|dateFormat]], or a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null for today.

try this

$("[name=trainingStartFromDate]").datepicker({ dateFormat: 'dd-mm-yy', changeYear: true,defaultDate: new Date()});
$("[name=trainingStartToDate]").datepicker({ dateFormat: 'dd-mm-yy', changeYear: true,defaultDate: +15}); 

You can use jQuery's attr() function, like $("#id").attr('src',"source").

find . -type f | xargs file | grep "ASCII text" | awk -F: '{print $1}'

Use find command to list all files, use file command to verify they are text (not tar,key), finally use awk command to filter and print the result.

I don't think HTTP is limited to POST in multipart or x-www-form-urlencoded. The Content-Type Header is orthogonal to the HTTP POST method (you can fill MIME type which suits you). This is also the case for typical HTML representation based webapps (e.g. json payload became very popular for transmitting payload for ajax requests).

Regarding Restful API over HTTP the most popular content-types I came in touch with are application/xml and application/json.

application/xml:

• data-size: XML very verbose, but usually not an issue when using compression and thinking that the write access case (e.g. through POST or PUT) is much more rare as read-access (in many cases it is <3% of all traffic). Rarely there where cases where I had to optimize the write performance
• existence of non-ascii chars: you can use utf-8 as encoding in XML
• existence of binary data: would need to use base64 encoding
• filename data: you can encapsulate this inside field in XML

application/json

• data-size: more compact less that XML, still text, but you can compress
• non-ascii chars: json is utf-8
• binary data: base64 (also see json-binary-question)
• filename data: encapsulate as own field-section inside json

binary data as own resource

I would try to represent binary data as own asset/resource. It adds another call but decouples stuff better. Example images:

POST /images
Content-type: multipart/mixed; boundary="xxxx" 
... multipart data

201 Created
Location: http://imageserver.org/../foo.jpg  

In later resources you could simply inline the binary resource as link:

<main-resource>
 ...
 <link href="http://imageserver.org/../foo.jpg"/>
</main-resource>

You need junit-dep.jar because the junit.jar has a copy of old Hamcrest classes.

Even I faced the same problem in my XMPP notification application, receivers message needs to be added back to list view (implemented with ArrayList). When I tried to add the receiver content through MessageListener (separate thread), application quits with above error. I solved this by adding the content to my arraylist & setListviewadapater through runOnUiThread method which is part of Activity class. This solved my problem.

You can use reptyr:

sudo apt install reptyr
reptyr pid

I found that in Ruby, you can pass two arguments to send_keys

Like this:

element.send_keys(:control, 'A')

Similar to Nick's contribution, I came to the same solution for reindexing an array, but enhanced the function a little since from PHP version 5.4, it doesn't work because of passing variables by reference. Example reindexing function is then like this using use keyword closure:

function indexArrayByElement($array, $element)
{
    $arrayReindexed = [];
    array_walk(
        $array,
        function ($item, $key) use (&$arrayReindexed, $element) {
            $arrayReindexed[$item[$element]] = $item;
        }
    );
    return $arrayReindexed;
}

Do not use regular expressions to parse HTML.

But if you ever need to find all regexp matches in a string, use the findall function.

import re
line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
matches = re.findall('<form>(.*?)</form>', line, re.DOTALL)
print(matches)

# Output: ['Form 1', 'Form 2']

My personal preference is to delete the branch name after I’m done with a topic branch.

Instead of trying to use the branch name to explain the meaning of the branch, I start the subject line of the commit message in the first commit on that branch with “Branch:” and include further explanations in the body of the message if the subject does not give me enough space.

The branch name in my use is purely a handle for referring to a topic branch while working on it. Once work on the topic branch has concluded, I get rid of the branch name, sometimes tagging the commit for later reference.

That makes the output of git branch more useful as well: it only lists long-lived branches and active topic branches, not all branches ever.

i can handle it like that ;

svg.selectAll("rect")
    .data(zones)
    .enter()
    .append("rect")
    .attr("id", function (d) { return "zone" + d.zone; })
    .attr("class", "zone")
    .attr("x", function (d, i) {
        if (parseInt(i / (wcount)) % 2 == 0) {
            this.xcor = (i % wcount) * zoneW;
        }
        else {
            this.xcor = (zoneW * (wcount - 1)) - ((i % wcount) * zoneW);
        }

        return this.xcor;
    })

and anymore you can find x coordinate

svg.select("#zone1").on("click",function(){alert(this.xcor});

The operation is not allowed in chrome. You can either use a HTTP server(Tomcat) or you use Firefox instead.

Try this awesome ink-html library

import print from 'ink-html'
// const print = require('ink-html').default

// js
print(window.querySelector('#printable'))
// Vue.js
print(this.$refs.printable.$el)

Only one answer by Srivathsa Harish Venkataramana mentioned track by which is indeed a solution for this!

Here is an example along with Plunker (link below) of how to use track by in select ng-options:

<select ng-model="selectedCity"
        ng-options="city as city.name for city in cities track by city.id">
  <option value="">-- Select City --</option>
</select>

If selectedCity is defined on angular scope, and it has id property with the same value as any id of any city on the cities list, it'll be auto selected on load.

Here is Plunker for this: http://plnkr.co/edit/1EVs7R20pCffewrG0EmI?p=preview

See source documentation for more details: https://code.angularjs.org/1.3.15/docs/api/ng/directive/select

We can take a simple example.

Consider a table named TableA with the following values:

id  firstname                   lastname                    Mark
-------------------------------------------------------------------
1   arun                        prasanth                    40
2   ann                         antony                      45
3   sruthy                      abc                         41
6   new                         abc                         47
1   arun                        prasanth                    45
1   arun                        prasanth                    49
2   ann                         antony                      49

GROUP BY

The SQL GROUP BY clause can be used in a SELECT statement to collect data across multiple records and group the results by one or more columns.

In more simple words GROUP BY statement is used in conjunction with the aggregate functions to group the result-set by one or more columns.

Syntax:

SELECT expression1, expression2, ... expression_n, 
       aggregate_function (aggregate_expression)
FROM tables
WHERE conditions
GROUP BY expression1, expression2, ... expression_n;

We can apply GROUP BY in our table:

select SUM(Mark)marksum,firstname from TableA
group by id,firstName

Results:

marksum  firstname
----------------
94      ann                      
134     arun                     
47      new                      
41      sruthy   

In our real table we have 7 rows and when we apply GROUP BY id, the server group the results based on id:

In simple words:

here GROUP BY normally reduces the number of rows returned by rolling them up and calculating Sum() for each row.

PARTITION BY

Before going to PARTITION BY, let us look at the OVER clause:

According to the MSDN definition:

OVER clause defines a window or user-specified set of rows within a query result set. A window function then computes a value for each row in the window. You can use the OVER clause with functions to compute aggregated values such as moving averages, cumulative aggregates, running totals, or a top N per group results.

PARTITION BY will not reduce the number of rows returned.

We can apply PARTITION BY in our example table:

SELECT SUM(Mark) OVER (PARTITION BY id) AS marksum, firstname FROM TableA

Result:

marksum firstname 
-------------------
134     arun                     
134     arun                     
134     arun                     
94      ann                      
94      ann                      
41      sruthy                   
47      new  

Look at the results - it will partition the rows and returns all rows, unlike GROUP BY.

hey all...i had a similar problem with my cms system. i needed a hard path for some security aspects. think the best way is like rob wrote. for quick an dirty coding think this works also..:-)

<?php
$path   = getcwd(); 
$myfile = "/test.inc.php";

/* 

getcwd () points to: /usr/srv/apache/htdocs/myworkingdir (as example)

echo ($path.$myfile);
would return...

/usr/srv/apache/htdocs/myworkingdir/test.inc.php

access outside your working directory is not allowed.
*/


includ_once ($path.$myfile);

//some code

nice day strtok

set is used to assign a reference to an object. The C equivalent would be

 int i;
int* ref_i;

i = 4; // Assigning a value (in VBA: i = 4)
ref_i = &i; //assigning a reference (in VBA: set ref_i = i)

As a workaround a generic "ObjectHolder" can be used. See code example below.

The sample output is:

name: John Doe
dob:1953-12-17
name: Jim Miller
dob:1947-04-18

so the Person parameter has been modified since it's wrapped in the Holder which is passed by value - the generic param inside is a reference where the contents can be modified - so actually a different person is returned and the original stays as is.

/**
 * show work around for missing call by reference in java
 */
public class OutparamTest {

 /**
  * a test class to be used as parameter
  */
 public static class Person {
   public String name;
     public String dob;
     public void show() {
      System.out.println("name: "+name+"\ndob:"+dob);
   }
 }

 /**
  * ObjectHolder (Generic ParameterWrapper)
  */
 public static class ObjectHolder<T> {
    public ObjectHolder(T param) {
     this.param=param;
    }
    public T param;
 }

 /**
  * ObjectHolder is substitute for missing "out" parameter
  */
 public static void setPersonData(ObjectHolder<Person> personHolder,String name,String dob) {
    // Holder needs to be dereferenced to get access to content
    personHolder.param=new Person();
    personHolder.param.name=name;
    personHolder.param.dob=dob;
 } 

  /**
   * show how it works
   */
  public static void main(String args[]) {
    Person jim=new Person();
    jim.name="Jim Miller";
    jim.dob="1947-04-18";
    ObjectHolder<Person> testPersonHolder=new ObjectHolder(jim);
    // modify the testPersonHolder person content by actually creating and returning
    // a new Person in the "out parameter"
    setPersonData(testPersonHolder,"John Doe","1953-12-17");
    testPersonHolder.param.show();
    jim.show();
  }
}

Just use the *args parameter, which allows you to pass as many arguments as you want after your a,b,c. You would have to add some logic to map args->c,d,e,f but its a "way" of overloading.

def myfunc(a,b, *args, **kwargs):
   for ar in args:
      print ar
myfunc(a,b,c,d,e,f)

And it will print values of c,d,e,f

Similarly you could use the kwargs argument and then you could name your parameters.

def myfunc(a,b, *args, **kwargs):
      c = kwargs.get('c', None)
      d = kwargs.get('d', None)
      #etc
myfunc(a,b, c='nick', d='dog', ...)

And then kwargs would have a dictionary of all the parameters that are key valued after a,b

It should be mentioned that it is an option to completely leave authentication issues to the front controller, e.g. an Apache Webserver and evaluate the HttpServletRequest.getRemoteUser() instead, which is the JAVA representation for the REMOTE_USER environment variable. This allows also sophisticated log in designs such as Shibboleth authentication. Filtering Requests to a servlet container through a web server is a good design for production environments, often mod_jk is used to do so.

This one worked fine for me.

  String cc2 = "2202";
  String text2 = String.valueOf(Character.toChars(Integer.parseInt(cc2, 16)));

Now text2 will have ?.

Another solution is mentioned in MDN's parseFloat page

It provides a filter function to do strict parsing

var filterFloat = function (value) {
    if(/^(\-|\+)?([0-9]+(\.[0-9]+)?|Infinity)$/
      .test(value))
      return Number(value);
  return NaN;
}


console.log(filterFloat('421'));               // 421
console.log(filterFloat('-421'));              // -421
console.log(filterFloat('+421'));              // 421
console.log(filterFloat('Infinity'));          // Infinity
console.log(filterFloat('1.61803398875'));     // 1.61803398875
console.log(filterFloat('421e+0'));            // NaN
console.log(filterFloat('421hop'));            // NaN
console.log(filterFloat('hop1.61803398875'));  // NaN

And then you can use isNaN to check if it is NaN

$langs = Language::all()->toArray();
return View::make('NAATIMockTest.Admin.Language.index', [
    'langs' => $langs
]);

then in view

<script type="text/javascript">
    var langs = {{json_encode($langs)}};
    console.log(langs);
</script>

Its not pretty tho

functionName() : ReturnType { ... }

Yes, it's possible to use inline if-expressions:

{{ 'Update' if files else 'Continue' }}

If you want to do this without a bunch of server-side processing within the page, it might be a feasible idea to blow the text value into a hidden field (using PHP). Then you can use jQuery to process the hidden field value.

Whatever floats your boat :)

I got the same error when using % as a percent character in my format string. The solution to this is to double up the %%.

In case where multiple columns identify unique row (e.g relations table ) there you can use following

Use row id e.g. emp_dept(empid, deptid, startdate, enddate) suppose empid and deptid are unique and identify row in that case

select oed.empid, count(oed.empid) 
from emp_dept oed 
where exists ( select * 
               from  emp_dept ied 
                where oed.rowid <> ied.rowid and 
                       ied.empid = oed.empid and 
                      ied.deptid = oed.deptid )  
        group by oed.empid having count(oed.empid) > 1 order by count(oed.empid);

and if such table has primary key then use primary key instead of rowid, e.g id is pk then

select oed.empid, count(oed.empid) 
from emp_dept oed 
where exists ( select * 
               from  emp_dept ied 
                where oed.id <> ied.id and 
                       ied.empid = oed.empid and 
                      ied.deptid = oed.deptid )  
        group by oed.empid having count(oed.empid) > 1 order by count(oed.empid);

Hmm, there are a few things going wrong here.

for f in os.listdir(src_dir):
    os.path.join(src_dir, f)

You're not storing the result of join. This should be something like:

for f in os.listdir(src_dir):
    f = os.path.join(src_dir, f)

This open call is is the cause of your IOError. (Because without storing the result of the join above, f was still just 'file.csv', not 'src_dir/file.csv'.)

Also, the syntax:

with open(f): 

is close, but the syntax isn't quite right. It should be with open(file_name) as file_object:. Then, you use to the file_object to perform read or write operations.

And finally:

write(line)

You told python what you wanted to write, but not where to write it. Write is a method on the file object. Try file_object.write(line).

Edit: You're also clobbering your input file. You probably want to open the output file and write lines to it as you're reading them in from the input file.

See: input / output in python.

You can also use map:

a = [1, 1, 1, 1, 1]
b = 1
list(map(lambda x: x + b, a))

It gives:

[2, 2, 2, 2, 2]

You have to specify any one of the above phase to resolve the above error. In most of the situations, this would have occurred due to running the build from the eclipse environment.

instead of mvn clean package or mvn package you can try only package its work fine for me

Here is my answer

private fun openFolder() {
    val location = "/storage/emulated/0/Download/";
    val intent = Intent(Intent.ACTION_VIEW)
    val myDir: Uri = FileProvider.getUriForFile(context, context.applicationContext.packageName + ".provider", File(location))
    intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
    intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
        intent.setDataAndType(myDir,  DocumentsContract.Document.MIME_TYPE_DIR)
    else  intent.setDataAndType(myDir,  "*/*")

    if (intent.resolveActivityInfo(context.packageManager, 0) != null)
    {
        context.startActivity(intent)
    }
    else
    {
        // if you reach this place, it means there is no any file
        // explorer app installed on your device
        CustomToast.toastIt(context,context.getString(R.string.there_is_no_file_explorer_app_present_text))
    }
}

Here why I used FileProvider - android.os.FileUriExposedException: file:///storage/emulated/0/test.txt exposed beyond app through Intent.getData()

I. Plain XSLT 1.0 solution:

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()" name="split">
  <xsl:param name="pText" select="."/>
  <xsl:if test="string-length($pText)">
   <xsl:if test="not($pText=.)">
    <br />
   </xsl:if>
   <xsl:value-of select=
    "substring-before(concat($pText,';'),';')"/>
   <xsl:call-template name="split">
    <xsl:with-param name="pText" select=
     "substring-after($pText, ';')"/>
   </xsl:call-template>
  </xsl:if>
 </xsl:template>
</xsl:stylesheet>

when applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

produces the wanted, corrected result:

123 Elm Street<br />PO Box 222<br />c/o James Jones

II. FXSL 1 (for XSLT 1.0):

Here we just use the FXSL template str-map (and do not have to write recursive template for the 999th time):

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:f="http://fxsl.sf.net/"
xmlns:testmap="testmap"
exclude-result-prefixes="xsl f testmap"
>
   <xsl:import href="str-dvc-map.xsl"/>

   <testmap:testmap/>

   <xsl:output omit-xml-declaration="yes" indent="yes"/>

   <xsl:template match="/">
     <xsl:variable name="vTestMap" select="document('')/*/testmap:*[1]"/>
     <xsl:call-template name="str-map">
       <xsl:with-param name="pFun" select="$vTestMap"/>
       <xsl:with-param name="pStr" select=
       "'123 Elm Street;PO Box 222;c/o James Jones'"/>
     </xsl:call-template>
   </xsl:template>

    <xsl:template name="replace" mode="f:FXSL"
         match="*[namespace-uri() = 'testmap']">
      <xsl:param name="arg1"/>

      <xsl:choose>
       <xsl:when test="not($arg1=';')">
        <xsl:value-of select="$arg1"/>
       </xsl:when>
       <xsl:otherwise><br /></xsl:otherwise>
      </xsl:choose>
    </xsl:template>
</xsl:stylesheet>

when this transformation is applied on any XML document (not used), the same, wanted correct result is produced:

123 Elm Street<br/>PO Box 222<br/>c/o James Jones

III. Using XSLT 2.0

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()">
  <xsl:for-each select="tokenize(.,';')">
   <xsl:sequence select="."/>
   <xsl:if test="not(position() eq last())"><br /></xsl:if>
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

when this transformation is applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

the wanted, correct result is produced:

123 Elm Street<br />PO Box 222<br />c/o James Jones

We can try

iris %>% 
      select_(.dots= setdiff(names(.),drop.cols))

It can be done using inner query Like this

$query = "SELECT * 
            FROM (SELECT Category  
                FROM currency_rates                 
                ORDER BY id DESC) as rows               
            GROUP BY currency";

To clarify camflan's explanation, let's suppose you have

• the rule url(regex=r'^user/(?P<username>\w{1,50})/$', view='views.profile_page')
• a in incoming request for http://domain/user/thaiyoshi/?message=Hi

The URL dispatcher rule will catch parts of the URL path (here "user/thaiyoshi/") and pass them to the view function along with the request object.

The query string (here message=Hi) is parsed and parameters are stored as a QueryDict in request.GET. No further matching or processing for HTTP GET parameters is done.

This view function would use both parts extracted from the URL path and a query parameter:

def profile_page(request, username=None):
    user = User.objects.get(username=username)
    message = request.GET.get('message')

As a side note, you'll find the request method (in this case "GET", and for submitted forms usually "POST") in request.method. In some cases it's useful to check that it matches what you're expecting.

Update: When deciding whether to use the URL path or the query parameters for passing information, the following may help:

• use the URL path for uniquely identifying resources, e.g. /blog/post/15/ (not /blog/posts/?id=15)
• use query parameters for changing the way the resource is displayed, e.g. /blog/post/15/?show_comments=1 or /blog/posts/2008/?sort_by=date&direction=desc
• to make human friendly URLs, avoid using ID numbers and use e.g. dates, categories and/or slugs: /blog/post/2008/09/30/django-urls/

The first 30 seconds of this video shows how to use the global search feature of Phpmyadmin and it works. it will search every table for a string.

This solution can be applied only if the issue is on a WordPress installation!

If you don't have FTP access or too lazy to edit files,

You can use Increase Maximum Upload File Size plugin to increase the maximum upload file size.

This is what I went through on Amazon/AWS EMR v5. (Adapted from the previous answers), to have Maven and Java8.

sudo wget https://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo
sudo yum install -y apache-maven
sudo alternatives --config java

pick Java8

sudo alternatives --config javac

pick Java8

Now, if you run:

mvn -version

You should get:

Apache Maven 3.5.2 (138edd61fd100ec658bfa2d307c43b76940a5d7d; 2017-10-18T07:58:13Z)
Maven home: /usr/share/apache-maven
Java version: 1.8.0_171, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.171-8.b10.38.amzn1.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "4.14.47-56.37.amzn1.x86_64", arch: "amd64", family: “unix"

    int i = 7;
    char number = Integer.toString(i).charAt(0);
    System.out.println(number);

You can solve Q2 if you have the sum of both lists and the product of both lists.

(l1 is the original, l2 is the modified list)

d = sum(l1) - sum(l2)
m = mul(l1) / mul(l2)

We can optimise this since the sum of an arithmetic series is n times the average of the first and last terms:

n = len(l1)
d = (n/2)*(n+1) - sum(l2)

Now we know that (if a and b are the removed numbers):

a + b = d
a * b = m

So we can rearrange to:

a = s - b
b * (s - b) = m

And multiply out:

-b^2 + s*b = m

And rearrange so the right side is zero:

-b^2 + s*b - m = 0

Then we can solve with the quadratic formula:

b = (-s + sqrt(s^2 - (4*-1*-m)))/-2
a = s - b

Sample Python 3 code:

from functools import reduce
import operator
import math
x = list(range(1,21))
sx = (len(x)/2)*(len(x)+1)
x.remove(15)
x.remove(5)
mul = lambda l: reduce(operator.mul,l)
s = sx - sum(x)
m = mul(range(1,21)) / mul(x)
b = (-s + math.sqrt(s**2 - (-4*(-m))))/-2
a = s - b
print(a,b) #15,5

I do not know the complexity of the sqrt, reduce and sum functions so I cannot work out the complexity of this solution (if anyone does know please comment below.)

Boost tuple would be my preferred choice for a generalized system of returning more than one value from a function.

Possible example:

include "boost/tuple/tuple.hpp"

tuple <int,int> divide( int dividend,int divisor ) 

{
  return make_tuple(dividend / divisor,dividend % divisor )
}

Try

yum list installed | grep reponame

It works.

In case you want to use the string from XML, you can do something like this:

strings.xml (the "CDATA" part is important, otherwise it won't work)

<string name="test">
     <![CDATA[
 <b>bold!</b> normal
    ]]>
</string>

layout file

<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity">

    <TextView
        android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:layout_gravity="center" />

</FrameLayout>

code

textView.text = HtmlCompat.fromHtml(getString(R.string.test), HtmlCompat.FROM_HTML_MODE_LEGACY)

Either use COUNT in your MySQL query or do a SELECT * FROM table and do:

$result = mysql_query("SELECT * FROM table");
$rows = mysql_num_rows($result);
echo "There are " . $rows . " rows in my table.";

David, Error comes Microsoft Office Excel has stopped working. Two options check online for a solution and close the programme and other option Close the program I am sure error is in my array but I am reading everything and seem this is way to define arrays.

Old question which has an accepted answer already, but I like to think of these two isolation levels in terms of how they change the locking behavior in SQL Server. This might be helpful for those who are debugging deadlocks like I was.

READ COMMITTED (default)

Shared locks are taken in the SELECT and then released when the SELECT statement completes. This is how the system can guarantee that there are no dirty reads of uncommitted data. Other transactions can still change the underlying rows after your SELECT completes and before your transaction completes.

REPEATABLE READ

Shared locks are taken in the SELECT and then released only after the transaction completes. This is how the system can guarantee that the values you read will not change during the transaction (because they remain locked until the transaction finishes).

You can try:

<label id ="label_id"></label>
 $("#label_id").html('value');

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

You can delete all unwanted characters from a string using its translate() method with None for the table argument followed by a string containing the character(s) you want removed for its deletechars argument.

lst = ['x', 3, 'b']

print str(lst).translate(None, "'")

# [x, 3, b]

If you're using a version of Python before 2.6, you'll need to use the string module's translate() function instead because the ability to pass None as the table argument wasn't added until Python 2.6. Using it looks like this:

import string

print string.translate(str(lst), None, "'")

Using the string.translate() function will also work in 2.6+, so using it might be preferable.

If you're just needing to export to excel, you can use the export data wizard. Right click the database, Tasks->Export data.

All my experience tells me that safest way of persisting enums anywhere is to use additional code value or id (some kind of evolution of @jeebee answer). This could be a nice example of an idea:

enum Race {
    HUMAN ("human"),
    ELF ("elf"),
    DWARF ("dwarf");

    private final String code;

    private Race(String code) {
        this.code = code;
    }

    public String getCode() {
        return code;
    }
}

Now you can go with any persistence referencing your enum constants by it's code. Even if you'll decide to change some of constant names, you always can save code value (e.g. DWARF("dwarf") to GNOME("dwarf"))

Ok, dive some more deeper with this conception. Here is some utility method, that helps you find any enum value, but first lets extend our approach.

interface CodeValue {
    String getCode();
}

And let our enum implement it:

enum Race implement CodeValue {...}

This is the time for magic search method:

static <T extends Enum & CodeValue> T resolveByCode(Class<T> enumClass, String code) {
    T[] enumConstants = enumClass.getEnumConstants();
    for (T entry : enumConstants) {
        if (entry.getCode().equals(code)) return entry;
    }
    // In case we failed to find it, return null.
    // I'd recommend you make some log record here to get notified about wrong logic, perhaps.
    return null;
}

And use it like a charm: Race race = resolveByCode(Race.class, "elf")

You can do it with strtol, like this:

char *str = "ab234cid*(s349*(20kd", *p = str;
while (*p) { // While there are more characters to process...
    if ( isdigit(*p) || ( (*p=='-'||*p=='+') && isdigit(*(p+1)) )) {
        // Found a number
        long val = strtol(p, &p, 10); // Read number
        printf("%ld\n", val); // and print it.
    } else {
        // Otherwise, move on to the next character.
        p++;
    }
}

Link to ideone.

Because the dot is inside character class (square brackets []).

Take a look at http://www.regular-expressions.info/reference.html, it says (under char class section):

Any character except ^-]\ add that character to the possible matches for the character class.

I simply used the string 'center left' for the location, like in matlab. I imported pylab from matplotlib.

see the code as follow:

from matplotlib as plt
from matplotlib.font_manager import FontProperties
t = A[:,0]
sensors = A[:,index_lst]
    
for i in range(sensors.shape[1]):
    plt.plot(t,sensors[:,i])
        
plt.xlabel('s')
plt.ylabel('°C')
lgd = plt.legend(loc='center left', bbox_to_anchor=(1, 0.5),fancybox = True, shadow = True)

Database Clustering is actually a mode of synchronous replication between two or possibly more nodes with an added functionality of fault tolerance added to your system, and that too in a shared nothing architecture. By shared nothing it means that the individual nodes actually don't share any physical resources like disk or memory.

As far as keeping the data synchronized is concerned, there is a management server to which all the data nodes are connected along with the SQL node to achieve this(talking specifically about MySQL).

Now about the differences: load balancing is just one result that could be achieved through clustering, the others include high availability, scalability and fault tolerance.

1. Connect to sys.
2. Give your password for sys.
3. Unlock hr user by running following query:

alter user hr identified by hr account unlock;

4. Then, Click on new connection

5. Give connection name as HR_ORCL Username: hr Password: hr Connection Type: Basic Role: default Hostname: localhost Port: 1521 SID: xe

6. Click on test and Connect

ASP.Net 4.0 added the boolean ShowHeaderWhenEmpty property.

http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.gridview.showheaderwhenempty.aspx

<asp:GridView runat="server" ID="GridView1" ShowHeaderWhenEmpty="true" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField HeaderText="First Name" DataField="FirstName" />
        <asp:BoundField HeaderText="Last Name" DataField="LastName" />
    </Columns>
</asp:GridView>

Note: the headers will not appear unless DataBind() is called with something other than null.

GridView1.DataSource = New List(Of String)
GridView1.DataBind()

Using Aggs u can easily do that. Writing down query for now.

GET index/_search
{
  "size":0,
  "aggs": {
    "source": {
      "terms": {
        "field": "field",
        "size": 100000
      }
    }
  }
 }

This would return the different values of field with there doc counts.

I think that this would help:

<select name="select_1">
    <optgroup label="First optgroup category">
      <option selected="selected" value="0">Select element</option>
      <option value="2">Option 1</option>
      <option value="3">Option 2</option>
      <option value="4">Option 3</option>
    </optgroup>
    <optgroup label="Second optgroup category">
      <option value="5">Option 4</option>
      <option value="6">Option 5</option>
      <option value="7">Option 6</option>
    </optgroup>
</select>

You can use map :

List<String> names = 
    personList.stream()
              .map(Person::getName)
              .collect(Collectors.toList());

EDIT :

In order to combine the Lists of friend names, you need to use flatMap :

List<String> friendNames = 
    personList.stream()
              .flatMap(e->e.getFriends().stream())
              .collect(Collectors.toList());

    <style>
    background: url(images/Untitled-2.fw.png);
background-repeat:no-repeat;
background-position:center;
background-size: cover;
    </style>

You can just look for the value that corresponds with the key and then check if the input is equal to the key.

for key in PIX0:
    NUM = input("Which standard has a resolution of %s " % PIX0[key])
    if NUM == key:

Also, you will have to change the last line to fit in, so it will print the key instead of the value if you get the wrong answer.

print("I'm sorry but thats wrong. The correct answer was: %s." % key )

Also, I would recommend using str.format for string formatting instead of the % syntax.

Your full code should look like this (after adding in string formatting)

PIX0 = {"QVGA":"320x240", "VGA":"640x480", "SVGA":"800x600"}

for key in PIX0:
    NUM = input("Which standard has a resolution of {}".format(PIX0[key]))
    if NUM == key:
        print ("Nice Job!")
        count = count + 1
    else:
        print("I'm sorry but that's wrong. The correct answer was: {}.".format(key))

You can only use await in an async method, and Main cannot be async.

You'll have to use your own async-compatible context, call Wait on the returned Task in the Main method, or just ignore the returned Task and just block on the call to Read. Note that Wait will wrap any exceptions in an AggregateException.

If you want a good intro, see my async/await intro post.

Go for the obvious first: Are you referencing well the jquery-ui.js file?

Try using the network tab of firebug to find if it is loaded, or the Information\View javascript code of the Web Developer Toolbar.

@Rounded, A swift 5.1 property wrapper Example :

struct GameResult {

    var score: Decimal
}

var result = GameResult()
result.score = 3.14159265358979
print(result.score) // 3.1416

These days, everyone uses Pillow, a friendly PIL fork, over PIL.

Instead of: sudo pip install pil

Do: sudo pip install pillow

If there is a possibility that the element does not exist in the XML I would test both that the element is present and that the string-length is greater than zero:

<xsl:choose>
    <xsl:when test="categoryName and string-length(categoryName) &gt; 0">
        <xsl:value-of select="categoryName " />
    </xsl:when>
    <xsl:otherwise>
        <xsl:value-of select="other" />
    </xsl:otherwise>
</xsl:choose>

First shift the column:

df['gdp'] = df['gdp'].shift(-1)

Second remove the last row which contains an NaN Cell:

df = df[:-1]

Third reset the index:

df = df.reset_index(drop=True)

If your data has changed every once,you will notice dont tracing the table.for example some table update id ([key]) using tigger.If you tracing ,you will get same id and get the issue.

You can use IndexOf() like this:

string title = "STRING";

if (title.IndexOf("string", 0, StringComparison.CurrentCultureIgnoreCase) != -1)
{
    // The string exists in the original
}

Since 0 (zero) can be an index, you check against -1.

MSDN

The zero-based index position of value if that string is found, or -1 if it is not. If value is String.Empty, the return value is 0.

I will let the code speak for itself:

Mesh mesh = new Mesh();
BoundingVolume vol = new BoundingVolume();
mesh.boundingVolume = vol;
vol.mesh = mesh;
vol.compute(); 

Do you like it? Here is with the setters:

Mesh mesh = new Mesh();
BoundingVolume vol = new BoundingVolume();
mesh.setBoundingVolume(vol);

Try this using uniqid and hexdec,

echo hexdec(uniqid());

Make sure that the following are taken care of:

1. Your import statement & its path

2. The tag name of your component you specified in the components {....} block

an alternative answer is the judicious use of tables and rowspan. by setting all table cells on the preceeding line (except the main content one) to be rowspan="2" you will always get a one cell hole at the bottom of your main table cell that you can always put valign="bottom".

You can also set its height to be the minimum you need for one line. Thus you will always get your favourite line of text at the bottom regardless of how much space the rest of the text takes up.

I tried all the div answers, I was unable to get them to do what I needed.

<table>
<tr>
   <td valign="top">
     this is just some random text
     <br> that should be a couple of lines long and
     <br> is at the top of where we need the bottom tag line
   </td>
   <td rowspan="2">
     this<br/>
     this<br/>
     this<br/>
     this<br/>
     this<br/>
     this<br/>
     this<br/>
     this<br/>
     this<br/>
     this<br/>
     this<br/>
     is really<br/>
     tall
  </td>
</tr>
<tr>
  <td valign="bottom">
      now this is the tagline we need on the bottom
  </td>
</tr>
</table>

in your WebApiConfig >> Register () You have to change to

config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{action}/{id}",
                defaults: new { id = RouteParameter.Optional }

Here the routeTemplate, is added with {action}

Your code is

urlpatterns = [
    url(r'^$', 'myapp.views.home'),
    url(r'^contact/$', 'myapp.views.contact'),
    url(r'^login/$', 'django.contrib.auth.views.login'),
]

change it to following as you're importing include() function :

urlpatterns = [
    url(r'^$', views.home),
    url(r'^contact/$', views.contact),
    url(r'^login/$', views.login),
]

First of all, read the warning! It says do not run composer as root! Secondly, you're probably using Xammp on your local which has the required php libraries as default.

But in your server you're missing ext-dom. php-xml has all the related packages you need. So, you can simply install it by running:

sudo apt-get update
sudo apt install php-xml

Most likely you are missing mbstring too. If you get the error, install this package as well with:

sudo apt-get install php-mbstring

Then run:

composer update
composer require cviebrock/eloquent-sluggable

If you're using GCC, you might want to have a look at Optimizing the next_pow2() function by Lockless Inc.. This page describes a way to use built-in function builtin_clz() (count leading zero) and later use directly x86 (ia32) assembler instruction bsr (bit scan reverse), just like it's described in another answer's link to gamedev site. This code might be faster than those described in previous answer.

By the way, if you're not going to use assembler instruction and 64bit data type, you can use this

/**
 * return the smallest power of two value
 * greater than x
 *
 * Input range:  [2..2147483648]
 * Output range: [2..2147483648]
 *
 */
__attribute__ ((const))
static inline uint32_t p2(uint32_t x)
{
#if 0
    assert(x > 1);
    assert(x <= ((UINT32_MAX/2) + 1));
#endif

    return 1 << (32 - __builtin_clz (x - 1));
}

window.location is just what you need. Other thing you can do is to create anchor element and simulate click on it

$("<a href='your url'></a>").click(); 

If you want to extend it just because you need Not-Swipeable behaviour, you dont need to do it. ViewPager2 provides nice property called : isUserInputEnabled

I just put gawk on Solaris 10 M4000: So, gawk is the cuplrit on the $NF-1 vs. $(NF-1) issue. Next question what does POSIX say? per:

http://www.opengroup.org/onlinepubs/009695399/utilities/awk.html

There is no direction one way or the other. Not good. gawk implies subtraction, other awks imply field number or subtraction. hmm.

One should check if QtyToRepair is updated at first.

ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
   ON [dbo].[SCHEDULE]
   AFTER UPDATE
AS 
BEGIN
SET NOCOUNT ON;
    IF UPDATE (QtyToRepair) 
    BEGIN
        UPDATE SCHEDULE 
        SET modified = GETDATE()
           , ModifiedUser = SUSER_NAME()
           , ModifiedHost = HOST_NAME()
        FROM SCHEDULE S INNER JOIN Inserted I 
            ON S.OrderNo = I.OrderNo and S.PartNumber =    I.PartNumber
        WHERE S.QtyToRepair <> I.QtyToRepair
    END
END

When we get this error while running our java application, check if we have some class name or package names starting with ”java.”, if so change the package name. This is happening because your package name is colliding with java system file names.

I had this problem, and turns out the problem was that I had used

new SimpleJdbcCall(jdbcTemplate)
    .withProcedureName("foo")

instead of

new SimpleJdbcCall(jdbcTemplate)
    .withFunctionName("foo")

Somewhat a little prettified solution by @Vin-G.

import datetime

def monthrange(start, finish):
  months = (finish.year - start.year) * 12 + finish.month + 1 
  for i in xrange(start.month, months):
    year  = (i - 1) / 12 + start.year 
    month = (i - 1) % 12 + 1
    yield datetime.date(year, month, 1)

When checking for white space the c# method uses the Unicode standard. White space includes spaces, tabs, carriage returns and many other non-printing character codes. So you are better of using:

function isNullOrWhiteSpace(str){
    return str == null || str.replace(/\s/g, '').length < 1;
}

Seems a banal solution but I usually put simply a TextView in the front of the spinner. The whole Xml looks like this. (hey guys, don't shoot me, I know that some of you don't like this kind of marriage):

<FrameLayout
    android:id="@+id/selectTypesLinear"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >

    <Spinner
        android:id="@+id/spinnerExercises"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:entries="@array/exercise_spinner_entries"
        android:prompt="@string/exercise_spinner_prompt"
     />                         
    <TextView
        android:id="@+id/spinnerSelectText"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="Hey! Select this guy!"
        android:gravity="center"
        android:background="#FF000000" />


</FrameLayout>

Then I hide the TextView when an Item was selected. Obviously the background color of the TextView should be the same as the Spinner. Works on Android 4.0. Don't know on older versions.

Yes. Because the Spinner calls setOnItemSelectedListener at the beginning, the hiding of the textview could be a little bit tricky, but can be done this way:

    Boolean controlTouched;

    exerciseSpinner.setOnTouchListener(new OnTouchListener() {


        @Override
        public boolean onTouch(View v, MotionEvent event) {
            controlTouched = true; // I touched it but but not yet selected an Item.
            return false;
        }

    });
    exerciseSpinner.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            if (controlTouched) { // Are you sure that I touched it with my fingers and not someone else  ?
                spinnerSelText.setVisibility(View.GONE);
            }
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
        }

    });

Instead of retrieving the file content as a single string, it can be handy to store the content as a list of all lines the file comprises:

with open('Path/to/file', 'r') as content_file:
    content_list = content_file.read().strip().split("\n")

As can be seen, one needs to add the concatenated methods .strip().split("\n") to the main answer in this thread.

Here, .strip() just removes whitespace and newline characters at the endings of the entire file string, and .split("\n") produces the actual list via splitting the entire file string at every newline character \n.

Moreover, this way the entire file content can be stored in a variable, which might be desired in some cases, instead of looping over the file line by line as pointed out in this previous answer.

Where does it fail?

I agree that your issue is probably that your dataset of 600,000 rows is probably just too large. I see that you are then adding it to Session. If you are using Sql session state, it will have to serialize that data as well.

Even if you dispose of your objects properly, you will always have at least 2 copies of this dataset in memory if you run it twice, once in session, once in procedural code. This will never scale in a web application.

Do the math, 600,000 rows, at even 1-128 bit guid per row would yield 9.6 megabytes (600k * 128 / 8) of just data, not to mention the dataset overhead.

Trim down your results.

Runnable is an interface defined as so:

interface Runnable {
    public void run();
}

To make a class which uses it, just define the class as (public) class MyRunnable implements Runnable {

It can be used without even making a new Thread. It's basically your basic interface with a single method, run, that can be called.

If you make a new Thread with runnable as it's parameter, it will call the run method in a new Thread.

It should also be noted that Threads implement Runnable, and that is called when the new Thread is made (in the new thread). The default implementation just calls whatever Runnable you handed in the constructor, which is why you can just do new Thread(someRunnable) without overriding Thread's run method.

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

With @Query , we can use pagination as well where you need to pass object of Pageable class at end of JPA method

For example:

Pageable pageableRequest = new PageRequest(page, size, Sort.Direction.DESC, rollNo);

Where, page = index of page (index start from zero)
size = No. of records
Sort.Direction = Sorting as per rollNo
rollNo = Field in User class

UserRepository repo
repo.findByFirstname("John", pageableRequest);

public interface UserRepository extends JpaRepository<User, Long> {

  @Query(value = "SELECT * FROM USER WHERE FIRSTNAME = :firstname)
  Page<User> findByLastname(@Param("firstname") String firstname, Pageable pageable);
}

Only solution in OSX and its variant.

ln -s /usr/local/bin/python /usr/local/opt/python/bin/python2.7

Now we can easily do this using the aspect-ratio ^ref property

.container {
  display: grid;
  grid-template-columns: repeat(3, minmax(0, 1fr)); /* 3 columns */
  grid-gap: 10px;
}

.container>* {
  aspect-ratio: 1 / 1; /* a square ratio */
  border: 1px solid;
  
  /* center content */
  display: flex;
  align-items: center;
  justify-content: center;
  text-align: center;
}

img {
  max-width: 100%;
  display: block;
}

<div class="container">
  <div> some content here </div>
  <div><img src="https://picsum.photos/id/25/400/400"></div>
  <div>
    <h1>a title</h1>
  </div>
  <div>more and more content <br>here</div>
  <div>
    <h2>another title</h2>
  </div>
  <div><img src="https://picsum.photos/id/104/400/400"></div>
</div>

Also like below where we can have a variable number of columns

.container {
  display: grid;
  grid-template-columns: repeat(auto-fill, minmax(250px, 1fr));
  grid-gap: 10px;
}

.container>* {
  aspect-ratio: 1 / 1; /* a square ratio */
  border: 1px solid;
  
  /* center content */
  display: flex;
  align-items: center;
  justify-content: center;
  text-align: center;
}

img {
  max-width: 100%;
  display: block;
}

<div class="container">
  <div> some content here </div>
  <div><img src="https://picsum.photos/id/25/400/400"></div>
  <div>
    <h1>a title</h1>
  </div>
  <div>more and more content <br>here</div>
  <div>
    <h2>another title</h2>
  </div>
  <div><img src="https://picsum.photos/id/104/400/400"></div>
  <div>more and more content <br>here</div>
  <div>
    <h2>another title</h2>
  </div>
  <div><img src="https://picsum.photos/id/104/400/400"></div>
</div>

This post will go through the following topics:

• Merging with index under different conditions
  • options for index-based joins: merge, join, concat
  • merging on indexes
  • merging on index of one, column of other
• effectively using named indexes to simplify merging syntax

_{BACK TO TOP}

Index-based joins

TL;DR

There are a few options, some simpler than others depending on the use case.

1. DataFrame.merge with left_index and right_index (or left_on and right_on using names indexes)
   • supports inner/left/right/full
   • can only join two at a time
   • supports column-column, index-column, index-index joins
2. DataFrame.join (join on index)
   • supports inner/left (default)/right/full
   • can join multiple DataFrames at a time
   • supports index-index joins
3. pd.concat (joins on index)
   • supports inner/full (default)
   • can join multiple DataFrames at a time
   • supports index-index joins

Index to index joins

Setup & Basics

import pandas as pd
import numpy as np

np.random.seed([3, 14])
left = pd.DataFrame(data={'value': np.random.randn(4)}, 
                    index=['A', 'B', 'C', 'D'])    
right = pd.DataFrame(data={'value': np.random.randn(4)},  
                     index=['B', 'D', 'E', 'F'])
left.index.name = right.index.name = 'idxkey'

left
           value
idxkey          
A      -0.602923
B      -0.402655
C       0.302329
D      -0.524349

right
 
           value
idxkey          
B       0.543843
D       0.013135
E      -0.326498
F       1.385076

Typically, an inner join on index would look like this:

left.merge(right, left_index=True, right_index=True)

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

Other joins follow similar syntax.

Notable Alternatives

1. DataFrame.join defaults to joins on the index. DataFrame.join does a LEFT OUTER JOIN by default, so how='inner' is necessary here.

    left.join(right, how='inner', lsuffix='_x', rsuffix='_y')
   
             value_x   value_y
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   Note that I needed to specify the lsuffix and rsuffix arguments since join would otherwise error out:

    left.join(right)
    ValueError: columns overlap but no suffix specified: Index(['value'], dtype='object')
   

   Since the column names are the same. This would not be a problem if they were differently named.

    left.rename(columns={'value':'leftvalue'}).join(right, how='inner')
   
            leftvalue     value
    idxkey                     
    B       -0.402655  0.543843
    D       -0.524349  0.013135
   

2. pd.concat joins on the index and can join two or more DataFrames at once. It does a full outer join by default, so how='inner' is required here..

    pd.concat([left, right], axis=1, sort=False, join='inner')
   
               value     value
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   For more information on concat, see this post.

Index to Column joins

To perform an inner join using index of left, column of right, you will use DataFrame.merge a combination of left_index=True and right_on=....

right2 = right.reset_index().rename({'idxkey' : 'colkey'}, axis=1)
right2
 
  colkey     value
0      B  0.543843
1      D  0.013135
2      E -0.326498
3      F  1.385076

left.merge(right2, left_index=True, right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

Other joins follow a similar structure. Note that only merge can perform index to column joins. You can join on multiple columns, provided the number of index levels on the left equals the number of columns on the right.

join and concat are not capable of mixed merges. You will need to set the index as a pre-step using DataFrame.set_index.

Effectively using Named Index [pandas >= 0.23]

If your index is named, then from pandas >= 0.23, DataFrame.merge allows you to specify the index name to on (or left_on and right_on as necessary).

left.merge(right, on='idxkey')

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

For the previous example of merging with the index of left, column of right, you can use left_on with the index name of left:

left.merge(right2, left_on='idxkey', right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

Hope this helps some1 thx_joxin

You close the second Scanner which closes the underlying InputStream, therefore the first Scanner can no longer read from the same InputStream and a NoSuchElementException results.

The solution: For console apps, use a single Scanner to read from System.in.

Aside: As stated already, be aware that Scanner#nextInt does not consume newline characters. Ensure that these are consumed before attempting to call nextLine again by using Scanner#newLine().

See: Do not create multiple buffered wrappers on a single InputStream

This clearly shows java pid 9862 is the culprit.

After reading all the issues with the added functions I decided I need something more accurate. Here's what I came up with that works for me.

If you need to specifically validate hostnames (they must start and end with an alphanumberic character and contain only alphanumerics and hyphens) this function should be enough.

function is_valid_domain($domain) {
    // Check for starting and ending hyphen(s)
    if(preg_match('/-./', $domain) || substr($domain, 1) == '-') {
        return false;
    }

    // Detect and convert international UTF-8 domain names to IDNA ASCII form
    if(mb_detect_encoding($domain) != "ASCII") {
        $idn_dom = idn_to_ascii($domain);
    } else {
        $idn_dom = $domain;
    }

    // Validate
    if(filter_var($idn_dom, FILTER_VALIDATE_DOMAIN, FILTER_FLAG_HOSTNAME) != false) {
        return true;
    }
    return false;
}

Note that this function will work on most (haven't tested all languages) LTR languages. It will not work on RTL languages.

is_valid_domain('a');                                                                       Y
is_valid_domain('a.b');                                                                     Y

In my case, I solved adding return in the onClientClick:

Code Behind

function verify(){
  if (document.getElementById("idName").checked == "") {
    alert("Fill the field");
    return false;
  }
}

Design Surface

<asp:Button runat="server" ID="send" Text="Send" onClientClick="return verify()" />

My TS lint was complaining about other solutions, so the solution that was working for me was:

item: Array<Type1 | Type2>

if there's only one type, it's fine to use:

item: Type1[]

For some of my technical experiments, I was trying to figure out how beneficial and feasible it is to implement bots for different chat platforms in terms of market share and so possibilities of adaptation. Especially when you have bankruptly failed twice, it's important to validate ideas and fail more faster.

Popular chat platforms like Messenger, Slack, Skype etc. have happily (in the sense officially) provided APIs for bots to interact with, but WhatsApp has not yet provided any API.

However, since many years, a lot of activities has happened around this - struggle towards automated interaction with WhatsApp platform:

1. Bots App Bots App is interesting because it shows that something is really tried and tested.

2. Yowsup A project still actively developed to interact with WhatsApp platform.

3. Yallagenie Yallagenie claim that there is a demo bot which can be interacted with at +971 56 112 6652

4. Hubtype Hubtype is working towards having a bot platform for WhatsApp for business.

5. Fred Fred's task was to automate WhatsApp conversations, however since it was not officially supported by WhatsApp - it was shut down.

6. Oye Gennie A bot blocked by WhatsApp.

7. App/Website to WhatsApp We can use custom URL schemes and Android intent system to interact with WhatsApp but still NOT WhatsApp API.

8. Chat API daemon Probably created by inspecting the API calls in WhatsApp web version. NOT affiliated with WhatsApp.

9. WhatsBot Deactivated WhatsApp bot. Created during a hackathon.

10. No API claim WhatsApp co-founder clearly stated this in a conference that they did not had any plans for APIs for WhatsApp.

11. Bot Ware They probably are expecting WhatsApp to release their APIs for chat bot platforms.

12. Vixi They seems to be talking about how some platform which probably would work for WhatsApp. There is no clarity as such.

13. Unofficial API This API can shut off any time.

    And the number goes on...

If you are going to find an index once then using "index" method is fine. However, if you are going to search your data more than once then I recommend using bisect module. Keep in mind that using bisect module data must be sorted. So you sort data once and then you can use bisect. Using bisect module on my machine is about 20 times faster than using index method.

Here is an example of code using Python 3.8 and above syntax:

import bisect
from timeit import timeit

def bisect_search(container, value):
    return (
      index 
      if (index := bisect.bisect_left(container, value)) < len(container) 
      and container[index] == value else -1
    )

data = list(range(1000))
# value to search
value = 666

# times to test
ttt = 1000

t1 = timeit(lambda: data.index(value), number=ttt)
t2 = timeit(lambda: bisect_search(data, value), number=ttt)

print(f"{t1=:.4f}, {t2=:.4f}, diffs {t1/t2=:.2f}")

Output:

t1=0.0400, t2=0.0020, diffs t1/t2=19.60

wxPython has support for playing wav files on Windows and Unix - I am not sure if this includes Macs. However it only support wav files as far as I can tell - it does not support other common formats such as mp3 or ogg.

something like:

DELIMITER //

CREATE PROCEDURE alluser()
BEGIN
   SELECT *
   FROM users;
END //

DELIMITER ;

than:

SHOW CREATE PROCEDURE alluser

gives result:

'alluser', 'STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER', 'CREATE DEFINER=`root`@`localhost` PROCEDURE `alluser`()
BEGIN
   SELECT *
   FROM users;
END'

>>> dict([('hi','goodbye')])
{'hi': 'goodbye'}

Or:

>>> [ dict([i]) for i in (('CSCO', 21.14), ('CSCO', 21.14), ('CSCO', 21.14), ('CSCO', 21.14)) ]
[{'CSCO': 21.14}, {'CSCO': 21.14}, {'CSCO': 21.14}, {'CSCO': 21.14}]

I like consolas too.

This method seems ok in all browsers, if you set the onclick with a jQuery event:

<a href="javascript:;">Click me!</a>

As said before, href="#" with change the url hash and can trigger data re/load if you use a History (or ba-bbq) JS plugin.

You need to split the line first.

import csv

with open('log.txt', 'r') as in_file:
    stripped = (line.strip() for line in in_file)
    lines = (line.split(",") for line in stripped if line)
    with open('log.csv', 'w') as out_file:
        writer = csv.writer(out_file)
        writer.writerow(('title', 'intro'))
        writer.writerows(lines)

I tried experimenting with the answers given. My personal finding came out to be:

git rm -r --cached .

And then

git add .

This seemed to make my working directory nice and clean. You can put your fileName in place of the dot.

I know this question is a bit old but i would suggest to use some cachebraking hash in the url of the javascript. This works perfectly in production as well as during development because you can have both infinite cache times and intant updates when changes occur.

Lets assume you have a javascript file /js/script.min.js, but in the referencing html/php file you do not use the actual path but:

<script src="/js/script.<?php echo md5(filemtime('/js/script.min.js')); ?>.min.js"></script>

So everytime the file is changed, the browser gets a different url, which in turn means it cannot be cached, be it locally or on any proxy inbetween.

To make this work you need nginx to rewrite any request to /js/script.[0-9a-f]{32}.min.js to the original filename. In my case i use the following directive (for css also):

location ~* \.(css|js)$ {
                expires max;
                add_header Pragma public;
                etag off;
                add_header Cache-Control "public";
                add_header Last-Modified "";
                rewrite  "^/(.*)\/(style|script)\.min\.([\d\w]{32})\.(js|css)$" /$1/$2.min.$4 break;
        }

I would guess that the filemtime call does not even require disk access on the server as it should be in linux's file cache. If you have doubts or static html files you can also use a fixed random value (or incremental or content hash) that is updated when your javascript / css preprocessor has finished or let one of your git hooks change it.

In theory you could also use a cachebreaker as a dummy parameter (like /js/script.min.js?cachebreak=0123456789abcfef), but then the file is not cached at least by some proxies because of the "?".

Here is how it works for me with no Servlet use.

Let's say I am trying to access web.xml in project/WebContent/WEB-INF/web.xml

1. In project property Source-tab add source folder by pointing to the parent container for WEB-INF folder (in my case WebContent )

2. Now let's use class loader:

   InputStream inStream = class.getClass().getClassLoader().getResourceAsStream("Web-INF/web.xml")
   

git log currentbranch..otherbranch will give you the list of commits that will go into the current branch if you do a merge. The usual arguments to log which give details on the commits will give you more information.

git diff currentbranch otherbranch will give you the diff between the two commits that will become one. This will be a diff that gives you everything that will get merged.

Would these help?

How about that?

<?php
    while($items = array_pop($lists)){
        echo "<ul>";
        foreach($items as $item){
            echo "<li>$item</li>";
        }
        echo "</ul>";
    }
?>

If using an interactive debugger is OK for you, you can try perldebug.

Dim myRow() As Data.DataRow
myRow = dt.Select("MyColumnName = 'SomeColumnTitle'")
myRow(0)("SomeOtherColumnTitle") = strValue

Code above instantiates a DataRow. Where "dt" is a DataTable, you get a row by selecting any column (I know, sounds backwards). Then you can then set the value of whatever row you want (I chose the first row, or "myRow(0)"), for whatever column you want.

Do you mean how long is the array itself, or how many customerids are in it?

Because the answer to the first question is easy: 5 (or if you don't want to hard-code it, Ben Stott's answer).

But the answer to the other question cannot be automatically determined. Presumably you have allocated an array of length 5, but will initially have 0 customer IDs in there, and will put them in one at a time, and your question is, "how many customer IDs have I put into the array?"

C can't tell you this. You will need to keep a separate variable, int numCustIds (for example). Every time you put a customer ID into the array, increment that variable. Then you can tell how many you have put in.

Short answer:

try using reimport: a full featured reload for Python.

Longer answer:

It looks like this question was asked/answered prior to the release of reimport, which bills itself as a "full featured reload for Python":

This module intends to be a full featured replacement for Python's reload function. It is targeted towards making a reload that works for Python plugins and extensions used by longer running applications.

Reimport currently supports Python 2.4 through 2.6.

By its very nature, this is not a completely solvable problem. The goal of this module is to make the most common sorts of updates work well. It also allows individual modules and package to assist in the process. A more detailed description of what happens is on the overview page.

Note: Although the reimport explicitly supports Python 2.4 through 2.6, I've been trying it on 2.7 and it seems to work just fine.

Nginx can act as a reverse proxy server which works just like a project manager. When it gets a request it analyses it and forwards the request to upstream(project members) or handles itself. Nginx has two ways of handling a request based on how its configured.

• serve the request

• forward the request to another server

  server{
   server_name mydomain.com sub.mydomain.com;
  
   location /{ 
    proxy_pass http://127.0.0.1:8000;  
    proxy_set_header Host $host;
    proxy_pass_request_headers on;  
   }
  
   location /static/{
     alias /my/static/files/path;
   }
  

  }

Server the request

With this configuration, when the request url is mydomain.com/static/myjs.js it returns the myjs.js file in /my/static/files/path folder. When you configure nginx to serve static files, it handles the request itself.

forward the request to another server

When the request url is mydomain.com/dothis nginx will forwards the request to http://127.0.0.1:8000. The service which is running on the localhost 8000 port will receive the request and returns the response to nginx and nginx returns the response to the client.

When you run node.js server on the port 8000 nginx will forward the request to node.js. Write node.js logic and handle the request. That's it you have your nodejs server running behind the nginx server.

If you wish to run any other services other than nodejs just run another service like Django, flask, php on different ports and config it in nginx.

replace Range("A1") = "Asdf" with Range("A1").value = "Asdf"

The fastest way is using -0:

const num = "12.34" - 0;

I know that this code snippet works for recognizing an option click (at least in Chrome and FF). Furthermore, it works if the element wasn't there on DOM load. I usually use this when I input sections of inputs into a single select element and I don't want the section title to be clicked.

$(document).on('click', 'option[value="disableme"]', function(){
    $('option[value="disableme"]').prop("selected", false);
});

Is this what you're looking for?

System.Web.Script.Serialization.JavaScriptSerializer

The following should work fine.

string[] arr = new string[] {""};

Scanner sc = new Scanner(System.in); 
String name = sc.nextLine();
String surname = sc.nextLine();
Statement statement = connection.createStatement();
String query = "INSERT INTO STUDENT VALUES("+'"name"'+","+'"surname"'+")";
statement.executeQuery();

Do not miss to add '"----"' when concat the string.

This orders a list vertically without bullet points. In just one line!

li {
    display: block;
}

In Year 2019, we can use Javascript's ES6 Spread syntax to do it concisely and efficiently

data = [...data, {"label": 2, "value": 13}]

Examples

var data = [_x000D_
      {"label" : "1", "value" : 12},_x000D_
      {"label" : "1", "value" : 12},_x000D_
      {"label" : "1", "value" : 12},_x000D_
    ];_x000D_
    _x000D_
data = [...data, {"label" : "2", "value" : 14}] _x000D_
console.log(data)

For your case (i know it was in 2011), we can do it with map() & forEach() like below

var lab = ["1","2","3","4"];_x000D_
var val = [42,55,51,22];_x000D_
_x000D_
//Using forEach()_x000D_
var data = [];_x000D_
val.forEach((v,i) => _x000D_
   data= [...data, {"label": lab[i], "value":v}]_x000D_
)_x000D_
_x000D_
//Using map()_x000D_
var dataMap = val.map((v,i) => _x000D_
 ({"label": lab[i], "value":v})_x000D_
)_x000D_
_x000D_
console.log('data: ', data);_x000D_
console.log('dataMap : ', dataMap);

I've never had a good memory for exact wording, but in my database class I think the professor always said something like:

The data depends on the key [1NF], the whole key [2NF] and nothing but the key [3NF].

Using the accepted answer and knowing that Object.values() is proposed in ECMAScript 2017 Draft you can extend Object with method:

if(Object.values == null) {
    Object.values = function(obj) {
        var arr, o;
        arr = new Array();
        for(o in obj) { arr.push(obj[o]); }
        return arr;
    }
}

string radioListValue = RadioButtonList.Text;

ast.literal_eval (located in ast.py) parses the tree with ast.parse first, then it evaluates the code with quite an ugly recursive function, interpreting the parse tree elements and replacing them with their literal equivalents. Unfortunately the code is not at all expandable, so to add Decimal to the code you need to copy all the code and start over.

For a slightly easier approach, you can use ast.parse module to parse the expression, and then the ast.NodeVisitor or ast.NodeTransformer to ensure that there is no unwanted syntax or unwanted variable accesses. Then compile with compile and eval to get the result.

The code is a bit different from literal_eval in that this code actually uses eval, but in my opinion is simpler to understand and one does not need to dig too deep into AST trees. It specifically only allows some syntax, explicitly forbidding for example lambdas, attribute accesses (foo.__dict__ is very evil), or accesses to any names that are not deemed safe. It parses your expression fine, and as an extra I also added Num (float and integer), list and dictionary literals.

Also, works the same on 2.7 and 3.3

import ast
import decimal

source = "(Decimal('11.66985'), Decimal('1e-8'),"\
    "(1,), (1,2,3), 1.2, [1,2,3], {1:2})"

tree = ast.parse(source, mode='eval')

# using the NodeTransformer, you can also modify the nodes in the tree,
# however in this example NodeVisitor could do as we are raising exceptions
# only.
class Transformer(ast.NodeTransformer):
    ALLOWED_NAMES = set(['Decimal', 'None', 'False', 'True'])
    ALLOWED_NODE_TYPES = set([
        'Expression', # a top node for an expression
        'Tuple',      # makes a tuple
        'Call',       # a function call (hint, Decimal())
        'Name',       # an identifier...
        'Load',       # loads a value of a variable with given identifier
        'Str',        # a string literal

        'Num',        # allow numbers too
        'List',       # and list literals

Session.destroy(callback)

Destroys the session and will unset the req.session property. Once complete, the callback will be invoked.

↓ Secure way ↓ ?

req.session.destroy((err) => {

})

↓ Unsecure way ↓ ?

req.logout();
res.redirect('/') // can be called before logout is done

Sounds obvious, but make sure that you are not explicitly ignoring the type:

modelBuilder.Ignore<MyType>();

A more intuitive explanation would be :-

The square root of 100 is 10. Let's say a x b = 100, for various pairs of a and b.

If a == b, then they are equal, and are the square root of 100, exactly. Which is 10.

If one of them is less than 10, the other has to be greater. For example, 5 x 20 == 100. One is greater than 10, the other is less than 10.

Thinking about a x b, if one of them goes down, the other must get bigger to compensate, so the product stays at 100. They pivot around the square root.

The square root of 101 is about 10.049875621. So if you're testing the number 101 for primality, you only need to try the integers up through 10, including 10. But 8, 9, and 10 are not themselves prime, so you only have to test up through 7, which is prime.

Because if there's a pair of factors with one of the numbers bigger than 10, the other of the pair has to be less than 10. If the smaller one doesn't exist, there is no matching larger factor of 101.

If you're testing 121, the square root is 11. You have to test the prime integers 1 through 11 (inclusive) to see if it goes in evenly. 11 goes in 11 times, so 121 is not prime. If you had stopped at 10, and not tested 11, you would have missed 11.

You have to test every prime integer greater than 2, but less than or equal to the square root, assuming you are only testing odd numbers.

Try to use ftp.nlst(dir).

However, note that if the folder is empty, it might throw an error:

files = []

try:
    files = ftp.nlst()
except ftplib.error_perm, resp:
    if str(resp) == "550 No files found":
        print "No files in this directory"
    else:
        raise

for f in files:
    print f

This happens to me while working with XCode (I'm using the most current version of XCode in 2019...). I'm using, CMake for build integration. Using the following directive in CMakeLists.txt fixed it for me:

set(CMAKE_CXX_STANDARD 14).

Example:

cmake_minimum_required(VERSION 3.14.0)
set(CMAKE_CXX_STANDARD 14)

# Rest of your declarations...

You can prototype object and then call object instance every time you want to use and change object:

function object () {
  this.x = 5;
  this.y = 5;
}
var obj1 = new object();
var obj2 = new object();
obj2.x = 6;
console.log(obj1.x); //logs 5

You can also pass arguments to object constructor

function object (x, y) {
   this.x = x;
   this.y = y;
}
var obj1 = new object(5, 5);
var obj2 = new object(6, 6);
console.log(obj1.x); //logs 5
console.log(obj2.x); //logs 6

Hope this is helpful.

For :

abc:number|string;

Use the JavaScript operator typeof:

if (typeof abc === "number") {
    // do something
}

TypeScript understands typeof

This is called a typeguard.

More

For classes you would use instanceof e.g.

class Foo {}
class Bar {} 

// Later
if (fooOrBar instanceof Foo){
  // TypeScript now knows that `fooOrBar` is `Foo`
}

There are also other type guards e.g. in etc https://basarat.gitbooks.io/typescript/content/docs/types/typeGuard.html

This happens when you index a row/column with a number that is larger than the dimensions of your dataframe. For instance, getting the eleventh column when you have only three.

import pandas as pd

df = pd.DataFrame({'Name': ['Mark', 'Laura', 'Adam', 'Roger', 'Anna'],
                   'City': ['Lisbon', 'Montreal', 'Lisbon', 'Berlin', 'Glasgow'],
                   'Car': ['Tesla', 'Audi', 'Porsche', 'Ford', 'Honda']})

You have 5 rows and three columns:

    Name      City      Car
0   Mark    Lisbon    Tesla
1  Laura  Montreal     Audi
2   Adam    Lisbon  Porsche
3  Roger    Berlin     Ford
4   Anna   Glasgow    Honda

Let's try to index the eleventh column (it doesn't exist):

df.iloc[:, 10] # there is obviously no 11th column

IndexError: single positional indexer is out-of-bounds

If you are a beginner with Python, remember that df.iloc[:, 10] would refer to the eleventh column.

Single Threaded Event Loop Model Processing Steps:

• Clients Send request to Web Server.

• Node JS Web Server internally maintains a Limited Thread pool to provide services to the Client Requests.

• Node JS Web Server receives those requests and places them into a Queue. It is known as “Event Queue”.

• Node JS Web Server internally has a Component, known as “Event Loop”. Why it got this name is that it uses indefinite loop to receive requests and process them.

• Event Loop uses Single Thread only. It is main heart of Node JS Platform Processing Model.

• Event Loop checks any Client Request is placed in Event Queue. If not then wait for incoming requests for indefinitely.

• If yes, then pick up one Client Request from Event Queue

  1. Starts process that Client Request
  2. If that Client Request Does Not requires any Blocking IO Operations, then process everything, prepare response and send it back to client.
  3. If that Client Request requires some Blocking IO Operations like interacting with Database, File System, External Services then it will follow different approach
• Checks Threads availability from Internal Thread Pool
• Picks up one Thread and assign this Client Request to that thread.

• That Thread is responsible for taking that request, process it, perform Blocking IO operations, prepare response and send it back to the Event Loop

I was also facing the same error in my node application today.

Below was my node API.

app.get('azureTable', (req, res) => {
  const tableSvc = azure.createTableService(config.azureTableAccountName, config.azureTableAccountKey);
  const query = new azure.TableQuery().top(1).where('PartitionKey eq ?', config.azureTablePartitionKey);
  tableSvc.queryEntities(config.azureTableName, query, null, (error, result, response) => {
    if (error) { return; }
    res.send(result);
    console.log(result)
  });
});

The fix was very simple, I was missing a slash "/" before my API. So after changing the path from 'azureTable' to '/azureTable', the issue was resolved.

UIWebView *pdfWebView = [[UIWebView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)];

NSURL *targetURL = [NSURL URLWithString:@"http://unec.edu.az/application/uploads/2014/12/pdf-sample.pdf"];
    NSURLRequest *request = [NSURLRequest requestWithURL:targetURL];
    [pdfWebView loadRequest:request];
    [self.view addSubview:pdfWebView];

I know this has been answered with a very high-quality answer. But, in short, you cant have spaces.

#!/bin/bash
STR = "Hello World"
echo $STR

Didn't work because of the spaces around the equal sign. If you were to run...

#!/bin/bash
STR="Hello World"
echo $STR

It would work

Nothing worked for me so far because I was trying to add one jar from lib.

This did not worked:

build/*
!build/libs/*
!build/libs/
!build/libs/myjarfile.jar 

This worked:

!build/libs

Create a new ImageIcon object like this:

ImageIcon img = new ImageIcon(pathToFileOnDisk);

Then set it to your JFrame with setIconImage():

myFrame.setIconImage(img.getImage());

Also checkout setIconImages() which takes a List instead.

Try placing the desired java directory in PATH before not needed java directories in your PATH.

The java.net.URL class is in fact not at all a good way of validating URLs. MalformedURLException is not thrown on all malformed URLs during construction. Catching IOException on java.net.URL#openConnection().connect() does not validate URL either, only tell wether or not the connection can be established.

Consider this piece of code:

    try {
        new URL("http://.com");
        new URL("http://com.");
        new URL("http:// ");
        new URL("ftp://::::@example.com");
    } catch (MalformedURLException malformedURLException) {
        malformedURLException.printStackTrace();
    }

..which does not throw any exceptions.

I recommend using some validation API implemented using a context free grammar, or in very simplified validation just use regular expressions. However I need someone to suggest a superior or standard API for this, I only recently started searching for it myself.

Note It has been suggested that URL#toURI() in combination with handling of the exception java.net. URISyntaxException can facilitate validation of URLs. However, this method only catches one of the very simple cases above.

The conclusion is that there is no standard java URL parser to validate URLs.

If a case-insensitive comparison is acceptable, just use =:

=IF(A1="ENG",1,0)

When you open a folder in VSCode, it will automatically scan the folder for typical project artifacts like project.json or solution files. From the status bar in the lower left side you can switch between solutions and projects.

The problem in your code is that you can't store the memory address of a local variable (local to a function, for example) in a globlar variable:

RectInvoice rect(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(&rect);

There, &rect is a temporary address (stored in the function's activation registry) and will be destroyed when that function end.

The code should create a dynamic variable:

RectInvoice *rect =  new RectInvoice(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(rect);

There you are using a heap address that will not be destroyed in the end of the function's execution. Tell me if it worked for you.

Cheers

Triple quotes are OK to me. You can use ''' foo ''' for docstrings and """ bar """ for comments or vice-versa to make the code more readable.

Since it's not mentioned and it's really helpful:

ctrl-wp

which I memorize as go to the previously selected window.

It works as a there and back command. After having opened a new file from the tree in a new window press ctrl-wp to switch back to the NERDTree and use it again to return to your previous window.

PS: it is worth to mention that ctrl-wp is actually documented as go to the preview window (see: :help preview-window and :help ctrl-w).

It is also the only keystroke which works to switch inside and explore the COC preview documentation window.

The trunk is the main line of development in a SVN repository.

A branch is a side-line of development created to make larger, experimental or disrupting work without annoying users of the trunk version. Also, branches can be used to create development lines for multiple versions of the same product, like having a place to backport bugfixes into a stable release.

Finally, tags are markers to highlight notable revisions in the history of the repository, usually things like "this was released as 1.0".

See the HTML version of "Version Control with Subversion", especially Chapter 4: Branching and Merging or buy it in paper (e.g. from amazon) for an in-depth discussion of the technical details.

As others (e.g. Peter Neubauer below) the underlying implementation as /tags /branches and /trunk directories is only conventional and not in any way enforced by the tools. Violating these conventions leads to confusion all around, as this breaks habits and expectations of others accessing the repository. Special care must be taken to avoid committing new changes into tags, which should be frozen.

I use TortoiseSVN but no Visual Studio integration. I keep the "Check for modifications" dialog open on the second monitor the whole time, so I can track which files I have touched. But see the "Best SVN Tools" question, for more recommendations.

In this case, you might get some differences. Consider a line like:

"foo\tbar "

In this case, if you strip, then you'll get {"foo":"bar"} as the dictionary entry. If you don't strip, you'll get {"foo":"bar "} (note the extra space at the end)

Note that if you use line.split() instead of line.split('\t'), you'll split on every whitespace character and the "striping" will be done during splitting automatically. In other words:

line.strip().split()

is always identical to:

line.split()

but:

line.strip().split(delimiter)

Is not necessarily equivalent to:

line.split(delimiter)

If you use XCode 5 you should do it in a different way.

• Select your UIViewController in UIStoryboard
• Go to the Identity Inspector on the right top pane
• Check the Use Storyboard ID checkbox
• Write a unique id to the Storyboard ID field

Then write your code.

// Override point for customization after application launch.

if (<your implementation>) {
    UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" 
                                                             bundle: nil];
    YourViewController *yourController = (YourViewController *)[mainStoryboard 
      instantiateViewControllerWithIdentifier:@"YourViewControllerID"];
    self.window.rootViewController = yourController;
}

return YES;

Type type = pi.PropertyType;
if(type.IsGenericType && type.GetGenericTypeDefinition()
        == typeof(List<>))
{
    Type itemType = type.GetGenericArguments()[0]; // use this...
}

More generally, to support any IList<T>, you need to check the interfaces:

foreach (Type interfaceType in type.GetInterfaces())
{
    if (interfaceType.IsGenericType &&
        interfaceType.GetGenericTypeDefinition()
        == typeof(IList<>))
    {
        Type itemType = type.GetGenericArguments()[0];
        // do something...
        break;
    }
}

In TS and ES6 you can create a new Set with the property to be unique and compare it's size to the original array.

const values = [_x000D_
  { name: 'someName1' },_x000D_
  { name: 'someName2' },_x000D_
  { name: 'someName3' },_x000D_
  { name: 'someName1' }_x000D_
]_x000D_
_x000D_
const uniqueValues = new Set(values.map(v => v.name));_x000D_
_x000D_
if (uniqueValues.size < values.length) {_x000D_
  console.log('duplicates found')_x000D_
}

If found it was because I had been messing about with netsh http add commands to get IIS Express visible remotely.

The symptoms were:

• the site would fail to connect in a browser
• the site would fail to start (right click IIS Express in the Taskbar and it was missing)
• if I ran Visual Studio as admin it would start in IIS Express and be visible in the browser

The solution was to list all bound sites:

netsh http show urlacl

then delete the one I had recently added:

netsh http delete urlacl url=http://*:54321/

In addition I had removed localhost from the hidden solution folder file .vs\config\application.config for the site:

<bindings>
    <binding protocol="http" bindingInformation="*:54321:" />
</bindings>

so had to put that back:

<bindings>
    <binding protocol="http" bindingInformation="*:54321:localhost" />
</bindings>

 app.get('/category', function(req, res) {
  var string = query
  res.redirect('/?valid=' + string);
});

in the ejs you can directly use valid:

<% var k = valid %>

It's ok to pass an array - in fact it amounts to the same thing

String.format("%s %s", "hello", "world!");

is the same as

String.format("%s %s", new Object[] { "hello", "world!"});

It's just syntactic sugar - the compiler converts the first one into the second, since the underlying method is expecting an array for the vararg parameter.

In VS2015:

• Right-click on Solution
• Select Project Build Order
• Look at the list of projects in Project Build Order
• Build each of your projects in that order
• Inspect the Output

In my case, doing it step-by-step helped discovered what my problem is without all those errors thrown left and right.

If you had to know, I added Entity Framework (EF) 6.1.3 via NuGet when the project was set for .NET 4.5.2. I later downgraded the .NET Framework down to 4, and then the error was more obvious. Via NuGet, I uninstalled EF and re-added it.

You can make symbolic link to you pip3:

I found some useful information in a forum page, quoted below.
From this, mainly the sentences in bold formatting, my answer is:

• Make a bash (shell) script version of your .bat file (like other
  answers, with \ changed to / in file paths). For example:

  # File "example.command":
  #!/bin/bash
  java -cp  ".;./supportlibraries/Framework_Core.jar; ...etc.
  

• Then rename it to have the Mac OS file extension .command.
  That should make the script run using the Terminal app.

• If the app user is going to use a bash script version of the file on Linux
  or run it from the command line, they need to add executable rights
  (change mode bits) using this command, in the folder that has the file:

  chmod +rx [filename].sh
  #or:# chmod +rx [filename].command
  

The forum page question:

Good day, [...] I wondering if there are some "simple" rules to write an equivalent
of the Windows (DOS) bat file. I would like just to click on a file and let it run.

Info from some answers after the question:

Write a shell script, and give it the extension ".command". For example:

#!/bin/bash 
printf "Hello World\n" 

- Mar 23, 2010, Tony T1.

The DOS .BAT file was an attempt to bring to MS-DOS something like the idea of the UNIX script.
In general, UNIX permits you to make a text file with commands in it and run it by simply flagging
the text file as executable (rather than give it a specific suffix). This is how OS X does it.

However, OS X adds the feature that if you give the file the suffix .command, Finder
will run Terminal.app to execute it (similar to how BAT files work in Windows).

Unlike MS-DOS, however, UNIX (and OS X) permits you to specify what interpreter is used
for the script. An interpreter is a program that reads in text from a file and does something
with it. [...] In UNIX, you can specify which interpreter to use by making the first line in the
text file one that begins with "#!" followed by the path to the interpreter. For example [...]

#!/bin/sh
echo Hello World

- Mar 23, 2010, J D McIninch.

Also, info from an accepted answer for Equivalent of double-clickable .sh and .bat on Mac?:

On mac, there is a specific extension for executing shell
scripts by double clicking them: this is .command.

java can not support multiple inheritence.but u can do this in this way

class X
{
}
class Y extends X
{
}
class Z extends Y{
}

To avoid the "however" in Erandac's answer in combination of Daniel's and Salman's answers, one may use one of the following "partition workarounds"

SELECT customerID, myDate

  -- partition ranking works only with CTE / from MySQL 8.0 on
  , RANK() OVER (PARTITION BY customerID ORDER BY dateFrom) AS rank, 

  -- Erandac's method in combination of Daniel's and Salman's
  -- count all items in sequence, maximum reaches row count.
  , IF(customerID=@_lastRank, @_curRank:=@_curRank, @_curRank:=@_sequence+1) AS sequenceRank
  , @_sequence:=@_sequence+1 as sequenceOverAll

  -- Dense partition ranking, works also with MySQL 5.7
  -- remember to set offset values in from clause
  , IF(customerID=@_lastRank, @_nxtRank:=@_nxtRank, @_nxtRank:=@_nxtRank+1 ) AS partitionRank
  , IF(customerID=@_lastRank, @_overPart:=@_overPart+1, @_overPart:=1 ) AS partitionSequence

  , @_lastRank:=customerID
FROM myCustomers, 
  (SELECT @_curRank:=0, @_sequence:=0, @_lastRank:=0, @_nxtRank:=0, @_overPart:=0 ) r
ORDER BY customerID, myDate

The partition ranking in the 3rd variant in this code snippet will return continous ranking numbers. this will lead to a data structur similar to the rank() over partition by result. As an example, see below. In particular, the partitionSequence will always start with 1 for each new partitionRank, using this method:

customerID    myDate   sequenceRank (Erandac)
                          |    sequenceOverAll
                          |     |   partitionRank
                          |     |     | partitionSequence
                          |     |     |    | lastRank

I use SQLite Database Browser for SQLite3 currently and it's pretty useful. Works across Windows/OS X/Linux and is lightweight and fast. Slightly unstable with executing SQL on the DB if it's incorrectly formatted.

Edit: I have recently discovered SQLite Manager, a plugin for Firefox. Obviously you need to run Firefox, but you can close all windows and just run it "standalone". It's very feature complete, amazingly stable and it remembers your databases! It has tonnes of features so I've moved away from SQLite Database Browser as the instability and lack of features is too much to bear.

If you just want to print them:

void binary(unsigned int n)
{
    for(int shift=sizeof(int)*8-1;shift>=0;shift--)
    {
       if (n >> shift & 1)
         printf("1");
       else
         printf("0");

    }
    printf("\n");
} 

it's so easy...converting a date to calendar like this:

Calendar cal=Calendar.getInstance();
DateFormat format=new SimpleDateFormat("yyyy/mm/dd");
format.format(date);
cal=format.getCalendar();

Ahh, found the answer myself:

if (/[a-zA-Z]/.test(num)) {
  alert('Letter Found')
}

Resolved this issue by using http(s) when accessing the endpoint. The route I was accessing was not available over http. So I would say verify the protocols for which the route is available.

I agree with Charles Duffy that a proper XML parser is the right way to go.

But as to what's wrong with your sed command (or did you do it on purpose?).

• $data was not quoted, so $data is subject to shell's word splitting, filename expansion among other things. One of the consequences being that the spacing in the XML snippet is not preserved.

So given your specific XML structure, this modified sed command should work

title=$(sed -ne '/title/{s/.*<title>\(.*\)<\/title>.*/\1/p;q;}' <<< "$data")

Basically for the line that contains title, extract the text between the tags, then quit (so you don't extract the 2nd <title>)

on os x these are the same for me... could this maybe be extra "\r" in windows?

in any case you may be better of with:

contents = File.read("e.tgz")
newFile = File.open("ee.tgz", "w")
newFile.write(contents)

Simple elegant working solution:

img {
  width: 600px;  /*width of parent container*/
  height: 350px; /*height of parent container*/
  object-fit: contain;
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

functional solution

function applyFilters(data, filters) {
  return data.filter(item =>
    Object.keys(filters)
      .map(keyToFilterOn =>
        item[keyToFilterOn].includes(filters[keyToFilterOn]),
      )
      .reduce((x, y) => x && y, true),
  );
}

this should do the job

applyFilters(users, filter);

if ( $('#myfav').children().length > 0 ) {
     // do something
}

This should work. The children() function returns a JQuery object that contains the children. So you just need to check the size and see if it has at least one child.

In my case I used blow code for different environment.

  document.cookie = name +`=; Path=/; Expires=Thu, 01 Jan 1970 00:00:01 GMT;Domain=.${document.domain.split('.').splice(1).join('.')}`;

Just use a simple button instead of a submit button. And call a JavaScript function to handle form submit:

<input type="button" name="submit" value="submit" onclick="submit_form();"/>

Function within a script tag:

function submit_form() {
    if (conditions) {
        document.forms['myform'].submit();
    }
    else {
        returnToPreviousPage();
    }
}

You can also try window.history.forward(-1);

This worked for me. Repeatedly calls a function updating the graph every time.

import matplotlib.pyplot as plt
import matplotlib.animation as anim

def plot_cont(fun, xmax):
    y = []
    fig = plt.figure()
    ax = fig.add_subplot(1,1,1)

    def update(i):
        yi = fun()
        y.append(yi)
        x = range(len(y))
        ax.clear()
        ax.plot(x, y)
        print i, ': ', yi

    a = anim.FuncAnimation(fig, update, frames=xmax, repeat=False)
    plt.show()

"fun" is a function that returns an integer. FuncAnimation will repeatedly call "update", it will do that "xmax" times.

In Unix it is probably easier to use 'tr' command.

cat file1.txt | tr "\r" "\n" > file2.txt

The paint() method supports painting via a Graphics object.

The repaint() method is used to cause paint() to be invoked by the AWT painting thread.

You can use // instead of single /. That converts to int directly.

To run multiple shell commands with ansible you can use the shell module with a multi-line string (note the pipe after shell:), as shown in this example:

  - name: Build nginx 
    shell: |
      cd nginx-1.11.13
      sudo ./configure
      sudo make
      sudo make install

Nothing in the example says that the "classes implementing the same interface". MovieCatalog is a type and CustomerPreferenceDao is another type. Spring can easily tell them apart.

In Spring 2.x, wiring of beans mostly happened via bean IDs or names. This is still supported by Spring 3.x but often, you will have one instance of a bean with a certain type - most services are singletons. Creating names for those is tedious. So Spring started to support "autowire by type".

What the examples show is various ways that you can use to inject beans into fields, methods and constructors.

The XML already contains all the information that Spring needs since you have to specify the fully qualified class name in each bean. You need to be a bit careful with interfaces, though:

This autowiring will fail:

 @Autowired
 public void prepare( Interface1 bean1, Interface1 bean2 ) { ... }

Since Java doesn't keep the parameter names in the byte code, Spring can't distinguish between the two beans anymore. The fix is to use @Qualifier:

 @Autowired
 public void prepare( @Qualifier("bean1") Interface1 bean1,
     @Qualifier("bean2")  Interface1 bean2 ) { ... }

Use CSS background:transparent; to your button/div.

JSFiddle

It should be also mentioned that a named input of type="submit" will be also submitted together with the other form's named fields while a named input type="button" won't.

With other words, in the example below, the named input name=button1 WON'T get submitted while the named input name=submit1 WILL get submitted.

Sample HTML form (index.html):

<form action="checkout.php" method="POST">

  <!-- this won't get submitted despite being named -->
  <input type="button" name="button1" value="a button">

  <!-- this one does; so the input's TYPE is important! -->
  <input type="submit" name="submit1" value="a submit button">

</form>

The PHP script (checkout.php) that process the above form's action:

<?php var_dump($_POST); ?>

Test the above on your local machine by creating the two files in a folder named /tmp/test/ then running the built-in PHP web server from shell:

php -S localhost:3000 -t /tmp/test/

Open your browser at http://localhost:3000 and see for yourself.

One would wonder why would we need to submit a named button? It depends on the back-end script. For instance the WooCommerce WordPress plugin won't process a Checkout page posted unless the Place Order named button is submitted too. If you alter its type from submit to button then this button won't get submitted and thus the Checkout form would never get processed.

This is probably a small detail but you know, the devil is in the details.

LOL, a super lame hack, but at least curl and firefox accepts it:

while true ; do (dd if=/dev/zero count=10000;echo -e "HTTP/1.1\n\n $(date)") | nc -l  1500  ; done

You better replace it soon with something proper!

Ah yes, my nc were not exactly the same as yours, it did not like the -p option.

You can still use sizeWithFont. but, in iOS >= 7.0 method cause crashing if the string contains leading and trailing spaces or end lines \n.

Trimming text before using it

label.text = [label.text stringByTrimmingCharactersInSet:
             [NSCharacterSet whitespaceAndNewlineCharacterSet]];

That's also may apply to sizeWithAttributes and [label sizeToFit].

also, whenever you have nsstringdrawingtextstorage message sent to deallocated instance in iOS 7.0 device it deals with this.

//change it to the columns you need
String[] columns = new String[]{MediaStore.Audio.AudioColumns.DATA}; 
Cursor cursor = contentResolver.query(uri, columns, null, null, null);

I know its old topic, but I'd like to contribute too.

With the newer version of boto3 and python, you can get the files as follow:

import os
import boto3
from botocore.exceptions import ClientError    

client = boto3.client('s3')

bucket = client.list_objects(Bucket=BUCKET_NAME)
for content in bucket["Contents"]:
    key = content["key"]

Keep in mind that this solution not comprehends pagination.

For more information: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/s3.html#S3.Client.list_objects

Make sure the client computer has the same or higher version of the .NET framework that you built your program to.
